US 2014/0372795 A1 · IMPLEMENTING DISTRIBUTED DEBUG DATA COLLECTION AND ANALYSIS FOR A SHARED ADAPTER IN A VIRTUALIZED SYSTEM

Abstract

A method, system and computer program product are provided for implementing distributed debug data collection and analysis for a hardware I/O adapter, such as, a Single Root Input/Output Virtualization (SRIOV) adapter in a virtualized system. A predetermined event triggers a base error collection sequence. Adapter driver data is collected and virtual function (VF) device drivers are locked out responsive to triggering the base error collection sequence. Adapter debug data is collected and the adapter is reinitialized including an indication to VF drivers if VF error data is to be collected. The virtual function (VF) device drivers are unlocked allowing the VF device drivers to commence recovery of a respective virtual function (VF).

Dependent claims

A method for distributed debug data collection and analysis for an input/output (I/O) adapter in a computer system comprising:

triggering a base error collection sequence responsive to a predetermined triggering event;
collecting adapter driver data and locking out virtual function (VF) device drivers responsive to triggering the base error collection sequence;
collecting adapter debug data and reinitializing the adapter including providing an indication to said VF device drivers if VF error data is to be collected;
and
unlocking the virtual function (VF) device drivers, allowing the VF device drivers to commence recovery of a respective virtual function (VF).
