| |
CXL devices have multiple event logs which can be queried for CXL event records.
Add event log processing and cxl-test infrastructure. In addition to cxl-test, this code has been tested with the qemu patches posted here:
https://lore.kernel.org/all/20221221-ira-cxl-events-2022-11-17-v2-0-2ce2ecc06219@intel.com/
The series is now in 3 parts:
1) Base functionality including interrupts 2) Tracing specific events (Dynamic Capacity Event Record is defered) 3) cxl-test infrastructure for basic tests
