Hi,
Fedora kernel 6.10 for aarch64 now includes the Intel xe driver. Great!
Unfortunately, 2D only, as libdrm and mesa are still built without Intel
support.

Hope this gets resolved soon.

Hi,
It has been reported that Intel Xe kernel drivers build and run fine on
aarch64 in 2D mode.
3D support comes after enabling Intel in libdrm and mesa, but currently
is not stable.
Supposedly, this will be greatly improved in kernel 6.11 which will have
many Xe updates.
Having 2D now would already be a plus.
I had read it's all a WIP but enabling it now doesn't affect other
users and usercases so it doesn't hurt. It makes it easier for those
that wish to try it but of course there's no guarantee as to how well
it will work :)

Hi,
Upstream has support for Intel Xe graphics in all of kernel, libdrm and
mesa, yet all of these packages are built with Intel support disabled on
aarch64.
Intel Xe drivers, unlike i915 are architecture independent.
On x86_64, they conflict with i915 drivers, so an elaborate scheme is
used to allow both drivers to coexist.
On aarch64, Intel Xe has no legacy counterpart, so no conflict either.
All the more reason to enable Intel Xe on aarch64, just like on x86_64.
Intel Xe support may not be perfect on aarch64, but this is just as true
on x86_64.
When it first landed upstream it was still x86 only and they said they
were working on it. I did see there were patches upstream to fix the
issues. I'll take a look at what's required to build it multi arch.
