drm: reorganise drm tree to be more future proof.

2008-07-14T00:45:01+00:00

With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie

Revert "drm/vbl rework: rework how the drm deals with vblank."

2008-05-07T02:15:39+00:00

This reverts commit ac741ab71bb39e6977694ac0cc26678d8673cda4. Okay this looks like wasn't as fully baked as I'd led myself to believe. Revert for now for further baking. Signed-off-by: Dave Airlie

drm/vbl rework: rework how the drm deals with vblank.

2008-04-26T08:01:07+00:00

Other Authors: Michel Dänzer mga: Ian Romanick via: Thomas Hellstrom This re-works the DRM internals to provide a better interface for drivers to expose vblank on multiple crtcs. It also includes work done by Michel on making i915 triple buffering and pageflipping work properly. Signed-off-by: Dave Airlie

drm: remove a bunch of typedefs on the userspace interface

2007-07-11T05:27:12+00:00

This moves a bunch of typedefs into a !defined __KERNEL__ to keep userspace API compatiblity, it changes all internal usages to structs/enum/unions. Signed-off-by: Dave Airlie

drm/i915: Add support for the G33, Q33, and Q35 chipsets.

2007-06-10T05:58:19+00:00

These require that the status page be referenced by a pointer in GTT, rather than phsyical memory. So, we have the X Server allocate that memory and tell us the address, instead. Signed-off-by: Dave Airlie

drm: i915: Add SAREA fileds for determining which pipe to sync window buffer swaps to.

drm: DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead

2006-12-07T04:53:30+00:00

of pipe number. 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(). Signed-off-by: Dave Airlie

drm: i915: Add ioctl for scheduling buffer swaps at vertical blanks.

2006-12-07T04:53:29+00:00

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. Signed-off-by: Dave Airlie

drm: Add support for Intel i965G chipsets.

2006-09-21T19:32:32+00:00

This is a patch prepared by Guangdeng Liao based off of Tungsten Graphics's final code drop. From: Alan Hourihane Signed-off-by: Dave Airlie

Add i915 ioctls to configure pipes for vblank interrupt.

2006-06-24T07:32:58+00:00

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. From: Keith Packard via DRM CVS Signed-off-by: Dave Airlie
