Unify db_stack_trace_cmd(). All it did was look up the thread given 2004-07-21T05:07:09Z Marcel Moolenaar marcel@FreeBSD.org 2004-07-21T05:07:09Z urn:sha1:fd32d93b97086acaf80526bbb55f735b35d074fb the thread ID and call db_trace_thread(). Since arm has all the logic in db_stack_trace_cmd(), rename the new DB_COMMAND function to db_stack_trace to avoid conflicts on arm. While here, have db_stack_trace parse its own arguments so that we can use a more natural radix for IDs. If the ID is not a thread ID, or more precisely when no thread exists with the ID, try if there's a process with that ID and return the first thread in it. This makes it easier to print stack traces from the ps output. requested by: rwatson@ tested on: amd64, i386, ia64 Re-add the gdb command.

Since the feature to switch backends (and historically this means from DDB to GDB) is important, make sure people can do just that until such the generic mechanism actually sees the light of day. Suggested by: rwatson@ Mega update for the KDB framework: turn DDB into a KDB backend. 2004-07-10T23:47:20Z Marcel Moolenaar marcel@FreeBSD.org 2004-07-10T23:47:20Z urn:sha1:37224cd3fcb911d440e40dd8e1f31652e2452537 Most of the changes are a direct result of adding thread awareness. Typically, DDB_REGS is gone. All registers are taken from the trapframe and backtraces use the PCB based contexts. DDB_REGS was defined to be a trapframe on all platforms anyway. Thread awareness introduces the following new commands: thread X switch to thread X (where X is the TID), show threads list all threads. The backtrace code has been made more flexible so that one can create backtraces for any thread by giving the thread ID as an argument to trace. With this change, ia64 has support for breakpoints. Give DDB a "watchdog" command which disables all watchdogs. 2004-02-29T09:55:32Z Poul-Henning Kamp phk@FreeBSD.org 2004-02-29T09:55:32Z urn:sha1:74cc032b414cfc02eae1cc5837cbc52082bd1495 Further cleanup <machine/cpu.h> and <machine/md_var.h>: move the MI 2003-08-16T16:57:57Z Marcel Moolenaar marcel@FreeBSD.org 2003-08-16T16:57:57Z urn:sha1:26502503e57448b879c9293f18ad778c2f7e5f78 prototypes of cpu_halt(), cpu_reset() and swi_vm() from md_var.h to cpu.h. This affects db_command.c and kern_shutdown.c. ia64: move all MD prototypes from cpu.h to md_var.h. This affects madt.c, interrupt.c and mp_machdep.c. Remove is_physical_memory(). It's not used (vm_machdep.c). alpha: the MD prototypes have been left in cpu.h with a comment that they should be there. Moving them is left for later. It was expected that the impact would be significant enough to be done in a seperate commit. powerpc: MD prototypes left in cpu.h. Comment added.
