- Mesa config file documentation
-
-
- As of Mesa 3.1 beta 2, a config file can be used to configure various
- Mesa parameters. For example, extensions can be enable/disabled,
- glHints can be specified, etc. More config options will be added
- in the future.
-
- The config file uses a Lisp-like syntax.
-
- Here's Keith's description of the file with a few examples.
-
-
-
- ;; -*-lisp-*-
- ;;
- ;; KW: New mesa configuration file, syntax following a lisp style.
- ;;
- ;; valid syntax:
- ;;
- ;; (config-mesa version configs)
- ;;
- ;; where:
- ;; version - is the version number of mesa for which the configuration
- ;; was written. Future versions will use this to check for upwards
- ;; compatibility. There is however no guarentee that old configurations
- ;; will continue to be respected.
- ;;
- ;; configs - is a list of valid configuration lists, as specified by:
- ;;
- ;; (default-hint variable value)
- ;; (disable-extension name)
- ;; (fx-catch-signals {true|false})
- ;;
- ;; Mesa will look for an environment variable MESA_CONFIG, and try to
- ;; execute that profile. Otherwise, it will fallback to the profile
- ;; with the same name as the current mesa version. As default
- ;; profiles should normally be empty or near-empty, this should be
- ;; sufficiently powerful.
- ;;
-
-
- ;; Guareenteed to be an empty config.
- ;;
- (config-mesa empty ())
-
-
- ;; Default profile - should normally be an empty list of
- ;; configurations.
