Bochs/bochs/patches/patch.logfilefmteip
Christophe Bothamy a926744628 I reworked and included Carl's patch to have a new bochsrc directive 
to describe the format of the log prefix. This option can be any string
with special tokens being replaced at run time :
  #   %t : 11 decimal digits timer tick
  #   %i : 8 hexadecimal digits of cpu0 current eip
  #   %e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
  #   %d : 5 characters string of the device, between brackets
the default is "%t%i%d", so the logprefix is the same as before.

New tokens can be easily added or changed if needed.

Original Detailed description:
While working with Bela Lubkin of Caldera, trying to
get bochs to install SCO OSR5, Bela asked me to add the
EIP to the log file. The attached patch changes the
timestamp portion of a log file entry to
tttttttttt-x-@eeeeeee[sssss]
where tttttttttt is the ticks, x is the type of entry
(error, panic, info, debug), eeeeeeee is the EIP (in
hex), and sssss remains the subsystem (e.g., HD, FDD,
BIOS, etc)
Please make this part of the standard bochs package.
Thanks,
Carl
