2016-03-01drm/i915: Pass 90/270 vs. 0/180 rotation info for ↵Ville Syrjälä3-30/+63
intel_gen4_compute_page_offset() The page aligned surface address calculation needs to know which way things are rotated. The contract now says that the caller must pass the rotate x/y coordinates, as well as the tile_height aligned stride in the tile_height direction. This will make it fairly simple to deal with 90/270 degree rotation on SKL+ where we have to deal with the rotated view into the GTT. v2: Pass rotation instead of bool even thoughwe only care about 0/180 vs. 90/270 v3: Introduce intel_tile_dims(), and don't mix up different units so much v4: Unconfuse bytes vs. pixels even more Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1455569699-27905-4-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2016-03-01drm/i915: Execlists small cleanups and micro-optimisationsTvrtko Ursulin2-103/+114
Assorted changes in the areas of code cleanup, reduction of invariant conditional in the interrupt handler and lock contention and MMIO access optimisation. * Remove needless initialization. * Improve cache locality by reorganizing code and/or using branch hints to keep unexpected or error conditions out of line. * Favor busy submit path vs. empty queue. * Less branching in hot-paths. v2: * Avoid mmio reads when possible. (Chris Wilson) * Use natural integer size for csb indices. * Remove useless return value from execlists_update_context. * Extract 32-bit ppgtt PDPs update so it is out of line and shared with two callers. * Grab forcewake across all mmio operations to ease the load on uncore lock and use chepear mmio ops. v3: * Removed some more pointless u8 data types. * Removed unused return from execlists_context_queue. * Commit message updates. v4: * Unclumsify the unqueue if statement. (Chris Wilson) * Hide forcewake from the queuing function. (Chris Wilson) Version 3 now makes the irq handling code path ~20% smaller on 48-bit PPGTT hardware, and a little bit less elsewhere. Hot paths are mostly in-line now and hammering on the uncore spinlock is greatly reduced together with mmio traffic to an extent. Benchmarking with "gem_latency -n 100" (keep submitting batches with 100 nop instruction) shows approximately 4% higher throughput, 2% less CPU time and 22% smaller latencies. This was on a big-core while small-cores could benefit even more. Most likely reason for the improvements are the MMIO optimization and uncore lock traffic reduction. One odd result is with "gem_latency -n 0" (dispatching empty batches) which shows 5% more throughput, 8% less CPU time, 25% better producer and consumer latencies, but 15% higher dispatch latency which is yet unexplained.

2016-02-29drm/i915: Add two-stage ILK-style watermark programming (v11)Matt Roper6-58/+244
In addition to calculating final watermarks, let's also pre-calculate a set of intermediate watermark values at atomic check time. These intermediate watermarks are a combination of the watermarks for the old state and the new state; they should satisfy the requirements of both states which means they can be programmed immediately when we commit the atomic state (without waiting for a vblank). Once the vblank does happen, we can then re-program watermarks to the more optimal final value. v2: Significant rebasing/rewriting. v3: - Move 'need_postvbl_update' flag to CRTC state (Daniel) - Don't forget to check intermediate watermark values for validity (Maarten) - Don't due async watermark optimization; just do it at the end of the atomic transaction, after waiting for vblanks. We do want it to be async eventually, but adding that now will cause more trouble for Maarten's in-progress work. (Maarten) - Don't allocate space in crtc_state for intermediate watermarks on platforms that don't need it (gen9+). - Move WaCxSRDisabledForSpriteScaling:ivb into intel_begin_crtc_commit now that ilk_update_wm is gone. v4: - Add a wm_mutex to cover updates to intel_crtc->active and the need_postvbl_update flag. Since we don't have async yet it isn't terribly important yet, but might as well add it now. - Change interface to program watermarks. Platforms will now expose .initial_watermarks() and .optimize_watermarks() functions to do watermark programming. These should lock wm_mutex, copy the appropriate state values into intel_crtc->active, and then call the internal program watermarks function. v5: - Skip intermediate watermark calculation/check during initial hardware readout since we don't trust the existing HW values (and don't have valid values of our own yet). - Don't try to call .optimize_watermarks() on platforms that don't have atomic watermarks yet. (Maarten) v6: - Rebase v7: - Further rebase v8: - A few minor indentation and line length fixes v9: - Yet another rebase since Maarten's patches reworked a bunch of the code (wm_pre, wm_post, etc.) that this was previously based on. v10: - Move wm_mutex to dev_priv to protect against racing commits against disjoint CRTC sets. (Maarten) - Drop unnecessary clearing of cstate->wm.need_postvbl_update (Maarten) v11: - Now that we've moved to atomic watermark updates, make sure we call the proper function to program watermarks in {ironlake,haswell}_crtc_enable(); the failure to do so on the previous patch iteration led to us not actually programming the watermarks before turning on the CRTC, which was the cause of the underruns that the CI system was seeing. - Fix inverted logic for determining when to optimize watermarks. We were needlessly optimizing when the intermediate/optimal values were the same (harmless), but not actually optimizing when they differed (also harmless, but wasteful from a power/bandwidth perspective).

2016-02-25drm/i915: Kill off intel_crtc->atomic.wait_vblank, v6.Maarten Lankhorst3-25/+90
Currently we perform our own wait in post_plane_update, but the atomic core performs another one in wait_for_vblanks. This means that 2 vblanks are done when a fb is changed, which is a bit overkill. Merge them by creating a helper function that takes a crtc mask for the planes to wait on. The broadwell vblank workaround may look gone entirely but this is not the case. pipe_config->wm_changed is set to true when any plane is turned on, which forces a vblank wait. Changes since v1: - Removing the double vblank wait on broadwell moved to its own commit. Changes since v2: - Move out POWER_DOMAIN_MODESET handling to its own commit. Changes since v3: - Do not wait for vblank on legacy cursor updates. (Ville) - Move broadwell vblank workaround comment to page_flip_finished.

I wouldn't expect PIPESTAT based interrupts to occur anymore since vblanks/page flips/gmbus/etc should all be quiescent at this point. But at least hotplug interrupts could still occur. Hotplug interrupts may also kick off the workqueue based hotplug processing, but that code should take the required power domain references itself, so there shouldn't be any need to synchronize with the hotplug processing from the power well code.

down PIPESTAT registers live in the display power well on VLV/CHV, so we shouldn't access them when things are powered down. Let's check whether the display interrupts are on or off before accessing the PIPESTAT registers. Another option would be to read the PIPESTAT registers only when the IIR register indicates that there's a pending pipe event. But that would mean we might miss even more underrun reports than we do now, because the underrun status bit lives in PIPESTAT but doesn't actually generate an interrupt.

2016-02-19drm/i915/fbc: enable FBC by default on HSW and BDWPaulo Zanoni1-1/+3
These platforms should be fine now. FBC can allow very significant power savings for screen-on idle systems, but it is worth mentioning that a lot of people won't get significant power savings by enabling this feature because they may have something else preventing the system from getting into the deepest sleep states. Examples may include a hungry wifi device or a max_performance SATA link power management policy. You can check your PC state residencies on the powertop "Idle stats" tab. I recommend trying to run "sudo powertop --auto-tune" and then seeing if the residencies improve. Oh, and in case you - the person reading this commit message - found this commit through git bisect, please do the following: - Check your dmesg and see if there are error messages mentioning underruns around the time your problem started happening. - Download intel-gpu-tools, compile it, and run: $ sudo ./tests/kms_frontbuffer_tracking --run-subtest '*fbc-*' 2>&1 | tee fbc.txt Then send us the fbc.txt file, especially if you get a failure. This will really maximize your chances of getting the bug fixed quickly. - Try to find a reliable way to reproduce the problem, and tell us. - Boot with drm.debug=0xe, reproduce the problem, then send us the dmesg file. v2: Don't enable by default on SKL.

2016-02-18drm/i915/skl: Ensure HW is powered during DDB HW state readoutImre Deak1-1/+6
The assumption when adding the intel_display_power_is_enabled() checks was that if it returns success the power can't be turned off afterwards during the HW access, which is guaranteed by modeset locks. This isn't always true, so make sure we hold a dedicated reference for the time of the access.

2016-02-18drm/i915: Enable PSR by default on Haswell and Broadwell.Rodrigo Vivi1-1/+2
With a reliable frontbuffer tracking and all instability corner cases on Haswell and Broadwell solved let's re-enabled PSR by default on these platforms. In case a new issue is found and PSR is the main suspect, please check if i915.enable_psr=0 really makes your problem go away. If this is the case PSR is the culprit so after that please check if i915.enable_psr=2 or i915.enable_psr=3 solves your issue and please let us know. There are many panels out there and not all implementations apparently work as we would expect. In case you needed to force it on standby or disabled or in case of any PSR related bug please report it at bugs.freedesktop.org. In a bugzilla entry for PSR is desirable: - dmesg (drm.debug=0xe) - output of /sys/kernel/debug/dri/0/i915_edp_psr_status - Platform information. Vendor, model, id, pci id. - Graphical environment: Gnome, KDE, openbox, etc... - Details how to reproduce. - Also good if you could run PSR test cases of Intel-gpu-tools - Please mention if forcing main link standby or main link off helps you. There are Intel-gpu-tools test cases that can be helpful to determine if PSR is working as expected: kms_psr_sink_crc and kms_psr_frontbuffer_tracking.
