Well I'm preparing a meeting of UNiX-freaks
to introduce them to Linux.
So I need some information:
1) Memory layout:
- programs start at base 0x0000 of their code segment. Correct ?
So no kind of relocation is needed. Correct ?
- The initial stackpointer points to adress ???
- There is some memory reserved for shared libraries. This memory starts at
adress ???
- The kernel has it's own adress space. Correct ?? <-- I assume this is incorrect,
but I don't know the correct version.
2) Linux qirx
- ioperm - syscall -> parameter
- iopl - syscall -> parameter , default value for iopl of user-programs
- sysinfo -syscall -> some information on the returned values for loadavg
- vm86 - syscall -> EVERYTHING !!!!
3) anything else worth mentioning.
Thank you
Joerg
