# hiperiso host kernel configuration
|
|
# ================================
|
|
# Minimal x86_64 Linux kernel for the hiperiso hypervisor host.
|
|
#
|
|
# Goals:
|
|
# - KVM built-in (NOT module) so /dev/kvm is available with no module loader
|
|
# - USB mass-storage support (XHCI/EHCI/OHCI/UHCI) to read the USB stick
|
|
# - exFAT / NTFS3 / ext4 / FAT filesystems to read ISOs and write logs
|
|
# - Everything else stripped: no networking, no modules, no sound/wifi/DRM
|
|
# - Small enough to bzImage in ~5-8 MB
|
|
#
|
|
# Apply with: cp hiperiso_defconfig .config && make olddefconfig
|
|
