From 4721cf1ecb949b37c98b6fce79163541711de2e5 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 3 Dec 1998 23:54:14 +0000 Subject: Patch from Emmanuel Raguet to add remote debug server and RPC support to RTEMS. Thanks. :) Email follows: Hello, For Xmas, here is the Remote Debugger on RTEMS ! Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux host : - one for RTEMS it self, - one for GDB-4.17. 1/ RTEMS patch -------------- This patch adds 2 libraries : - a simplified SUN RPC library - the Remote Debugger library The configuration command is the following : ../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386 --enable-rdbg The SUN RPC library is built only if networking is set. The RDBG library is built if networking and enable-rdbg are set. The function used to initialize the debugger is : rtems_rdbg_initialize (); A special function has been created to force a task to be in a "debug" state : enterRdbg(). The use of this function is not mandatory. 2/ GDB-4.17 patch ----------------- This patch create a new RTEMS target for GDB-4.17. The configuration command is the following : ./configure --enable-shared --target=i386RTEMS To connect to a target, use : target rtems [your_site_address] Then, attach the target using : attach 1 And... Debug ;) You can obtain the original GDB-4.17 on ftp://ftp.debian.org/debian/dists/stable/main/source/devel/gdb_4.17.orig.tar.gz This has been tested from a Debian 2.0.1 linux host. --- c/src/lib/include/rdbg/i386/rdbg_f.h | 53 ++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 c/src/lib/include/rdbg/i386/rdbg_f.h (limited to 'c/src/lib/include/rdbg/i386/rdbg_f.h') diff --git a/c/src/lib/include/rdbg/i386/rdbg_f.h b/c/src/lib/include/rdbg/i386/rdbg_f.h new file mode 100644 index 0000000000..3fd087f50a --- /dev/null +++ b/c/src/lib/include/rdbg/i386/rdbg_f.h @@ -0,0 +1,53 @@ +/* + ************************************************************************** + * + * Component = RDBG + * Module = rdbg_f.h + * + * Synopsis = Machine-dependent header file + * + ************************************************************************** + */ + +#ifndef RDBG_F_H +#define RDBG_F_H + +#include +#include + +#define EFLAGS_TF 0x00100 + +typedef struct Exception_context_struct { + struct Exception_context_struct *next; + struct Exception_context_struct *previous; + Objects_Id id; + Objects_Id semaphoreId; + CPU_Exception_frame *ctx; +} Exception_context; + +extern int PushExceptCtx (Objects_Id Id, + Objects_Id semId, + CPU_Exception_frame *ctx); +extern int PopExceptCtx (Objects_Id Id); +extern Exception_context *GetExceptCtx (Objects_Id Id); +extern int Single_Step (CPU_Exception_frame* ctx); +extern int CheckForSingleStep (CPU_Exception_frame* ctx); +extern void BreakPointExcHdl (CPU_Exception_frame *ctx); +extern void CtxToRegs (const CPU_Exception_frame*,xdr_regs*); +extern void RegsToCtx (const xdr_regs*,CPU_Exception_frame*); + +extern void enterRdbg (); +extern void get_ctx_thread (Thread_Control *thread, + CPU_Exception_frame* ctx); +extern void set_ctx_thread (Thread_Control *thread, + CPU_Exception_frame* ctx); + +void copyback_data_cache_and_invalidate_instr_cache(); + +extern int ExitForSingleStep; + + +#endif + + + -- cgit v1.2.3
