hi, Is it? i'm thinking that this is done by software in linux beacuse as linux not used the TSS switch when context switch,and anyway that is not relevent here in syscalls made where the process entering into kernel mode.
but i beleive that the kernel stack switch may be done in software mightbe i would be wrong. prasanna
Yes, Linux uses software task switching. But There is a per cpu tss. see, macro switch_to in include/asm-i386/system.h
and also __switch_to in i386/kernel/process.h
