2014-09-11Merge remote-tracking branch 'airlied/drm-next' into topic/vblank-reworkDaniel Vetter5104-344021/+251887
Dave asked me to do the backmerge before sending him the revised pull request, so here we go. Nothing fancy in the conflicts, just a few things changed right next to each another. Conflicts: drivers/gpu/drm/drm_irq.c Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2014-09-11drm: Clarify vblank ts/scanoutpos sampling #definesDaniel Vetter5-6/+6
I've read INVBL as "invalid backlight" and got mightly confused. The #defines are already fairly long and we can afford to extend them a bit more without resulting in ugly code all over. I'm not sure how useful the complicated bitmask return value of these functions really are since no one checks them. But for now let's keep things as is.

2014-09-11drm: Simplify return value of drm_get_last_vbltimestampDaniel Vetter1-10/+15
Imo u32 hints at a register value, but in reality all callers only care whether the sampled timestamp is precise or not. So give them just a bool. Also move the declaration out of drmP.h, it's only used in drm_irq.c. v2: Also drop the EXPORT_SYMBOL, spotted by Mario.

2014-09-11drm: Only update final vblank count when precise ts is availableDaniel Vetter1-1/+8
Drivers without a hardware vblank counter simply can't account for the vblanks that happened while the vblank interrupt was off. To check this grab a vblank timestamp and if the result is dubious follow the normal save-and-disable logic. Drivers should prevent this by setting vblank_disable_allowed = false, but since running vblank interrupts constantly is not good for power consumption most drivers lie. Testing for precise vblank timestamps is the next best thing we can check for.

2014-09-11drm: Really never disable vblank irqs for offdelay==0Daniel Vetter1-2/+4
With the new support for immediate vblank disabling we always disabled the vblank interrupt right away, irrespective of the vblank offdelay setting. But being able to let vblanks run forever is fairly useful for debugging, so restore that behaviour.

2014-09-10drm: add driver->set_busid() callbackDavid Herrmann29-9/+56
One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

2014-09-10drm: Use vblank_disable_and_save in drm_vblank_cleanup()Mario Kleiner1-1/+5
Calling vblank_disable_fn() will cause that function to no-op if !dev->vblank_disable_allowed for some kms drivers, e.g., on nouveau-kms. This can cause the gpu vblank irq's to not get disabled before freeing the dev->vblank array, so if a vblank irq fires and calls into drm_handle_vblank() after drm_vblank_cleanup() completes, it will cause use-after-free access to dev->vblank array. Call vblank_disable_and_save unconditionally, so vblank irqs are guaranteed to be off, before we delete the data structures on which they operate.

2014-09-10drm: drop DRM_DEBUG_CODEDavid Herrmann4-32/+12
DRM_DEBUG_CODE is currently always set, so distributions enable it. The only reason to keep support in code is if developers wanted to disable debug support. Sounds unlikely. All the DRM_DEBUG() printks are still guarded by a drm_debug read. So if its cacheline is read once, they're discarded pretty fast.. There should hardly be any performance penalty, it's even guarded by unlikely().

Furthermore, replace asm/current.h with sched.h, which includes asm/current.h unconditionally. This way we get the same effect and avoid direct asm/ includes. Furthermore, drop the weird __alpha__ protection. It's safe to include sched.h everywhere (and the wait.h comment doesn't apply, anyway).
