[PATCH v2 0/8] PF: Support for adverse events notifications

[Michal Wajdeczko]

The GuC firmware monitors VF's activity and notifies the PF driver
once any configured threshold related to such activity is exceeded.

To avoid having to rewrite a lot of code for each threshold and to
be prepared for any new GuC threshold additions, where possible,
use macros to generate threshold specific code.

v1: https://patchwork.freedesktop.org/series/133236/#rev1
v2: improve readability of macros (Piotr)
    fix kernel-doc (Piotr, CI.hooks)
    add explicit asserts (Piotr)

Michal Wajdeczko (8):
  drm/xe/guc: Add more KLV helper macros
  drm/xe/guc: Introduce GuC KLV thresholds set
  drm/xe/guc: Add support for threshold KLVs in to_string() helper
  drm/xe/pf: Introduce functions to configure VF thresholds
  drm/xe/pf: Allow configuration of VF thresholds over debugfs
  drm/xe/guc: Add GUC2PF_ADVERSE_EVENT to ABI
  drm/xe/pf: Track adverse events notifications from GuC
  drm/xe/pf: Expose PF monitor details via debugfs
