Try to Use Archlinux Arm

prcups

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:

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.

Have you tried this firmware for 6.1?

prcups

@plumlis I tried. Seems that the file from linux-firmware package in archlinux arm is the same as file from this site.

plumlis

@prcups It seems same to me while I trying to make Fedora with panfrost.

About sound issue, Try to check alsamixer and unmute "left headphone mix" or "right headphone mix " something like that.

This works to me with kernel 6.1 under ubuntu.

This bin file path needs to be modified.

@prcups
Panthor needs to be loaded in KO mode.

@prcups try using this kernel its the rkr3 latest from rockchip
https://repo.bredos.org/repo/BredOS/aarch64/linux-rockchip-rkr3-6.1.75-8-aarch64.pkg.tar.zst
https://repo.bredos.org/repo/BredOS/aarch64/linux-rockchip-rkr3-headers-6.1.75-8-aarch64.pkg.tar.zst
https://repo.bredos.org/repo/BredOS/aarch64/mali-G610-firmware-rkr4-20240204-3-aarch64.pkg.tar.zst

then fix the kernel in extlinux.conf and enable the overlay

    kernel /vmlinuz-linux-rockchip-rkr3
    initrd /initramfs-linux-rockchip-rkr3.img
    fdtoverlays /dtbs/rockchip/overlay/rockchip-rk3588-panthor-gpu.dtbo

貌似是arch带的编译器版本太高了
用老编译器编的内核可以正常使用panthor
