similar to: [PATCH] drm: serialize access to debugs_nodes.list

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. So, in order to

This is the next version of my patch series for teaching DRM how to automatically create debugfs nodes for drivers with MST topologies. This was originally intended just for nouveau, but has since been expanded to all DRM drivers. Changes since previous version: - Fix documentation error that got noticed by the kbuild bot in "drm/dp_mst: Pass entire connector to

This commit adds a function to dump a DRM GPU VA space and a macro for drivers to register the struct drm_info_list 'gpuvas' entry. Most likely, most drivers might maintain one DRM GPU VA space per struct drm_file, but there might also be drivers not having a fixed relation between DRM GPU VA spaces and a DRM core infrastructure, hence we need the indirection via the driver iterating

I made a little changes in this series: 1. merge the two last patches together 2. unify the private data interface with the drm debugfs one now it should be very obvious for a new dev on how to add new files to debugfs and how to get access to the nouveau structs Karol Herbst (5): debugfs: add infrastructure to add files with other fops than only read debugfs: rename functions to

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

Well I think we rejected that multiple times now. At least I find the symbolic permissions easier to read and I absolutely don't see any reason why we should only use one form. Christian.

There is currently a mixture of octal and symbolic permissions uses in files in drivers/gpu/drm and one file in drivers/gpu. There are ~270 existing octal uses and ~115 S_<FOO> uses. Convert all the S_<FOO> symbolic permissions to their octal equivalents as using octal and not symbolic permissions is preferred by many as more readable. see: https://lkml.org/lkml/2016/8/2/1945 Done

This adds some basic debug information about the internal nouveau state. making it slightly easier to determine which bo belongs to which vm address, as long as that program is still running.

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
