2009-05-14Add new drm_intel_get_pipe_from_crtc_id function.Carl Worth
This wraps the new DRM_IOCTL_I915_GET_PIPE_FROM_CRTC_ID ioctl, allowing applications to discover the pipe number corresponding to a given CRTC ID. This is necessary for doing pipe-specific operations such as waiting for vblank on a given CRTC.
2009-05-12libdrm/intel: add drm_intel_bo_disable_reuse apiKeith Packard
Scanout buffers need to be freed through the kernel as it holds a reference to them; exposing this API allows applications allocating scanout buffers to flag them as not reusable. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net>
2009-03-26libdrm/intel: support GTT maps correctlyJesse Barnes
libdrm has some support for GTT mapping already, but there are bugs with it (no surprise since it hasn't been used much). In fixing 20803, I found that sharing bo_gem->virtual was a bad idea, since a previously mapped object might not end up getting GTT mapped, leading to corruption. So this patch splits the fields according to use, taking care to unmap both at free time (but preserving the map caching). There's still a risk we might run out of mappings (there's a sysctl tunable for max number of mappings per process, defaulted to 64k or so it looks like) but at least GTT maps will work with these changes (and some others for fixing PAT breakage in the kernel).

2009-02-21intel: Add a new bufmgr alloc function to get BOs ready for rendering to.Eric Anholt
This avoids using the oldest BO in the BO cache and waiting for it to be idle before we turn around and render to it with the GPU. Thanks to Chris Wilson for pointing out how silly we were being.
2008-12-17libdrm: add mode setting filesJesse Barnes
Add mode setting files to libdrm, including xf86drmMode.* and the new drm_mode.h header. Also add a couple of tests to sanity check the kernel interfaces and update code to support them.
2008-12-10Revert "Merge branch 'modesetting-gem'"Jesse Barnes
This reverts commit 6656db10551bbb8770dd945b6d81d5138521f208. We really just want the libdrm and ioctl bits, not all the driver stuff.

2008-12-02intel: Add a function for setting (GTT,GTT) domain, for use by UXA.Eric Anholt
This function can also serve the role that the bo_wait_rendering did, when write_enable is unset.

2008-11-13libdrm: add support for i915 GTT mapping ioctlJesse Barnes
Add a drm_intel_gem_bo_map_gtt() function for mapping a buffer object through the aperture rather than directly to its CPU cacheable memory.
2008-10-30intel: Rename dri_ and intel_ symbols to drm_intel_.Eric Anholt
I wanted to avoid doing this, as it's a bunch of churn, but there was a conflict between the dri_ symbols in libdrm and the symbols that were in Mesa in 7.2, which broke Mesa 7.2 AIGLX when the 2D driver had loaded new libdrm symbols. The new naming was recommended by cworth for giving the code a unique prefix identifying where the code lives. Additionally, take the opportunity to fix up two API mistakes: emit_reloc's arguments were in a nonsensical order, and set_tiling lacked the stride argument that the kernel will want to use soon. API compatibility with released code is maintained using #defines.

2008-09-30intel bufmgr: reinstate buffer handle trackingJesse Barnes
We need a way of getting at the underlying handle for use with mode setting. We can either export it in the dri_bo object or provide a new callback to get it.
2008-09-10intel: move drm calls to exec buffers to libdrm_intel.Eric Anholt
This avoids duplicating the effort in 3 places. Also, added emit/wait fence callbacks back in bufmgr_fake since we need it for non-drm 2d. Sigh.
2008-09-10intel: Move IRQ emit/wait from callbacks into the bufmgr.Eric Anholt
In the process, work around the glaring bugs of the kernel irq wait function.
2008-09-10Move intel libdrm stuff to libdrm_intel.soEric Anholt
dri_bufmgr.h is replaced by intel_bufmgr.h, and several functions are renamed, though the structures and many functions remain dri_bufmgr_* and dri_bo_*

2008-06-05Add a function to bufmgr_fake to evict all buffers in the GTT.Eric Anholt
This will be used by the X Server for VT switch.
