PMU uapi is likely to change in the future. Till the uapi is finalized, remove PMU from Xe. PMU can be re-added after uapi is finalized. v2: Include xe_drm.h in xe/tests/xe_dma_buf.c (Francois) Signed-off-by:

Those are just possible values for the comparison mask but they are not specific magic values. Let's keep them as examples in the documentation but remove them from the uAPI. Suggested-by:

The exec_queue_set_property feature was removed in a previous commit 0f1d88f2 ("drm/xe/uapi: Kill exec_queue_set_property") and is no longer usable, struct drm_xe_exec_queue_set_property does not exist anymore, so let's remove this. Reviewed-by:

remove the num_engines/instances members from drm_xe_wait_user_fence structure and add a exec_queue_id member Right now this is only checking if the engine list is sane and nothing else. In the end every operation with this IOCTL is a soft check. So, let's formalize that and only use this IOCTL to wait on the fence. exec_queue_id member will help to user space to get proper error code from kernel while in exec_queue reset Signed-off-by:

We don't use this suffix on any other registers, and it isn't part of the register's official name either, so drop it for consistency. While at it, move the register definition slightly so that it isn't separating RING_CMD_CCTL's definition from its fields. Reviewed-by:

The engine register header wound up with two definitions for RING_MAX_NONPRIV_SLOTS, likely due to a rebase mistake. Keep the definition that's in an appropriate place (i.e., with the FORCE_TO_NONPRIV register definition) and remove the other. Reviewed-by:

The idea being out-syncs can signal indicating all previous operations on the bind queue are complete. An example use case of this would be support for implementing vkQueueWaitIdle easily. All in-syncs are waited on before signaling out-syncs. This is implemented by forming a composite software fence of in-syncs and installing this fence in the out-syncs and exec queue last fence slot. The last fence must be added as a dependency for jobs on user exec queues as it is possible for the last fence to be a composite software fence (unordered, ioctl with zero bb or binds) rather than hardware fence (ordered, previous job on queue).

Currently scratch PTEs are write-enabled and points to a single scratch page. This has the side effect that buggy applications with out-of-bounds memory accesses may not notice the bad access since what's written may be read back. Instead use NULL PTEs as scratch PTEs. These always return 0 when reading, and writing has no effect. As a slight benefit, we can also use huge NULL PTEs. One drawback pointed out is that debugging may be hampered since previously when inspecting the content of the scratch page, it might be possible to detect writes to out-of-bound addresses and possibly also from where the out-of-bounds address originated. However since the scratch page-table structure is kept, it will be easy to add back the single RW-enabled scratch page under a debug define if needed. Also update the kerneldoc accordingly and move the function to create the scratch page-tables from xe_pt.c to xe_pt.h since it is accessing vm structure internals and this also makes it possible to make it static. v2: - Don't try to encode scratch PTEs larger than 1GiB. - Move xe_pt_create_scratch(), Update kerneldoc. v3: - Rebase.

Goals of this new xe_gt_freq component: 1. Detach sysfs controls and raw freq management from GuC SLPC. 2. Create a directory that could later be aligned with devfreq. 3. Encapsulate all the freq control in a single directory. Although we only have one freq domain per GT, already start with a numbered freq0 directory so it could be expanded in the future if multiple domains or PLL are needed. Note: Although in the goal #1, the raw freq management control is mentioned, this patch only starts by the sysfs control. The RP freq configuration and init freq selection are still under the guc_pc, but should be moved to this component in a follow-up patch. v2: - Add /tile# to the doc and remove unnecessary kobject_put (Riana) - s/ssize_t/int on some ret variables (Vinay) Cc: Sujaritha Sundaresan <sujaritha.sundaresan@intel.com> Cc: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Cc: Riana Tauro <riana.tauro@intel.com> Reviewed-by:
