Hello,
Which is the maximum size supported for a custom BIOS image(eg.
coreboot-based)? I tried some 256K coreboot BIOS images and seemed to
work fine, but it blowed up with a 3MB image (which by the way works on
qemu just fine).
256K is the maximum with kvm. It can easily be increased, but we need a
small kernel change on Intel to store the real-mode TSS.
Hi Avi,
Thanks for your answer. What would be the upper bound up to which we can
extend it? May I somehow help in getting this done?
I don't know all the places; check the setup code in hw/pc.c. Also look
at the call to KVM_SET_TSS_ADDR and move it somewhere where it won't
clash (right now it's at 4GB-256K).

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
