Alan Adamson 9f079dda14 nvme: allow passthru cmd error logging ... Commit d7ac8dca93 ("nvme: quiet user passthrough command errors") disabled error logging for user passthrough commands. This commit adds the ability to opt-in to passthrough admin error logging. IO commands initiated as passthrough will always be logged. The logging output for passthrough commands (Admin and IO) has been changed to include CDWXX fields. nvme0n1: Read(0x2), LBA Out of Range (sct 0x0 / sc 0x80) DNR cdw10=0x0 cdw11=0x1 cdw12=0x70000 cdw13=0x0 cdw14=0x0 cdw15=0x0 Add a helper function nvme_log_err_passthru() which allows us to log error for passthru commands by decoding cdw10-cdw15 values of nvme command. Add a new sysfs attr passthru_err_log_enabled that allows user to conditionally enable passthrough command logging for either passthrough Admin commands sent to the controller or passthrough IO commands sent to a namespace. By default, passthrough error logging is disabled. To enable passthrough admin error logging: echo 1 > /sys/class/nvme/nvme0/passthru_err_log_enabled To disable passthrough admin error logging: echo 0 > /sys/class/nvme/nvme0/passthru_err_log_enabled To enable passthrough io error logging: echo 1 > /sys/class/nvme/nvme0/nvme0n1/passthru_err_log_enabled To disable passthrough io error logging: echo 0 > /sys/class/nvme/nvme0/nvme0n1/passthru_err_log_enabled Signed-off-by: Alan Adamson <alan.adamson@oracle.com> Signed-off-by: Chaitanya Kulkarni <kch@nvidia.com> Reviewed-by: Chaitanya Kulkarni <kch@nvidia.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Keith Busch <kbusch@kernel.org>		2024-02-01 07:44:53 -08:00
