riastradh | ddb: Don't restrict `show all tstiles' to wmesg `tstile'.
This is no longer the wmesg, as of last week -- now it's the name of

riastradh | ddb: Constify db_syncobj_owner argument.

ad | Simplify/streamline pipes a little bit:
- Allocate only one struct pipe not two (no need to be bidirectional here).
- Then use f_flag (FREAD/FWRITE) to figure out what to do in the fileops.
- Never wake the other side or acquire long-term (I/O) lock unless needed.
- Whenever possible, defer wakeups until after locks have been released.
- Do some things locklessly in pipe_ioctl() and pipe_poll().
Some notable results:
- -30% latency on a 486DX2/66 doing 1 byte ping-pong within a single process.
- 2.5x less lock contention during "make cleandir" of src on a 48 CPU machine.
- 1.5x bandwith with 1kB messages on the same 48 CPU machine (8kB: same b/w).

uwe | ddb: PR kern/57435 - fix duplicate "show mount"
Bolivar cannot carry double. One of these commands should have been
"show mounts", cf. page/pages and a few others. While here fix the

uwe | ddb: guard invocation of db_cmd_on_enter properly.
db_command_loop - do not ignore the return value from setjmp used to
guard db_cmd_on_enter. We do not want to re-execute the enter command
if it fails. Note that "fails" includes e.g. aborting long output
from the enter command with "q" at the --db more-- prompt, which is
quite likely as the default enter command is "bt".
While here, don't even bother with the whole song and dance if the
enter command is not set.

| 01-Jan-2020 |
thorpej | - Introduce a new global kernel variable "shutting_down" to indicate that
the system is shutting down or rebooting.
- Set this global in a new function called kern_reboot(), which is currently
just a basic wrapper around cpu_reboot().
- Call kern_reboot() instead of cpu_reboot() almost everywhere; a few
places remain where it's still called directly, but those are in early
pre-main() machdep locations.
Eventually, all of the various cpu_reboot() functions should be re-factored
and common functionality moved to kern_reboot(), but that's for another day.

When this file is used when not building the kernel (eg: /usr/sbin/crash)
make cnpollc() go away.
|
| 1.159 |
| 16-Sep-2018 |
mrg | call cnpollc(1) and cnpollc(0) around cngetc().
(christos has a good idea to add a function that does all 3,
and we should switch all the callers in this sequence to use
it (and fix the MD ones missing it still). not all can, as
eg, line-grabbing functions can use cngetsn(), which only
calls cnpollc() twice.)
|
| 1.158 |
| 15-Sep-2018 |
mrg | call spl0() before cpu_reboot(), so that there's a chance that:
- interrupts can work afterwards
- this also means if IO stalls, serial break might work again.
this mimics how reboot(2) ends up calling cpu_reboot().
|
| 1.157 |
| 13-Sep-2018 |
mrg | always call lockdebug_dismiss() from DDB -- there are always some
minimal lockdebug checks in place, even without LOCKDEBUG.
adjust lockdebug_abort() to ignore problems after ld_panic is set
so that there's a chance of this working.
this fixes ddb 'reboot' on softiron od1000.
|
| 1.156 |
| 13-Aug-2018 |
mrg | extend the ddb "show kernhist" command. the synopsis is now:
show kernhist[/i] [addr[,count]]
the i modifier means display info instead of entries, and the count
restricts to the last count entries.
the count option is only supported for specified histories. it
could be extended but requires more logic than the single history,
as multiple histories are merged during display.
|
| 1.155 |
| 12-Aug-2018 |
mrg | add a lockdebug_dismiss() function for DDB to use that tells
lockdebug to avoid asserts. use it for the ddb "reboot"
command, so that it doesn't matter how ddb was entered, the
reboot not trigger mutex checks and not work.

ozaki-r | Add a new command, show all locks, which shows information of active locks
The command shows information of all active (i.e., being held) locks that are
tracked through either of LWPs or CPUs by the LOCKDEBUG facility. The /t
modifier additionally shows a backtrace for each LWP additionally. This
feature is useful for debugging especially to analyze deadlocks.
The command is useful only if LOCKDEBUG is enabled.

ddb: rename show arptab to show routes

skrll | Improve ddb(4) show kernhist

switch to use strlcpy() from libkern.
|

| 15-May-2003 |
atatat | (1) Don't print the message buffer (via ddb's dmesg command) if the
message buffer has not yet been set up, mimicking code from the top of
the sysctl routine for retrieving the message buffer.
(2) Add a /l modifier to the trace command. This makes it print the
backtrace using printf() instead of db_printf(), which has the nice
side-effect of also putting it into the message buffer. A kernel with
ddb in it but disabled (ie, ddb.onpanic set to zero) will print a
backtrace (which ends up in the message buffer) before dumping (or
not, depending on the value of kern.dump_on_panic) and rebooting, but
if ddb is not disabled, the backtrace is not printed, and there's no
way to get it to display a backtrace such that you can retrieve it
after the dump. The backtrace printed by gdb is sometimes a little
different.

important as db_sym() can be called through printf() rather than

Rename the machine-specific stack trace printing functions
from db_stack_trace_cmd() to db_stack_trace_print(),

output routine (i.e. printf() or db_printf()).
Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.
Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].
Again, I'm unable to test compilation on all affected platforms,

rather than assuming it was the first entry
- add a `sync' command, which is effectively `reboot 0x100'.
- remove db_help_cmd(); it was unused (and was almost a duplicate of
db_cmd_list()).

place now

code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

(all via patch)
consolidate the handling of polling across HC drivers, and generic USB:
- don't take mutexes if polling
- normalise the code across all drivers
- add some not yet code to block discovery to/from polling
- minor CSE
- adjust comment for usbd_set_polling() to reality now i properly
understand what it is used for and why.
this, with a hack to make RB_ASKNAME to wait 5 seconds allows boot -a
work with USB keyboards. there are still multiple issues remaining:
- discovery and polling need to be mutually exclusive
- attachment of ukbd and wskbd is not handled by config_pending, and
the 5 second delay isn't going to always be enough.
call cnpollc(1) and cnpollc(0) around cngetc().
(christos has a good idea to add a function that does all 3,
and we should switch all the callers in this sequence to use
it (and fix the MD ones missing it still). not all can, as
eg, line-grabbing functions can use cngetsn(), which only
calls cnpollc() twice.)
When this file is used when not building the kernel (eg: /usr/sbin/crash)
make cnpollc() go away.
reorder some struct members to remove holes.
add config_pending usage to uhub and general USB device attachment.
- call config_pending_incr() and config_pending_decr() around attaching
devices against "usbdevif" attribute.
uhub:
- convert sc_explorepending and sc_running to bool. add new sc_first_explore.
- call config_pending_incr() at the start of uhub_attach(). dropped in
uhub_explore(), if this is the first explore.
implement a gross hack to fix "boot -a" on systems with usb keyboards on
systems with ehci handover to uhci (and maybe ohci), and fix a similar
problem for "boot -s".
there is effort to ensure that all devices attached via USB are probed
before RB_ASKNAME or RB_SINGLE attempts to ask any questions on the console,
and largely this works, often by chance, today, for USB disks and root.
i've recently pushed this more into uhub and general USB device attachment
as well, and kept a config_pending reference across the first explore of
a bus. these fix many issues with directly attached hubs.
however, on systems where devices connected to ehci ports are handed over
to a companion uhci or ohci port, it may not be the first, or even second,
bus explore that finds the device finally before attachment, and at this
point all config_pending references are dropped.
there is no direct communication between drivers, the potentials are
looked up but their device_t is only used for generic things like the name,
so informing the correct companion to expect a device and deal with the
config_pending references is not possible without some fairly ugly layer
violations or multi-level callbacks (eg, we have "ehci0", and usually an
the relevant companion, eg, "uhci2", but it is the uhub that uhci2 has
attached that will deal with the device attachment.)
with the above fixes to generic USB code, the disown happens during the
first explore. the hack works by, at this point, checking if (a) root
is not mounted, (b) single user or ask name are set, and (c) if the hack
as not been triggered already. if all 3 conditions are true, then a
config_pending_incr() is called and a callback is triggered for (default)
5 seconds to call config_pending_decr(). ehci detach pauses waiting for
this callback if scheduled.
this allows enough time for the uhub and the ukbd/wskbd to attach before
the RK_ASKROOT prompts appear. testing shows it takes between 1.5 and
2 seconds for the keyboard to appear after the disown occurs.
Index: dev/usb/ehcivar.c
- new sc_compcallout, sc_compcallout, sc_complock, and a state for th
handover hack.
Index: dev/usb/ehci.c
ehci_init():
- use aprint_normal_dev() instead of manual device_xname().
- initialise sc_compcallout, sc_compcallout, sc_complock, and sc_comp_state.
ehci_detach():
- if there are companion controllers, tear own the above, including waiting
if there is a callback scheduled.
ehci_disown_callback():
- new callout to call config_pending_decr() in the the future.
schedule this ca
ehci_disown_sched_callback():
- if booting to single user or asking names, call config_pending_incr() and
schedule the callout above, default 5 second delay.
ehci_disown():
- if disowning a port call ehci_disown_sched_callback().
deal with partial attach failures in usb_attach vs usb_detach aka PR 53598.
- make sure xhci's sc->sc_ios is NULL if failure happens.
- rearrange usb_attach() / usb_doattach() to make it simpler to clean up.
- move usb_async_intr softint into usb_once_init(). previously, each USB
controller would start a new one, and leave the old one leaked.
- handle controller interrupts without a bus attached
remove usb(4)'s "flags 1" code. it has been dead for a while,
as it runs during the interrupts part of configuration now,
and all the devices try attach as early as possible, including
any root or boot required disk or keyboard device, which is
what this flag was for.

always call lockdebug_dismiss() from DDB -- there are always some
minimal lockdebug checks in place, even without LOCKDEBUG.
adjust lockdebug_abort() to ignore problems after ld_panic is set
so that there's a chance of this working.
this fixes ddb 'reboot' on softiron od1000.
call spl0() before cpu_reboot(), so that there's a chance that:
- interrupts can work afterwards
- this also means if IO stalls, serial break might work again.
this mimics how reboot(2) ends up calling cpu_reboot().

Obtain proper initialized addresses of locks allocated by mutex_obj_alloc or rw_obj_alloc
Initialized addresses of locks allocated by mutex_obj_alloc or rw_obj_alloc
were not useful because the addresses were mutex_obj_alloc or rw_obj_alloc
itself. What we want to know are callers of them.
Spinkle ASSERT_SLEEPABLE to xcall functions
Use db_printf instead of printf in ddb
Add a new command, show lockstat, which shows statistics of locks
Currently the command shows the number of allocated locks.
The command is useful only if LOCKDEBUG is enabled.
Add a new command, show all locks, which shows information of active locks
The command shows information of all active (i.e., being held) locks that are
tracked through either of LWPs or CPUs by the LOCKDEBUG facility. The /t
modifier additionally shows a backtrace for each LWP additionally. This
feature is useful for debugging especially to analyze deadlocks.
The command is useful only if LOCKDEBUG is enabled.
Don't pass a unset address to lockdebug_lock_print
x86: avoid accessing invalid addresses in ddb like arm32
This avoids that a command stops in the middle of an execution if
a fault occurs due to an access to an invalid address.
Get rid of a redundant output
Improve wording. Fix a Cm argument.
ddb: rename "show lockstat" to "show lockstats" to avoid conflicting with lockstat(8)

sys/rwlock.h: Make this more self-contained for bool.
machine/mutex.h: Sprinkle includes so this can be used by crash(8).
ddb: New `show all tstiles' command.
Shows who's waiting for which locks and what the owner is up to.
Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE
sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>.
And thus out of <sys/param.h>, which is exceedingly overused and
fragile and delenda est.
Should fix (some) issues with the recent inclusion of machine/lock.h
in various machine/mutex.h files.
arm/mutex.h: Need machine/intr.h, machine/lock.h.
For ipl_cookie_t and __cpu_simple_lock_t.
evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL.
Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which
should really be fixed.
opencrypto/cryptodev.h: Fix includes.
- Move sys/condvar.h under #ifdef _KERNEL.
- Add some other necessary includes and forward declarations.
- Sort.
hp300/intr.h: Fix missing includes.
linux/idr.h: Need <sys/mutex.h> for kmutex_t.
amiga/intr.h: Don't define spl*() functions if !_KERNEL.
This is used by crash(8) now, and what's important is ipl_cookie_t.
cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8).
cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER.
Probably not necessary but let's be a little more cautious about
this.
atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8).
arm/cpu.h: Need sys/param.h for COHERENCY_UNIT.
Nix machine/param.h -- not meant to be used directly, pulled in by
sys/param.h.
Move the definition of ipl_cookie_t out of the kernel-only sections,
some _KMEMUSER applications need it.
ddb: Cast pointer to uintptr_t first before db_expr_t.
hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
news68k/intr.h: Fix includes. Put some definitions under _KERNEL.
next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
sys/ksem.h: Hack around fstat(8) abuse of _KERNEL.
sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
x68k/intr.h: Put functions under _KERNEL so crash(8) can use this.
Make ipl_cookie_t visible for _KMEMUSER userland applications.
fix editor mishap in previous
Explicitly include <sys/mutex.h> for kmutex_t.
Replace kmutex_t * (which may be undefined here) with struct kmutex *,
suggested by Taylor.
hp300/intr.h: Put most of this under #ifdef _KERNEL.
Only ipl_cookie_t really needs to be exposed now, for crash(8).
mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
Make inclusion of sys/intr.h explicit for spl*.
fix hppa and vax builds.
machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in
sys/types.h. avoids cpu_data.h vs sched.h include order issues.
move the hppa ipl_t typedef with the moved usage of it.
machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h.
Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which
always comes from sys/types.h. And, really, sys/types.h (or at least
sys/stdint.h) is needed for uintN_t and uintptr_t.
ddb: Cast pointer to uintptr_t, then to db_expr_t.
Avoids warnings about conversion between pointer and integer of
different size on some architectures.
re-fix hppa builds.
this file uses __cpu_simple_lock(), not just the underlying type,
so it does need machine/lock.h.
Break cycle by using `struct kmutex *' instead of `kmutex_t *'.
sys/sched.h included sys/mutex.h
which includes sys/intr.h
which includes machine/intr.h
which on cats includes arm/footbridge/footbridge_intr.h
which includes arm/cpu.h
which includes sys/cpu_data.h
which includes sys/sched.h
But there was never any real need for sys/mutex.h in sys/sched.h,
because it only uses pointers to the opaque struct kmutex. Cycle
broken by using `struct kmutex *' instead of pulling in sys/mutex.h
for the definition of kmutex_t.
Side effect: This revealed that sys/cpu_data.h needed sys/intr.h
(which was pulled in accidentally by sys/mutex.h via sys/sched.h) for
SOFTINT_COUNT. Also revealed some other machine/cpu.h header files
were missing includes of sys/mutex.h for kmutex_t.
ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t.
explicitly include no longer implicitly included sys/mutex.h.
arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz.
Sidesteps namespace collision with `#define bits ...' in net/zlib.c.
complete the previous - there were two calls to find_first_bit() to fix.
arm/xscale: Missed a spot with previous find_first_bit commit.
evbarm/g42xxeb: Fix off-by-one in previous.
The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x),
which is equivalent to fls32(x) - 1, not to fls32(x).
Note that fls32 is 1-based and returns 0 for x=0.

sys/ddb/db_command.c: revision 1.182
ddb: PR kern/57435 - fix duplicate "show mount"
Bolivar cannot carry double. One of these commands should have been
"show mounts", cf. page/pages and a few others. While here fix the
function name to be db_show_all_mounts to conform to the pattern.
