/* === Debug settings ===
Further diagnostic functionality than the settings below
does not need to be provided, since one can easily write a bash script
to dump the card's I/O ports (those listed in lspci -v -v):
function dump()
{
local descr=$1; local addr=$2; local count=$3
echo "${descr}: ${count} @ ${addr}:"
dd if=/dev/port skip=$[${addr}] count=${count} bs=1 2>/dev/null| hexdump -C
}
and then use something like
"dump joy200 0x200 8", "dump mpu388 0x388 4", "dump joy 0xb400 8",
"dump codec00 0xa800 32", "dump mixer 0xb800 64", "dump synth 0xbc00 8",
possibly within a "while true; do ... sleep 1; done" loop.
Tweaking ports could be done using
VALSTRING="`printf "%02x" $value`"
printf "\x""$VALSTRING"|dd of=/dev/port seek=$[${addr}] bs=1 2>/dev/null
