[PATCH v3 0/6] features provisioning fixes and mlx5_vdpa support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This patchset is pre-requisite to export and provision device
config attributes and features for vdpa live migration, in a way
backward and forward compatibility can be retained. The follow up
work [1] will need to be built around the new feature provisioning
uAPI, with which it's easier to formalize migration compatibility
support at the driver level.


[1] [PATCH v3 0/4] vDPA: initial config export via "vdpa dev show"

v2 -> v3:
  - fix incorrect reference of local variable in future patch
  - prohibit per-device bitmask macro from exposure in uapi header
  - add fixes tag
v1 -> v2:
  - include specific attribute info to error message 
  - move conditional feature presence in mlx5_vdpa config space
    to a separate patch
  - remove redundant check

Si-Wei Liu (6):
  vdpa: fix improper error message when adding vdpa dev
  vdpa: conditionally read STATUS in config space
  vdpa: validate provisioned device features against specified attribute
  vdpa: validate device feature provisioning against supported class
  vdpa/mlx5: conditionally show MTU and STATUS in config space
  vdpa/mlx5: support device features provisioning
