Ming Lei 8a05aa4ce3 mtip32xx: avoid to read HOST_CAP from HW in .queue_rq() ... It is observed reading the register from HW takes a bit long, for example in my box, the following difference of 'perf report --no-children fio ...' can be seen when running I/O: 1) V4.12 without patch + 9.28% fio [mtip32xx] [k] mtip_irq_handler + 8.48% fio [mtip32xx] [k] mtip_init_cmd_header 2) V4.12 with the following patch + 9.14% fio [mtip32xx] [k] mtip_irq_handler ...... + 1.14% fio [mtip32xx] [k] mtip_init_cmd_header IOPS can be increased by ~5% with this patch too.
