If a page isn't allocated as __GFP_MOVEABLE it won't move around, so no need to grab a reference to lock it into place. Discovered while reviewing page allocation handling in i915 gem. Acked-by:

While discussing/reviewing __GFP_MOVEABLE behaviour and interactions with our various page allocations on irc Chris brought up that the scratch page isn't allocated as moveable, but we still grab/put a reference to lock it in place. Which is unecessary. So drop that. Acked-by:

Factor out a piece of code from intel_pipe_set_base() that updates the pipe size and adjust fitter. This will help refactor the update primary plane path. v2: use struct intel_crtc as argument to intel_update_pipe_size() v3: use 'crtc' as argument name Signed-off-by:

Optimize code avoiding helding dev mutex if old fb and current fb are the same. v2: take Ville's comments - move comment along with the pin_and_fence call - check for error before calling i915_gem_track_fb - move old_obj != obj to an upper if condition Signed-off-by:

As a preparation for atomic updates we need to split the code to check everything we are going to commit first. This patch starts the work to split intel_primary_plane_setplane() into check() and commit() parts. More work is expected on this to get a better split of the two steps. Ideally the commit() step should never fail. Signed-off-by:

Due to the upcoming atomic modesetting feature we need to separate some update functions into a check step that can fail and a commit step that should, ideally, never fail. The commit part can still fail, but that should be solved in another upcoming patch. Signed-off-by:

Now that vlv has runtime pm we kinda should check for that like on the pch split platforms. Looks like this was simply lost in the vlv rpm enabling. Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Reviewed-by:

Use full PPGTT as the default option in gen7. Note that aliasing PPGTT is the default option for gen8 (see HAS_PPGTT) since we're still fighting troubles around context switching and execlists. This may well come back to bite me later. Signed-off-by:

If we believe that the device can cross cache domains in its prefetcher (i.e. we allow neighbouring pages in different domains), we don't supply a color_adjust callback. Use the presence of this callback to better determine when we should be verifying that the GTT space we just used is valid. v2: Remove the superfluous struct drm_device function param as well.

gen6 and earlier conflate address space selection (ppgtt vs ggtt) with the security bit (i.e. only privileged batches were allowed to run from ggtt). From Haswell only, you are able to select the security bit separate from the address space - and we always requested to use ppgtt. This breaks the golden render state batch execution with full-ppgtt as that is only present in the global GTT and more generally any secure batch that is not colocated in the ppgtt and ggtt. So we need to disable the use of the ppgtt selector bit for secure batches, or else we hang immediately upon boot and thence after every GPU reset... v2: Only HSW differentiates between secure dispatch and ggtt, so simply ignore the differentiation and always use secure==ggtt.

Before we process the final unbind on an object and move it to the unbound list, it is semantically cleaner if there are no more active references to the object. (An active reference would imply that it was still being accessed by the GPU after it became inaccessible.) The caveat is that all callsites must be prepared for the object to disappeared during the unbind - i.e. they must hold their own reference. Signed-off-by:

Due to the lazy retirement semantics, even though we have unbound an object, it may still hold onto an active reference. So in the debug code, play safe. v2: Export i915_gem_shrink() rather than opencoding it. Signed-off-by:

eDP panels are generally designed to support only a single clock and lane configuration. commit 56071a20 Author: Jani Nikula <jani.nikula@intel.com> Date: Tue May 6 14:56:52 2014 +0300 drm/i915: use lane count and link rate from VBT as minimums for eDP should have started using the optimal link parameters for eDP panels. Turns out a certain other OS uses DPCD instead of VBT, which means trusting VBT on this may not be so reliable after all. Follow suit.

830 is very unhappy of the watermark value is too low (indicating a very high watermark in fact, ie. memory fetch will occur with an almost full FIFO). Limit the watermark value to at least 8 cache lines. That also matches the burst size we use on most platforms. BSpec seems to indicate we should limit the watermark to 'burst size + 1'. But on gen4 we already use a hardcoded 8 as the watermark value (as the spec says we should), so just use 8 as the limit on gen2/3 as well. Signed-off-by:

The spec says: "For the correct operation of the muxed DVO pins (GDEVSELB/ I2Cdata, GIRDBY/I2CClk) and (GFRAMEB/DVI_Data, GTRDYB/DVI_Clk): Bit 31 (DPLL VCO Enable) and Bit 30 (2X Clock Enable) must be set to “1” in both the DPLL A Control Register (06014h-06017h) and DPLL B Control Register (06018h-0601Bh)." The pipe A and B force quirks take care of DPLL_VCO_ENABLE, so we just need a bit of special care to handle DPLL_DVO_2X_MODE. v2: Recompute num_dvo_pipes on the spot, use PIPE_A/PIPE_B instead of pipe/!pipe for the register offsets in disable (Daniel) Add a comment about the ordering in enable and another one about filtering out the DVO 2x bit in state readout Signed-off-by:

While zone->name is currently hard coded, the call to kobject_init_and_add() should follow the more defensive argument list usage (as already done in other places in ttm_memory.c) where "%s" is used instead of directly passing in a variable as a format string. Signed-off-by:

In order to support the "enable GPIO" available in many panel devices, this commit adds a proper devicetree binding. By providing an enable GPIO in the devicetree, the driver can now turn off and on the panel device, and/or the backlight device. Both the backlight and the GPIO are optional properties. Tested-by:

The current backlight support is broken; the driver expects a backlight-class in the panel devicetree node. Fix this by implementing it properly, getting an optional backlight from a phandle. This shouldn't cause any backward-compatibility DT issue because the current implementation doesn't work and is not even documented. Tested-by:

The current error path calls tilcdc_unload() in case of an error to release the resources. However, this is wrong because not all resources have been allocated by the time an error occurs in tilcdc_load(). To fix it, this commit adds proper labels to bail out at the different stages in the load function, and release only the resources actually allocated. Tested-by:
