2013-07-30drm/nvc0/fb: take lock in nvc0_ram_put()Roy Spliet3-12/+26
Kernel panic caused by list corruption in ltcg seems to indicate a concurrency issue. Take mutex of pfb like nv50_ram_put() to eliminate concurrency. V2: Separate critical section into separate function, avoid taking the lock twice on NVC0 Signed-off-by: Roy Spliet <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2013-07-30drm/nouveau/core: xtensa firmware size needs to be 0x40000 no matter whatIlia Mirkin1-1/+7
The current logic is wrong since we send fw->size >> 8 to the card. Rounding the size up by 0x100 and 0x1000 didn't seem to help, the card still hung, so go back to what the blob does -- 0x40000. Signed-off-by: Ilia Mirkin <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2013-07-10drm/nouveau: do not allow negative sizes for nowMaarten Lankhorst1-0/+6
The API allows up to 64-bits allocations, but size is handled as int inside nouveau almost everywhere. Until this is fixed it's better to prevent negative sizes. The 256 kB before INT_MAX is paranoia, because of the large page aligning below that could flip it above INT_MAX.

2013-07-10drm/nouveau: add falcon interrupt handlerMaarten Lankhorst7-0/+26

2013-07-10drm/nouveau: use dedicated channel for async moves on GT/GF chipsets.Ben Skeggs2-3/+15
The moves themselves were generally async to graphics previously, with the exception that if the "main" channel is used to synchronise a page flip at the same time, it can end up blocked for a noticable amount of time for large buffer moves. Not really critical, and there's better ways of handling this, but they are all rather invasive, so this is fine for now. Based on a patch by Maarten Lankhorst addressing the same issue.

2013-07-10drm/nouveau: do not unpin in nouveau_gem_object_delMaarten Lankhorst2-8/+5
This should no longer be required, and is harmful for framebuffer pinning. Also add a warning if unpin causes the pin count to drop below 0. Signed-off-by: Maarten Lankhorst <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>

2013-07-10drm/nouveau: fix locking issues in page flipping pathsBen Skeggs3-36/+22
b580c9e2b7ba5030a795aa2fb73b796523d65a78 introduced additional problems while trying to solve issues that became apparent while porting to the new reservation stuff. The major problem was that the the previously mentioned patch took the client mutex earlier than previously, but the pinning of new_bo can can potentially cause a buffer move, which would result in attempting to acquire the same mutex again. This commit attempts to fix that "fix". Thanks to Maarten for the tips on keeping lockdep happy and cooking :) Reported-by: Maarten Lankhorst <[email protected]> Signed-off-by: Ben Skeggs <[email protected]> Acked-by: Maarten Lankhorst <[email protected]>

There are missing parts to handle error in drm_open_helper(). The priv->minor, assigned by idr_find() which can return NULL, should be checked whether it is NULL or not before referencing it. put_pid(), drm_gem_release(), and drm_prime_destory_file_private() should be called when error happens after their pair functions are called. If an error occurs after executing dev->driver->open() which allocates driver specific per-file private data, then the private data should be released.

If raw_edid of drm_edid_block_vaild() is null, it will crash, so checking in bad label is removed and instead assertion is added at the top of the function.

2013-07-04drm: Convert drm class driver from legacy pm ops to dev_pm_opsShuah Khan1-4/+29
Convert drivers/gpu/drm class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, drm class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the drm class. drm_class_suspend() hook calls driver legacy ops with the state information. e.g: drm_class_suspend() calls into driver suspend routines via drm_dev->driver->suspend(drm_dev, state). Once drm_class_suspend() is converted to dev_pm_ops, it will no longer have access to pm_transition which it has to pass into driver legacy suspend calls. A new freeze and suspend hooks are added to address the not having access to the state information. The new freeze and suspend hooks simply call __drm_class_suspend() with the appropriate pm state information. __drm_class_suspend() is the original suspend hook with a new name.
