New Behavior
|
|
|
|
To request a display that is backed by a specific graphics device,
|
|
EGL_PLATFORM_ANGLE_DEVICE_ID_HIGH_ANGLE and/or
|
|
EGL_PLATFORM_ANGLE_DEVICE_ID_LOW_ANGLE should be set to the high part and
|
|
low part of the device's ID. If only one attribute is specified, the other
|
|
is assumed to be zero. The device's ID is specific to the platform that
|
|
ANGLE is running on, but should fit into one 64-bit value.
|
|
|
|
If the high part and low part combined is zero, an EGL_BAD_ATTRIBUTE error
|
|
is generated and EGL_NO_DISPLAY is returned.
|
|
|
|
If the ID specified doesn't match any devices on the system, the device
|
|
is selected as described in the EGL_ANGLE_display_power_preference extension.
|
|
|
|
To select a distinct display on a graphics device that may already have
|
|
an existing display in ANGLE's cache, use EGL_PLATFORM_ANGLE_DISPLAY_KEY_ANGLE
|
|
to add a key to the cache entry for this display. The same cached display can
|
|
be re-requested by specifying the same cache value. If this parameter is not
|
|
included, the default value used will be 0.

multiple EGLDisplays from the same graphics device.
|
|
|
|
Version 2, 2022-04-09 (Kimmo Kinnunen)
|
|
- Describe interaction with EGL_ANGLE_display_power_preference,
|
|
EGL_ANGLE_platform_angle_device_id takes precedence.
