2023-12-01wifi: rtw89: mac: check queue empty according to chip genZong-Zhe Yang
This function, currently called by WoWLAN flow, polls until specific HW queues are empty. The polling bit definitions are not totally the same between WiFi 6 and 7 chips. In addition, the check conditions are also a little different. So, we differentiate the implementations according to chip gen.

Newer FW re-design SER (syetem error recovery) L1 (level 1) flow. New L1 flow will expect two extra states before original L1 flow. * Before: fw --- M1 --> driver fw <-- M2 --- driver fw --- M3 --> driver fw <-- M4 --- driver fw --- M5 --> driver * After: fw --- pre-M0 --> driver fw <-- post-M0 --- driver fw --- M1 --> driver fw <-- M2 --- driver fw --- M3 --> driver fw <-- M4 --- driver fw --- M5 --> driver Then before M1, FW gets one more interval to deal with things that FW should have handled well. To consider backward/forward compatibility, FW and driver won't change flow from M1 to M5. (only except that halt trigger control will change a little bit.) So, there will be two differnt starting points of SER L1. * old FW: SER L1 starts from M1 * new FW: SER L1 starts from pre-M0 Then, driver adds the new SER L1 entry and also keep the original one instead of changing it.

RXI300 is a HW design to maintain stuffs across BUS, e.g. AXI, AHB, APB. It will feedback an error when host does an invalid BUS operation. For example, * BUS master request without power/clock on. * host reads/writes/accesses an invalid address. They might lead to problems such as BUS timeout, platform hang, etc. So, once if RXI300 feedback an error, it notifies that driver need a L2 SER (system error recovery) to reset things.

2022-11-01wifi: rtw89: add function to adjust and restore PLE quotaChih-Kang Chang
PLE RX quota, which is the setting of RX buffer, is needed to be adjusted dynamically for WoWLAN mode, and restored when back to normal mode. The action is not needed for rtw8852c chip.

2022-11-01wifi: rtw89: move enable_cpu/disable_cpu into fw_downloadChih-Kang Chang
For WoWLAN mode, we need to download WoWLAN firmware by calling fw_download(). Another, to disable/enable WiFi CPU is needed before calling fw_download. Since Firmware runs on WiFi CPU, it is intuitive to combine enable_cpu/disable_cpu functions into fw_download.

2022-10-12wifi: rtw89: 8852b: add power on/off functionsPing-Ke Shih
We need power on function to enable hardware circuits of MAC/BB/RF, and then download firmware and load PHY parameters. After more settings, it starts to work. When it enters idle, use power off function to have the lowest power consumption.

2022-10-05wifi: rtw89: add to dump TX FIFO 0/1 for 8852CPing-Ke Shih
MAC maintains TX FIFO to transmit packets with meta data to BB layer. To debug abnormal transmission, we need to dump the content to dig problem. Since FIFO of 8852C locates on different address with different size and need additional switch to enable read operation, this patch adds the changes accordingly.

2022-09-19wifi: rtw89: support SER L1 simulationZong-Zhe Yang
SER (system error recovery) can deal with different crash types by different levels of processes. Previous FW crash simulation triggers a CPU exception which is one kind of SER L2 type. It can verify SER L2 flow which includes HW/FW restart. Now, we want to increase crash simulation types. A debug function is added to trigger control error in purpose for SER L1 simulation/verification. And, debugfs fw_crash is extended to accept different parameters. echo 1 > fw_crash: simulate CPU exception as before (keep 1 for compatibility with previous) It will be catched and handled by SER L2. (this requires HW/FW restart) echo 2 > fw_crash: simulate control error It will be catched and handled by SER L1. (driver and FW cooperate to recover this) Besides, in order to apply to the above two cases, rename RTW89_FLAG_RESTART_TRIGGER to RTW89_FLAG_CRASH_SIMULATING and adjust where SER flow clears this bit for both L1 and L2.
