Hi All,
Xorg doesn’t start anymore after the commit tty: vt: use _IO() to define ioctl numbers.
Error message:
xf86OpenConsole: Switching VT failed.
I tested it with QEMU with virtio-gpu-pci and VGA,vgamem_mb=256 with some Linux distributions today.
I bisected today.
tty: vt: use _IO() to define ioctl numbers is the first bad commit (f1180ca37abe3d117e4a19be12142fe722612a7c)
I was able to revert the first bad commit.
After a new compiling, Xorg works again.
Please check the first bad commit.

Thanks,
