Interrupts other than the one for AUX errors are required only for debug, so unmask them via debugfs when the user requests debug. User can make such a request with echo 1 > <DEBUG_FS>/dri/0/i915_edp_psr_debug There are no locks to serialize PSR debug enabling from irq_postinstall() and debugfs for simplicity. As irq_postinstall() is called only during module initialization/resume and IGT subtests aren't expected to modify PSR debug at those times, we should be safe. v2: Unroll loops (Ville) Avoid resetting error mask bits. v3: Unmask interrupts in postinstall() if debug was still enabled. Avoid RMW (Ville) v4: Avoid extra IMR write introduced in the previous version.(Jose) Style changes, renames (Jose).

The definitions for the error register should be valid on bdw/skl too, but there we haven't even enabled DE_MISC handling yet. Somewhat confusing the the moved register offset on bdw is only for the _CTL/_AUX register, and that _IIR/IMR stayed where they have been on bdw. v2: Fixes from Ville. v3: From DK * Rebased on drm-tip * Removed BDW IIR bit definition, looks like an unintentional change that should be in the following patch. v4: From DK * Don't mask REG_WRITE.

In GLK when the device boots with only 1366x768 panel without audio, HDA codec doesn't come up. In this case, the CDCLK is less than twice the BCLK. Even though audio isn't being enabled, having a too low CDCLK leads to audio probe failing altogether. Require CDCLK to be at least twice the BLCK regardless of audio. This is a minimal fix to improve things. Unfortunately, this a) leads to too high CDCLK being used when audio is not used, and b) is still not enough to fix audio probe when no outputs are connected at probe time. The proper fix would be to increase CDCLK dynamically from the audio component hooks. v2: - Address comment (Jani) - New design approach v3: - Typo fix on top of v1 v4 by Jani: rewrite commit message, add comment in code Cc: stable@vger.kernel.org Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@gmail.com> Cc: Wenkai Du <wenkai.du@intel.com> Reviewed-by:Wenkai Du <wenkai.du@intel.com> Tested-by:

Today we only want to pass along the priority to engine->schedule(), but in the future we want to have much more control over the various aspects of the GPU during a context's execution, for example controlling the frequency allowed. As we need an ever growing number of parameters for scheduling, move those into a struct for convenience. v2: Move the anonymous struct into its own function for legibility and ye olde gcc.

On Geminilake, sometimes audio card is not getting detected after reboot. This is a spurious issue happening on Geminilake.

We have to cleanup after i915_perf_init(), even on the error path, as it passes a pointer into the module to the sysfs core. If we fail to unregister the sysctl table, we leave a dangling pointer which then may explode anytime later.

Add a selftest to ensure that we restore the whitelisted registers after rewrite the registers everytime they might be scrubbed, e.g. module load, reset and resume. For the other volatile workaround registers, we export their presence via debugfs and check in igt/gem_workarounds. However, we don't export the whitelist and rather than do so, let's test them directly in the kernel. The test we use is to read the registers back from the CS (this helps us be sure that the registers will be valid for MI_LRI etc). In order to generate the expected list, we split intel_whitelist_workarounds_emit into two phases, the first to build the list and the second to apply. Inside the test, we only build the list and then check that list against the hw. v2: Filter out pre-gen8 as they do not have RING_NONPRIV. v3: Drop unused engine parameter, no plans to use it now or future.

The VBT contains the DDC pin to use for specific ports. Alas, sometimes the field appears to contain bogus data, and while we check for it later on in intel_gmbus_get_adapter() we fail to check the returned NULL on errors. Oops results. The simplest approach seems to be to catch and ignore the bogus DDC pins already at the VBT parsing phase, reverting to fixed per port default pins. This doesn't guarantee display working, but at least it prevents the oops. And we continue to be fuzzed by VBT. One affected machine is Dell Latitude 5590 where a BIOS upgrade added invalid DDC pins.

There are different kind of workarounds (those that modify registers that live in the context image, those that modify global registers, those that whitelist registers, etc...) and they have different requirements in terms of where they are applied and how. Also, by splitting them apart, it should be easier to decide where a new workaround should go. v2: - Add multiple MISSING_CASE - Rebased v3: - Rename mmio_workarounds to gt_workarounds (Chris, Mika) - Create empty placeholders for BDW and CHV GT WAs - Rebased v4: Rebased v5: - Rebased - FORCE_TO_NONPRIV register exists since BDW, so make a path for it to achieve universality, even if empty (Chris) Signed-off-by:

For the moment, we are leaving behind the WA BB code and the WAs that get applied (incorrectly) in init_clock_gating, but we will deal with it later. v2: Use intel_ prefix for code that deals with the hardware (Chris) v3: Rebased v4: - Rebased - New license header v5: - Rebased - Added some organisational notes to the file (Chris) v6: Include DOC section in the documentation build (Jani) Signed-off-by:

We can refine our current execlists->queue_priority if we inspect ELSP[1] rather than the head of the unsubmitted queue. Currently, we use the unsubmitted queue and say that if a subsequent request is more important than the current queue, we will rerun the submission tasklet to evaluate the need for preemption. However, we only want to preempt if we need to jump ahead of a currently executing request in ELSP. The second reason for running the submission tasklet is amalgamate requests into the active context on ELSP[0] to avoid a stall when ELSP[0] drains. (Though repeatedly amalgamating requests into the active context and triggering many lite-restore is off question gain, the goal really is to put a context into ELSP[1] to cover the interrupt.) So if instead of looking at the head of the queue, we look at the context in ELSP[1] we can answer both of the questions more accurately -- we don't need to rerun the submission tasklet unless our new request is important enough to feed into, at least, ELSP[1]. v2: Add some comments from the discussion with Tvrtko. v3: More commentary to cross-reference queue_request() References: f6322edd ("drm/i915/preemption: Allow preemption between submission ports") Signed-off-by:

While thinking about sporadic failures of perf_pmu/rc6-runtime-pm* tests on some CI machines I have concluded that: a) the PMU readout of RC6 can race against runtime PM transitions, and b) there are other reasons than being runtime suspended which can cause intel_runtime_pm_get_if_in_use to fail. Therefore when estimating RC6 the code needs to assert we are indeed in suspended state, and if not, the best we can do is return the last known RC6 value. Without this check we can calculate the estimated value based on un- initialized or inappropriate internal state, which can result in over- estimation, or in any case incorrect value being returned. v2: * Re-arrange the code a bit to avoid second unlock and return branch. (Chris Wilson) v3: * Insert some strategic blank lines and improve commit msg. (Chris Wilson) Signed-off-by:

Resetting the GPU doesn't affect the RPS/RC6 state, so we can stop forcibly reloading the registers. Ville suggested this many moons ago, I said at that time that sanitizing was no harm and meant that our bookkeeping was kept consistent with the HW. However, in a forthcoming series, we want to split rps/rc6 GT powermanagement and one of the key simplifications is the control of when we enable it. Performing a crude sanitize in the middle of i915_gem_reset() is then a huge wart. Suggested-by:

Adding a i915_fifo_underrun_reset debugfs file will make it possible for IGT tests to clear FIFO underrun fallout at the start of each subtest, and make re-enable FBC so tests always have maximum exposure to features used by IGT. FIFO underruns and FBC bugs will no longer hide when an earlier subtests disables both. Signed-off-by:

Inside the psr work function, we want to wait for PSR to idle first and wish to do so without blocking the normal modeset path, so we do so without holding the PSR lock. However, we first have to find which pipe PSR was enabled on, which requires chasing into the PSR struct and requires locking to prevent intel_psr_disable() from concurrently setting our pointer to NULL.

On GLK sporadic timeouts occur during PHY0 enabling. Based on logs it looks like they happen sometime after a system suspend/resume cycle, with the same power well enabling succeeding both before and after the failed one and no other problems observed. The current timeout in the code is not actually specified by BSpec, so let's try to increase that until a BSpec update. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105771Signed-off-by:

This patch updates scaler max limit support for NV12 v2: Rebased (me) v3: Rebased (me) v4: Missed the Tested-by/Reviewed-by in the previous series Adding the same to commit message in this version. v5: Addressed review comments from Ville and rebased - calculation of max_scale to be made less convoluted by splitting it up a bit - Indentation errors to be fixed in the series v6: Rebased (me) Fixed review comments from Paauwe, Bob J Previous version, where a split of calculation was done, was wrong. Fixed that issue here. v7: Rebased (me) v8: Rebased (me) v9: Rebased (me) v10: Rebased (me) v11: Addressed review comments from Shashank Sharma Alignment issues fixed. When call to skl_update_scaler is made, 0 was being sent instead of pixel_format. When crtc update scaler is called, we dont have the fb to derive the pixel format. Added the function parameter bool plane_scaler_check to account for this. v12: Fixed failure in IGT debugfs_test. fb is NULL in skl_update_scaler_plane Due to this, accessing fb->format caused failure. Patch checks fb before using. v13: In the previous version there was a flaw. In skl_update_scaler during plane_scaler_check if the format was non-NV12, it would set need_scaling to false. This could reset the previously set need_scaling from a previous condition check. Patch fixes this. Patch also adds minimum src height for YUV 420 formats to 16 (as defined in BSpec) and adds for checking this range. v14: Addressed review comments from Maarten Just add a check for NV12 min src height in skl_update_scaler and retain the remaining checks as is. Added Reviewed By from Juha-Pekka Heikkila. v15: Rebased the series. v16: Changed fb height restriction to be >= 16 as per Bspec. Earlier it was > 16. v17: Adding src width and height to be mult of 4 restriction to avoid pipe fifo underruns for NV12. Credits-to: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Tested-by:
