[Mesa-dev] [PATCH V3] i965 : Optimize atom state flag checks

[aravindan . muthukumar]

From: Aravindan Muthukumar 

This patch improves CPI Rate(Cycles per Instruction) and branch miss predict
for i965. The function check_state() was showing CPI retired rate.

Performance stats with android:
- CPI retired lowered by 28% (lower is better)
- Branch missprediction lowered by 13% (lower is better)
- 3DMark improved by 2%

The dissassembly doesn't show difference, although above results were observed
with patch.

V2:
- Removed memset() change
- Changed commit message as per review comments

V3:
- Indentation and changes to remove check_state as function

[Mesa-dev] [PATCH 2/2] glsl: rework misleading block layout code

[Timothy Arceri]

From the ARB_uniform_buffer_object spec:

   ""shared" uniform blocks, the default layout, ..."

This doesn't fix anything as the default layout is already applied
at this point but fixes the misleading code/comment.

A perf_warn here seems reasonable though it makes more sense to me to make

One thing to keep in mind: the max MOCS version can vary by platform (hopefully
it doesn't).

Why are we stomping device->mocs_version to MOCS_TABLE_VERSION?  Are you
just trying to avoid the version 0?  If so, why not just have

/* If the MOCS_TABLE_VERSION query fails, assume version 1 */
if (device->mocs_version == 0)
  device->mocs_version = 1;



I think the switch looks better, especially as the versions increase.


I don't think we want to have it dependent on a #define in an external
header file.  What if someone updates it for i965 and doesn't update anv or
vice-versa?




Yeah, I am removing that external define as mentioned in the other thread. I
think it was a bad idea that I jammed in at the last minute.

I think you forgot to rename this function too. (dri2_surface_set_out_fence).

Hmm, if we set it here, we would end up with the ->destroy_surface()
callback seeing -1 as the fence FD. For Android that would mean that
cancel_buffer() is called without a fence.

What I had in my mind was adding a dri2_surf_destroy() function that
would be called by platform backends before freeing the surf struct
(analogically to dri2_surf_init() after allocating the struct).

> return dri2_dpy->vtbl->destroy_surface(drv, dpy, surf);
>  }

Other than the above, I think this looks reasonably.

However, depending on how costly inserting a fence is (I think it
might mean flushing a command buffer on some platforms) we might need
a mechanism for the platform backend to opt-in for fences, i.e. tell
the dri2 core code that it's interested in them, rather than
requesting them by default. I'd like to hear more opinions on this,
though.

Best regards,
Tomasz

[Mesa-dev] [EGL android: accquire fence implementation 2/2] i965: Queue the buffer with a sync fence for Android OS v4.1

[Zhongmin Wu]

Before we queued the buffer with a invalid fence (-1), it will
make some benchmarks failed to test such as flatland.

Now we get the out fence during the flushing buffer and then pass
it to SurfaceFlinger in eglSwapbuffer function.

v2: a) Also implement the fence in cancelBuffer.
b) The last sync fence is stored in drawable object
   rather than brw context.
c) format clear.

v3: a) Save the last fence fd in DRI Context object.
b) Return the last fence if the batch buffer is empty and
   nothing to be flushed when _intel_batchbuffer_flush_fence
c) Add the new interface in vbtl to set the retrieve fence

v3.1 a) close fd in the new vbtl interface on none Android platform

v4: a) The last fence is saved in brw context.
b) The retrieve fd is for all the platform but not just Android
c) Add a uniform dri2 interface to initialize the surface.

v4.1: a) make some changes of variable name.
  b) the patch is breaked into two patches.

Always save the last fence in the brw context when flushing
buffer. If the buffer is nothing to be flushed, then return
the last fence when asked for.

[Mesa-dev] [EGL android: accquire fence implementation 1/2] i965: Return the last fence if the batch buffer is empty and nothing to be flushed when _intel_batchbuffer_flush_fence.

[Zhongmin Wu]

Always save the last fence in the brw context when flushing
buffer. If the buffer is nothing to be flushed, then return
the last fence when asked for.

For lower overhead in the CS ioctl.
Winsys allocators are not used with interprocess-sharable
resources.

Hi Marek,

Could I know from how your this way reduces overhead in CS
ioctl? reusing BO to short bo list?


The kernel part of the work hasn't been done yet. The idea is
that nonsharable buffers don't have to be revalidated by TTM,

OK, Maybe I only can see the whole picture of this idea when you
complete kernel part.
Out of curious,  why/how can nonsharable buffers be revalidated by
TTM without exposing like amdgpu_bo_make_resident api?


I think the idea is that all nonsharable buffers will be backed by the 
same reservation object, so TTM can skip buffer validation if no 
buffer has been moved. It's just an optimization for the current design.



With mentioned in another thread, if we can expose make_resident
api, we can remove bo_list, even we can remove reservation
operation in CS ioctl.
And now, I think our bo list is a very bad design,
first, umd must create bo list for every command submission, this
is a extra cpu overhead compared with traditional way.
second, kernel also have to iterate the list, when bo list is too
long, like OpenCL program, they always throw several thousands BOs
to bo list, reservation must keep these thousands ww_mutex safe,
CPU overhead is too big.

So I strongly suggest we should expose make_resident api to user
space. if cannot, I want to know any specific reason to see if we
can solve it.


Yeah, I think the BO list idea is likely to die sooner or later. It 
made sense for GL before bindless was a thing. Nowadays I don't see 
much value in it.


MesaGL will keep tracking the BO list because it's a requirement for 
good GL performance (it determines whether to flush IBs before BO 
synchronization, it allows tracking fences for each BO, which are used 
to determine dependencies between IBs, and that all allows async SDMA 
and async compute for GL, which doesn't have separate queues).


However, we don't need any BO list at the libdrm level and lower. I 
think a BO_CREATE flag that causes that the buffer is added to a 
kernel-side per-fd BO list would be sufficient. How the kernel manages 
its BO list should be its own implementation detail. Initially we can 
just move the current BO list management into the kernel.
I guess this idea will make bo list worse, which just decrease umd 
effort, but increase kernel driver complication.


First, from your and Christian's comments, we can get this agreement 
that bo list design is not a good way.

My proposal of exposing amdgpu_bo_make_resident is to replace bo list.
If we can make all needed bo resident, then we don't need to validate it 
again in cs ioctl, then we don't need their reservation lock more. After 
job pushed to scheduler, then we can un-resident BOs.
Even we can make it for VM bo, then we don't need to check vm update 
again while done in va map ioctl.


If this is got done(eviction has been improved more), I cannot see any 
obvious gap for performance.


What do you think of this proposal of exposing amdgpu_bo_make_resident 
api to user space? Or any other idea we can discuss.


If you all agree with, I can volunteer to try with UMD guys.

Regards,
David Zhou



Marek





Regards,
David Zhou


so it should remove a lot of kernel overhead and the BO list
remains the same.

Marek



Thanks,
David Zhou


v2: It shouldn't crash anymore, but the kernel will
reject the new flag.

[Mesa-dev] [PATCH 3/3] radv: initial support for shared semaphores

[Dave Airlie]

From: Dave Airlie 

This adds support for sharing semaphores using kernel syncobjects.

Syncobj backed semaphores are used for any semaphore which is
created with external flags, and when a semaphore is imported,
otherwise we use the current non-kernel semaphores.

Temporary imports from syncobj fd are also available, these
just override the current user until the next wait, when the
temp syncobj is dropped.

[Mesa-dev] radv shared semaphores (v2)

[Dave Airlie]

Indeed. Thanks.

Needs to be s/instr/intrin/, but yeah, good catch :)

Re: [Mesa-dev] [PATCH] st/mesa: add destroy_drawable interface

[Brian Paul]

Looks good to me, but you might want to wait a day to see if there's any 
additional review feedback.

With this patch, the st manager will maintain a hash table for
the active framebuffer interface objects. A destroy_drawable interface
is added to allow the state tracker to notify the st manager to remove
the associated framebuffer interface object from the hash table,
so the associated framebuffer and its resources can be deleted
at framebuffers purge time.

Fixes bug 101829 "read-after-free in st_framebuffer_validate"

Ran into trouble with this because of the deduplication we do for
batch->exec_bos[]. It kept insisting that I had added the batch first...

Doing a swap of first/last validation entry looks more pleasant than the
various hacks I have to skip the deduplication, or add a special case
add_batch_bo().

Re: [Mesa-dev] [PATCH V2] i965 : Optimize atom state flag checks

[Lionel Landwerlin]

Just some style comments, feel free to ignore them.

From: Aravindan Muthukumar 

This patch improves CPI Rate(Cycles per Instruction)
and branch mispredict for i965. The function check_state()
was showing CPI retired rate.

Performance stats with android:
CPI retired lowered by 28% (lower is better)
Branch missprediction lowered by 13% (lower is better)
3DMark improved by 2%

The dissassembly doesn't show difference, although above
results were observed with patch.

You might want to re-indent this.
Also maybe that function can be rename since it won't check anything

Why not replacing the last call to check_state() by CHECK_BRW_STATE()

Instead of adding -lstdc++ to LIBADD, you want to use the C++ linker
by specifying a dummy cpp file in EXTRA_*_SOURCES. grep for dummy.cpp
and you'll fine examples.

No.  You don't add someone's R-b unless they actually say "Reviewed-by".
 Various people still have issues with the content of this change.

[Mesa-dev] [PATCH V3] i965 : Optimize atom state flag checks

[Yogesh Marathe]

From: Aravindan Muthukumar 

This patch improves CPI Rate(Cycles per Instruction) and branch miss 
predict for i965. The function check_state() was showing CPI retired
rate.

Performance stats with android:
- CPI retired lowered by 28% (lower is better)
- Branch missprediction lowered by 13% (lower is better)
- 3DMark improved by 2%

The dissassembly doesn't show difference, although above results were
observed with patch.

V2:
- Removed memset() change
- Changed commit message as per review comments

V3:
- Indentation in check_and_emit_atom and commit msg corrected

2% to be exact, other stats are also present in commit message, the benchmark
was run at least 5 times before concluding and more than that during 
experimenting.

All of the benchmarks have variation in framerate.  In order to get
trustworthy data, you have to run the benchmark multiple times,
alternating "before" and "after," and perform statistical analysis on
the results.  Generally Student's t is used.  See
http://anholt.net/compare-perf/ for more details.

You should perform similar analysis on the CPU metric.  Other activity
in the system can affect these files.

[Mesa-dev] [PATCH] i965: Push no_hw down to the execbuf call

[Chris Wilson]

For the common path where we want to execute the batch, if we push the
no_hw detection down to the execbuf we can eliminate one loop over all
the execobjects. For the less common path where we don't want to execute
the batch, no_hw was leaving out_fence uninitialised.

To simplify later changes, the execbuf routine was then inlined into its
only caller.

How much variance do these metrics have? (particularly the overall score
of the benchmark)  How many times did you run the benchmark?

I'm inclined to keep them separate as well.

No its not statistical noise. As commit msg mentions, we used metrics CPI 
retired rate,
utilization, branch miss predict as metrics, these can be measured using SEP on 
IA.
It essentially enables event based sampling and we can measure these through 
counters.

When we did the analysis of tests we were running, we found 
brw_upload_pipeline_state->check_state functions having bad CPI rates and hence
we made changed there. The intention was always to reduce driver overhead, 
although
this is miniscule effort.

Sorry this is not something we have done, we tested on android functionality and
perf only. Performance benchmark 3dmark and overall stability of the android 
system 
were used as tests. Kindly let us know if you have specific tests to be run and 
we would
be happy to run that.

What CPU did you get the numbers on?

[Mesa-dev] [PATCH] st/mesa: add destroy_drawable interface

[Charmaine Lee]

With this patch, the st manager will maintain a hash table for
the active framebuffer interface objects. A destroy_drawable interface
is added to allow the state tracker to notify the st manager to remove
the associated framebuffer interface object from the hash table,
so the associated framebuffer and its resources can be deleted
at framebuffers purge time.

Fixes bug 101829 "read-after-free in st_framebuffer_validate"

[Mesa-dev] [Bug 101844] Artifacts in form of wrong pixels appearing on some surfaces

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=101844

--- Comment #7 from Fabian Maurer  ---
Sorry, look like I was wrong. There seem to always have been artifacts, but
since a newer Minecraft version they're colorful instead of black, making them
way more noticeable.

"LIBGL_ALWAYS_SOFTWARE=1" reduces the artifacts massively, and
"GALLIUM_DRIVER=swr LIBGL_ALWAYS_SOFTWARE=1" removes them.

Now, since I can't do a regression test, is there another way I could help?

As you've seen, I think there's some merit to a distinct name so we
don't get confused with exec_bos, I've settled for

  struct drm_i915_gem_exec_object2 *entry = &batch->validation_list[index];

as that fits into 80cols :)

Hi Marek,

Could I know from how your this way reduces overhead in CS
ioctl? reusing BO to short bo list?


The kernel part of the work hasn't been done yet. The idea is
that nonsharable buffers don't have to be revalidated by TTM,

OK, Maybe I only can see the whole picture of this idea when you
complete kernel part.
Out of curious,  why/how can nonsharable buffers be revalidated by
TTM without exposing like amdgpu_bo_make_resident api?


I think the idea is that all nonsharable buffers will be backed by the 
same reservation object, so TTM can skip buffer validation if no 
buffer has been moved. It's just an optimization for the current design.



With mentioned in another thread, if we can expose make_resident
api, we can remove bo_list, even we can remove reservation
operation in CS ioctl.



Actually that is NOT a resident api. E.g. in other words BOs marked as 
this are just swapped out like other BOs.


It's just that on command submission additionally to the BOs which come 
from the BO list we have the BOs associated to the process as well.



And now, I think our bo list is a very bad design,
first, umd must create bo list for every command submission, this
is a extra cpu overhead compared with traditional way.
second, kernel also have to iterate the list, when bo list is too
long, like OpenCL program, they always throw several thousands BOs
to bo list, reservation must keep these thousands ww_mutex safe,
CPU overhead is too big.

So I strongly suggest we should expose make_resident api to user
space. if cannot, I want to know any specific reason to see if we
can solve it.


Yeah, I think the BO list idea is likely to die sooner or later. It 
made sense for GL before bindless was a thing. Nowadays I don't see 
much value in it.


Completely agree. The BO list API was not a good idea in the first place.

Regards,
Christian.



MesaGL will keep tracking the BO list because it's a requirement for 
good GL performance (it determines whether to flush IBs before BO 
synchronization, it allows tracking fences for each BO, which are used 
to determine dependencies between IBs, and that all allows async SDMA 
and async compute for GL, which doesn't have separate queues).


However, we don't need any BO list at the libdrm level and lower. I 
think a BO_CREATE flag that causes that the buffer is added to a 
kernel-side per-fd BO list would be sufficient. How the kernel manages 
its BO list should be its own implementation detail. Initially we can 
just move the current BO list management into the kernel.

David Zhou


so it should remove a lot of kernel overhead and the BO list
remains the same.

Marek



Thanks,
David Zhou


v2: It shouldn't crash anymore, but the kernel will
reject the new flag.

[Mesa-dev] [Bug 101843] Latest mesa git fails to compile in mesa/main/marshal.c

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=101843

--- Comment #4 from Fabian Maurer  ---
Well, now that I set it up again, it suddenly works. Maybe a configuration
problem, but I really can't see what I changed.
Thank you for testing, is there an option to resolve this as WORKSFORME?

How did you determine that your results are not just statistical noise?
Did you do some sort of significance testing?  Which test, significance
level and sample size did you use?  What CPU did you get the numbers on?

Thank you.

[Mesa-dev] [PATCH] configure.ac: rework wayland-protocols handling

[Emil Velikov]

From: Emil Velikov 

At dist/distcheck time we need to ensure that all the files and their
respective dependencies are handled.

At the moment we'll bail out as the linux-dmabuf rules are guarded in a
conditional. Move them outside of it and drop the sources from
BUILT_SOURCES.

Thus the files will be generated only as needed, which will happen only
after the wayland-protocols dependency is enforced in configure.ac.

Hrm... I can, but I think the problem is most likely more general than
CCS_E.  The fact that CCS_E happens to show it off doesn't mean that's why
we need to do it.

Re: [Mesa-dev] [PATCH] dri: Make classic drivers allow __DRI_CTX_FLAG_NO_ERROR.

Grigori recently added EGL_KHR_create_context_no_error support,

driContextSetFlags() will already handle it properly for us, but the
classic drivers all have code to explicitly balk at unknown flags.  We
need to let it through or they'll fail to create a no_error context.


I'm almost afraid to ask... are there tests that try to create a
no_error context?



I have now posted a test to the piglit ML, which might be useful for 
testing this patch.

The NumSamples and FixedSampleLocation fields are set again later at

When we validate the texture sample count, pass the correct

Also add more comments about MSAA.

Oh :( Now I realize my comment about "we call the list validation_list"
must have made no sense.  Sorry about that.  I thought I called it that.

I'm not objecting too strongly, call it exec or exec_object if you like. 
The initializer use is pretty nice.

"validation list" is a bit of a weird name anyway...

Moved the HAVE_PLATFORM_WAYLAND guard after the BUILT_SOURCES and
checked the generated file.
Which seemingly is not enough... I have an idea - let's seen how well
it pans out.

[Mesa-dev] [PATCH] i965: Rename batch->exec_objects to validation_list

[Chris Wilson]

Within i965, we have many different objects and confusingly when
submitting an execbuf we have lists of both our internal objects and a
list of the kernel's drm_i915_gem_exec_object with very similar names.
Rename the kernel's validation list to avoid the collison as it is only
used for interfacing with the kernel and so a peripheral use of
"object".

To put a finer point on it, I'm fine with your patch landing as-is (go
ahead and add my R-B).  However, I am going to have to switch it over to
logical as part of my series since the MCS partial resolve code relies on
it being logical.

[Mesa-dev] [PATCH] svga: fix default case in svga_get_sample_position()

[Brian Paul]

If called for an unsupported number of samples, always return (.5, .5).
Fixes the Piglit arb_texture_multisample-fb-completeness test for
unsupported sample counts, such as 2.

Ideally, this function should not get called for unsupported sample
counts, but that'll be additional work...

This still leaves create_aux_state_map() using physical number of layers for
the actual allocation. I toyed a little with this hoping to put it in front my
i965-to-isl work. In the end it looks to me that moving away from physical
is easier/cleaner once the conversion to isl is done. This prevents us from
addressing both isl-based and native slice table-based leaving just the
isl-based. Moreover in case of slice table-based we would need to calculate
a layer-number divider as the slice table itself stores depth as physical.

There are altogether 6 places calling get_num_phys_layers() in the end.
I think these document nicely all the locations we need to consider. How does
this sound?


That's fine with me.

Hmm, how about

-   struct drm_i915_gem_exec_object2 *exec =
-  memset(&batch->exec_objects[batch->exec_count], 0, sizeof(*exec));
-   exec->handle = bo->gem_handle;
-   exec->alignment = bo->align;
-   exec->offset = bo->offset64;
-   exec->flags = bo->kflags;
+   batch->exec_objects[batch->exec_count] = (struct drm_i915_gem_exec_object2){
+  .handle = bo->gem_handle,
+  .alignment = bo->align,
+  .offset = bo->offset64,
+  .flags = bo->kflags,
+   };

and skip the impossible problem of naming?

But we still end up with a couple of 
struct drm_i915_gem_exec_object2 *
validation_entry = &batch->exec_objects[index];
Could I just call those exec_object?

Could I know from how your this way reduces overhead in CS ioctl? reusing
BO to short bo list?


The kernel part of the work hasn't been done yet. The idea is that
nonsharable buffers don't have to be revalidated by TTM,

OK, Maybe I only can see the whole picture of this idea when you complete
kernel part.
Out of curious,  why/how can nonsharable buffers be revalidated by TTM
without exposing like amdgpu_bo_make_resident api?


I think the idea is that all nonsharable buffers will be backed by the same
reservation object, so TTM can skip buffer validation if no buffer has been
moved. It's just an optimization for the current design.


With mentioned in another thread, if we can expose make_resident api, we
can remove bo_list, even we can remove reservation operation in CS ioctl.
And now, I think our bo list is a very bad design,
first, umd must create bo list for every command submission, this is a
extra cpu overhead compared with traditional way.
second, kernel also have to iterate the list, when bo list is too long,
like OpenCL program, they always throw several thousands BOs to bo list,
reservation must keep these thousands ww_mutex safe, CPU overhead is too
big.

So I strongly suggest we should expose make_resident api to user space. if
cannot, I want to know any specific reason to see if we can solve it.


Yeah, I think the BO list idea is likely to die sooner or later. It made
sense for GL before bindless was a thing. Nowadays I don't see much value
in it.

MesaGL will keep tracking the BO list because it's a requirement for good
GL performance (it determines whether to flush IBs before BO
synchronization, it allows tracking fences for each BO, which are used to
determine dependencies between IBs, and that all allows async SDMA and
async compute for GL, which doesn't have separate queues).

However, we don't need any BO list at the libdrm level and lower. I think a
BO_CREATE flag that causes that the buffer is added to a kernel-side per-fd
BO list would be sufficient. How the kernel manages its BO list should be
its own implementation detail. Initially we can just move the current BO
list management into the kernel.

Marek

David Zhou

so it should remove a lot of kernel overhead and the BO list remains the
same.

Marek



Thanks,
David Zhou

Mmmm ... the BUILT_SOURCES is in the same conditional in which the
linux-dmabuf-unstable-v1-protocol.c target is define so I don't think
that would be solving the problem and it doesn't seem to be doing so in
my travis:

The difference is that in the always use brw_emit_reloc patch end up
with 

@@ -661,18 +662,17 @@ brw_emit_buffer_surface_state(struct brw_context *brw,
   out_offset);

which was a bit too much of an eyesore for me.

Upon a second look - BUILT_SOURCES line is in a conditional which is

They're already in BUILT_SOURCES (line 78 in master), so I guess
something else is wrong.

[Mesa-dev] [PATCH V2] i965 : Optimize atom state flag checks

[aravindan . muthukumar]

From: Aravindan Muthukumar 

This patch improves CPI Rate(Cycles per Instruction)
and branch mispredict for i965. The function check_state()
was showing CPI retired rate.

Performance stats with android:
CPI retired lowered by 28% (lower is better)
Branch missprediction lowered by 13% (lower is better)
3DMark improved by 2%

The dissassembly doesn't show difference, although above
results were observed with patch.

For lower overhead in the CS ioctl.
Winsys allocators are not used with interprocess-sharable

Hi Marek,

Could I know from how your this way reduces overhead in CS ioctl?
reusing BO to short bo list?


The kernel part of the work hasn't been done yet. The idea is that 
nonsharable buffers don't have to be revalidated by TTM,
OK, Maybe I only can see the whole picture of this idea when you 
complete kernel part.
Out of curious,  why/how can nonsharable buffers be revalidated by TTM 
without exposing like amdgpu_bo_make_resident api?


With mentioned in another thread, if we can expose make_resident api, we 
can remove bo_list, even we can remove reservation operation in CS ioctl.

And now, I think our bo list is a very bad design,
first, umd must create bo list for every command submission, this is a 
extra cpu overhead compared with traditional way.
second, kernel also have to iterate the list, when bo list is too long, 
like OpenCL program, they always throw several thousands BOs to bo list, 
reservation must keep these thousands ww_mutex safe, CPU overhead is too 
big.


So I strongly suggest we should expose make_resident api to user space. 
if cannot, I want to know any specific reason to see if we can solve it.


Introducing a make_resident API will also help ARB_bindless_texture a 
lot, because currently when a texture is marked as resident, we have to 
re-validate the related buffers for every new CS, like traditional 
buffers. With a resident BO list the whole mechanism could be skipped.





Regards,
David Zhou
so it should remove a lot of kernel overhead and the BO list remains 
the same.


Marek



Thanks,
David Zhou


v2: It shouldn't crash anymore, but the kernel will reject the
new flag.

Sorry. I meant $(LOCAL_PATH) instead of $(COMPILER_PATH).
(copied wrong lines)

I've submitted a real patch for it.

[Mesa-dev] [PATCH] Android: fix spirv_info.c generation

[Chih-Wei Huang]

It's incorrect to use $(LOCAL_PATH) in makefile recipes since it's
changing. The typical way to handle it is to use private variable.
Fortunately in this case we can just simplify them to $^.

See further:
https://patchwork.freedesktop.org/patch/167718/

Also simplify LOCAL_GENERATED_SOURCES.

OK. I see the real problem.
The rules to build spirv_info.c are incorrectly
to use $(LOCAL_PATH).
Basically speaking, $(LOCAL_PATH) can't be used
in the recipes[1] since it is always changing.
When the recipe rules are executed its value
is not you expected.
(using it in targets and prerequisites is OK)

The typical way to handle it is to use private variable:

$(intermediates)/spirv/spirv_info.c: PRIVATE_LOCAL_PATH := $(LOCAL_PATH)

Then use PRIVATE_LOCAL_PAT

[Mesa-dev] [PATCH 05/10] mesa: inline remove_array_object()

[Samuel Pitoiset]

No need to check if ID is not 0 because _mesa_lookup_vao()
already prevents this to happen.
