This is an enhancement request.
Is there any plan to backport to Spinhawk the QDIO/QETH enhancements present in Hyperion ?
The current QETH code in hyperion (including QDIO interrupt control in channel code) is functional at least for Layer 2 support (tested under z/VM 6.3, in VSWITCH mode or direct z/VM TCPIP control mode as well as Linux running directly under hercules and under z/VM)
The code in hyperion channel code includes QDIO Signaling, QDIO interrupt support and QDIO Thin Interrupt support (Thin Interrupt means an interrupt does not require a TSCH to be cleared).
I have however no idea the amount of work it would take to port that particular portion without importing anything else that might have been changed in the I/O support code.
