drm/msm: move mdp4 -> mdp/mdp4

2014-01-09T19:38:59Z

There are some little bits and pieces that mdp4 and mdp5 can share, so move things around so that we can have both in a common parent directory. Signed-off-by: Rob Clark

drm/msm: add support for msm8060ab/bstem

2014-01-09T19:38:58Z

This adds the necessary configuration for the APQ8060A SoC (dual-core krait + a320 gpu) as found on the bstem board. Signed-off-by: Rob Clark

drm/msm: add support for non-IOMMU systems

2014-01-09T19:38:58Z

Add a VRAM carveout that is used for systems which do not have an IOMMU. The VRAM carveout uses CMA. The arch code must setup a CMA pool for the device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not cool). The user can configure the VRAM pool size using msm.vram module param. Technically, the abstraction of IOMMU behind msm_mmu is not strictly needed, but it simplifies the GEM code a bit, and will be useful later when I add support for a2xx devices with GPUMMU, so I decided to keep this part. It appears to be possible to configure the GPU to restrict access to addresses within the VRAM pool, but this is not done yet. So for now the GPU will refuse to load if there is no sort of mmu. Once address based limits are supported and tested to confirm that we aren't giving the GPU access to arbitrary memory, this restriction can be lifted Signed-off-by: Rob Clark

drm/msm: COMPILE_TEST support

2014-01-09T19:38:47Z

With a simple stub, we can get COMPILE_TEST support. Signed-off-by: Rob Clark

drm/msm/mdp4: page_flip cleanups/fixes

2013-11-01T16:39:45Z

There were a few potential problems with the original page_flip/vblank code in mdp4_crtc. 1) We need vblank irq for a couple things, both completing flips and updating cursor. We need to keep track of what work is pending so that (for example) a cursor update while we are still waiting for pageflip_cb (ie. pageflip requested from userspace, but still waiting for rendering to complete) would not prematurely trigger event to userspace. 2) A preclose -> pageflip-cancel should not cancel a pageflip that was requested on a different file (ie. non-master closing should not cancel a pending pageflip). With these fixes, we no longer have problems w/ cursor not updating and with occasional hangs with userspace waiting for a pageflip that had been cancelled (launching XBMC from gnome-shell overview mode was a good way to trigger this, but now works reliably).

drm/msm: rework inactive-work

2013-11-01T16:39:45Z

Re-arrange things a bit so that we can get work requested after a bo fence passes, like pageflip, done before retiring bo's. Without any sort of bo cache in userspace, some games can trigger hundred's of transient bo's, which can cause retire to take a long time (5-10ms). Obviously we want a bo cache.. but this cleanup will make things a bit easier for atomic as well and makes things a bit cleaner. Signed-off-by: Rob Clark Acked-by: David Brown

drm/msm: add plane support

2013-11-01T16:39:44Z

Enable using VG1 and VG2 for planes. Currently YUV/CSC or scaling is not enabled, but ARGB and xRGB blending is. Signed-off-by: Rob Clark Acked-by: David Brown

drm/msm: resync generated headers

2013-11-01T16:39:44Z

resync to latest envytools db, fixes a typo: s/mpd4/mdp4/ Signed-off-by: Rob Clark Acked-by: David Brown

drm/msm: Remove iommu include from mdp4_kms.c

2013-09-28T13:17:31Z

The include file has been removed and the file does not need it anyway, so remove it. Fixes a compile error. Signed-off-by: Joerg Roedel Signed-off-by: Rob Clark

drm/msm: convert to drm_bridge

2013-09-02T00:23:35Z

Drop the msm_connector base class, and special calls to base class methods from the encoder, and use instead drm_bridge. This allows for a cleaner division between the hdmi (and in future dsi) blocks, from the mdp block. Signed-off-by: Rob Clark Signed-off-by: Dave Airlie
