Check for media IP version instead of graphics since this is figuring out the media engines' configuration. Currently the only platform with non-matching graphics/media version is Meteor Lake: update the check in gen11_vdbox_has_sfc() so it considers not only version 12, but also any later version which then includes that platform.

2022-09-12drm/i915/mtl: Hook up interrupts for standalone mediaMatt Roper4-0/+31
Top-level handling of standalone media interrupts will be processed as part of the primary GT's interrupt handler (since primary and media GTs share an MMIO space, unlike remote tile setups). When we get down to the point of handling engine interrupts, we need to take care to lookup VCS and VECS engines in the media GT rather than the primary. There are also a couple of additional "other" instance bits that correspond to the media GT's GuC and media GT's power management interrupts; we need to direct those to the media GT instance as well.

When we hook up interrupts (in the next patch), interrupts for the media GT are still processed as part of the primary GT's interrupt flow. As such, we should share the same IRQ lock with the primary GT.

2022-09-12drm/i915/mtl: Add gsi_offset when emitting aux table invalidationMatt Roper3-9/+18
The aux table invalidation registers are a bit unique --- they're engine-centric registers that reside in the GSI register space rather than within the engines' regular MMIO ranges. That means that when issuing invalidation on engines in the standalone media GT, the GSI offset must be added to the regular MMIO offset for the invalidation registers.

2022-09-12drm/i915/uncore: Add GSI offset to uncoreMatt Roper3-4/+41
GT non-engine registers (referred to as "GSI" registers by the spec) have the same relative offsets on standalone media as they do on the primary GT, just with an additional "GSI offset" added to their MMIO address. If we store this GSI offset in the standalone media's intel_uncore structure, it can be automatically applied to all GSI reg reads/writes that happen on that GT, allowing us to re-use our existing GT code with minimal changes. Forcewake and shadowed register tables for the media GT (which will be added in a future patch) are listed as final addresses that already include the GSI offset, so we also need to add the GSI offset before doing lookups of registers in one of those tables. v2: - Add comment on raw_reg_*() macros explaining why we don't bother with GSI offsets in them.

Unmapping of the MMIO range can be done as a DRM-managed action, which will take care of the unmapping on device teardown and error paths. This will also ensure proper ordering with respect to other DRM-managed actions that we'll be using to clean up non-primary GTs in upcoming patches. We have not yet enabled any non-root GTs in the driver yet, so the kfree() of the GT structure is effectively dead code. When we do start enabling non-root GTs in upcoming patches, those are going to be using DRM-managed allocations tied to the device lifetime, so we don't need to explicitly free them (and kfree would be incorrect anyway).

2022-09-12drm/i915: Only hook up uncore->debug for primary uncoreMatt Roper4-17/+20
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.

As made mention of in commit 9f0ac028410f ("drm/print: rename drm_debug to __drm_debug to discourage use"), we shouldn't explicitly refer to __drm_debug in this context. So, use drm_debug_enabled() instead.

git://anongit.freedesktop.org/drm/drm-intel into drm-next UAPI Changes: - Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709" The intent of Wa_14015141709 was to inform us that userspace can no longer control object-level preemption as it has on past platforms (i.e., by twiddling register bit CS_CHICKEN1[0]). The description of the workaround in the spec wasn't terribly well-written, and when we requested clarification from the hardware teams we were told that on the kernel side we should also probably stop setting FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the hardware to honor the settings in per-context register CS_CHICKEN1. It turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a mistake; even though CS_CHICKEN1[0] is non-operational and useless to userspace, there are other bits in the register that do still work and might need to be adjusted by userspace in the future (e.g., to implement other workarounds that show up). If we don't set FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would not take effect.
