Nouveau, when configured with debugfs, creates debugfs files for every channel, so structure holding list of files needs to be protected from simultaneous changes by multiple threads. Without this patch it's possible to hit kernel oops in drm_debugfs_remove_files just by running a couple of xterms with looped glxinfo.

Currently all debugfs related initialization for the DRM core happens in drm_debugfs_init(), which is called when registering the minor device. While this works fine for features such as atomic modesetting and GEM, this doesn't work at all for resources like DP MST topology managers which can potentially be created both before and after the minor device has been registered.

Hi, Here is my patch queue I accumulated over quite a long time. Patches 1-6 are bugfixes, and rest is mostly RFC. Comments are welcome. Best regards, Maxim Levitsky

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Version 2 of the patch set doesn't contain functional changes. I'm reposting due to the rebasing onto the debugfs patches. v2: * updated for debugfs support * fixed typos in comments Thomas Zimmermann (4): drm/vram: Move VRAM
