Not all interrupt controllers enable IPIs by default as the Arm GIC specs make it an implementation defined option. As at least two hypervisors have also previously masked the IPIs on boot. As we already enable these IPIs on the non-boot CPUs it is expected this is a safe operation. Differential Revision: https://reviews.freebsd.org/D26975cgit

On arm64 we currently use a non-posted write for device memory, however we should move to use posted writes. This is expected to work on most hardware, however we will need to support a non-posted option for some broken hardware.

Summary: Since PCPU can live in a GPR for a while longer, let it, rather than re-getting it in yet another register. MFSPR is an expensive operation, 12 clock latency on POWER9, so the fewer operations we need, the better. Since the check is tightly coupled to the fetch, by reducing the number of fetch+check, we reduce the stalls, and improve the performance marginally. Buildworld was measured at a ~5-7% improvement on a single run. Reviewed By: nwhitehorn Differential Revision: https://reviews.freebsd.org/D30003cgit

It has to be zeroed before committing it to device. We do that by allocating it with M_ZERO, but there was no memory barrier or cache flush to ensure its sees it zeroed. This fixes MSIX on LS1028A SoC.

When sending an IPI, if a previous IPI is still pending delivery, native_lapic_ipi_vectored() waits for the previous IPI to be sent. We've seen a few inexplicable panics with the current timeout of 50 ms. Increase the timeout to 1 second and make it tunable. No hardware specification mentions a timeout in this case; I checked the Intel SDM, Intel MP spec, and Intel x2APIC spec. Linux and illumos wait forever. In Linux, see __default_send_IPI_shortcut() in arch/x86/kernel/apic/ipi.c. In illumos, see apic_send_ipi() in usr/src/uts/i86pc/io/pcplusmp/apic_common.c. However, misbehaving hardware could hang the system if we wait forever.

When VECTX is enabled as a kernel option and non-EFI loaders are built, many reads will fail due to the mis-match of whether LOADER_VERIEXEC_VECTX or not in readin.h.
