- V.7.0020.2004
-Thu , 24 Mar 2022
--------------------------------------------------------------------------------
- New Features
o sn2201: Add CPLD Minimal version for main and CPU board CPLDs
- Bug fixes
o sn2201: CPLD PN incorrect register address & shifted board components
o hw-mgmt: PSU thresholds sysfs changed in 5.10 to “read only” preventing modification (modification required due PSU HW bug)
o hw-mgmt: CPLD3 sysfs attribute missing after chip down/up flow
o hw-mgmt: sysfs attributes missing when hw-mgmt is restarted (stop/start) within systemd
- Known issues and limitations:
o This version disables system reset in thermal algorithm
o Kernel patch 4.9 #60 is available upstream from kernel 4.9.207 and
Kernel patch 4.19 #28 is available upstream from kernel 4.19.89.
- No need to apply these patches when working with these kernel versions
or above
o ethtool for QSFP-DD is working only in raw mode.
o SN4700 PSU (Murata) sensors PSU2 and PSU3 might be not available after insertion/removal.
o PSUs inventory read via PMBus require the following packages:
- i2c-tools_4.1-1_amd64.deb
- libi2c0_4.1-1_amd64.deb
o I2C Asic driver take up to 5 second to complete initialization. When
sending ADD even need to make sure to wait at list 5 second before
reset of ASIC.
o Systems SN2010, SN2100, SN2410, SN2700 and SN2740 (and their
"-B" variants) require the following flag in kernel cmdline:
"acpi_enforce_resources=lax acpi=noirq".
o Few bug fixes introduced in upstream kernel 4.19, whoever use older
v4.19 kernel then v4.19.58, should cherry pick the following commits:
- Fix wrong order in probing routine initialization:
d2d8f64012543898a0158b1fc5c07af3d41c89d8 (available in v4.19.49)
- Fix parent device in i2c-mux-reg device registration
c241f3fbfa1af86f572a92f2e4d708358e163806 (available in v4.19.58)
o Kernel patch 4.9 #37 is available upstream from kernel 4.9.197 and
Kernel patch 4.19 #09 is available upstream from kernel 4.19.79.
- No need to apply these patches when working with these kernel versions
or above
o This version requires FW version 29.2000.1886 or higher for spectrum-2
and 13.2000.1886 or higher for spectrum-1.
================================================================================
- V.7.0020.2000
-Tus , 15 Feb 2022

- New Features
o sn2201: add support for watchdog , pwr_dwn, pwr_cycle attributes
o sn2201: add thermal control definition table
o sn2201: add fan hot-plug event
o sn2201: add missing fan direction indication
o sn2201: add CPLD PN report

v4.19 kernel then v4.19.58, should cherry pick the following commits:
- Fix wrong order in probing routine initialization:
d2d8f64012543898a0158b1fc5c07af3d41c89d8 (available in v4.19.49)
- Fix parent device in i2c-mux-reg device registration
c241f3fbfa1af86f572a92f2e4d708358e163806 (available in v4.19.58)
o Kernel patch 4.9 #37 is available upstream from kernel 4.9.197 and
Kernel patch 4.19 #09 is available upstream from kernel 4.19.79.
- No need to apply these patches when working with these kernel versions
or above
o This version requires FW version 29.2000.1886 or higher for spectrum-2
and 13.2000.1886 or higher for spectrum-1.

*Kernel 4.19 - 0027-platform-x86-mlx-platform-Remove-PSU-EEPROM-configur.patch
- Known issues and limitations:
o Kernel patch 4.9 #60 is available upstream from kernel 4.9.207 and
Kernel patch 4.19 #28 is available upstream from kernel 4.19.89.
- No need to apply these patches when working with these kernel versions
or above
o ethtool for QSFP-DD is working only in raw mode.
o SN4700 PSU (Murata) sensors PSU2 and PSU3 might be not available after insertion/removal.
o PSUs inventory read via PMBus require the following packages:
- i2c-tools_4.1-1_amd64.deb
- libi2c0_4.1-1_amd64.deb
o I2C Asic driver take up to 5 second to complete initialization. When
sending ADD even need to make sure to wait at list 5 second before
reset of ASIC.
o Systems SN2010, SN2100, SN2410, SN2700 and SN2740 (and their
"-B" variants) require the following flag in kernel cmdline:
"acpi_enforce_resources=lax acpi=noirq".
