What's cool about x86 assembly language?
This talk is a brief introductory overview of Intel-x86 architecture and
assembly
language for upper-division CS students who've been studying
the MIPS-32
processor and who are acquainted with the Linux operating
system.
Being able
to include 'inline' assembly language statements
in the C-language source-text
for a Linux Kernel Module (LKM),
affords students full access to all x86 features
and capabilities,
unencumbered by the normal privilege-level restrictions -- and
high-level programming-language omissions -- of most modern platforms.
Some
examples from the speaker's 20 years of experience with x86
will be cited.
