Many of you are probably aware that some very bright people
who
inhabit the ps2dev forums have found a way to (legally)
"hack" the
PS3 graphics processor (RSX) and accelerate both 2D and 3D
operations. The 3D stuff has gotten a fair amount of
publicity
lately, though it is not that interesting to me since I have
no
intention of writing games in linux.
The 2D hack, on the other hand, is very interesting since it
provides
an accelerated Xorg which makes one's day to day use of the
ps3 a
much more enjoyable experience. I have installed the
accelerated Xorg
and I can say that the difference is night and day. All of
the
redrawing artifacts I formerly observed when moving windows
are now
gone as are the delays when one clicks on a background
window. The
ps3 feels like a "modern" computer now, rather
than some sluggish
first generation windowing system from the 80's.
Although I have been a loyal YDL customer, I needed to use
Ubuntu
since the hacks required a more recent Xorg and glibc than
is
currently available in YDL. However, the ps2dev hackers have
very
recently remedied this lack and have provided a patch to
allow one to
use a kernel which supports the 3D optimizations in YDL
5.01. The
diuscussion is here
http://
forums.ps2dev.org/viewtopic.php?t=9473
I am not sure whether this allows one to use the accelerated
Xorg,
but that can't be far away. One can probably do it now by
installing
a more recent glibc and Xorg, though the soon-to-be-released
newer
YDL 6 should provider all of the necessary tools.
One thing left out in the ps2dev instructions is the
necessity of
running xcompmgr (with no arguments) to eliminate the redraw
artifacts. This should run in the background, as X will be
stopped if
one kills xcompmgr or pauses it.
Good luck.
