[SeaBIOS] [PATCH 0/1] stacks: disable NMIs during state restore on call32_post()

Posted by Heitor Alves de Siqueira 4 months ago
Hi all,

We've had reports of users hitting KVM emulation failures in certain workloads
and were able to track down a missing NMI_DISABLE_BIT in call32_post() when
accessing CMOS ports. This patch disables NMIs on state restore, following other
accesses to CMOS_PORT_INDEX throughout the seabios code.
