Subject: [PATCH openEuler-22.03-LTS 3/3] lspci: Decode VF 10-Bit Tag Requester
|
|
|
|
Decode VF 10-Bit Tag Requester Supported and Enable bit
|
|
in SR-IOV Capabilities Register.
|
|
|
|
Sample output:
|
|
IOVCap: Migration- 10BitTagReq- Interrupt Message Number: 000
|
|
IOVCtl: Enable+ Migration- Interrupt- MSE+ ARIHierarchy- 10BitTagReq-
