Hi Dave and Sima,

Early drm-xe-next pull request for 6.12. Main reason for being much
earlier than usual is to have the additional SIMD16 EU reported as it's
a needed UAPI for Lunar Lake and Battlemage. It's sitting in drm-xe-next
for a few weeks and userspace already testing with it.

There's also a minor uapi change with change of error return code. The
other 2 already propagated via -fixes.

Other changes bring general improvements and cleanups to the driver,
further support for SR-IOV as well as head Lunar Lake and Battlemage to
the finish line of being officially exposed by the driver. Some bits
still influx, so not yet there though.

thanks
Lucas De Marchi
