2017-10-03drm/i915: Fix DDI PHY init if it was already onImre Deak2-21/+2
The common lane power down flag of a DPIO PHY has a funky semantic: after the initial enabling of the PHY (so from a disabled state) this flag will be clear. It will be set only after the PHY will be used for the first time (for instance due to enabling the corresponding pipe) and then become unused (due to disabling the pipe). During the initial PHY enablement we don't know which of the above phases we are in, so move the check for the flag where this is known, the HW readout code. This is where the rest of lane power down status checks are done anyway. This fixes at least a problem on GLK where after module reloading, the common lane power down flag of PHY1 is set, but the PHY is actually powered-on and properly set up. The GRC readout code for other PHYs will hence think that PHY1 is not powered initially and disable it after the GRC readout. This will cause the AUX power well related to PHY1 to get disabled in a stuck state, timing out when we try to enable it later.

2017-10-02drm/sun4i: hdmi: Disable clks in bind function error path and unbind functionChen-Yu Tsai1-5/+14
The HDMI driver enables the bus and mod clocks in the bind function, but does not disable them if it then bails our due to any errors. Neither does it disable the clocks in the unbind function. Fix this by adding a proper error path to the bind function, and clk_disable_unprepare calls to the unbind function. Also rename the err_cleanup_connector label to err_cleanup_encoder, since it is the encoder that gets cleaned up.

2017-09-26drm/i915: always update ELD connector type after get modesJani Nikula2-5/+17
drm_edid_to_eld() initializes the connector ELD to zero, overwriting the ELD connector type initialized in intel_audio_codec_enable(). If userspace does getconnector and thus get_modes after modeset, a subsequent audio component i915_audio_component_get_eld() call will receive an ELD without the connector type properly set. It's fine for HDMI, but screws up audio for DP. Always set the ELD connector type at intel_connector_update_modes() based on the connector type. We can drop the connector type update from intel_audio_codec_enable(). Credits to Joseph Nuzman <jnuzman@gmail.com> for figuring this out.

This reverts commit bbdf0b2ff32a ("drm/i915/bxt: Disable device ready before shutdown command"). Disable device ready before shutdown command was added previously to avoid a split screen issue seen on dual link DSI panels. As of now, dual link is not supported and will need some rework in the upstream code. For single link DSI panels, the change is not required. This will cause failure in sending SHUTDOWN packet during disable. Hence reverting the change. Will handle the change as part of dual link enabling in upstream.

2017-09-14drm/amdgpu: revert tile table update for olandJean Delvare1-1/+188
Several users have complained that the tile table update broke Oland support. Despite several attempts to fix it, the root cause is still unknown at this point and no solution is available. As it is not acceptable to leave a known regression breaking a major functionality in the kernel for several releases, let's just reverse this optimization for now. It can be implemented again later if and only if the breakage is understood and fixed. As there were no complaints for Hainan so far, only the Oland part of the offending commit is reverted. Optimization is preserved on Hainan, so this commit isn't an actual revert of the original.

2017-09-13mm: treewide: remove GFP_TEMPORARY allocation flagMichal Hocko15-28/+28
GFP_TEMPORARY was introduced by commit e12ba74d8ff3 ("Group short-lived and reclaimable kernel allocations") along with __GFP_RECLAIMABLE. It's primary motivation was to allow users to tell that an allocation is short lived and so the allocator can try to place such allocations close together and prevent long term fragmentation. As much as this sounds like a reasonable semantic it becomes much less clear when to use the highlevel GFP_TEMPORARY allocation flag. How long is temporary? Can the context holding that memory sleep? Can it take locks? It seems there is no good answer for those questions. The current implementation of GFP_TEMPORARY is basically GFP_KERNEL | __GFP_RECLAIMABLE which in itself is tricky because basically none of the existing caller provide a way to reclaim the allocated memory. So this is rather misleading and hard to evaluate for any benefits. I have checked some random users and none of them has added the flag with a specific justification. I suspect most of them just copied from other existing users and others just thought it might be a good idea to use without any measuring. This suggests that GFP_TEMPORARY just motivates for cargo cult usage without any reasoning. I believe that our gfp flags are quite complex already and especially those with highlevel semantic should be clearly defined to prevent from confusion and abuse. Therefore I propose dropping GFP_TEMPORARY and replace all existing users to simply use GFP_KERNEL. Please note that SLAB users with shrinkers will still get __GFP_RECLAIMABLE heuristic and so they will be placed properly for memory fragmentation prevention. I can see reasons we might want some gfp flag to reflect shorterm allocations but I propose starting from a clear semantic definition and only then add users with proper justification. This was been brought up before LSF this year by Matthew [1] and it turned out that GFP_TEMPORARY really doesn't have a clear semantic. It seems to be a heuristic without any measured advantage for most (if not all) its current users. The follow up discussion has revealed that opinions on what might be temporary allocation differ a lot between developers. So rather than trying to tweak existing users into a semantic which they haven't expected I propose to simply remove the flag and start from scratch if we really need a semantic for short term allocations.

2017-09-12drm/amdgpu: revert "fix deadlock of reservation between cs and gpu reset v2"Christian König1-4/+0
This reverts commit 10e709cb296c98424c03408d23e3addeddcd4088. The patch doesn't work at all: 1. The CS can still be blocked because of amdgpu_ctx_add_fence(). 2. The order of submission isn't correct any more. 3. We could end up using freed up memory because we now drop the ctx reference to early. This needs to be fixed cleanly by doing the context handling after the BO handling, but this is a larger task just avoid the obvious crashes for now.

2017-09-12qxl: fix primary surface handlingGerd Hoffmann1-15/+19
The atomic conversion of the qxl driver didn't got the primary surface handling completely right. It works in the common simple cases, but fails for example when changing the display resolution using xrandr or in multihead setups. The rules are simple: There is one primary surface. Before defining a new one you have to destroy the old one. This patch makes qxl_primary_atomic_update() destroy the primary surface before defining a new one. It fixes is_primary flag updates. It adds is_primary checks so we don't try to update the primary surface in case it already has the state we want it being in.

2017-09-08lib/interval_tree: fast overlap detectionDavidlohr Bueso9-28/+33
Allow interval trees to quickly check for overlaps to avoid unnecesary tree lookups in interval_tree_iter_first(). As of this patch, all interval tree flavors will require using a 'rb_root_cached' such that we can have the leftmost node easily available. While most users will make use of this feature, those with special functions (in addition to the generic insert, delete, search calls) will avoid using the cached option as they can do funky things with insertions -- for example, vma_interval_tree_insert_after().

2017-09-06drm/i915: wire up shrinkctl->nr_scannedChris Wilson5-11/+24
shrink_slab() allows us to report back the number of objects we successfully scanned (out of the target shrinkctl->nr_to_scan). As report the number of pages owned by each GEM object as a separate item to the shrinker, we cannot precisely control the number of shrinker objects we scan on each pass; and indeed may free more than requested. If we fail to tell the shrinker about the number of objects we process, it will continue to hold a grudge against us as any objects left unscanned are added to the next reclaim -- and so we will keep on "unfairly" shrinking our own slab in comparison to other slabs.
