* Hyper-V: TLB flush enlightment using hypercallSouradeep Chakrabarti2024-06-071-2/+2
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | This is the last part for ARM64 Hyper-V enablement. This includes commone files and make file changes to enable the ARM64 FreeBSD guest on Hyper-V. With this patch, it should be able to build the ARM64 image and install it on Hyper-V.

* hyperv: Fix vmbus after the i386 4/4 splitMark Johnston2021-06-081-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Move most of the contents of opt_compat.h to opt_global.h.Brooks Davis2018-04-061-1/+1
| | | | | | | | | | | | | | | | | | | | | opt_compat.h is mentioned in nearly 180 files. In-progress network driver compabibility improvements may add over 100 more so this is closer to "just about everywhere" than "only some files" per the guidance in sys/conf/options. Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h is created on all architectures. Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the set of compiled files.

* hyperv/vmbus: Reorganize vmbus device treeSepherosa Ziehau2017-05-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | For GEN1 Hyper-V, vmbus is attached to pcib0, which contains the resources for PCI passthrough and SR-IOV. There is no acpi_syscontainer0 on GEN1 Hyper-V. For GEN2 Hyper-V, vmbus is attached to acpi_syscontainer0, which contains the resources for PCI passthrough and SR-IOV. There is no pcib0 on GEN2 Hyper-V. The ACPI VMBUS device now only holds its _CRS, which is empty as of this commit; its existence is mainly for upward compatibility. Device tree structure is suggested by jhb@.
