Do some further clean up based on the initial review of drm/i915: Separate cherryview from valleyview. In this case check for '(GEN7 || GEN8) && HAS_PCH_SPLIT' since we're reading FUSE_STRAP and SFUSE_STRAP which live in the PCH.

The cherryview device shares many characteristics with the valleyview device. When support was added to the driver for cherryview, the corresponding device info structure included .is_valleyview = 1. This is not correct and leads to some confusion. This patch changes .is_valleyview to .is_cherryview in the cherryview device info structure and simplifies the IS_CHERRYVIEW macro. Then where appropriate, instances of IS_VALLEYVIEW are replaced with IS_VALLEYVIEW || IS_CHERRYVIEW or equivalent. v2: Use IS_VALLEYVIEW || IS_CHERRYVIEW instead of defining a new macro. Also add followup patches to fix issues discovered during the first review. (Ville) v3: Fix some style issues and one gen check. Remove CRT related changes as CRT is not supported on CHV. (Imre, Ville) v4: Make a few more optimizations. (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:Jani Nikula <jani.nikula@intel.com>

In order to avoid accessing GPU registers while GPU is suspended cancel the hangcheck work before calling intel_suspend_complete which actually puts the GPU to suspend. Otherwise hangcheck might do MMIO reads to a suspended GPU. Placement before intel_guc_suspend is imitated from i915_drm_suspend which cancels the work at i915_gem_suspend, to keep the functions similar. On VLV systems, namely BYT, this was causing an error during runtime suspend cycle: [drm:vlv_check_no_gt_access [i915]] *ERROR* GT register access while GT waking disabled Testcase: igt/pm_rpm/basic-rte Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93121Signed-off-by:

All of these iterator macros require a 'temp' argument, used merely to hold internal partial results. We can instead declare the temporary variable inside the macro, so the caller need not provide it. Some of the old code contained nested iterators that actually reused the same 'temp' variable for both inner and outer instances. It's quite surprising that this didn't introduce bugs! But it does show that the value of 'temp' isn't required to persist during the iterated body. Signed-off-by:

Userspace can pass in an offset that it presumes the object is located at. The kernel will then do its utmost to fit the object into that location. The assumption is that userspace is handling its own object locations (for example along with full-ppgtt) and that the kernel will rarely have to make space for the user's requests. Signed-off-by:

As described in the code comment, I couldn't set the minimum RPS frequency on my BYT-M B0 to the minimum allowed as reported by Punit. Fix this by clamping the minimum value to the first one that was accepted on my machine. Atm this issue doesn't cause any test failures, since in igt/pm_rps we only check the cached version of the current frequency which is the same what has been set. In the future we'll add checks for the actual frequency too, and for that to pass this fix is necessary. Signed-off-by:

Currently we disable some parts of FDI setup after a failed link training. But despite that we continue with the modeset as if everything is fine. This results in tons of noise from the state checker, and it means we're not following the proper modeset sequence for the rest of crtc enabling, nor for crtc disabling. Ideally we should abort the modeset and follow the proper disable sequence to shut off everything we enabled so far, but that would require a big rework of the modeset code. So instead just leave FDI up and running in its untrained state, and log an error. This is what we do on older platforms too. v2: Fix a typo in the commit message Signed-off-by:

Bspec modeset sequence tells us to disable the PCH transcoder and FDI after the CRT port on LPT-H, so let's do that. And the CRT port should be disabled after the pipe, as we do on other PCH platforms too since commit 1ea56e26 ("drm/i915: Disable CRT port after pipe on PCH platforms") commit 00490c22 ("drm/i915: Consider SPLL as another shared pll, v2.") moved the SPLL disable from the .post_disable() hook to some upper level code, so we can just move the CRT port disabling into the .post_disable() hook. If we still had the non-shared SPLL, it would have needed to be moved into the .post_pll_disable() hook. v2: Actually move the CRT port disable to the .post_disable() hook, and amend the commit message with more details (Paulo) v3: Fix typos in commit message (Paulo) Cc: Paulo Zanoni <przanoni@gmail.com> Signed-off-by:

When we want to use SPLL for FDI we want SSC, which means we have to disable clock bending for the PCH SSC reference (bend and spread are mutually exclusive). So let's turn off bending when we want spread. In case the BIOS enabled clock bending for some reason we'll just turn it off and enable the spread mode instead. Not sure what happens if the BIOS is actually using the bend source for HDMI at this time, but I suppose it should be no worse than what already happens when we simply turn on the spread. We don't currently use the bend source for anything, and only use the PCH SSC reference for the SPLL to drive FDI (always with spread). v2: Fix the %5 vs %10 fumble for SSCDITHPHASE (Paulo) Add 'WARN_ON(steps % 5 != 0)' sanity check (Paulo) Fix typos in commit message (Paulo) Cc: Paulo Zanoni <przanoni@gmail.com> Signed-off-by: -

'commit 97173eaf ("drm/i915: PSR: Increase idle_frames")' was a mistake. The special case it tried to cover was already being covered by the DP_PSR_NO_TRAIN_ON_EXIT. So this ended up duplicated. So, instead of reverting that let's take this opportunity and unify the idle_frame definition in a single place so we standardize the access and avoid room for that same mistake again. Few changes with this patch: 1. Instead of just respecting the VBT we set a global minumum with max(). So we are sure that we will avoid corner cases in case VBT is doing something we don't understand. 2. Instead of minimum 5 we use 6. When introducing the idle_frames += 4 case we considered that minimum was 2. All because the off-by-one issue. v2: Unified idle_frame definition.

This reverts commit 6d65ba94. Mika Kuoppala traced down a use-after-free crash in module unload to this commit, because ring->last_context is leaked beyond when the context gets destroyed. Mika submitted a quick fix to patch that up in the context destruction code, but that's too much of a hack. The right fix is instead for the ring to hold a full reference onto it's last context, like we do for legacy contexts. Since this is causing a regression in BAT it gets reverted before we can close this.

In commit 2e1b8730 [v4.2] Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Apr 27 13:41:22 2015 +0100 drm/i915: Convert RPS tracking to a intel_rps_client struct we converted the __i915_wait_request() to take a new intel_rps_client struct (rather than having to pass fake drm_i915_file_private structs). However, due to use of passing a void pointer, I didn't spot one callsite in wait-ioctl was passing the wrong pointer. Fwiw, the impact of this bug is zero. Along the rps path, we always first call list_empty(rps) which when we pass in the wrong pointer always evaluates to false and we return early and never chase the invalid pointers. The user visible impact is then wait-ioctl doesn't get the same waitboosting as the other interfaces (set-domain, throttle), which is a performance concern for the *very* few users of the wait interface. There is also a libdrm_intel patch to use the wait-ioctl for drm_intel_bo_wait_rendering() if anyone feels inclined to review libdrm_intel patches. Signed-off-by:

Beginning with gen7, newer devices repetitively redefine values for the device info structure members. This patch simplifies the structure definitions by grouping member value definitions into the existing GEN7_FEATURES #define and into the new GEN7_LP_FEATURES and HSW_FEATURES #defines. Specifically, GEN_DEFAULT_PIPEOFFSETS and IVB_CURSOR_OFFSETS are added to GEN7_FEATURES and subsequent IVB definitions are simplified. VLV_FEATURES is defined to differentiate and simplify the gen7 low power (LP) devices. HSW_FEATURES is defined and used to simplify all HSW+ devices except for LP. v2: Use VLV_FEATURES for the gen7 low power devices. (Jani) Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:

Use the first retired request on a new context to unpin the old context. This ensures that the hw context remains bound until it has been written back to by the GPU. Now that the context is pinned until later in the request/context lifecycle, it no longer needs to be pinned from context_queue to retire_requests. This fixes an issue with GuC submission where the GPU might not have finished writing back the context before it is unpinned.
