- * Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- * Module name: remcom.c $
- * Revision: 1.34 $
- * Date: 91/03/09 12:29:49 $
- * Contributor: Lake Stevens Instrument Division$
- *
- * Description: low level support for gdb debugger. $
- *
- * Considerations: only works on target hardware $
- *
- * Written by: Glenn Engel $
- * ModuleState: Experimental $
- *
- * NOTES: See Below $
- *
- * Modified for SPARC by Stu Grossman, Cygnus Support.
- *
- * This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- * To enable debugger support, two things need to happen. One, a
- * call to set_debug_traps() is necessary in order to allow any breakpoints
- * or error conditions to be properly intercepted and reported to gdb.
- * Two, a breakpoint needs to be generated to begin communication. This
- * is most easily accomplished by a call to breakpoint(). Breakpoint()
- * simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- * The following gdb commands are supported:
- *
- * command function Return value
- *
- * g return the value of the CPU registers hex data or ENN
- * G set the value of the CPU registers OK or ENN
- *
- * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
- * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
- *
- * c Resume at current address SNN ( signal NN)
- * cAA..AA Continue at address AA..AA SNN
- *
- * s Step one instruction SNN
- * sAA..AA Step one instruction from AA..AA SNN
- *
- * k kill
- *
- * ? What was the last sigval ? SNN (signal NN)
- *
- * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
- * baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum. A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer. '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host: Reply:
- * $m0,10#2a +$00010203040506070809101112131415#42

- * XXX This raises the question, whether we can do the same on

- * XXX answer is yes. We stick fork_kpsr in UREG_G0 and
- * XXX fork_kwim in UREG_G1 (global registers are considered
- * XXX volatile across a system call in the sparc ABI I think
- * XXX if it isn't we can use regs->y instead, anyone who depends

+ * we are safe because we stuck it into pt_regs of the parent
+ * so it will not change.
+ *
+ * XXX This raises the question, whether we can do the same on
+ * XXX sparc32 to get rid of fork_kpsr _and_ fork_kwim. The
+ * XXX answer is yes. We stick fork_kpsr in UREG_G0 and
+ * XXX fork_kwim in UREG_G1 (global registers are considered
+ * XXX volatile across a system call in the sparc ABI I think
+ * XXX if it isn't we can use regs->y instead, anyone who depends
