04:33.31fog_proxyHi all. I am developing a embeded system on flash. When I do upgrade, I need overwrite the filesystem in flash, and do reboot then. My question is: If my file system is squashfs or cramfs, how to make reboot work? (because 'reboot' is a program which dynamic linked with libraries in filesystem, since I have overwrite the filesystem, it maybe wrong)
04:34.14fog_proxyI have tried to make a static bin, and store it in filesystem, not put in ramdisk(because I think before excute, loader will load it to ram); then the problem is better, but still sometimes can't reboot

15:02.07fog_proxyHi all. When I want use gdb to debug a linux kernel, how to compile it? just add "-g" option? I did that, but seems there are still many symbols can't be traced. Any suggestion?
15:02.53CosmicPenguinthe kernel really mangles the symbol space
15:03.12prpplagueusually have to use KGDB
15:03.17CosmicPenguinkgdb does a decent job of working it all out, but there are some times when you just need to use the Symbol.map and break on the memory addresses yourself
15:04.44fog_proxyCosmicPenguin: Can I just add some option for debug? for example, reduce the kernel's optimize, change -O2 to -O1 and so on
15:04.48prpplagueoh yea?
15:05.20CosmicPenguinyou can't change the optimization
15:05.20CosmicPenguinthe kernel only compiles and runs with the current optimization
15:05.29CosmicPenguinprpplague: played with diy.dispair.com?
15:05.33CosmicPenguinprpplague: its fun
15:05.38fog_proxyCosmicPenguin: I don't know how to use kgdb, I just use a emulate to help to study the kernel, which support gdb stub
15:05.57prpplagueCosmicPenguin: no, what is it?
15:06.25CosmicPenguinprpplague: try it out
15:07.04CosmicPenguinfog_proxy: kgdb knows how to massage the Makefiles to get the most out of the symbols
15:07.33CosmicPenguinfog_proxy: but really, debugging the kernel with gdb isn't like debugging a regular user app
15:07.40fog_proxyCosmicPenguin: so, what you mean is just patch the kernel with kgdb, then use gdb debug it?
15:07.51fog_proxyCosmicPenguin: I know
15:07.55CosmicPenguinfog_proxy: you need to grin and bear it, and remember that using gdb to watch symbols in the kernel is better then nothing at all
15:08.26fog_proxyCosmicPenguin: I think so :)
15:19.20fog_proxyIt's a pity, kgdb just support up to 2.6.15, while my kernel is 2.6.16
15:31.05dfarnsworthfog_proxy, kgdb is available for 2.6.18
15:31.30fog_proxydfarnsworth: so, where can I download it? I did not find it in kgdb web site
15:31.32dfarnsworthls
15:31.50prpplaguedfarnsworth: command not found
15:31.59fog_proxyprpplague: :)
15:32.20fog_proxydfarnsworth: :)
15:32.26CosmicPenguinfog_proxy: don't get distracted - you came in asking how to increase the symbol visiblity - I didn't tell to use kgdb per-say, just to see what they do
15:32.57CosmicPenguinfog_proxy: Didn't you say you are debugging a UML kernel?
15:33.00fog_proxyCosmicPenguin: ah? you mean just study the patch?
15:33.35fog_proxyCosmicPenguin: I think I misunderstand you. Now got it.
15:33.52dfarnsworthThere's a git tree: git://git.kernel.org/pub/scm/linux/kernel/git/trini/linux-2.6-kgdb-testing.git
15:33.54fog_proxyCosmicPenguin: any version will be ok
15:34.28fog_proxydfarnsworth: git? hmmm... what's that?
15:34.40dfarnsworthfog_proxy, long story :)
15:34.52CosmicPenguinI want to hear you tell it... :)
15:34.54fog_proxydfarnsworth: well, let me google
15:35.04dfarnsworthIt's how kernel source is tracked these days
15:35.14fog_proxydfarnsworth: sounds good
15:35.19CosmicPenguinOne upon this time, there was an evil ogre named Larry McCoy
15:35.39dfarnsworth... and they lived happily ever after
15:36.09CosmicPenguinI don't think anybody using GIT are happy - they're just suffering from various levels of insanity
15:36.17CosmicPenguinI
15:36.38fog_proxyCosmicPenguin: you scared me
15:36.40CosmicPenguinwhy is the ' key so close to the ENTER key?
15:36.42dfarnsworthcan't disagree too much, though I love git
15:36.54CosmicPenguinI love it too - but its a tough love
15:37.03dfarnsworthI find git much better than bk
15:37.14CosmicPenguincertainly much better for the kernel
15:37.18dfarnsworthyep
15:37.27CosmicPenguinits better then CVS and its offspring
15:37.36dfarnsworthoh yeah
15:37.50CosmicPenguinI'm neutral with regards to Perforce - I actually like perforce
15:37.50fog_proxyAny better document talks about embedded applications? smaller, faster and so on.
15:38.40dfarnsworthI've never used perforce, so can't compare
15:46.13fog_proxyCosmicPenguin: I download the kgdb patch for 2.6.13 and tried to find modification with Makefiles, but failed. Are you sure kgdb patch did any change with Makefiles?(except add some objs)
15:47.19CosmicPenguinI dunno what to tell you then
15:48.30fog_proxyCosmicPenguin: sorry for confused you, but I really don't know how to do
15:48.55CosmicPenguinwell - your main concern was that you couldn't see symbols you thought you could see
15:49.06CosmicPenguinand for that, there's no solution but to use the symbol map
15:49.20fog_proxyCosmicPenguin: yes
15:49.30fog_proxyCosmicPenguin: so, what kgdb can help me?
15:49.39CosmicPenguinprobably nothing - I apologize for mentioning it
15:49.46*** mode/#edev [+o prpplague] by ChanServ
15:50.22fog_proxyCosmicPenguin: the symbol map is just include global variables and functions, right?
15:50.32CosmicPenguinright
15:51.00fog_proxyCosmicPenguin: If I want to see the symbols for local variable, there is no solution?
15:51.24CosmicPenguinOk - lets start over
15:51.45CosmicPenguinyou said you built with -g, but you're not seeing the symbols you think you should be seeing?
15:51.50CosmicPenguinAnd again, you are using UML?
15:52.27fog_proxyCosmicPenguin: I am sorry, don't know what is UML
15:52.35CosmicPenguinso the answer is no
15:52.43fog_proxyCosmicPenguin: ok
15:52.50CosmicPenguinWhat exactly are you debugging?
15:53.26fog_proxyCosmicPenguin: linux kernel 2.6.16, I just use qemu emulate, and try to study how the filesystem work
15:53.56CosmicPenguinI have absolutely no idea how to do kernel debugging in qemu
15:54.03CosmicPenguindo you have a tutorial?
15:54.39fog_proxyCosmicPenguin: yes, qemu have a buildin gdb-stub, and I can use gdb to do remote debug now.
15:55.45fog_proxyCosmicPenguin: The only problem is, sometimes when I traced in a function, I can't check values of local variable, such as a return value from a sub function.
15:56.01fog_proxyCosmicPenguin: that make my trace difficult

17:20.34prpplagueCosmicPenguin: you got a good url for automake syntax
17:21.56CosmicPenguinhell no
17:23.43prpplagueCosmicPenguin: hmm
17:24.24CosmicPenguinautomake doesn't get documented, it just happens
17:24.48prpplaguehehe
17:25.15prpplagueCosmicPenguin: well i need to do a if/else block with an "or" but can't seem to get the syntax right
17:25.32CosmicPenguinits just shell synta
17:26.43prpplagueCosmicPenguin: thats what i thought, and i figured it would honor it , but it doesn't seem so
