Which platform was the regression on? Broadwell has some weirdness if you
disable PPGTT which might cause PTE MOCS to fall back to UC. I think at least
aliasing PPGTT has been enabled since pretty early for Broadwell. If there is no
ppgtt overrides here, then I'm not sure what would be going on - it sound
sketchy to me too.

I haven't really followed any of the isl stuff, but it lgtm.

[Mesa-dev] [PATCH 2/3] i965/miptree: Set logical_depth0 == 6 for cube maps

[Jason Ekstrand]

This matches what we do for cube maps where logical_depth0 is in number of
face-layers rather than number of cubes.  This does mean that we will
temporarily be setting the surface bounds too loose for cube map textures
but we are already setting them too loose for cube arrays and we will be
fixing that in the next commit anyway.

In other words, the depth field for cube maps is in number of cubes not

[Mesa-dev] [PATCH 3b/3] i965: Stop muging cube array lengths by 6

[Jason Ekstrand]

From the Sky Lake PRM:

   "For SURFTYPE_CUBE: For Sampling Engine Surfaces and Typed Data Port
   Surfaces, the range of this field is [0,340], indicating the number of

In other words, the depth field for cube maps is in number of cubes not
number of 2-D slices so we need to divide by 6.  ISL will do this correctly
for us assuming that we provide it with the correct array bounds which it
expects to be in 2-D slices.  It appears as if we've been doing this wrong
ever since we first added cube map arrays for Sandy Bridge and the change
to ISL made things slightly worse.  While we're at it, we now need to remoe
the shader hacks we've always done since they were only needed because we
were setting the depth field six times too large.

[Mesa-dev] [PATCH 1/3] i965: Use intel_get_image_dims in alloc_texture_storage

[Jason Ekstrand]

The intel_get_image_dims helper function handles some image dimension
sanitization for us for things such as 1-D array textures.  We should
probably be using it here.

[Mesa-dev] [PATCH 0/3] i965: Correctly set RENDER_SURFACE_STATE::Depth for

[Jason Ekstrand]

From the Sky Lake PRM:

   "For SURFTYPE_CUBE: For Sampling Engine Surfaces and Typed Data Port
   Surfaces, the range of this field is [0,340], indicating the number of
   cube array elements (equal to the number of underlying 2D array elements
   divided by 6). For other surfaces, this field must be zero."

In other words, the depth field for cube maps is in number of cubes not
number of 2-D slices so we need to divide by 6.  It appears as if we've
been doing this wrong ever since we first added cube map arrays for Sandy
Bridge.  We've also had a shader hack to divide the size Z dimension of
cube maps by 6 in the textureSize call.  This is completely bogus and the
only reason for it is that we've been setting the depth six times too
large.

This little series fixes this.  In order to keep things back-portable,
patch 3 comes in two versions.  Version (a) is based on pre-ISL and should
be backportable to 12.0 or maybe even 11.2 or 11.1.  Version (b) on the
other hand is based on top of the ISL work and can be applied on master.

Re: [Mesa-dev] [PATCH 7/7] i965: Delete the FS_OPCODE_INTERPOLATE_AT_CENTROID virtual opcode.

I remember arguing about this when it got added -- tradeoff was payload
size/register pressure vs needing to call out to this unit, if centroid
barycentric coords weren't required for anything else? It does seem fairly
pointless, though.

Thanks a lot for testing!

It looks like somehow your driver (or gallium) is triggering a call to
DRI image loader getBuffers() callback with front buffer bit set in
the image mask, but window surfaces on Android provide only back
buffers.

My understanding of the semantics was that the callback should deny
such requests, so that's how I implemented it. However it isn't really
well documented, so potentially it should only provide buffers that
are available and ignore the rest without bailing out. Could someone
more familiar with this extension comment on this?

Hmm, I rebased them on Mesa master just before sending. Let me try to
create a sandbox branch in our chromium tree.

I've tested out patches 1-6 with virgl and I don't get anything
displayed. I get this message:

EGL-DRI2: Front buffer is not supported for window surfaces

That's as far as I investigated. I'll look into it some more tomorrow.

Patches 7-10 wouldn't apply. Do you have a git tree with the series?

 We are using our heavily rewritten fork of some old drm_gralloc
 release. It supports only render nodes and PRIME FDs and doesn't
 export the DRI device FD outside of its internals (which isn't
 actually even fully correct, at least for PRIME and render nodes, see
 my reply to Rob's comments).

Did you mean having the PRIME FD in native_handle_t::data[0]?

If so, it's more or less guaranteed by the API, because all file
descriptors in handle have to be stored in first N (equals to
native_handle_t::numFds) ints of native_handle_t::data[] for
respective general code to properly transfer the FDs through binder
when sharing between processes.

Our gralloc currently supports only one PRIME FD per buffer (no
separate memory planes for planar YUV) and stores it exactly in
native_handle_t::data[0].

 Existing code would fail with -1 as file descriptor, wouldn't it? Or
 I'm failing to see something?

Dylan suggested you use pip --user to install a newer version of Mako.
Is that a workable solution to your problem?

I'm having a hard time getting excited about making upstream support
building against 2011-era software, when doing so makes transitioning
to Python 3 harder (which is useful for forward-looking distros).
Especially when Debian stable and the last two Ubuntu LTS releases
(2016 and 2014) ship a recent enough version...it's just the LTS
three back (2012) that doesn't work...

[Mesa-dev] [PATCH] i965: Use tex_mocs instead of rb_mocs for GL images.

[Kenneth Graunke]

Fixes a 10-20% performance regression in OglCSDof caused by commit
5a8c89038abab0184ea72664ab390ec6ca58b4d6, which made images (in the
image load/store sense) use BDW_MOCS_PTE instead of BDW_MOCS_WB.

This seems sketchy, as the default PTE value is supposed to be
WB LLC eLLC, which is the same as our MOCS WB setting.  It's only
supposed to change when using a surface for display, which won't
ever happen for images.  Something may be wrong in the kernel...

[Mesa-dev] [PATCH 7/8] anv: Perform rasterizer discard in the SOL stage instead of the clipper.

[Kenneth Graunke]

See commit b0629e6894513a2c49a018bc3342a4e55435a236, where we discovered
that the SOL stage's "Rendering Disable" feature is a lot faster at
throwing away all geometry than the clipper's "reject all" mode.

[Mesa-dev] [PATCH 1/8] genxml: Add CLIPMODE_* prefix to 3DSTATE_CLIP's "Clip Mode" enum values.

[Kenneth Graunke]

Gen6-7.5 use CLIPMODE_REJECT_ALL, while Gen8+ just used REJECT_ALL.
Being consistent will let me unify code, and I prefer having the prefix.

[Mesa-dev] [PATCH 3/8] anv: Fix near plane clipping on Gen7/7.5.

[Kenneth Graunke]

The Gen7/7.5 clip code used APIMODE_OGL, while the Gen8+ clip code used
APIMODE_D3D.  The meaning hasn't changed, so one of these must be wrong.

It appears that the hardware documentation is completely wrong.  It
claims that the "API Mode" bit means:

   0hAPIMODE_OGLNEAR_VP boundary == 0.0 (NDC)
   1hAPIMODE_D3DNEAR_VP boundary == -1.0 (NDC)

However, DirectX typically uses 0.0 for the near plane, while unextended
OpenGL uses -1.0.  i965's gen6_clip_state.c uses APIMODE_D3D for the
GL_ZERO_TO_ONE case, so I believe the meanings are backwards from what
the documentation says.

Section 23.2 ("Primitive Clipping") of the Vulkan 1.0.21 specification
contains the following equations:

   -w_c <= x_c <= w_c
   -w_c <= y_c <= w_c
  0 <= z_c <= w_c

This means that Vulkan follows D3D semantics.

Hi Andy,

I just submitted another patch set, most of the issues you reported are solved, 
please see the information below:

- Giving different frame rate should result different output size. The final 
result from my side is very close to the CBR I set. Please give a try with 
different frame rate and bit rate.

- Picture corruption (half height pic) is caused by interlaced setting. 
Interlace encoding is not supported. However, for transcoding case, VAAPI 
decode will use interlace mode, which will cause this issue. The temp solution 
is to use an Environmental Variable to disable interlace when doing 
transcoding. Please try the following command with the new patch:
DISABLE_INTERLACE=true gst-launch-1.0 filesrc 
location=~/big_buck_bunny_720p_1mb.mp4 ! qtdemux ! h264parse ! vaapidecode ! 
vaapih264enc ! filesink location=out.264

- I420 yuv -> nv12 case seems working fine on my side, can you please provide 
the testing raw file and command you were using? I want to reproduce the issue 
from my side and try to fix it if possible. Thanks a lot!


Will try new patches tomorrow.

Here's a few frames of I420 in mkv at 1 fps, should play directly OK 
with mplayer/mpv - building is yellow.


https://drive.google.com/file/d/0BxP5-S1t9VEEc3RhNzBQclhlNWc/view?usp=sharing

Of course google will make a preview but you should be able to download 
the raw file by moving mouse towards the top of the screen.


Do

gst-launch-1.0 -f filesrc location=I420-5f.mkv ! matroskademux ! 
vaapih264enc ! h264parse ! mp4mux ! filesink location=out-I420-1.mp4


and the result is blue building, force gstreamer to convert to nv12 
result is OK.


gst-launch-1.0 -f filesrc location=~/I420-5f.mkv ! matroskademux ! 
videoconvert ! video/x-raw,format=NV12 ! vaapih264enc ! h264parse !

Re: [Mesa-dev] [RFC] gallium/u_queue: add barrier function

[Rob Clark]

possibly.. although sprinkling queue_barrier() calls (which is at
least useful for debugging, although I think I won't use it in the end
after debugging) hasn't found the issue yet.  I did at least find an
issue w/ fence handling (I was grabbing the fence # potentially before
the batch was flushed), but that also doesn't seem to be the issue I
am seeing.

The idea of having a ring of N fences (where N is given by
max_jobs-1), rather than embedding the fence in the refcnt'd batch, is
interesting, and sounds like it might solve some problems.  I may end
up doing that..

Re: [Mesa-dev] [RFC] gallium/u_queue: add barrier function

[Marek Olšák]

I think your issue is that you have self-releasing jobs with the
cleanup callback and you automatically lose fences that way, so there
is no way to wait for completion.

Since you have only 1 thread with N jobs at most, I suggest you keep
N+1 fences around (a ring of fences) that you reuse for new jobs and
keep a pointer to the most-recently-used fence. That way you know
which fence you need to wait on to make the whole queue idle.

[Mesa-dev] [Bug 96979] Mesa 10.5.7 implementation error: Trying to disable permanently enabled extensions

[bugzilla-daemon]

Actually the issue is that glxinfo hits a segfault later. I guess
glGetStringi() or GL_NUM_EXTENSIONS gets confused...

As I recall, at some point Brian explicitly added support for disabling
always-on exts. Not sure if that work was already in 10.5 or not... def worth
checking a more recent version of mesa -- 10.5 is long out of support.

Re: [Mesa-dev] [PATCH 06/11] vl/util: add copy func for yv12image to nv12surface

[Zhang, Boyuan]

Hi Andy,

I just submitted another patch set, most of the issues you reported are solved, 
please see the information below:

- Giving different frame rate should result different output size. The final 
result from my side is very close to the CBR I set. Please give a try with 
different frame rate and bit rate.

- Picture corruption (half height pic) is caused by interlaced setting. 
Interlace encoding is not supported. However, for transcoding case, VAAPI 
decode will use interlace mode, which will cause this issue. The temp solution 
is to use an Environmental Variable to disable interlace when doing 
transcoding. Please try the following command with the new patch:
DISABLE_INTERLACE=true gst-launch-1.0 filesrc 
location=~/big_buck_bunny_720p_1mb.mp4 ! qtdemux ! h264parse ! vaapidecode ! 
vaapih264enc ! filesink location=out.264

- I420 yuv -> nv12 case seems working fine on my side, can you please provide 
the testing raw file and command you were using? I want to reproduce the issue 
from my side and try to fix it if possible. Thanks a lot!


Hi Christian,

Besides fixing those issue listed above, I also modified the code based on your 
suggestions, e.g. adding mutex lock/unlock. Please take a look at the new patch 
set, and feel free to give any suggestions/comments. Thanks!

Regards,
Boyuan

I think we can keep the patches mostly as they are now, but I would like to get 
a bit more positive feedback from Andy and maybe others.

E.g. at least we should be able to encode something without crashing on Tonga 
and other hardware generations as well before we push it upstream.

Christian.

[Mesa-dev] [PATCH 1/2] nir: Add a base const_index to shared atomic intrinsics.

[Kenneth Graunke]

Commit 52e75dcb8c04c0dde989970c4c587cbe8313f7cf made nir_lower_io
start using nir_intrinsic_set_base instead of writing const_index[0]
directly.  However, those intrinsics apparently don't /have/ a base,
so this caused assert failures.

However, the old code was happily setting non-existent const_index
fields, so it was pretty bogus too.

Jason pointed out that load_shared and store_shared have a base,
and that the i965 driver uses that field.  So presumably atomics
should have one as well, so that loads/stores/atomics all refer
to variables with consistent addressing.

[Mesa-dev] [PATCH 10/12] st/va: add preset values for VAAPI encode

[Boyuan Zhang]

Add some hardcoded values hardware needs mainly for rate control purpose. With 
previously hardcoded values for OMX, the rate control result is not correct. 
This change fixed the rate control result by setting correct values for Vaapi.

[Mesa-dev] [PATCH 11/12] st/va: add environmental variable to disable interlace

[Boyuan Zhang]

Add environmental variable to disable interlace mode. At VAAPI decoding stage, 
driver can not distinguish b/w pure decoding case and transcoding case. And 
since interlace encoding is not supported, we have to disable interlace for 
transcoding case. The temporary solution is to use enviromental variable to 
disable interlace mode.

[Mesa-dev] [PATCH 08/12] st/va: get rate control method from configattrib

[Boyuan Zhang]

Rate control method is passed from app to driver through config attrib list. 
That is why we need to store this rate control method to config. And later on, 
we will pass this value to context->desc.h264enc.rate_ctrl.rate_ctrl_method.

Add function to copy from yv12 image to nv12 surface for VAAPI putimage call.

For putimage call, if image format is yv12 (or IYUV with U V field swap) and 
surface format is nv12, then we need to convert yv12 to nv12 and then copy the 
converted data from image to surface. We can't use the existing logic where 
surface is destroyed and re-created with yv12 format.

[Mesa-dev] [PATCH 05/12] st/va: add encode entrypoint

[Boyuan Zhang]

VAAPI passes PIPE_VIDEO_ENTRYPOINT_ENCODE as entry point for encoding case. We 
will save this encode entry point in config. config_id was used as profile 
previously. Now, config has both profile and entrypoint field, and config_id is 
used to get the config object. Later on, we pass this entrypoint to 
context->templat.entrypoint instead of always hardcoded to 
PIPE_VIDEO_ENTRYPOINT_BITSTREAM for decoding case previously.

[Mesa-dev] [PATCH 02/12] vl: add entry point

[Boyuan Zhang]

Add entrypoint to distinguish H.264 decode and encode. For example, in patch 
5/11 when is calling "VaCreateContext", "pps" and "sps" shouldn't be allocated 
for H.264 encoding. So we need to use the entry_point to determine this is 
H.264 decode or H.264 encode. We can use config to determine the entrypoint 
since config_id is passed to us for VaCreateContext call. However, for 
VaDestoyContext call, only context_id is passed to us. So we need to know the 
entrypoint in order to not free the pps/sps for encoding case.

[Mesa-dev] [Bug 96979] Mesa 10.5.7 implementation error: Trying to disable permanently enabled extensions

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=96979

--- Comment #2 from Kenneth Graunke  ---
This isn't something we want to support.

We should probably use fprintf rather than _mesa_problem so it doesn't print
"Mesa:  implementation error" as it isn't an implementation issue -
it's a warning to the user that the debug options they requested won't take
effect because it's unsupported.

I think you just want 0 here, always.


I thought too, but this will hit the assert at nvc0_tex.c:134 for image

worked fine. (Didn't until I properly fixed the various items.)

Re: [Mesa-dev] [PATCH] nvc0: add support for BGRA8 images

[Samuel Pitoiset]

Works fine on Fermi, but still need to test on Kepler1.

On 07/16/2016 09:09 PM, Ilia Mirkin wrote:

This is useful for pbo downloads, which are now accelerated with images.
BGRA8 is a moderately common format to do that in.

This needs testing on SM20 and SM30. I've tested it on SM35 and

bin/pbo-readpixels-small -auto

worked fine. (Didn't until I properly fixed the various items.)

Re: [Mesa-dev] [PATCH v3] glsl: reuse main extension table to appropriately restrict extensions

[Ilia Mirkin]

Well, I have a basic review on this from Eric Engestrom, who is not a
mesa expert (yet?) but has been giving out a lot of good review
comments lately, and nobody else has piped up saying they hate this,
so I'm going to push this in the next few days unless I hear any
objections. IMHO this is a nice simplification of the glsl parser
boilerplate, and removes the oft-forgotten glcpp annoyance.

This was added in commit 6f613abc2b, which looks really sketchy.

The patch adds a prototype for
gen75_cmd_buffer_emit_state_base_address(), which I assume was
intended to be used in this if-statement, and the commit summary says
"Incidentally, this should fix MOCS settings for dynamic and surface
state on Haswell." but other than the useless is_haswell check your
patch removes it didn't touch anything related to Haswell.

Jason should really take a look. Clearly /something/ is wrong.

[Mesa-dev] [PATCH RFC 2/8] nvc0: bind images for 3d/cp shaders on GM107+

[Samuel Pitoiset]

On Maxwell, images binding is slightly different (and much better)
regarding Fermi and Kepler because a texture view needs to be uploaded
for each image and this is going to simplify the thing a lot.

[Mesa-dev] [PATCH RFC 1/8] nvc0: increase the tex handles area size in the driver cb

[Samuel Pitoiset]

Currently, we can store 32 tex handles of 32-bits integer each and
that fits perfectly with the underlying hardware except on GM107+
which requires to upload a texture view for each images.

This patch increases the number of storable texture handles in the
driver constant buffer from 32 to 40 because we expose 8 images.

[Mesa-dev] [PATCH RFC 0/8] nvc0: ARB_shader_image_load_store for Maxwell

[Samuel Pitoiset]

Hi folks,

This series adds support for ARB_shader_image_load_store (GL 4.2) and
ARB_shader_image_size (GL 4.3) on Maxwell GPUs.

Maxwell family is slightly different regarding Fermi and Kepler because it
requires to use a texture view for each images. But this is actually quite
fine because the underlying hardware will handle a bunch of things that we
needed to do in software for previous generations.

However, this series *WILL NOT ENABLE* ARB_shader_image_load_store by default
for the following reasons:

a) Some subtests in arb_shader_image_load_store-atomicity totally hangs the
GPU because there is a race condition. The code is a loop which uses the
result of the surface atomic operation as the condition. The only way for
fixing this bad is to implement a sched calculator pass for Maxwell.
This actually allows to define read/write barriers like the blob does for
this specific case, and this might also improve performance.

b) Maxwell currently only exposes GL 3.3 because tessellation has still not
been figured out (I'm working on this but it's quite hard). So enabling the
extension is not going to help until this part is done.

To sum up, this series add "basic" support for images but it should work
in most cases.

Please review,
Thanks!

no, I don't think dependencies would really help me..

This issue I'm chancing down is a race condition which, I think,
amounts to we initially flush a batch when we don't think we need to
wait for it to complete, and later get a flush_resource() or a flush()
and realize we did actually need it to complete, but no longer have a
ref to the batch (or it's contained fence)..

So I think this might end up being useful to me in some cases.. but
the implementation only works for a single threaded queue (which is
all I need).  I could also just put a helper in my driver code.

Opinions?


What do you need it for? ISTR Marek had a half-finished patch for 
dependencies, maybe that does what you need and is more expressive?

[Mesa-dev] [PATCH 5/7] i965: Move load_interpolated_input/barycentric_* intrinsics to the top.

[Kenneth Graunke]

Currently, i965 interpolates all FS inputs at the top of the program.
This has advantages and disadvantages, but I'd like to keep that policy
while reworking this code.  We can consider changing it independently.

The next patch will make the compiler generate PLN instructions "on the
fly", when it encounters an input load intrinsic, rather than doing it
for all inputs at the start of the program.

To emulate this behavior, we introduce an ugly pass to move all NIR
load_interpolated_input and payload-based (not interpolator message)
load_barycentric_* intrinsics to the shader's start block.

This helps avoid regressions in shader-db for cases such as:

   if (...) {
  ...load some input...
   } else {
  ...load that same input...
   }

which CSE can't handle, because there's no dominance relationship
between the two loads.  Because the start block dominates all others,
we can CSE all inputs and emit PLNs exactly once, as we did before.

Ideally, global value numbering would eliminate these redundant loads,
while not forcing them all the way to the start block.  When that lands,
we should consider dropping this hacky pass.

Again, this pass currently does nothing, as i965 doesn't generate these
intrinsics yet.  But it will shortly, and I figured I'd separate this
code as it's relatively self-contained.

[Mesa-dev] [PATCH 4/7] i965: Add a pass to demote sample interpolation intrinsics.

[Kenneth Graunke]

When working with a non-multisampled render target, asking for "sample"
interpolation locations doesn't make sense.  We demote them to centroid.

In a couple of patches, brw_compute_barycentric_modes will begin looking
at these intrinsics to determine the barycentric modes.  fs_visitor also
will use them to code-generate pixel interpolator messages or payload
references.  Handling the "but what if it's not MSAA?" logic ahead of
time in a NIR pass simplifies things and prevents duplicated logic.

This patch doesn't actually do anything useful yet as we don't generate
these intrinsics.  I decided to keep it separate as it's self-contained,
in the hopes of shrinking the "convert everything" patch for reviewers.

[Mesa-dev] [PATCH 6/7] i965: Rewrite FS input handling to use the new NIR intrinsics.

[Kenneth Graunke]

This eliminates the need to walk the list of input variables, recurse
into their types (via logic largely redundant with nir_lower_io), and
interpolate all possible inputs up front.  The backend no longer has
to care about variables at all, which eliminates complications from
trying to pack multiple variables into the same location.  Instead,
each intrinsic specifies exactly what's needed.

This should unblock Timothy's work on GL_ARB_enhanced_layouts.

Each load_interpolated_input intrinsic corresponds to PLN instructions,
while load_barycentric_at_* intrinsics correspond to pixel interpolator
messages.  The pixel/centroid/sample barycentric intrinsics simply refer
to payload fields (delta_xy[]), and don't actually generate any code.

Because we use a single intrinsic for both centroid-qualified variables
and interpolateAtCentroid(), they become indistinguishable.  We stop
sending pixel interpolator messages for those, and instead use the
payload provided data, which should be considerably faster.

On Broadwell:

total instructions in shared programs: 9067751 -> 9067570 (-0.00%)
instructions in affected programs: 145902 -> 145721 (-0.12%)

HURT: 10

GAINED: 3

The differences mostly appear to be slight changes in MOVs.

While my intention is that the new intrinsics should be usable by all
drivers, we need to make them optional until all drivers switch.

This doesn't do anything yet, but I added it as a separate patch to
keep the interface churn separate for easier review.

[Mesa-dev] [PATCH 1/7] nir: Add new intrinsics for fragment shader input interpolation.

[Kenneth Graunke]

Backends can normally handle shader inputs solely by looking at
load_input intrinsics, and ignore the nir_variables in nir->inputs.

One exception is fragment shader inputs.  load_input doesn't capture
the necessary interpolation information - flat, smooth, noperspective
mode, and centroid, sample, or pixel for the location.  This means
that backends have to interpolate based on the nir_variables, then
associate those with the load_input intrinsics (say, by storing a
map of which variables are at which locations).

With GL_ARB_enhanced_layouts, we're going to have multiple varyings
packed into a single vec4 location.  The intrinsics make this easy:
simply load N components from location .  However,
working with variables and correlating the two is very awkward; we'd
much rather have intrinsics capture all the necessary information.

Fragment shader input interpolation typically works by producing a
set of barycentric coordinates, then using those to do a linear
interpolation between the values at the triangle's corners.

We represent this by introducing five new load_barycentric_* intrinsics:

- load_barycentric_pixel (ordinary variable)
- load_barycentric_centroid  (centroid qualified variable)
- load_barycentric_sample(sample qualified variable)
- load_barycentric_at_sample (ARB_gpu_shader5's interpolateAtSample())
- load_barycentric_at_offset (ARB_gpu_shader5's interpolateAtOffset())

Each of these take the interpolation mode (smooth or noperspective only)
as a const_index, and produce a vec2.  The last two also take a sample
or offset source.

We then introduce a new load_interpolated_input intrinsic, which
is like a normal load_input intrinsic, but with an additional
barycentric coordinate source.

The intention is that flat inputs will still use regular load_input
intrinsics.  This makes them distinguishable from normal inputs that
need fancy interpolation, while also providing all the necessary data.

This nicely unifies regular inputs and interpolateAt functions.
Qualifiers and variables become irrelevant; there are just
load_barycentric intrinsics that determine the interpolation.

[Mesa-dev] [RFC] gallium/u_queue: add barrier function

[Rob Clark]

Helper to block until all previous jobs are complete.
---
So I think this might end up being useful to me in some cases.. but
the implementation only works for a single threaded queue (which is
all I need).  I could also just put a helper in my driver code.

Opinions?

[Mesa-dev] [Bug 96979] Mesa 10.5.7 implementation error: Trying to disable permanently enabled extensions

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=96979

Bug ID: 96979
   Summary: Mesa 10.5.7 implementation error: Trying to disable
permanently enabled extensions
   Product: Mesa
   Version: 10.5
  Hardware: Other
OS: All
Status: NEW
  Severity: normal
  Priority: medium
 Component: Mesa core
  Assignee: mesa-dev@lists.freedesktop.org
  Reporter: b7.10110...@gmail.com
QA Contact: mesa-dev@lists.freedesktop.org

I was trying to set up an environment looking as on i915 system, with actual
device being a Haswell GPU. I used the following commands to get lists of
extensions:

# get information about supported extensions on i915 machine
glxinfo -s | grep GL_ | cut -f 5 -d ' ' | sort | uniq > glxinfo.i915

# same on Haswell machine
glxinfo -s | grep GL_ | cut -f 5 -d ' ' | sort | uniq > glxinfo.haswell

Now on Haswell system I do this to disable the extensions not present on i915
system:

MESA_GL_VERSION_OVERRIDE=1.4 MESA_EXTENSION_OVERRIDE="$(diff -u
~/Dropbox/glxinfo.{haswell,i915} | grep '^-GL' | tr '\n' ' ')" gdb -ex r
glxinfo

And here's the result:

name of display: :1
Mesa 10.5.7 implementation error: Trying to disable permanently enabled
extensions: GL_APPLE_texture_max_level GL_EXT_color_buffer_float

The main problem being here the "Mesa 10.5.7 implementation error". On i915
Mesa version is 10.5.9, so seems it should be similar in its permanently
enabled extensions list.

fyi, I guess also add:

   tab_width = 4

and not sure if there is a way to tell it to use k rules?

But looks like a good idea to me, thanks :-)

It's too bad emacs doesn't just do editorconfig out of the box, but it
makes sense to have something that other editors can easily handle (and
that makes so much more sense than emacs files).

[Mesa-dev] [PATCH 1/3] mesa: automake: list builddir before srcdir

[Emil Velikov]

From: Emil Velikov 

In the case of building in out-of-tree fashion, while having generated
in-tree sources, the latter, likely stale, files will be used by the
compiler.

Flip the order so prevent any issue that this may cause.

Ok, this happens as PIPE_OS_HAIKU isn't defined that early in
u_debug.h, thus the header is not included

 All of this/these can be simplified, by using a local header which
 includes gralloc_drm_handle.h (if possible) and alternatively
 providing dummy defines and static inline function(s).

 This (s/NULL/0/) can live in as the static inline
 gralloc_drm_get_gem_handle() in our local header.

[Mesa-dev] [PATCH 11/11] swr: [rasterizer core] introduce simd16intrin.h

[Tim Rowley]

Refactoring to leave existing simd_* intrinsics in "simdintrin.h" unchanged,
adding corresponding simd16_* intrinsics in "simd16intrin.h" on the side,
with emulation, that we can use piecemeal, rather than the all-or-nothing
approach to bring up avx512.

[Mesa-dev] [PATCH 05/11] swr: [rasterizer] attribute swizzling and linkage

[Tim Rowley]

Add support for enhanced attribute swizzling. Currently supports constant
source overrides to handle PrimitiveID support. No support yet for input
select swizzling or wrap shortest. Removes obsoleted linkageMask and
associated code.
