Anyway. I manually add few tcz which are not yet in TC12 (gdk-pixbuf2.tcz, gamin.tcz) and firefox is running.
With this kernel version 5.10.3, for my CPU = AMD A6-6310 APU with AMD Radeon R4 Graphics, (core GCN 1.x or 2x?)
Is anything else that I can do to have amdpgu instead of radeon as video card driver?
because unfortunately radeon is detected/loaded first and not amdgpu.
tc@box:~$ lsmod | grep radeon
radeon 991232 0
drm_kms_helper 114688 1 radeon
ttm 53248 1 radeon
drm 286720 3 radeon,drm_kms_helper,ttm
backlight 12288 3 radeon,drm,video

but from dmesgLinux version 5.10.3-tinycore64 (root@box) (gcc (GCC) 10.2.0, GNU ld (GNU Binutils) 2.35.1) #2021 SMP Mon Dec 28 16:17:51 UTC 2020

..
[drm] radeon kernel modesetting enabled.
radeon 0000:00:01.0: CIK support disabled by module param
no MTRR for c0000000,1000000 found <-- is my UEFI buggy?
EDIT: even after I did oot@box:/home/tc# modprobe amdgpu
root@box:/home/tc# modprobe -r radeon
root@box:/home/tc# lsmod | grep radeon
root@box:/home/tc# lsmod | grep amdgpu
amdgpu 3342336 0

then Exit to console, and again startx, I have VESA not amdgpu driver (because Xorg is compiled with radeon in mind, not with amdgpu)
