Hi,
It's time again for Google Summer of Code, so we need to start updating
the X.Org ideas page (http://www.x.org/wiki/SummerOfCodeIdeas) with new
ideas. Since there have been a few issues with the wikis lately, if you
have any ideas please respond to this thread, and I will make sure they
get onto the official ideas page (but still feel free to update the wiki
page yourself if you can). A good project description should contain:
I've been trying to update the wiki... I don't seem to have an account
(seems unpossible), and the account creation page is broken.
https://bugs.freedesktop.org/show_bug.cgi?id=62383
In the mean time, I have a couple ideas that someone could add.
#1. Find common patterns in real GLSL shaders.
Difficulty: Medium
Skills Required: C, C++
Helpful, but optional skills: GLSL, compilers
Possible Mentor: IanRomanick (idr on IRC)
Where to ask questions: mesa-dev@lists.freedesktop.org, #dri-devel on
irc.freedesktop.org
Descrition:
Using Mesa's stand-along GLSL compiler as a basis, generate a database
of IR from a large number of existing shaders (e.g., from shaderdb).
Write a piece of software that will mine this database for "large"
patterns that commonly occur in shaders. This information will be used
by people working on the GLSL compiler to improve code generation for
these sequences.
#2. Improved application of GLSL complier optimizations
Difficulty: Easy
Skills Required: C, C++
Helpful, but optional skills: GLSL, compilers
Possible Mentor: IanRomanick (idr on IRC)
Where to ask questions: mesa-dev@lists.freedesktop.org, #dri-devel on
irc.freedesktop.org
Descrition:
Mesa's GLSL compiler contains a large number of optimization passes.
Each pass may change the code of a shader, and this may result in
opportunities for other passes to make more changes. As a result, we
run all of our optimization passes in a loop until the shader code
stabilizes. This is expensive, and, though we have never observed this
in the wild, it is possible that a shader may never stabilize.
Find a static ordering, with possible repeats, of optimization passes
that does not compromise the quality of the generated code. Measure the
before and after speed of compiling a large set of real-world shaders.
- A brief description of the project
- A difficulty rating (e.g. easy, medium, hard)
- The skills / programming languages required
Also, I am going to purge all the old ideas from the ideas page in the
next week, so if there are any of the old ideas that you think are
still relevant, let me know and I will keep it.
The ideas page is used as one of the criteria by Google for selecting
mentoring organizations and part of the reason X.Org was not selected
last year was that the ideas page was not up to par, so if we want to
participate in Google Summer of Code this year, it is important we
have a good ideas page with lots of ideas.
Thanks,
Tom Stellard
