Multi Queue is a new mode of execution supported by the compute and
blitter copy command streamers (CCS and BCS, respectively). It is an
enhancement of the existing hardware architecture and leverages the
same submission model. It enables support for efficient, parallel
execution of multiple queues within a single context. All the queues
of a group must use the same address space (VM).
The new DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE execution queue
property supports creating a multi queue group and adding queues to
a queue group. All queues of a multi queue group share the same
context.
A exec queue create ioctl call with above property specified with value
DRM_XE_SUPER_GROUP_CREATE will create a new multi queue group with the
queue being created as the primary queue (aka q0) of the group. To add
secondary queues to the group, they need to be created with the above
property with id of the primary queue as the value. The properties of
the primary queue (like priority, timeslice) applies to the whole group.
So, these properties can't be set for secondary queues of a group.
Once destroyed, the secondary queues of a multi queue group can't be
replaced. However, they can be dynamically added to the group up to a
total of 64 queues per group. Once the primary queue is destroyed,
secondary queues can't be added to the queue group.
v2: Remove group->lock, fix xe_exec_queue_group_add()/delete()
function semantics, add additional comments, remove unused
group->list_lock, add XE_BO_FLAG_GGTT_INVALIDATE for cgp bo,
Assert LRC is valid, update uapi kernel doc.
(Matt Brost)
v3: Use XE_BO_FLAG_PINNED_LATE_RESTORE/USER_VRAM/GGTT_INVALIDATE
flags for cgp bo (Matt)

From: Niranjana Vishwanathapura @ 2025-11-21 3:51 UTC (permalink / raw)
To: intel-xe; +Cc: matthew.brost
Implement GuC commands and response along with the Context
Group Page (CGP) interface for multi queue support.
Ensure that only primary queue (q0) of a multi queue group
communicate with GuC. The secondary queues of the group only
need to maintain LRCA and interface with drm scheduler.
Use primary queue's submit_wq for all secondary queues of a multi
queue group. This serialization avoids any locking around CGP
synchronization with GuC.
v2: Fix G2H_LEN_DW_MULTI_QUEUE_CONTEXT value, add more comments
(Matt Brost)
v3: Minor code refactro, use xe_gt_assert

As this series isn't quite right for VF migration, I'd leave out any VF
migration changes. However I'd add a "FIXME: VF migration" in a follow
up + maybe open a Jira to track. I'd like to VF migration working for
multi-queue by the time we remove force probe for a device with
multi-queue, so have a bit of time and we discuss further on how to make
this work but I think it shouldn't be too bad.

We have helper for this now: xe_guc_ct_wake_waiters
Still need to scrub the entire code for 'wake_up_all(&guc->ct.wq)' and
fix those up but let's use this in new code.
Other than these mirror nit, lgtm.

Add support for queues of a multi queue group to set
their priority within the queue group by adding property
DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE_PRIORITY.
This is the only other property supported by secondary
queues of a multi queue group, other than
DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE.
v2: Add kernel doc for enum xe_multi_queue_priority,
Add assert for priority values, fix includes and
declarations (Matt Brost)
v3: update uapi kernel-doc (Matt Brost)

Only MULTI_QUEUE_PRIORITY property is valid for secondary queues of a
multi queue group. MULTI_QUEUE_PRIORITY only applies to multi queue group
queues. Detect invalid user queue property setting and return error.

This patch adds support for exec_queue set_property ioctl.
It is derived from the original work which is part of
https://patchwork.freedesktop.org/series/112188/
Currently only DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE_PRIORITY
property can be dynamically set.
v2: Check for and update kernel-doc which property this ioctl
supports (Matt Brost)

Support dynamic priority change for multi queue group queues via
exec queue set_property ioctl. Issue CGP_SYNC command to GuC through
the drm scheduler message interface for priority to take effect.
v2: Move is_multi_queue check to exec_queue layer and assert
is_multi_queue being set in guc submission layer (Matt Brost)
v3: Assert CGP_SYNC message length is valid (Matt Brost)

As all queues of a multi queue group use the primary queue of the group
to interface with GuC. Hence there is a dependency between the queues of
the group. So, when primary queue of a multi queue group is cleaned up,
also trigger a cleanup of the secondary queues also. During cleanup, stop
and re-start submission for all queues of a multi queue group to avoid
any submission happening in parallel when a queue is being cleaned up.
v2: Initialize group->list_lock, add fs_reclaim dependency, remove
unwanted secondary queues cleanup (Matt Brost)
v3: Properly handle cleanup of multi-queue group (Matt Brost)

Also discussed privately, I believe the agreement is teardown the group
on any individual job's timeout within the group. We maybe can leave
this part out until my series here [1] merges to avoid a conflict with
that series. Not huge deal as this feature won't be enabled for a bit as
all supported platforms are behind force probe.

To properly support soft light restore between batches
being arbitrated at the CFEG, PIPE_CONTROL instructions
have a new bit in the first DW, QUEUE_DRAIN_MODE. When
set, this indicates to the CFEG that it should only
drain the current queue.
Additionally we no longer want to set the CS_STALL bit
for these multi queue queues as this causes the entire
pipeline to stall waiting for completion of the prior
batch, preventing this soft light restore from occurring
between queues in a queue group.

We probably don't need to worry about converting in this function since
it's only used by an Xe2 workaround and will be removed completely once
https://patchwork.freedesktop.org/patch/689424/?series=157804&rev=2
lands. If you want to be safe, you could just make it an assertion for
!multi_queue since that should never be possible on Xe2.
Anyway, the changes look good overall so

Ok, will remove the change here and instead add an !multi_queue assert.

are killed.

Is the compute UMD ok with this? I really hope by the time multi-queue
is enabled in the KMD the compute UMD is only using faulting VMs. Not
blocker, we likely could actually fix preempt fence mode to avoid this
restriction, more something we need communicate to the UMDs teams / keep
an on eye if this becomes an issue.
Anyways patch LGTM:

The Dynamic Inhibit Context Switch (ICS) feature is not currently
supported on Xe3p with multi-queue feature as it conflicts with
that on the GuC side. Disable ICS to support multi-queue on Xe3p
platforms.

+/**
+ * DOC: Multi Queue Group
+ *
+ * Multi Queue Group is another mode of execution supported by the compute
+ * and blitter copy command streamers (CCS and BCS, respectively). It is
+ * an enhancement of the existing hardware architecture and leverages the
+ * same submission model. It enables support for efficient, parallel
+ * execution of multiple queues within a single shared context. The multi
+ * queue group functionality is only supported with GuC submission backend.
+ * All the queues of a group must use the same address space (VM).
+ *
+ * The DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE execution queue property
+ * supports creating a multi queue group and adding queues to a queue group.
+ *
+ * The XE_EXEC_QUEUE_CREATE ioctl call with above property with value field
+ * set to DRM_XE_MULTI_GROUP_CREATE, will create a new multi queue group with
+ * the queue being created as the primary queue (aka q0) of the group. To add
+ * secondary queues to the group, they need to be created with the above
+ * property with id of the primary queue as the value. The properties of
+ * the primary queue (like priority, time slice) applies to the whole group.
+ * So, these properties can't be set for secondary queues of a group.
+ *
+ * The hardware does not support removing a queue from a multi-queue group.
+ * However, queues can be dynamically added to the group. A group can have
+ * up to 64 queues. To support this, XeKMD holds references to LRCs of the
+ * queues even after the queues are destroyed by the user until the whole
+ * group is destroyed. The secondary queues hold a reference to the primary
+ * queue thus preventing the group from being destroyed when user destroys
+ * the primary queue. Once the primary queue is destroyed, secondary queues
+ * can't be added to the queue group, but they can continue to submit the
+ * jobs if the DRM_XE_MULTI_GROUP_KEEP_ACTIVE flag is set during the multi
+ * queue group creation.
+ *
+ * The queues of a multi queue group can set their priority within the group
+ * through the DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE_PRIORITY property.
+ * This multi queue priority can also be set dynamically through the
+ * XE_EXEC_QUEUE_SET_PROPERTY ioctl. This is the only other property
+ * supported by the secondary queues of a multi queue group, other than
+ * DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE.
+ *
+ * When GuC reports an error on any of the queues of a multi queue group,
+ * the queue cleanup mechanism is invoked for all the queues of the group
+ * as hardware cannot make progress on the multi queue context.

Subject: [PATCH v3 00/18] drm/xe: Multi Queue feature support
Multi Queue is a new mode of execution supported by the compute and blitter copy command streamers (CCS and BCS, respectively). It is an enhancement of the existing hardware architecture and leverages the same submission model. It enables support for efficient, parallel execution of multiple queues within a single context.
Add support for multi-queue feature and enable it on xe3p_xpc.
The associated IGT patch series is,
https://patchwork.freedesktop.org/series/156866/
The Compute UMD usecase is,
https://github.com/intel/compute-runtime/pull/862
Changes in v2:
- Rename multi_queue_enable_mask to multi_queue_engine_class_mask.
- Remove group->lock, fix function semantics, add additional comments,
add asserts, update uapi kernel-doc, move group->list_lock to right
patch, add XE_BO_FLAG_GGTT_INVALIDATE for cgp bo.
- Fix G2H_LEN_DW_MULTI_QUEUE_CONTEXT value.
- Add fs_reclaim lock dependency, add bspec ref, other minor cleanups.
Changes in v3:
- Add patch "drm/xe/xe3p: Disable GuC Dynamic ICS for Xe3p"
- Add patch "drm/xe/multi_queue: Reset GT upon CGP_SYNC failure"
- Code refactoring and kernel-doc update
- Assert CGP_SYNC message length is valid
- For CGP bo use PINNED_LATE_RESTORE/USER_VRAM/GGTT_INVALIDATE flags
- Properly handle cleanup of multi-queue group
