<0> hi all
<1> what is the difference between:
<1> #define sti() __asm__ __volatile__ ("sti")
<1> and
<1> #define sti() __asm__ __volatile__ ("sti": : :"memory")
<2> is there a way to prevent reentry during a sys call so that I can block?
<2> or maybe there a better way than reentry from a syscall so that i dont have that wasting stack space?
<2> cause i dont think it would work.. at all
<3> Mind: reentry from syscall ?
<3> Mind: you mean like calling a syscall while bein in one ?
<3> yo edon
<4> hi r0nny
<2> r0nny, yea. well actually its more like stopping a thread from running from within the syscall. kind of like a poll() function, but without indefinite loop
<2> if i were to reenter the dispatcher wouldnt that leave a bunch of crap on the stack?
<3> Mind: you just deny the thread to be activated, till an event for it is occuring
<2> r0nny, but when the thread hits the syscall it needs a way to stop right there. would it be effective to save state and invoke a fault? or a better way ?
<3> Mind: poll is a blocking syscall - just stop sheduling the process, till you got something to return
<5> nice day today
<5> hmm when i send something to Port 60h, then it will be forwarded directly to the Controller in the Keyboard ?
<2> wouldnt that be the other way around
<6> that's the idea, yes
<5> yeah
<5> but data is received from the keyboard and commands are send?
<5> Port 64h is connected with the Controller on the Mainboard
<6> get hold of a spec for the 8042
<5> thanks jrydberg
<5> heh i found it, Port 60h will only be redirected to the Keyboard if the Controller on the Mainboard dosn't expect bytes
<5> so some commands are going to the Port 60h too
<5> such a ****
<5> with ctrl + z i overwrote my 40 sites document
<7> undo it?
<5> no it won't work, in the explorer
<5> a very old version of the doc which i have moved to another directory
<5> overwrote my ****ing doc
<8> Toaster: Isn't ctrl-y redo?
<8> Sometimes it is...
<8> Don't blame me if it isn't...
<5> i overwrote a file
<5> the physical bits on the EIDE device
<5> so its gone
<5> you can't undo it
<5> if you overwrite data
<7> XD
<7> well
<7> now you wish you had Time Machine
<7> :/
<5> yeah
<5> mhmm a good idea
<9> you do, just get ur self some data recovery program, its still there if windows hasnt placed a file over it, and it most likly hasnt
<5> it has
<10> well. don't fear. windows vista will have an idiot-proof filesystem ;)
<9> are you sure it has?
<5> yeah
<3> yo all
<9> i can pull data off my system that was deleted in 2000
<5> all what I can do is to rewrite the new content in the old one
<11> Hello
<11> i want ask about GNU C Library
<12> what's the square root of 1849?
<11> will this library rely on my syscalls?
<12> yep
<3> undesktop: such questions are not supposed to be answered
<12> what do you expect? dynamic self reprogramming? heh
<11> sorry for my bad English
<11> and with GNU C Library my kernel will be compatible with POSIX?
<3> undesktop: see what i mean
<3> undesktop: they continue to ask this kind of question
<12> hm
<3> instead of using their brain
<13> undesktop: YES THAT MOFO BETTER RECODE ITSELF FOR MY CODE
<13> or i'll be sad... not unlike a panda in a blender..
<3> darn - i hat css ;P
<12> red hat
<11> what is this ***embly ?
<11> movb $READ,%service
<3> SmartUnix: go away an learn asking questions -_-
<11> :\ Ok
<11> sorry
<3> http://www.catb.org/~esr/faqs/smart-questions.html
<12> SmartUnix: I'd follow r0nny's advice... and btw., Unix isn#t smart
<12> my ' key also isn't smart
<11> :)
<12> }:-(
<3> undesktop: the "longhorn feels bad" smiley - casue its now named vista
<3> ;P
<13> they had to rename it because it's horn was really small? :P
<3> btw - anyone cares to check out the webforum i write at http://r0nnyger.mine.nu:3300/forum/ and tell me what to do better ?
<12> Vista is just the marketing department's name
<3> nn: the name longhorn was becasue they allready knew it will have short horns ;P
<12> r0nny: design or technically?
<3> undesktop: both
<13> Odd.. our marketing department said i can't name the File Extraction, Compression, Evaluation, and Sorting library libfeces
<13> :P
<12> r0nny: seems to work, should be a bit more bersichtlicher however
<3> undesktop: yeah - thats my task atm
<6> okey, how dumb am I today.
<6> which has higher priority? cast or + ?
<14> jrydberg-: it seems they have equal priority: http://www.cppreference.com/operator_precedence.html
<6> so I suppose adding a for () doesn't hurt
<13> odd..
<13> i can't wget from this site :\
<3> undesktop: fixed die bersichtlichkeit
<12> the different colors are somehow not so good
<12> doesn't look bad overall
<15> wo
<12> bs
<13> yt?
<10> nn, you're out
<10> hello everyone.
<13> wobster: :(
<16> iiiiiiiiiiiiiiiiikk.
<15> wait. gr00ber didnt left channel after odd screamings this time :P
<3> mur: you remembered him - hes allready at the stte where heforgets parts of his paranoia
<14> r0nny: almost:)
<14> err that was for mur
<3> mur: could you ban pizza for a hour ot so - broken connections aint be nice
<3> pizza_: ping ?
<15> hmmmmmmmm
<13> r0nny: i sell pizza :P
<3> nn: good, but till its here its cold :/
<13> :P
<17> i have question about Threads
<18> why not ask it? ;)
<17> i will :)
<17> firstly sorry for my English
<17> about Treads , i understand it well , but i don't understand one point
<17> how the OS can specifies if the process need multitreads or need one thread ?
<13> the task does that, by making or destroying threads
<18> when it starts up it gets one thread
<18> and you can add more threads if needed
<17> is this mean the programmer do this
<18> yeh
<17> using syscalls of course?
<18> depends on the system
<18> if it's userspace threads, then no
<18> kspace threads, yes
<17> ok , Linux for example
<18> well, i haven't played with threads in linux, but i think it's in the kernel (does ptread use the kernel?)
<17> that's mean with OSes which have threads in kernel-space i don't need some thing like GNU Pth ?
<18> Pth?
<17> http://www.gnu.org/software/pth/pth-manual.html#threading_background
<17> The GNU Portable Threads
<18> well, you couldd use a common api ontop so that you can make it portable
<18> but you it wouldn't be requirede
<18> *required
<18> *bah
<18> i hate laptop kbds
<17> :D
<17> Thread is great idea
<17> thanks man :)
