| Compressed texture support |
| ========================== |
| |
| In the driver, Panfrost supports ASTC, ETC, and all BCn formats (e.g. RGTC, |
| S3TC, etc.) However, Panfrost depends on the hardware to support these formats |
| efficiently. 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. |
