Mlx5 devlink health fw reporters and sw reset support This series provides mlx5 firmware reset support and firmware devlink health reporters. 1) Add initial mlx5 kernel documentation and include devlink health reporters 2) Add CR-Space access and FW Crdump snapshot support via devlink region_snapshot 3) Issue software reset upon FW asserts 4) Add fw and fw_fatal devlink heath reporters to follow fw errors indication by dump and recover procedures and enable trigger these functionality by user. 4.1) fw reporter: The fw reporter implements diagnose and dump callbacks. It follows symptoms of fw error such as fw syndrome by triggering fw core dump and storing it and any other fw trace into the dump buffer. The fw reporter diagnose command can be triggered any time by the user to check current fw status. 4.2) fw_fatal repoter: The fw_fatal reporter implements dump and recover callbacks. It follows fatal errors indications by CR-space dump and recover flow. The CR-space dump uses vsc interface which is valid even if the FW command interface is not functional, which is the case in most FW fatal errors. The CR-space dump is stored as a memory region snapshot to ease read by address. The recover function runs recover flow which reloads the driver and triggers fw reset if needed. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEGhZs6bAKwk/OTgTpSD+KveBX+j4FAl0CsLgACgkQSD+KveBX +j7mFwf+MYvIbUO4mXyoZIezci1UCzt1vNAkUYPceE94O9fK68ItrwtwrstgIqqS 58Tgx//MXxPpe9k9NIWjeS3i8sjcb8fDoqkjOCj7KAchv0IhSUvYFRpBrUK+yTOW NIIXZzuCgIoR9a/hVlT/lhG+dm4MX2L5dWFtORLxMoO+ff3yiy4nNf9+Zdt0H7LT YCELWnKeIQCvdzJAxX7OyTh3eOfc/h7o1nOsU4VugBHxKxx4T+9A26d+cZeZH5Ox 3ikTCc01ivVHqcLydAy96HQu0MENSNYNpmyDxWum3oJGFFu6hBQTM2ueRmVWZfwH DRu+hhxONZROxxtpmP/ULmwYcLnBHg== =VhXt -----END PGP SIGNATURE----- Merge tag 'mlx5-updates-2019-06-13' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2019-06-13 Mlx5 devlink health fw reporters and sw reset support This series provides mlx5 firmware reset support and firmware devlink health reporters. 1) Add initial mlx5 kernel documentation and include devlink health reporters 2) Add CR-Space access and FW Crdump snapshot support via devlink region_snapshot 3) Issue software reset upon FW asserts 4) Add fw and fw_fatal devlink heath reporters to follow fw errors indication by dump and recover procedures and enable trigger these functionality by user. 4.1) fw reporter: The fw reporter implements diagnose and dump callbacks.
