This set improves the error recovery flows in the QAT drivers and adds a mechanism to test it through an heartbeat simulator. When a QAT device reports either a fatal error, or an AER fatal error, or fails an heartbeat check, the PF driver sends an error notification to the VFs through PFVF comms and if `auto_reset` is enabled then the device goes through reset flows for error recovery. If SRIOV is enabled when an error is encountered, this is re-enabled after the reset cycle is done. Changed in v2: - Removed redundant default value in Kconfig - Removed ccflags define, use the CONFIG option directly in the code - Reworked the AER reset and recovery flow Damian Muszynski (2): crypto: qat - add heartbeat error simulator crypto: qat - add auto reset on error Furong Zhou (3): crypto: qat - add fatal error notify method crypto: qat - disable arbitration before reset crypto: qat - limit heartbeat notifications Mun Chun Yep (4): crypto: qat - update PFVF protocol for recovery crypto: qat - re-enable sriov after pf reset crypto: qat - add fatal error notification crypto: qat - improve aer error reset handling Documentation/ABI/testing/debugfs-driver-qat | 26 ++++ Documentation/ABI/testing/sysfs-driver-qat | 20 +++ drivers/crypto/intel/qat/Kconfig | 14 +++ drivers/crypto/intel/qat/qat_common/Makefile | 2 + .../intel/qat/qat_common/adf_accel_devices.h | 2 + drivers/crypto/intel/qat/qat_common/adf_aer.c | 116 +++++++++++++++++- .../intel/qat/qat_common/adf_cfg_strings.h | 1 + .../intel/qat/qat_common/adf_common_drv.h | 10 ++ .../intel/qat/qat_common/adf_heartbeat.c | 20 ++- .../intel/qat/qat_common/adf_heartbeat.h | 21 ++++ .../qat/qat_common/adf_heartbeat_dbgfs.c | 52 ++++++++ .../qat/qat_common/adf_heartbeat_inject.c | 76 ++++++++++++ .../intel/qat/qat_common/adf_hw_arbiter.c | 25 ++++ .../crypto/intel/qat/qat_common/adf_init.c | 12 ++ drivers/crypto/intel/qat/qat_common/adf_isr.c | 7 +- .../intel/qat/qat_common/adf_pfvf_msg.h | 7 +- .../intel/qat/qat_common/adf_pfvf_pf_msg.c | 64 +++++++++- .../intel/qat/qat_common/adf_pfvf_pf_msg.h | 21 ++++ .../intel/qat/qat_common/adf_pfvf_pf_proto.c | 8 ++ .../intel/qat/qat_common/adf_pfvf_vf_proto.c | 6 + .../crypto/intel/qat/qat_common/adf_sriov.c | 38 +++++- .../crypto/intel/qat/qat_common/adf_sysfs.c | 37 ++++++ 22 files changed, 571 insertions(+), 14 deletions(-) create mode 100644 drivers/crypto/intel/qat/qat_common/adf_heartbeat_inject.c -- 2.34.1
