Class EXTImageImplicitSyncControl
This extension allows a client to selectively use implicit or explicit synchronization mechanisms when addressing externally-imported
EGLImages
. A new token is added to EGLImage
creation which allows the client to select whether a platform's implicit synchronization
will be in use for a buffer imported into EGLImage
.
Heterogeneous systems (supporting multiple APIs, mixed legacy/updated clients, etc) already supporting implicit synchronization, may not be able to change to explict synchronization in a single switch. This extension allows synchronization to be controlled on a per-buffer basis, so explicit synchronization can be enabled for a complete pipeline which supports it, or implicit synchronization used otherwise.
Requires EGL 1.2
, KHR_image_base
and EXT_image_dma_buf_import
.
