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:

Attempting to regzbot this.

Thx, I already had an eye on this, but thought tracking would not be
needed, as Greg (now CCed) wanted to revert 8c467f3300591a ("VT: Use
macros to define ioctls") two days ago:
https://lore.kernel.org/all/2024052901-police-trash-e9f9@gregkh/ (local)

But that commit is not yet in -next afaics. :-/

/me meanwhile wonders if it would be wise to fix this before -rc2

Ciao, Thorsten
