Merge v7.0-rc7 into drm-next
Thomas Zimmermann needs 2f42c1a616 ("drm/ast: dp501: Fix
initialization of SCU2C") for drm-misc-next.
Conflicts:
- drivers/gpu/drm/amd/display/dc/hwss/dcn401/dcn401_hwseq.c
Just between e927b36ae1 ("drm/amd/display: Fix NULL pointer
dereference in dcn401_init_hw()") and it's cherry-pick that confused
git.
- drivers/gpu/drm/amd/pm/swsmu/smu11/smu_v11_0.c
Deleted in 6b0a611628 ("drm/amd/pm: Unify version check in SMUv11")
but some cherry-picks confused git. Same for v12/v14.

xe_device_declare_wedged() runs in the DMA-fence signaling path, where
GFP_KERNEL memory allocations are not allowed. However, registering
xe_device_wedged_fini via drmm_add_action_or_reset() triggers a
GFP_KERNEL allocation.
Fix this by deferring the registration of xe_device_wedged_fini until
late in the driver load sequence. Additionally, drop the wedged PM
reference only if the device is actually wedged in
xe_device_wedged_fini.

XA, new pat_index introduced post xe3p_lpg, is memory shared between the
CPU and GPU is treated differently from other GPU memory when the Media
engine is power-gated.
XA is *always* flushed, like at the end-of-submssion (and maybe other
places), just that internally as an optimisation hw doesn't need to make
that a full flush (which will also include XA) when Media is
off/powergated, since it doesn't need to worry about GT caches vs Media
coherency, and only CPU vs GPU coherency, so can make that flush a
targeted XA flush, since stuff tagged with XA now means it's shared with
the CPU. The main implication is that we now need to somehow flush non-XA
before freeing system memory pages, otherwise dirty cachelines could be
flushed after the free (like if Media suddenly turns on and does a full
flush)
V4: Add comments for L2 flush path
V3(Thomas/MattA/MattR): Restrict userptr with non-xa, then no need to
flush manually
V2(MattA): Expand commit description

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU. For more details see the Link tag below.
In order to keep alloc_workqueue() behavior identical, explicitly request
WQ_PERCPU.

clangd reports many "unused header" warnings throughout the Xe driver.
Start working to clean this up by removing unnecessary includes in our
.c files and/or replacing them with explicit includes of other headers
that were previously being included indirectly.
By far the most common offender here was unnecessary inclusion of
xe_gt.h. That likely originates from the early days of xe.ko when
xe_mmio did not exist and all register accesses, including those
unrelated to GTs, were done with GT functions.
There's still a lot of additional #include cleanup that can be done in
the headers themselves; that will come as a followup series.

Prior to lmem init check, driver is waiting for the pcode uncore_init
status. uncore_init status will be flagged after the complete boot and
initialization of the SoC by the pcode. uncore_init confirms that lmem
init and mmio unblock has been already completed.
It makes no sense to check for lmem init after the pcode uncore_init
check. So change the wait for lmem init check into an assert which
confirms lmem init is set.

(cherry picked from commit d69d3636f5)
Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com>
When we're initially enabling driver support for a new platform/IP, we
usually implement all workarounds documented in the WA database in the
driver. Many of those workarounds are restricted to early steppings
that only showed up in pre-production hardware (i.e., internal test
chips that are not available to the general public). Since the
workarounds for early, pre-production steppings tend to be some of the
ugliest and most complicated workarounds, we generally want to eliminate
them and simplify the code once the platform has launched and our
internal usage of those pre-production parts have been phased out.
Let's add a flag to the device info that tracks which platforms still
have support for pre-production workarounds for so that we can print a
warning and taint if someone tries to load the driver on a
pre-production part for a platform without pre-production workarounds.
This will help our internal users understand the likely problems they'll
encounter if they try to load the driver on an old pre-production
device.
The Xe behavior here is similar to what we've done for many years on
i915 (see intel_detect_preproduction_hw()), except that instead of
manually coding up ranges of device steppings that we believe to be
pre-production hardware, Xe will use the hardware's own production vs
pre-production fusing status, which we can read from the FUSE2 register.
This fuse didn't exist on older Intel hardware, but should be present on
all platforms supported by the Xe driver.
Going forward, let's set the expectation that we'll start looking into
removing pre-production workarounds for a platform around the time that
platforms of the next major IP stepping are having their force_probe
requirement lifted. This timing is just a rough guideline; there may be
cases where some instances of pre-production parts are still being
actively used in CI farms, internal device pools, etc. and we'll need to
wait a bit longer for those to be swapped out.
v2:
- Fix inverted forcewake check
v3:
- Invert flag and add it to the platforms on which we still have
pre-prod workarounds. (Jani, Lucas)
v4:
- Avoid checking pre-production on VF since they don't have access to
the FUSE2 register.

Corrected various spelling mistakes and typos in multiple
files under the Xe directory. These fixes improve clarity
and maintain consistency in documentation.

to the driver name
- of -> for
- Typical -> Typically

If the primary is GT is disabled via configfs, we can't read the GT
registers that would tell us whether the BIOS has disabled FlatCCS on a
platform that would otherwise have it; we'll just proceed as if the
FlatCCS is still enabled. This is similar to the situation seen by
SRIOV VFs and doesn't cause any functional problems since the hardware
will simply drop writes to the CCS region and reads will always come
back as 0 (indicating uncompressed data). We'll simply miss out on the
chance to avoid some unnecessary overhead during BO creation and
migration.

If the primary GT is disabled via configfs, GT-side L2 and TD cache
flushes are unnecessary since nothing is using/filling these caches.

The previous timeout of 500us seems to be too small; panning the map in
the Roll20 VTT in Firefox on a KDE/Wayland desktop reliably triggered
timeouts within a few seconds of usage, causing the monitor to freeze
and the following to be printed to dmesg:
[Jul30 13:44] xe 0000:03:00.0: [drm] *ERROR* GT0: Global invalidation timeout
[Jul30 13:48] xe 0000:03:00.0: [drm] *ERROR* [CRTC:82:pipe A] flip_done timed out
I haven't hit a single timeout since increasing it to 1000us even after
several multi-hour testing sessions.
