wifi: rtw89: mac: refine SER setting during WiFi CPU power onDon't enable firmware debug mode to prevent SER flow stuck due to failto reset payload buffer, and clear HALT_C2H_INT to avoid handlingunexpected interrupt at beginning.Signed-off-by: Ping-Ke Shih <pkshih@realtek.com>Signed-off-by: Kalle Valo <kvalo@kernel.org>Link: https://lore.kernel.org/r/20231204080751.15354-6-pkshih@realtek.com, Larry Finger
wifi: rtw89: 8922a: dump MAC registers when SER occursTo diagnose the reason why firmware or hardware get abnormal, add to dumpMAC registers related to counters and interrupt masks. With these values,people can classify problems and check if registers values are unexpected,and then correct them. However, it could possible false alarm becausefirmware triggers this SER event by wrong conditions that we shouldcorrect it at firmware or register settings.In field, SER might happen under special conditions, and very hard tohappen again, so dump lots of registers to provide rich information tocatch the problem.Signed-off-by: Chia-Yuan Li <leo.li@realtek.com>Signed-off-by: Zong-Zhe Yang <kevin_yang@realtek.com>Signed-off-by: Ping-Ke Shih <pkshih@realtek.com>Signed-off-by: Kalle Valo <kvalo@kernel.org>Link: https://lore.kernel.org/r/20231204080751.15354-5-pkshih@realtek.com, Larry Finger
wifi: rtw89: 8922a: add SER IMR tablesTo activate SER (system error recovery) in firmware, we have to configureIMR to trigger interrupts, and then SER can check registers to know if itneed to reset hardware or notify driver to re-configure whole settings.Signed-off-by: Ping-Ke Shih <pkshih@realtek.com>Signed-off-by: Kalle Valo <kvalo@kernel.org>Link: https://lore.kernel.org/r/20231204080751.15354-4-pkshih@realtek.com, Larry Finger

GitHub – lwfinger/rtw89: Driver for Realtek 8852AE, an 802.11ax device

You will need to install “make”, “gcc”, “kernel headers”, “kernel build essentials”, and “git”. You can install them with the following command, on Ubuntu:

sudo apt-get update
sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git

If any of the packages above are not found check if your distro installs them like that.

Installation

Contents

For all distros:

git clone https://github.com/lwfinger/rtw89.git -b v5
cd rtw89
make
sudo make install

How to disable/enable a Kernel module

sudo modprobe -r rtw89pci         #This unloads the module
sudo modprobe rtw89pci            #This loads the module

Problem with recovery after sleep or hibernation

Some BIOSs have trouble changing power state from D3hot to D0. If you have this problem, then

sudo cp suspend_rtw89 /usr/lib/systemd/system-sleep/.

That script will unload the driver before sleep or hibernation, and reload it following resumption.

Option configuration

If it turns out that your system needs one of the configuration options, then do the following:

sudo nano /etc/modprobe.d/<dev_name>.conf

There, enter the line below:

options <device_name> <<driver_option_name>>=<value>

The available options for rtw89pci are disable_clkreq, disable_aspm, and disable_aspm The available options for rtw89core are debug_mask, and disable_ps_mode

Normally, none of these will be needed.

When your kernel changes, then you need to do the following:

cd ~/rtw89
git pull
make
sudo make install

Remember, this MUST be done whenever you get a new kernel – no exceptions.
