Hi folks,
I have been working on a new developer tool called vkpipeline-db, which
is the equivalent of shader-db for Vulkan. This tool is composed of two
parts:
1) A Vulkan layer that allows to capture graphics/compute pipelines
(including states, render pass and shader modules). The layer will
create and store .pipeline_test files into the captured directory which
can be set with VKPIPELINE_DB_CAPTURE_PATH.
2) A runner that allows to replay the capture pipelines in order to get
shader statistics (like number of SGPRs/VGPRs for AMD hardware).
Currently, the runner requires VK_AMD_shader_info because the tool has
been initially developed for RADV. Other Vulkan drivers might want to
implement this extension, or use a different way for getting shader stats.
The RADV team has been using it for weeks, it seems to work correctly
for our needs. Though, I won't be surprised if someone finds bugs
because it's a new tool.
The repository can be found here:
https://cgit.freedesktop.org/mesa/vkpipeline-db
Feel free to test, and send bugs reports/feedback/patches on mesa-dev.
Cheers,
Samuel Pitoiset.
