Detailed Description

Concrete subclasses of this abstract class represent how the register values are transmitted on the wire.

Usually each architecture should define one subclass, but there can be more if there is more than one possible wire format. For example, ARM defines both AArch32GdbRegCache and AArch64GdbRegCache.

Member Function Documentation

data()

virtual char* BaseGdbRegCache::data ( ) const

pure virtual

Return the pointer to the raw bytes buffer containing the register values.

Each byte of this buffer is literally encoded as two hex digits in the g or G RSP packet.

Implemented in X86ISA::RemoteGDB::AMD64GdbRegCache, ArmISA::RemoteGDB::AArch64GdbRegCache, SparcISA::RemoteGDB::SPARC64GdbRegCache, X86ISA::RemoteGDB::X86GdbRegCache, ArmISA::RemoteGDB::AArch32GdbRegCache, MipsISA::RemoteGDB::MipsGdbRegCache, RiscvISA::RemoteGDB::RiscvGdbRegCache, SparcISA::RemoteGDB::SPARCGdbRegCache, and PowerISA::RemoteGDB::PowerGdbRegCache.

Referenced by BaseRemoteGDB::cmd_reg_r(), BaseRemoteGDB::cmd_reg_w(), and BaseRemoteGDB::TrapEvent::process().

getRegs()

virtual void BaseGdbRegCache::getRegs ( ThreadContext *  )

pure virtual

Fill the raw buffer from the registers in the ThreadContext.

Implemented in X86ISA::RemoteGDB::AMD64GdbRegCache, ArmISA::RemoteGDB::AArch64GdbRegCache, SparcISA::RemoteGDB::SPARC64GdbRegCache, X86ISA::RemoteGDB::X86GdbRegCache, ArmISA::RemoteGDB::AArch32GdbRegCache, MipsISA::RemoteGDB::MipsGdbRegCache, RiscvISA::RemoteGDB::RiscvGdbRegCache, SparcISA::RemoteGDB::SPARCGdbRegCache, and PowerISA::RemoteGDB::PowerGdbRegCache.

Referenced by BaseRemoteGDB::trap().

name()

virtual const std::string BaseGdbRegCache::name ( ) const

pure virtual

Return the name to use in places like DPRINTF.

Having each concrete superclass redefine this member is useful in situations where the class of the regCache can change on the fly.

Implemented in X86ISA::RemoteGDB::AMD64GdbRegCache, ArmISA::RemoteGDB::AArch64GdbRegCache, SparcISA::RemoteGDB::SPARC64GdbRegCache, X86ISA::RemoteGDB::X86GdbRegCache, ArmISA::RemoteGDB::AArch32GdbRegCache, MipsISA::RemoteGDB::MipsGdbRegCache, RiscvISA::RemoteGDB::RiscvGdbRegCache, SparcISA::RemoteGDB::SPARCGdbRegCache, and PowerISA::RemoteGDB::PowerGdbRegCache.

setRegs()

virtual void BaseGdbRegCache::setRegs ( ThreadContext *  ) const

pure virtual

Set the ThreadContext's registers from the values in the raw buffer.

Implemented in X86ISA::RemoteGDB::AMD64GdbRegCache, ArmISA::RemoteGDB::AArch64GdbRegCache, SparcISA::RemoteGDB::SPARC64GdbRegCache, X86ISA::RemoteGDB::X86GdbRegCache, ArmISA::RemoteGDB::AArch32GdbRegCache, MipsISA::RemoteGDB::MipsGdbRegCache, RiscvISA::RemoteGDB::RiscvGdbRegCache, SparcISA::RemoteGDB::SPARCGdbRegCache, and PowerISA::RemoteGDB::PowerGdbRegCache.

Referenced by BaseRemoteGDB::cmd_reg_w().

size()

virtual size_t BaseGdbRegCache::size ( ) const

pure virtual

Return the size of the raw buffer, in bytes (i.e., half of the number of digits in the g/G packet).

Implemented in X86ISA::RemoteGDB::AMD64GdbRegCache, ArmISA::RemoteGDB::AArch64GdbRegCache, SparcISA::RemoteGDB::SPARC64GdbRegCache, X86ISA::RemoteGDB::X86GdbRegCache, ArmISA::RemoteGDB::AArch32GdbRegCache, MipsISA::RemoteGDB::MipsGdbRegCache, RiscvISA::RemoteGDB::RiscvGdbRegCache, SparcISA::RemoteGDB::SPARCGdbRegCache, and PowerISA::RemoteGDB::PowerGdbRegCache.
