The point is to share more code between the PFB/PGRAPH tile region hooks, and give the hardware specific functions a chance to allocate per-region resources. Signed-off-by:

nouveau_bo_move_m2mf() needs to lock the kernel channel, and it may be called from the pushbuf IOCTL with an user channel already locked. Use a separate subclass for the kernel channel mutex because this is legitimate mutex nesting. Signed-off-by:

In a multihead setup vblank interrupts may end up enabled in both heads. In that case we want to ignore the vblank interrupts coming from the wrong CRTC to avoid tearing and unbalanced calls to drm_vblank_get/put (fdo bug 31074). Reported-by:

nouveau_fence_* functions are not type safe, which could lead to bugs. Additionally every use of nouveau_fence_unref had to cast struct nouveau_fence to void **. Fix it by renaming old functions and creating static inline functions with new prototypes. We still need old functions, because we pass function pointers to ttm. As we are wrapping functions, drop unused "void *arg" parameter where possible. Signed-off-by:

Only supported on NV50+ so far, and disabled by default currently. The module parameter "msi=1" will enable it. There's a kernel bug which will cause this to fail if the module (or the NVIDIA binary driver) has ever been loaded before loading nouveau with MSI enabled. As such, this is only safe to enable if you have nouveau load on boot, and don't wish to ever reload it. The workaround is to "echo 0 > /sys/bus/pci/devices/<device>/enable" until the enable count reads 0. Then you should be able to load nouveau with MSI enabled. Signed-off-by: -

The structs themselves, as well as the non-sw object creation function are probably very misnamed now. That's a problem for later :) Signed-off-by: -

nouveau_channel_ref() takes a "weak" channel reference that doesn't prevent the hardware channel resources from being released, it just keeps the channel data structure alive. 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:

This isn't correct everywhere yet, but since we don't use the data yet it's perfectly safe to push in, and the information we gain from logs will help to fix the remaining issues. v2 (Ben Skeggs <bskeggs@redhat.com>): - fixed up formatting - free parsed timing info on takedown - switched timing table printout to debug loglevel Signed-off-by:
