2004/05/07 17:24:44-04:00 len.brown@intel.com # [ACPI] ACPICA 20040427 from Bob Moore # # Completed a major overhaul of the GPE handling within ACPI CA. # There are now three types of GPEs: # wake-only; runtime-only; combination wake/run. # # The only GPEs allowed to be combination wake/run are for # button-style devices such as a control-method power button, # control-method sleep button, or a notebook lid switch. # GPEs that have an _Lxx or _Exx method and are not referenced # by any _PRW methods are marked for "runtime" and hardware enabled. # # Any GPE that is referenced by a _PRW method is marked for "wake" # (and disabled at runtime). However, at sleep time, only those # GPEs that have been specifically enabled for wake via the # acpi_enable_gpe() interface will actually be hardware enabled. # # A new external interface has been added, acpi_set_gpe_type() # that is meant to be used by device drivers to force a GPE # to a particular type. It will be especially useful for the # drivers for the button devices mentioned above. # # Completed restructuring of the ACPI CA initialization sequence # so that default operation region handlers are installed # before GPEs are initialized and the _PRW methods are executed. # This will prevent errors when the _PRW methods attempt to # access system memory or I/O space. # # GPE enable/disable no longer reads the GPE enable register. # We now keep the enable info for runtime and wake separate # and in the GPE_EVENT_INFO. We thus no longer depend on # the hardware to maintain these bits. # # Always clear the wake status and fixed/GPE status bits # before sleep, even for state S5. # # Improved the AML debugger output for displaying the # GPE blocks and their current status. # # Added new strings for the _OSI method, of the form # "Windows 2001 SPx" where x = 0,1,2,3,4. # # Fixed a problem where the physical address was incorrectly # calculated when the Load() operator was used to directly # load from an Operation Region (vs. loading from a Field object.) # Also added check for minimum table length for this case. # # Fix for multiple mutex acquisition. Restore original thread # SyncLevel on mutex release. # # Added ACPI_VALID_SXDS flag to the acpi_get_object_info interface # for consistency with the other fields returned. # # Shrunk the ACPI_GPE_EVENT_INFO structure by 40%. # There is one such structure for each GPE in the system, # so the size of this structure is important. # # CPU stack requirement reduction: # Cleaned up the method execution and object evaluation paths # so that now a parameter structure is passed, instead of copying # the various method parameters over and over again. # # In evregion.c: # Correctly exit and reenter the interpreter region if and only # if dispatching an operation region request to a user-installed # handler. Do not exit/reenter when dispatching to a default # handler (e.g., default system memory or I/O handlers) # # include/acpi/actypes.h # 2004/05/07 13:10:42-04:00 len.brown@intel.com +46 -27 # ACPICA 20040427 # # include/acpi/actbl.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +16 -13 # ACPICA 20040427 # # include/acpi/acstruct.h # 2004/05/07 13:10:42-04:00 len.brown@intel.com +21 -2 # ACPICA 20040427 # # include/acpi/acpixf.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +8 -2 # ACPICA 20040427 # # include/acpi/acparser.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +1 -3 # ACPICA 20040427 # # include/acpi/acobject.h # 2004/05/07 13:10:42-04:00 len.brown@intel.com +7 -6 # ACPICA 20040427 # # include/acpi/acnamesp.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +5 -13 # ACPICA 20040427 # # include/acpi/aclocal.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +25 -14 # ACPICA 20040427 # # include/acpi/achware.h # 2004/05/07 13:10:42-04:00 len.brown@intel.com +11 -10 # ACPICA 20040427 # # include/acpi/acglobal.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +1 -0 # ACPICA 20040427 # # include/acpi/acexcep.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +4 -2 # ACPICA 20040427 # # include/acpi/acevents.h # 2004/05/07 13:10:42-04:00 len.brown@intel.com +48 -3 # ACPICA 20040427 # # include/acpi/acdispat.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +1 -2 # ACPICA 20040427 # # include/acpi/acconfig.h # 2004/05/07 13:10:43-04:00 len.brown@intel.com +2 -2 # ACPICA 20040427 # # drivers/acpi/utilities/utxface.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +26 -15 # ACPICA 20040427 # # drivers/acpi/utilities/utglobal.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +35 -21 # ACPICA 20040427 # # drivers/acpi/utilities/uteval.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +11 -7 # ACPICA 20040427 # # drivers/acpi/resources/rsutils.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +6 -1 # ACPICA 20040427 # # drivers/acpi/parser/psxface.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +27 -25 # ACPICA 20040427 # # drivers/acpi/namespace/nsxfname.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +2 -2 # ACPICA 20040427 # # drivers/acpi/namespace/nsxfeval.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +28 -24 # ACPICA 20040427 # # drivers/acpi/namespace/nsparse.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +3 -2 # ACPICA 20040427 # # drivers/acpi/namespace/nsinit.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +17 -14 # ACPICA 20040427 # # drivers/acpi/namespace/nseval.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +32 -58 # ACPICA 20040427 # # drivers/acpi/namespace/nsaccess.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +1 -1 # ACPICA 20040427 # # drivers/acpi/hardware/hwsleep.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +36 -16 # ACPICA 20040427 # # drivers/acpi/hardware/hwregs.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +17 -14 # ACPICA 20040427 # # drivers/acpi/hardware/hwgpe.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +92 -212 # ACPICA 20040427 # # drivers/acpi/executer/exoparg2.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +33 -3 # ACPICA 20040427 # # drivers/acpi/executer/exmutex.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +25 -21 # ACPICA 20040427 # # drivers/acpi/executer/exconfig.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +35 -12 # ACPICA 20040427 # # drivers/acpi/events/evxfregn.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +5 -195 # ACPICA 20040427 # # drivers/acpi/events/evxfevnt.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +101 -75 # ACPICA 20040427 # # drivers/acpi/events/evxface.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +58 -25 # ACPICA 20040427 # # drivers/acpi/events/evregion.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +346 -27 # ACPICA 20040427 # # drivers/acpi/events/evmisc.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +4 -0 # ACPICA 20040427 # # drivers/acpi/events/evgpeblk.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +104 -46 # ACPICA 20040427 # # drivers/acpi/events/evgpe.c # 2004/05/07 13:10:45-04:00 len.brown@intel.com +343 -25 # ACPICA 20040427 # # drivers/acpi/events/evevent.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +6 -6 # ACPICA 20040427 # # drivers/acpi/dispatcher/dswstate.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +13 -5 # ACPICA 20040427 # # drivers/acpi/dispatcher/dsopcode.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +2 -2 # ACPICA 20040427 # # drivers/acpi/dispatcher/dsmethod.c # 2004/05/07 13:10:46-04:00 len.brown@intel.com +10 -6 # ACPICA 20040427 # # ChangeSet # 2004/05/07 17:21:19-04:00 len.brown@intel.com # [ACPI] ACPICA 20040402 from Bob Moore # # Fixed an interpreter problem where an indirect store through an # ArgX parameter was incorrectly applying the "implicit conversion # rules" during the store. From the ACPI specification: "If the # target is a method local or argument (LocalX or ArgX), no # conversion is performed and the result is stored directly to the # target". The new behavior is to disable implicit conversion # during ALL stores to an ArgX. # # Changed the behavior of the _PRW method scan to ignore any and # all errors returned by a given _PRW. This prevents the scan from # aborting from the failure of any single _PRW. # # Moved the runtime configuration parameters from the global init # procedure to static variables in acglobal.h. This will allow the # host to override the default values easily. # # include/acpi/acinterp.h # 2004/05/07 13:11:48-04:00 len.brown@intel.com +4 -1 # ACPICA 20040402 # # include/acpi/acglobal.h # 2004/05/07 13:11:49-04:00 len.brown@intel.com +29 -7 # ACPICA 20040402 # # include/acpi/acdisasm.h # 2004/05/07 13:11:49-04:00 len.brown@intel.com +15 -0 # ACPICA 20040402 # # include/acpi/acconfig.h # 2004/05/07 13:11:49-04:00 len.brown@intel.com +1 -1 # ACPICA 20040402 # # drivers/acpi/utilities/utglobal.c # 2004/05/07 13:11:52-04:00 len.brown@intel.com +16 -10 # ACPICA 20040402 # # drivers/acpi/executer/exstore.c # 2004/05/07 13:11:52-04:00 len.brown@intel.com +14 -3 # ACPICA 20040402 # # drivers/acpi/executer/exfldio.c # 2004/05/07 13:11:52-04:00 len.brown@intel.com +1 -1 # ACPICA 20040402 # # drivers/acpi/events/evmisc.c # 2004/05/07 13:11:51-04:00 len.brown@intel.com +1 -1 # ACPICA 20040402 # # drivers/acpi/events/evgpeblk.c # 2004/05/07 13:11:51-04:00 len.brown@intel.com +4 -6 # ACPICA 20040402 # # drivers/acpi/dispatcher/dswload.c # 2004/05/07 13:11:51-04:00 len.brown@intel.com +22 -0 # ACPICA 20040402 # # drivers/acpi/dispatcher/dsmthdat.c # 2004/05/07 13:11:51-04:00 len.brown@intel.com +5 -3 # ACPICA 20040402 # # ChangeSet # 2004/05/03 12:31:49-04:00 len.brown@intel.com # Cset exclude: torvalds@evo.osdl.org|ChangeSet|20040401021818|60003 # # drivers/acpi/utilities/utglobal.c # 2004/05/03 12:31:41-04:00 len.brown@intel.com +0 -0 # Exclude # # drivers/acpi/osl.c # 2004/05/03 12:31:41-04:00 len.brown@intel.com +0 -0 # Exclude # diff -Nru a/drivers/acpi/Makefile b/drivers/acpi/Makefile --- a/drivers/acpi/Makefile 2004-07-13 12:25:18 -07:00 +++ b/drivers/acpi/Makefile 2004-07-13 12:25:18 -07:00 @@ -47,4 +47,4 @@ obj-$(CONFIG_ACPI_NUMA) += numa.o obj-$(CONFIG_ACPI_ASUS) += asus_acpi.o obj-$(CONFIG_ACPI_TOSHIBA) += toshiba_acpi.o -obj-$(CONFIG_ACPI_BUS) += scan.o +obj-$(CONFIG_ACPI_BUS) += scan.o motherboard.o diff -Nru a/drivers/acpi/dispatcher/dsmethod.c b/drivers/acpi/dispatcher/dsmethod.c --- a/drivers/acpi/dispatcher/dsmethod.c 2004-07-13 12:25:18 -07:00 +++ b/drivers/acpi/dispatcher/dsmethod.c 2004-07-13 12:25:18 -07:00 @@ -145,8 +145,9 @@ return_ACPI_STATUS (AE_NO_MEMORY);
