2015-06-29Revert "Add device enumeration interface (v4)"Emil Velikov
This reverts commit fde4969176822fe54197b6baa78f8b0ef900baba. The commit adds an API that does not seem flexible enough to be used in current open-source projects. Additionally it adds a hidden dependency of libudev, which when used in mesa caused grief when combined with Steam('s runtime). Let's revert this for now and add a tweaked API later on that can be used in mesa/xserver.

2015-03-10drm: add drmGet(Primary|Render)DeviceNameFromFd functionsEmil Velikov
Currently most places assume reliable primary(master) <> render node mapping. Although this may work in some cases, it is not correct. Add a couple of helpers that hide the details and provide the name of the master or render device name, given an fd. The latter may belong to either the master, control or render node device. v2: - Rename Device and Primary to Master (aka the /dev/dri/cardX device). - Check for the file via readdir_r() rather than stat(). - Wrap the check into a single function. - Return NULL for non-linux platforms. v3: - Don't segfault if name is NULL. - Update function names, as suggested by Frank Binns. v4: - Update commit message to reflect the function name changes.

2015-02-11xf86drm: Unconditionally clear ioctl structsDaniel Vetter
We really have to do this to avoid surprises when extending the ABI later on. Especially when growing the structures. A bit overkill to update all the old legacy ioctl wrappers, but can't hurt really either.

2015-02-11drm: use drmIoctl everywhereDaniel Vetter
Well just core drm. All the other callers in there that still use direct calls to ioctl have some custom retry logic already, so should be good already. All the other offenders (tests, freedreno/kgsl, ...) don't really matter (e.g. kgsl is the blob library and so not a drm thing) or are again special exceptions with their own retry loops.
