[Intel-gfx] [PATCH 1/2] drm/i915/dmabuf: fix broken build

2021-10-21 Thread Matthew Auld
wbinvd_on_all_cpus() is only defined on x86 it seems, plus we need to
include asm/smp.h here.

Jani, would it make sense to cherry-pick this to -fixes? The offending
commit is in drm-next, and there have been a few reports around this.

Fixes: a035154da45d ("drm/i915/dmabuf: add paranoid flush-on-acquire")

If the Fixes: tag is in place, our tooling will cherry-pick it where it
belongs. (In this case, drm-intel-next-fixes, not drm-intel-fixes.)

Cc: Rodrigo who covers drm-intel-next-fixes atm.

BR,

PS. 'dim tc a035154da45d' tells you where that commit is:

drm/drm-next
drm-intel/drm-intel-gt-next
drm-misc/drm-misc-next
drm-misc/topic/amdgpu-dp2.0-mst

So we see it's not in Linus' tree.

Yeah, I forgot to add the fixes tag here unfortunately.

Already merged? What's the commit id to be cherry-picked? Rodrigo can do
it manually.

Note to self, we should set up some way to check which maintainer is
responsible for which branches and when.

not sure I understand why this is a fix. Sure, it's true, but right now
this file can't be built on any other arch.

For clflush, wbind, etc, I'd rather change the code to use things from
drm_cache rather than ifdef it out locally. This is
"Reported-by: kernel test robot ", but what's the error?

I guess it depends on the kernel config, but it reported:
error: implicit declaration of function 'wbinvd_on_all_cpus'

AFAIK it's the missing , the CONFIG_X86 thing is just for
good measure.

I didn't spot anything in drm_cache which just offers a simple wrapper
for wbinvd?

not sure I understand why this is a fix. Sure, it's true, but right now
this file can't be built on any other arch.

For clflush, wbind, etc, I'd rather change the code to use things from
drm_cache rather than ifdef it out locally. This is
"Reported-by: kernel test robot ", but what's the error?


I guess it depends on the kernel config, but it reported:
error: implicit declaration of function 'wbinvd_on_all_cpus'


oh, ok. The commit message was not very clear. Just checked and this also 
matches what is done
in gem/i915_gem_pm.c  (although gt/intel_ggtt.c just includes it
unconditionally)



AFAIK it's the missing , the CONFIG_X86 thing is just for
good measure.

I didn't spot anything in drm_cache which just offers a simple wrapper
for wbinvd?


there isn't yet, but it's something we are adding as we add suppport for
other archs.

thanks

Jani, would it make sense to cherry-pick this to -fixes? The
offending
commit is in drm-next, and there have been a few reports
around this.

Fixes: a035154da45d ("drm/i915/dmabuf: add paranoid flush-on-

If the Fixes: tag is in place, our tooling will cherry-pick it
where it
belongs. (In this case, drm-intel-next-fixes, not drm-intel-

Yeah, I forgot to add the fixes tag here unfortunately.


Already merged? What's the commit id to be cherry-picked? Rodrigo
can do
it manually.


Yeah, it was merged to gt-next:

777226dac058 ("drm/i915/dmabuf: fix broken build")


picked up to drm-intel-next-fixes


Thanks.



thanks,

Note to self, we should set up some way to check which maintainer
is
responsible for which branches and when.

Yeah, it was merged to gt-next:

picked up to drm-intel-next-fixes


Thanks.


Hmm it looks like we have this in -fixes (and in -gt) while Linus has 
explicitly thrown it out (see 
https://lists.freedesktop.org/archives/dri-devel/2021-November/330928.html). 



End result is that now we have a different Kernel Test Robot warning 
("asm/smp.h is included more than once.").


So we need to fish out "drm/i915/dmabuf: fix broken build" out from 
fixes with a revert or what?

Tvrtko
