* scsi: mpi3mr: Support for Segmented Hardware Trace bufferRanjan Kumar2025-02-031-0/+1
| | | | | | | | | | | | | | | | | Allocate segmented trace buffer if firmware advertises the capability in IOCfacts. Upon driver load, read the trace buffer size from driver page 1, calculate the required segments for trace buffer, and allocate segmented buffers. Each segment is 4096 bytes in size. While posting driver diagnostic buffer to firmware, advertise that trace buffer is segmented.

| | | | | | | | | | | Make driver use the timestamp update interval value provided by firmware in the driver page 1. If firmware fails to provide non-zero value, then the driver will fall back to the driver defined macro.

* scsi: mpi3mr: HDB allocation and posting for hardware and firmware buffersRanjan Kumar2024-06-261-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | To be able to debug controller problems it is beneficial to allocate and configure system/host memory buffers which can be used to capture hardware and firmware diagnostic information. Add functions required to allocate and post firmware and hardware diagnostic buffers to the controller and to set up automatic diagnostic capture triggers. Captures will be triggered under the following circumstances: 1. Firmware is in FAULT state. 2. Admin commands time out. 3. Controller reset caused due to I/O timeout Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202405151758.7xrJz6rp-lkp@intel.com/ Co-developed-by: Sathya Prakash <sathya.prakash@broadcom.com> Signed-off-by: Sathya Prakash <sathya.prakash@broadcom.com> Signed-off-by: Ranjan Kumar <ranjan.kumar@broadcom.com> Link: https://lore.kernel.org/r/20240626102646.14298-2-ranjan.kumar@broadcom.com Signed-off-by: Martin K.
