Struct WindowsKernelProcessorBlock 

Source 
pub struct WindowsKernelProcessorBlock<'a, Driver>
where
    Driver: VmiRead,
    Driver::Architecture: ArchAdapter<Driver>,
{ /* private fields */ }
Expand description

A Windows kernel processor control block (KPRCB).

The KPRCB is an opaque, per-processor structure embedded within the KPCR. While the KPCR (_KPCR) is the top-level per-processor region (anchored at gs:[0]), the KPRCB is its main body, holding the current/next/idle thread pointers, saved processor context, and scheduling state.

§Implementation Details

Corresponds to _KPRCB.

Implementations§

Source§

impl<'a, Driver> WindowsKernelProcessorBlock<'a, Driver>
where Driver: VmiRead, Driver::Architecture: ArchAdapter<Driver>,

Source

pub fn new(vmi: VmiState<'a, WindowsOs<Driver>>, va: Va) -> Self

Creates a new kernel processor control block.

Source

pub fn current_thread(&self) -> Result<WindowsThread<'a, Driver>, VmiError>

Returns the thread currently executing on this processor.

§Implementation Details

Corresponds to _KPRCB.CurrentThread.

Source

pub fn next_thread(&self) -> Result<Option<WindowsThread<'a, Driver>>, VmiError>

Returns the next thread scheduled to execute on this processor, if any.

§Implementation Details

Corresponds to _KPRCB.NextThread.

Source

pub fn idle_thread(&self) -> Result<WindowsThread<'a, Driver>, VmiError>

Returns the idle thread for this processor.

§Implementation Details

Corresponds to _KPRCB.IdleThread.

Source

pub fn processor_special_registers( &self, ) -> Result<impl WindowsSpecialRegisters, VmiError>

Returns the processor’s special registers.

§Implementation Details

Corresponds to _KPRCB.ProcessorState.SpecialRegisters.

Source

pub fn processor_context(&self) -> Result<impl WindowsContext, VmiError>

Returns the processor’s saved thread context.

On Windows 7 and later, reads the context via _KPRCB.Context pointer, which may reference a dynamically-allocated buffer for extended state (XSAVE/AVX). Falls back to the embedded ProcessorState.ContextFrame when the pointer is NULL (pre-Win7 or early boot).

§Implementation Details

Corresponds to _KPRCB.Context if non-NULL, otherwise _KPRCB.ProcessorState.ContextFrame.

Source

pub fn processor_context_frame(&self) -> Result<impl WindowsContext, VmiError>

Returns the processor’s saved thread context, read directly from the embedded ProcessorState.ContextFrame.

Useful when the _KPRCB.Context is unpopulated. Crash dumps from older Windows builds (Windows 7) leave _KPRCB.Context zero on the crashing CPU and write the registers into the embedded frame instead.

§Implementation Details

Corresponds to _KPRCB.ProcessorState.ContextFrame.
