From 4f608fbce54bf9e0a42c0e8584e59034dbf12665 Mon Sep 17 00:00:00 2001 From: Vishakha Channapattan Date: Sat, 9 Jan 2021 18:08:48 +0530 Subject: [PATCH] scsi: pm80xx: Log SATA IOMB completion status on failure Added a log message in SATA completion path to capture the status of failed command. If the status does not match any expected status, another message will be logged. On IO failure with known status, the log message will be: [ 1712.951735] pm80xx0:: mpi_sata_completion 2269: IO failed device_id 16385 status 0x1 tag XX If the firmware returns unexpected status, a message of the following format will be logged: [ 1712.951735] pm80xx0:: mpi_sata_completion XXXX: Unknown status device_id XXXXX status 0xX tag XX Link: https://lore.kernel.org/r/20210109123849.17098-8-Viswas.G@microchip.com Acked-by: Jack Wang Signed-off-by: Vishakha Channapattan Signed-off-by: Viswas G Signed-off-by: Ruksar Devadi Signed-off-by: Ashokkumar N Signed-off-by: Radha Ramachandran Signed-off-by: Martin K.
