[*] https://lore.kernel.org/all/6398dd6ed80fa_b05d1294fc@dwillia2-xfh.jf.intel.com.notmuch/ This code has been tested with a newer qemu which allows for more events to be returned at a time as well an additional QMP event and interrupt injection. Those patches will follow once they have been cleaned up. 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 To: Dan Williams Cc: Bjorn Helgaas Cc: Alison Schofield Cc: Vishal Verma Cc: Ira Weiny Cc: Davidlohr Bueso Cc: Jonathan Cameron Cc: Dave Jiang Cc: Ben Widawsky Cc: Steven Rostedt Cc: linux-kernel@vger.kernel.org Cc: linux-pci@vger.kernel.org Cc: linux-acpi@vger.kernel.org Cc: linux-cxl@vger.kernel.org Signed-off-by: Ira Weiny --- Changes in v6: - Dan: address the missed comments on V4 - Link to v5: https://lore.kernel.org/r/20221216-cxl-ev-log-v5-0-180c618ed5d1@intel.com --- Davidlohr Bueso (1): cxl/mem: Wire up event interrupts Ira Weiny (7): cxl/mem: Read, trace, and clear events on driver load cxl/mem: Trace General Media Event Record cxl/mem: Trace DRAM Event Record cxl/mem: Trace Memory Module Event Record cxl/test: Add generic mock events cxl/test: Add specific events cxl/test: Simulate event log overflow drivers/cxl/core/mbox.c | 187 +++++++++++++++++ drivers/cxl/core/trace.h | 479 ++++++++++++++++++++++++++++++++++++++++++ drivers/cxl/cxl.h | 16 ++ drivers/cxl/cxlmem.h | 173 +++++++++++++++ drivers/cxl/cxlpci.h | 6 + drivers/cxl/pci.c | 241 +++++++++++++++++++++ tools/testing/cxl/test/Kbuild | 2 +- tools/testing/cxl/test/mem.c | 352 +++++++++++++++++++++++++++++++ 8 files changed, 1455 insertions(+), 1 deletion(-) --- base-commit: 589c3357370a596ef7c99c00baca8ac799fce531 change-id: 20221216-cxl-ev-log-f06383197541 Best regards,
