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):

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

This hooks up the DRM helpers for dumping information on the current status of each MST topology from nouveau's perspective to debugfs files, similar to what i915 does (albeit, i915 labels their debugfs node for this as i915_dp_mst_info).

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

this series makes use of the load counters we can use to get information about the current load of the gpu. This series includes the needed pmu bits and a debugfs interface to read them out. Currently the values are between 0 and 255, because it is much easier to implement it this way on the pmu. Karol Herbst (4): subdev/pmu/fuc: add gk104 pmu/fuc: add macros for pdaemon pwr counters

these are usually used for dynamic reclocking on gt215 and newer The counters are used to get the load of the core, memory, video and pcie loads currently I expose the loads through a debugfs "current_load" file, but I want to move that to nvif and just add a wrapper around that in debugfs for convenience Anyway there are still some issues I would like to discuss: 1. currently the
