[Qemu-discuss] Can not relocate APIC registers address from 0xFEE00000 to self-defined physical addr
Wed, 10 Jul 2019 16:02:31 +0800 (CST)
I wrote a Small OS (based on linux0.11) support SMP, and it can run well on
Now i want to migrate it to Qemu, i found that when i use wrmsr command to
relocate the APIC regsiters addr to a new physical address,
it can not work, i can not initial APIC timer to trigger timer interrupt by the
new physical addr just i relocate,
but when use rdmsr to get APIC base addr, it has been changed to the new
physical address, So it's strange.
In SMP env, if can not relocate APIC registers addr for each processor with
different addr, it will result in conflict.
So, i want to know qemu4.0 whether support remaping APIC base address by wrmsr
if support, please tell me how to remap APIC base addr for each processor.
