2007-05-26drm: spinlock initializer cleanupThomas Gleixner
2007-05-10Allow vblank interrupts to remain disabled across VT switch.Keith Packard
i915_driver_irq_postinstall was forcing vblank interrupts to pipe A when called with vblank interrupts disabled. This caused vblank interrupts to be accidentally re-enabled when VT switching the X server. Instead, start the driver with vblank interrupts enabled on pipe A to support older X servers, but then leave control over the state to the X server if it is able to do so.
2007-04-28move i915 to new drm_wait_on functionDave Airlie
2007-04-03Make sure we ack irqs before we read a breadcrumb so thatThomas Hellstrom
breadcrumb updates that occur _AFTER_ we've read the breadcrumb really generates a new IRQ.
2007-02-28i915: Eliminate dev_priv->current_page.Michel Dänzer
Always use dev_priv->sarea_priv->pf_current_page directly. This allows clients to modify it as well while they hold the HW lock, e.g. in order to sync pages between pipes.
2007-02-28i915: Fix test for synchronous flip affecting both pipes.Michel Dänzer
2007-02-22i915: Add support for scheduled buffer swaps to be done as flips.Michel Dänzer
Unfortunately, emitting asynchronous flips during vertical blank results in tearing. So we have to wait for the previous vertical blank and emit a synchronous flip.
2007-02-19i915: Improved page flipping support, including triple buffering.Michel Dänzer
Pages are tracked independently on each pipe. Bump the minor version for 3D clients to know page flipping is usable, and bump driver date.
2007-02-19i915: Unify breadcrumb emission.Michel Dänzer

2007-01-02i915: Fix a DRM_ERROR that should be DRM_DEBUG.Michel Dänzer
It would clutter up the kernel output in a situation which is legitimate before X.org 7.2 and handled correctly by the 3D driver.
2006-11-27i915_vblank_tasklet: Try harder to avoid tearing.Michel Dänzer
Previously, if there were several buffer swaps scheduled for the same vertical blank, all but the first blit emitted stood a chance of exhibiting tearing. In order to avoid this, split the blits along slices of each output top to bottom.

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. (cherry picked from 7af93dd9849442270ec89cb4bbeef5bfd4f9e424 commit)
2006-09-29i915: Only initialize IRQ fields in postinstall, not the PIPE_SET ioctl.Michel Dänzer
Some other minor changes in preparation for actually disabling user interrupts.
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)

(cherry picked from 50a0284a61d4415c0ebdb02decee76ef3115007a commit)
2006-09-29Fix 'sequence has passed' condition in i915_vblank_swap().Michel Dänzer
(cherry picked from 7f09f957d9a61ac107f8fd29128d7899a3e8a228 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)
2006-09-29i915: 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)
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)

2006-09-15Some bugfixes.Thomas Hellstrom
Change the fence object interface somewhat to allow some more flexibility. Make list IOCTLS really restartable. Try to avoid busy-waits in the kernel using immediate return to user-space with an -EAGAIN.
2006-09-12More bugfixes.Thomas Hellstrom
Disable the i915 IRQ turnoff for now since it seems to be causing problems.

2006-09-05i915: Only turn on user IRQs when they are needed.Thomas Hellstrom
2006-08-29Checkpoint commit. Buffer object flags and IOCTL argument list.Thomas Hellstrom
2006-08-21i915 fence object driver implementing 2 fence object types:Thomas Hellstrom
0x00 EXE fence. Signals when command stream interpreter has reached the point where the fence was emitted. 0x01 FLUSH fence. Signals when command stream interpreter has reached the point where the fence was emitted, and all previous drawing operations have been completed and flushed. Implements busy wait (for fastest response time / high CPU) and lazy wait (User interrupt or timer driven).

2006-08-08Add support for Intel i965G chipsets.Alan Hourihane
This is a patch prepared by Guangdeng Liao based off of Tungsten Graphics's final code drop.

2006-06-21i915: Save vblank pipe configuration to restore on resumeKeith Packard
2006-06-19Add i915 ioctls to configure pipes for vblank interrupt.Keith Packard
i915 vblanks can be generated from either pipe a or b, however a disabled pipe generates no interrupts. This change allows the X server to select which pipe generates vblank interrupts.
2006-03-25radeon fix up the PCI ids for new memory map like the kernel one.. notDave Airlie
perfect but should be very safe... align some other kernel bits i810 align with kernel

2006-02-09Update the hardware breadcrumb in the sarea on irq reception so thatKeith Whitwell
clients can avoid an ioctl waiting on fences that have already been received. Would be even better if the hardware did the update itself.
2005-12-28Add vblank support to i915 DRM..Dave Airlie
2005-11-28Assert an MIT copyright on sis_drm.h, since one was lacking and I createdEric Anholt
that particular file. Its contents have changed a good bit since the original sis code, and the original sis code didn't care much about attribution since it routinely disclaims Precision Insight/VA Linux from responsibility. Also, adjust formatting around license headers (have a comment open immediately before the "Copyright" line, not as a runon of any previous comments) for automatic processing into FreeBSD, where /*- is used to signal the beginning of license headers for automatic compilation of license lists.
