 Posted: Tue Oct 15, 2002 5:54 pm Post subject: does hardware acceleration work on ibook2 |
 |
|
I was wondering if you can get the mobility radeon to do hardware accel on the ibook2 (dual usb,700mhz 12") also if someone has a complete XF86config for the ibook2, can they post it. Thanks.
Also has anyone tried the videolan client (videolan.org) under the ibook? How is the preformance? |

until recently i though this wasn't possible at the moment because of the a radeon frame buffer problem with the mobility M6 LY, that why i suppose you get this message in your X log :

the good line is the one whith direct rendering enabled, the only problem is that with the disabled acceleration i can use X, but with the enabled config i just get a awfull screen absolutly unusable...
the only difference between the two situation is the kernel, i didn't touch the X config. i don't have time to dig this right now but if someone wants to
try...

I get purple horizontal lines spaced approx 8 pixels apart, and the "X" cursor takes up about a 64x64 pixel area of confusion. Does this sound similar? If I take the radeon DRI driver out of the kernel, X works normally, but without DRI. Put radeon DRI in, and set to 16 bits color, and purple sideways jail cell. This is with 2.4.20-pre9-ben0 on a TiBook Gen III.

yeah you actually describe it way better than i do but that just the picture i've got.
Note that trying as small resolution (something like 640*400 and 16 bits i don't recall exactly) i was able to get something that was looking like a very flickering and messed xterm and this "thing" was actually responding to keyboard input i was even able to kill X to get back to console prompt.
i think the solution is close to us...

I got vlc working. it will play encrypted dvds, but a bit jerky. I tried out the latest benh kernel tonight, and got similar results to those above. It claimed DRI was on!
check out http://www.desertsol.com/~kevin/ppc
I've posted my XF86Config-4 there and just about everything else, too.

|

Here you can find my XFree86 and kernel config files, for completion's sake: http://spanbroek.net/mark/laptop/ibook/
DRI has been disabled for now, because of the 'interesting' display effects, but XVideo (and therefore playing movies) works. I have a 600Mhz model without DVD, so I couldn't test playing DVD's, but playing divx movies with Xine works perfectly.
You will need the latest benh kernel for now (I use 2.4.20-pre9-benh0), because the sound driver in the latest gentoo ppc kernel sources doesn't work properly. More info about the benh kernel can be found at http://penguinppc.org/~benh/ |

your mileage may vary with recent benh kernels... my quicksilver refuses to boot at all with anything in benh tree in last month or so, also there were some _huge_ memory leaks for the ones i did manage to boot before that. Word of caution for anyone that might be trying this on production machines  |

| Posted: Mon Oct 21, 2002 10:01 pm Post subject: about benr kernel stability |
|
|
i would like to share my experience with benr kernel vs gentoo kernel on the ibook. until 2 weeks ago i was using the r6 gentoo kernel on a new ibook2. I've had a hand full of crash (about 2 time out of 3) when resuming after going to sleep mode.
With the latest benr tree i haven't got a single crash in 2 weeks of intensive use...
am i the only one finding that benr kernel is more stable on the ibook than the ppc-kernel ??? |

strange. I've been using ppc-sources r6 for a month, and I've never had a crash or any problems at all.
I just switched to the 2.4.20-pre9-ben0 kernel
on friday, and after disabling the dri it has worked well for me too.
only problem is that both kernels give jerky dvd
playback. xine is quite bad in both kernels, vlc is much better in the benh kernel but still drops at least a couple frames every second.
my machine is the 700mhz ibook |

hi
just picked up 2.4.20-pre11-ben0 and installed from ppckernel.org and threw it in the iBook2 500, with great results, incl. hw accl. got the sound working using the install instructions linked to on the "special kernel" page referenced on ppckernel. still haven't tested networking or dvd playback.
my 2c. Keep up the good work benh and gentoo ppc folks!

hmmm...networking not up on the kernel mentioned above, even with provided tweak from the ppckernel site.

I'm not sure about that, but I managed to have a Radeon M6 LY working under Gentoo, using the previous address http://spanbroek.net/mark/laptop/ibook/ .
I'm not sure it's XFree 4.2.1 or the last benh kernel or the XFree86Config-4 file... But it's working ! without DRI but without the FB driver too !

Me too (and a lot of other i think) have the radeon working under gentoo. But the real problem is getting hardware accelerated video. And i haven't heard of anyone succeeding in doing this, even on a X86 laptop running linux and sporting a RADEON mobility M6 LY...
regards.

I don't know what exactly you mean by hardware accelerated video, but on my system 2D hardware acceleration (the DGA, XAA and XVideo extentions) works flawlessy. The only thing that doesn't work yet is 3D hardware acceleration (the DRI extention). |
