ce->wa_bb_page is allocated only for graphics version 12. However

drm/i915/mtl: enable local stolen memory

As an integrated GPU, MTL does not have local memory and HAS_LMEM()
returns false.  However the platform's stolen memory is presented via
BAR2 (i.e., the BAR we traditionally consider to be the GMADR on IGFX)
and should be managed by the driver the same way that local memory is
on dgpu platforms (which includes setting the "lmem" bit on page table
entries).  We use the term "local stolen memory" to refer to this
model.

The major difference from the traditional BAR2 (GMADR) is that
the stolen area is mapped via the BAR2 while in the former BAR2 is an
aperture into the GTT VA through which access are made into stolen area.

BSPEC: 53098, 63830

v2:
1. dropped is_dsm_invalid, updated valid_stolen_size check from Lucas
(Jani, Lucas)
2. drop lmembar_is_igpu_stolen
3. revert to referring GFXMEM_BAR as GEN12_LMEM_BAR (Lucas)

v3:(Jani)
1. rename get_mtl_gms_size to mtl_get_gms_size
2. define register for MMIO address

v4:(Matt)
1. Use REG_FIELD_GET to read GMS value
2. replace the calculations with SZ_256M/SZ_8M

drm/i915/mtl: Define engine context layouts

The part of the media and blitter engine contexts that we care about for
setting up an initial state on MTL are nearly similar to DG2 (and PVC).
The difference being PRT_BB_STATE being replaced with NOP.

For render/compute engines, the part of the context images are nearly
the same, although the layout had a very slight change --- one POSH
register was removed and the placement of some LRI/noops adjusted
slightly to compensate.

idle even if there are contexts from apps Y, Z, ... waiting to run. A

drm/i915: Force DPLL calculation for TC ports after readout

We always allocate two DPLLs (TC and TBT) for TC ports. This
is because we can't know ahead of time wherher we need to put
the PHY into DP-Alt or TBT mode.

However during readout we can obviously only read out the state
of the DPLL that the port is actually using. Thus the state after
readout will not have both DPLLs populated.

We run into problems if during readout the TC port is in DP-Alt
mode, but we then perform a modeset on the port without going
through the full .compute_config() machinery, and during said
modeset the port cannot be switched back into DP-Alt mode and
we need to take the TBT fallback path. Such a modeset can
happen eg. due to cdclk reprogramming.

This wasn't a problem earlier because we did all the DPLL
calculations much later in the modeset. So even if flagged
a modeset very late we'd still have gone through the DPLL
calculations. But now all the DPLL calculations happen much
earlier and so we need to deal with it, or else we'll attempt
a modeset without a DPLL.

To guarantee that we always have both DPLLs fully cal/ulated
for TC ports force a full modeset computation during the
initial commit.

drm/i915: fix device info for devices without display

Commit 00c6cbfd4e8a ("drm/i915: move pipe_mask and cpu_transcoder_mask
to runtime info") moved the pipe_mask member from struct
intel_device_info to intel_runtime_info, but overlooked some of our
platforms initializing device info .display = {}. This is significant,
as pipe_mask is the single point of truth for a device having a display
or not; the platforms in question left pipe_mask to whatever was set for
the platforms they "inherit" from in the complex macro scheme we have.

Add new NO_DISPLAY macro initializing .__runtime.pipe_mask = 0, which
will cause the device info .display sub-struct to be zeroed in
intel_device_info_runtime_init(). A better solution (or simply audit of
proper use of HAS_DISPLAY() checks) is required before moving forward
with [1].

Also clear all the display related members in runtime info if there's no
display. The latter is a bit tedious, but it's for completeness at this
time, to ensure similar functionality as before.

drm/i915/gt: Restrict forced preemption to the active context

When we submit a new pair of contexts to ELSP for execution, we start a
timer by which point we expect the HW to have switched execution to the
pending contexts. If the promotion to the new pair of contexts has not
occurred, we declare the executing context to have hung and force the
preemption to take place by resetting the engine and resubmitting the
new contexts.

This can lead to an unfair situation where almost all of the preemption
timeout is consumed by the first context which just switches into the
second context immediately prior to the timer firing and triggering the
preemption reset (assuming that the timer interrupts before we process
the CS events for the context switch). The second context hasn't yet had
a chance to yield to the incoming ELSP (and send the ACk for the
promotion) and so ends up being blamed for the reset.

If we see that a context switch has occurred since setting the
preemption timeout, but have not yet received the ACK for the ELSP
promotion, rearm the preemption timer and check again. This is
especially significant if the first context was not schedulable and so
we used the shortest timer possible, greatly increasing the chance of
accidentally blaming the second innocent context.

doesn't followed regular mslice steering behavior.

 * Xe_HP SDV:  GAM ranges must always be steered to 0,0.  These
   registers share the regular steering control register (0xFDC) with
   other steering types

 * DG2:  GAM ranges must always be steered to 1,0.  GAM registers have a
   dedicated steering control register (0xFE0) so we can set the value
   once at startup and rely on implicit steering.  Technically the
   hardware default should already be set to 1,0 properly, but it never
   hurts to ensure that in the driver.

drm/amdgpu: add gang submit frontend v6

Allows submitting jobs as gang which needs to run on multiple engines at the
same time.

All members of the gang get the same implicit, explicit and VM dependencies. So
no gang member will start running until everything else is ready.

The last job is considered the gang leader (usually a submission to the GFX
ring) and used for signaling output dependencies.

Each job is remembered individually as user of a buffer object, so there is no

Jobs submitted as gang are never re-submitted in case of a GPU reset since this

drm/plane: Allocate planes with drm_universal_plane_alloc()

Provide drm_univeral_plane_alloc() to allocate and initialize a
plane. Code for non-atomic drivers uses this pattern. Convert them to
the new function. The modeset helpers contain a quirk for handling their
color formats differently. Set the flag outside plane allocation.

The new function is already deprecated to some extend. Drivers should
rather use drmm_univeral_plane_alloc() or drm_universal_plane_init().

drm/plane: Remove drm_plane_init()

Open-code drm_plane_init() and remove the function from DRM. The
implementation of drm_plane_init() is a simple wrapper around a call
to drm_universal_plane_init(), so drivers can just use that instead.

drm/amd/pm: Remove redundant check condition

V3:
[Why]:
  Since ASICs using smu v13_0_2 have called smu
.suspend before calling amdgpu_pm_sysfs_fini,
pm.dpm_enabled was already set to 0 when smu
.suspend was called. This makes it impossible
to delete all pm sys nodes.

[How]:
  Since all functions in amdgpu_pm_sysfs_fini
have their own condition checks, so the first
conditional check in amdgpu_pm_sysfs_fini can
be removed.

drm/amdgpu: Fixed psp fence and memory issues when removing amdgpu device

V3:
Fixed psp fence and memory issues for the asic
using smu v13_0_2 when removing amdgpu device.

[Why]:
1. psp_suspend->psp_free_shared_bufs->
       psp_ta_free_shared_buf->
           amdgpu_bo_free_kernel->
             ...->amdgpu_bo_release_notify->
                    amdgpu_fill_buffer
   psp will free vram memory used by psp when psp_suspend
   is called. But for the asic using smu v13_0_2, because
   psp_suspend is called before adev->shutdown is set to
   true when removing the first hive device, amdgpu fill_buffer
   will be called, which will cause fence issues when evicting
   all vram resources in amdgpu vram mgr_fini.
2. Since psp_hw_fini is not called after calling psp_suspend
   and psp_suspend only calls psp_ring_stop, the psp ring memory
   will not be released when amdgpu device is removed.

[How]:
1. Set shutdown to true before calling amdgpu_device_gpu_recover,
   then amdgpu_fill_buffer will not be called when psp_suspend is
   called.
2. Free psp ring memory in psp_sw_fini.

drm/amdgpu: Adjust removal control flow for smu v13_0_2

Adjust removal control flow for smu v13_0_2:
   During amdgpu uninstallation, when removing the first
device, the kernel needs to first send a mode1reset message
to all gpu devices. Otherwise, smu initialization will fail
the next time amdgpu is installed.

V2:
1. Update commit comments.
2. Remove the global variable amdgpu_device_remove_cnt
   and add a variable to the structure amdgpu_hive_info.
3. Use hive to detect the first removed device instead of
   a global variable.

V3:
 1. Update commit comments.
 2. Split a patch into multiple patches.
 3. The current patch does:
    a. Add a work mode of AMDGPU_RESET_FOR_DEVICE_REMOVE into
       the existing gpu recover path, which make all devices
       in hive list only have HW reset but no resume (except
       the base IP).
    b. Call AMDGPU_RESET_FOR_DEVICE_REMOVE and
       AMDGPU_NEED_FULL_RESET mode of amdgpu_device_gpu_recover
       in amdgpu_pci_remove when removing the first device in
       hive list.
    c. When removing the first device, the IP blocks keyword
       function call sequence is as follows:
.suspend->mode1reset->.resume(basic ip)->.hw_fini->.early_fini->.sw_fini.
   ^                           |
   |-<----------<---------<----|
The first three sequences are because of a call to
        amdgpu_device_gpu_recover. The three sequences will be
        executed in a loop until all devices in the hive list
        are iterated.
        The sequences starting from .hw_fini only apply to the
        first device. Since .suspend has been called before,
        except the resumed phase1 basic ip blocks, all other ip
        blocks .hw_fini of current device will do nothing.
     d. When removing other devices, the calling sequences is the
        same as legacy:
   .hw_fini -> .early_fini -> .sw_fini.
Since .suspend has been called when removing the first device,
        except the resumed phase1 basic ip blocks, all of other ip
        blocks .hw_fini of current device will do nothing.
