[Intel-gfx] [PATCH v3 0/3] Move #define wbvind_on_all_cpus

[Intel-gfx] [PATCH v3 0/3] Move #define wbvind_on_all_cpus

[Michael Cheng]

This series moves the logic for wbvind_on_all_cpus to drm_cache. The logic
changes a little here, if platform is not x86 then we throw out a warning
for when wbvind_on_all_cpus is being called.

v2(Michael Cheng): Move and redo logic for wbvind_on_all_cpus. Also
		   add drm_cache.h where the function is being called and
		   remove uneeded header files.

v3(Michael Cheng): Updated commit messages.

Michael Cheng (3):
  drm_cache: Add logic for wbvind_on_all_cpus
  drm/i915/gem: Remove logic for wbinvd_on_all_cpus
  drm/i915/: Add drm_cache.h

[Intel-gfx] [PATCH v3 1/3] drm_cache: Add logic for wbvind_on_all_cpus

[Michael Cheng]

Add logic for wbvind_on_all_cpus for non-x86 platforms.

v2(Michael Cheng): Change logic to if platform is not x86, then
		   we add pr_warn for calling wbvind_on_all_cpus.

[Intel-gfx] [PATCH v3 2/3] drm/i915/gem: Remove logic for wbinvd_on_all_cpus

[Michael Cheng]

This patch removes logic for wbinvd_on_all_cpus and brings in
drm_cache.h. This header has the logic that outputs a warning
when wbinvd_on_all_cpus when its being used on a non-x86 platform.

Linus has been pretty clear that he won't accept patches that add macros 
that works on one arch and warns on others anymore in i915 and I figure 
even less so in drm code.

So we shouldn't try to move this out to drm. Instead we should restrict 
the wbinvd() inside our driver to integrated and X86 only. For discrete 
on all architectures we should be coherent and hence not be needing 
wbinvd().

Thanks,

/Thomas

the warn is there to guarantee we don't forget a code path. However
simply adding the warning is the real issue: we should rather guarantee
we can't take that code path. I.e., as you said refactor the code to
guarantee it works on discrete without that logic.

	$ git grep wbinvd_on_all_cpus -- drivers/gpu/drm/
	drivers/gpu/drm/drm_cache.c:    if (wbinvd_on_all_cpus())
	drivers/gpu/drm/drm_cache.c:    if (wbinvd_on_all_cpus())
	drivers/gpu/drm/drm_cache.c:    if (wbinvd_on_all_cpus())

	drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c:      * Currently we just do a heavy handed wbinvd_on_all_cpus() here since
	drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c:             wbinvd_on_all_cpus();

It looks like we actually go through this on other discrete graphics. Is
this missing an update like s/IS_DG1/IS_DGFX/? Or should we be doing
something else?

	drivers/gpu/drm/i915/gem/i915_gem_pm.c:#define wbinvd_on_all_cpus() \
	drivers/gpu/drm/i915/gem/i915_gem_pm.c:         wbinvd_on_all_cpus();

Those are for suspend. Revert ac05a22cd07a ("drm/i915/gem: Almagamate clflushes on suspend")
or extract that part to a helper function and implement it differently
for arches != x86?

	drivers/gpu/drm/i915/gem/i915_gem_pm.c: wbinvd_on_all_cpus();

Probably take a similar approach to the suspend case?

	drivers/gpu/drm/i915/gt/intel_ggtt.c:           wbinvd_on_all_cpus();

This one comes from 64b95df91f44 ("drm/i915: Assume exclusive access to objects inside resume")
Shouldn't that be doing the invalidate if the write domain is I915_GEM_DOMAIN_CPU


In the end I think the warning would be ok if it was the cherry on top,
to guarantee we don't take those paths. We should probably have a
warn_once() to avoid spamming the console. But we  also have to rework
the code to guarantee we are the only ones who may eventually get that
warning, and not the end user.

For a helper function, I have a #define for all non x86 architecture 
that gives a warn on [1] within drm_cache.h Or would it be better to 
implement a helper function instead?

Could we first add the helper function/#define for now, and rework the 
code in a different patch series?

Re: [Intel-gfx] [PATCH v3 2/3] drm/i915/gem: Remove logic for wbinvd_on_all_cpus

[Thomas Hellström (Intel)]

Hi, Michael, others.

This is the response from Linus last time we copied that already 
pre-existing wbinvd_on_all_cpus() macro to another place in the driver:

https://lists.freedesktop.org/archives/dri-devel/2021-November/330928.html

My first interpretation of this is that even if there currently are 
similar patterns in drm_cache.c, we shouldn't introduce more, 
encouraging other drivers to use incoherent IO.

Other than that I think we should move whatever wbinvds we can over to 
the ranged versions, unless that is proven to be a performance drop.

Finally for any wbinvds left in our driver, ensure that they are never 
executed for any gpu where we provide full coherency. That is all 
discrete gpus (and to be discussed integrated gpus moving forward).

Might be that drm maintainers want to chime in here with other views.

Thanks,

Thomas

[Intel-gfx] [PATCH v3 3/3] drm/i915/: Add drm_cache.h

[Michael Cheng]

Add drm_cache.h to additionals files that calls wbinvd_on_all_cpus and
remove un-needed header files. This will prevent compile errors when
building for non-x86 platforms, as well as output a warning when
wbinvd_on_all_cpus is being called incorrectly.
