Hi All,

Here is the RC6 of kernel 6.16 for X1000 and e5500 machines (X5000/20, X5000/40, Mirari, and QEMU VMs).

Download and further information: github.com



The kernel error messages are gone.

Please test the kernels.

Thanks,
Christian

Hi All,

I compiled the alpha2 of kernel 6.17 with the first PowerPC updates 6.17-1 yesterday.

Unfortunately Xorg doesn’t start anymore.

Error message:

Code: Select all

xf86OpenConsole: Switching VT failed.

I tested it with QEMU with virtio-gpu-pci and VGA,vgamem_mb=256 with some Linux distributions yesterday.

I reported this issue to the kernel developers yesterday.

Link: Switching VT failed

Please test the kernels,

Christian

    tty: vt: use _IO() to define ioctl numbers

    _IO*() is the proper way of defining ioctl numbers. All these vt numbers
    were synthetically built up the same way the _IO() macro does.

    So instead of implicit hex numbers, use _IO() properly.

    To not change the pre-existing numbers, use only _IO() (and not _IOR()
    or _IOW()). The latter would change the numbers indeed.

    Objdump of vt_ioctl.o reveals no difference with this patch.

    Again, VT_GETCONSIZECSRPOS already uses _IOR(), so everything is paved
    for this patch.

I was able to revert the first bad commit.

Code: Select all

git revert f1180ca37abe3d117e4a19be12142fe722612a7c

Output:

Revert "tty: vt: use _IO() to define ioctl numbers"

This reverts commit f1180ca37abe3d117e4a19be12142fe722612a7c.

After a new compiling, Xorg works again.

I created a patch for reverting the bad commit.
