The controllers managed by mpi3mr driver requires system memory to
save hardware and firmware diagnostic information, this patch set
enhances the drivers to provide host memory to the controller for
diagnostic information. This patch set also provides driver changes
to push kernel messages into the diagnostic buffers reserved for the
driver, so that the information will be available as part of debug
data fetched from the controller. In addition, support for
configuring automatic diagnostic information is added in the driver.
Change since v1:
- Fixed test robot build warnings
Ranjan Kumar (6):
mpi3mr: HDB allocation and posting for hardware and Firmware buffers
mpi3mr: Driver buffer allocation and posting
mpi3mr: Dump driver and dmesg logs into driver diag buffer
mpi3mr: Trigger support
mpi3mr: Ioctl support for HDB
mpi3mr: Update driver version to 8.9.1.0.50

This patch adds functions require to allocate and post
firmware and hardware diagnostic buffers to the controller
and to setup automatic diagnostic capture triggers

[-- Attachment #1: Type: text/plain, Size: 6913 bytes --]
This patch adds support for collecting the kernel messages based
on the driver buffer capture level set in the module parameter
and copy the pertinent information to the driver diagnostic buffer
posted to the controller. The buffer capture and copy will be
executed when the driver detected the controller in the fault state.
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202405151829.zc0uNh0u-lkp@intel.com/

This patch adds functions to process automatic diag triggers and
if a condition defined in the triggers is met the driver will call
appropriate controller functions to save the diagnostic information.
