2024-01-08drm/panel-edp: use put_sync in unprepareHsin-Yi Wang1-2/+1
Some edp panel requires T10 (Delay from end of valid video data transmitted by the Source device to power-off) less than 500ms. Using autosuspend with delay set as 1000 violates this requirement. Use put_sync_suspend in unprepare to meet the spec. For other cases (such as getting EDID), it still uses autosuspend.

2024-01-08drm/xe/xe2: synchronise CS_CHICKEN1 with WMTP supportNirmoy Das2-0/+22
Recommendation is to read FUSE4 register to check if WMTP has been enabled/disabled by HW. If enabled we don't need to do anything special, however if disabled recommendation is to also disable the WMTP mode in the FF_SLICE_CS_CHICKEN2 register, falling back to thread-group and mid-batch preemption only. However on Linux, the per-context CS_CHICKEN1 is how userspace controls pre-emption, so instead use the default lrc to disable WMTP using CS_CHICKEN1, if disabled by HW. Userspace is still free to set CS_CHICKEN1 to whatever they want later. v2: remove redundant version check and also add descriptive name(Matt) v3: remove usage of REG_FIELD_GET(Matt) Cc: Matt Roper <[email protected]> Co-developed-by: Matthew Auld <[email protected]> Signed-off-by: Matthew Auld <[email protected]> Signed-off-by: Nirmoy Das <[email protected]> Reviewed-by: Matt Roper <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Matt Roper <[email protected]>

2024-01-08drm/i915/xe2lpd: Update bxt_sanitize_cdclk()Gustavo Sousa1-1/+4
With Xe2_LPD, there were changes to the way CDCLK_CTL must be programmed. Those were reflected on _bxt_set_cdclk() with commit 3d3696c0fed1 ("drm/i915/lnl: Start using CDCLK through PLL"), but bxt_sanitize_cdclk() was left out. This was causing some issues when loading the driver with a pre-existing active display configuration: the driver would mistakenly take the current value of CDCLK_CTL as wrong and the sanitization would be triggered. In a scenario where the display was already configured with a high CDCLKC and had plane(s) enabled, FIFO underrun errors were reported, because the current sanitization code selects the minimum possible CDCLK. Fix that by updating bxt_sanitize_cdclk() to match the changes made in _bxt_set_cdclk(). Ideally, we would have a common function to derive the value for CDCLK_CTL, but that can be done in a future change.

Glitches deasserting the connector HPD line can lead to incorrectly detecting a disconnect event (a glitch asserting the line will only cause a redundant connect->disconnect transition). The source of such a glitch can be noise on the line or a 0.5ms-1ms MST IRQ_HPD pulse. TypeC ports in the DP-alt or TBT-alt mode filter out these glitches inernally, but for others the driver has to do this. Make it so by polling the HPD line on these connectors for 4 ms.

2024-01-08drm/i915: Prevent modesets during driver init/shutdownImre Deak5-2/+171
An unexpected modeset or connector detection by a user (user space or FB console) during the initialization/shutdown sequence is possible either via a hotplug IRQ handling work or via the connector sysfs (status/detect) interface. These modesets/detections should be prevented by disabling/flushing all related hotplug handling work and unregistering the interfaces that can start them at the beginning of the shutdown sequence. Some of this - disabling all related intel_hotplug work - will be done by the next patch, but others - for instance disabling the MST hotplug works - require a bigger rework. It makes sense - for diagnostic purpose, even with all the above work and interface disabled - to detect and reject any such user access. This patch does that for modeset accesses and a follow-up patch for connector detection. During driver loading/unloading/system suspend/shutdown and during system resume after calling intel_display_driver_disable_user_access() or intel_display_driver_resume_access() correspondigly, the current thread is allowed to modeset (as this thread requires to do an initial/restoring modeset or a disabling modeset), other threads (the user threads) are not allowed to modeset. During driver loading/system resume after calling intel_display_driver_enable_user_access() all threads are allowed to modeset. During driver unloading/system suspend/shutdown after calling intel_display_driver_suspend_access() no threads are allowed to modeset (as the HW got disabled and should stay in this state). v2: Call intel_display_driver_suspend_access()/resume_access() only for HAS_DISPLAY().

The only purpose of intel_hpd_poll_disable() during driver loading and system resume - at which point polling should be disabled anyway, except for connectors in an IRQ storm, for which the polling will stay enabled - is to force-detect all the connectors. However this detection in i915_hpd_poll_init_work() depends on drm.mode_config.poll_enabled, which will get set in drm_kms_helper_poll_init(), possibly after i915_hpd_poll_init_work() is scheduled. Hence the initial detection of connectors during driver loading may not happen. Fix the above by moving intel_hpd_poll_disable() after i915_hpd_poll_init_work(), the proper place anyway for doing the above detection after all the HW initialization steps are complete. Change the order the same way during system resume as well. The above race condition shouldn't matter here - as drm.mode_config.poll_enabled will be set - but the detection should happen here as well after the HW init steps are done.

After an HPD IRQ storm on a connector intel_hpd_irq_storm_detect() will set the connector's HPD pin state to HPD_MARK_DISABLED and the IRQ gets disabled. Subsequently intel_hpd_irq_storm_switch_to_polling() will enable polling for these connectors, setting the pin state to HPD_DISABLED, but only if the connector's base.polled field is set to DRM_CONNECTOR_POLL_HPD. intel_hpd_irq_storm_reenable_work() will reenable the IRQ - after 2 minutes - if the pin state is HPD_DISABLED. The connectors will be created with their base.polled field set to 0, which gets initialized only later in i915_hpd_poll_init_work() (using intel_connector::polled). If a storm is detected on a connector after it's created and IRQs are enabled on it - by intel_hpd_init() - and before its bease.polled field is initialized in the above work, the connector's HPD pin will stay in the HPD_MARK_DISABLED state - leaving the IRQ disabled indefinitely - and polling will not get enabled on it as intended. I can't see a reason for initializing base.polled in a delayed manner, so do this already when creating the connector, to prevent the above race condition.

2024-01-07drm/sched: One function call less in drm_sched_init() after error detectionMarkus Elfring1-2/+3
The kfree() function was called in one case by the drm_sched_init() function during error handling even if the passed data structure member contained a null pointer. This issue was detected by using the Coccinelle software. Thus adjust a jump target.

2024-01-05drm/i915/huc: Allow for very slow HuC loadingJohn Harrison2-11/+63
A failure to load the HuC is occasionally observed where the cause is believed to be a low GT frequency leading to very long load times. So a) increase the timeout so that the user still gets a working system even in the case of slow load. And b) report the frequency during the load to see if that is the cause of the slow down. Also update the similar code on the GuC load to not use uncore->gt when there is a local gt available. The two should match, but no need for unnecessary de-referencing.

2024-01-05drm/amd/display: fix bandwidth validation failure on DCN 2.1Melissa Wen1-1/+1
IGT `amdgpu/amd_color/crtc-lut-accuracy` fails right at the beginning of the test execution, during atomic check, because DC rejects the bandwidth state for a fb sizing 64x64. The test was previously working with the deprecated dc_commit_state(). Now using dc_validate_with_context() approach, the atomic check needs to perform a full state validation. Therefore, set fast_validation to false in the dc_validate_global_state call for atomic check.

The hwmgr->backend, (i.e. data) allocated by kzalloc is not freed in the error-handling paths of smu7_get_evv_voltages and smu7_update_edc_leakage_table. However, it did be freed in the error-handling of phm_initializa_dynamic_state_adjustment_rule_settings, by smu7_hwmgr_backend_fini. So the lack of free in smu7_get_evv_voltages and smu7_update_edc_leakage_table is considered a memleak in this patch.
