Notes for the first 2 hours of the dev summit. Unfortunately, only
two people have so far sent me notes for the summit, so this is very incomplete.

<h2>Opening Remarks - Robert Watson</h2>
|
||||
|
||||
<p>Welcome to the fifth FreeBSD Developer Summit at BSDCon 2003.
|
||||
This event is sponsored by:</p>
|
||||
|
||||
<ul>
|
||||
<li><span class="sponsor">Defense Advanced Research Projects Agency
|
||||
(DARPA)</span></li>
|
||||
<li><span class="sponsor">NAI Labs, the Security Research Division of
|
||||
Network Associates</span></li>
|
||||
<li><span class="sponsor">Vicor</span></li>
|
||||
</ul>
|
||||
|
||||
<p>The sponsors covered the cost of the room, food, telephone access,
|
||||
etc.</p>
|
||||
|
||||
<h3>Growth of the Project (from BoF)</h3>
|
||||
|
||||
<p>Positive Netcraft numbers</p>
|
||||
|
||||
<p>HEAD activity maintained even when <tt>RELENG_3</tt> came out.</p>
|
||||
|
||||
<p>As soon as <tt>RELENG_4</tt> came out, <tt>RELENG_3</tt> activity
|
||||
dropped dramatically.</p>
|
||||
|
||||
<p>Large spike in commits just before
|
||||
<tt>RELENG_5_0_0_RELEASE</tt>.</p>
|
||||
|
||||
<p>About half the number of committers are working on RELENG_4
|
||||
compared to the HEAD. Implies that most commits to RELENG_4 really do
|
||||
go through HEAD first.</p>
|
||||
|
||||
<p>Slightly less than half of commits go into <tt>sys/</tt>
|
||||
|
||||
<p>Perforce submission rates are about half that of rate in the main
|
||||
<tt>src/</tt> CVS branch.</p>

<h2>Release Engineering, RELENG_4 - Murray Stokely</h2>
|
||||
|
||||
<p>Complaints about PAE stability. Definitely need to tweak 4.9
|
||||
schedule. Need to get people access to hardware to check stability
|
||||
under high load. Really need stability for non-PAE case.</p>
|
||||
|
||||
<p>Seems like a 2-week delay. sam is holding changes for MFC, waiting
|
||||
for things to settle down. dg wants the PAE stuff ripped out. phk
|
||||
thinks we're going to delay more like 6 weeks before we have
|
||||
confidence in this.</p>
|
||||
|

<h3>Discussion</h3>
|
||||
|
||||
<div class="discussion">
|
||||
|
||||
<p><strong class="speaker">PHK</strong> : Could we put this in P4?</p>
|
||||
|
||||
<p><strong class="speaker">IMP</strong> : Problem is that non-PAE
|
||||
users (who are having problems) won't have motivation to use it if
|
||||
it's not in CVS.</p>
|
||||
|
||||
<p><strong class="speaker">rwatson</strong> : What's minimalist
|
||||
backout patch? We need to get more info. Are PAE developers going to
|
||||
have time to work on this? If not, we have to kick it out.</p>
|
||||
|
||||
<p>Two-week timeline to get more information for fixing it. Need to
|
||||
be able to reproduce it in a developer environment...need information
|
||||
on workload.</p>
|
||||
|
||||
<p><strong class="speaker">peter</strong> : Things that he and ps
|
||||
would run into this problem pretty quickly. (Want to get silby in
|
||||
touch with him.)</p>
|
||||
|
||||
<p>
|
||||
"I'll just tell Paul that the next snapshot he makes has an unknown
|
||||
bug causing instability and he'll just go crazy trying to fix it."

||||

<h3>Discussion</h3>
|
||||
|
||||
<div class="discussion">
|
||||
|
||||
<p><strong class="speaker">marcel</strong> : New uart(4) driver
|
||||
supports serial console on the HP boxes in the cluster. HP boxes with
|
||||
no ISA bus emulation now supported from CVS. Should now be able to
|
||||
release for all ia64 boxes from CVS.</p>
|
||||
|
||||
<p><strong class="speaker">imp</strong> : uart(4) driver encapsulates
|
||||
lots of different UART chips. puc(4) driver is for aggregating many
|
||||
things at one attachment point.</p>
|
||||
|
||||
<p>Could we replace sio(4) with uart(4)? sio(4) is more about
|
||||
squeezing out performance, uart(4) is more about flexibility. Low-end
|
||||
performance would suck, but that's probably not the target platform
|
||||
for 6.0.</p>
|
||||
|
||||
<p>phk wants minimum hardware specs for releases. grog says that the
|
||||
people in this room are not typical users. Much debate about this.
|
||||
rwatson: Defer this for 6.0 session.</p>
|
||||
|
||||
<p>5.X efforts need to concentrate on stability and performance.</p>
|
||||
|
||||
<p><strong class="speaker">imp</strong> : Need to tie up loose ends in
|
||||
supported hardware, etc.</p>
