[Qemu-devel] [PATCH] Seabios - read e820 reserve from qemu_cfg

[Jes Sorensen]

Hi,

Right now KVM/QEMU relies on hard coded values in Seabios for the
reserved area for the TSS pages and the EPT page.

I'd like to suggest we change this to pass the value from QEMU via
qemu-cfg making it possible to move it around dynamically in the future.

Attached is a patch to Seabios for this, which defaults to the current
hard coded value if no value is provided by qemu-cfg. We can remove
the backwards compatibility later.

I'll post the QEMU patches for upstream QEMU and QEMU-KVM in a minute.

Comments most welcome!

Cheers,
Jes
