drm/i915: Prevent modesets during driver init/shutdown 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(). (CI) v3: (Jouni) - Add commit log comments explaining how the permission of modeset changes during HW init/deinit wrt. to the current and other user processes.

drm/i915: Suspend the framebuffer console during driver shutdown Suspend the FB console during driver shutdown the same way this is done during system resume. This should prevent any HPD event to trigger a new FB probe/modeset cycle happening in parallel with the display HW disable/uninitialize steps. A preceding FB HPD event handling may be still pending, resulting in a probe/modeset like the above, these will be prevented by a later change in this patchset.

drm/i915: Disable intel HPD poll after DRM poll init/enable 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.

drm/i915/display: Handle GMD_ID identification in display code For platforms with GMD_ID support (i.e., everything MTL and beyond), identification of the display IP present should be based on the contents of the GMD_ID register rather than a PCI devid match. Note that since GMD_ID readout requires access to the PCI BAR, a slight change to the driver init sequence is needed --- pci_enable_device() is now called before i915_driver_create(). v2: - Fix use of uninitialized i915 pointer in error path if pci_enable_device() fails before the i915 device is created. (lkp) - Use drm_device parameter to intel_display_device_probe. This goes against i915 conventions, but since the primary goal here is to make it easy to call this function from other drivers (like Xe) and since we don't need anything from the i915 structure, this seems like an exception where drm_device is a more natural fit. v3: - Go back do drm_i915_private for intel_display_device_probe.

drm/i915/tc: Call TypeC port flush_work/cleanup without modeset locks held Call the TypeC port flush_work and cleanup handlers without the modeset locks held. These don't require the locks, as the work takes - as it should be able to at any point in time - any locks it needs and by the time cleanup is called and after cleanup returns the encoder is not in use. This is required by the next patch canceling a TypeC port work synchronously during encoder suspend and shutdown, where the work can take modeset locks as well, hence the canceling must be done without holding the locks. I also considered moving the modeset locking down to each encoder suspend()/shutdown() hook instead, however locking the full modeset state for each encoder separately would be odd, and the bigger change - affecting all encoders - is beyond the scope of this patchset. v2: - Add a TODO: comment to remove modeset locks if no encoder depends on this.

drm/i915: hide mkwrite_device_info() better The goal has been to just make device info a pointer to static const data, i.e. the static const structs in i915_pci.c. See [1]. However, there were issues with intel_device_info_runtime_init() clearing the display sub-struct of device info on the !HAS_DISPLAY() path, which consequently disables a lot of display functionality, like it should. Looks like we'd have to cover all those paths, and maybe sprinkle HAS_DISPLAY() checks in them, which we haven't gotten around to. In the mean time, hide mkwrite_device_info() better within intel_device_info.c by adding a intel_device_info_driver_create() for the very early initialization of the device info and initial runtime info. This also lets us declutter i915_drv.h a bit, and stops promoting mkwrite_device_info() as something that could be used.

drm/i915/pxp: Pxp hw init should be in resume_complete During suspend flow, i915 currently achors' on the pm_suspend_prepare callback as the location where we quiesce the entire GPU and perform all necessary cleanup in order to go into suspend. PXP is also called during this time to perform the arbitration session teardown (with the assurance no additional GEM IOCTLs will come after that could restart the session). However, if other devices or drivers fail their suspend_prepare, the system will not go into suspend and i915 will be expected to resume operation. In this case, we need to re-initialize the PXP hardware and this really should be done within the pm_resume_complete callback which is the correct opposing function in the resume sequence to match pm_suspend_prepare of the suspend sequence. Because this callback is the last thing at the end of resuming we expect little to no impact to the rest of the i915 resume sequence with this change.

drm/i915/pxp: Promote pxp subsystem to top-level of i915 Starting with MTL, there will be two GT-tiles, a render and media tile. PXP as a service for supporting workloads with protected contexts and protected buffers can be subscribed by process workloads on any tile. However, depending on the platform, only one of the tiles is used for control events pertaining to PXP operation (such as creating the arbitration session and session tear-down). PXP as a global feature is accessible via batch buffer instructions on any engine/tile and the coherency across tiles is handled implicitly by the HW. In fact, for the foreseeable future, we are expecting this single-control-tile for the PXP subsystem. In MTL, it's the standalone media tile (not the root tile) because it contains the VDBOX and KCR engine (among the assets PXP relies on for those events). Looking at the current code design, each tile is represented by the intel_gt structure while the intel_pxp structure currently hangs off the intel_gt structure. Keeping the intel_pxp structure within the intel_gt structure makes some internal functionalities more straight forward but adds code complexity to code readability and maintainibility to many external-to-pxp subsystems which may need to pick the correct intel_gt structure. An example of this would be the intel_pxp_is_active or intel_pxp_is_enabled functionality which should be viewed as a global level inquiry, not a per-gt inquiry. That said, this series promotes the intel_pxp structure into the drm_i915_private structure making it a top-level subsystem and the PXP subsystem will select the control gt internally and keep a pointer to it for internal reference. This promotion comes with two noteworthy changes: 1. Exported pxp functions that are called by external subsystems (such as intel_pxp_enabled/active) will have to check implicitly if i915->pxp is valid as that structure will not be allocated for HW that doesn't support PXP. 2. Since GT is now considered a soft-dependency of PXP we are ensuring that GT init happens before PXP init and vice versa for fini. This causes a minor ordering change whereby we previously called intel_pxp_suspend after intel_uc_suspend but now is before i915_gem_suspend_late but the change is required for correct dependency flows. Additionally, this re-order change doesn't have any impact because at that point in either case, the top level entry to i915 won't observe any PXP events (since the GPU was quiesced during suspend_prepare). Also, any PXP event doesn't really matter when we disable the PXP HW (global GT irqs are already off anyway, so even if there was a bug that generated spurious events we wouldn't see it and we would just clean it up on resume which is okay since the default fallback action for PXP would be to keep the sessions off at this suspend stage). Changes from prior revs: v11: - Reformat a comment (Tvrtko). v10: - Change the code flow for intel_pxp_init to make it more cleaner and readible with better comments explaining the difference between full-PXP-feature vs the partial-teelink inits depending on the platform. Additionally, only do the pxp allocation when we are certain the subsystem is needed. (Tvrtko). v9: - Cosmetic cleanups in supported/enabled/active. (Daniele). - Add comments for intel_pxp_init and pxp_get_ctrl_gt that explain the functional flow for when PXP is not supported but the backend-assets are needed for HuC authentication (Daniele and Tvrtko). - Fix two remaining functions that are accessible outside PXP that need to be checking pxp ptrs before using them: intel_pxp_irq_handler and intel_pxp_huc_load_and_auth (Tvrtko and Daniele). - User helper macro in pxp-debugfs (Tvrtko). v8: - Remove pxp_to_gt macro (Daniele). - Fix a bug in pxp_get_ctrl_gt for the case of MTL and we don't support GSC-FW on it. (Daniele). - Leave i915->pxp as NULL if we dont support PXP and in line with that, do additional validity check on i915->pxp for intel_pxp_is_supported/enabled/active (Daniele). - Remove unncessary include header from intel_gt_debugfs.c and check drm_minor i915->drm.primary (Daniele). - Other cosmetics / minor issues / more comments on suspend flow order change (Daniele). v7: - Drop i915_dev_to_pxp and in intel_pxp_init use 'i915->pxp' through out instead of local variable newpxp. (Rodrigo) - In the case intel_pxp_fini is called during driver unload but after i915 loading failed without pxp being allocated, check i915->pxp before referencing it. (Alan) v6: - Remove HAS_PXP macro and replace it with intel_pxp_is_supported because : [1] introduction of 'ctrl_gt' means we correct this for MTL's upcoming series now. [2] Also, this has little impact globally as its only used by PXP-internal callers at the moment. - Change intel_pxp_init/fini to take in i915 as its input to avoid ptr-to-ptr in init/fini calls.(Jani). - Remove the backpointer from pxp->i915 since we can use pxp->ctrl_gt->i915 if we need it. (Rodrigo). v5: - Switch from series to single patch (Rodrigo). - change function name from pxp_get_kcr_owner_gt to pxp_get_ctrl_gt. - Fix CI BAT failure by removing redundant call to intel_pxp_fini from driver-remove. - NOTE: remaining open still persists on using ptr-to-ptr and back-ptr. v4: - Instead of maintaining intel_pxp as an intel_gt structure member and creating a number of convoluted helpers that takes in i915 as input and redirects to the correct intel_gt or takes any intel_gt and internally replaces with the correct intel_gt, promote it to be a top-level i915 structure. v3: - Rename gt level helper functions to "intel_pxp_is_enabled/ supported/ active_on_gt" (Daniele) - Upgrade _gt_supports_pxp to replace what was intel_gtpxp_is supported as the new intel_pxp_is_supported_on_gt to check for PXP feature support vs the tee support for huc authentication. Fix pxp-debugfs-registration to use only the former to decide support. (Daniele) - Couple minor optimizations. v2: - Avoid introduction of new device info or gt variables and use existing checks / macros to differentiate the correct GT->PXP control ownership (Daniele Ceraolo Spurio) - Don't reuse the updated global-checkers for per-GT callers (such as other files within PXP) to avoid unnecessary GT-reparsing, expose a replacement helper like the prior ones. (Daniele). v1: - Add one more patch to the series for the intel_pxp suspend/resume for similar refactoring References: https://patchwork.freedesktop.org/patch/msgid/20221202011407.4068371-1-alan.previn.teres.alexis@intel.com Signed-off-by: Alan Previn <alan.previn.teres.alexis@intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221208180542.998148-1-alan.previn.teres.alexis@intel.com

drm/i915: Allow switching away via vga-switcheroo if uninitialized Always allow switching away via vga-switcheroo if the display is uninitalized. Instead prevent switching to i915 if the device has not been initialized. This issue was introduced by commit 5df7bd130818 ("drm/i915: skip display initialization when there is no display") protected, which protects code paths from being executed on uninitialized devices. In the case of vga-switcheroo, we want to allow a switch away from i915's device. So run vga_switcheroo_process_delayed_switch() and test in the switcheroo callbacks if the i915 device is available.

drm/i915: Only hook up uncore->debug for primary uncore The original intent of intel_uncore_mmio_debug as described in commit 0a9b26306d6a ("drm/i915: split out uncore_mmio_debug") was to be a singleton structure that could be shared between multiple GTs' uncore objects in a multi-tile system. Somehow we went off track and started allocating separate instances of this structure for each GT, which defeats that original goal. But in reality, there isn't even a need to share the mmio_debug between multiple GTs; on all modern platforms (i.e., everything after gen7) unclaimed register accesses are something that can only be detected for display registers. There's no point in grabbing the debug spinlock and checking for unclaimed accesses on an uncore used by an xehpsdv or pvc remote tile GT, or the uncore used by a mtl standalone media GT since all of the display accesses go through the primary intel_uncore. The simplest solution is to simply leave uncore->debug NULL on all intel_uncore instances except for the primary one. This will allow us to avoid the pointless debug spinlock acquisition we've been doing on MMIO accesses coming in through these intel_uncores.

drm/i915: Improve on suspend / resume time with VT-d enabled When DMAR / VT-d is enabled, the display engine uses overfetching, presumably to deal with the increased latency. To avoid display engine errors and DMAR faults, as a workaround the GGTT is populated with scatch PTEs when VT-d is enabled. However starting with gen10, Write-combined writing of scratch PTES is no longer possible and as a result, populating the full GGTT with scratch PTEs like on resume becomes very slow as uncached access is needed. Therefore, on integrated GPUs utilize the fact that the PTEs are stored in stolen memory which retain content across S3 suspend. Don't clear the PTEs on suspend and resume. This improves on resume time with around 100 ms. While 100+ms might appear like a short time it's 10% to 20% of total resume time and important in some applications. One notable exception is Intel Rapid Start Technology which may cause stolen memory to be lost across what the OS percieves as S3 suspend. If IRST is enabled or if we can't detect whether IRST is enabled, retain the old workaround, clearing and re-instating PTEs. As an additional measure, if we detect that the last ggtt pte was lost during suspend, print a warning and re-populate the GGTT ptes On discrete GPUs, the display engine scans out from LMEM which isn't subject to DMAR, and presumably the workaround is therefore not needed, but that needs to be verified and disabling the workaround for dGPU, if possible, will be deferred to a follow-up patch. v2: - Rely on retained ptes to also speed up suspend and resume re-binding. - Re-build GGTT ptes if Intel rst is enabled. v3: - Re-build GGTT ptes also if we can't detect whether Intel rst is enabled, and if the guard page PTE and end of GGTT was lost. v4: - Fix some kerneldoc issues (Matthew Auld), rebase.

drm/i915: split out i915_reg_read_ioctl() to i915_ioctl.[ch] Add new files i915_ioctl.[ch] to hold small ioctls that are out of place everywhere else, and not big enough to warrant a file of their own. For starters, it's just for i915_reg_read_ioctl() that's a bit high level for a low level implementation that intel_uncore.[ch] is.

drm/i915/trace: split out display trace to a separate file Add display/intel_display_trace.[ch] for defining display tracepoints. The main goal is to reduce cross-includes between gem and display. It would be possible split up tracing even further, but that would lead to more boilerplate. We end up having to include intel_crtc.h in a few places because it was pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and that's no longer the case. There should be no changes to tracepoints. v3: - Rebase v2: - Define TRACE_INCLUDE_PATH relative to define_trace.h (Chris) - Remove useless comments (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/7862ad764fbd0748d903c76bc632d3d277874e5b.1638961423.git.jani.nikula@intel.com
