2023-07-06VPP: T1797: Optimized memory allocation during startupzsdc
- changed memory requirement from total to available. This allows to start on systems with less total memory and protects from startup on systems with overloaded memory. - prevent startup if sysctl settings were not applied. This protects from situations when the system cannot allocate enough hugepages or apply other sysctl settings.
2023-07-03VPP: T1797: Added interfaces reinitializationzsdc
After an interface is added/removed from VPP, it will be reinitialized, which allows reconfiguring IP addresses on it. Also modified VPP load priority to start before interfaces, and avoid reconfiguration during boot.
2023-07-01T1797: VPP verify minimal installed memory and apply sysctlViacheslav Hletenko
Do not allow configure VPP if on the systems with low amount installed memory Add sysctl VPP parameters (hugepages, kernel.shmmax)
2023-06-29VPP: T1797: Optimized interfaces add/removezsdc
- added extra renaming operation to be sure that interface has the same name as before in the system after it was moved from VPP to kernel - added extra check after PCI device removal/adding - added check for proper `retval` for CPI calls where it is available - replaced empty return with an error in `_get_pci_address_by_interface()` because not resolved address will lead to inconsistency of the system later
2023-06-28VPP: T1797: Improved VPP supportzsdc
- added ability to add/remove interfaces without system reboot - added `attempts` and `interval` to the VPP API connection. This is helpful in case of high system load or when VPP was just started and API is not yet available. - added exceptions to API calls. This allows handling errors in communication with API properly in conf-mode scripts. - fixed PCI address search in VPP to match Linux kernel and ethtool style - fixed systemd daemons control - first reload, then restart - removed debug prints - removed `vm.nr_hugepages` configuration. It is not required now but increases RAM requirements a lot.
2023-06-27VPP: T1797: Improved PCI address searchzsdc
Use info from both ethtool and VPP to find PCI address for an interface.
2023-06-27VPP: T1797: Replaced CLI with APIzsdc
Replaced CLI commands with API calls. CLI commands still can be used via: ``` vpp_control = VPPControl() vpp_control.cli_cmd('command_here') ```
2023-06-27T1797: Add initial vpp configurationViacheslav Hletenko
Add initial configuration mode for VPP (PoC) set vpp cpu corelist-workers '2' set vpp cpu main-core '1' set vpp interface eth1 num-rx-desc '256' set vpp interface eth1 num-rx-queues '512' set vpp interface eth1 num-tx-desc '256' set vpp interface eth1 num-tx-queues '512' set vpp interface eth1 pci '0000:02:00.0' set vpp interface eth1 rx-mode 'polling' set vpp interface eth2 pci '0000:08:00.0' Limitation: - 'set vpp interface ethX pci auto' works only per first commit, then interface detached from default stack and creates tun interface 'ethX' to communicate with default stack. In this case we can't get PCI address via ethtool for 'tun' interfaces. But we can set pci address manualy. - Interface sync between default stack and VPP-DPDK stack After vpp change it doesn't trigger iproute2 for changes (should be written later) I.e. if we change something in vpp per each commit it restarts vpp.service it gets empty interface config as we don't configure vpp directly and it should be configured via iproute2 But then if we do any change on interface (for example description) it gets IP address, MTU, state, etc.
