On SRIOV, host driver can support FLR(function level reset) on individual VF within the hive which might bring the individual device back to normal without the necessary to execute the hive reset. If the FLR failed , host driver will trigger the hive reset, each guest VF will get reset notification before the real hive reset been executed. The VF device can handle the reset request individually in it's reset work handler. This change updated gpu recover sequence to skip reset other device in the same hive for SRIOV VF.

2021-12-13drm/mediatek: hdmi: Perform NULL pointer check for mtk_hdmi_confAngeloGioacchino Del Regno
In commit 41ca9caaae0b ("drm/mediatek: hdmi: Add check for CEA modes only") a check for CEA modes was added to function mtk_hdmi_bridge_mode_valid() in order to address possible issues on MT8167; moreover, with commit c91026a938c2 ("drm/mediatek: hdmi: Add optional limit on maximal HDMI mode clock") another similar check was introduced. Unfortunately though, at the time of writing, MT8173 does not provide any mtk_hdmi_conf structure and this is crashing the kernel with NULL pointer upon entering mtk_hdmi_bridge_mode_valid(), which happens as soon as a HDMI cable gets plugged in. To fix this regression, add a NULL pointer check for hdmi->conf in the said function, restoring HDMI functionality and avoiding NULL pointer kernel panics.

2021-12-13drm/i915: Move pipe/transcoder/abox masks under intel_device_info.displayVille Syrjälä
Collect the dipslay related mask under the display sub-structure in intel_device_info. Note that there is a slight change in behaviour in that we zero out .display entirely when !HAS_DISPLAY (aka. pipe_mask==0), so now we also zero out the other masks (although cpu_transocder_mask should already be zero of pipe_mask is zero). abox_mask is only used by the display core init when HAS_DISPLAY is true, so the actual behaviour of the system shouldn't change despite the zeroing of these masks. There is a lot more display stuff directly in device info that could be moved over. Maybe someone else will be inspired to do it...

2021-12-13drm/i915: Fix coredump of perma-pinned vmasThomas Hellström
When updating the error capture code and introducing vma snapshots, we introduced code to hold the vma in memory while capturing it, calling i915_active_acquire_if_busy(). Now that function isn't relevant for perma-pinned vmas and caused important vmas to be dropped from the coredump. Like for example the GuC log. Fix this by instead requiring those vmas to be pinned while capturing. Tested by running the initial subtests of the gem_exec_capture igt test with GuC submission enabled and verifying that a GuC log blob appears in the output.

2021-12-13drm/i915: Don't disable interrupts and pretend a lock as been acquired in ↵Sebastian Andrzej Siewior
__timeline_mark_lock(). This is a revert of commits d67739268cf0e ("drm/i915/gt: Mark up the nested engine-pm timeline lock as irqsafe") 6c69a45445af9 ("drm/i915/gt: Mark context->active_count as protected by timeline->mutex") 6dcb85a0ad990 ("drm/i915: Hold irq-off for the entire fake lock period") The existing code leads to a different behaviour depending on whether lockdep is enabled or not. Any following lock that is acquired without disabling interrupts (but needs to) will not be noticed by lockdep. This it not just a lockdep annotation but is used but an actual mutex_t that is properly used as a lock but in case of __timeline_mark_lock() lockdep is only told that it is acquired but no lock has been acquired. It appears that its purpose is just satisfy the lockdep_assert_held() check in intel_context_mark_active(). The other problem with disabling interrupts is that on PREEMPT_RT interrupts are also disabled which leads to problems for instance later during memory allocation. Add a CONTEXT_IS_PARKING bit to intel_engine_cs and set_bit/clear_bit it instead of mutex_acquire/mutex_release. Use test_bit in the two identified spots which relied on the lockdep annotation.

Adds drm support for the Unisoc's display subsystem. This is drm kms driver, this driver provides support for the application framework in Android, Yocto and more. Application framework can access Unisoc's display internal peripherals through libdrm or libkms, it's test ok by modetest (DRM/KMS test tool) and Android HWComposer. v4: - Move the devm_drm_dev_alloc to master_ops->bind function. - The managed drmm_mode_config_init() it is no longer necessary for drivers to explicitly call drm_mode_config_cleanup, so delete it. v5: - Remove subdir-ccflgas-y for Makefile. - Keep the selects sorted by alphabet for Kconfig.

2021-12-09drm/vmwgfx: Bump the minor versionZack Rusin
v2: Old userspace doesn't like 3.x.x and we'd like to keep it working, so lets just bump the minor version until we have no choice. With GEM, GL4.3, stats and removal of a lot of old code it's time to bump the minor version of the driver.

2021-12-09drm/vmwgfx: Remove usage of MOBFMT_RANGEZack Rusin
Using MOBFMT_RANGE in the early days of guest backed objects was a major performance win but that has changed a lot since. There's no more a performance reason to use MOBFMT_RANGE. The device can/will still profit from the pages being contiguous but marking them as MOBFMT_RANGE no longer matters. Benchmarks (e.g. heaven, valley) show that creating page tables for mob memory is actually faster than using mobfmt ranges.
