All mature drivers report shader statistics in various places. GL drivers use util_debug for shader-db's report script. VK drivers use executable statistics feeding the report fossil script. Many drivers also have a magic env var to dump the stats to stdout/stderr in addition to these standard forms. Implementing any of these 3 reports requires doing brittle string processing in C (GL, stdout) or piles of boilerplate (VK). Additionally, the logic gets duplicated in every driver and duplicated between GL and VK. And to add insult to injury, the information is duplicated *again* in the report fossil script :'( This commit introduces a new 'shader statistic framework' that aims to unify statistics reporting across all drivers and across GL&VK. With the new approach, a common XML file defines all the statistics for the tree. The common code introduced here then autogenerates from that XML file an appropriate C header. The header contains a C struct for each ISA, and autogenerated print/report functions. Minimal driver integration is required: just filling out the stats struct and calling the appropriate functions. In this MR, 3 driver families are added as examples. Panfrost/PanVK and Asahi/Honeykrisp are added as "complete" examples. Neither Vulkan driver reported nontrivial executable statistics; with these changes, both report all the same statistics that the GL drivers report. Turnip is also added partially - it's not plumbed into ir3/gallium yet but just using the XML reduces boilerplate a ton for Vulkan statistics. [It is intended for this XML to be consumed also by shader-db's python scripts, but that's not done here.] Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Reviewed-by: Mel Henning <mhenning@darkrefraction.com> Reviewed-by: Mary Guillemard <mary.guillemard@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33814>
