Subject: [PATCH] egl: use device dispatch if at least one vendor suceeds
|
||
|
|
|
||
|
|
Currently, in InitDeviceListInternal if any egl vendor fails to list
|
||
|
|
its devices for any reason the construction of the device list is
|
||
|
|
abandoned. That means that even if we have one vendor successfully
|
||
|
|
serving the application, the failure of another vendor library will
|
||
|
|
break any api calls related to egl devices.
|
||
|
|
|
||
|
|
Instead, if a vendor fails queryDevicesEXT the device mapping logic
|
||
|
|
should proceed as if it listed no devices. If the relevant device
|
||
|
|
belongs to the failed vendor then the dispatch will still fail with
|
||
|
|
EGL_BAD_DEVICE.
