- Why I did it 1. Update Mellanox HW-MGMT package to newer version V.7.0030.1011 2. Replace the SONiC PMON Thermal control algorithm with the one inside the HW-MGMT package on all Nvidia platforms 3. Support Spectrum-4 systems - How I did it 1. Update the HW-MGMT package version number and submodule pointer 2. Remove the thermal control algorithm implementation from Mellanox platform API 3. Revise the patch to HW-MGMT package which will disable HW-MGMT from running on SIMX 4. Update the downstream kernel patch list Signed-off-by: Kebo Liu <kebol@nvidia.com>

Subject: [PATCH backport 5.10 130/182] devlink: introduce linecard info get
|
|
message
|
|
|
|
Allow the driver to provide per line card info get op to fill-up info,
|
|
similar to the "devlink dev info".
|
|
|
|
devlink: introduce line card devices support
|
|
|
|
Line card can contain a device. For example, this can be a gearbox with
|
|
flash. This flash could be updated. Provide the driver possibility to
|
|
attach such devices to a line card and expose those to user. Leverage
|
|
the existing devlink flash update mechanism and allow driver to pass a
|
|
custom "component name" string identifying the line card device to
|
|
flash.
|
