git://anongit.freedesktop.org/drm-intel into drm-next As promised, piles of prep work all around: - drm_atomic_state rework, prep for nonblocking commit helpers - fence patches from Gustavo and Christian to prep for atomic fences and some cool work in ttm/amdgpu from Christian - drm event prep for both nonblocking commit and atomic fences - Gustavo seems on a crusade against the non-kms-native version of the vblank functions. - prep work from Boris to nuke all the silly ->best_encoder implementations we have (we really only need that for truly dynamic cases like dvi-i vs dvi-d or dp mst selecting the right transcoder on intel) - prep work from Laurent to rework the format handling functions - and few small things all over * tag 'topic/drm-misc-2016-06-07' of git://anongit.freedesktop.org/drm-intel: (47 commits) drm/dsi: Implement set tear scanline drm/fb_cma_helper: Implement fb_mmap callback drm/qxl: Remove useless drm_fb_get_bpp_depth() call drm/ast: Remove useless drm_fb_get_bpp_depth() call drm/atomic: Fix remaining places where !funcs->best_encoder is valid drm/core: Change declaration for gamma_set.

2016-06-07drm/fb_cma_helper: Implement fb_mmap callbackRobin Murphy
In the absence of an fb_mmap callback, the fbdev code falls back to a naive implementation which relies upon the DMA address being the same as the physical address, and the buffer being physically contiguous from there. Whilst this often holds for standard CMA allocations via the platform's regular DMA ops, if the allocation is provided by an IOMMU then such assumptions can fall apart spectacularly. To resolve this, reroute the fb_mmap call to the appropriate DMA API implementation, as per the other cma_helper calls.

2016-06-07drm/i915: only disable memory self-refresh on GMCHDavid Weinehall
The atomic version of intel_pre_plane_update did not check for HAS_GMCH_DISPLAY before calling intel_set_memory_cxsr(). While this doesn't cause any issues on its own (it will return without doing anything if the hardware doesn't have the required feature), the drm_wait_one_vblank() that is needed if memory self-refresh is disabled introduces an unnecessary delay in the suspend path. In cases where i915 is on the critical path it means that we slow down suspend by 16.8ms on platforms that don't need to disable memory self-refresh.

Apparently some CHV boards failed to hook up the port presence straps for HDMI ports as well (earlier we assumed this problem only affected eDP ports). So let's check the VBT in addition to the strap, and if either one claims that the port is present go ahead and register the relevant connector. While at it, change port D to register DP before HDMI as we do for ports B and C since commit 457c52d87e5d ("drm/i915: Only ignore eDP ports that are connected") Also print a debug message when we register a HDMI connector to aid in diagnosing missing/incorrect ports. We already had such a print for DP/eDP. v2: Improve the comment in the code a bit, note the port D change in the commit message Cc: Radoslav Duda <radosd@radosd.com> Tested-by: Radoslav Duda <radosd@radosd.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96321 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1464945463-14364-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-06-07drm/atomic: Fix remaining places where !funcs->best_encoder is validBoris Brezillon
Adapt drm_pick_crtcs() and update_connector_routing() to fallback to drm_atomic_helper_best_encoder() if funcs->best_encoder() is NULL so that DRM drivers can leave this hook unassigned if they know they want to use drm_atomic_helper_best_encoder().

2016-06-07drm/omapdrm: Implement gamma_lut atomic crtc propertiesJyri Sarha
Implement gamma_lut atomic crtc properties, set crtc gamma size to 256 for all crtcs and use drm_atomic_helper_legacy_gamma_set() as gamma_set func. The tv-out crtc has 1024 element gamma table (with 10bit precision) in HW, but current Xorg server does not accept anything else but 256 elements so that is used for all CRTCs. The dss dispc API converts table of any length for HW and uses linear interpolation in the process. The default gamma table is restored if gamma_lut property is deleted.

2016-06-07drm/omapdrm: Workaround for errata i734 (LCD1 Gamma) in DSS dispcJyri Sarha
Workaround for errata i734 in DSS dispc - LCD1 Gamma Correction Is Not Working When GFX Pipe Is Disabled For gamma tables to work on LCD1 the GFX plane has to be used at least once after DSS HW has come out of reset. The workaround sets up a minimal LCD setup with GFX plane and waits for one vertical sync irq before disabling the setup and continuing with the context restore. The physical outputs are gated during the operation. For details see: OMAP543x Multimedia Device Silicon Revision 2.0 Silicon Errata Literature Number: SWPZ037E Or some other relevant errata document for the DSS IP version.

2016-06-07drm/omapdrm: Add gamma table support to DSS dispcJyri Sarha
Add gamma table support to DSS dispc. DSS driver initializes the default gamma table at component bind time and holds a copy of all gamma tables in its internal data structure. Each call to dispc_mgr_set_gamma() updates the internal table and triggers write to the HW, if it is enabled. The tables are restored to HW in PM resume callback. The drivers internal data structure match the HW tables in size and in number of significant bits per color component. The dispc_mgr_set_gamma() converts the size of any given table for the internal data structure using linear interpolation. Default gamma table is restored if NULL is given in place of gamma lut. dispc_mgr_gamma_size() gives HW gamma table size for the channel and returns 0 if gamma table is not supported by the HW or the DSS driver.

Change return value to int to propagate errors from gamma_set, and remove start parameter. Updates always use the full size, and some drivers even ignore the start parameter altogether. This is needed for atomic drivers, where an atomic commit can fail with -EINTR or -ENOMEM and should be restarted.

2016-06-07drm/i915/guc: disable GuC submission earlier during GuC (re)loadDave Gordon
When resetting and reloading the GuC, the GuC submission management code also needs to destroy and recreate the GuC client(s). Currently this is done by a separate call from the GuC loader, but really, it's just an internal detail of the submission code. So here we remove the call from the loader (which is too late, really, because the GuC has already been reloaded at this point) and put it into guc_submission_init() instead. This means that any preexisting client is destroyed *before* the GuC (re)load and then recreated after, iff the firmware was successfully loaded. If the GuC reload fails, we don't recreate the client, so fallback to execlists mode (if active) won't leak the client object (previously, the now-unusable client would have been left allocated, and leaked if the driver were unloaded).

2016-06-07drm/i915/guc: fix GuC loading/submission checkDave Gordon
The last stage of the GuC loader also sanitises the GuC submission settings, so should be called unconditionally (even on platforms without a GuC) to ensure consistent settings; in particular, this prevents any attempt to use GuC submission on GuCless platforms! Also fix error path handling and clarify DRM_INFO fallback message.
