In order to detect duplicate implementations for the same workaround,
early in the implementation of RTP it was decided to error out even if
the values set are exactly the same. With the introduction of 18034896535
in commit 74671d23 ("drm/xe/xe2: Add workaround 18034896535"), LNL
stepping with graphics stepping A1 now gives the following error on
module load:

	xe 0000:00:02.0: [drm] *ERROR* GT0: [GT OTHER] \
	discarding save-restore reg e48c (clear: 00000200, set: 00000200,\
	masked: yes, mcr: yes): ret=-22

RTP may be improved in the future, but for now simply join the entries
like done with e.g. "1607297627, 1607030317, 1607186500".

We flush the rebind worker during the vm close phase, however in places
like preempt_fence_work_func() we seem to queue the rebind worker
without first checking if the vm has already been closed.  The concern
here is the vm being closed with the worker flushed, but then being
rearmed later, which looks like potential uaf, since there is no actual
refcounting to track the queued worker. We can't take the vm->lock here
in preempt_rebind_work_func() to first check if the vm is closed since
that will deadlock, so instead flush the worker again when the vm
refcount reaches zero.

v2:
 - Grabbing vm->lock in the preempt worker creates a deadlock, so
   checking the closed state is tricky. Instead flush the worker when
   the refcount reaches zero. It should be impossible to queue the
   preempt worker without already holding vm ref.

UAPI Changes:

- drm/i915/guc: Use context hints for GT frequency

    Allow user to provide a low latency context hint. When set, KMD
    sends a hint to GuC which results in special handling for this
    context. SLPC will ramp the GT frequency aggressively every time
    it switches to this context. The down freq threshold will also be
    lower so GuC will ramp down the GT freq for this context more slowly.
    We also disable waitboost for this context as that will interfere with
    the strategy.

    We need to enable the use of SLPC Compute strategy during init, but
    it will apply only to contexts that set this bit during context
    creation.

    Userland can check whether this feature is supported using a new param-
    I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission
    enabled platforms as they use SLPC for frequency management.

    The Mesa usage model for this flag is here -
    https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint

- drm/i915/gt: Enable only one CCS for compute workload

    Enable only one CCS engine by default with all the compute sices
    allocated to it.

    While generating the list of UABI engines to be exposed to the
    user, exclude any additional CCS engines beyond the first
    instance

    ***

    NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by
    default to mitigate a hardware bug. All the EUs will still remain
    usable, and all the userspace drivers have been confirmed to be able
    to dynamically detect the change in number of CCS engines and adjust.

    For the smaller percent of applications that get perf benefit from
    letting the userspace driver dispatch across all 4 CCS engines we will
    be introducing a sysfs control as a later patch to choose 4 CCS each
    with 25% EUs (or 50% if 2 CCS).

    NOTE: A regression has been reported at

    https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10895

    However Andi has been triaging the issue and we're closing in a fix
    to the gap in the W/A implementation:

housekeeping_setup() checks cpumask_intersects(present, online) to ensure
that the kernel will have at least one housekeeping CPU after smp_init(),
but this doesn't work if the maxcpus= kernel parameter limits the number of
processors available after bootup.

For example, a kernel with "maxcpus=2 nohz_full=0-2" parameters crashes at
boot time on a virtual machine with 4 CPUs.

Change housekeeping_setup() to use cpumask_first_and() and check that the
returned CPU number is valid and less than setup_max_cpus.

Another corner case is "nohz_full=0" on a machine with a single CPU or with
the maxcpus=1 kernel argument. In this case non_housekeeping_mask is empty
and tick_nohz_full_setup() makes no sense. And indeed, the kernel hits the
WARN_ON(tick_nohz_full_running) in tick_sched_do_timer().

And how should the kernel interpret the "nohz_full=" parameter? It should
be silently ignored, but currently cpulist_parse() happily returns the
empty cpumask and this leads to the same problem.

Change housekeeping_setup() to check cpumask_empty(non_housekeeping_mask)
and do nothing in this case.

Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not
include the boot CPU, which is no longer true after:

  08ae95f4 ("nohz_full: Allow the boot CPU to be nohz_full").

However after:

  aae17ebb ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work")

the kernel will crash at boot time in this case; housekeeping_any_cpu()
returns an invalid CPU number until smp_init() brings the first
housekeeping CPU up.

Change housekeeping_any_cpu() to check the result of cpumask_any_and() and
return smp_processor_id() in this case.

This is just the simple and backportable workaround which fixes the
symptom, but smp_processor_id() at boot time should be safe at least for
type == HK_TYPE_TIMER, this more or less matches the tick_do_timer_boot_cpu
logic.

There is no worry about cpu_down(); tick_nohz_cpu_down() will not allow to
offline tick_do_timer_cpu (the 1st online housekeeping CPU).

Now we have two flags for contiguous VRAM buffer allocation.
If the application request for AMDGPU_GEM_CREATE_VRAM_CONTIGUOUS,
it would set the ttm place TTM_PL_FLAG_CONTIGUOUS flag in the
buffer's placement function.

This patch will change the default behaviour of the two flags.

When we set AMDGPU_GEM_CREATE_VRAM_CONTIGUOUS
- This means contiguous is not mandatory.
- we will try to allocate the contiguous buffer. Say if the
  allocation fails, we fallback to allocate the individual pages.

When we setTTM_PL_FLAG_CONTIGUOUS
- This means contiguous allocation is mandatory.
- we are setting this in amdgpu_bo_pin_restricted() before bo validation
  and check this flag in the vram manager file.
- if this is set, we should allocate the buffer pages contiguously.
  the allocation fails, we return -ENOSPC.

v2:
  - keep the mem_flags and bo->flags check as is(Christian)
  - place the TTM_PL_FLAG_CONTIGUOUS flag setting into the
    amdgpu_bo_pin_restricted function placement range iteration
    loop(Christian)
  - rename find_pages with amdgpu_vram_mgr_calculate_pages_per_block
    (Christian)
  - Keep the kernel BO allocation as is(Christain)
  - If BO pin vram allocation failed, we need to return -ENOSPC as
    RDMA cannot work with scattered VRAM pages(Philip)

v3(Christian):
  - keep contiguous flag handling outside of pages_per_block
    calculation
  - remove the hacky implementation in contiguous flag error
    handling code

v4(Christian):
  - use any variable and return value for non-contiguous
    fallback

v5: rebase to amd-staging-drm-next branch

[WHY]
find_disp_cfg_idx_by_plane_id and find_disp_cfg_idx_by_stream_id returns
an array index and they return -1 when not found; however, -1 is not a
valid index number.

[HOW]
When this happens, call ASSERT(), and return a positive number (which is
fewer than callers' array size) instead.

This fixes 4 OVERRUN and 2 NEGATIVE_RETURNS issues reported by Coverity.
