LNCF registers report wrong values when XE_FORCEWAKE_GT
only is held. Holding XE_FORCEWAKE_ALL ensures correct
operations on LNCF regs.

V2(Himal):
 - Use xe_force_wake_ref_has_domain

Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/1999

Some users apply PINNED and some don't when using pin_map(). The pin in
pin_map() should imply PINNED so just unconditionally apply it and clean
up all users.

With the idea of having more pinned objects using the blitter engine
where possible, during suspend/resume, mark the pinned objects which
can be done during the late phase once submission/migration has been
setup. Start out simple with lrc and page-tables from userspace.

v2:
 - s/early_restore/late_restore; early restore was way too bold with too
   many places being impacted at once.
v3:
 - Split late vs early into separate lists, to align with newly added
   apply-to-pinned infra.
v4:
 - Rebase.
v5:
 - Make sure we restore the late phase kernel_bo_present in igpu.

<title>drm/xe/rtp: Drop sentinels from arg to xe_rtp_process_to_sr()</title>

<id>cedf23842d7433eb32cb782a637bb870fb096a3b</id>
<content type='text'>
There's a mismatch on API: while xe_rtp_process_to_sr() processes
entries until an entry without name, the active tracking with
xe_rtp_process_ctx_enable_active_tracking() needs to use the number of
elements. The number of elements is taken everywhere using ARRAY_SIZE(),
but that will have one entry too many. This leads to the following
warning, as reported by lkp:

   drivers/gpu/drm/xe/xe_tuning.c: In function 'xe_tuning_dump':
&gt;&gt; include/drm/drm_print.h:228:31: warning: '%s' directive argument is null [-Wformat-overflow=]
     228 |         drm_printf((printer), "%.*s" fmt, (indent), "\t\t\t\t\tX", ##__VA_ARGS__)
         |                               ^~~~~~
   drivers/gpu/drm/xe/xe_tuning.c:226:17: note: in expansion of macro 'drm_printf_indent'
     226 |                 drm_printf_indent(p, 1, "%s\n", engine_tunings[idx].name);
         |                 ^~~~~~~~~~~~~~~~~

That's because it will still process the last entry when tracking the
active tunings. The same issue exists in the WAs. Change
xe_rtp_process_to_sr() to also take the number of elements so the empty
entry can be removed and the warning should go away. Fixing on the
active-tracking side would more fragile as the it would need a `- 1`
everywhere and continue to use a different approach for number of
elements.

Aside from the warning, it's a non-issue as there would always be enough
bits allocated and the last entry would never be active since
xe_rtp_process_to_sr() stops on the sentinel.

<title>drm/xe: Convert pre-GMDID IPs to struct xe_ip</title>
<updated>2025-03-05T20:17:00+00:00</updated>

<link rel='alternate' type='text/html' href='https://git.tavy.me/linux.git/commit/?id=f25e698d43fb279a4f168ef1f05d0ead98beffe9'/>
<id>f25e698d43fb279a4f168ef1f05d0ead98beffe9</id>
<content type='text'>
We have now a struct xe_ip to fully describe an IP, but we are only
using that for GMDID-based IPs.

For pre-GMDID IPs, we still describe release info (version and name) via
feature descriptors (struct xe_{graphics,media}_desc). Let's convert
those to use struct xe_ip.

With this, we have a uniform way of describing IPs in the xe driver
instead of having different approaches based on whether the IPs use
GMDIDs or not.

A nice side-effect of this change is that now we have an easy way to
lookup, in the source code, mappings between versions, names and
features for all supported IPs.

v2:
  - Store pointers to struct xe_ip instead xe_{graphics,media}_desc in
    struct xe_device_desc.

We have now a struct xe_ip to fully describe an IP, but we are only
using that for GMDID-based IPs.

For pre-GMDID IPs, we still describe release info (version and name) via
feature descriptors (struct xe_{graphics,media}_desc). Let's convert
those to use struct xe_ip.

With this, we have a uniform way of describing IPs in the xe driver
instead of having different approaches based on whether the IPs use
GMDIDs or not.

A nice side-effect of this change is that now we have an easy way to
lookup, in the source code, mappings between versions, names and

<title>drm/xe: Rename gmdid_map to xe_ip</title>

If we pay closer attention to struct gmdid_map, we will realize that it
is actually fully describing an IP (graphics or media): it contains
"release info" and "features info". The former is comprised of fields
"ver" and "name"; and the latter is done via member "ip", which is a
pointer to either struct xe_graphics_desc or xe_media_desc, and can be
reused across releases.

As such let's:

  * Rename struct gmdid_map to xe_ip.
  * Rename the field ver to verx100 to be consistent with the naming of
    members using that encoding of the version.
  * Rename the field "ip" to "desc" to make it clear that it is a
    pointer to a descriptor of features for the IP, since it will not
    contain *all* info (i.e. features + release info).

We sill have release info mapped into struct xe_{graphics,media}_desc
for pre-GMDID IPs. In an upcoming change we will handle that so that we
make a clear separation between "release info" and "feature info".

<title>drm/xe: Add a shrinker for xe bos</title>

Rather than relying on the TTM watermark accounting add a shrinker
for xe_bos in TT or system memory.

Leverage the newly added TTM per-page shrinking and shmem backup
support.

Although xe doesn't fully support WONTNEED (purgeable) bos yet,
introduce and add shrinker support for purgeable ttm_tts.

v2:
- Cleanups bugfixes and a KUNIT shrinker test.
- Add writeback support, and activate if kswapd.
v3:
- Move the try_shrink() helper to core TTM.
- Minor cleanups.
v4:
- Add runtime pm for the shrinker. Shrinking may require an active
  device for CCS metadata copying.
v5:
- Separately purge ghost- and zombie objects in the shrinker.
- Fix a format specifier - type inconsistency. (Kernel test robot).
v7:
- s/long/s64/ (Christian König)
- s/sofar/progress/ (Matt Brost)
v8:
- Rebase on Xe KUNIT update.
- Add content verifying to the shrinker kunit test.
- Split out TTM changes to a separate patch.
- Get rid of multiple bool arguments for clarity (Matt Brost)
- Avoid an error pointer dereference (Matt Brost)
- Avoid an integer overflow (Matt Auld)
- Address misc review comments by Matt Brost.
v9:
- Fix a compliation error.
- Rebase.
v10:
- Update to new LRU walk interface.
- Rework ghost-, zombie and purged object shrinking.
- Rebase.
v11:
- Use additional TTM helpers.
- Honor __GFP_FS and __GFP_IO
- Rebase.
v13:
- Use ttm_tt_setup_backup().
v14:
- Don't set up backup on imported bos.
v15:
- Rebase on backup interface changes.
