Why I did it
Requirements from Microsoft for fwutil update all state that all firmwares which support this upgrade flow must support upgrade within a single boot cycle. This conflicted with a number of Mellanox upgrade flows which have been revised to safely meet this requirement.
How I did it
Added --no-power-cycle flags to SSD and ONIE firmware scripts
Modified Platform API to call firmware upgrade flows with this new flag during fwutil update all
Added a script to our reboot plugin to handle installing firmwares in the correct order with prior to reboot
How to verify it
Populate platform_components.json with firmware for CPLD / BIOS / ONIE / SSD
Execute fwutil update all fw --boot cold
CPLD will burn / ONIE and BIOS images will stage / SSD will schedule for reboot
Reboot the switch
SSD will install / CPLD will refresh / switch will power cycle into ONIE
ONIE installer will upgrade ONIE and BIOS / switch will reboot back into SONiC
In SONiC run fwutil show status to check that all firmware upgrades were successful

- Why I did it
PDDF utils were python2 compliant and they needed to be migrated to Python3 (as per Bullseye)
PDDF common platform APIs file name changed as the name was already in use
Indentation issues
Dead/redundant code needed to be removed
- How I did it
Made files Python3 compliant
Indentation corrected
Redundant code removed
- How to verify it
AS7326 Accton platform uses PDDF. PDDF utils were run on this platform to verify.
- Why I did it
There were compilation errors and warnings like,
/usr/src/linux-headers-5.10.0-8-2-common/scripts/Makefile.build:69: You cannot use subdir-y/m to visit a module Makefile. Use obj-y/m instead.
fatal error: linux/platform_data/pca954x.h: No such file or directory
hwmon_device_register() is deprecated. Please convert the driver to use hwmon_device_register_with_info().
If PDDF kernel module compilation fails, the PDDF debian package was not detecting the break.
- How I did it
Modified the code with new kernel 5.10 APIs.
Modified the Makefiles to use 'obj-m' instead of 'subdir-y'
- How to verify it
PDDF is supported on Accton platform. Load the build on AS7326 setup and check the 'dmesg'

Why I did it
Adding platform support for centec v682-48y8c and v682-48x8c.
V682-48y8c switch has 48 SFP+ (1G/10G/25G) ports, 8 QSFP28 (40G/100G) ports on CENTEC TsingMa.MX.
V682-48y8c is different from V682-48y8c_d in that:
transceiver is managed by cpu smbus rather than TsingMa.MX i2c bus.
port led is managed by mcu inside TsingMa.MX.
fan, psu, sensors, leds are managed by cpu smbus other than the cpu board vendor's close sourse driver.
V682-48x8c switch has 48 SFP+ (1G/10G) ports, 8 QSFP28 (40G/100G) ports on CENTEC TsingMa.MX.
CPU used in v682-48y8c and v682-48x8c is Intel(R) Xeon(R) CPU D-1527.
How I did it
Modify related code in platform and device directory.
Upgrade centec sai to v1.9.
upgrade python to python3 and kernel version to 5.0 for V682-48y8c_d.
How to verify it

- Why I did it

SAI
1. Reclaim buffers for port which is admin down
2. Support for Spectrum-4 os Nvidia ASIC simulation
3. Support for SN2201
4. Fix host interface table entry, one channel per trap (fix sflow double registration)
5. 2 new queue counters - ecn marked packets + shared current occupancy
6. Fix storm policer unknown unicast
7. Add key/value for accuflow counters
8. Add MAC move
9. Add mirror congestion mode attribute
SDK
1. Under various circumstances, Ethernet ports falsely showed that InfiniBand cables were connected.
2. In SN4600C, at times, the link up time in both DAC and optics cables may, in the worst case, take up to 15 seconds.
3. Using SN4600C with copper or optics loopback cables in NRZ speeds, link may raise in long link up times
4. When ECMP has high amount of next-hops based on VLAN interfaces, in some rare cases, packets will get a wrong VLAN tag and will be dropped.
5. When connecting Spectrum devices with optical transceivers that support RXLOS, remote side port down might cause the switch firmware to get stuck and cause unexpected switch behavior.
6. Aggregation event is missing for WJH L2 drop reason 'Unicast egress port list is empty'.
7. Tying the SCL and SDA of the optical modules to 3.3V causes errors.
8. On SN4600, there was a delay of more than 10 seconds from the time a data packet is sent from CPU until it is transmitted through one of the switch ports.
9. While using SN4600C system with Finisar FTLC1157RGPL 100GbE CWDM4 modules, intermittent link flaps across multiple ports may be observed.
10. In Spectrum-2 and Spectrum-3 systems, link did not work in auto-negotiation when connected to Marvell PHY. KR mechanism has been enhanced to integrate with Marvell PHY.
11. The tunnel counter counts the drop packets now for Spectrum-2 and Spectrum-3 and consistent with Spectrum behavior and count the ECN dropped packets as well.
12. When connecting SN3800 to Cisco-9000, fast-linkup flow will fail and will rise in the normal flow.
13. Race condition in WJH library: when multiple threads load the LAG shared memory concurrently, the program may crash.
14. Add WJH L2 drop reason 'Unicast egress port list is empty' as a new drop reason.
15. Fixed a memory leak in sx_api_port_sflow_statistics_get API.
16. During initialization flow, the command interface that is used by the minimal driver and SDK caused the collision in the firmware since the same buffer is used in the firmware for the two interfaces.
17. Fix route issue on Kernel 5.10
- How I did it

Why I did it
Support zero buffer profiles
Add buffer profiles and pool definition for zero buffer profiles
Support applying zero profiles on INACTIVE PORTS
Enable dynamic buffer manager to load zero pools and profiles from a JSON file
Dependency: It depends on Azure/sonic-swss#1910 and submodule advancing PR once the former merged.
How I did it
Add buffer profiles and pool definition for zero buffer profiles
If the buffer model is static:
Apply normal buffer profiles to admin-up ports
Apply zero buffer profiles to admin-down ports
If the buffer model is dynamic:
Apply normal buffer profiles to all ports
buffer manager will take care when a port is shut down
Update buffers_config.j2 to support INACTIVE PORTS by extending the existing macros to generate the various buffer objects, including PGs, queues, ingress/egress profile lists
Originally, all the macros to generate the above buffer objects took active ports only as an argument
Now that buffer items need to be generated on inactive ports as well, an extra argument representing the inactive ports need to be added
To be backward compatible, a new series of macros are introduced to take both active and inactive ports as arguments
The original version (with active ports only) will be checked first. If it is not defined, then the extended version will be called
Only vendors who support zero profiles need to change their buffer templates
Enable buffer manager to load zero pools and profiles from a JSON file:
The JSON file is provided on a per-platform basis
It is copied from platform/<vendor> folder to /usr/share/sonic/temlates folder in compiling time and rendered when the swss container is being created.
To make code clean and reduce redundant code, extract common macros from buffer_defaults_t{0,1}.j2 of all SKUs to two common files:
One in Mellanox-SN2700-D48C8 for single ingress pool mode
The other in ACS-MSN2700 for double ingress pool mode
Those files of all other SKUs will be symbol link to the above files
Update sonic-cfggen test accordingly:
Adjust example output file of JSON template for unit test
Add unit test in for Mellanox's new buffer templates.
How to verify it
Regression test.
Unit test in sonic-cfggen
Run regression test and manually test.

- Why I did it
Support PSU voltage high/low thresholds and power max threshold
1. Add thresholds support for voltage and power.
2. As thresholds are not supported on all platforms, we need to check the capability first and fetch thresholds only if it is supported.
- How I did it
- How to verify it
Run regression test and manual test.

#### Why I did it
Mellanox builds were failing intermittently due to the `issue_version` file and MFT package not building correctly in the Azure pipeline environment (both of these packages were patched to build correctly with bullseye running on the host and buster running on the dockers)
#### How I did it
Fixed two problems:
1. BLDENV is not passed to the Makefiles so the references to this were replaced with correct logic
2. `issue_version` was not defined as a target for bullseye and as such was not cached. Altered the build such that it is defined as a target for bullseye (in the case of buster it builds the file, in the case of bullseye it copies from buster)
The previous PR fixing this was reverted as it is no longer necessary for a passing build and was not a long-term fix. https://github.com/Azure/sonic-buildimage/pull/9235
#### How to verify it
Build on AZP and verify success.
Remove the "4.19..." specific code to add "-unsigned" suffix and just do so for any linux version.
For the syseeprom API part, have the Arista syseeprom class inherit from a class that can populate db.

Why I did it
To include capabilities fields in platform.json of DellEMC S6000, S6100, Z9332f platforms.

This commit fixes/avoids the following errors encountered during the
marvell-armhf build for bullseye
- Fix Marvell prestera DMA driver build failure due to kallsyms_lookup_name()
no longer being exported by the updated bullseye kernel. This is a temporary
fix that will be replaced by a future version of the DMA driver.
- Update qemu-user-static version to align with the new glibc version included
in bullseye
- Skip systemd-sonic-generator unit tests to avoid test failures. Root cause is
still TBD
#### Why I did it
Fix the following build errors observed when building marvell-armhf for bullseye
1. Marvell Prestera DMA driver uses kernel API no longer exported
ERROR: modpost: "kallsyms_lookup_name" [/sonic/platform/marvell-armhf/prestera/mrvl-prestera/cpssEnabler/linuxNoKernelModule/drivers//mvDmaDrv.ko] undefined!
2. Old qemu-user-static version does not support semop() leading to following build failure

BRCM SAI missed implementing the SAI API "sai_query_stats_capability()" which is causing build issue.
The build issue is impacting PR(s) that need to use this API.
This PR is to stubbed BRCM SAI to add this SAI API and return not implemented so that it will fix build issue that it is causing.
No other functional changes were made.
The issu-version file for Mellanox is generated from the Mellanox SDK
libraries. The SDK is installed into a Buster docker container, but the
issu-version file goes onto the base OS, which is Bullseye. To work
around this, the issu-version build rules explicitly copies the
issu-version file to target/files/bullseye/ during the Buster build.
Because of our build infra, if caching is enabled and a cache is being
used, then for issu-version, since it is technically built as part of
Buster, then only target/files/buster/issu-version is saved into the
cache, and target/files/bullseye/issu-version isn't cached. If this
cache gets used, then target/files/bullseye/issu-version is missing, and
the final image build fails.
This is to work around the current build issue where Mellanox builds are
failing. This is so that issu-version is always "built", so that copy is
made into the bullseye directory.

Added support for Mellanox-SN2700 based SKU for docker-sonic-vs and to differentiate platform based on hw-sku rather than on fake_platform in VS.
Currently SAI VS library uses hwsku based SAI profile to differentiate and mock different platform implementations. The same functionality in swss is achieved using a fake_platform env variable.
Using a fake_platform has some drawbacks that the vs container appears to still use a different vendor hw-sku

- Why I did it
In case an app.ext requires a dependency syncd^1.0.0, the RPC version of syncd will not satisfy this constraint, since 1.0.0-rpc < 1.0.0. This is not correct to put 'rpc' as a prerelease identifier. Instead put 'rpc' as build metadata in the version: 1.0.0+rpc which satisfies the constraint ^1.0.0.
- How I did it
Changed the way how to version in RPC and DBG images are constructed.
- How to verify it
Install app.ext with syncd^1.0.0 dependency on a switch with RPC syncd docker.

Why I did it
Currently the mellanox platform API is validating the file extensions of firmware packages to be installed for basic sanity checking. However, ONIE packages do not have an extension and as such if there is a "." in the name it is taken to be an extension and then fails the sanity check.
How I did it
I removed the check which ensures that ONIE images don't have a file extension.
How to verify it

Why I did it
End goal: To have azure pipeline job to run multi-asic VS tests.
Intermediate goal: Require multi-asic KVM image so that the test can be run.
The difference between single asic and multi-asic KVM image is asic.conf file which has different NUM_ASIC values.
Idea behind the approach in this PR to attain the intermediate goal above:
Ease of building multi-asic KVM image so that any user or azure pipeline can use a simple make command to generate single or multi-asic KVM images as required.
Use a single onie installer image and multiple KVM images for single and multi-asic images.
Current scenario:
For VS platform, sonic-vs.bin is generated which is the onie installer image and sonic-vs.img.gz is generated which is the KVM iamge.
Scenario to be achieved:
sonic-vs.bin - which will include single asic platform, 4 asic platform and 6 asic platform.
sonic-vs.img.gz - single asic KVM image
sonic-4asic-vs.img.gz - 4 asic KVM image
sonic-6asic-vs.img.gz - 6 asic KVM image
In this PR, 2 new platforms are added for 4-asic and 6-asic VS.
How I did it
Create 4-asic and 6-asic device directories with the required files and hwsku files.
Add onie-recovery image information in vs platform.
How to verify it
After this PR change, no build change.
sonic-vs.bin onie installer image should include information of new multi-asic vs platforms.

* On Spectrum-2 systems and above, when using warm boot, setting max_bridge_num to a value greater than 1968 will cause an error and potential crash.
* Some Molex cables do not support speed after reboot

The start template script that this value is used in will determine what
network namespace to use, and will add --net=host if it needs to run in
the host namespace.
With Docker 20.10, if --net=host is specified twice in docker run, then
it errors out. Therefore, remove the explicit --net=host in the run
options setting and let the start template script specify it.

Why I did it
platform test suite failed for few API's in DellEMC Z9332f platform.
How I did it
Modified the API's to return the expected values in the script.
How to verify it
Run platform test suite after making the changes.
Why I did it
Update Makefile, so it does the following:
For a given platform, verify if platform/checkout/.ini exists and hence run the platform/checkout/template.j2. This allows platform code to be checked out during the 'make configure' stage.
How I did it
git clone git@github.com:Azure/sonic-buildimage.git
mkdir platform/cisco-8000
make init
make configure PLATFORM=cisco-8000
make all
This change is to add a gbsyncd container to accommodate the syncd process and the SAI libraries for the Credo gearbox chips.
How I did it
This container works similar to the existing Broadcom syncd container. Its main difference is that the SAI-related dynamic libraries are replaced by the ones for Credo gearbox chips, and the container only reacts to SAI events for the gearbox chips. The SAI libraries will be provided by the package libsai-credo_1.0_amd64.deb.
For the image build, the added container will be built and included in the Broadcom platform image, after $(LIBSAI_CREDO)_URL = is replaced to the correct value. For now, as $(LIBSAI_CREDO)_URL is empty, the container build is skipped in the image build.
After the container is included in the image, in the runtime, the container will begin with checking the existence of /usr/share/sonic/hwsku/gearbox_config.json; if that file is not provided, the container will exit by itself. Therefore, for platforms unrelated to the Credo chips, as long as they are not providing the file, they will not be affected by this change.
Why I did it
Added a check in determining CPU reset in fast-/warm-reboot in their respective platform plugin.

Why I did it
BIOS upgrade on rare cases cannot guarantee bus value remain the same on every BIOS release. Ignoring this field in order for pcied not to fail but still verify device id in a different way. The solution is future proof and will not require changes in code when new BIOS version is available
How I did it
Since bus is not a fixed value (it is determined by the bios version) we are ignoring this field, and instead checking if there is a device that match on all other fields that and in addition has a matching device id.
How to verify it
Verify no errors or failures in pcied on different BIOS version with the same code base.

- Why I did it
The methods get_model, get_serial, and get_revision have been implemented by reading relevant information from VPD and then recording the information into relevant fields.
However, there is no VPD data on platforms with fixed PSUs and relevant fields haven't been initialized, which causes the methods to throw exceptions. which in turn prevents psud from inserting fields into PSU table.
Eventually, this causes show platform psustatus doesn't output correct info.
- How I did it
Initialize those fields as N/A on systems with fixed PSUs.
- How to verify it

The Mellanox platform is required to support the fwutil auto-update feature defined here
This is to allow switches, when performing SONiC upgrades to choose whether to perform firmware upgrades that may interrupt the data plane through a cold boot.
How I did it
Two methods were added to the component implementations for mellanox.
In the base Component class we add a default function that chooses to skip the installation of any firmware unless the cold boot option is provided. This is because the Mellanox platform, by default, does not support installing firmware on ONIE, the CPLD, or the BIOS "on-the-fly".
In the ComponentSSD class we add a function that behaves similarly but uses the Mellanox specific SSD firmware upgrade tool to check if the current SSD supports being upgraded on the fly in order to decide whether to skip or perform the installation.
How to verify it
Unit tests are included with this PR. These test will run on build of target sonic-mellanox.bin
You may also perform fwutil auto-update ... commands after Azure/sonic-utilities#1242 is merged in.

#### Why I did it
- After [sonic-linux-kernel#177](https://github.com/Azure/sonic-linux-kernel/pull/177) changes, the I2C mux channels of Baseboard and Switchboard CPLDs are moved from i2c-4 and i2c-5 to i2c-36 and i2c-37 respectively.
- This caused QSFP driver initialization of i2c-36 to i2c-41 to fail causing the ports from Ethernet208 to Ethernet248 fail.
#### How I did it
- The fix to this problem is to change the order of QSFP driver initialization to I2C mux channels.
- Instead of the order i2c-10 to i2c-41, the order i2c-4 to i2c-35 is being utilized.
- Also, need to change the i2c-mux-channel number for Baseboard CPLD and switchboard CPLD in scripts to access them.
