Member Function Documentation

GetState()

virtual TraceIntelPTGetStateResponse lldb_private::process_linux::IntelPTProcessTrace::GetState ( )

pure virtual

Construct a minimal jLLDBTraceGetState response for this process trace.

Implemented in lldb_private::process_linux::IntelPTMultiCoreTrace, and lldb_private::process_linux::IntelPTPerThreadProcessTrace.

ProcessDidStop()

virtual void lldb_private::process_linux::IntelPTProcessTrace::ProcessDidStop ( )

inlinevirtual

Reimplemented in lldb_private::process_linux::IntelPTMultiCoreTrace.

Definition at line 25 of file IntelPTProcessTrace.h.

ProcessWillResume()

virtual void lldb_private::process_linux::IntelPTProcessTrace::ProcessWillResume ( )

inlinevirtual

Reimplemented in lldb_private::process_linux::IntelPTMultiCoreTrace.

Definition at line 27 of file IntelPTProcessTrace.h.

TraceStart()

virtual llvm::Error lldb_private::process_linux::IntelPTProcessTrace::TraceStart ( lldb::tid_t  tid )

pure virtual

Start tracing the thread given by its tid.

Returns

An error if the operation failed.

Implemented in lldb_private::process_linux::IntelPTMultiCoreTrace, and lldb_private::process_linux::IntelPTPerThreadProcessTrace.

TracesThread()

virtual bool lldb_private::process_linux::IntelPTProcessTrace::TracesThread ( lldb::tid_t  tid ) const

pure virtual

Implemented in lldb_private::process_linux::IntelPTMultiCoreTrace, and lldb_private::process_linux::IntelPTPerThreadProcessTrace.

TraceStop()

virtual llvm::Error lldb_private::process_linux::IntelPTProcessTrace::TraceStop ( lldb::tid_t  tid )

pure virtual

Stop tracing the thread given by its tid.

Returns

An error if the given thread is not being traced or tracing couldn't be stopped.

Implemented in lldb_private::process_linux::IntelPTMultiCoreTrace, and lldb_private::process_linux::IntelPTPerThreadProcessTrace.

TryGetBinaryData()

virtual llvm::Expected< std::optional< std::vector< uint8_t > > > lldb_private::process_linux::IntelPTProcessTrace::TryGetBinaryData ( const TraceGetBinaryDataRequest &  request )

pure virtual

Returns

std::nullopt if this instance doesn't support the requested data, an llvm::Error if this isntance supports it but fails at fetching it, and Error::success() otherwise.

Implemented in lldb_private::process_linux::IntelPTMultiCoreTrace, and lldb_private::process_linux::IntelPTPerThreadProcessTrace.
