(Jonathan) - Reorder setting of access coordinate. (Jonathan) v3: - Break out ACPI_SRAT_DEVICE_HANDLE_SIZE define. Merged into ACPICA repo. - Break out code in hmat_parse_locality() to improve readability. (Jonathan) - Drop continue after setting gen target access data. (Jonathan) v2: - Add check for memory type for setting GENPORT access data. (Jonathan) - NODE_ACCESS_CLASS_GENPORT to NODE_ACCESS_CLASS_GENPORT_SINK - Change strncmp() to memcmp() for device handle compare Hi Dan, Rafale has provided his ack. You can take this series with the QTG series. This is the second set of ACPI changes that's part of the "cxl: Add support for QTG ID retrieval for CXL subsystem" [1]. It has dependency on the patch [2] that was sent to you and GregKH and Greg has ack'd. But it's independent of the first set of ACPI changes [3]. The series adds support to store the device handle from the SRAT Generic Port Affinity Structure in correlation with a proximity domain. And later on the HMAT is parsed and the performance data is stored associated with the proximity domain. A helper function is added to allow the CXL driver to retrieve the performance data that matches with the device handle later on. The full series of CXL code is at this git repo [4] for usage reference.
