Don't allow conversion from arbitraty encoder types to a digital port. Calling enc_to_dig_port() with the wrong encoder may seem far fetched, but certain paths of the ddi code may be called with hasell's analog encoder and the conversion is wrong for DP mst encoders too, so safe guard against it. v2: Warn if encoder type is unknown and device is not DDI.

This patch makes the I915_PARAM_HAS_EXEC_CONSTANTS getparam return 0 (indicating the optional feature is not supported), and makes execbuf always return -EINVAL if the flags are used. Apparently, no userspace ever shipped which used this optional feature: I checked the git history of Mesa, xf86-video-intel, libva, and Beignet, and there were zero commits showing a use of these flags. Kernel commit 72bfa19c apparently introduced the feature prematurely. According to Chris, the intention was to use this in cairo-drm, but "the use was broken for gen6", so I don't think it ever happened. 'relative_constants_mode' has always been tracked per-device, but this has actually been wrong ever since hardware contexts were introduced, as the INSTPM register is saved (and automatically restored) as part of the render ring context. The software per-device value could therefore get out of sync with the hardware per-context value. This meant that using them is actually unsafe: a client which tried to use them could damage the state of other clients, causing the GPU to interpret their BO offsets as absolute pointers, leading to bogus memory reads. These flags were also never ported to execlist mode, making them no-ops on Gen9+ (which requires execlists), and Gen8 in the default mode. On Gen8+, userspace can write these registers directly, achieving the same effect. On Gen6-7.5, it likely makes sense to extend the command parser to support them. I don't think anyone wants this on Gen4-5. Based on a patch by Dave Gordon. v3: Return -ENODEV for the getparam, as this is what we do for other obsolete features. Suggested by Chris Wilson.

At least a ParadTech PS175 LSPCON chip/firmware uses long instead of short pulses to signal output unplug/plug events. This is contrary to how branch devices normally work which use short HPD signaling. This chip will also switch to LS mode after an unplug event, which could be the consequence of the long HPD signaling semantics and an effort to save power automatically. Because of this we'll fail to do AUX and detect the output after a replug event. To fix this make sure we are in PCON mode during connector detection. v2: - Switch the mode in the proper spot.

A request is assigned a global seqno only when it is on the hardware execution queue. The global seqno can be used to maintain a list of requests on the same engine in retirement order, for example for constructing a priority queue for waiting. Prior to its execution, or if it is subsequently removed in the event of preemption, its global seqno is zero. As both insertion and removal from the execution queue may operate in IRQ context, it is not guarded by the usual struct_mutex BKL. Instead those relying on the global seqno must be prepared for its value to change between reads. Only when the request is complete can the global seqno be stable (due to the memory barriers on submitting the commands to the hardware to write the breadcrumb, if the HWS shows that it has passed the global seqno and the global seqno is unchanged after the read, it is indeed complete).

Replace the global device seqno with one for each engine, and account for in-flight seqno on each separately. This is consistent with dma-fence as each timeline has separate fence-contexts for each engine and a seqno is only ordered within a fence-context (i.e. seqno do not need to be ordered wrt to other engines, just ordered within a single engine). This is required to enable request rewinding for preemption on individual engines (we have to rewind the global seqno to avoid overflow, and we do not have to rewind all engines just to preempt one.) v2: Rename active_seqno to inflight_seqnos to more clearly indicate that it is a counter and not equivalent to the existing seqno.

When dma_fence_signal() is called, it sets a flag to indicate the fence is complete. Before the dma_fence is signaled, the seqno check will first be passed. During an unlocked check (such as inside a waiter), it is possible for the fence to be signaled even though the seqno has been reset (by engine wraparound). In this case the waiter will be kicked, but for an extra layer of protection we can check the persistent signaled bit from the fence. Signed-off-by:

Geminilake has a third sprite plane (or fourth universal plane) that is independent from the cursor. Make sure that for_each_plane_id_on_crtc() is aware of that extra plane so that the watermark code takes it into account.

Testing with concurrent GGTT accesses no longer show the coherency problems from yonder, commit 5bab6f60 ("drm/i915: Serialise updates to GGTT with access through GGTT on Braswell"). My presumption is that the root cause was more likely fixed by commit 3b5724d7 ("drm/i915: Wait for writes through the GTT to land before reading back"), along with the use of WC updates to the global gTT in commit 8448661d ("drm/i915: Convert clflushed pagetables over to WC maps". Given that the original symptoms can no longer be reproduced, time to remove the workaround. Testcase: igt/gem_concurrent_blit Signed-off-by:

Right now this is just leaving a lot of spam in dmesg that makes real issues more difficult to debug. As well (as noted by the comment right above the DRM_DEBUG_KMS() call) this is normal behavior when there's nothing connected to the DisplayPort connector. Signed-off-by:

Setting retire=true is identical to using origin=ORIGIN_CS, so make the same simplification to intel_fb_obj_flush() as already employed for intel_fb_obj_invalidate(). Signed-off-by:
