similar to: [PATCH v2 0/4] drm/dp_mst: Add DP MST debugfs nodes for all drivers

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

Originally I was just going to be adding dp_mst_status for nouveau until Daniel Stone pointed out that we should probably just make this so it's magically added for every DRM driver that's using the DRM DP MST helpers. So, let's do that! Signed-off-by: Lyude Paul <lyude at redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst at linux.intel.com> Cc: Daniel Stone <daniel

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.

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.

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, This is the fifth version of this patch series. With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen relies on it to set the logical ID and the GIC, it won''t be possible to use Xen with this use case. This patch series is divided in 3 parts: - Patch 1: prepare Xen

Overall idea: Detect lockups by watching for timeouts (vm flush / fence), return -EIOs, handle them at ioctl level, reset the GPU and repeat last ioctl. GPU reset is done by doing suspend / resume cycle with few tweaks: - CPU-only bo eviction - ignoring vm flush / fence timeouts - shortening waits Signed-off-by: Marcin Slusarz <marcin.slusarz at gmail.com> ---

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

This is a small patch series that adds a strap_peek file into our debugfs, and sets the size of the vbios.rom debugfs file so that nvbios can easily be used to parse the vbios even on systems where the normal BIOS retrieval methods (for example, laptops that need ACPI to access the vbios for the nvidia GPU) won't work. This should make it a little easier to collect vbioses. Lyude Paul (2):

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

As there is no need to check for the return value of debugfs_create_file and drm_debugfs_create_files, remove unnecessary checks and error handling in nouveau_drm_debugfs_init.
