1e2803e565 drm/xe/display: move xe->display initialization to xe_display_probe()
The future goal is to have intel_display_device_probe() create struct
intel_display. As the first step, postpone xe->display initialization
right before that call. This is the same location as in i915.

There's a subtle functional change here: xe->display will now be
initialized only if xe->info.probe_display.

The xe_display_create() function becomes empty, and can be removed. Move
its documentation to xe_display_probe()

bc417e54e2 drm/xe: Enable configfs support for survivability mode
Enable survivability mode if supported and configfs attribute is set.
Enabling survivability mode manually is useful in cases where pcode does
not detect failure, validation and for IFR (in-field-repair).

To set configfs survivability mode attribute for a device

echo 1 > /sys/kernel/config/xe/0000:03:00.0/survivability_mode

The card enters survivability mode if supported

v2: add a log if survivability mode is enabled for unsupported
    platforms (Rodrigo)

3cbb651117 drm/xe/bo: Add a bo remove callback
On device unbind, migrate exported bos, including pagemap bos to
system. This allows importers to take proper action without
disruption. In particular, SVM clients on remote devices may
continue as if nothing happened, and can chose a different
placement.

The evict_flags() placement is chosen in such a way that bos that
aren't exported are purged.

For pinned bos, we unmap DMA, but their pages are not freed yet
since we can't be 100% sure they are not accessed.

All pinned external bos (not just the VRAM ones) are put on the
pinned.external list with this patch. But this only affects the
xe_bo_pci_dev_remove_pinned() function since !VRAM bos are
ignored by the suspend / resume functionality. As a follow-up we
could look at removing the suspend / resume iteration over
pinned external bos since we currently don't allow pinning
external bos in VRAM, and other external bos don't need any
special treatment at suspend / resume.

v2:
- Address review comments. (Matthew Auld).
v3:
- Don't introduce an external_evicted list (Matthew Auld)
- Add a discussion around suspend / resume behaviour to the
  commit message.
- Formatting fixes.
v4:
- Move dma-unmaps of pinned kernel bos to a dev managed
  callback to give subsystems using these bos a chance to
  clean them up. (Matthew Auld)

676da6ba5b drm/xe: Allow to inject error in early probe
Allow to test if driver behaves correctly when xe_pcode_probe_early()
fails. Note that this is not sufficient for testing survivability mode
as it's still required to read the hw to check for errors, which doesn't
happen on an injected failure.

To complete the early probe coverage, allow injection in the other
functions as well: xe_mmio_probe_early() and xe_device_probe_early().

86b5e0dbba drm/xe: Move survivability back to xe
Commit d40f275d96 ("drm/xe: Move survivability entirely to xe_pci")
moved the survivability handling to be done entirely in the xe_pci
layer. However there are some issues with that approach:

1) Survivability mode needs at least the mmio initialized, otherwise it
   can't really read a register to decide if it should enter that state
2) SR-IOV mode should be initialized, otherwise it's not possible to
   check if it's VF

Besides, as pointed by Riana the check for
xe_survivability_mode_enable() was wrong in xe_pci_probe() since it's
not a bool return.

Fix that by moving the initialization to be entirely in the xe_device
layer, with the correct dependencies handled: only after mmio and sriov
initialization, and not triggering it on error from
wait_for_lmem_ready(). This restores the trigger behavior before that
commit. The xe_pci layer now only checks for "is it enabled?",
like it's doing in xe_pci_suspend()/xe_pci_remove(), etc.

d40f275d96 drm/xe: Move survivability entirely to xe_pci
There's an odd split between xe_pci.c and xe_device.c wrt
xe_survivability: it's initialized by xe_device, but then finalized by
xe_pci. Move it entirely to the outer layer, xe_pci, so it controls
the flow entirely.

This also allows to stop ignoring some of the errors. E.g.: if there's
an -ENOMEM, it shouldn't continue as if it survivability had been
enabled.

One change worth mentioning is that if "wait for lmem" fails, it will
also check the pcode status to decide if it should enter or not in
survivability mode, which it was not doing before. The bit from pcode
for that decision should remain the same after lmem failed
initialization, so it should be fine.

00f6a86c3c drm/xe: Move drm_dev_unplug() out of display function
This is not really display-related and needed for any sequence on driver
removal that has to interact with drm_dev_enter()/drm_dev_exit().
Just remove xe_device_remove_display() and inline it in the single
caller to make clear this is not done only for display.

ff6cd29b69 drm/xe: Cleanup unwind of gt initialization
The only thing in xe_gt_remove() that really needs to happen on the
device remove callback is the xe_uc_remove(). That's because of the
following call chain:

	xe_gt_remove()
	  xe_uc_remove()
	    xe_gsc_remove()
	      xe_gsc_proxy_remove()

Move xe_gsc_proxy_remove() to be handled as a xe_device_remove_action,
so it's recorded when it should run during device removal. The rest can
be handled normally by devm infra.

Besides removing the deep call chain above, xe_device_probe() doesn't
have to unwind the gt loop and it's also more in line with the
xe_device_probe() style.

776e3b502b drm/xe: Add callback support for driver remove
xe device probe uses devm cleanup in most places. However there are a
few cases where this is not possible: when the driver interacts with
component add/del. In that case, the resource group would be cleanup
while the entire device resources are in the process of cleanup.  One
example is the xe_gsc_proxy and display using that to interact with mei
and audio.

Add a callback-based remove so the exception doesn't make the probe
use multiple error handling styles.

v2: Change internal API to mimic the devm API. This will make it easier
    to migrate in future when devm can be used.

9c9dc9ba4a drm/xe/pxp: Fail the load if PXP fails to initialize
The PXP implementation mimics the i915 approach of allowing the load
to continue even if PXP init has failed. On Xe however we're taking an
harder stance on boot error and only allowing the load to complete if
everything is working, so update the code to fail if anything goes wrong
during PXP init.

While at it, update the return code in case of PXP not supported to be 0
instead of EOPNOTSUPP, to follow the standard of functions called by
xe_device_probe where every non-zero value means failure.

Now that interrupts are disabled for xe_display_init_noaccel,
both xe_display_init_noirq and xe_display_init_noaccel run in the same
context.

This means that we can get rid of the 3 different init calls. Without
interrupts, nothing is touching display up to this point.
Unify those 3 early display calls into a single xe_display_init_early(),
this makes the init sequence cleaner, and display less tangled during
init.

75d37750a7 drm/xe/mmap: Add mmap support for PCI memory barrier
In order to avoid having userspace to use MI_MEM_FENCE,
we are adding a mechanism for userspace to generate a
PCI memory barrier with low overhead (avoiding IOCTL call
as well as writing to VRAM will adds some overhead).

This is implemented by memory-mapping a page as uncached
that is backed by MMIO on the dGPU and thus allowing userspace
to do memory write to the page without invoking an IOCTL.
We are selecting the MMIO so that it is not accessible from
the PCI bus so that the MMIO writes themselves are ignored,
but the PCI memory barrier will still take action as the MMIO
filtering will happen after the memory barrier effect.

When we detect special defined offset in mmap(), We are mapping
4K page which contains the last of page of doorbell MMIO range
to userspace for same purpose.

For user to query special offset we are adding special flag in
mmap_offset ioctl which needs to be passed as follows,
struct drm_xe_gem_mmap_offset mmo = {
        .handle = 0, /* this must be 0 */
        .flags = DRM_XE_MMAP_OFFSET_FLAG_PCI_BARRIER,
};
igt_ioctl(fd, DRM_IOCTL_XE_GEM_MMAP_OFFSET, &mmo);
map = mmap(NULL, size, PROT_WRITE, MAP_SHARED, fd, mmo);

40fbc59e7c drm/xe/vf: Don't check has flat ccs in bios on VF
Don't check for flat ccs from VF-level as VF does not have direct
access to the register.

If the BIOS disables FlatCCS support (a use-case that will nearly never
be used) and the has_flat_ccs flag is set, there shouldn't be
any functional impact. The hardware will drop writes to the CCS region,
and reads from the CCS region will always return 0.
For the native case, the flag is disabled if the BIOS disables
it to avoid unnecessary overhead in buffer object (BO) creation
and migration.

da889070be drm/xe/irq: Separate MSI and MSI-X flows
A new flow is added for devices that support MSI-X:
- MSI-X vector 0 is used for GuC-to-host interrupt
- MSI-X vector 1 (aka default MSI-X) is used for HW engines

The default MSI-X will be passed to the HW engines in a subsequent
patch.
