- 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

- Why I did it
Facilitate Automatic integration of new hw-mgmt version into SONiC.
Inputs to the Script:
MLNX_HW_MANAGEMENT_VERSION Eg: 7.0040.5202
CREATE_BRANCH: (y|n) Creates a branch instead of a commit (optional, default: n)
BRANCH_SONIC: Only relevant when CREATE_BRANCH is y. Default: master.
Note: These should be provided through SONIC_OVERRIDE_BUILD_VARS parameter
Output:
Script creates a commit (in each of sonic-buildimage, sonic-linux-kernel) with all the changes required for upgrading the hw-management version to a version provided by MLNX_HW_MANAGEMENT_VERSION
Brief Summary of the changes made:
MLNX_HW_MANAGEMENT_VERSION flag in the hw-management.mk file
hw-mgmt submodule is updated to the corresponding version
Updates are made to non-upstream-patches/patches and series.patch file
series, kconfig-inclusion and kconfig-exclusion files can be updated in the sonic-linux-kernel repo
sonic-linux-kernel/patches folder is updated with the corresponding upstream patches
Based on the inputs, there could be a branch seen in the local for each of the repo's. Branch is named as <branch>_<parent_commit>_integrate_<hw_mgmt_version>
- How I did it
Added a new make target which can be invoked by calling make integrate-mlnx-hw-mgmt

Changes made will be summarized under sonic-buildimage/integrate-mlnx-hw-mgmt_user.out file. Debugging and troubleshooting output is written to sonic-buildimage/integrate-mlnx-hw-mgmt.log files
User output file & stdout file:
log_files.tar.gz
Limitations:
Assumes the changes would only work for amd64
Assumes the non-upstream patches in mellanox only belong to hw-mgmt
- How to verify it
Build the Kernel
Signed-off-by: Vivek Reddy Karri <vkarri@nvidia.com>
- Why I did it
Currently, non upstream patches are applied only after upstream patches.
Depends on sonic-net/sonic-linux-kernel#313. Can be merged in any order, preferably together
- What I did it
Non upstream Patches that reside in the sonic repo will not be saved in a tar file bur rather in a folder pointed out by EXTERNAL_KERNEL_PATCH_LOC. This is to make changes to the non upstream patches easily traceable.
The build variable name is also updated to INCLUDE_EXTERNAL_PATCHES
Files/folders expected under EXTERNAL_KERNEL_PATCH_LOC
EXTERNAL_KERNEL_PATCH_LOC/
├──── patches/
├── 0001-xxxxx.patch
├── 0001-yyyyyyyy.patch
├── .............
├──── series.patch
series.patch should contain a diff that is applied on the sonic-linux-kernel/patch/series file. The diff should include all the non-upstream patches.
How to verify it
Build the Kernel and verified if all the patches are applied properly
Signed-off-by: Vivek Reddy Karri <vkarri@nvidia.com>
- Why I did it
Add non-upstream kernel patches for the Nvidia platforms
These patches are not yet upstream but needed for new technology.
A flow to upstream them is in progress and once they will be approved they will be moved officially to sonic-linux-kernel.
Till then to include them in the build (not must) the build option INCLUDE_EXTERNAL_PATCH_TAR=y should be included
- How I did it
Zip all the patches in to a tar.gz tarball.
- How to verify it
Manually test
