+- Bug fixes
+
+ o #3608425 SN2201: hw-management chipup error on alligator
+ o #3584693 MSN4600C: There are issues in hw-mgmt sensor conf
+
+ o For detailed patch list: Please view: https://github.com/Mellanox/hw-mgmt/blob/V.7.0020.4400/recipes-kernel/linux/Patch_Status_Table.txt
+
+ - Known issues and limitations:
+ o Systems like sn2700 which contain delta 460 PSU may have "Error getting sensor data: dps460/#25: Can't read"
+ which is a temporary inaccessibility of certain alarm attributes read from the PSU
+ 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.
