Description Mark Wielaard 2024-11-27 13:09:31 UTC 
There are more than 100 DRM_IOCTLs, or more than 400 when including all the driver specific variants.

We are supporting most generic DRM_IOCTLs that create new file descriptors for --track-fds=yes.
See https://bugs.kde.org/show_bug.cgi?id=492422
But checking usage of (existing) fds is not generally done.

What is missing is at least support for:

DMA_BUF_IOCTL_EXPORT_SYNC_FILE
DMA_BUF_IOCTL_IMPORT_SYNC_FILE

DRM_IOCTL_PRIME_FD_TO_HANDLE
DRM_IOCTL_SYNCOBJ_FD_TO_HANDLE
DRM_IOCTL_SYNCOBJ_EVENTFD
