MFC 285773,285775,285776: Various fixes for stack unwinding in DDB on x86.
285773: Remove some dead code from DDB's amd64 stack unwinder.
The amd64 port copied some code from i386 to fetch function arguments and display them in backtraces. However, it was commented out and can't easily be implemented since the function arguments are passed in registers rather than on the stack in amd64. Remove it in preparation for some bug fixes in this area.
285775: Improve stack unwinding on i386 and amd64 after an IP fault.
If we can't find a symbol corresponding to the faulting instruction, assume that the previously-executed function is a call and attempt to find the calling function using the return address on the stack. Otherwise we end up associating the last stack frame with the current call, which is incorrect and causes the unwinder to skip printing of the calling function, resulting in a confusing backtrace.
285776: Let the unwinder handle faults during function prologues or epilogues.
The i386 and amd64 DDB stack unwinders contain code to detect and handle the case where the first frame is not completely set up or torn down. This code was accidentally unused however, since db_backtrace() was never called with a non-NULL trap frame. This change fixes that.
Also remove get_rsp() from the amd64 code. It appears to have come from i386, which needs to take into account whether the exception triggered a CPL switch, since SS:ESP is only pushed onto the stack if so. On amd64, SS:RSP is pushed regardless, so get_rsp() was doing the wrong thing for kernel-mode exceptions. As a result, we can also remove custom print functions for these registers.

Add new stack_save_td(9) function, which allows the capture of a stacktrace of another thread rather than the current thread, which the existing stack_save(9) was limited to. It requires that the thread be neither swapped out nor running, which is the responsibility of the consumer to enforce.

Simplify the pager support in DDB. Allowing different db commands to install custom pager functions didn't actually happen in practice (they all just used the simple pager and passed in a local quit pointer). So, just hardcode the simple pager as the only pager and make it set a global db_pager_quit flag that db commands can check when the user hits 'q' (or a suitable variant) at the pager prompt. Also, now that it's easy to do so, enable paging by default for all ddb commands. Any command that wishes to honor the quit flag can do so by checking db_pager_quit. Note that the pager can also be effectively disabled by setting $lines to 0.
Other fixes: - 'show idt' on i386 and pc98 now actually checks the quit flag and terminates early. - 'show intr' now actually checks the quit flag and terminates early.

- Special-case NMI handling on the AMD64.
On entry or exit from the kernel the 'alltraps' and 'doreti' code used taken by normal traps disables interrupts to protect the critical sections where it is setting up %gs.
This protection is insufficient in the presence of NMIs since NMIs can be taken even when the processor has disabled normal interrupts. Thus the NMI handler needs to actually read MSR_GBASE on entry to the kernel to determine whether a swap of %gs using 'swapgs' is needed. However, reads of MSRs are expensive and integrating this check into the 'alltraps'/'doreti' path would penalize normal interrupts.
- Teach DDB about the 'nmi_calltrap' symbol.

Setting the variable to 0 will effectively turn off paging. - Change db_putchar() to force out pending whitespace before outputting newlines and carriage returns so that one can rub out content on the current line via '\r \r' type strings. - Change the simple pager to rub out the --More-- prompt explicitly when the routine exits. - Add some aliases to the simple pager to make it more compatible with more(1): 'e' and 'j' do a single line. 'd' does half a page, and 'f' does a full page.

- Add support for "paging" in stack trace output. That is, when you do a stack trace from ddb, the output will pause with a '--More--' prompt every 18 lines. If you hit Enter, it will print another line and prompt again. If you hit space it will output another page and then prompt. If you hit 'q' or 'x' it will abort the rest of the stack trace. - Fix the sparc64 userland stack trace to honor the total count of lines to print. This is useful if your trace happens to walk back onto 0xdeadc0de and gets stuck in an endless loop.

Unify db_stack_trace_cmd(). All it did was look up the thread given 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.

Mega update for the KDB framework: turn DDB into a KDB backend. 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.

Initial landing of SMP support for FreeBSD/amd64.
- This is heavily derived from John Baldwin's apic/pci cleanup on i386. - I have completely rewritten or drastically cleaned up some other parts. (in particular, bootstrap) - This is still a WIP. It seems that there are some highly bogus bioses on nVidia nForce3-150 boards. I can't stress how broken these boards are. I have a workaround in mind, but right now the Asus SK8N is broken. The Gigabyte K8NPro (nVidia based) is also mind-numbingly hosed. - Most of my testing has been with SCHED_ULE. SCHED_4BSD works. - the apic and acpi components are 'standard'. - If you have an nVidia nForce3-150 board, you are stuck with 'device atpic' in addition, because they somehow managed to forget to connect the 8254 timer to the apic, even though its in the same silicon! ARGH! This directly violates the ACPI spec.

Add code to ddb to allow backtracing an arbitrary thread. (show thread {address})
Remove the IDLE kse state and replace it with a change in the way threads sahre KSEs. Every KSE now has a thread, which is considered its "owner" however a KSE may also be lent to other threads in the same group to allow completion of in-kernel work. n this case the owner remains the same and the KSE will revert to the owner when the other work has been completed.
All creations of upcalls etc. is now done from kse_reassign() which in turn is called from mi_switch or thread_exit(). This means that special code can be removed from msleep() and cv_wait().
kse_release() does not leave a KSE with no thread any more but converts the existing thread into teh KSE's owner, and sets it up for doing an upcall. It is just inhibitted from being scheduled until there is some reason to do an upcall.
Remove all trace of the kse_idle queue since it is no-longer needed. "Idle" KSEs are now on the loanable queue.

Implement db_print_backtrace() if DDB is compiled into the kernel. This MD function is just a wrapper around db_stack_trace_cmd() that prints out a backtrace of curthread. Currently, this function is only implemented on i386 and alpha (and the alpha version isn't quite tested yet, will do that in a bit). Other changes:
- For i386, fix a bug in the raw frame address case. The eip we extract from the passed in frame address does not match the frame we received. Thus, instead of printing a bogus frame with the wrong eip, go ahead and advance frame down to the same frame as the eip we are using. - For alpha, attempt to add a way of doing a raw trace for alpha. Instead of passing a frame address in 'addr', pass in a pointer to a structure containing PC and KSP and use those to start the backtrace. The alpha db_print_backtrace() uses asm to read in the current PC and KSP values into such a request.

Remove the Xresume* labels from the i386 interrupt handlers; the code in ipl.s and icu_ipl.s that used them was removed when the interrupt thread system was committed. Debuggers also knew about Xresume* because these labels hide the real names of the interrupt handlers (Xintr*), and debuggers need to special-case interrupt handlers to get the interrupt frame.
Both gdb and ddb will now use the Xintr* and Xfastintr* symbols to detect interrupt frames. Fast interrupt frames were never identified correctly before, so this fixes the problem of the running stack frame getting lost in a ddb or gdb trace generated from a fast interrupt - e.g. when debugging a simple infinite loop in the kernel using a serial console, the frame containing the loop would never appear in a gdb or ddb trace.

- One can now specify the decimal pid of a process to trace as a parameter. Since pid's are not in the kernel address space, this doesn't conflict with the funcionality of specifying an arbitrary frame pointer to the trace command. - If the first function of a backtrace maps to fork_trampoline, then this is a newly fork'd process that has not been executed yet, so just print out the first frame and then return for that case. - Lower the default count from 65535 to 1024. ddb doesn't trace into userland, and if the stack gets hosed and starts looping it's less annoying.

This commit fixes various 64bit portability problems required for FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change.
The prototype FreeBSD/alpha machdep will follow in a couple of days time.

Fixed wrong limits for the kernel text in db_numargs(). The interval [VM_MIN_KERNEL_ADDRESS, etext] was used instead of [btext, etext). Added a comment about this being completely wrong for LKMs. This only affects interpreting the instructions after the return to attempt decide the number of args. The attempt usually fails anyway.

Moved declaration of etext from <machine/md_var.h> to <machine/cpu.h> and fixed everything that dependended on it being declared in the old place. It is used in "machine-independent" code in subr_prof.c.
Moved declaration of btext from subr_prof.c to <machine/cpu.h>. It is machine-dependent.

Man the liferafts! Here comes the long awaited SMP -> -current merge!
There are various options documented in i386/conf/LINT, there is more to come over the next few days.
The kernel should run pretty much "as before" without the options to activate SMP mode.
There are a handful of known "loose ends" that need to be fixed, but have been put off since the SMP kernel is in a moderately good condition at the moment.
This commit is the result of the tinkering and testing over the last 14 months by many people. A special thanks to Steve Passe for implementing the APIC code!

Print function args in the current radix instead of always in hex.
Print the stack pointer together with the frame pointer in the trap, syscall and interrupt messages. The frame pointer is not very useful for locating syscall args since syscall functions don't have a frame pointer.
Print all the numbers in the trap, syscall and interrupt messages in the default radix. The syscall number was confusing because it was printed in decimal.
Use %#n format more and 0x%x less. 0x%x of course doesn't work with a variable radix. ddb is now fairly consistent about using %+#n to print all numbers. It omits the '+' for signed numbers the '#' in a few cases (e.g., for function args) to save space.

This is the kernel Lite/2 commit. There are some requisite userland changes, so don't expect to be able to run the kernel as-is (very well) without the appropriate Lite/2 userland changes.
The system boots and can mount UFS filesystems.
Untested: ext2fs, msdosfs, NFS Known problems: Incorrect Berkeley ID strings in some files. Mount_std mounts will not work until the getfsent library routine is changed.

Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

Fixed traceback for the following cases: - legitimate null frames from idle() (traceback was aborted after a null pointer trap) - second instruction of normal function prologue, and last instruction of a function (caller wasn't reported).

Rewrote most of the ddb stack traceback code. These changes are smarter about decoding trap/syscall/interrupt frames and generally works better than the previous stuff. Removed some special (incorrect) frobbing of the frame pointer that was messing some things up with the new traceback code.

Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference.
This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following:
rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make

Make everything compile with -Wtraditional. Make it easier to distribute a binary link-kit. Make all non-optional options (pagers, procfs) standard, and update LINT to reflect new symtab requirements.
NB: -Wtraditional will henceforth be forgotten. This editing pass was primarily intended to detect any constructions where the old code might have been relying on traditional C semantics or syntax. These were all fixed, and the result of fixing some of them means that -Wall is now a realistic possibility within a few weeks.
