Why I did it Add platform support for Debian 12 (Bookworm) on Mellanox Platform How I did it Update hw-management to v7.0030.2008 Deprecate the sfp_count == module_count approach in favour of asic init completion Ref: Mellanox/hw-mgmt@bf4f593 Add xxd package to base image which is required by hw-management scripts Add the non-upstream flag into linux kernel cache options Update the thermalctl logic based on new sysfs attributes Fix the integrate-mlnx-hw-mgmt script to not populate the arm64 Kconfig How to verify it Build kernel and run platform tests Signed-off-by: Vivek Reddy <vkarri@nvidia.com> Co-authored-by: Junchao-Mellanox <junchao@nvidia.com> Co-authored-by: Junchao-Mellanox <57339448+Junchao-Mellanox@users.noreply.github.com>

Subject: [PATCH backport 6.1.42 71/85] UBUNTU: SAUCE: mlxbf-gige: Fix
|
|
intermittent no ip issue
|
|
|
|
BugLink: https://bugs.launchpad.net/bugs/2008833
|
|
|
|
During the reboot test, the OOB might not get an ip assigned.
|
|
This is due to a race condition between phy_startcall and the
|
|
RX DMA being enabled and depends on the amount of background
|
|
traffic received by the OOB. Enable the RX DMA after teh phy
|
|
is started.
