PVSCSI(4) Kernel Interfaces Manual PVSCSI(4) NAME pvscsi -- VMware Paravirtual SCSI Controller SYNOPSIS To compile this driver into the kernel, place the following line in your kernel configuration file: device pci device scbus device pvscsi Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): pvscsi_load="YES" The following tunables are settable from the loader(8): hw.pvscsi.request_ring_pages controls how many pages are allocated for the device request ring. A non- positive value will cause the driver to choose the value based on device capabilities. A non-zero value will use that many number of pages up to a maximum of 32. The default setting is 0. hw.pvscsi.max_queue_depth controls the queue size for the adapter. A non-positive value will cause the driver to choose the value based on number of request ring pages. A non-zero value will set the queue size up to a maximum allowed by the number of request ring pages. Default is 0. hw.pvscsi.use_msg setting to nonzero value enables the use of the PVSCSI message queue allowing for disk hot-add and remove without manual rescan needed. Default is 1. hw.pvscsi.use_msi setting to nonzero value enables the use of MSI interrupts. Default is 1. hw.pvscsi.use_msix setting to nonzero value enables the use of MSI-X interrupts. Default is 1. hw.pvscsi.use_req_call_threshold setting to nonzero value enables the request call threshold functionality. TODO. Default is 1.
