Hello, This is an attempt at exposing Mali Midgard/Bifrost perf counters in a more or less generic way so that they can be used through the pipe_query interface. That should allow one to dump/display those counters using gallium-hud or any tool/lib that uses the GL_AMD_performance_monitor API (apitrace) to query HW counters.
This series adds new hooks to the panfrost_driver driver interface so that both the drm and non-drm drivers can be plugged (I only developped the glue for the DRM driver so far, but can work on the non-DRM driver if needed). Only T860 counters are exposed so far, as this is the platform I tested on. It's been tested with gallium-hud in invisible mode (the driver doesn't support RECT texture, which is needed to display the HUD): List all available counters: # GALLIUM_HUD_VISIBLE=false GALLIUM_HUD=help <app> Dump counters in a directory: # GALLIUM_HUD_VISIBLE=false GALLIUM_HUD_DUMP_DIR=<dump-dir> GALLIUM_HUD=<counter1>,<counter2>,... <app> Should also work with apitrace, but I haven't tested yet.
