Template: librumpdev-pci/hugepages
Type: boolean
Default: true
Description: Automatically configure hugepages?
Rump drivers for PCI devices need spare hugepages in order to obtain
access to DMA-safe (i.e. physically-contigous) memory. A detailed
explanation is available at:
.
https://github.com/rumpkernel/wiki/wiki/Howto%3A-Accessing-PCI-devices-from-userspace
.
If you plan on using Rump drivers for PCI devices, you can either
configure them manually or have this script automatically configure
them for you.
Template: librumpdev-pci/nr_hugepages
Type: string
Default: 64
Description: Number of hugepages available to userland:
From this menu you can define the number of hugepages that you wish
to make available to userland applications (a reasonable default value
has been selected for you).
.
Note: If you see errors like:
.
"iwn0: could not allocate TX ring DMA memory"
.
when trying to use Rump PCI drivers, it's possible that you need to set
a large value here.
