drm/radeon: use common fence implementation for fences, v4
Changes since v1:
- Kill the sw interrupt dance, add and use
radeon_irq_kms_sw_irq_get_delayed instead.
- Change custom wait function, lockdep complained about it.
Holding exclusive_lock in the wait function might cause deadlocks.
Instead do all the processing in .enable_signaling, and wait
on the global fence_queue to pick up gpu resets.
- Process all fences in radeon_gpu_reset after reset to close a race
with the trylock in enable_signaling.
Changes since v2:
- Small changes to work with the rewritten lockup recovery patches.
Changes since v3:
- Call radeon_fence_schedule_check when exclusive_lock cannot be
acquired to always cause a wake up.
- Reset irqs from hangup check.
- Drop reading seqno in the callback, use cached value.
- Fix indentation in radeon_fence_default_wait
- Add a radeon_test_signaled function, drop a few test_bit calls.
- Make to_radeon_fence global.
