drm/vblank: update recently added vbl interface to be more future proof.

2011-03-24T11:28:46Z

This makes the interface a bit cleaner by leaving a single gap in the vblank bit space instead of creating two gaps. Suggestions from Michel on mailing list/irc. Reviewed-by: Michel Dänzer Signed-off-by: Dave Airlie

drm/kernel: vblank wait on crtc > 1

2011-03-20T23:25:54Z

Below is a patch against drm-next branch of 2.6.38-rc8+ kernel that adds the capability to wait on vblank events for CRTCs that are greater than 1 and thus cannot be represented with primary/secondary flags in the legacy interface. It was discussed on the dri-devel list in these two threads: http://lists.freedesktop.org/archives/dri-devel/2011-March/009009.html http://lists.freedesktop.org/archives/dri-devel/2011-March/009025.html This patch extends the interface to drm_wait_vblank ioctl so that crtc>1 can be represented. It also adds a new capability to drm_getcap ioctl so that the user space can check whether the new interface to drm_wait_vblank is supported (and fall back to the legacy interface if not) Signed-off-by: Ilija Hadzic Reviewed-by: Mario Kleiner Acked-by: Mario Kleiner Reviewed-by: Alex Deucher Tested-by: Alex Deucher Signed-off-by: Dave Airlie

drm: add cap bit to denote if dumb ioctl is available or not.

drm/core: add ioctl to query device/driver capabilities

2011-03-04T04:47:30Z

We're coming to see a need to have a set of generic capability checks in the core DRM, in addition to the driver-specific ioctls that already exist. This patch defines an ioctl to do as such, but does not yet define any capabilities. [airlied: drop the driver callback for now.] Signed-off-by: Ben Skeggs Signed-off-by: Dave Airlie

drm: dumb scanout create/mmap for intel/radeon (v3)

2011-02-07T02:16:14Z

This is just an idea that might or might not be a good idea, it basically adds two ioctls to create a dumb and map a dumb buffer suitable for scanout. The handle can be passed to the KMS ioctls to create a framebuffer. It looks to me like it would be useful in the following cases: a) in development drivers - we can always provide a shadowfb fallback. b) libkms users - we can clean up libkms a lot and avoid linking to libdrm_*. c) plymouth via libkms is a lot easier. Userspace bits would be just calls + mmaps. We could probably mark these handles somehow as not being suitable for acceleartion so as top stop people who are dumber than dumb.

drm: move ttm global code to core drm

2010-08-03T23:46:06Z

I wrote this for the prime sharing work, but I also noticed other external non-upstream drivers from a large company carrying a similiar patch, so I may as well ship it in master. Signed-off-by: Dave Airlie

Merge remote branch 'anholt/drm-intel-next' into drm-linus

This merges the upstream Intel tree and fixes up numerous conflicts due to patches merged into Linus tree later in -rc cycle. Conflicts: drivers/char/agp/intel-agp.c drivers/gpu/drm/drm_dp_i2c_helper.c drivers/gpu/drm/i915/i915_irq.c drivers/gpu/drm/i915/i915_suspend.c

drm: Add dirty ioctl and property

2009-12-03T23:25:47Z

This commit adds a ioctl and property to allow userspace to notify the kernel that a framebuffer has changed. Instead of snooping the command stream this allows finer grained tracking of which areas have changed. The primary user for this functionality is virtual hardware like the vmware svga device, but also Xen hardware likes to be notify. There is also real hardware like DisplayLink and DisplayPort that might take advantage of this ioctl. Signed-off-by: Jakob Bornecrantz Signed-off-by: Dave Airlie

drm: use page flip event to signal flip completion

2009-12-01T17:11:53Z

We don't actually know which frame number the flip will complete on, so userspace needs a specific flip notification to tell it when the last flip completed. Signed-off-by: Jesse Barnes Signed-off-by: Eric Anholt Acked-by: Kristian Høgsberg
