How can I get the value of "%d" variables in dynamic_debug info of Linux kernel? -

-

i enabled config_dynamic_debug=y in linux kernel customized myself, , following dynamic_debug documentation shipped kernel source code, run following command enable output of debug information in bluetooth subsystem:

echo -n 'file net/bluetooth/bnep/core.c line 722 +p' > /sys/kernel/debug/dynamic_debug/control

which means debug info in line 772 of file net/bluetooth/bnep/core.c logged.

after bnep.ko module loaded, checked output of /sys/kernel/debug/dynamic_debug/control, debug information there.

but of them like:

> net/bluetooth/bnep/core.c:422 [bnep]bnep_tx_frame - "skb %p dev %p type %d\012"

i want know value represented %p or %d, don't know how it.

thank much!

you have enabled debug statement, reading /sys/kernel/debug/dynamic_debug/control tells you.

from on, debug message sent normal kernel log, can view dmesg and/or syslog daemon (which log /var/log/messages or /var/log/everything/, or similar path).

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
