This skips parsing the firmware version information from the firmware
file while controller is in bootloader mode. As in bootloader mode,
we are supposed to patch unconditionally.

In Operational firmware mode, 'Minimum FW version' TLV ID is not available.
So, we cannot fetch already running firmware info for comparison against
another build. However, It can be collected using a combination of other
TLV ID's information.

intel_version_tlv parsing
This moves limited_cce and sbe_type checks under bootloader during tlv parsing
as operational firmware don't have access to these values. Any attempt to read
such values in operational firmware will only fetch garbage data.

In order to allow new firmware to load, it first needs to check if the
firmware version on file matches the one loaded if it doesn't, then it
needs to revert to bootloader mode in order to load the new firmware.

Pull scheduler updates from Ingo Molnar:
"Core scheduler updates:
- Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the
preempt=none/voluntary/full boot options (default: full), to allow
distros to build a PREEMPT kernel but fall back to close to
PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via
a boot time selection.
There's also the /debug/sched_debug switch to do this runtime.
This feature is implemented via runtime patching (a new variant of
static calls).
The scope of the runtime patching can be best reviewed by looking
at the sched_dynamic_update() function in kernel/sched/core.c.
( Note that the dynamic none/voluntary mode isn't 100% identical,
for example preempt-RCU is available in all cases, plus the
preempt count is maintained in all models, which has runtime
overhead even with the code patching. )
The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast
majority of distributions, are supposed to be unaffected.
- Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that
was found via rcutorture triggering a hang. The bug is that
rcu_idle_enter() may wake up a NOCB kthread, but this happens after
the last generic need_resched() check. Some cpuidle drivers fix it
by chance but many others don't.
In true 2020 fashion the original bug fix has grown into a 5-patch
scheduler/RCU fix series plus another 16 RCU patches to address the
underlying issue of missed preemption events. These are the initial
fixes that should fix current incarnations of the bug.
- Clean up rbtree usage in the scheduler, by providing & using the
following consistent set of rbtree APIs:
partial-order; less() based:
- rb_add(): add a new entry to the rbtree
- rb_add_cached(): like rb_add(), but for a rb_root_cached
total-order; cmp() based:
- rb_find(): find an entry in an rbtree
- rb_find_add(): find an entry, and add if not found
- rb_find_first(): find the first (leftmost) matching entry
- rb_next_match(): continue from rb_find_first()
- rb_for_each(): iterate a sub-tree using the previous two
- Improve the SMP/NUMA load-balancer: scan for an idle sibling in a
single pass. This is a 4-commit series where each commit improves
one aspect of the idle sibling scan logic.
- Improve the cpufreq cooling driver by getting the effective CPU
utilization metrics from the scheduler
- Improve the fair scheduler's active load-balancing logic by
reducing the number of active LB attempts & lengthen the
load-balancing interval. This improves stress-ng mmapfork
performance.
- Fix CFS's estimated utilization (util_est) calculation bug that can
result in too high utilization values
Misc updates & fixes:
- Fix the HRTICK reprogramming & optimization feature
- Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
- Reduce dl_add_task_root_domain() overhead
- Fix uprobes refcount bug
- Process pending softirqs in flush_smp_call_function_from_idle()
- Clean up task priority related defines, remove *USER_*PRIO and
USER_PRIO()
- Simplify the sched_init_numa() deduplication sort
- Documentation updates
- Fix EAS bug in update_misfit_status(), which degraded the quality
of energy-balancing
- Smaller cleanups"

Pull power management updates from Rafael Wysocki:
"These add a new power capping facility allowing aggregate power
constraints to be applied to sets of devices in a distributed manner,
add a new CPU ID to the RAPL power capping driver and improve it, drop
a cpufreq driver belonging to a platform that is not supported any
more, drop two redundant cpufreq driver flags, update cpufreq drivers
(intel_pstate, brcmstb-avs, qcom-hw), update the operating performance
points (OPP) framework (code cleanups, new helpers, devfreq-related
modifications), clean up devfreq, extend the PM clock layer, update
the cpupower utility and make assorted janitorial changes.
Specifics:
- Add new power capping facility called DTPM (Dynamic Thermal Power
Management), based on the existing power capping framework, to
allow aggregate power constraints to be applied to sets of devices
in a distributed manner, along with a CPU backend driver based on
the Energy Model (Daniel Lezcano, Dan Carpenter, Colin Ian King).
- Add AlderLake Mobile support to the Intel RAPL power capping driver
and make it use the topology interface when laying out the system
topology (Zhang Rui, Yunfeng Ye).
- Drop the cpufreq tango driver belonging to a platform that is not
supported any more (Arnd Bergmann).
- Drop the redundant CPUFREQ_STICKY and CPUFREQ_PM_NO_WARN cpufreq
driver flags (Viresh Kumar).
- Update cpufreq drivers:
* Fix max CPU frequency discovery in the intel_pstate driver and
make janitorial changes in it (Chen Yu, Rafael Wysocki, Nigel
Christian).
* Fix resource leaks in the brcmstb-avs-cpufreq driver (Christophe
JAILLET).
* Make the tegra20 driver use the resource-managed API (Dmitry
Osipenko).
* Enable boost support in the qcom-hw driver (Shawn Guo).
- Update the operating performance points (OPP) framework:
* Clean up the OPP core (Dmitry Osipenko, Viresh Kumar).
* Extend the OPP API by adding new helpers to it (Dmitry Osipenko,
Viresh Kumar).
* Allow required OPPs to be used for devfreq devices and update
the devfreq governor code accordingly (Saravana Kannan).
* Prepare the framework for introducing new dev_pm_opp_set_opp()
helper (Viresh Kumar).
* Drop dev_pm_opp_set_bw() and update related drivers (Viresh
Kumar).
* Allow lazy linking of required-OPPs (Viresh Kumar).
- Simplify and clean up devfreq somewhat (Lukasz Luba, Yang Li,
Pierre Kuo).
- Update the generic power domains (genpd) framework:
* Use device's next wakeup to determine domain idle state (Lina
Iyer).
* Improve initialization and debug (Dmitry Osipenko).
* Simplify computations (Abaci Team).
- Make janitorial changes in the core code handling system sleep and
PM-runtime (Bhaskar Chowdhury, Bjorn Helgaas, Rikard Falkeborn,
Zqiang).
- Update the MAINTAINERS entry for the exynos cpuidle driver and drop
DEBUG definition from intel_idle (Krzysztof Kozlowski, Tom Rix).
- Extend the PM clock layer to cover clocks that must sleep (Nicolas
Pitre).
- Update the cpupower utility:
* Update cpupower command, add support for AMD family 0x19 and
clean up the code to remove many of the family checks to make
future family updates easier (Nathan Fontenot, Robert Richter).
* Add Makefile dependencies for install targets to allow building
cpupower in parallel rather than serially (Ivan Babrou).
- Make janitorial changes in power management Kconfig (Lukasz Luba)"

"Here is the "big" set of staging and IIO driver patches for 5.12-rc1.

The IIO changes are:
- new drivers

- new iio driver features
with full details in the shortlog.
The staging driver patches are just a lot of tiny coding style
cleanups, along with some semi-larger hikey driver cleanups as those
are _almost_ good enough to get out of the staging tree, but will
probably have to wait until 5.13 to have happen.

Al root-caused a new warning from syzbot to the ttyprintk tty driver
returning a write count larger than the data the tty layer actually gave
it. Which confused the tty write code mightily, and with the new
iov_iter based code, caused a WARNING in iov_iter_revert().
syzbot correctly bisected the source of the new warning to commit
9bb48c82aced ("tty: implement write_iter"), but the oddity goes back
much further, it just didn't get caught by anything before.

"There are a lot of platforms that have not seen any interesting code
changes in the past five years or more.
I made a list and asked around which ones are no longer in use, and
received confirmation about six ARM platforms and the TI C6x
architecture that have all reached the end of their life upstream,
with no known users remaining:
- efm32 - added in 2011, first Cortex-M, no notable changes after 2013
- picoxcell - added in 2011, abandoned after 2012 acquisition
- prima2 - added in 20111, no notable changes since 2015
- tango - added in 2015, sporadic changes until 2017, but abandoned
- u300 - added in 2009, no notable changes since 2013
- zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x - added in 2011, but work stalled soon after that
A number of other platforms on the original list turned out to still
have users. In some cases there are out-of-tree patches and users that
plan to contribute them in the future, in other cases the code is
complete and works reliably"

Part of the device initialization aligns the rising edge of the output
clock to the internal 1 PPS clock. If the system APLL and DPLL is not
locked, then the alignment will fail and there will be a fixed offset
between the internal 1 PPS clock and the output clock.
After loading the device firmware, poll the system APLL and DPLL for
locked state prior to initialization, timing out after 2 seconds.

On cpu architectures w/o dma cache snooping, dma_unmap() is a

needs to invalidate cpu caches.

The buffers in the lan743x driver's receive ring are always 9K,
even when the largest packet that can be received (the mtu) is
much smaller. This performs particularly badly on cpu archs
without dma cache snooping (such as ARM): each received packet
results in a 9K dma_{map|unmap} operation, which is very expensive
because cpu caches need to be invalidated.
Careful measurement of the driver rx path on armv7 reveals that
the cpu spends the majority of its time waiting for cache
invalidation.
Optimize by keeping the rx ring buffer size as close as possible
to the mtu. This limits the amount of cache that requires
invalidation.
This optimization would normally force us to re-allocate all
ring buffers when the mtu is changed - a disruptive event,
because it can only happen when the network interface is down.
Remove the need to re-allocate all ring buffers by adding support
for multi-buffer frames. Now any combination of mtu and ring
buffer size will work. When the mtu changes from mtu1 to mtu2,
consumed buffers of size mtu1 are lazily replaced by newly
allocated buffers of size mtu2.
These optimizations double the rx performance on armv7.
Third parties report 3x rx speedup on armv8.

The following call path suggests that calling unregister_netdev on an
interface that is up will first bring it down.
enetc_pf_remove
-> unregister_netdev
-> unregister_netdevice_queue
-> unregister_netdevice_many
-> dev_close_many
-> __dev_close_many
-> enetc_close
-> enetc_stop
-> phylink_stop
However, enetc first destroys the phylink instance, then calls
unregister_netdev. This is already dissimilar to the setup (and error
path teardown path) from enetc_pf_probe, but more than that, it is buggy
because it is invalid to call phylink_stop after phylink_destroy.
So let's first unregister the netdev (and let the .ndo_stop events
consume themselves), then destroy the phylink instance, then free the
netdev.

Add basic support for MRP. The HW will just trap all MRP frames on the
ring ports to CPU and allow the SW to process them. In this way it is
possible to for this node to behave both as MRM and MRC.
Current limitations are:
- it doesn't support Interconnect roles.
- it supports only a single ring.
- the HW should be able to do forwarding of MRP Test frames so the SW
will not need to do this. So it would be able to have the role MRC
without SW support.

Normally, auto negotiation and reconnect should be automatically done by
the hardware. But there seems to be an issue where auto negotiation has
to be restarted manually. This happens because of link training and so
even though still connected to the partner the link never "comes back".
This needs an auto-negotiation restart.
Also, a change in xgbe-mdio is needed to get ethtool to recognize the
link down and get the link change message. This change is only
required in a backplane connection mode.

Device timestamp can be in real time mode (cycles to time translation is
offloaded into the Hardware). With real time mode, HW provides timestamp
which is already translated into nanoseconds.
With this mode, driver adjusts both the HW and timecounter (to keep
clock_info_page updated) using callbacks: adjfreq, adjtime and settime.
HW clock modifications are done via MTUTC access reg commands. Driver is
allowed to modify HW real time clock only if MCAM ptpcyc2realtime_modify
capability is set.
Add MTUTC set function to be used for configuring the HW real time
clock. Modify existing code to support both internal timer (with
conversion via timecounter_cyc2time() and real time (no conversions).
Align the signatures of the helpers converting from timestamp to
nanoseconds. With that, when allocating a queue assign the corresponding
callback with respect to the capability.
Adjust 1PPS timestamp calculation flows based on the timestamp mode.
Cyc2time offload brings two major advantages:
- Improve MTAE (Max Time Absolute Error) for HW TS by up to 160 ns over a
100% loaded CPU.
- Faster data-path timestamp to nanoseconds, as translation is
lock-less and done in HW.
On real time mode, timestamp format is 32 high bits of seconds and 32
low bits of nanoseconds. On some flows, driver shall convert this format
into nanoseconds wall-clock with REAL_TIME_TO_NS macro.
HW supports a single clock, and it is shared by all functions on a
device. In case real time clock is used, it is recommended to use
a single GM to all device's functions.

Quite embarrasingly, I managed to fool myself into thinking that the
flooding domain of sja1105 source ports is restricted by the forwarding
domain, which it isn't. Frames which match an FDB entry are forwarded
towards that entry's DESTPORTS restricted by REACH_PORT[SRC_PORT], while
frames that don't match any FDB entry are forwarded towards
FL_DOMAIN[SRC_PORT] or BC_DOMAIN[SRC_PORT].
This means we can't get away with doing the simple thing, and we must
manage the flooding domain ourselves such that it is restricted by the
forwarding domain. This new function must be called from the
.port_bridge_join and .port_bridge_leave methods too, not just from

We configure the minimum and maximum number of various types of IPA
resources in ipa_resource_config(). It iterates over resource types
in the configuration data and assigns resource limits to each
resource group for each type.
Unfortunately, we are repeatedly initializing the resource data for
the first type, rather than initializing each of the types whose
limits are specified.
Fix this bug.

Some internal PHY's have their events like link change reported by the
MAC interrupt. We have PHY_IGNORE_INTERRUPT to deal with this scenario.
I'm not too happy with this name. We don't ignore interrupts, typically
there is no interrupt exposed at a PHY level. So let's rename it to
PHY_MAC_INTERRUPT. This is in line with phy_mac_interrupt(), which is
called from the MAC interrupt handler to handle PHY events.

The work queue is used to queue reset requests like CHANGE-PARAM or
FAILOVER resets for the worker thread. When the adapter is being removed
the adapter state is set to VNIC_REMOVING and the work queue is flushed
so no new work is added. However the check for adapter being removed is
racy in that the adapter can go into REMOVING state just after we check
and we might end up adding work just as it is being flushed (or after).
The ->rwi_lock is already being used to serialize queue/dequeue work.
Extend its usage ensure there is no race when scheduling/flushing work.

shift every existing flag down into a contiguous assignment.
PHY_BCM_FLAGS_MODE_1000BX was only used internally for the BCM54616S

Hardware comes up with default max frame size set to 1518. When using it
with switch it results in actual Ethernet MTU 1492:
1518 - 14 (Ethernet header) - 4 (Broadcom's tag) - 4 (802.1q) - 4 (FCS)
Above means hardware in its default state can't handle standard Ethernet
traffic (MTU 1500).
Define maximum possible Ethernet overhead and always set MAC max frame
length accordingly. This change fixes handling Ethernet frames of length
1506 - 1514.

default
The sja1105 driver has a limitation, extensively described under
Documentation/networking/dsa/sja1105.rst and
Documentation/networking/devlink/sja1105.rst, which says that when the
ports are under a bridge with vlan_filtering=1, traffic to and from
the network stack is not possible, unless the driver-specific
best_effort_vlan_filtering devlink parameter is enabled.
For users, this creates a 'wtf' moment. They need to go to the
documentation and find about the existence of this property, then maybe
install devlink and set it to true.
Having best_effort_vlan_filtering enabled by the kernel by default
delays that 'wtf' moment (maybe up to the point that it never even
happens). The user doesn't need to care that the driver supports
addressing the ports individually by retagging VLAN IDs until he/she
needs to use more than 32 VLAN IDs (since there can be at most 32
retagging rules). Only then do they need to think whether they need the
full VLAN table, at the expense of no individual port addressing, or
not.
But the odds that an sja1105 user will need more than 32 VLANs
terminated by the CPU is probably low. And, if we were to follow the
principle that more advanced use cases should require more advanced
preparation steps, then it makes more sense for ping to 'just work'
while CPU termination of > 32 VLAN IDs to require a bit more forethought
and possibly a driver-specific devlink param.
So we should be able to safely change the default here, and make this
driver act just a little bit more sanely out of the box.

Smatch is confused by the fact that a 32-bit BIT(port) macro is passed
as argument to the ocelot_ifh_set_dest function and warns:
ocelot_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?
seville_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?
The destination port mask is copied into a 12-bit field of the packet,
starting at bit offset 67 and ending at 56.
So this DSA tagging protocol supports at most 12 bits, which is clearly
less than 32. Attempting to send to a port number > 12 will cause the
packing() call to truncate way before there will be 32-bit truncation
due to type promotion of the BIT(port) argument towards u64.
Therefore, smatch's fears that BIT(port) will do the wrong thing and
cause unexpected truncation for "port" values >= 32 are unfounded.
Nonetheless, let's silence the warning by explicitly passing an u64
value to ocelot_ifh_set_dest, such that the compiler does not need to do
a questionable type promotion.

instead of printing to the kernel log. Where the conversion would have
been lossy and things like VLAN ID could no longer be conveyed (due to
the lack of support for printf format specifier in netlink extack), I

For TX timestamping, we use the felix_txtstamp method which is common
with the regular (non-8021q) ocelot tagger. This method says that skb
deferral is needed, prepares a timestamp request ID, and puts a clone of
the skb in a queue waiting for the timestamp IRQ.
felix_txtstamp is called by dsa_skb_tx_timestamp() just before the
tagger's xmit method. In the tagger xmit, we divert the packets
classified by dsa_skb_tx_timestamp() as PTP towards the MMIO-based
injection registers, and we declare them as dead towards dsa_slave_xmit.
If not PTP, we proceed with normal tag_8021q stuff.
Then the timestamp IRQ fires, the clone queued up from felix_txtstamp is
matched to the TX timestamp retrieved from the switch's FIFO based on
the timestamp request ID, and the clone is delivered to the stack.
On RX, thanks to the VCAP IS2 rule that redirects the frames with an
EtherType for 1588 towards two destinations:
- the CPU port module (for MMIO based extraction) and
- if the "no XTR IRQ" workaround is in place, the dsa_8021q CPU port
the relevant data path processing starts in the ptp_classify_raw BPF
classifier installed by DSA in the RX data path (post tagger, which is
completely unaware that it saw a PTP packet).
This time we can't reuse the same implementation of .port_rxtstamp that
also works with the default ocelot tagger. That is because felix_rxtstamp
is given an skb with a freshly stripped DSA header, and it says "I don't
need deferral for its RX timestamp, it's right in it, let me show you";
and it just points to the header right behind skb->data, from where it
unpacks the timestamp and annotates the skb with it.
The same thing cannot happen with tag_ocelot_8021q, because for one
thing, the skb did not have an extraction frame header in the first
place, but a VLAN tag with no timestamp information. So the code paths
in felix_rxtstamp for the regular and 8021q tagger are completely
independent. With tag_8021q, the timestamp must come from the packet's
duplicate delivered to the CPU port module, but there is potentially
complex logic to be handled [ and prone to reordering ] if we were to
just start reading packets from the CPU port module, and try to match
them to the one we received over Ethernet and which needs an RX
timestamp. So we do something simple: we tell DSA "give me some time to
think" (we request skb deferral by returning false from .port_rxtstamp)
and we just drop the frame we got over Ethernet with no attempt to match
it to anything - we just treat it as a notification that there's data to
be processed from the CPU port module's queues. Then we proceed to read
the packets from those, one by one, which we deliver up the stack,
timestamped, using netif_rx - the same function that any driver would
use anyway if it needed RX timestamp deferral. So the assumption is that
we'll come across the PTP packet that triggered the CPU extraction
notification eventually, but we don't know when exactly. Thanks to the
VCAP IS2 trap/redirect rule and the exclusion of the CPU port module
from the flooding replicators, only PTP frames should be present in the
CPU port module's RX queues anyway.
There is just one conflict between the VCAP IS2 trapping rule and the
semantics of the BPF classifier. Namely, ptp_classify_raw() deems
general messages as non-timestampable, but still, those are trapped to
the CPU port module since they have an EtherType of ETH_P_1588. So, if
the "no XTR IRQ" workaround is in place, we need to run another BPF
classifier on the frames extracted over MMIO, to avoid duplicates being
sent to the stack (once over Ethernet, once over MMIO). It doesn't look
like it's possible to install VCAP IS2 rules based on keys extracted
from the 1588 frame headers.

Since the tag_8021q tagger is software-defined, it has no means by
itself for retrieving hardware timestamps of PTP event messages.
Because we do want to support PTP on ocelot even with tag_8021q, we need
to use the CPU port module for that. The RX timestamp is present in the
Extraction Frame Header. And because we can't use NPI mode which redirects
the CPU queues to an "external CPU" (meaning the ARM CPU running Linux),
then we need to poll the CPU port module through the MMIO registers to
retrieve TX and RX timestamps.
Sadly, on NXP LS1028A, the Felix switch was integrated into the SoC
without wiring the extraction IRQ line to the ARM GIC. So, if we want to
be notified of any PTP packets received on the CPU port module, we have
a problem.
There is a possible workaround, which is to use the Ethernet CPU port as
a notification channel that packets are available on the CPU port module
as well. When a PTP packet is received by the DSA tagger (without timestamp,
of course), we go to the CPU extraction queues, poll for it there, then
we drop the original Ethernet packet and masquerade the packet retrieved
over MMIO (plus the timestamp) as the original when we inject it up the
stack.
Create a quirk in struct felix is selected by the Felix driver (but not
by Seville, since that doesn't support PTP at all). We want to do this
such that the workaround is minimally invasive for future switches that
don't require this workaround.
The only traffic for which we need timestamps is PTP traffic, so add a
redirection rule to the CPU port module for this. Currently we only have
the need for PTP over L2, so redirection rules for UDP ports 319 and 320
are TBD for now.
Note that for the workaround of matching of PTP-over-Ethernet-port with
PTP-over-MMIO queues to work properly, both channels need to be
absolutely lossless. There are two parts to achieving that:
- We keep flow control enabled on the tag_8021q CPU port
- We put the DSA master interface in promiscuous mode, so it will never
drop a PTP frame (for the profiles we are interested in, these are
sent to the multicast MAC addresses of 01-80-c2-00-00-0e and
01-1b-19-00-00-00).

Since the felix DSA driver will need to poll the CPU port module for
extracted frames as well, let's create some common functions that read
an Extraction Frame Header, and then an skb, from a CPU extraction
group.
We abuse the struct ocelot_ops :: port_to_netdev function a little bit,
in order to retrieve the DSA port net_device or the ocelot switchdev
net_device based on the source port information from the Extraction
Frame Header, but it's all in the benefit of code simplification -
netdev_alloc_skb needs it. Originally, the port_to_netdev method was
intended for parsing act->dev from tc flower offload code.

The ocelot tagger is a hot mess currently, it relies on memory
initialized by the attached driver for basic frame transmission.
This is against all that DSA tagging protocols stand for, which is that
the transmission and reception of a DSA-tagged frame, the data path,
should be independent from the switch control path, because the tag
protocol is in principle hot-pluggable and reusable across switches
(even if in practice it wasn't until very recently). But if another
driver like dsa_loop wants to make use of tag_ocelot, it couldn't.
This was done to have common code between Felix and Ocelot, which have
one bit difference in the frame header format. Quoting from commit
67c2404922c2 ("net: dsa: felix: create a template for the DSA tags on
xmit"):
Other alternatives have been analyzed, such as:
- Create a separate tag_seville.c: too much code duplication for just 1
bit field difference.
- Create a separate DSA_TAG_PROTO_SEVILLE under tag_ocelot.c, just like
tag_brcm.c, which would have a separate .xmit function. Again, too
much code duplication for just 1 bit field difference.
- Allocate the template from the init function of the tag_ocelot.c
module, instead of from the driver: couldn't figure out a method of
accessing the correct port template corresponding to the correct
tagger in the .xmit function.
The really interesting part is that Seville should have had its own
tagging protocol defined - it is not compatible on the wire with Ocelot,
even for that single bit. In principle, a packet generated by
DSA_TAG_PROTO_OCELOT when booted on NXP LS1028A would look in a certain
way, but when booted on NXP T1040 it would look differently. The reverse
is also true: a packet generated by a Seville switch would be
interpreted incorrectly by Wireshark if it was told it was generated by
an Ocelot switch.
Actually things are a bit more nuanced. If we concentrate only on the
DSA tag, what I said above is true, but Ocelot/Seville also support an
optional DSA tag prefix, which can be short or long, and it is possible
to distinguish the two taggers based on an integer constant put in that
prefix. Nonetheless, creating a separate tagger is still justified,
since the tag prefix is optional, and without it, there is again no way
to distinguish.
Claiming backwards binary compatibility is a bit more tough, since I've
already changed the format of tag_ocelot once, in commit 5124197ce58b
("net: dsa: tag_ocelot: use a short prefix on both ingress and egress").
Therefore I am not very concerned with treating this as a bugfix and
backporting it to stable kernels (which would be another mess due to the
fact that there would be lots of conflicts with the other DSA_TAG_PROTO*
definitions). It's just simpler to say that the string values of the
taggers have ABI value starting with kernel 5.12, which will be when the
changing of tag protocol via /sys/class/net/<dsa-master>/dsa/tagging
goes live.

The Injection Frame Header and Extraction Frame Header that the switch
prepends to frames over the NPI port is also prepended to frames
delivered over the CPU port module's queues.
Let's unify the handling of the frame headers by making the ocelot
driver call some helpers exported by the DSA tagger. Among other things,
this allows us to get rid of the strange cpu_to_be32 when transmitting
the Injection Frame Header on ocelot, since the packing API uses
network byte order natively (when "quirks" is 0).
The comments above ocelot_gen_ifh talk about setting pop_cnt to 3, and
the cpu extraction queue mask to something, but the code doesn't do it,
so we don't do it either.

It appears that the intention of this snippet of code is to not exit
ocelot_xtr_irq_handler() while in the middle of extracting a frame.
The problem in extracting it word by word is that future extraction
attempts are really easy to get desynchronized, since the IRQ handler
assumes that the first 16 bytes are the IFH, which give further
information about the frame, such as frame length.
But during normal operation, "err" will not be 0, but 4, set from here:
for (i = 0; i < OCELOT_TAG_LEN / 4; i++) {
err = ocelot_rx_frame_word(ocelot, grp, true, &ifh[i]);
if (err != 4)
break;
}
if (err != 4)
break;
In that case, draining the extraction queue is a no-op. So explicitly
make this code execute only on negative err.

Populate the bnxt_mem_init structure with the proper offset returned

the old behavior of initializing every byte. Otherwise, we initialize

Currently, the driver calls memset() to set all relevant context memory
used by the chip to the initial value. This can take many milliseconds
with the potentially large number of context pages allocated for the
chip.
To make this faster, we only need to initialize the "context kind" field
of each block of context memory. This patch sets up the infrastructure
to do that with the bnxt_mem_init structure. In the next patch, we'll
add the logic to obtain the offset of the "context kind" from the
firmware. This patch is not changing the current behavior of calling

During some fatal firmware error conditions, the PCI config space
register 0x2e which normally contains the subsystem ID will become
0xffff. This register will revert back to the normal value after
the chip has completed core reset. If we detect this condition,
we can poll this config register immediately for the value to revert.
Because we use config read cycles to poll this register, there is no
possibility of Master Abort if we happen to read it during core reset.
This speeds up recovery significantly as we don't have to wait for the
conservative min_time before polling MMIO to see if the firmware has
come out of reset. As soon as this register changes value we can
proceed to re-initialize the device.

leds: rt8515: add V4L2_FLASH_LED_CLASS dependency
|
|
The leds-rt8515 driver can optionall use the v4l2 flash led class,
but it causes a link error when that class is in a loadable module
and the rt8515 driver itself is built-in:
ld.lld: error: undefined symbol: v4l2_flash_init
>>> referenced by leds-rt8515.c
>>> leds/flash/leds-rt8515.o:(rt8515_probe) in archive
drivers/built-in.a
Adding 'depends on V4L2_FLASH_LED_CLASS' in Kconfig would avoid that,
but it would make it impossible to use the driver without the
v4l2 support.
Add the same dependency that the other users of this class have
instead, which just prevents the broken configuration.

This driver is set up to use a clock mapping in the device tree if it is
present, but still work without one for backward compatibility. However,
if getting the clock returns -EPROBE_DEFER, then we need to abort and
return that error from our driver initialization so that the probe can
be retried later after the clock is set up.
Move clock initialization to earlier in the process so we do not waste as
much effort if the clock is not yet available. Switch to use
devm_clk_get_optional and abort initialization on any error reported.
Also enable the clock regardless of whether the controller is using an MDIO
bus, as the clock is required in any case.

The chip can configure unicast flooding, broadcast flooding and learning.
Learning is per port, while flooding is per {ingress, egress} port pair
and we need to configure the same value for all possible ingress ports
towards the requested one.
While multicast flooding is not officially supported, we can hack it by
using a feature of the second generation (P/Q/R/S) devices, which is that
FDB entries are maskable, and multicast addresses always have an odd
first octet. So by putting a match-all for 00:01:00:00:00:00 addr and
00:01:00:00:00:00 mask at the end of the FDB, we make sure that it is
always checked last, and does not take precedence in front of any other
MDB. So it behaves effectively as an unknown multicast entry.
For the first generation switches, this feature is not available, so
unknown multicast will always be treated the same as unknown unicast.
So the only thing we can do is request the user to offload the settings
for these 2 flags in tandem, i.e.
ip link set swp2 type bridge_slave flood off
Error: sja1105: This chip cannot configure multicast flooding independently of unicast.
ip link set swp2 type bridge_slave flood off mcast_flood off
ip link set swp2 type bridge_slave mcast_flood on
Error: sja1105: This chip cannot configure multicast flooding independently of unicast.

We should not be unconditionally enabling address learning, since doing
that is actively detrimential when a port is standalone and not offloading
a bridge. Namely, if a port in the switch is standalone and others are
offloading the bridge, then we could enter a situation where we learn an
address towards the standalone port, but the bridged ports could not
forward the packet there, because the CPU is the only path between the
standalone and the bridged ports. The solution of course is to not
enable address learning unless the bridge asks for it.
We need to set up the initial port flags for no learning and flooding
everything, and also when the port joins and leaves the bridge.
The flood configuration was already configured ok for standalone mode
in ocelot_init, we just need to disable learning in ocelot_init_port.

There are multiple ways in which a PORT_BRIDGE_FLAGS attribute can be
expressed by the bridge through switchdev, and not all of them can be
emulated by DSA mid-layer API at the same time.
One possible configuration is when the bridge offloads the port flags
using a mask that has a single bit set - therefore only one feature
should change. However, DSA currently groups together unicast and
multicast flooding in the .port_egress_floods method, which limits our
options when we try to add support for turning off broadcast flooding:
do we extend .port_egress_floods with a third parameter which b53 and
mv88e6xxx will ignore? But that means that the DSA layer, which
currently implements the PRE_BRIDGE_FLAGS attribute all by itself, will
see that .port_egress_floods is implemented, and will report that all 3
types of flooding are supported - not necessarily true.
Another configuration is when the user specifies more than one flag at
the same time, in the same netlink message. If we were to create one
individual function per offloadable bridge port flag, we would limit the
expressiveness of the switch driver of refusing certain combinations of
flag values. For example, a switch may not have an explicit knob for
flooding of unknown multicast, just for flooding in general. In that
case, the only correct thing to do is to allow changes to BR_FLOOD and
BR_MCAST_FLOOD in tandem, and never allow mismatched values. But having
a separate .port_set_unicast_flood and .port_set_multicast_flood would
not allow the driver to possibly reject that.
Also, DSA doesn't consider it necessary to inform the driver that a
SWITCHDEV_ATTR_ID_BRIDGE_MROUTER attribute was offloaded, because it
just calls .port_egress_floods for the CPU port. When we'll add support
for the plain SWITCHDEV_ATTR_ID_PORT_MROUTER, that will become a real
problem because the flood settings will need to be held statefully in
the DSA middle layer, otherwise changing the mrouter port attribute will
impact the flooding attribute. And that's _assuming_ that the underlying
hardware doesn't have anything else to do when a multicast router
attaches to a port than flood unknown traffic to it. If it does, there
will need to be a dedicated .port_set_mrouter anyway.
So we need to let the DSA drivers see the exact form that the bridge
passes this switchdev attribute in, otherwise we are standing in the
way. Therefore we also need to use this form of language when
communicating to the driver that it needs to configure its initial
(before bridge join) and final (after bridge leave) port flags.
The b53 and mv88e6xxx drivers are converted to the passthrough API and
their implementation of .port_egress_floods is split into two: a
function that configures unicast flooding and another for multicast.
The mv88e6xxx implementation is quite hairy, and it turns out that
the implementations of unknown unicast flooding are actually the same
for 6185 and for 6352:
behind the confusing names actually lie two individual bits:
NO_UNKNOWN_MC -> FLOOD_UC = 0x4 = BIT(2)
NO_UNKNOWN_UC -> FLOOD_MC = 0x8 = BIT(3)
so there was no reason to entangle them in the first place.
Whereas the 6185 writes to MV88E6185_PORT_CTL0_FORWARD_UNKNOWN of
PORT_CTL0, which has the exact same bit index. I have left the
implementations separate though, for the only reason that the names are
different enough to confuse me, since I am not able to double-check with
a user manual. The multicast flooding setting for 6185 is in a different
register than for 6352 though.

This switchdev attribute offers a counterproductive API for a driver
writer, because although br_switchdev_set_port_flag gets passed a
"flags" and a "mask", those are passed piecemeal to the driver, so while
the PRE_BRIDGE_FLAGS listener knows what changed because it has the
"mask", the BRIDGE_FLAGS listener doesn't, because it only has the final
value. But certain drivers can offload only certain combinations of
settings, like for example they cannot change unicast flooding
independently of multicast flooding - they must be both on or both off.
The way the information is passed to switchdev makes drivers not
expressive enough, and unable to reject this request ahead of time, in
the PRE_BRIDGE_FLAGS notifier, so they are forced to reject it during
the deferred BRIDGE_FLAGS attribute, where the rejection is currently
ignored.
This patch also changes drivers to make use of the "mask" field for edge
detection when possible.

In ipa_cmd_register_write_valid() we verify that values we will
supply to a REGISTER_WRITE IPA immediate command will fit in
the fields that need to hold them. This patch fixes some issues
in that function and ipa_cmd_register_write_offset_valid().
The dev_err() call in ipa_cmd_register_write_offset_valid() has
some printf format errors:
- The name of the register (corresponding to the string format
specifier) was not supplied.
- The IPA base offset and offset need to be supplied separately to
match the other format specifiers.
Also make the ~0 constant used there to compute the maximum
supported offset value explicitly unsigned.
There are two other issues in ipa_cmd_register_write_valid():
- There's no need to check the hash flush register for platforms
(like IPA v4.2) that do not support hashed tables
- The highest possible endpoint number, whose status register
offset is computed, is COUNT - 1, not COUNT.
Fix these problems, and add some additional commentary.

This patch actually fixes a bug, though it doesn't affect the two
platforms supported currently. The fix implements GSI memory
pointers a bit differently.
For IPA version 4.5 and above, the address space for almost all GSI
registers is adjusted downward by a fixed amount. This is currently
handled by adjusting the I/O virtual address pointer after it has
been mapped. The bug is that the pointer is not "de-adjusted" as it
should be when it's unmapped.
This patch fixes that error, but it does so by maintaining one "raw"
pointer for the mapped memory range. This is assigned when the
memory is mapped and used to unmap the memory. This pointer is also
used to access the two registers that do *not* sit in the "adjusted"
memory space.
Rather than adjusting *that* pointer, we maintain a separate pointer
that's an adjusted copy of the "raw" pointer, and that is used for
most GSI register accesses.
