Subject: [PATCH 2/5] renderer/native: Try the gbm renderer before the
|
|
EGLDevice renderer
|
|
|
|
This switches the order of what renderer mode is tried first, so that
|
|
the gbm renderer mode is preferred on an NVIDIA driver where it is
|
|
supported.
|
|
|
|
We fall back to still try the EGLDevice renderer mode if the created gbm
|
|
renderer is not hardware accelerated.
|
|
|
|
The last fallback is still to use the gbm renderer, even if it is not
|
|
hardware accelerated, as this is needed when hardware acceleration isn't
|
|
available at all. The original reason for the old order was due to the
|
|
fact that a gbm renderer without hardware acceleration would succeed
|
|
even on NVIDIA driver that didn't support gbm.
|
