[PATCH] nodedev: Introduce new drm cap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



After 7f1bdec5fa0a0cd25 our nodedev driver is capable of
determining DRM devices (DRM stands for Direct Render Manager not
Digital rights management). There is still one bit missing
though: virConnectListAllNodeDevices() is capable of listing
either all devices or just those with specified capability. Well,
DRM capability is missing there.
