* drm/msm: move mdp4 -> mdp/mdp4Rob Clark2014-01-098-3276/+0
| | | | | | | | 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 <robdclark@gmail.com>
* drm/msm: add support for msm8060ab/bstemRob Clark2014-01-091-0/+4
| | | | | | | 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 <robdclark@gmail.com>
* drm/msm: add support for non-IOMMU systemsRob Clark2014-01-091-11/+18
| | | | | | | | | | | | | | | | | | | | | | 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 <robdclark@gmail.com>
* drm/msm: COMPILE_TEST supportRob Clark2014-01-091-2/+0
| | | | | | With a simple stub, we can get COMPILE_TEST support. Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm/mdp4: page_flip cleanups/fixesRob Clark2013-11-013-15/+50
| | | | | | | | | | | | | | | | | | | | | | | 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-workRob Clark2013-11-011-6/+5
| | | | | | | | | | | | 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.

* drm/msm: add plane supportRob Clark2013-11-015-56/+179
| | | | | | | | 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 <robdclark@gmail.com> Acked-by: David Brown <davidb@codeaurora.org>

* drm/msm: Remove iommu include from mdp4_kms.cJoerg Roedel2013-09-281-2/+0
| | | | | | | | 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 <joro@8bytes.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm: convert to drm_bridgeRob Clark2013-09-022-18/+3
| | | | | | | | | | 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 <robdclark@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm/msm: basic KMS driver for snapdragonRob Clark2013-08-247-0/+2065
| | | | | | | | | | | | | | | | | | | | | | | | | The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing.. This patch adds support for mdp4 crtc (including hw cursor), dtv encoder (part of MDP4 block), and hdmi. Signed-off-by: Rob Clark <robdclark@gmail.com>
