The i965 driver has a bunch of code to compare two sets of program keys
and print out the differences. This can be useful for debugging why a
shader needed to be recompiled on the fly due to non-orthogonal state
dependencies. anv doesn't do recompiles, so we didn't need to share
this in the past - but I'd like to use it in iris.
This moves the bulk of the code to the compiler where it can be reused.
To make that possible, we need to decouple it from i965 - we can't get
at the brw program cache directly, nor use brw_context to print things.
Instead, we use compiler->shader_perf_log(), and simply pass in keys.
We put all of this debugging code in brw_debug_recompile.c, and only
export a single function, for simplicity. I also tidied the code a
bit while moving it, now that it all lives in one file.

This legalization pass is meant to handle situations where the source

the hardware and need to be lowered away into separate instructions.
This should be more reliable and future-proof than the current

conversions easily, which obsoletes the lower_conversions pass.

This commit moves our storage image format conversion codegen into NIR
instead of doing it in the back-end. This has the advantage of letting
us run it through NIR's optimizer which is pretty effective at shrinking
things down. In the common case of rgba8, the number of instructions
emitted after NIR is done with it is half of what it was with the
lowering happening in the back-end. On the downside, the back-end's
lowering is able to directly use predicates and the NIR lowering has to
use IFs.

This adds support for the KHR_display extension to the anv Vulkan

perform the necessary operations.
v2: Make sure primary fd is usable
When KHR_display is selected, we try to open the primary node
instead of the render node in case the user wants to use
KHR_display for presentation. However, if we're actually going

Unnecessary GRF bank conflicts increase the issue time of ternary
instructions (the overwhelmingly most common of which is MAD) by
roughly 50%, leading to reduced ALU throughput. This pass attempts to
minimize the number of bank conflicts by rearranging the layout of the
GRF space post-register allocation. It's in general not possible to
eliminate all of them without introducing extra copies, which are
typically more expensive than the bank conflict itself.
In a shader-db run on SKL this helps roughly 46k shaders:
total conflicts in shared programs: 1008981 -> 600461 (-40.49%)
conflicts in affected programs: 816222 -> 407702 (-50.05%)
helped: 46234
HURT: 72
The running time of shader-db itself on SKL seems to be increased by
roughly 2.52%±1.13% with n=20 due to the additional work done by the
compiler back-end.
On earlier generations the pass is somewhat less effective in relative
terms because the hardware incurs a bank conflict anytime the last two
sources of the instruction are duplicate (e.g. while trying to square
a value using MAD), which is impossible to avoid without introducing
copies. E.g. for a shader-db run on SNB:
total conflicts in shared programs: 944636 -> 623185 (-34.03%)
conflicts in affected programs: 853258 -> 531807 (-37.67%)
helped: 31052

total conflicts in shared programs: 1418393 -> 987539 (-30.38%)
conflicts in affected programs: 1179787 -> 748933 (-36.52%)

I'm bringing up Vulkan in the Android container of Chrome OS (ARC++).
On Android, stdio goes to /dev/null. On Android, remote gdb is even more
painful than the usual remote gdb. On Android, nothing works like you
expect and debugging is hell. I need logging.
This patch introduces a small, simple logging API that can easily wrap
Android's API. On non-Android platforms, this logger does nothing fancy.
It follows the time-honored Unix tradition of spewing everything to
stderr with minimal fuss.
My goal here is not perfection. My goal is to make a minimal, clean API,
that people hate merely a little instead of a lot, and that's good
enough to let me bring up Android Vulkan. And it needs to be fast,
which means it must be small. No one wants to their game to miss frames
while aiming a flaming bow into the jaws of an angry robot t-rex, and
thus become t-rex breakfast, because some fool had too much fun desiging
a bloated, ideal logging API.
If people like it, perhaps we should quickly promote it to src/util.
The API looks like this:
#define INTEL_LOG_TAG "intel-vulkan"
#define DEBUG
intel_logd("try hard thing with foo=%d", foo);
n = try_foo(...);
if (n < 0) {
intel_loge("%s:%d: foo failed bigtime", __FILE__, __LINE__);
return VK_ERROR_DEVICE_LOST;
}
And produces this on non-Android:
intel-vulkan: debug: try hard thing with foo=93

As time goes on, extension advertising is going to get more complex.
Today, we either implement an extension or we don't. However, in the
future, whether or not we advertise an extension will depend on kernel
or hardware features. This commit introduces a python codegen framework
that generates the anv_EnumerateFooExtensionProperties functions as well
as a pair of anv_foo_extension_supported functions for querying for the
support of a given extension string. Each extension has an "enable"
predicate that is any valid C expression. For device extensions, the
physical device is available as "device" so the expression could be
something such as "device->has_kernel_feature". For instance
extensions, the only option is VK_USE_PLATFORM defines.
This mechanism also means that we have a single one-line-per-entry table
for all extension declarations instead of the two tables we had in
anv_device.c and the one we had in anv_entrypoints_gen.py. The Python
code is smart and uses the XML to determine whether an extension is an
instance extension or device extension.
