Because having both i915_gem_object_alloc() and i915_gem_alloc_object() (with different return conventions) is just too confusing! (i915_gem_object_alloc() is the low-level memory allocator, and remains unchanged, whereas i915_gem_alloc_object() is a constructor that ALSO initialises the newly-allocated object.) Signed-off-by:

As a part of WaGsvDisableTurbo, Driver makes an early exit from the Gen9 Turbo enabling function, so doesn't program the Turbo Control register. But BIOS could leave the Hw Turbo as enabled, so need to explicitly clear out the Control register just to avoid inconsitency with debugfs interface, which will show Turbo as enabled only and that is not expected after adding the WaGsvDisableTurbo. Apart from this there is no problem even if the Turbo is left enabled in the Control register, as the Up/Down interrupts would remain masked. v2: Add explicit clearing of Turbo Control register to *_disable_rps() also for the similar consistency (Chris) Reviewed-by:

There are certain registers, which captures the time elapsed in the in current Up/Down EI, for how long GT has been Idle/Busy/Avg in the current Up/Down EI and also in the previous Up/Down EI. These register values are reported by the i915_frequency_info debugfs interface. The Driver prints the 'us' suffix after the values, albeit they are actually in raw form & not in microsecond units. This patch removes the 'us' suffix so that its clear to User that values are indeed in raw form. v2: Present the values in microseconds unit also, after platform specific conversion (Chris) v3: Add a space between raw & microsecond value (Chris) Reviewed-by:

Somehow my SNB GT1 (Dell XPS 8300) gets very unhappy around GPU hangs if the RPS EI/thresholds aren't suitably aligned. It seems like scheduling/timer interupts stop working somehow and things get stuck eg. in usleep_range(). I bisected the problem down to commit 8a586437 ("drm/i915/skl: Restructured the gen6_set_rps_thresholds function") I observed that before all the values were at least multiples of 25, but afterwards they are not. And rounding things up to the next multiple of 25 does seem to help, so lets' do that. I also tried roundup(..., 5) but that wasn't sufficient. Also I have no idea if we might need this sort of thing on gen9+ as well. These are the original EI/thresholds: LOW_POWER GEN6_RP_UP_EI 12500 GEN6_RP_UP_THRESHOLD 11800 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 21250 BETWEEN GEN6_RP_UP_EI 10250 GEN6_RP_UP_THRESHOLD 9225 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 18750 HIGH_POWER GEN6_RP_UP_EI 8000 GEN6_RP_UP_THRESHOLD 6800 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 15000 These are after 8a586437: LOW_POWER GEN6_RP_UP_EI 12500 GEN6_RP_UP_THRESHOLD 11875 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 21250 BETWEEN GEN6_RP_UP_EI 10156 GEN6_RP_UP_THRESHOLD 9140 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 18750 HIGH_POWER GEN6_RP_UP_EI 7812 GEN6_RP_UP_THRESHOLD 6640 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 15000 And these are what we have after this patch: LOW_POWER GEN6_RP_UP_EI 12500 GEN6_RP_UP_THRESHOLD 11875 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 21250 BETWEEN GEN6_RP_UP_EI 10175 GEN6_RP_UP_THRESHOLD 9150 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 18750 HIGH_POWER GEN6_RP_UP_EI 7825 GEN6_RP_UP_THRESHOLD 6650 GEN6_RP_DOWN_EI 25000 GEN6_RP_DOWN_THRESHOLD 15000 Cc: stable@vger.kernel.org Cc: Akash Goel <akash.goel@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Testcase: igt/kms_pipe_crc_basic/hang-read-crc-pipe-B Fixes: 8a586437 ("drm/i915/skl: Restructured the gen6_set_rps_thresholds function") Signed-off-by:

It's possible that BIOS enables PHY0, but it programmes only the first channel on it. Since we program the PHYs only during driver loading this is an incorrect configuration from the driver's point of view, since we may use both channels eventually. Detect this scenario and force reprogramming the PHY in this case. The actual scenario for me was that the lane optimization for the second channel in PHY0 was not setup by BIOS and so a state verification warning was triggered. Everything else was setup properly.

Imre Deak authored
Initially we thought that the platform specific suspend/resume sequences can be shared between the runtime and system suspend/resume handlers. This turned out to be not true, we have quite a few differences on most of the platforms. This was realized already earlier by Paulo who inlined the platform specific resume_prepare handlers. We have the same problem with the corresponding suspend_complete handlers, there are platform differences that make it unfeasible to share the code between the runtime and system suspend paths. Also now we call functions that need to be paired like hsw_enable_pc8()/hsw_disable_pc8() from different levels of the call stack, which is confusing. Fix this by inlining the suspend_complete handlers too. This is also needed by the next patch that removes a redundant uninit/init call during system suspend/resume on BXT. No functional change.

The newly-introduced function i915_gem_object_pin_map() returns an ERR_PTR (not NULL) if the pin-and-map opertaion fails, so that's what we must check for. And it's nicer not to assign such a pointer-or-error to a structure being filled in until after it's been validated, so we should keep it local and avoid exporting a bogus pointer. Also, for clarity and symmetry, we should clear 'virtual_start' along with 'vma' when unmapping a ringbuffer. Signed-off-by:

Since we can only swap out shmemfs objects, those are the only ones that can influence the ability of the shrinker to free pages. Currently, all non-shmemfs objects have a raised pages_pin_count to protect them from the shrinker, so this just makes the logic for can_release_pages() clearer (and safer in future so that we don't over estimate our ability to free up pages from future non-swappable objects).

Inside the shrinker we call can_release_pages() to indicate whether or not we can make forward progress in freeing up memory by unbinding that object. When adding our report to oom, we should be using the same logic. Whilst here, change the reporting from bytes to pages so that it looks smaller to the user!, is consistent with the neighbouring oom report itself which displays counts in pages, and makes the unsigned long overflow less likely. v2: Split oversized format string into two lines Signed-off-by:

When iterating over the bound list, we expect all objects there to have their pages pinned (by the bound VMA). So only report those objects with additional pin count on their pages as "pinned". These should be those objects used for display and hardware access. Reported-by:

Looks like DPF was not implemented for gen8+ but the IER and IMR are still enabled on initialization. Since there is no code to handle this interrupt, gate the irq enablement behind HAS_L3_DPF in case the feature gets enabled in the future. Signed-off-by:

Since commit 30d9aa42 ("drm/i915: Read sink_count dpcd always"), the status of a DP connector depends on its sink count value. However, some eDP panels don't set that value appropriately, causing them to be reported as disconnected. Fix this by ignoring sink count for eDP. v2: Rephrased commit message. (Ander) In case of eDP, returning status as connected if DPCD read succeeds to avoid any further operations.

In commit 7d23e3c3 ("drm/i915: Cleaning up intel_dp_hpd_pulse") some much needed clean-up was done, but unfortunately part of the change broke DP MST. The real issue was setting the connector state to disconnected in the MST case, which is good, but the code then (after a goto) checks if the connector state is not connected and shuts down MST if this is the case, which is bad. With this change both SST and MST seem to be happy. v2: Add removed check further up in the function to be sure that MST is shut down when we lose the link.
