git bisect start
git bisect good 887f3ceb51cd
git bisect bad 56bec2f9d4d0
git bisect good -- Xorg restarts again and again but we are looking for the first bad commit that
stops the boot after loading the dtb and uImage.
git bisect good -- Xorg restarts again and again.
git bisect good -- Xorg restarts again and again.
git bisect good -- Xorg restarts again and again.

56bec2f9d4d05675cada96772a8a93010f4d82bf is the first bad commit

powerpc/mm/64s: Add _PAGE_KERNEL_ROX
In the past we had a fallback definition for _PAGE_KERNEL_ROX, but we
removed that in commit d82fd29c5a8c ("powerpc/mm: Distribute platform
specific PAGE and PMD flags and definitions") and added definitions
for each MMU family.
However we missed adding a definition for 64s, which was not really a
bug because it's currently not used.
But we'd like to use PAGE_KERNEL_ROX in a future patch so add a
definition now.

Xorg works after compiling with the cherry-pick of 525642624783.
Hi All,
I compiled and tested the latest git kernel with the new PowerPC updates 5.13-2 today. Unfortunately
the Xorg issue still exists.
If I revert the PowerPC updates 5.13-1 and 5.13-2 then Xorg works without any
problems.
Please check the BookE changes in the PowerPC updates 5.13-1 because my Book3S machines aren't
affected by this issue.
On my side, book3e (corenet64_smp_defconfig) built with GCC 10.1 works well
with QEMU 2.11.2
A kernel built with the configuration you provided doesn't boot on QEMU, no output at all, even with
kernel v5.12.
What versions of GCC and QEMU are you using ?
Thanks
Christophe
