Hi All,

Xorg doesn't start anymore since the RC1 of kernel 6.10. We tested it
with the VirtIO GPU and with some Radeon cards.

Another error message: Failed to start Setup Virtual Console.

Maybe this is the issue: + CONFIG_ARCH_HAS_KERNEL_FPU_SUPPORT=y

Tested with FSL P5040, FSL P5020, and PASEMI boards.

Could you please test Xorg on your PowerPC machines?

Thanks,
Christian

I tested the RC1 in a virtual e5500 QEMU PowerPC machine with Bochs VGA
(-device VGA,vgamem_mb=256) and Xorg doesn't start either.

Error message: xf86OpenConsole: KDSETMODE KD_GRAPHICS failed
Inappropriate ioctl for device.

That is presumably because of this:

Hello Michael,

Many thanks for the hint! :-)

I was able to revert this commit and Xorg works again. We tested it with 
a Radeon and a VirtIO-GPU.

@Skateman
I reduced the uImage. Please test it. Link:

Have a nice weekend,
