hyperv: Fix vmbus after the i386 4/4 split

2021-06-22T01:09:17Z

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.

2018-04-06T17:35:35Z

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 tree

2017-05-10T05:28:14Z

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@.
