[PATCH v2 0/1] s390x: css: pong, channel subsystem test device

Posted by Pierre Morel 4 years, 5 months ago

This patch series presents a device to test the channel subsystem.

Currently it only does the following:
- answer to WRITE requests by incrementing an integer stored as
  string in the data of a PONG_WRITE CCW command.
- send back the same buffer, with the incremented integer when
  receiving a PONG_READ CCW command.
- defines a Control Unit property.
