Hi,
I have finished the conversion of the UMASS driver to my new USB API. If you
have got a UMASS device laying around, and want to help the USB project,
please give the new driver a test.
I want you to collect some statistics first:
dd if=/dev/daX of=/dev/null bs=131072
dd if=/dev/daX of=/dev/null bs=524288
1)
What is the maximum speed you get before and after installing the driver?
2)
What is the maximum CPU load reported by "ps aux" before and after installing
the driver [while doing the "dd"]?
#
# How to install the new USB driver
# on FreeBSD 6.x / 7.x:
#
#
# First get all the sources
# (you need /usr/ports/devel/subversion installed):
#
svn --username anonsvn --password anonsvn \
checkout svn://svn.turbocat.net/i4b
#
# The following commands will
# install the driver on FreeBSD 6.x/7.x:
#
cd i4b/trunk/i4b/FreeBSD.usb
make S=../src package
make install
#
# Then build a new kernel (with modules)
#
NOTE: You still can't detach the UMASS device while it is in use, but this
problem is being worked on.
