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

[Gustavo Sousa]

Quoting Gustavo Sousa (2023-11-16 18:39:58-03:00)
>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.
