# DPDK requires hugepages. I reserved 4 * 1GB hugepages on the host. ENABLE INTEL IOMMU and Hugepages

I use the `vfio-pci` driver for DPDK, so SR-IOV should be enabled on the host. Other drivers like `igb_uio` or `uio_pci_generic` don't need this IOMMU. For more information about Linux drivers for DPDK, see https://doc.dpdk.org/guides/linux_gsg/linux_drivers.html.

DPDK requires hugepages. I reserved 4 * 1GB hugepages on the host.
|
|
|
|
- Make sure IOMMU and SR-IOV are enabled in BIOS.
|
|
- Edit /etc/default/grub, on the line GRUB_CMDLINE_LINUX_DEFAULT, add `intel_iommu=on iommu=pt default_hugepagesz=1G hugepagesz=1G hugepages=4`.
|
|
- Apply the change by running `grub-mkconfig -o /boot/grub/grub.cfg`.
|
|
|
|
update-grub
|
|
update-initramfs -u
|
|
|
|
## Auto-load `vfio-pci` on boot
|
|
|
|
Run `echo vfio-pci >> /etc/modules-load.d/modules.conf`.
|
|
|
|
## Reboot and verification
|
|
|
|
- After rebooting, check if IOMMU is functioning by reading driver message:
|
|
```sh
|
|
dmesg | grep -e DMAR -e IOMMU
|
|
```
|
|
|
|
- Check if hugepages are reserved:
|
|
|
|
```sh
|
|
apt install libhugetlbfs-bin
|
|
hugeadm --explain
|
|
```
