during the review of the fix for locks problems in drm_wait_vblank, a couple of false concerns were raised about how the drm_vblank_get and drm_vblank_put are used in this function; it turned out that the code is correct and that it cannot be simplified add a few comments to explain non-obvious flows in the code, to prevent "false alarms" in the future v2: incorporate comments received from Daniel Vetter Signed-off-by:

drm_wait_vblank must be DRM_UNLOCKED because otherwise it will grab the drm_global_mutex and then go to sleep until the vblank event it is waiting for. That can wreck havoc in the windowing system because if one process issues this ioctl, it will block all other processes for the duration of all vblanks between the current and the one it is waiting for. In some cases it can block the entire windowing system. v2: incorporate comments received from Daniel Vetter and Michel Daenzer. v3/v4: after a lengty discussion with Daniel Vetter, it was concluded that the only thing not yet protected with locks and atomic ops is the write to dev->last_vblank_wait. It's only used in a debug file in proc, and the current code already employs no correct locking: the proc file only takes dev->struct_mutex, whereas drm_wait_vblank implicitly took the drm_global_mutex. Given all this, it's not worth bothering to try to fix the locks at this time. Signed-off-by: -

Nouveau, when configured with debugfs, creates debugfs files for every channel, so structure holding list of files needs to be protected from simultaneous changes by multiple threads. Without this patch it's possible to hit kernel oops in drm_debugfs_remove_files just by running a couple of xterms with looped glxinfo. Signed-off-by:

Michel Dänzer authored
This was only the case if the GPU reset was triggered from the CS ioctl, otherwise other processes could happily enter the CS ioctl and wreak havoc during the GPU reset. This is a little complicated because the GPU reset can be triggered from the CS ioctl, in which case we're already holding the mutex, or from other call paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't allow recursive locking or finding out the mutex owner, so we need to handle this with helper functions which allow recursive locking from the same process.

Most serious is for chips with only 1 TPC, we'd get stuck in an infinite loop. The fix here will slightly change the setup for all other chipsets too, but, it shouldn't matter too much, and this all needs figuring out and likely redone anyway. Signed-off-by: -
