And some of the devices run with more than one firmware +file. Basically, a "normal" firmware is necessary to be downloaded to +the device. +And another is called "wowlan" firmware, it should be loaded when a +device is going to suspend. Which means driver will "re-download/swap" +the firmware image. The wowlan firmware contains wake up functions that +can recognize specific events and send a wake up signal to device if +needed, and the system will resume to running state. During resume, +driver will then swap the normal firmware back, return to running state. + +If any distros or platforms do not require wowlan feature, they can +_only_ pick the normal firmware. And everything still works fine, +except that the device cannot be waken from the wireless NICs. + +Currently supported devices with corresponding firmwares: + +RTL8822BE + rtw8822b_fw.bin + +RTL8822CE + rtw8822c_fw.bin + rtw8822c_wow_fw.bin + |
