f7fe64ad0f drm/sched: Split free_job into own work item
Rather than call free_job and run_job in same work item have a dedicated
work item for each. This aligns with the design and intended use of work
queues.

v2:
   - Test for DMA_FENCE_FLAG_TIMESTAMP_BIT before setting
     timestamp in free_job() work item (Danilo)
v3:
  - Drop forward dec of drm_sched_select_entity (Boris)
  - Return in drm_sched_run_job_work if entity NULL (Boris)
v4:
  - Replace dequeue with peek and invert logic (Luben)
  - Wrap to 100 lines (Luben)
  - Update comments for *_queue / *_queue_if_ready functions (Luben)
v5:
  - Drop peek argument, blindly reinit idle (Luben)
  - s/drm_sched_free_job_queue_if_ready/drm_sched_free_job_queue_if_done (Luben)
  - Update work_run_job & work_free_job kernel doc (Luben)
v6:
  - Do not move drm_sched_select_entity in file (Luben)

a6149f0393 drm/sched: Convert drm scheduler to use a work queue rather than kthread
In Xe, the new Intel GPU driver, a choice has made to have a 1 to 1
mapping between a drm_gpu_scheduler and drm_sched_entity. At first this
seems a bit odd but let us explain the reasoning below.

1. In Xe the submission order from multiple drm_sched_entity is not
guaranteed to be the same completion even if targeting the same hardware
engine. This is because in Xe we have a firmware scheduler, the GuC,
which allowed to reorder, timeslice, and preempt submissions. If a using
shared drm_gpu_scheduler across multiple drm_sched_entity, the TDR falls
apart as the TDR expects submission order == completion order. Using a
dedicated drm_gpu_scheduler per drm_sched_entity solve this problem.

2. In Xe submissions are done via programming a ring buffer (circular
buffer), a drm_gpu_scheduler provides a limit on number of jobs, if the
limit of number jobs is set to RING_SIZE / MAX_SIZE_PER_JOB we get flow
control on the ring for free.

A problem with this design is currently a drm_gpu_scheduler uses a
kthread for submission / job cleanup. This doesn't scale if a large
number of drm_gpu_scheduler are used. To work around the scaling issue,
use a worker rather than kthread for submission / job cleanup.

v2:
  - (Rob Clark) Fix msm build
  - Pass in run work queue
v3:
  - (Boris) don't have loop in worker
v4:
  - (Tvrtko) break out submit ready, stop, start helpers into own patch
v5:
  - (Boris) default to ordered work queue
v6:
  - (Luben / checkpatch) fix alignment in msm_ringbuffer.c
  - (Luben) s/drm_sched_submit_queue/drm_sched_wqueue_enqueue
  - (Luben) Update comment for drm_sched_wqueue_enqueue
  - (Luben) Positive check for submit_wq in drm_sched_init
  - (Luben) s/alloc_submit_wq/own_submit_wq
v7:
  - (Luben) s/drm_sched_wqueue_enqueue/drm_sched_run_job_queue
v8:
  - (Luben) Adjust var names / comments

0da611a870 dma-buf: add dma_fence_timestamp helper
When a fence signals there is a very small race window where the timestamp
isn't updated yet. sync_file solves this by busy waiting for the
timestamp to appear, but on other ocassions didn't handled this
correctly.

Provide a dma_fence_timestamp() helper function for this and use it in
all appropriate cases.

Another alternative would be to grab the spinlock when that happens.

v2 by teddy: add a wait parameter to wait for the timestamp to show up, in case
   the accurate timestamp is needed and/or the timestamp is not based on
   ktime (e.g. hw timestamp)
v3 chk: drop the parameter again for unified handling

3bcc5209ba accel/ivpu: Make DMA allocations for MMU600 write combined
Previously using dma_alloc_wc() API we created cache coherent
(mapped as write-back) mappings.

Because we disable MMU600 snooping it was required to do costly
page walk and cache flushes after each page table modification.

With write-combined buffers it's possible to do a single write memory
barrier to flush write-combined buffer to memory which simplifies the
driver and significantly reduce time of map/unmap operations.

Mapping time of 255 MB is reduced from 2.5 ms to 500 us.

Use separate function as thread wake up condition. Use spin lock to assure

Profiling freq is a debug firmware feature. It switches default clock
to higher resolution for fine-grained and more accurate firmware task
profiling. We already configure it during boot up of VPU4.

Add debugfs knob and helpers per HW generation that allow to change it.
For vpu37xx the implementation is empty as profiling frequency can only
be changed on VPU4 or newer.

3198a62eb8 accel/ivpu: Add support for delayed D0i3 entry message
Currently the VPU firmware prepares for D0i3 every time the VPU
is entering D0i2 Idle state. This is not optimal as we might not
enter D0i3 every time we enter D0i2 Idle and this preparation
is quite costly.

This optimization moves D0i3 preparation to a dedicated
message sent from the host driver only when the driver is about
to enter D0i3 - this reduces power consumption and latency for
certain workloads, for example audio workloads that submit
inference every 10 ms.

The VPU needs non zero time to enter IDLE state after responding to
D0i3 entry message. If the driver does not wait for the VPU to enter
IDLE state it could cause warm boot failures.

Device and Host have a time synchronization mechanism that happens once
during boot when device is in SBL mode. After that, in mission-mode there
is no timesync. In an experiment after continuous operation, device time
drifted w.r.t. host by approximately 3 seconds per day. This drift leads
to mismatch in timestamp of device and Host logs. To correct this
implement periodic timesync in driver. This timesync is carried out via
QAIC_TIMESYNC_PERIODIC MHI channel.

bb8e97e26c accel/qaic: Enable 1 MSI fallback mode
Several virtualization use-cases either don't support 32 MultiMSIs
(Xen/VMware) or have significant drawbacks to their use (KVM's vIOMMU,
which is required to support 32 MSI, needs to allocate an alternate
system memory space for each device using vIOMMU (e.g. 8GB VM mem and
2 cards => 8 + 2 * 8 = 24GB host memory required)). Support these
cases by enabling a 1 MSI fallback mode.

Whenever all 32 MSIs requested are not available, a second request for
a single MSI is made. Its success is the initiator of single MSI mode.
This mode causes all interrupts generated by the device to be directed
to the 0th MSI (firmware >=v1.10 will do this as a response to the PCIe
MSI capability configuration). Likewise, all interrupt handlers for the
device are registered to the 0th MSI.

Since the DBC interrupt handler checks if the DBC is in use or if
there is any pending changes, the 'spurious' interrupts are
disregarded. If there is work to be done, the standard threaded IRQ
handler is dispatched.

On every interrupt, the MHI handler wakes up its threaded interrupt
handler, and attempts to wake any waiters for MHI state events.

Performance is within +-0.6% for test cases that typify real world
use. Larger differences ([-4,+132]%, avg +47%) exist for very simple
tasks (e.g. addition) compiled for single NSPs. It is assumed that the
small work and many interrupts typically cause contention (e.g. 16 NSPs
vs 4 CPUs), as evidenced by the standard deviation between runs also
decreasing (r=-0.48 between delta(Performace_test) and
delta(StdDev_test/Avg_test))

Additionally, people (me included) have misunderstood the PATH
property for being stable across reboots, but since a KMS object
ID is baked in there that's not the case. So PATH shouldn't be

0226ba393e drm: extract closefb logic in separate function
drm_mode_rmfb performs two operations: drop the FB from the
file_priv->fbs list, and make sure the FB is no longer used on a
plane.

In the next commit an IOCTL which only does so former will be
introduced, so let's split it into a separate function.

No functional change, only refactoring.

v2: no change

b70438004a drm/amdgpu: move buffer funcs setting up a level
Rather than doing this in the IP code for the SDMA paging
engine, move it up to the core device level init level.
This should fix the scheduler init ordering.

v2: drop extra parens
v3: drop SDMA helpers
v4: Added a Fixes tag because amdgpu dereferences an uninitialized
    scheduler without this patch, and this patch fixes this. (Luben)

56e449603f drm/sched: Convert the GPU scheduler to variable number of run-queues
The GPU scheduler has now a variable number of run-queues, which are set up at
drm_sched_init() time. This way, each driver announces how many run-queues it
requires (supports) per each GPU scheduler it creates. Note, that run-queues
correspond to scheduler "priorities", thus if the number of run-queues is set
to 1 at drm_sched_init(), then that scheduler supports a single run-queue,
i.e. single "priority". If a driver further sets a single entity per
run-queue, then this creates a 1-to-1 correspondence between a scheduler and
a scheduled entity.

drm/ci: add subset-1-gfx to LAVA_TAGS and adjust shards
The Collabora Lava farm added a tag called `subset-1-gfx` to half of
devices the graphics community use.

Lets use this tag so we don't occupy all the resources.

This is particular important because Mesa3D shares the resources with
DRM-CI and use them to do pre-merge tests, so it can block developers
from getting their patches merged.
