EGL Extension #XXX
|
|
|
|
Extension Type
|
|
|
|
EGL client extension
|
|
|
|
Dependencies
|
|
|
|
This extension is written against the wording of the 2014.08.27 revision
|
|
of the EGL 1.5 Specification.
|
|
|
|
Overview
|
|
|
|
This extension provides a mechanism to lower the config selection priority
|
|
of the configs returned by eglChooseConfig. A new config attribute is
|
|
introduced, providing a way for the implementation to group configs into
|
|
different config selection categories. The config selection priorities of
|
|
all the configs in one category may be higher or lower than the ones in
|
|
other categories. The config selection priorities in one category follow
|
|
the rules of eglChooseConfig.

Additions to the EGL 1.5 Specification
|
|
|
|
In section 3.4 "Configuration Management", under the "Buffer Descriptions
|
|
and Attributes" heading, append to table 3.1 the following:
|
|
|
|
"EGL_CONFIG_SELECT_GROUP_MESA | integer | the config select group"
|
|
|
|
In section 3.4 "Configuration Management", under the "Other EGLConfig
|
|
Attribute Descriptions" heading, append to the end the following:
|
|
|
|
"The attribute EGL_CONFIG_SELECT_GROUP_MESA is used to specify the config
|
|
selection category of the config. Configs in the i-th category have a higher
|
|
config selection priority than those found in the (i+1)-th category.
|
|
|
|
"The attribute EGL_CONFIG_SELECT_GROUP_MESA is used by the implementation to
|
|
override the default sorting rules, by collecting configurations into
|
|
groups. It is not accepted by the <attrib_list> parameter of
|
|
eglChooseConfig, but it is accepted as the <attribute> in
|
|
eglGetConfigAtrrib."
|
|
|
|
In section 3.4 "Configuration Management", under the "Sorting of EGLConfigs"
|
|
heading, append to table 3.4 the following:
|
|
|
|
"EGL_CONFIG_SELECT_GROUP_MESA | 0 | Ignore | Smaller | 0"
|
|
|
|
In section 3.4 "Configuration Management", under the "Sorting of EGLConfigs"
|
|
heading, append before the list entry which starts with "1. Special: by
|
|
EGL_CONFIG_CAVEAT" the following entry:
|
|
|
|
"0. Smaller EGL_CONFIG_SELECT_GROUP_MESA."
