JFothanks kloeri_ :)04:45
kloeri__you're welcome04:46
mtx_initsince C is a foundation for the kernel, is it also possible use another language like python?04:56
RAOFmtx_init: In linux kernel code?  No.05:06
mtx_initwhy not, given its just libraries no?05:07
RAOFBecause kernel code doesn't get to depend on libraries.05:08
RAOFIt doesn't even link to libc.05:09
mtx_initbut it does have a library it uses? it must05:13
mtx_initFreebsd uses libc, so linux doesnt?05:15
RAOFWhy would the kernel need a library?  libc *uses* the kernel to do its stuff; the kernel can't use libc :).  It has to be actually implemented somewhere :)05:21
RAOFCode *written* for linux can use libc or whatever libraries it wants.  The kernel can't, because the kernel is the thing which is providing the underlying bit-twiddling that makes the libraries work.05:21
mtx_initso lets say you want to use a basic c function like read, if the kernel doesnt use a library where does it get read from?  I mean when you compule a kernel it goes through a linker doesnt it?05:36
johanbrit doesn't get read from anywhere, the kernel can only rely on functions internal to itself05:43
mtx_inityeah but the kernel is just a image like everybody else and needed to be built and compiles with libraries. The functions still came from a library at one time or another. 05:47
RAOFNo.  No libraries.05:47
RAOFCompiled, but not linked.05:47
RAOF(Well, not to anything outside itself).05:47
mtx_initwhy does the freebsd kernel need to be linked then and not the linux?05:48
RAOFAll the “standard C functions” you can think of are implemented *on top of* functions provided by the kernel.  The kernel can't use read(), because the kernel is providing the functionality that read() uses to work :)05:49
RAOFMaybe the freebsd developers are more confident in their ability to segregate the code that can't link to anything from the code that can?05:50
mtx_initso how does a system call use read()05:50
RAOFYou mean, a call from within the kernel?  *It doesn't*.05:51
RAOFThere's a whole bunch of stuff you can't do from within kernel (linux) code.  Use the FPU, for example.05:52
mtx_initso usermode can only do that?05:53
RAOFRight.05:53
mtx_initso the kernel knows what read is but cant use it?, how the heck is the kernel pulls if the hdd then?05:57
mtx_initpulled*05:57

DanaGhmm, are the mainline kernel builds supposed to have staging drivers disabled?21:38
DanaGI need two specific drivers: r8192se, and samsung-laptop.21:38
