VM GPU passthrough resizable BAR support in 6.1 kernel
GPU resizable BAR support is coming in Linux kernel 6.1. It'd be great to support this natively in Unraid, somehow in the VM GUI or a setting or at least a documented script or how-to.
Looks like I figured it out, I had left out the steps to add the extra lines to my Win11 VM, which enabled 64GB ReBAR support.
So looks like the checklist to enable this:
- Host BIOS Enable ReBAR support
- Host BIOS Enable 4G Decoding
- Enable & Boot Custom Kernel syslinux configuration (near beginning of this thread)
- Boot Unraid in UEFI Mode
- VM must use UEFI BIOS
- VM must have the top line of XML from <domain type='kvm'> to:
