The Makefile for xe asks us to keep the lists of object files sorted:

Reshuffle the lists into the correct sort order. That was done by

GuC firmware counts received VF configuration KLVs and may start
validation of the complete VF config even if some resources where
unprovisioned in the meantime, leading to unexpected errors like:
$ echo 1 | sudo tee /sys/kernel/debug/dri/0000:00:02.0/gt0/vf1/contexts_quota
$ echo 0 | sudo tee /sys/kernel/debug/dri/0000:00:02.0/gt0/vf1/contexts_quota

tee: '/sys/kernel/debug/dri/0000:00:02.0/gt0/vf1/ggtt_quota': Input/output error
To mitigate this problem trigger explicit VF config reset after
unprovisioning any of the critical resources (GGTT, context or
doorbell IDs) that GuC is monitoring.

It turned out that GuC validates VF configuration immediately
after receiving "some" set of configuration KLVs and complains
if one of the critical, from GuC understanding, resource is left
unprovisioned, even if PF should be still allowed to make late VF
config adjustments, since VF was not yet started.
This issue was discovered after we decided to asynchronously
re-send configuration KLVs after GT reset/resume, as then fair
VF auto-provisioning could already allocate some of the resources,
which was a prerequiste for sending those config KLVs:
# fair GGTT provisioning

This reverts commit 835443da6f50d9516b58bba5a4fdf9e563d961c7.
Logging with gt_err() causes CI to detect an error even in cases
of intentional error injection. Since real errors are already
correctly reported by CI, this additional message is unnecessary.
Furthermore, a GT wedge is already being logged elsewhere, so
instead of adjusting the log level, revert the above mentioned
commit to prevent redundant error reporting.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and debugfs updates from Greg KH:
"Here is the big set of driver core and debugfs updates for 6.14-rc1.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at
least one user that does have a regression with these, but Al is
working on tracking down the fix for it. In my use (and everyone
else's linux-next use), it does not seem like a big issue at the
moment.
Here's a short list of the things in here:
- driver core rust bindings for PCI, platform, OF, and some i/o
functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing
things in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon""

Currently we just define the display tracepoints with
TRACE_SYSTEM i915. However the code gets included separately
in i915 and xe, and now both modules are competing for the
same tracepoints. Apparently whichever module is loaded first
gets the tracepoints and the other guy is left with nothing.
Give each module its own set of display tracepoints so that
things work even when both modules are loaded.

Using the plane->state pointer in the tracepoints is incorrect
as technically a different state could already have been swapped
in (though in reality that is currently prevented by the stall
hacks in the commit machinery). But let's not leave such footguns

I'm seeing underruns with these 64bpp YUV formats on TGL.
The weird details:
- only happens on pipe B/C/D SDR planes, pipe A SDR planes
seem fine, as do all HDR planes
- somehow CDCLK related, higher CDCLK allows for bigger plane
with these formats without underruns. With 300MHz CDCLK I
can only go up to 1200 pixels wide or so, with 650MHz even
a 3840 pixel wide plane was OK
- ICL and ADL so far appear unaffected
So not really sure what's the deal with this, but bspec does
state "64-bit formats supported only on the HDR planes" so
let's just drop these formats from the SDR planes. We already
disallow 64bpp RGB formats.

When converting to folios the cleanup path of shmem_get_pages() was
missed. When a DMA remap fails and the max segment size is greater than
PAGE_SIZE it will attempt to retry the remap with a PAGE_SIZEd segment
size. The cleanup code isn't properly using the folio apis and as a
result isn't handling compound pages correctly.
v2 -> v3:
(Ville) Just use shmem_sg_free_table() as-is in the failure path of
shmem_get_pages(). shmem_sg_free_table() will clear mapping unevictable
but it will be reset when it retries in shmem_sg_alloc_table().
v1 -> v2:
(Ville) Fixed locations where we were not clearing mapping unevictable.

Boot Survivability is a software based workflow for recovering a system
in a failed boot state. Here system recoverability is concerned with
recovering the firmware responsible for boot.
This is implemented by loading the driver with bare minimum (no drm card)
to allow the firmware to be flashed through mei-gsc and collect telemetry.
The driver's probe flow is modified such that it enters survivability mode
when pcode initialization is incomplete and boot status denotes a failure.
In this mode, drm card is not exposed and presence of survivability_mode
entry in PCI sysfs is used to indicate survivability mode and
provide additional information required for debug
This patch adds initialization functions and exposes admin
readable sysfs entries
The new sysfs will have the below layout
/sys/bus/.../bdf
├── survivability_mode
v2: reorder headers

Add the const qualifier to all the ctl_tables in the tree except for
watchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls,
loadpin_sysctl_table and the ones calling register_net_sysctl (./net,
drivers/inifiniband dirs). These are special cases as they use a
registration function with a non-const qualified ctl_table argument or
modify the arrays before passing them on to the registration function.
Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as the arrays would reside in .rodata.
This is made possible after commit 78eb4ea25cd5 ("sysctl: treewide:

Commit 70fb86a85dc9 ("drm/xe: Revert some changes that break a mesa
debug tool") partially reverted some changes to workaround breakage
caused to mesa tools. However, in doing so it also broke fetching the
GuC log via debugfs since xe_print_blob_ascii85() simply bails out.
The fix is to avoid the extra newlines: the devcoredump interface is
line-oriented and adding random newlines in the middle breaks it. If a
tool is able to parse it by looking at the data and checking for chars
that are out of the ascii85 space, it can still do so. A format change
that breaks the line-oriented output on devcoredump however needs better
coordination with existing tools.

Having the exec queue snapshot inside a "GuC CT" section was always
wrong. Commit c28fd6c358db ("drm/xe/devcoredump: Improve section
headings and add tile info") tried to fix that bug, but with that also
broke the mesa tool that parses the devcoredump, hence it was reverted
in commit 70fb86a85dc9 ("drm/xe: Revert some changes that break a mesa
debug tool").
With the mesa tool also fixed, this can propagate as a fix on both
kernel and userspace side to avoid unnecessary headache for a debug
feature.

When running igt@gem_exec_balancer@individual for multiple iterations,
it is seen that the delta busyness returned by PMU is 0. The issue stems
from a combination of 2 implementation specific details:
1) gt_park is throttling __update_guc_busyness_stats() so that it does
not hog PCI bandwidth for some use cases. (Ref: 59bcdb564b3ba)
2) busyness implementation always returns monotonically increasing
counters. (Ref: cf907f6d29421)
If an application queried an engine while it was active,
engine->stats.guc.running is set to true. Following that, if all PM
wakeref's are released, then gt is parked. At this time the throttling
of __update_guc_busyness_stats() may result in a missed update to the
running state of the engine (due to (1) above). This means subsequent
calls to guc_engine_busyness() will think that the engine is still
running and they will keep updating the cached counter (stats->total).
This results in an inflated cached counter.
Later when the application runs a workload and queries for busyness, we
return the cached value since it is larger than the actual value (due to
(2) above)
All subsequent queries will return the same large (inflated) value, so
the application sees a delta busyness of zero.
Fix the issue by resetting the running state of engines each time
intel_guc_busyness_park() is called.
v2: (Rodrigo)
- Use the correct tag in commit message
- Drop the redundant wakeref check in guc_engine_busyness() and update
commit message

The steering code needs to know slice/subslice counts and this
information should be retrieved from the hwconfig table. However,
earlier platforms don't have it, hence the KMD has a fallback path.
Newer platforms really should have the entries and if they are missing
that is a bug that needs to be fixed in the table.
So update the complaint to be an error on newer platforms and remove
it completely for older ones that we know are bad (but are not POR for
the Xe driver anyway). Also, re-word the message a little to make it
clearer what the issue is.

Since the GuC is reset during GT reset, we need to re-send the
entire SR-IOV provisioning configuration to the GuC. But since
this whole configuration is protected by the PF master mutex and
we can't avoid making allocations under this mutex (like during
LMEM provisioning), we can't do this reprovisioning from gt-reset
path if we want to be reclaim-safe. Move VFs reprovisioning to a
async worker that we will start from the gt-reset path.

timing generators and can be used as a reference for synchronization.
We have observed that we are inheriting from GOP a display configuration
with the CMTG enabled. Because our driver doesn't currently implement
any CMTG sequences, the CMTG ends up still enabled after our driver
takes over.
We need to make sure that the CMTG is not enabled if we are not going to
use it. For that, let's add a partial implementation in our driver that
only cares about disabling the CMTG if it was found enabled during
initial hardware readout. In the future, we can also implement sequences
for using the CMTG if that becomes a needed feature.
For now, we only deal with cases when it is possible to disable the CMTG
without requiring a modeset. For earlier display versions, we simply
skip if we find the CMTG enabled and we can't disable it without a
proper modeset. In the future, we need to properly handle that case.
v2:
- DG2 does not have the CMTG. Update HAS_CMTG() accordingly.
- Update logic to force disabling of CMTG only for initial commit.
v3:
- Add missing changes for v2 that were staged but not committed.
v4:
- Avoid if/else duplication in intel_cmtg_dump_state() by using "n/a"
for CMTG B enabled/disabled string for platforms without it. (Jani)
- Prefer intel_cmtg_readout_hw_state() over intel_cmtg_readout_state().
(Jani)
- Use display struct instead of i915 as first parameter for
TRANS_DDI_FUNC_CTL2(). (Jani)
- Fewer continuation lines in variable declaration/initialization for
better readability. (Jani)
- Coding style improvements. (Jani)
- Use drm_dbg_kms() instead of drm_info() for logging the disabling
of the CMTG.
- Make struct intel_cmtg_state entirely private to intel_cmtg.c.
v5:
- Do the disable sequence as part of the sanitization step after
hardware readout instead of initial modeset commit. (Jani)
- Adapt to commit 15133582465f ("drm/i915/display: convert global state
to struct intel_display") by using a display struct instead of i915
as argument for intel_atomic_global_obj_init().
v6:
- Do not track CMTG state as a global state. (Ville)
- Simplify the driver logic by only disabling the CMTG only on cases
when a modeset is not required. (Ville)
v7:
- Remove the call to drm_WARN_ON() when checking
intel_cmtg_disable_requires_modeset() and use a FIXME in the comment
instead.
- Remove the !HAS_CMTG() guard from intel_cmtg_get_config(), which is
static and its caller is already protected by that same condition.
- Also take the opportunity to put some Bspec references in the commit
trailers section.
v8:
- Use HAS_TRANSCODER() instead of intel_crtc_for_pipe(). (Ville)
- Ensure transcoder power well is enabled before reading
TRANS_DDI_FUNC_CTL2. (Ville)
