scsi: lpfc: Define size of debugfs entry for xri rebalancing

2025-09-17T02:19:59Z

To assist in debugging lpfc_xri_rebalancing driver parameter, a debugfs entry is used. The debugfs file operations for xri rebalancing have been previously implemented, but lack definition for its information buffer size. Similar to other pre-existing debugfs entry buffers, define LPFC_HDWQINFO_SIZE as 8192 bytes.

scsi: lpfc: Rework MIB Rx Monitor debug info logic

2022-09-01T03:39:58Z

The kernel test robot reported the following sparse warning: arch/arm64/include/asm/cmpxchg.h:88:1: sparse: sparse: cast truncates bits from constant value (369 becomes 69) On arm64, atomic_xchg only works on 8-bit byte fields. Thus, the macro usage of LPFC_RXMONITOR_TABLE_IN_USE can be unintentionally truncated leading to all logic involving the LPFC_RXMONITOR_TABLE_IN_USE macro to not work properly. Replace the Rx Table atomic_t indexing logic with a new lpfc_rx_info_monitor structure that holds a circular ring buffer. For locking semantics, a spinlock_t is used.

scsi: lpfc: Adjust CMF total bytes and rxmonitor

2021-12-07T03:35:37Z

Calculate any extra bytes needed to account for timer accuracy. If we are less than LPFC_CMF_INTERVAL, then calculate the adjustment needed for total to reflect a full LPFC_CMF_INTERVAL. Add additional info to rxmonitor, and adjust some log formatting.

scsi: lpfc: Make debugfs ktime stats generic for NVME and SCSI

2020-03-29T22:10:58Z

Currently driver ktime stats, measuring code paths, is NVME-specific. Convert the stats routines such that the code paths are generic, providing status for NVME and SCSI. Added ktime stat calls in SCSI queuecommand and cmpl routines.

scsi: lpfc: Fix erroneous cpu limit of 128 on I/O statistics

2020-03-29T22:10:48Z

The cpu io statistics were capped by a hard define limit of 128. This effectively was a max number of CPUs, not an actual CPU count, nor actual CPU numbers which can be even larger than both of those values. This made stats off/misleading and on large CPU count systems, wrong. Fix the stats so that all CPUs can have a stats struct. Fix the looping such that it loops by hdwq, finds CPUs that used the hdwq, and sum the stats, then display.
