Here's a simple proposal.
Define an option
PRINTK_TSC
What it does: each time printk would print a newline, it will instead
print this:
(16 hex digits of TSC)\n
Here's another simpler option:
Define a new format letter, T, such that %T as a format means "time".
first option allows comprehensive timing, but it will slow things down
a bit. Second option allows us to completely tailor the printing of
time, but you have to explicitly add %T when you want time printed.
Comments?
