* 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.

* 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@.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The feature enables us to pass through physical PCIe devices to FreeBSD VM running on Hyper-V (Windows Server 2016) to get near-native performance with low CPU utilization. The patch implements a PCI bridge driver to support the feature: 1) The pcib driver talks to the host to discover device(s) and presents the device(s) to FreeBSD's pci driver via PCI configuration space (note: to access the configuration space, we don't use the standard I/O port 0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V, which is very similar to the 0xCF8/CFC method). 2) The pcib driver allocates resources for the device(s) and initialize the related BARs, when the device driver's attach method is invoked; 3) The pcib driver talks to the host to create MSI/MSI-X interrupt remapping between the guest and the host; 4) The pcib driver supports device hot add/remove.

* hyperv/vss: Add driver and tools for VSSSepherosa Ziehau2016-11-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VSS stands for "Volume Shadow Copy Service". Unlike virtual machine snapshot, it only takes snapshot for the virtual disks, so both filesystem and applications have to aware of it, and cooperate the whole VSS process. This driver exposes two device files to the userland: /dev/hv_fsvss_dev Normally userland programs should _not_ mess with this device file. It is currently used by the hv_vss_daemon(8), which freezes and thaws the filesystem. NOTE: currently only UFS is supported, if the system mounts _any_ other filesystems, the hv_vss_daemon(8) will veto the VSS process. If hv_vss_daemon(8) was disabled, then this device file must be opened, and proper ioctls must be issued to keep the VSS working. /dev/hv_appvss_dev Userland application can opened this device file to receive the VSS freeze notification, hold the VSS for a while (mainly to flush application data to filesystem), release the VSS process, and receive the VSS thaw notification i.e. applications can run again. The VSS will still work, even if this device file is not opened. However, only filesystem consistency is promised, if this device file is not opened or is not operated properly. hv_vss_daemon(8) is started by devd(8) by default. It can be disabled by editting /etc/devd/hyperv.conf.
