2006-09-29i915: Bump minor again to differentiate from vsync changes.Michel Dänzer
2006-09-29i915: Avoid mis-counting vblank interrupts when they're only enabled for pipe A.Michel Dänzer
It looks like 'after a while', I915REG_INT_IDENTITY_R for some reason always has VSYNC_PIPEB_FLAG set in the interrupt handler, even though pipe B is disabled. So we only increase dev->vbl_received if the corresponding bit is also set in dev->vblank_pipe. (cherry picked from 881ba569929ceafd42e3c86228b0172099083d1d commit)
2006-09-29i915: Bump minor for swap scheduling ioctl and secondary vblank support.Michel Dänzer
(cherry picked from 2627131e5d0c8cd5e3f0db06451c2e7ae7569b1b commit)
2006-09-29i915_vblank_swap: Add support for DRM_VBLANK_NEXTONMISS.Michel Dänzer

2006-09-29Only return EBUSY after we've established we need to schedule a new swap.Michel Dänzer

2006-09-29Core vsync: Don't clobber target sequence number when scheduling signal.Michel Dänzer
It looks like this would have caused signals to always get sent on the next vertical blank, regardless of the sequence number. (cherry picked from cf6b2c5299e9be3542d4deddfd05d5811f11d2ef commit)
2006-09-29Core vsync: Add flag DRM_VBLANK_NEXTONMISS.Michel Dänzer
When this flag is set and the target sequence is missed, wait for the next vertical blank instead of returning immediately. (cherry picked from 89e323e4900af84cc33219ad24eb0b435a039d23 commit)
2006-09-29Fix 'sequence has passed' condition in i915_vblank_swap().Michel Dänzer
(cherry picked from 7f09f957d9a61ac107f8fd29128d7899a3e8a228 commit)
2006-09-29Add SAREA fileds for determining which pipe to sync window buffer swaps to.Michel Dänzer
(cherry picked from c2bdb76814755c9ac6e66a8815f23af0fe4f3a91 commit)
2006-09-29Add definition of DRM_VBLANK_SECONDARY.Michel Dänzer
(cherry picked from 84b38b63f05e04ade8b1ddfb770047fd86de0d64 commit)
2006-09-29Make handling of dev_priv->vblank_pipe more robust.Michel Dänzer
Initialize it to default value if it hasn't been set by the X server yet. In i915_vblank_pipe_set(), only update dev_priv->vblank_pipe and call i915_enable_interrupt() if the argument passed from userspace is valid to avoid corrupting dev_priv->vblank_pipe on invalid arguments. (cherry picked from 87c57cba1a70221fc570b253bf3b24682ef6b894 commit)
2006-09-29DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead of pipe number.Michel Dänzer
Handle relative as well as absolute target sequence numbers. Return error if target sequence has already passed, so userspace can deal with this situation as it sees fit. On success, return the sequence number of the vertical blank when the buffer swap is expected to take place. Also add DRM_IOCTL_I915_VBLANK_SWAP definition for userspace code that may want to use ioctl() instead of drmCommandWriteRead(). (cherry picked from d5a0f107511e128658e2d5e15bd7e6215c507f29 commit)
2006-09-29Change first valid DRM drawable ID to be 1 instead of 0.Michel Dänzer
This makes it easier for userspace to know when it needs to allocate an ID. Also free drawable information memory when it's no longer needed. (cherry picked from df7551ef7334d728ec0371423661bb403d3e270a commit)

2006-09-29i915: Add ioctl for scheduling buffer swaps at vertical blanks.Michel Dänzer
This uses the core facility to schedule a driver callback that will be called ASAP after the given vertical blank interrupt with the HW lock held. (cherry picked from 257771fa290b62d4d2ad896843cf3a207978d0bb commit)

(cherry picked from 98a89504589427a76c3f5cfa2266962a1a212672 commit)
2006-09-29Only reallocate cliprect memory if the number of cliprects changes.Michel Dänzer
Also improve diagnostic output. (cherry picked from af48be1096221d551319c67a9e782b50ef58fefd commit)
2006-09-29Add support for tracking drawable information to coreMichel Dänzer
Actually make the existing ioctls for adding and removing drawables do something useful, and add another ioctl for the X server to update drawable information. The only kind of drawable information tracked so far is cliprects. (cherry picked from 29598e5253ff5c085ccf63580fd24b84db848424 commit)
2006-09-29Add support for interrupt triggered driver callback with lock held to DRM core.Michel Dänzer
(cherry picked from d817cc1f30060fcc4a85a05b2de8a2a1687421b5 commit)
2006-09-29Add support for secondary vertical blank interrupt to i915 driver.Michel Dänzer
When the vertical blank interrupt is enabled for both pipes, pipe A is considered primary and pipe B secondary. When it's only enabled for one pipe, it's always considered primary for backwards compatibility. (cherry picked from 0c7d7f43610f705e8536a949cf2407efaa5ec217 commit)

2006-09-29Add a new buffer flag.Thomas Hellstrom
Fix up some comments.
2006-09-29Fix buffer manager takedown error.Thomas Hellstrom
Prepare for the possibility to evict all buffers from vram / agp. This will be used by the X server when, for example, switching vts.
2006-09-29i915: Only schedule vblank tasklet if there are scheduled swaps pending.Michel Dänzer
This fixes issues on X server startup with versions of xf86-video-intel that enable the IRQ before they have a context ID.
