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.
