Created attachment 255599 [details] Problem description Dear all, We have found some difficulties in enabling SR-IOV on Intel's E810-CQDA2 network cards. It works fine for other vendors/models but not for E810 model. Intel's website confirms support of iavf and ice for FreeBSD. https://edc.intel.com/content/www/us/en/design/products/ethernet/adapters-and-devices-user-guide/install-freebsd-drivers/ FreeBSD official support for ice driver for "Intel(R) Ethernet Controller E810-C": https://man.freebsd.org/cgi/man.cgi?query=ice&apropos=0&sektion=0&manpath=FreeBSD+14.1-RELEASE+and+Ports&arch=default&format=html FreeBSD official support for iavf driver for "Intel(R) Ethernet Controller E810-C": https://man.freebsd.org/cgi/man.cgi?query=iavf&apropos=0&sektion=0&manpath=FreeBSD+14.1-RELEASE+and+Ports&arch=default&format=html It works for older cards like X710, but not for E810: https://freebsdfoundation.org/sr-iov-is-a-first-class-freebsd-feature/ Server has the official support for this network cards (listed in QVL). BIOS was updated to the latest version. I am enclosing a screen shot showing the problem. Regards Maciej.
It'd be useful to see "pciconf -lv" output from this system. It may be worth trying the net/intel-ice-kmod port, which is the official vendor driver, instead of the in-tree ice driver.
Please just use text instead of screenshots in the future if possible. Things that would be helpful to see to diagnose this further would be: 1) The output of dmesg with ice0 is loaded. 2) The output of 'pciconf -lc ice0'.
I'm afraid SR-IOV support in ice is not yet implemented. Neither in the in-tree, nor in the out-of-tree driver. We have already started working on that, but I can't provide you and ETA yet. For E800 adapters FreeBSD IAVF was tested with a Linux host, and that's the only officially supported use case at the moment.
This SR-IOV seems to be an underrated feature, but unfortunately, it is a vicious and not widely-tested feature. While trying quickly to enable it on the host running 14.2-STABLE I ended only with this: ixv0: <Intel(R) X520 82599 Virtual Function> at device 0.129 numa-domain 0 on pci5 ixv0: Using 2048 TX descriptors and 2048 RX descriptors ixv0: Using 1 RX queues 1 TX queues ixv0: Using MSI-X interrupts with 2 vectors ixv0: allocated for 1 queues ixv0: allocated for 1 rx queues ixv1: <Intel(R) X520 82599 Virtual Function> at device 0.131 numa-domain 0 on pci5 ixv1: Using 2048 TX descriptors and 2048 RX descriptors ixv1: Using 1 RX queues 1 TX queues ixv1: Using MSI-X interrupts with 2 vectors ixv1: allocated for 1 queues ixv1: allocated for 1 rx queues panic: APEI Fatal Hardware Error! cpuid = 10 time = 1733525039 KDB: stack backtrace: Uptime: 2m27s Not trying to hijack this PR, just posting FWIW.
