nouveau_channel_put() can be executed after the 'refcount == 0' check in nouveau_channel_get() and before the channel reference count is incremented. In that case CPU0 will take the context down while CPU1 thinks it owns the channel and 'refcount == 1'. Signed-off-by:

The destroy_context() engine hooks call gpuobj management functions to release the channel resources, these functions use HARDIRQ-unsafe locks whereas destroy_context() is called with the HARDIRQ-safe context_switch_lock held, that's a lock ordering violation. Push the engine-specific channel destruction logic into destroy_context() and let the hardware-specific code lock and unlock when it's actually needed. Change the engine destruction order to avoid a race in the small gap between pgraph and pfifo context uninitialization. Reported-by:

No other driver uses this, and userspace should be responsible for handling locking between them if they share BOs. Signed-off-by: -

This fixes a race condition between fbcon acceleration and TTM buffer moves. To reproduce: - start X - switch to vt and "while (true); do dmesg; done" - switch to another vt and "sleep 2 && cat /path/to/debugfs/dri/0/evict_vram" - switch back to vt running dmesg We don't make use of this on any other channel yet, they're currently protected by drm_global_mutex. This will change in the near future. Signed-off-by: -

A future commit will add locking to the DRM's channel, and there's numerous problems that come up if we allow printk from an interrupt context to be accelerated. It seems saner to just disallow it completely. As a nice side-effect, all the "to accel or not to accel" logic gets moved out of the chipset-specific code. Signed-off-by: -
