PVSCSI(4)             DragonFly 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_req_call_threshold
     setting to nonzero value enables the request call threshold
     functionality.  TODO.  Default is 1.

DESCRIPTION
     The pvscsi driver provides support for the VMware Paravirtual SCSI
     Controller (PVSCSI) in virtual machines by VMware.
