2022-05-31drm/i915/pvc: Extract stepping information from PCI revidMatt Roper
For PVC, the base die and compute tile have separate stepping values that we need to track; we'll use the existing graphics_step field to represent the compute tile stepping and add a new 'basedie_step' field. Unlike past platforms, steppings for these components are represented by specific bitfields within the PCI revision ID, and we shouldn't make assumptions about the non-CT, non-BD bits staying 0. Let's update our stepping code accordingly.

2022-05-27drm/i915: Individualize fences before adding to dma_resv objNirmoy Das
_i915_vma_move_to_active() can receive > 1 fences for multiple batch buffers submission. Because dma_resv_add_fence() can only accept one fence at a time, change _i915_vma_move_to_active() to be aware of multiple fences so that it can add individual fences to the dma resv object. v6: fix multi-line comment. v5: remove double fence reservation for batch VMAs. v4: Reserve fences for composite_fence on multi-batch contexts and also reserve fence slots to composite_fence for each VMAs. v3: dma_resv_reserve_fences is not cumulative so pass num_fences. v2: make sure to reserve enough fence slots before adding.

2022-05-26drm/i915/gt: Add media freq factor to per-gt sysfsAshutosh Dixit
Expose new sysfs to program and retrieve media freq factor. Factor values of 0 (dynamic), 0.5 and 1.0 are supported via a u8.8 fixed point representation (corresponding to integer values of 0, 128 and 256 respectively). Media freq factor is converted to media_ratio_mode for GuC. It is programmed into GuC using H2G SLPC interface. It is retrieved from GuC through a register read. A cached media_ratio_mode is maintained to preserve set values across GuC resets.

When removing short term pins, I've changed the the batch buffer pinning for relocation to use __i915_vma_pin, because i915_gem_object_ggtt_pin_ww was destroying the old vma. This caused regressions, because the functions are not identical. Fix the regressions by calling i915_gem_object_ggtt_pin_ww() again on ggtt-only platforms, but only if the batch can be pinned without being moved.

2022-05-13drm/i915: Fix CFI violation with show_dynamic_id()Nathan Chancellor
When an attribute group is created with sysfs_create_group(), the ->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show() callback to kobj_attr_show(). kobj_attr_show() uses container_of() to get the ->show() callback from the attribute it was passed, meaning the ->show() callback needs to be the same type as the ->show() callback in 'struct kobj_attribute'. However, show_dynamic_id() has the type of the ->show() callback in 'struct device_attribute', which causes a CFI violation when opening the 'id' sysfs node under drm/card0/metrics. This happens to work because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast happens to allow the ->show() callback to still work. Change the type of show_dynamic_id() to match the ->show() callback in 'struct kobj_attributes' and update the type of sysfs_metric_id to match, which resolves the CFI violation.

2022-05-12i915/guc/reset: Make __guc_reset_context aware of guilty enginesUmesh Nerlige Ramappa
There are 2 ways an engine can get reset in i915 and the method of reset affects how KMD labels a context as guilty/innocent. (1) GuC initiated engine-reset: GuC resets a hung engine and notifies KMD. The context that hung on the engine is marked guilty and all other contexts are innocent. The innocent contexts are resubmitted. (2) GT based reset: When an engine heartbeat fails to tick, KMD initiates a gt/chip reset. All active contexts are marked as guilty and discarded. In order to correctly mark the contexts as guilty/innocent, pass a mask of engines that were reset to __guc_reset_context.
