Hyper-V: TLB flush enlightment using hypercall

2024-06-07T07:56:07Z

Currently FreeBSD uses IPI based TLB flushing for remote TLB flushing. Hyper-V allows hypercalls to flush local and remote TLB. The use of Hyper-V hypercalls gives significant performance improvement in TLB operations. This patch set during test has shown near to 40 percent TLB performance improvement. Also this patch adds rep hypercall implementation as well.

hyperv: Fix vmbus after the i386 4/4 split

2021-06-08T13:40:30Z

The vmbus ISR needs to live in a trampoline. Dynamically allocating a trampoline at driver initialization time poses some difficulties due to the fact that the KENTER macro assumes that the offset relative to tramp_idleptd is fixed at static link time. Another problem is that native_lapic_ipi_alloc() uses setidt(), which assumes a fixed trampoline offset. Rather than fight this, move the Hyper-V ISR to i386/exception.s. Add a new HYPERV kernel option to make this optional, and configure it by default on i386. This is sufficient to make use of vmbus(4) after the 4/4 split. Note that vmbus cannot be loaded dynamically and both the HYPERV option and device must be configured together. I think this is not too onerous a requirement, since vmbus(4) was previously non-functional.
