All supported Mali architectures support these formats, but not +every system-on-chip with a Mali GPU support all these formats. Many lower-end +systems lack support for some BCn formats, which can cause problems when playing +desktop games with Panfrost. To check whether this issue applies to your +system-on-chip, Panfrost includes a ``panfrost_texfeatures`` tool to query +supported formats. + +To use this tool, include the option ``-Dtools=panfrost`` when configuring Mesa. +Then inside your Mesa build directory, the tool is located at +``src/panfrost/tools/panfrost_texfeatures``. Copy it to your target device, +set as executable as necessary, and run on the target device. A table of +supported formats will be printed to standard output. + drm-shim -------- |
