The VT-d spec requires (10.4.4 Global Command Register, TE field) that: Hardware implementations supporting DMA draining must drain any in-flight DMA read/write requests queued within the Root-Complex before completing the translation enable command and reflecting the status of the command through the TES field in the Global Status register. Unfortunately, some integrated graphic devices fail to do so after some kind of power state transition. As the result, the system might stuck in iommu_disable_translati on(), waiting for the completion of TE transition. This adds RPLS to a quirk list for those devices and skips TE disabling if the qurik hits. Link: https://gitlab.freedesktop.org/drm/intel/-/issues/4898Tested-by:

Move intel_display_power_well_is_enabled() to intel_power_well.c, as a step towards making the low-level power well internals (i915_power_well_ops/desc structs) hidden. Eventually the call to this function and in general accessing power wells directly from elsewhere in the driver should be replaced by the use of power domains. No functional change. Suggested-by:

Add a function to call a power well's sync_hw() hook, instead of open-coding the same, as a step towards making the low-level power well internals (i915_power_well_ops/desc structs) hidden.

Move the power well get/put/enable/disable hooks to the new intel_display_power_well.c file. The motivation is to reduce the clutter in intel_display_power.c, keeping the functionality related to power domains in that file and moving the low-level power well functionality to intel_display_power_well.c. No functional change. Suggested-by:

Commit d5ce34da ("drm/i915: Add state verification for the TypeC port mode") added a verification to the TypeC AUX power well enable()/disable() hooks to check if the TypeC port related to this power well is properly locked. If the disabling happens asynchronously the verification is skipped, since in this case the port is unlocked. The detection of asnychronous disabling doesn't work as intended though, since the power well's reference count is always 0 when its disable() hook is called (and since there won't be any domain reference held for this power well either, the verification is always skipped); remove the verification from the disable() hook for now. In the power well's enable() hook the power well's reference will be always >0 and there won't be any asynchronous disabling pending for it, so we can drop the async refcount check from there. No functional change. Signed-off-by:

Instead of open-coding the call of the power wells' enable()/disable() hooks use the corresponding helper functions. This will also ensure that the power well's cached-enable state is always up-to-date. Luckily the lack of this updating hasn't been a problem, since the state either didn't change (in intel_display_power_set_target_dc_state()), or got updated subsequently (for vlv_cmnlane_wa(), in the following intel_power_domains_sync_hw()).

The POWER_DOMAIN_TRANSCODER() macro depends on the POWER_DOMAIN_TRANSCODER_A/B .. DSI_A/C enum values to be consecutive, move POWER_DOMAIN_TRANSCODER_VDSC_PW2 after these to ensure this. The wrong order didn't cause a problem, since the DSI_A/C domains are in always-on power wells on all relevant platforms. The same power well ends up being enabled/disabled when the VDSC_PW2 domain is selected incorrectly. While at it add a code comment about enum values that need to stay consecutive. Signed-off-by:

oom reaping (__oom_reap_task_mm) relies on a 2 way synchronization with exit_mmap. First it relies on the mmap_lock to exclude from unlock path[1], page tables tear down (free_pgtables) and vma destruction. This alone is not sufficient because mm->mmap is never reset. For historical reasons[2] the lock is taken there is also MMF_OOM_SKIP set for oom victims before. The oom reaper only ever looks at oom victims so the whole scheme works properly but process_mrelease can opearate on any task (with fatal signals pending) which doesn't really imply oom victims. That means that the MMF_OOM_SKIP part of the synchronization doesn't work and it can see a task after the whole address space has been demolished and traverse an already released mm->mmap list. This leads to use after free as properly caught up by KASAN report. Fix the issue by reseting mm->mmap so that MMF_OOM_SKIP synchronization is not needed anymore. The MMF_OOM_SKIP is not removed from exit_mmap yet but it acts mostly as an optimization now.

When we specify a large number for node in hugepages parameter, it may be parsed to another number due to truncation in this statement: node = tmp; For example, add following parameter in command line: hugepagesz=1G hugepages=4294967297:5 and kernel will allocate 5 hugepages for node 1 instead of ignoring it.

Thus, the first kmem_cache_destroy() call won't actually destroy it but will only decrease the refcount. This causes the test to fail.
