Implementations

impl Dr7

pub const EMPTY: usize = 1_024usize

Empty Dr7 has bit 10 always set.

pub const GD_BIT: usize = 13usize

Bit that controls debug-register protection.

pub const RTM_BIT: usize = 11usize

Bit that controls debugging of RTM transactional regions.

pub const GE_BIT: usize = 9usize

Bit that controls global exact breakpoints.

pub const LE_BIT: usize = 8usize

Bit that controls local exact breakpoints.

pub fn configure_bp( &mut self, bp: Breakpoint, bc: BreakCondition, bs: BreakSize, )

Configures a breakpoint condition bc and size bs for the associated breakpoint bp.

Note

This should be called before enable_bp.

pub fn enable_bp(&mut self, bp: Breakpoint, global: bool)

Enables the breakpoint condition for the associated breakpoint.

Arguments

• bp - The breakpoint to enable.
• global - If true, the breakpoint is global (e.g., never reset on task switches). If false, the CPU resets the flag (disables bp) on task switch.

pub fn disable_bp(&mut self, bp: Breakpoint, global: bool)

Disables the breakpoint condition for the associated breakpoint.

• bp: The breakpoint to disable.
• global: If true, the global breakpoint bit is unset (e.g., never reset on task switches). If false, the local breakpoint bit is unset.

pub fn enable_exact_local_bp(&mut self)

Local exact breakpoint enable.

This flag causes the processor to detect the exact instruction that caused a data breakpoint condition. This feature is not supported in the P6 family processors, later IA-32 processors, and Intel 64 processors.

For backward and forward compatibility with other Intel processors, Intel recommends that the LE flag be set to 1 if exact breakpoints are required.

pub fn enable_exact_global_bp(&mut self)

Global exact breakpoint enable.

This flag causes the processor to detect the exact instruction that caused a data breakpoint condition. This feature is not supported in the P6 family processors, later IA-32 processors, and Intel 64 processors.

For backward and forward compatibility with other Intel processors, Intel recommends that the GE flag be set to 1 if exact breakpoints are required.

pub fn enable_rtm(&mut self)

Enables advanced debugging of RTM transactional regions.

Note

This advanced debugging is enabled only if IA32_DEBUGCTL.RTM is also set.

pub fn enable_general_detect(&mut self)

Enables debug-register protection, which causes a debug exception to be generated prior to any MOV instruction that accesses a debug register.

Trait Implementations

impl Clone for Dr7

fn clone(&self) -> Dr7

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Dr7

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Dr7

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Dr7

fn eq(&self, other: &Dr7) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
