After a long period of review and testing I am on the verge of
committing Hans Peter's new usb stack to -current.
The patchset requires a SMALL _493_ line diff to the main code,
mostly bug fixes to arm. And then a large number of new files
for the usb system.
The new usb system will be committed as separate files with
the intention of folding them over the old files before the
9.0 release.
The diff to the main files is here:
http://mu.org/~bright/usb2/usb2_release_001.diff
The whole diff, including new files is here:
http://mu.org/~bright/usb2/usb4bsd.diff.gz
FAQ:
Q. Has this been reviewed?
A. Yes, pretty strongly by myself and we've consulted with
various others, Warner, Scott and Andrew for review/testing.
I wouldn't say that Warner or Scott have given full review
but just about all questions have been answered.
Q. Can we change the name from "usb2_" to my favorite name?
A. No. This is for a short period, stop being so annoying.
Q. What about the old usb code?
A. What about it? :D
Q. What about ttys?
A. I don't know, we'll address the mpsafe aspects of ttys shortly,
Hans is very responsive to SMP issues.
Q. Shouldn't you wait?
A. Wait for what? No.
Q. I have some whitespace nits, can you do those?
A. No. It's a 100k line diff and a 3meg delta, we tried really hard
to get all whitespace right, but you're welcome to point things out after
the commit.
Cool! I've been waiting for this for a loooooong time. Thanks to you,
Hans Peter and all of the folks who have helped!
Not on the FAQ:
Q: Other then no longer requiring giant [MPSAFE], what does usb2 give
us?
I'm using usb4bsd on 7-stable even before 7R. It fixes few known kernel
panics for me.
I had a bad experience with base usb + GPRS card from vodafone which
works on pcmci slot but
is detected as usb device. I'm sure this is not the only improvement :)
Does it fix the battery-eating on laptops? Does it allow the
system to reach C3 and lower sleep states? (These are at least
closely linked issues.)
I have not been running current for a while and this might be enough
incentive to get me to kick the tires.
