- 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>

[ Upstream commit 804034c4ffc502795cea9b3867acb2ec7fad99ba ]
|
|
|
|
The devm_ioremap() function returns NULL on error, it doesn't return
|
|
error pointers. Also according to doc of device_property_read_u64_array,
|
|
values in info array are properties of device or NULL.
