- Why I did it
This is for the eventual support of multiple architectures for the mellanox platform.
- How I did it
Change the location of the binaries in Switch-SDK-drivers so that the path specifies the target architecture in addition to the target distribution that the debians are built for.
This is the most straightforward way to separate binaries built against different architectures and selectively target them for installation in the mellanox SONiC image.
- How to verify it
Build SONiC for mellanox and verify it compiles successfully.
Why I did it
Support to use symbol links in platform folder to reduce the image size.
The current solution is to copy each lazy installation targets (xxx.deb files) to each of the folders in the platform folder. The size will keep growing when more and more packages added in the platform folder. For cisco-8000 as an example, the size will be up to 2G, while most of them are duplicate packages in the platform folder.
How I did it
Create a new folder in platform/common, all the deb packages are copied to the folder, any other folders where use the packages are the symbol links to the common folder.
Why platform.tar?
We have implemented a patch for it, see #10775, but the problem is the the onie use really old unzip version, cannot support the symbol links.
The current solution is similar to the PR 10775, but make the platform folder into a tar package, which can be supported by onie. During the installation, the package.tar will be extracted to the original folder and removed.

This PR aims to fix an issue (#10088) by enhancing the script memory_checker.
Specifically, if container is not created successfully during device is booted/rebooted, then memory_checker do not need check its memory usage.
How I did it
In the script memory_checker, a function is added to get names of running containers. If the specified container name is not in current running container list, then this script will exit without checking its memory usage.
How to verify it
I tested on a lab device by following the steps:
Stops telemetry container with command sudo systemctl stop telemetry.service
Removes telemetry container with command docker rm telemetry
Checks whether the script memory_checker ran by Monit will generate the syslog message saying it will exit without checking memory usage of telemetry.
Issue fixed: when performing a warm-reboot or fast-reboot from 201811 or 201911 to 202012 the kernel command line contains duplicate information. This issue is related to a change that was made to make 202012 boot0 file more futureproof.
A cold reboot brings everything back into a clean slate though not always desirable.
Changes done:
Added some logic to properly detect the end of the Aboot cmdline when cmdline-aboot-end delimiter is not set (clean case)
Added some logic to regenerate the Aboot cmdline when cmdline-aboot-end is set but duplicate parameters exists before (dirty case). Reorganized some code to handle duplicate parameter handling in the allowlist.

Configure different DSCP_TO_TC_MAP between uplink and downlink on T1 switch in dual ToR scenario
On T1 uplink, both DSCP 2/6 will be mapped to TC 1 for the purpose of avoiding such traffic occupying lossless buffers.
On T1 downlink, they will be mapped to TC 2/6 respectively. (unchanged)
- How I did it
For vendors who want to configure different DSCP_TO_TC_MAP between uplinks and downlinks on T1, they should
Define generate_dscp_to_tc_map macro in SKU's qos.json.j2 file
Define map AZURE for downlink and AZURE_UPLINK for uplink
Define jinja2 variable different_dscp_to_tc_map as True

Why I did it
- To reduce rc.local script execution time.
- Time consumption of rc.local script is around 22 seconds in S6100.
How I did it
- Moving platform-modules-s6100.service and s6100-lpc-monitor.service asynchronous to rc.local script.
How to verify it
- Load the image with the changes and the time consumption of rc.local script reduced from 22 seconds(approx.) to 14 seconds(approx.) during warm-/fast-reboot upgrades.
- sonic-mgmt test results.
Why I did it
Support Mellanox-SN4600C-C64 as T1 switch in dual-ToR scenario
1. Support additional queue and PG in buffer templates, including both traditional and dynamic model
2. Support mapping DSCP 2/6 to lossless traffic in the QoS template.
3. Add macros to generate additional lossless PG in the dynamic model
4. Adjust the order in which the generic/dedicated (with additional lossless queues) macros are checked and called to generate buffer tables in common template buffers_config.j2
- Buffer tables are rendered via using macros.
- Both generic and dedicated macros are defined on our platform. Currently, the generic one is called as long as it is defined, which causes the generic one always being called on our platform. To avoid it, the dedicated macrio is checked and called first and then the generic ones.
5. Support MAP_PFC_PRIORITY_TO_PRIORITY_GROUP on ports with additional lossless queues.
On Mellanox-SN4600C-C64, buffer configuration for t1 is calculated as:
40 * 100G downlink ports with 4 lossless PGs/queues, 1 lossy PG, and 3 lossy queues
16 * 100G uplink ports with 2 lossless PGs/queues, 1 lossy PG, and 5 lossy queues

How I did it
How to verify it
- Why I did it
Recent change to delay PMON service in case of fast/warm reboot introduce an issue when restarting only SWSS service after fast/warm reboot for Nvidia platform.
Since the timer is triggered only when the system boot, in a scenario when the system is after a fast/warm reboot and the user restart SWSS service, as part of syncd.sh script, PMON service will stop but the timer will not start again.
- How I did it
On syncd.sh script, in case of fast/warm indication, check if pmon.timer is running.
If it is running it means we are at the first boot and continue normally.
If it is not running, meaning the service was restarted, start the timer to keep the system behavior consistent.
- How to verify it
Run fast/warm reboot.
service swss restart.
Observe PMON service starting.
Why I did it
