With the new per-crtc locking mutliple set-cursor calls could happen in parallel. Out of sheer paranoia I've opted for an irqsave spinlock. But if there's indeed an access from interrupt contexts to these regs it's already broken with the old code, so this can likely just be reduced to a normal spinlock. Otoh the pageflip completion happens from the vblank irq handler ... Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

All items on the lru list are always reservable, so this is a stupid thing to keep. Not only that, it is used in a way which would guarantee deadlocks if it were ever to be set to block on reserve. This is a lot of churn, but mostly because of the removal of the argument which can be nested arbitrarily deeply in many places. No change of code in this patch except removal of the no_wait_reserve argument, the previous patch removed the use of no_wait_reserve. v2: - Warn if -EBUSY is returned on reservation, all objects on the list should be reservable. Adjusted patch slightly due to conflicts. v3: - Focus on no_wait_reserve removal only.

Replace the goto loop with a simple for each loop, and only run the delayed destroy cleanup if we can reserve the buffer first. No race occurs, since lru lock is never dropped any more. An empty list and a list full of unreservable buffers both cause -EBUSY to be returned, which is identical to the previous situation, because previously buffers on the lru list were always guaranteed to be reservable. This should work since currently ttm guarantees items on the lru are always reservable, and reserving items blockingly with some bo held are enough to cause you to run into a deadlock. Currently this is not a concern since removal off the lru list and reservations are always done with atomically, but when this guarantee no longer holds, we have to handle this situation or end up with possible deadlocks.

By removing the unlocking of lru and retaking it immediately, a race is removed where the bo is taken off the swap list or the lru list between the unlock and relock. As such the cleanup_refs code can be simplified, it will attempt to call ttm_bo_wait non-blockingly, and if it fails it will drop the locks and perform a blocking wait, or return an error if no_wait_gpu was set. The need for looping is also eliminated, since swapout and evict_mem_first will always follow the destruction path, no new fence is allowed to be attached. As far as I can see this may already have been the case, but the unlocking / relocking required a complicated loop to deal with re-reservation. Changes since v1: - Simplify no_wait_gpu case by folding it in with empty ddestroy. - Hold a reservation while calling ttm_bo_cleanup_memtype_use again. Changes since v2: - Do not remove bo from lru list while waiting Signed-off-by: NMaarten Lankhorst <maarten.lankhorst@canonical.com> Reviewed-by: NThomas Hellstrom <thellstrom@vmware.com> Signed-off-by: NDave Airlie <airlied@redhat.com>

The few places that care should have those checks instead. This allows destruction of bo backed memory without a reservation. It's required for being able to rework the delayed destroy path, as it is no longer guaranteed to hold a reservation before unlocking. However any previous wait is still guaranteed to complete, and it's one of the last things to be done before the buffer object is freed.
