BaseGdbRegCache()

gem5::BaseGdbRegCache::BaseGdbRegCache ( BaseRemoteGDB * g )

inlineprivate

Definition at line 134 of file remote_gdb.hh.

data()

char * gem5::RiscvISA::RemoteGDB::Riscv32GdbRegCache::data ( )

inlinevirtual

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.

Implements gem5::BaseGdbRegCache.

getRegs()

void gem5::RemoteGDB::Riscv32GdbRegCache::getRegs ( ThreadContext * )

virtual

Fill the raw buffer from the registers in the ThreadContext.

Implements gem5::BaseGdbRegCache.

name()

const std::string gem5::RiscvISA::RemoteGDB::Riscv32GdbRegCache::name ( ) const

inlinevirtual

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.

setRegs()

void gem5::RemoteGDB::Riscv32GdbRegCache::setRegs ( ThreadContext * ) const

virtual

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