The insanity that is Graphics Test Week is now over, so it's time for
the recap!


We had a great turnout again; thanks to everyone for testing. Here's
some interesting numbers I just pulled out...

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

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

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

The 'ratio' is the number of bugs per test. Obviously there's wiggle
room here; different people report different bugs, and some of the
drivers implement features the others don't (and hence have more
'surface area' for bugs). But I think they're quite fun anyway. Nouveau
and Radeon both regressed from f11 to f12, according to the numbers, and
got better than either previous release for f13 (at Test Day time).
Intel has stayed fairly steady. According to this analysis, Nouveau wins
the 'least buggy driver' contest by a fair margin, which is interesting!
For F13, it has half as many bugs per test as Radeon, and a third as
many as Intel. (Of course, I'm sure some of our erstwhile devs would
argue it could fairly be renamed the 'least crack-addled hardware
manufacturer contest'...)

The F11 Test Days happened in March 2009, the F12 Test Days in September
2009, and the F13 last week; these are pretty comparable points in the
respective cycles.

In terms of participation, we had the largest number of testers for F11,
with the nouveau number accounting for most of that; I suspect this is
because nouveau was very new and shiny in F11 and impossible to use on
most distros, so people were very interested in trying it out for the
first time. F12 had the fewest tests run, and F13 pretty much splits the

Since I'm getting up a head of steam, let's look at fixes!

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%

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%

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%

with DUPLICATE as the 'closeddupe' number (these are reports that should
be discarded from consideration entirely). The percentage is calculated

closedfixed / (bugs - closeddupe) * 100

i.e. it roughly indicates the percentage of genuine unique bugs reported
that have been fixed so far. These numbers are pretty close, both across
drivers and across releases; we've fixed just over half the bugs
reported. I think the outlying high nouveau result is probably a
consequence of 'low-hanging fruit' - the driver was in a pretty initial
state at that point, so the bugs exposed are likely to have been, on the
whole, easier to fix. Obviously I've left F13 out as the maintainers
have had only half a week to work on the bugs!

The raw lists of bugs reported from the F13 Test Days follow. Thanks
very much to all testers, and to the wonderful Fedora X.org developers
and triagers:

for helping to organize the events, set up the test cases, man the IRC
channel and triage - and of course fix! - all the bugs.
