Add support for the 1bit ECC error recovery by abnormal interrupt reporting and adjusts the structure of the abnormal interrupt handler. The following is the outline of each patch: (1)#1~#4: Cleanup and bugfix for the abnormal interrupt handler. (2)#5: Support for the 1bit ECC error recovery. Changes since v2: * Optimize the logic of the exit of fmea_recover_others() in #5. * v2 Link: https://patchwork.kernel.org/project/linux-rdma/cover/20220713092630.1657-1-liangwenpeng@xxxxxxxxxx/ Changes since v1: * Embed ecc_work into structure hns_roce_dev, no longer dynamically allocated in #5. * Add the const keyword to the string array that does not change in #5. * v1 Link: https://patchwork.kernel.org/project/linux-rdma/cover/20220624110845.48184-1-liangwenpeng@xxxxxxxxxx/ Haoyue Xu (5): RDMA/hns: Remove unused abnormal interrupt of type RAS RDMA/hns: Fix the wrong type of return value of the interrupt handler RDMA/hns: Fix incorrect clearing of interrupt status register RDMA/hns: Refactor the abnormal interrupt handler function RDMA/hns: Recover 1bit-ECC error of RAM on chip drivers/infiniband/hw/hns/hns_roce_device.h | 1 + drivers/infiniband/hw/hns/hns_roce_hw_v2.c | 248 +++++++++++++++++--- drivers/infiniband/hw/hns/hns_roce_hw_v2.h | 13 +- 3 files changed, 227 insertions(+), 35 deletions(-) -- 2.33.0
