Using timer-override.conf, we modify the fstrim.timer service.
For armhf, Nokia-7215 platform, we modify fstrim.timer to run daily
instead of weekly. This is required because the size of the SSD on
this platform is 16GB, which on average is nearly 10 times smaller than
most other sonic platforms. With smaller disk and the ever increasing
level of logging done by sonic, this change is required to prevent
the SSD from entering a read-only state due to inadequate free blocks.
Why I did it
High CPU utilization by entropy.py
How I did it
Remove entropy script as it does not work anymore and is no longer needed for bullseye(202205).
In Buster(202012) the max available poolsize (entropy_avail) for entropy is 4096 and our entropy.py script was based on this value. With the change in kernel to bullseye on 202205 this entropy poolsize was changed to 256 which also causes our script to fail.
This script was initially added to provide SW assistance to improve the system entropy value available early on in the Sonic boot sequence on buster.
On bullseye (Linux kernel 5.10) this is no longer needed as this feature has been improved.
How to verify it
run "top" command to check CPU usage.
- Why I did it
Enable platform API tests to run successfully by providing required test infrastructure files along with supporting changes.
- How I did it
Added platform.json along with supporting changes.
- Addition of pcie.yaml supporting pcied
- Addition of Real fan drawer support vs Virtual
- Removal of python2 wheel with support in place for python3
- supporting changes platform api tests
- Improve random number generation during early Sonic initialization by providing SW updates to Linux entropy value.
- Improve handling of platform In-Band management port
This commit provides the following updates to the Nokia ixs7215 platform
1. The Marvell Armada-38x SOC requires SW assistance to improve the system
entropy value available early on in the Sonic boot sequence.
2. The Nokia ixs7215 platform does not have a dedicated Out-Of-Band (OOB) mgmt
port and thus requires additional logic to optionally support configuring
front panel port 48 as an In-Band mgmt port. This commit provides additional
logic to manage and maintain the operation of this In-Band mgmt port.
