2017-05-29drm/dp: start a DPCD based DP sink/branch device quirk databaseJani Nikula1-0/+32
Face the fact, there are Display Port sink and branch devices out there in the wild that don't follow the Display Port specifications, or they have bugs, or just otherwise require special treatment. Start a common quirk database the drivers can query based on the DP device identification. At least for now, we leave the workarounds for the drivers to implement as they see fit. For starters, add a branch device that can't handle full 24-bit main link Mdiv and Ndiv main link attributes properly. Naturally, the workaround of reducing main link attributes for all devices ended up in regressions for other devices.

2017-05-08mm, vmalloc: use __GFP_HIGHMEM implicitlyMichal Hocko1-6/+3
__vmalloc* allows users to provide gfp flags for the underlying allocation. This API is quite popular $ git grep "=[[:space:]]__vmalloc\|return[[:space:]]*__vmalloc" | wc -l 77 The only problem is that many people are not aware that they really want to give __GFP_HIGHMEM along with other flags because there is really no reason to consume precious lowmemory on CONFIG_HIGHMEM systems for pages which are mapped to the kernel vmalloc space. About half of users don't use this flag, though. This signals that we make the API unnecessarily too complex. This patch simply uses __GFP_HIGHMEM implicitly when allocating pages to be mapped to the vmalloc space. Current users which add __GFP_HIGHMEM are simplified and drop the flag.

2017-04-06drm: of: introduce drm_of_find_panel_or_bridgeRob Herring1-0/+13
Many drivers have a common pattern of searching the OF graph for either an attached panel or bridge and then finding the DRM struct for the panel or bridge. Also, most drivers need to handle deferred probing when the DRM device is not yet instantiated.

2017-04-06drm/atomic: Unify conflicting encoder handling.Maarten Lankhorst1-2/+0
Currently we use a flag to change behavior in atomic commit whether a conflicting encoder should be enabled or disabled. This is used for the legacy set_config helper, which disables connectors that have a conflicting encoder but not part of the active crtc list. There's no need for this to be handled in atomic commit, it could be done in the set_config helper instead. This will let the atomic check function reject any conflicting encoders, while set_config can disable conflicting crtc's. This makes it possible to recalculate the changed flags in 1 loop.

2017-04-06drm/atomic: Acquire connection_mutex lock in drm_helper_probe_single_connector_modes, v4.Maarten Lankhorst3-0/+45
mode_valid() called from drm_helper_probe_single_connector_modes() may need to look at connector->state because what a valid mode is may depend on connector properties being set. For example some HDMI modes might be rejected when a connector property forces the connector into DVI mode. Some implementations of detect() already lock all state, so we have to pass an acquire_ctx to them to prevent a deadlock. This means changing the function signature of detect() slightly, and passing the acquire_ctx for locking multiple crtc's. For the callbacks, it will always be non-zero. To allow callers not to worry about this, drm_helper_probe_detect_ctx is added which might handle -EDEADLK for you. Changes since v1: - Always set ctx parameter. Changes since v2: - Always take connection_mutex when probing. Changes since v3: - Remove the ctx from intel_dp_long_pulse, and add WARN_ON(!connection_mutex) (danvet) - Update docs to clarify the locking situation.

Atomic helpers really want this instead of the hacked-up legacy backoff trick, which unfortunately prevents drivers from using their own private drm_modeset_locks. Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which don't yet use the new atomic color mgmt/gamma table stuff. Would be nice if they could switch over and just hook up drm_atomic_helper_legacy_gamma_set() instead.

2017-04-04drm: document drm_ioctl.[hc]Daniel Vetter1-15/+101
Also unify/merge with the existing stuff. I was a bit torn where to put this, but in the end I decided to put all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we have a bit a split with the other uapi related stuff used internally, like drm_file.[hc], but I think overall this makes more sense. If it's too confusing we can always add more cross-links to make it more discoverable. But the auto-sprinkling of links kernel-doc already does seems sufficient. Also for prettier docs and more cross-links, switch the internal defines over to an enum, as usual. v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a bit more drive-by polish. v3: Fix typo, spotted by xerpi on irc (Sergi). v4: Add missing space in comment (Neil).

2017-03-27drm/atomic: Introduce drm_atomic_helper_shutdownDaniel Vetter1-0/+1
The trouble here is that it does multiple atomic commits under one drm_modeset_lock_all, which breaks the behind-the-scenes acquire context magic that function pulls off. It's much better to have one overall atomic commit. That we still have multiple atomic commits prevents us from adding some pretty useful debug checks to the atomic machinery. Hence it is really a bad idea to call the legacy drm_crtc_force_disable_all() function. There's 2 atomic drivers using this still, nouveau and tinydrm. To fix this, introduce a new drm_atomic_helper_shutdown() by extracting the code from i915. While at it improve kernel-doc and catch future offenders by sprinkling a WARN_ON into the legacy function. We should probably move those into the legacy modeset helpers, too ... v2: Make it compile on arm drivers too (Noralf). v3: Correct kerneldoc to point at _disable_all().

2017-03-22drm/dp: Split drm_dp_mst_allocate_vcpiPandiyan, Dhinakaran1-1/+2
drm_dp_mst_allocate_vcpi() apart from setting up the vcpi structure, also finds if there are enough slots available. This check is a duplicate of that implemented in drm_dp_mst_find_vcpi_slots(). Let's move this check out and reuse the existing drm_dp_mst_find_vcpi_slots() function to check if there are enough vcpi slots before allocating them. This brings the check to one place. Additionally drivers that will use MST state tracking for atomic modesets can use the atomic version of find_vcpi_slots() and reuse drm_dp_mst_allocate_vcpi() Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1489648231-30700-4-git-send-email-dhinakaran.pandiyan@intel.com

So, let's make that check obvious and remove avail_slots. While at it, make debug messages more descriptive.

2017-03-22drm/dp: Kill total_pbn and total_slots in struct drm_dp_mst_topology_mgrPandiyan, Dhinakaran1-8/+1
The total vcpi time slots is always 63 and does not depend on the link BW, remove total_slots from MST topology manager struct. The next change is to remove total_pbn which is hardcoded to 2560. The total PBN that the topology manager allocates from depends on the link rate and is not a constant. So, fix this by removing the total_pbn member itself.
