CPSW Statistics

Introduction

The CPSW statistics module implements only the IOCTLs defined in the generic Enet Statistics API. There are no additional CPSW-specific IOCTLs.

The statistics structures are CPSW specific and may vary depending on the CPSW instance:

• CPSW_2G statistics:
  • Host port: CpswStats_HostPort_2g
  • MAC port: CpswStats_MacPort_2g
• CPSW_5G or CPSW9G statistics:
  • Host port: CpswStats_HostPort_Ng
  • MAC ports: CpswStats_MacPort_Ng

Interrupts:

• CPSW_STATS_PEND - CPSW half-rollover statistics interrupt. Peripheral driver must call CPSW_STATS_IOCTL_SYNC command to handle the interrupt which reads and decrements all statistics values, including the one(s) that had reached the half-rollover condition.
