[PATCH 0/4] Expose raw access to GuC log over debugfs

[Michal Wajdeczko]

We already provide the content of the GuC log in debugsfs, but it
is in a text format where each log dword is printed as hexadecimal
number, which does not scale well with large GuC log buffers.

Michal Wajdeczko (4):
  libfs: add simple_read_from_iomem()
  iosys-map: add iosys_map_read_from() helper
  drm/xe: Add wrapper for iosys_map_read_from
  drm/xe/guc: Expose raw access to GuC log over debugfs
