All engines will be correctly initialized by the PF driver. Moreover, VF drivers can't access related engine registers. Signed-off-by:

VF drivers can only use GuC-based TLB invalidation, as they don't have access to the related registers. However, VFs shouldn't need any explicit TLB invalidation before enabling CTB communication, as there will be an implicit GGTT TLB invalidation issued by the GuC itself as part of MMIO-based action handling.

The VF drivers can't apply any workarounds as they don't have access to related registers. Since xe_wa_apply_tile_workarounds() function is not using RTP yet, we have to add early return. Signed-off-by:

There are no RTP save-restore actions applicable for VFs on current platforms. If any future platform will require some, we will need to update the RTP framework to support VF_READY or VF_ONLY actions. In the meantime, just skip all actions if we are running as VF driver. Signed-off-by:

We already maintain several flags that control the availability of features on a given device. Disable features, like PCODE or GuC PC or GSC, that do not apply to a VF device. Signed-off-by:

The OA ioctl's already have drm_dbg's which are sufficient to tell the user that OA is not supported on unsupported configurations (execlist mode and platform gen < 12). Having additional WARN_ON's for these during driver probe create unnecessary noise. Just remove these WARN_ON's. Suggested-by:

When UMD ask config to be updated, xe_oa_config_locked() was calling xe_oa_emit_oa_config() that would use stream->oa_config but that is only changed to the next oa_config after xe_oa_emit_oa_config() finish. So it was setting the same config for all DRM_XE_PERF_IOCTL_CONFIG calls. Cc: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by:

Even though ARAT interrupts are enabled by default, we still want to keep the code that enables them. But instead doing that in the CTB enabling step, move this code to the upload step, where we already setup few other registers related to GuC. Signed-off-by:

We should honor requested uncached mode also at the TTM layer. Otherwise, we risk losing updates to the memory based interrupts source or status vectors, as those require uncached memory. Signed-off-by:

Allow the OA buffer to be mmap'd to userspace. This is needed for the MMIO trigger use case.

The OA stream open perf op returns an fd with its own file_operations for the newly initialized OA stream. These file_operations allow userspace to enable or disable the stream, as well as apply a different metric configuration for the OA stream. Userspace can also poll for data availability. OA stream initialization is completed in this commit by enabling the OA stream. When sampling is enabled this starts a hrtimer which periodically checks for data availablility. v2: Use stream properties for stream reconfiguration with DRM_XE_PERF_IOCTL_CONFIG v3: Hold runtime_pm reference across oa buffer alloc/free v4: Fix 32 bit build Acked-by: -

Introduce add/remove config perf ops for OA. OA configurations consist of a set of event/counter select register address/value pairs. The add_config perf op validates and stores such configurations and also exposes them in the metrics sysfs. These configurations will be programmed to OA unit HW when an OA stream using a configuration is opened. The OA stream can also switch to other stored configurations. v2: Start config id's from 1 and other minor review comments (Umesh) v3: Add 32 bit build v4: Add kernel doc for non-static functions (Michal) Acked-by:

Normally only superuser/root can access perf counter data.

In Xe, the plan is to support multiple types of perf counter streams (OA is only one type of these streams). Rather than introduce NxM ioctls for these (N perf streams with M ioctl's per perf stream), we decide to multiplex these (N different stream types and the M ops for each of these stream types) through a single PERF ioctl. This multiplexing is the purpose of the PERF layer. In addition to PERF DRM ioctl's, another set of ioctl's on the PERF fd are defined. These are expected to be common to different PERF stream types and therefore defined at the PERF layer itself. v2: Add param_size to 'struct drm_xe_perf_param' (Umesh) v3: Rename 'enum drm_xe_perf_ops' to 'enum drm_xe_perf_ioctls' (Guy Zadicario) Add DRM_ prefix to ioctl names to indicate uapi names v4: Add 'enum drm_xe_perf_op' previously missed out (Guy Zadicario) v5: Squash the ops and PERF layer patches into a single patch (Umesh) Remove param_size from struct 'drm_xe_perf_param' (Umesh) v6: Add DRM_XE_PERF_IOCTL_STATUS v7: Add DRM_XE_PERF_IOCTL_INFO v8: Fix Copyright years, fix DRM_XE_PERF_TYPE_MAX, move '#include "xe_perf.h"' to xe_perf.c, add kernel doc (Michal) Acked-by:Guy Zadicario <gzadicario@habana.ai> Acked-by:

A temporary fixup was made in commit 24d0d98a ("drm/xe/xe2lpm: Fixup Wa_14020756599") due to limitations in the RTP infra. Now that RTP has support for OR condition that change can be removed. RTP now also supports checking any GT, so use that instead of the more specific xe_rtp_match_when_media2000() used in that commit. Reviewed-by:

One surprising factor of GRAPHICS_VERSION()/MEDIA_VERSION() matching for people adding new WAs is that it implicitly checks that the graphics/media IP under check is of that specific type and not that the device contains a media/graphics IP of that version. Add a new *_ANY_GT() variant that can be used in that case. Signed-off-by:

Some workarounds started to depend on different set of conditions where the action should be applied if any of them match. See e.g. commit 24d0d98a ("drm/xe/xe2lpm: Fixup Wa_14020756599"). Add XE_RTP_MATCH_OR that allows to implement a logical OR for the rules. Normal precedence applies: r1, r2, OR, r3 means (r1 AND r2) OR r3 The check is shortcut as soon as a set of conditions match. v2: Do not match on empty number of rules-other-than-OR evaluated Reviewed-by:
