我6.1内核之前有很严重的断流问题(大概不到十分钟就断一次),后来进内核开了rtw89驱动之后有很大改善,不过偶尔还是会断

RE: Try to Use Archlinux Arm
@plumlis I tried. Seems that the file from linux-firmware package in archlinux arm is the same as file from this site.

Try to Use Archlinux Arm
Hello, I' m trying to use archlinux arm on pi cm5 laptop v20. The kernel I use is from github repo of cool-pi offcial, both 5.10 and 6.1 have been tried. In addition, I need to regenerate initrd.img by myself using dracut. I simply copied uboot from ubuntu img.
Both kernel can boot into system, but issues exist:
When booting from 5.10, I need to build mesa with panfork support from aur, and then I can use hardware acceleration in X11. However, entering plasma wayland will cause a black screen, and I can't input anything except poweroff.
If using 6.1, version of mesa from archlinux arm is 24.1.4 and linux-firmware package contains gpu firmware, which is at /lib/firmware/arm/mali/arch10.8/mali_csffw.bin. However I can't use any of hardware acceleration. Here is the dmesg:sudo dmesg | grep gpu [ 8.185337] vdd_gpu_s0: supplied by vcc5v0_sys [ 8.186427] vdd_gpu_s0: 550 <--> 950 mV at 750 mV, enabled [ 10.448271] I : [File] : drivers/gpu/arm/mali400/mali/linux/mali_kernel_linux.c; [Line] : 407; [Func] : mali_module_init(); svn_rev_string_from_arm of this mali_ko is '', rk_ko_ver is '5', built at '04:36:34', on 'Jul 23 2024'.

It's certain that file /lib/firmware/arm/mali/arch10.8/mali_csffw.bin exists. I have to use llvmpipe.
And sound system seems not working on kernel 6.1.
