Another Graphics Test Week has gone by, so here's the statistical recap!

A foreword - participation was substantially down this year, for which I
entirely blame myself; it kind of crept up on me and I didn't get enough
advance publicity out there. Most especially I didn't get the word out
to Phoronix, which is just dumb, because I think the majority of testers
come from there. So I'm sorry about that and I'll try and make sure it
doesn't happen for F15. If anyone else wants to take over or help out
with Graphics Test Week organization and publicity, btw, please do drop
me a line!

Here's an updated version of the numbers I came up with for F13:

f11 nouveau: 104 tests, 42 bugs - ratio 0.40
f12 nouveau: 53 tests, 34 bugs - ratio 0.64
f13 nouveau: 78 tests, 26 bugs - ratio 0.33
f14 nouveau: 39 tests, 8 bugs - ratio 0.21

f11 radeon: 55 tests, 46 bugs - ratio 0.84
f12 radeon: 61 tests, 81 bugs - ratio 1.33
f13 radeon: 48 tests, 33 bugs - ratio 0.69
f14 radeon: 32 tests, 18 bugs - ratio 0.56

f11 intel: 23 tests, 21 bugs - ratio 0.91
f12 intel: 29 tests, 31 bugs - ratio 1.07
f13 intel: 38 tests, 38 bugs - ratio 1.00
f14 intel: 33 tests, 28 bugs - ratio 0.84

Each driver posted its best ever ratio of bugs to tests, which is great
(though I imagine the Phoronix testers may be quite sophisticated and
demanding in their use cases, and this may impact the results). The
ranking stays the same, with nouveau at number 1, radeon at number 2 and
intel at number 3. The same caveats as last time of course apply -
different drivers implement different features and may have to deal with
more problematic hardware.

Here's the other chart I ran last time, tracking how we handle the bugs
that are reported - obviously, this time adding the numbers for F13 as
we can't see into the future for the F14 bugs...

f11 nouveau: 42 bugs, 4 open, 8 closeddupe, 24 closedfixed, 6 closedunfixed - 70.59%
f12 nouveau: 34 bugs, 11 open, 8 closeddupe, 14 closedfixed, 1 closedunfixed - 53.85%
f13 nouveau: 27 bugs, 17 open, 6 closeddupe, 3 closedfixed, 1 closedunfixed - 14.29%

f11 radeon: 46 bugs, 14 open, 10 closeddupe, 19 closedfixed, 3 closedunfixed - 52.78%
f12 radeon: 81 bugs, 19 open, 32 closeddupe, 28 closedfixed, 2 closedunfixed - 57.14%
f13 radeon: 36 bugs, 28 open, 3 closeddupe, 5 closedfixed, 0 closedunfixed - 15.15%

f11 intel: 21 bugs, 7 open, 1 closeddupe, 12 closedfixed, 1 closedunfixed - 60%
f12 intel: 31 bugs, 7 open, 12 closeddupe, 12 closedfixed, 0 closedunfixed - 63.16%
f13 intel: 42 bugs, 26 open, 4 closeddupe, 11 closedfixed, 1 closedunfixed - 28.95%

To refresh your memories, the percentage is 'closedfixed' / (bugs -
'closeddupe') * 100, the intention being to give an indication of what
proportion of bug reports wind up in a fix. Full details in my previous
recap -
http://lists.fedoraproject.org/pipermail/test/2010-April/090271.html .
(I know the bug counts for F13 do not match those in the previous table;
I took the numbers in the previous table from my last recap, but did
these numbers just now, and I suspect further results were added to the
F13 pages following my last recap, accounting for the discrepancy).

This one's obviously worrying and indicates our rate of closing reported
X bugs slowed markedly in F13 for all three drivers (though intel fared
noticeably better than the others). I definitely intend to look into
this. I don't think we could assume this is down to less development
effort; it could well be down to less X triage, I know I have not been
able to triage X very often for the last few months. I'll definitely
look into this and see if any follow-up action is necessary, however.

The raw lists of bugs reported from the F14 Test Days follow. Thanks
very much to all testers, and to the wonderful Fedora X.org developers
and triagers:
