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.
