2019-09-03drm/msm: drop use of drmP.hSam Ravnborg40-18/+99
Drop the deprecated drmP.h header file, and trim msm_drv.h to the relevant include files. This resulted in a suprisingly many edits as many files relied on headers included via msm_drv.h. But msm_drv.h is not supposed to carry include files it do not need, so the individual files have to include what extra they needs. v2: - Rebased on top of https://gitlab.freedesktop.org/drm/msm.git msm-next Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Rob Clark <robdclark@gmail.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Jordan Crouse <jcrouse@codeaurora.org> Cc: Jeykumar Sankaran <jsanka@codeaurora.org> Cc: Bruce Wang <bzwang@chromium.org> Cc: Shayenne Moura <shayenneluzmoura@gmail.com> Cc: Mamta Shukla <mamtashukla555@gmail.com> Cc: Jonathan Marek <jonathan@marek.ca> Cc: Carsten Behling <carsten.behling@googlemail.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Paul Kocialkowski <paul.kocialkowski@bootlin.com> Cc: Sibi Sankar <sibis@codeaurora.org> Cc: Todor Tomov <todor.tomov@linaro.org> Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190804065551.GA5211@ravnborg.org

2019-08-01drm: msm: Fix add_gpu_componentsJeffrey Hugo1-1/+2
add_gpu_components() adds found GPU nodes from the DT to the match list, regardless of the status of the nodes. This is a problem, because if the nodes are disabled, they should not be on the match list because they will not be matched. This prevents display from initing if a GPU node is defined, but it's status is disabled. Fix this by checking the node's status before adding it to the match list.

2019-08-01drm/msm: add support for per-CRTC max_vblank_count on mdp5Brian Masney2-2/+16
The mdp5 drm/kms driver currently does not work on command-mode DSI panels due to 'vblank wait timed out' errors. This causes a latency of seconds, or tens of seconds in some cases, before content is shown on the panel. This hardware does not have the something that we can use as a frame counter available when running in command mode, so we need to fall back to using timestamps by setting the max_vblank_count to zero. This can be done on a per-CRTC basis, so the convert mdp5 to use drm_crtc_set_max_vblank_count(). This change was tested on a LG Nexus 5 (hammerhead) phone.

[subject was: drm/msm: shake fist angrily at dma-mapping] So, using dma_sync_* for our cache needs works out w/ dma iommu ops, but it falls appart with dma direct ops. The problem is that, depending on display generation, we can have either set of dma ops (mdp4 and dpu have iommu wired to mdss node, which maps to toplevel drm device, but mdp5 has iommu wired up to the mdp sub-node within mdss).

https://gitlab.freedesktop.org/drm/msm into drm-next + usual progress on cleanups + dsi vs EPROBE_DEFER fixes + msm8998 (snapdragon 835 support) + a540 gpu support (mesa support already landed) + dsi, dsi-phy support + mdp5 and dpu interconnect (bus/memory scaling) support + initial prep work for per-context pagetables (at least the parts that don't have external dependencies like iommu/arm-smmu) There is one more patch for fixing DSI cmd mode panels (part of a set of patches to get things working on nexus5), but it would be conflicty with 1cff7440a86e04a613665803b42034 in drm-next without rebasing or back-merge, and since it doesn't conflict with anything in msm-next, I think it best if Sean merges that through drm-mix-fixes instead. (In other news, I've been making some progress w/ getting efifb working properly on sdm850 laptop without horrible hacks, and drm/msm + clk stuff not totally falling over when bootloader enables display and things are already running when driver probes.. but not quite ready yet, hopefully we can post some of that for 5.4.. should help for both the sdm835 and sdm850 laptops.)

2019-06-20drm/msm: Depopulate platform on probe failureSean Paul1-3/+11
add_display_components() calls of_platform_populate, and we depopluate on pdev remove, but not when probe fails. So if we get a probe deferral in one of the components, we won't depopulate the platform. This causes the core to keep references to devices which should be destroyed, which causes issues when those same devices try to re-initialize on the next probe attempt. I think this is the reason we had issues with the gmu's device-managed resources on deferral (worked around in commit 94e3a17f33a5).

The interconnect API provides an interface for consumer drivers to express their bandwidth needs in the SoC. This data is aggregated and the on-chip interconnect hardware is configured to the most appropriate power/performance profile. Use the API to configure the interconnects and request bandwidth between DDR and the display hardware (MDP port(s) and rotator downscaler). v2: update the path names to be consistent with dpu, handle the NULL path case, updated commit msg from Georgi. v3: split out icc setup into it's own function, and rework logic slightly so no interconnect paths is not fatal.

The interconnect framework is designed to provide a standard kernel interface to control the settings of the interconnects on a SoC. The interconnect API uses a consumer/provider-based model, where the providers are the interconnect buses and the consumers could be various drivers. MDSS is one of the interconnect consumers which uses the interconnect APIs to get the path between endpoints and set its bandwidth requirement for the given interconnected path.
