egl: Fix inclusion of egl.h+mesa_glinterop.h

Previously clang would warn about redefinition of typedef EGLDisplay. Avoid
this by adding preprocessor guards to mesa_glinterop.h and including it
after EGL.h is indirectly included.

Same thing can happen with dri2_initialize_wayland_swrast, would be good 
to fix both at one go.


and that is actually what the patch does, both call dri2_display_destroy 
the same way :)

This particular test sets a 0 x 0 scissor region.  All the 
pipe_scissor_state members are zero and when the state tracker does a 
memcmp() with its copy it sees no difference and skips the call to 
pipe->set_scissor_state().


-Brian



This bug looks similar in nature to the uninitialized fb (see
8bfe451ed30918244618608871423b2a72cf9767) and I thought that was
impossible to hit with gl state tracker...

[Mesa-dev] [PATCH] egl/dri2: only destroy created objects

[Michael Olbrich]

dri2_display_destroy may be called by dri2_initialize_wayland_drm() if
initialization fails. In this case, these objects may not be initialized.

Re: [Mesa-dev] V2 radeonsi use STD430 packing of UBOs by default

[Marek Olšák]

I have to conclude that I don't see a way to use LOAD with CONSTBUF
and keep the same performance as before. It looks like there are some
deficiencies in our compiler stack that are unfixable in Mesa alone.

 Odd. Do you see the same change in TGSI?

 As far as I can tell this is because after this chnage we end up with
 large sections of consecutive loads. Any thoughts on avoid this?

Re: [Mesa-dev] V2 radeonsi use STD430 packing of UBOs by default

[Marek Olšák]

Interesting. It may be that glsl_to_tgsi uses copy propagation to fold
those CONST loads into operands, which puts them next to their uses in LLVM.

I guess LLVM doesn't understand that s_buffer_load_dword loads from
immutable dereferenceable memory. It would benefit from mayLoad = 0 in
this case I think.

 I'm a little unsure what to do with this now. Below is my shader-db
 results, the majority of negative changes are from Natural Selection

 I looked at some dumps of the worst Natural Selection 2 shaders and
 it seems to just be scheduling differences causing the regressions.

 I tested with sisched but that just made things even worse.

 Obviously we should be aiming to improve the schedulare, but since
 this regresses things and I have no evidence of it helping anything
 it makes the case for adding it pretty weak.

 Thoughts??

This st/mesa change should be a separate patch. Also, ctx->Const is
typically initialized in st_extensions.c and CAPs are also checked
mostly there. If you split this patch into two, you can add my Rb to
both IF you initialize ctx->Const... in st_extensions.c.

Other than that, for patches 1-3, 5-6:

Copy and pasted comments from the last time this was sent:

Seems reasonable. This pattern is also happening in glsl_lexer.ll maybe 
we should do this there also?


It might also make sense to add a comment here to say why we don't use 
linear_strdup(), so the optimisation doesn't get removed in future.


With that:

This little series changes things around so that, instead of passing MOCS

hopefully, if we ever do anything crazy in the future, we can share it
between GL and Vulkan.  Unfortunately, surfaces are not the only places
where MOCS is used.  It also shows up in vertex buffers, index buffers, and
streamout buffers.  However those are always set to the platform equivalent
of I915_MOCS_CACHED (and that's not all that liable to change) so they're
not particularly interesting.

If people like this approach, I'd like to Cc it to stable for 17.2 because
it has the side-effect of making Vulkan MOCS a bit more sane.

I guess this is okay.  I'm not crazy about it, mostly because the logic is
still spread out in a bunch of places.  If there was a vertex buffer usage
bit and we could handle that there, I think that would be nice, even if it
doesn't otherwise seem relevant to ISL.  *shrug*


Yeah, vertex buffers make this a bit awkward.  I wish there were a better 
way than scattering things around more.  I'm honestly not sure if this 
series improves the scattering or not.



Having ISL do this itself rather than passing in values makes sense.

[Mesa-dev] [PATCH] radv: Disable multilayer & multilevel DCC.

[Bas Nieuwenhuizen]

The current DCC init routine doesn't account for initializing a
single layer or level. Multilayer seems hard for small textures on
pre-GFX9 as tre metadata for the layers can be interleaved. For
GFX9 multilevel textures are a problem for similar reasons.

So just disable this for now, until we handle the texture modes
correctly.

Re: [Mesa-dev] [PATCH 1/6] blorp: Turn anv_CmdCopyBuffer into a blorp_buffer_copy() helper.

On August 29, 2017 3:14:08 PM Chris Wilson  wrote:


Quoting Kenneth Graunke (2017-08-29 22:28:38)

Anvil already had code to copy between two buffer objects in the most
efficient way possible, using large bpp copies, then smaller bpp copies.

This patch moves that logic into BLORP as blorp_buffer_copy(), so we
can reuse it in i965 as well.


Just some food for thought...

The render access pattern is terrible for wide linear buffers, as the
pixel block ends up being scattered across many pages, thrashing the TLB.
But if instead of telling it to copy as wide as possible, you just
limited it to a stride of 4096/4 (if memory serves 4 is the largest
pixel block height) then each pixel block is located inside just one
page (and hopefully cluster across the eu, further reducing the stride
may help if the spread ends up taller than wider).


Yes, some benchmarking would have to be done to truly substantiate Ken's 
claim.  I think you may be right that the access patterns aren't great.  If 
we hit the case where you do a one pixel tall blit, that's also not good.  
I think there is a lot of time that could be sink into making this more 
efficient.

Re: [Mesa-dev] [PATCH 1/7] gallium: add CONSTBUF type to tgsi_file_type

[Marek Olšák]

I'd like CONSTBUF to stay. I think CONST is already too overloaded.

If we start treating CONST[0] and CONST[0][0] differently, things are
just going to get more ugly. If the second dimension is unspecified,
it's implied to be 0. TGSI doesn't allow specifying the second
dimension index and omit the first dimenstion, which means it can't
say that CONST[0] is constbuf 0 without changing existing conventions.

 I always considered CONST[0] == CONST[0][0]. Technically they're not,
 since once has the second dimension in the TGSI encoding while the
 other doesn't. But practically,

 MOV TEMP[0], CONST[0]

 and

 MOV TEMP[0], CONST[0][0]

 are in every way identical. Currently st/mesa will just use CONST[0]
 everywhere, never adding the 2nd dimension.

Just some food for thought...

The render access pattern is terrible for wide linear buffers, as the
pixel block ends up being scattered across many pages, thrashing the TLB.
But if instead of telling it to copy as wide as possible, you just
limited it to a stride of 4096/4 (if memory serves 4 is the largest
pixel block height) then each pixel block is located inside just one
page (and hopefully cluster across the eu, further reducing the stride
may help if the spread ends up taller than wider).

Using a semi-colon would be clearer:

/* Cache in L3; LLC and eLLC use PTE */

otherwise it might be possible to read it as "Cache in L3, LLC, and eLLC ..."

I guess this is okay.  I'm not crazy about it, mostly because the logic is
still spread out in a bunch of places.  If there was a vertex buffer usage
bit and we could handle that there, I think that would be nice, even if it
doesn't otherwise seem relevant to ISL.  *shrug*

Having ISL do this itself rather than passing in values makes sense.

[Mesa-dev] [PATCH 1/6] blorp: Turn anv_CmdCopyBuffer into a blorp_buffer_copy() helper.

[Kenneth Graunke]

Anvil already had code to copy between two buffer objects in the most
efficient way possible, using large bpp copies, then smaller bpp copies.

This patch moves that logic into BLORP as blorp_buffer_copy(), so we
can reuse it in i965 as well.

[Mesa-dev] [PATCH 4/6] i965: Add PIPE_CONTRTOL_DATA_CACHE flush to brw_emit_mi_flush().

[Kenneth Graunke]

Although we're phasing out brw_emit_mi_flush(), we still use it in some
places in order to "flush everything".  In a number of those places, we
write data to a buffer that we may then bind as an image surface, SSBO,
or atomic buffer.  Those usages require us to flush the data cache.

[Mesa-dev] [PATCH 5/6] i965: Always flush caches after blitting to a GL buffer object.

[Kenneth Graunke]

When we blit data into a buffer object, we may need to invalidate any
caches that might contain stale data, so the new data becomes visible.

For example, if the buffer object is bound as a vertex buffer, we need
to invalidate the vertex fetch cache.

While this flushing was missing, it usually happened implicitly for
non-obvious reasons: we're usually on the render ring, and calling
intel_emit_linear_blit() would require switching to the BLT ring,
causing an implicit flush.  This likely provoked the kernel to do
PIPE_CONTROLs on our behalf.  Although, Gen4-5 wouldn't have this
behavior.  At any rate, we should do it ourselves.

[Mesa-dev] [PATCH 3/6] i965: Add a brw_blorp_copy_buffers() command.

[Kenneth Graunke]

This exposes the new blorp_copy_buffer() functionality to i965.
It should be a drop-in replacement for intel_emit_linear_blit()
(other than the arguments being backwards, for consistency with BLORP).

I think that "bool" doesn't need "!!" and automatically converts the
value to true/false, but I'm not 100% sure. Anyway, the series is:

[Mesa-dev] [PATCH 4/8] glcpp: Use string_buffer for line continuation removal

[Thomas Helland]

Migrate removal of line continuations to string_buffer. Before this
it used ralloc_strncat() to append strings, which internally
each time calculates strlen() of its argument. Its argument is
entire shader, so it multiple time scans the whole shader text.

[Mesa-dev] [PATCH 6/8] glcpp: Use Bloom filter before identifier search

[Thomas Helland]

From: Vladislav Egorov 

Absolute majority of identifiers in shaders are not macro references.
Many shaders don't use preprocessing macros at all. Almost all
queries to parser->defines hash-table will be unsuccessful. Note
that all predefined macros start either with "GL_" or with "__".
Moreover, even user-defined macros are usually use upper case, while
ordinary identifiers use lower case. It's easy to detect macros just
looking on the first two characters of their name. So it makes sense
to make a quick identifier lookup in a Bloom filter before making
relatively expensive hash-table search call.

Many schemes of Bloom are possible, but it seems that two mini 64 bit
Bloom tables -- one for the 1st identifier's char, one for the second
identifier's char -- with one trivial hash-function (6 lowest bits of
the char) work very well. Considering that Latin-1 alphabetic chars
and _ occupy positions from 65 to 122, every character will have its
bit position in 64-bit word, distinguishing lower and upper case.

Some games do things like "#define float4 float", this scheme would
not help here, it barely improves heavy users of preprocessor like
Talos Principle, but in general it works pretty well. In my shader-db
it eliminates 90%+ hash table queries during preprocessing stage.
One 64-bit Bloom table working on only 1st or only 2nd char will
eliminate ~70-80% queries.

For simplicity use the same scheme for both 32-bit and 64-bit archs.
32-bit archs still have pretty efficients ways to do 64-bit shifts.

[Mesa-dev] [PATCH 2/8] util: Add tests for the string buffer

[Thomas Helland]

More tests could probably be added, but this should cover
concatenation, resizing, clearing, formatted printing,
and checking the length, so it should be quite complete.

V2: Address review feedback from Timothy, plus fixes
   - Use a large enough char array
   - Actually test the formatted appending
   - Test that clear function resets string length

[Mesa-dev] [PATCH 5/8] glcpp: Avoid unnecessary call to strlen

[Thomas Helland]

Length of the token was already calculated by flex and stored in yyleng,
no need to implicitly call strlen() via linear_strdup().

[Mesa-dev] [PATCH 0/8] Resend of preprocessor series

[Thomas Helland]

This is a resend of the string buffer implementation and
related patches sent out back in May. I've done one more
change to the string buffer; using u_string.h for a compatible
vsnprintf version to reduce the code even more. I've not been
able to test this due to two build breakages (xmlpool and dri)
that I'm still trying to figure out of. But since I promised
to send these out this evening, I'm sending them untested.
I did test them thoroughly the last time around though,
so I believe it should be mostly good as long as I haven't
messed up the rebasing. I believe the string buffer part of
the series is the most important; the rest I've not really
gotten around to performance test much.

Thomas Helland (7):
  util: Add a string buffer implementation
  util: Add tests for the string buffer
  glsl: Change the parser to use the string buffer
  glcpp: Use string_buffer for line continuation removal
  glcpp: Avoid unnecessary call to strlen
  port to gtest
  fix test makefile

  glcpp: Use Bloom filter before identifier search

[Mesa-dev] [PATCH 1/8] util: Add a string buffer implementation

[Thomas Helland]

Based on Vladislav Egorovs work on the preprocessor, but split
out to a util functionality that should be universal. Setup, teardown,
memory handling and general layout is modeled around the hash_table
and the set, to make it familiar for everyone.

A notable change is that this implementation is always null terminated.
The rationale is that it will be less error-prone, as one might
access the buffer directly, thereby reading a non-terminated string.
Also, vsnprintf and friends prints the null-terminator.

V2: Address review feedback from Timothy and Grazvydas
   - Fix MINGW preprocessor check
   - Changed len from uint to int
   - Make string argument const in append function
   - Move to header and inline append function
   - Add crimp_to_fit function for resizing buffer

V3: Move include of ralloc to string_buffer.h

V4: Use u_string.h for a cross-platform working vsnprintf

I like the proposal. It is better having a unique opcode for setting the
rounding mode. Changed for v2 of this patch.

Well pointed, we already realized that it was missing while debugging
the latency problem of the control register. It was hiding the problem
re-scheduling the cr0 modification to the beginning of the shader.

At the end we removed  MODE_UNSPECIFIED as it isn't really needed and we
include Round Up and Down in the enum assignation based using the PRM
values. Also renamed RTE for RTNE to maintain coherence with nir
conversion modifiers using the same acronym as PRM.

+enum PACKED brw_rnd_mode {

+};

I have a doubt about how to avoid the magic constants to close the v2 of
this patch. One approach would be using the same code structure and
taking advantage using the codification of rounding field. This way we
just formula and expect that the C compiler optimizer to guess that the
immediate value is a constant.

switch (mode) {
    case BRW_RND_MODE_RTZ:
-  inst = brw_OR(p, brw_cr0_reg(0), brw_cr0_reg(0),
brw_imm_ud(0x0030u));
+  inst = brw_OR(p, brw_cr0_reg(0), brw_cr0_reg(0),
brw_imm_ud(((unsigned int) mode << 4)));
   break;
-   case BRW_RND_MODE_RTE:
-  inst = brw_AND(p, brw_cr0_reg(0), brw_cr0_reg(0),
brw_imm_ud(0xffcfu));

brw_imm_ud(((unsigned int) mode << 4) | ~0x0030u));
   break;
    default:

Another approach could be to implement a general solution for all
supported rounding modes by the hw including Round Up and Down using
bitwise operations.

/**

[Mesa-dev] [Bug 102454] glibc 2.26 doesn't provide anymore xlocale.h

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=102454

--- Comment #1 from Emil Velikov  ---
The patch in the bug report isn't quite right (aka remove the header and guards
all together).

Instead one should add a configure check - AC_LINK_IFELSE() ... which:
 - includes xlocale.h reusing the HAVE_XLOCALE_H guard
 - references strtod_l w/o any guard, setting a macro HAVE_FOO
Then update the code
 - swap the __GNU_SOURCE guards through the file with HAVE_FOO
 - HAVE_XLOCALE_H should guard _only_ the header inclusion

Oh, uh… I think this might also be in a local patch ^^
We have a bunch of patches like that, that I want to upstream, but
not enough bandwidth and too many high priority tasks lining up.
I'll try and have a look tomorrow for the query_surface hook.

I'm surprised to hear you say that. I've tested with gcc-4.9.4, 6.4.0,
7.1.0; and clang-4.0, and none of them warn about {}

I think when we went through this before (in NIR) we couldn't use {}
because it needs to compile with MSVC, and MSVC doesn't allow that in
C.

I don't really understand the nuances of {0}, {0,}, {{0}}, etc, and I
get the sense that that's the case for nearly everyone else as well.

The most prominent bug I see in all of this is that {} isn't part of
standard C (it is part of standard C++!)

Having another look, we seems to be rather inconsistent when we set
them - see below.
At the same time, I doubt any !X11 dEQP resize tests work:
 - iirc there's no wayland/drm/surfaceless support
 - none of the three has a .query_surface hook

-Emil

X11/dri2
 - create_*_surface, all but !pbuffer
 - query_surface via xcb_get_geometry

X11/dri3:
 - create_*_surface, all
 - query_surface via xcb_get_geometry

drm
 - create_*_surface, all (window only)
 - query_surface - no hook

surfaceless
 - create_*_surface, none (pbuffer only)
 - query_surface  - no hook

wayland
 - create_*_surface, none (window only)
 - query_surface  - no hook

[Mesa-dev] [PATCH 2/2] i965: Implement ARB_indirect_parameters

[Plamena Manolova]

We can implement ARB_indirect_parameters for i965 by
taking advantage of the conditional rendering mechanism.
This works by issuing maxdrawcount draw calls and using
conditional rendering to predicate each of them with
"drawcount > gl_DrawID"

No, I cannot imagine it could cause any change. It's really just
changing when a float -> double conversion happens.

[Mesa-dev] [PATCH 2/2] winsys/amdgpu: set AMDGPU_GEM_CREATE_LOCAL if possible

[Christian König]

From: Christian König 

When the kernel supports it set the local flag and
stop adding those BOs to the BO list.

Can probably be optimized much more.

[Mesa-dev] [PATCH 1/2] radeonsi: set a per-buffer flag that disables inter-process sharing (v4)

[Christian König]

From: Marek Olšák 

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

v2: It shouldn't crash anymore, but the kernel will reject the new flag.
v3 (christian): Rename the flag, avoid sending those buffers in the BO list.
v4 (christian): Remove setting the kernel flag for now

We actually have a local patch here that replaces this `-1`
initialisation with the dimensions of the wayland `window`:

This apparently fixes dEQP crashes caused by an assert:
deRandom.hpp:93: Unknown function: Assertion `min <= max' failed.

No dEQP test is mentioned on our patch, but I think this happened on
dEQP-EGL.functional.resize.surface_size.*

Scratch that - I misread 36 as 32, which would have left a 4 byte

I guess I'll add a comment in the kernel.

Unless I failed at math - the struct does not seem compat safe.
That is sizeof(struct drm_i915_perf_oa_config) varies across 32/64bit builds.


Hmm... What's not compat safe in there? :

struct drm_i915_perf_oa_config {
/** String formatted like "%08x-%04x-%04x-%04x-%012x" */
char uuid[36];

__u32 n_mux_regs;
__u32 n_boolean_regs;
__u32 n_flex_regs;

__u64 mux_regs_ptr;
__u64 boolean_regs_ptr;
__u64 flex_regs_ptr;
};




Some padding should fix it.

Mildly curious:
Did you pipe the series through ezbench for perf testing?
Wondering if the inline and fabsf -> babs changes made any noticeable impact.

I pushed it a couple hours before your email, sorry.
/me needs to learn not to push stuff right away, let it sit for a bit...

As for "why we don't copy the whole file", we essentially do, but we
keep our local platforms additions (WL, GBM, X11 on MacOS, and Haiku),
right? Or is there something else?

[Mesa-dev] [PATCH v2 5/5] i965: add a debug option to disable oa config loading

[Lionel Landwerlin]

This provides a good way to verify we haven't broken using the perf
driver on older kernels (which don't have the oa config loading
mechanism).

without setting up a full blown draw)?  If so perhaps you could get
away with leaving some extra space at the end of your uniform buffer
that you copy driver internal uniforms into before kicking the draw?

fwiw, freedreno does have driver specific uniforms, see
ir3_driver_param.  Although normal uniforms (ie. non-UBO) get copied
into internal memory, so I just upload driver specific uniforms (as
needed) and immediates to the tail of the uniform memory before the
draw.

How about when xgetbv() returns say 6 or 7 (amongst others)?

Also keep in mind that the file depends on multiple defines. Based on a _very_
old play with Mesa + cppcheck, the latter was tripping quite often, producing
false positives.

The OS/compiler request does not sound that unreasonable ;-)

I think you missed the point. Any expression ANDed with 6 will be != 6.

OS, compiler and arch independent. For the record, Linux, gcc and x86_64,
although I used a static analyser called cppcheck to find this bug.

Right. So I guess as weston-nested is updated to use wl_dmabuf we

Right, that's why I flipped the order ;-) Although they are
considering breaking the ABI with the v2.0 branch.

For which I have some sweet patches - purge wl_drm, forbid use of card nodes...
Need to finish that one of the of these days.

--- Comment #1 from Gert Wollny  ---
It would be helpful to add on which OS and with which compiler and for what
architecture you were compiling mesa, because depending on the build
environment xgetbv() may simply return 0 as a fallback (see lines 259-277 in
the same file).

[Mesa-dev] [PATCH 5/5] i965: add a debug option to disable oa config loading

This provides a good way to verify we haven't broken using the perf
driver on older kernels (which don't have the oa config loading
mechanism).

[Mesa-dev] [PATCH 0/5] i965: add support for loadable OA configs

[Lionel Landwerlin]

Hi,

Some recent work in the i915 kernel driver enables us to load OA
configs from userspace, so new configs can be deployed without having
to modify the kernel. This series makes use of this feature in i965 if
available.

Cheers,

Re: [Mesa-dev] [PATCH 0/9] spirv: Improve logging and error handling

[Tapani Pälli]

LGTM, patches 1-5

Reviewed-by: Tapani Pälli 

With these changes we can add a nir_spirv_debug_callback that has 
instance and shader object in private data so that we can call 
VK_EXT_debug_report functionality from anv_pipeline code.

This series has two objectives:

  1) Improve logging to provide more detail and provide hooks so we can
 plumb errors and warnings through to debug_report extensions.

  2) Improve error handling so that not all errors result in killing the
 process.  This is done by adding new spv_fail and spv_assert helpers
 which log the error and longjump back to a point where we can clean up
 and return NULL without crashing.

There is still quite a ways to go with error handling if we want to be able
to guarantee that we won't crash given an arbitrary stream of bytes.
However, this should at least be a step in the right direction.  There are
probably at least a couple of cases where I could have left an assert() as
an actual "kill the process" assert because it's testing for internal
consistency.  However, the vast majority of them are validation checks so
it seemed better to just search+replace them all and we can convert the few
that we want back to real asserts later.

I haven't seen much use of it, myself. It's also only really useful
for wl_drm; I'd prefer to push zwp_linux_dmabuf instead. It also
relies on a more perfect proxying of wl_drm than we necessarily
actually implement.

The one thing it provides over and above wl_dmabuf is device
advertisement, to guide the implementation towards a particular GPU.
So maybe it makes sense to keep it just for that, purely for render
nodes.

Also VA-API still uses wl_drm, so we need to wean that away from it first.
