drm/i915: Eliminate IS_MTL_MEDIA_STEP Stepping-specific media behavior shouldn't be tied to MTL as a platform, but rather specifically to the Xe_LPM+ IP. Future non-MTL platforms may re-use this IP and will need to follow the exact same logic and apply the same workarounds. IS_MTL_MEDIA_STEP() is dropped in favor of IS_MEDIA_GT_IP_STEP, which checks the media IP version associated with a specific IP and also ensures that we're operating on the media GT, not the primary GT. v2: - Switch to the IS_GT_IP_STEP macro. v3: - Switch back to long-form IS_MEDIA_GT_IP_STEP. (Jani) v4: - Build IS_MEDIA_GT_IP_STEP on top of IS_MEDIA_GT_IP_RANGE and IS_MEDIA_STEP building blocks and name the parameters from/until rather than begin/fixed.. (Jani) v5: - Tweak macro comment wording. (Gustavo) - Add a check to catch NULL gt in IS_MEDIA_GT_IP_RANGE; this allows it to be used safely on i915->media_gt, which may be NULL on some platforms.

drm/i915: Eliminate IS_MTL_GRAPHICS_STEP Several workarounds are guarded by IS_MTL_GRAPHICS_STEP. However none of these workarounds are actually tied to MTL as a platform; they only relate to the Xe_LPG graphics IP, regardless of what platform it appears in. At the moment MTL is the only platform that uses Xe_LPG with IP versions 12.70 and 12.71, but we can't count on this being true in the future. Switch these to use a new IS_GFX_GT_IP_STEP() macro instead that is purely based on IP version. IS_GFX_GT_IP_STEP() is also GT-based rather than device-based, which will help prevent mistakes where we accidentally try to apply Xe_LPG graphics workarounds to the Xe_LPM+ media GT and vice-versa. v2: - Switch to a more generic and shorter IS_GT_IP_STEP macro that can be used for both graphics and media IP (and any other kind of GTs that show up in the future). v3: - Switch back to long-form IS_GFX_GT_IP_STEP macro. (Jani) - Move macro to intel_gt.h. (Andi) v4: - Build IS_GFX_GT_IP_STEP on top of IS_GFX_GT_IP_RANGE and IS_GRAPHICS_STEP building blocks and name the parameters from/until rather than begin/fixed.

drm/i915/xelpg: Call Xe_LPG workaround functions based on IP version Although some of our Xe_LPG workarounds were already being applied based on IP version correctly, others were matching on MTL as a base platform, which is incorrect. Although MTL is the only platform right now that uses Xe_LPG IP, this may not always be the case. If a future platform re-uses this graphics IP, the same workarounds should be applied, even if it isn't a "MTL" platform. We were also incorrectly applying Xe_LPG workarounds/tuning to the Xe_LPM+ media IP in one or two places; we should make sure that we don't try to apply graphics workarounds to the media GT and vice versa where they don't belong. A new helper macro IS_GT_IP_RANGE() is added to help ensure this is handled properly -- it checks that the GT matches the IP type being tested as well as the IP version falling in the proper range. Note that many of the stepping-based workarounds are still incorrectly checking for a MTL base platform; that will be remedied in a later patch. v2: - Rework macro into a slightly more generic IS_GT_IP_RANGE() that can be used for either GFX or MEDIA checks. v3: - Switch back to separate macros for gfx and media. (Jani) - Move macro to intel_gt.h.

drm/i915/gt: Batch TLB invalidations Invalidate TLB in batches, in order to reduce performance regressions. Currently, every caller performs a full barrier around a TLB invalidation, ignoring all other invalidations that may have already removed their PTEs from the cache. As this is a synchronous operation and can be quite slow, we cause multiple threads to contend on the TLB invalidate mutex blocking userspace. We only need to invalidate the TLB once after replacing our PTE to ensure that there is no possible continued access to the physical address before releasing our pages. By tracking a seqno for each full TLB invalidate we can quickly determine if one has been performed since rewriting the PTE, and only if necessary trigger one for ourselves. That helps to reduce the performance regression introduced by TLB invalidate logic.

drm/i915/gt: Re-do the intel-gtt split Re-do what was attempted in commit 7a5c922377b4 ("drm/i915/gt: Split intel-gtt functions by arch"). The goal of that commit was to split the handlers for older hardware that depend on intel-gtt.ko so i915 can be built for non-x86 archs, after some more patches. Other archs do not need intel-gtt.ko. Main issue with the previous approach: it moved all the hooks, including the gen8, which is used by all platforms gen8 and newer. Re-do the split moving only the handlers for gen < 6, which are the only ones calling out to the separate module. While at it do some minor cleanups: - Rename the prefix s/gen5_/gmch_/ to be more accurate what platforms are covered by intel_ggtt_gmch.c - Remove dead code for gen12 out of needs_idle_maps() - Remove TODO comment leftover - Re-order if/else ladder in ggtt_probe_hw() to keep newest platforms first v2: Add minor cleanups (Matt Roper) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220617230559.2109427-2-lucas.demarchi@intel.com

In addition to the problematic calls, we are moving the gmch-related functions to the new area.

drm/i915: Prepare for multiple GTs On a multi-tile platform, each tile has its own registers + GGTT space, and BAR 0 is extended to cover all of them. Up to four GTs are supported in i915->gt[], with slot zero shadowing the existing i915->gt0 to enable source compatibility with legacy driver paths. A for_each_gt macro is added to iterate over the GTs and will be used by upcoming patches that convert various parts of the driver to be multi-gt aware. Only the primary/root tile is initialized for now; the other tiles will be detected and plugged in by future patches once the necessary infrastructure is in place to handle them.

drm/i915/guc: add steering info to GuC register save/restore list GuC has its own steering mechanism and can't use the default set by i915, so we need to provide the steering information that the FW will need to save/restore registers while processing an engine reset. The GUC interface allows us to do so as part of the register save/restore list and it requires us to specify the steering for all multicast register, even those that would be covered by the default setting for cpu access. Given that we do not distinguish between registers that do not need steering and registers that are guaranteed to work the default steering, we set the steering for all entries in the guc list that do not require a special steering (e.g. mslice) to the default settings; this will cost us a few extra writes during engine reset but allows us to keep the steering logic simple.

drm/i915: Flush TLBs before releasing backing store We need to flush TLBs before releasing backing store otherwise userspace is able to encounter stale entries if a) it is not declaring access to certain buffers and b) it races with the backing store release from a such undeclared execution already executing on the GPU in parallel. The approach taken is to mark any buffer objects which were ever bound to the GPU and to trigger a serialized TLB flush when their backing store is released. Alternatively the flushing could be done on VMA unbind, at which point we would be able to ascertain whether there is potential a parallel GPU execution (which could race), but essentially it boils down to paying the cost of TLB flushes potentially needlessly at VMA unbind time (when the backing store is not known to be going away so not needed for safety), versus potentially needlessly at backing store relase time (since we at that point cannot tell whether there is anything executing on the GPU which uses that object). Thereforce simplicity of implementation has been chosen for now with scope to benchmark and refine later as required.

drm/i915: Add GT support for multiple types of multicast steering Although most of our multicast registers are replicated per-subslice, we also have a small number of multicast registers that are replicated per-l3 bank instead. For both types of multicast registers we need to make sure we steer reads of these registers to a valid instance. Ideally we'd like to find a specific instance ID that would steer reads of either type of multicast register to a valid instance (i.e., not fused off and not powered down), but sometimes the combination of part-specific fusing and the additional restrictions imposed by Render Power Gating make it impossible to find any overlap between the set of valid subslices and valid l3 banks. This problem will become even more noticeable on our upcoming platforms since they will be adding additional types of multicast registers with new types of replication and rules for finding valid instances for reads. To handle this we'll continue to pick a suitable subslice instance at driver startup and program this as the default (sliceid,subsliceid) setting in the steering control register (0xFDC). In cases where we need to read another type of multicast GT register, but the default subslice steering would not correspond to a valid instance, we'll explicitly re-steer the single read to a valid value, perform the read, and then reset the steering to it's "subslice" default. This patch adds the general functionality to prepare for this explicit steering of other multicast register types. We'll plug L3 bank steering into this in the next patch, and then add additional types of multicast registers when the support for our next upcoming platform arrives. v2: - Use entry->end==0 as table terminator. (Rodrigo) - Grab forcewake in wa_list_verify() now that we're using accessors that assume forcewake is already held. v3: - Fix loop condition when iterating over steering range tables.

drm/i915: Request watchdog infrastructure Prepares the plumbing for setting request/fence expiration time. All code is put in place but is never activated due yet missing ability to actually configure the timer. Outline of the basic operation: A timer is started when request is ready for execution. If the request completes (retires) before the timer fires, timer is cancelled and nothing further happens. If the timer fires request is added to a lockless list and worker queued. Purpose of this is twofold: a) It allows request cancellation from a more friendly context and b) coalesces multiple expirations into a single event of consuming the list. Worker locklessly consumes the list of expired requests and cancels them all using previous added i915_request_cancel(). Associated timeout value is stored in rq->context.watchdog.timeout_us. v2: * Log expiration. v3: * Include more information about user timeline in the log message. v4: * Remove obsolete comment and fix formatting.

drm/i915/uc: prefer intel_gt over i915 in GuC/HuC paths With our HW interface logic moving from i915 to gt and with GuC and HuC being part of the gt HW, it makes sense to use the intel_gt structure instead of i915 as our reference object in GuC/HuC paths.

drm/i915/uc: Move intel functions to intel_uc All the intel_uc_* can now be moved to work on the intel_uc structure for better encapsulation of uc-related actions. Note: I've introduced uc_to_gt instead of uc_to_i915 because the aim is to move everything to be gt-focused in the medium term, so we would've had to replace it soon anyway.

drm/i915/gt: Use intel_gt as the primary object for handling resets Having taken the first step in encapsulating the functionality by moving the related files under gt/, the next step is to start encapsulating by passing around the relevant structs rather than the global drm_i915_private.
