git://anongit.freedesktop.org/drm/drm-intel into drm-next
UAPI Changes:
- drm/i915: Implement fdinfo memory stats printing
Use the newly added drm_print_memory_stats helper to show memory
utilisation of our objects in drm/driver specific fdinfo output.
To collect the stats we walk the per memory regions object lists
and accumulate object size into the respective drm_memory_stats
categories.
Cross-subsystem Changes:
- Backmerge of drm-next (to bring drm-intel-next for PXP changes)
Driver Changes:
- Wa_18028616096 now applies to all DG2 (Matt R)
- Drop Wa_22014600077 on all DG2 (Matt R)
- Add new ATS-M device ID (Haridhar)
- More Meteorlake (MTL) workarounds (Matt R, Dnyaneshwar, Jonathan,
Gustavo, Radhakrishna)
- PMU WARN_ON cleanup on driver unbind (Umesh)
- Limit GGTT WC flushing workaround to pre BXT/ICL platforms
- Complement implementation for Wa_16018031267 / Wa_16018063123

Beside reusing existing code, the main advantage of ref_tracker is
tracking per instance of wakeref. It allows also to catch double
put.
On the other side we lose information about the first acquire and
the last release, but the advantages outweigh it.

We had already grabbed the rpm wakeref at obj destruction path,
but it also required to grab the wakeref when object moves.
When i915_gem_object_release_mmap_offset() gets called by
i915_ttm_move_notify(), it will release the mmap offset without
grabbing the wakeref. We want to avoid that therefore,
grab the wakeref at i915_ttm_unmap_virtual() accordingly.
While doing that also changed the lmem_userfault_lock from
mutex to spinlock, as spinlock widely used for list.
Also changed if (obj->userfault_count) to
GEM_BUG_ON(!obj->userfault_count).

commit c50df701d49e ("drm/i915: Enable rpm wakeref tracking
whether runtime pm is enabled or not") enabled wakeref tracking
even for the mock device. Turns out that has somewhat significant
overhead, and on the glacial Core m3's we have in CI the vma
selftests are now exceeding the allotted time budget.
So let's disable the wakeref tracking once again for the mock
device in order to avoid blowing up the selftest runtime.

To optimize some task deferring it until runtime resume unless someone
holds a runtime PM reference (because in this case the task can be done
w/o the overhead of runtime resume), we have to use the runtime PM
get-if-active logic: If the runtime PM usage count is 0 (and so
get-if-in-use would return false) the runtime suspend handler is not
necessarily called yet (it could be just pending), so the device is not
necessarily powered down, and so the runtime resume handler is not
guaranteed to be called.
The fence revocation depends on the above deferral, so add a
get-if-active helper and use it during fence revocation.

Replace mixed "_fini"/"_cleanup"/"_cleanup_hw" suffixes found in names
of functions called from i915_driver_release() with "_release" suffix
consistently. This provides better code readability, especially
helpful when trying to work out which phase the code is in.
Functions names starting with "i915_driver_", i.e., those defined in
drivers/gpu/dri/i915/i915_drv.c, just have their "cleanup" or "fini"
parts of their names replaced with the "_release" suffix, while names
of functions coming from other source files have been suffixed with
"_driver_release" to avoid ambiguity with other possible .release entry
points.

Keep all the device-level PM management in intel_runtime_pm.h/c and move
all the display specific bits into their own file. Also add the new
header to Makefile.header-test.
Apart from the giant code move, the only difference is with the
intel_runtime_<get/put>_raw() functions, which are now exposed in the
header. The _put() version is also not conditionally compiled anymore
since it is ok to always pass the wakeref taken from the _get() to
__intel_runtime_pm_put (it is -1 if tracking is disabled).

We don't need the AUX power for the whole duration of the detect, only
when we're doing AUX transfers. The AUX transfer function takes its own
reference on the AUX power domain already. The two places during detect
which access display core registers (not specific to a
pipe/port/transcoder) only need the power domain that is required for
that access. That power domain is equivalent to the device global power
domain on most platforms (enabled whenever we hold a runtime PM
reference) except on CHV/VLV where it's equivalent to the display power
well.
Add a new power domain that reflects the above, and use this at the two
spots accessing registers. With that we can avoid taking the AUX
reference for the whole duration of the detect function.
Put the domains asynchronously to avoid the unneeded on-off-on toggling.
Also adapt the idea from with_intel_runtime_pm et al. for making it easy
to write short sequences where a display power ref is needed.

By disabling a power domain asynchronously we can restrict holding a
reference on that power domain to the actual code sequence that
requires the power to be on for the HW access it's doing, by also
avoiding unneeded on-off-on togglings of the power domain (since the
disabling happens with a delay).
One benefit is potential power saving due to the following two reasons:
1. The fact that we will now be holding the reference only for the
necessary duration by the end of the patchset. While simply not
delaying the disabling has the same benefit, it has the problem that
frequent on-off-on power switching has its own power cost (see the 2.
point below) and the debug trace for power well on/off events will
cause a lot of dmesg spam (see details about this further below).
2. Avoiding the power cost of freuqent on-off-on power switching. This
requires us to find the optimal disabling delay based on the measured
power cost of on->off and off->on switching of each power well vs.
the power of keeping the given power well on.
In this patchset I'm not providing this optimal delay for two
reasons:
a) I don't have the means yet to perform the measurement (with high
enough signal-to-noise ratio, or with the help of an energy
counter that takes switching into account). I'm currently looking
for a way to measure this.
b) Before reducing the disabling delay we need an alternative way for
debug tracing powerwell on/off events. Simply avoiding/throttling
the debug messages is not a solution, see further below.
Note that even in the case where we can't measure any considerable
power cost of frequent on-off switching of powerwells, it still would
make sense to do the disabling asynchronously (with 0 delay) to avoid
blocking on the disabling. On VLV I measured this disabling time
overhead to be 1ms on average with a worst case of 4ms.
In the case of the AUX power domains on ICL we would also need to keep
the sequence where we hold the power reference short, the way it would
be by the end of this patchset where we hold it only for the actual AUX
transfer. Anything else would make the locking we need for ICL TypeC
ports (whenever we hold a reference on any AUX power domain) rather
problematic, adding for instance unnecessary lockdep dependencies to
the required TypeC port lock.
I chose the disabling delay to be 100msec for now to avoid the unneeded
toggling (and so not to introduce dmesg spamming) in the DP MST sideband
signaling code. We could optimize this delay later, once we have the
means to measure the switching power cost (see above).
Note that simply removing/throttling the debug tracing for power well
on/off events is not a solution. We need to know the exact spots of
these events and cannot rely only on incorrect register accesses caught
(due to not holding a wakeref at the time of access). Incorrect
powerwell enabling/disabling could lead to other problems, for instance
we need to keep certain powerwells enabled for the duration of modesets
and AUX transfers.
v2:
- Clarify the commit log parts about power cost measurement and the
problem of simply removing/throttling debug tracing. (Chris)
- Optimize out local wakeref vars at intel_runtime_pm_put_raw() and
intel_display_power_put_async() call sites if
CONFIG_DRM_I915_DEBUG_RUNTIME_PM=n. (Chris)
- Rebased on v2 of the wakeref w/o power-on guarantee patch.
- Add missing docbook headers.
v3:
- Checkpatch spelling/missing-empty-line fix.
v4:
- Fix unintended local wakeref var optimization when using
call-arguments with side-effects, by using inline funcs instead of
macros. In this patch in particular this will fix the
intel_display_power_grab_async_put_ref()->intel_runtime_pm_put_raw()
call).
No size change in practice (would be the same disregarding the
corresponding change in intel_display_power_grab_async_put_ref()):

Kudos to Stan for reporting the raw-wakeref WARNs this issue caused. His

after v1, and we are also not testing this config in CI.

It used to be handy that we only had a couple of headers, but over time
intel_drv.h has become unwieldy. Extract declarations to a separate
header file corresponding to the implementation module, clarifying the
modularity of the driver.
Ensure the new header is self-contained, and do so with minimal further
includes, using forward declarations as needed. Include the new header
only where needed, and sort the modified include directives while at it
and as needed.
No functional changes.
