Pretty small pull this time around for msm. Adds some useful debugfs I'd been carrying around on a branch for a while, plus few fixes. And Kconfig update for the great ARCH_MSM -> ARCH_QCOM split. * 'msm-next' of git://people.freedesktop.org/~robclark/linux: drm/msm: use correct gfp flag for vram allocation drm/msm/mdp5: fix error return value drm/msm: remove redundant private plane cleanup drm/msm: add perf logging debugfs drm/msm: add rd logging debugfs drm/msm: update for ARCH_MSM -> ARCH_QCOM drm/msm/hdmi: use gpio and HPD polling drm/msm/mdp5: fix crash in error/unload paths

The drm core shouldn't depend upon any helpers, and we make sure this doesn't accidentally happen by moving them into the helper-only drm_kms_helper.ko module. v2: Don't break the build for vmwgfx, spotted by Matt. v3: Unbreak the depency loop around CONFIG_FB (not actually a loop since it involves select).

After the split-out of crtc locks from the big mode_config.mutex there's still two major areas it protects: - Various connector probe states, like connector->status, EDID properties, probed mode lists and similar information. - The links from connector->encoder and encoder->crtc and other modeset-relevant connector state (e.g. properties which control the panel fitter). The later is used by modeset operations. But they don't really care about the former since it's allowed to e.g. enable a disconnected VGA output or with a mode not in the probed list. Thus far this hasn't been a problem, but for the atomic modeset conversion Rob Clark needs to convert all modeset relevant locks into w/w locks. This is required because the order of acquisition is determined by how userspace supplies the atomic modeset data. This has run into troubles in the detect path since the i915 load detect code needs _both_ protections offered by the mode_config.mutex: It updates probe state and it needs to change the modeset configuration to enable the temporary load detect pipe. The big deal here is that for the probe/detect users of this lock a plain mutex fits best, but for atomic modesets we really want a w/w mutex. To fix this lets split out a new connection_mutex lock for the modeset relevant parts. For simplicity I've decided to only add one additional lock for all connector/encoder links and modeset configuration states. We have piles of different modeset objects in addition to those (like bridges or panels), so adding per-object locks would be much more effort. Also, we're guaranteed (at least for now) to do a full modeset if we need to acquire this lock. Which means that fine-grained locking is fairly irrelevant compared to the amount of time the full modeset will take. I've done a full audit, and there's just a few things that justify special focus: - Locking in drm_sysfs.c is almost completely absent. We should sprinkle mode_config.connection_mutex over this file a bit, but since it already lacks mode_config.mutex this patch wont make the situation any worse. This is material for a follow-up patch. - omap has a omap_framebuffer_flush function which walks the connector->encoder->crtc links and is called from many contexts. Some look like they don't acquire mode_config.mutex, so this is already racy. Again fixing this is material for a separate patch. - The radeon hot_plug function to retrain DP links looks at connector->dpms. Currently this happens without any locking, so is already racy. I think radeon_hotplug_work_func should gain mutex_lock/unlock calls for the mode_config.connection_mutex. - Same applies to i915's intel_dp_hot_plug. But again, this is already racy. - i915 load_detect code needs to acquire this lock. Which means the w/w dance due to Rob's work will be nicely contained to _just_ this function. I've added fixme comments everywhere where it looks suspicious but in the sysfs code. After a quick irc discussion with Dave Airlie it sounds like the lack of locking in there is due to sysfs cleanup fun at module unload. v1: original (only compile tested) v2: missing mutex_init(), etc (from Rob Clark) v3: i915 needs more care in the conversion: - Protect the edp pp logic with the connection_mutex. - Use connection_mutex in the backlight code due to get_pipe_from_connector. - Use drm_modeset_lock_all in suspend/resume paths. - Update lock checks in the overlay code.

If we continue to use bitmask for type, we will quickly run out of room to add new types. Split this up so existing part of bitmask range continues to function as before, but reserve a chunk of the remaining space for an integer type-id. Wrap this all up in some type-check helpers to keep the backwards-compat uglyness contained. Signed-off-by:

spice-server and downstream code expect that the primary surface will always have surface_id = 0, while in reality, once allocated, the surface_id in qxl.ko is NEVER 0. In a dual head environment, all monitors render portions of the primary surface. However, when the monitor config events are generated and sent, the primary surface is only mapped to the correct identifier (i.e. 0) for the primary head (where crtc index is 0). The fix is to look at the "primary" flag in the bo and always use id 0, irrespective of which head is being configured. [airlied: qxl hw really needs to be fixed to scanout surfaces] Signed-off-by: -

DCE-4/5/6 can't support more than 12 bpc deep color over hdmi, so clamp to 12 bpc when a hdmi deep color capable display is connected. This even makes sense on DCE-8+, which could do up to 16 bpc, as driving with more than 12 bpc would only waste video bandwidth as long as we don't support framebuffers with more than 12 bpc depth. On pre-DCE4 we clamp hdmi bit depth to 8 bpc, as those asics don't support hdmi deep color. Signed-off-by:
