This can degrade performance and cause Input Errors pps/bps spikes on Port extX/intX graphs. You can take some of the load off these cores by preventing non-critical subsystems from running on them. To do so: Specify isolation of the packet processor cores in the core options through the isolcpus=... and rcu_nocbs=... parameters. It is also recommended to add mitigations=off to disable core security patches. https://docs.mitigator.ru/v26.04/en/kb/amd/ Mon, 01 Jan 0001 00:00:00 +0000 https://docs.mitigator.ru/v26.04/en/kb/amd/ BIOS Setup for AMD EPYC and Ryzen Threadripper Platforms Mentioned only essential options that require attention. Option names may differ from listed. Refer to the BIOS configuration manual for your platform. Set one NUMA node per CPU. Use of multiple nodes per CPU is not recommended: NUMA Nodes Per Socket: NPS1 Enable Extended APIC. Recommended for server CPUs: Local APIC mode: x2APIC Virtualization support: SVM: Enabled IOMMU: Enabled Maximum CPU performance mode: https://docs.mitigator.ru/v26.04/en/kb/mellanox/ Mon, 01 Jan 0001 00:00:00 +0000 https://docs.mitigator.ru/v26.04/en/kb/mellanox/ System preparation Working with Mellanox (NVIDIA) cards requires the latest driver and device firmware NVIDIA MLNX_OFED. Using the provided link select the latest version of MLNX_OFED for the required distribution of the operating system in the table Current Versions of the Download section. Select the closest version of the OS if the required version is missing. Skip MLNX_OFED installation if the required OS is missing in the list. Tested to work on Debian 10+ and Ubuntu 20.
