drm/prime: expose capability flags for userspace.

2012-05-18T10:12:16Z

This lets the kernel tell userspace if the device supports prime import/export. This is useful for -modesetting at least, but would be nice for other drivers. Reviewed-by: Chris Wilson Signed-off-by: Dave Airlie

drm: add generic ioctls to get/set properties on any object

2012-05-17T10:11:22Z

Useless for connector properties (since they already have their own ioctls), but useful when we add properties to CRTCs, planes and other objects. Reviewed-by: Eugeni Dodonov Reviewed-by: Rob Clark Tested-by: Rob Clark Signed-off-by: Paulo Zanoni Signed-off-by: Dave Airlie

drm: base prime/dma-buf support (v5)

2012-03-30T10:52:44Z

This adds the basic drm dma-buf interface layer, called PRIME. This commit doesn't add any driver support, it is simply and agreed upon starting point so we can work towards merging driver support for the next merge window. Current drivers with work done are nouveau, i915, udl, exynos and omap. The main APIs exposed to userspace allow translating a 32-bit object handle to a file descriptor, and a file descriptor to a 32-bit object handle. The flags value is currently limited to O_CLOEXEC. Acknowledgements: Daniel Vetter: lots of review Rob Clark: cleaned up lots of the internals and did lifetime review. v2: rename some functions after Chris preferred a green shed fix IS_ERR_OR_NULL -> IS_ERR v3: Fix Ville pointed out using buffer + kmalloc v4: add locking as per ickle review v5: allow re-exporting the original dma-buf (Daniel) Reviewed-by: Daniel Vetter Reviewed-by: Rob Clark Reviewed-by: Sumit Semwal Reviewed-by: Inki Dae Acked-by: Ben Widawsky Signed-off-by: Dave Airlie

drm: add some caps for userspace to discover more info for dumb KMS driver (v2)

2012-02-16T18:35:11Z

For the simple KMS driver case we need some more info about what the preferred depth and if a shadow framebuffer is preferred. I've only added this for intel/radeon which support the dumb ioctls so far. If you need something really fancy you should be writing a real X.org driver. v2: drop cursor information, just return an error from the cursor ioctls and we can make userspace fallback to sw cursor in that case, cursor info was getting too messy, best to start smaller.

drm: add an fb creation ioctl that takes a pixel format v5

2011-11-15T19:53:23Z

To properly support the various plane formats supported by different hardware, the kernel must know the pixel format of a framebuffer object. So add a new ioctl taking a format argument corresponding to a fourcc name from the new drm_fourcc.h header file. Implement the fb creation hooks in terms of the new mode_fb_cmd2 using helpers where the old bpp/depth values are needed. v2: create DRM specific fourcc header file for sharing with libdrm etc v3: fix rebase failure and use DRM fourcc codes in intel_display.c and update commit message v4: make fb_cmd2 handle field into an array for multi-object formats pull in Ville's fix for the memcpy in drm_plane_init apply Ville's cleanup to zero out fb_cmd2 arg in drm_mode_addfb v5: add 'flags' field for interlaced support (from Ville) Signed-off-by: Ville Syrjälä Acked-by: Alan Cox Reviewed-by: Rob Clark Signed-off-by: Jesse Barnes Signed-off-by: Dave Airlie

drm: add plane support v3

2011-11-15T19:53:10Z

Planes are a bit like half-CRTCs. They have a location and fb, but don't drive outputs directly. Add support for handling them to the core KMS code. v2: fix ABI of get_plane - move format_type_ptr to the end v3: add 'flags' field for interlaced support (from Ville) Acked-by: Alan Cox Reviewed-by: Rob Clark Reviewed-by: Daniel Vetter Signed-off-by: Jesse Barnes Signed-off-by: Dave Airlie

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
