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: -

Not an issue right now, we're forced to 64k size/alignment by the BO allocator anyway. This won't be the case soon. Signed-off-by: -

This really needs cleaning up somehow, and probably investigate what's needed to do this on earlier generations. NVIDIA do something similar there too. Signed-off-by: -

We previously added all the available classes for the entire generation, even though the objects wouldn't work on the hardware. 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: -

It needs a "strong" channel reference because it actually writes to the channel pushbuf, otherwise the corresponding FIFO context could get kicked off in the middle of nouveau_fence_sync(). Signed-off-by:

Fences didn't increment the channel reference count, and the fenced channel could go away at any time. Fixes a potential race in nouveau_fence_update(). 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:

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:
