Replace 'width' and 'height' in QemuDmaBuf with 'backing_widht' and 'backing_height' as these commonly indicate the size of the whole surface (e.g. guest's Xorg extended display). Then use 'width' and 'height' for sub region in there (e.g. guest's scanouts).

|
|
* Taken from glamor_egl.h from the Xorg xserver, which is MIT licensed
|
|
*
|
|
* Create an EGLDisplay from a native display type. This is a little quirky
|
|
* for a few reasons.
|
|
*
|
|
* 1: GetPlatformDisplayEXT and GetPlatformDisplay are the API you want to
|
|
* use, but have different function signatures in the third argument; this
|
|
* happens not to matter for us, at the moment, but it means epoxy won't alias
|
|
* them together.
|
|
*
|
|
* 2: epoxy 1.3 and earlier don't understand EGL client extensions, which
|
|
* means you can't call "eglGetPlatformDisplayEXT" directly, as the resolver
|
|
* will crash.
|
|
*
|
|
* 3: You can't tell whether you have EGL 1.5 at this point, because
|
|
* eglQueryString(EGL_VERSION) is a property of the display, which we don't
|
|
* have yet. So you have to query for extensions no matter what. Fortunately
|
|
* epoxy_has_egl_extension _does_ let you query for client extensions, so
|
|
* we don't have to write our own extension string parsing.
|
|
*
|
|
* 4. There is no EGL_KHR_platform_base to complement the EXT one, thus one
|
|
* needs to know EGL 1.5 is supported in order to use the eglGetPlatformDisplay
|
|
* function pointer.
|
|
* We can workaround this (circular dependency) by probing for the EGL 1.5
|
|
* platform extensions (EGL_KHR_platform_gbm and friends) yet it doesn't seem
|
|
* like mesa will be able to advertise these (even though it can do EGL 1.5).
