Expand description
State object for a VCPU’s connection with the plugin process.
This is used by a VCPU thread to allow the plugin process to handle vmexits. Each method may
block indefinitely while the plugin process is handling requests. In order to cleanly shutdown
during these blocking calls, the connection
socket should be shutdown. This will end the
blocking calls,

pub fn new(

) -> PluginVcpu
Creates the plugin state and connection container for a VCPU thread.
sourcepub fn init(&self, vcpu: &Vcpu) -> SysResult<()>
pub fn init(&self, vcpu: &Vcpu) -> SysResult<()>
Tells the plugin process to initialize this VCPU.
This should be called for each VCPU before the first run of any of the VCPUs in the VM.
sourcepub fn pre_run(&self, vcpu: &Vcpu) -> SysResult<()>
pub fn pre_run(&self, vcpu: &Vcpu) -> SysResult<()>
The VCPU thread should call this before rerunning a VM in order to handle pending requests to this VCPU.

vcpu: &Vcpu

pub fn io_read(&self, addr: u64, data: &mut [u8], vcpu: &Vcpu) -> bool
Has the plugin process handle a IO port read.
sourcepub fn io_write(&self, addr: u64, data: &[u8], vcpu: &Vcpu) -> bool
pub fn io_write(&self, addr: u64, data: &[u8], vcpu: &Vcpu) -> bool
Has the plugin process handle a IO port write.
sourcepub fn mmio_read(&self, addr: u64, data: &mut [u8], vcpu: &Vcpu) -> bool
pub fn mmio_read(&self, addr: u64, data: &mut [u8], vcpu: &Vcpu) -> bool
Has the plugin process handle a MMIO read.
sourcepub fn mmio_write(&self, addr: u64, data: &[u8], vcpu: &Vcpu) -> bool
pub fn mmio_write(&self, addr: u64, data: &[u8], vcpu: &Vcpu) -> bool
Has the plugin process handle a MMIO write.
sourcepub fn hyperv_call(
&self,

data: &mut [u8],
vcpu: &Vcpu
) -> bool
pub fn hyperv_call(
&self,
input: u64,
params: [u64; 2],
data: &mut [u8],
vcpu: &Vcpu
) -> bool
Has the plugin process handle a hyper-v call.
sourcepub fn hyperv_synic(
&self,
msr: u32,
control: u64,
evt_page: u64,
msg_page: u64,
vcpu: &Vcpu
) -> bool
pub fn hyperv_synic(
&self,
msr: u32,
control: u64,
evt_page: u64,
msg_page: u64,
