Re: [PATCH] x86/Viridian: don't mark IRQ vectors as pending when vLAPIC is disabled
On 21/11/2022 12:13, Jan Beulich wrote:
In software-disabled state an LAPIC does not accept any interrupt
requests and hence no IRR bit would newly become set while in this
state. As a result it is also wrong for us to mark Viridian IPI or timer
vectors as having a pending request when the vLAPIC is in this state.
Such interrupts are simply lost.
Introduce a local variable in send_ipi() to help readability.
