[Intel-xe] [PATCH v3 0/2] drm/xe/mmio: Make xe_mmio_wait32() aware of interrupts

[Gustavo Sousa]

The current implementation of xe_mmio_wait32() is susceptible to
preemption/interrupts causing false timeouts. This series proposes a fix
for that.

Changes in v2:
 - Add a patch moving xe_mmio_wait32() to xe_mmio.c
 - Use a barrier()-free implementation.

Changes in v3:
 - Tweak documentation for @timeout_us.
 - Add note in the commit message to better justify the move of
   xe_mmio_wait32() to xe_mmio.c.
