During platform deinitialization, dell_ich is not removed properly and when we do initialize s6100 platform, ICH driver sysfs attributes are not attached. Because of this, get_transceiver_change_event returns error and this leads xcvrd to crash.
- What I did
Added Daemon to Log LPC bus degradation in Intel C2000 processor. Intel Rangeley C2000 processors with revision less than or equal to 2 have issue where LPC bus degrades over time in some processors. To identify the problem and to notify the issue, a daemon has been added which will log on encountering the issue.
- How I did it
Added a daemon which validates the CPLD scratch(0x102) and SMF scratch(0x202) registers by writing and reading values on regular polling intervals (300 seconds). If there is a discrepancy between read and write, a critical log will be thrown.
- How to verify it
The infra is verify by simulating the issue where between write and read, the value in register is modified and the log appearance is checked.
- Description for the changelog
Added Daemon to identify LPC bus degradation issue and notify using syslog in Dell S6100 and Z9100 platforms. This daemon will only run on processors with revision less than or equal to 2.
* [submodule] update sonic-linux-kernel (#2985)
* Fix many version strings
* Update minor version
* Update arista-drivers submodule (#9)
* Rebuild SDK on new kernel (#10)
dell_ich module fails to load sometimes due to the failure of pci_get_drvdata().
This function is responsible for fetching INTEL PCI related memory handle in kernel. This is implemented in lpc_ich kernel module.
Due to race in addition/deletion of kernel modules, sometimes lpc_ich loads after dell_ich.
Because of this behaviour dell_ich module fails to load.
Fixed by addding dependency between modules.
Removed i2c_mux_gpio module from blacklist entry as it is not the original root case of this issue.
