Re: xs-dev disk full?
Right, so I've - moved some silly logs (do we need them?) from /srv/library/mirror/log to /var/tmp/mirror-logs - compressed the logs of the joyride builds this has freed up some 345MB and I can work with that.

This last point is what I was hoping for. From other discussions, the X 1.4 driver now has scaling support. What isn't there is a release for the XO that has that driver in it. I realize that since it is open source, I should be able to put this in myself. The reality is that I am too far down on the X11+linux power curve to do this without significant time and effort. My hope is that someone who already knows how this works (e.g. OLPC?) would get this working so I could make use of it for application development and G1G1 usability features such as WINE. --Chris ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Well its not really scuttled, there will still be a equivalent release at around the time that 9.1.0 was due but it will be Fedora 11 based not Fedora 10 based. And it should be alot closer (if not almost completely) Fedora as we've been working to get all the changes upstream so they don't need to be maintained separately. > Would it make sense to have an 8.2.2 release involving > the move to Fedora 10 but pretty much the same as > 8.2.1 otherwise? The point of the 8.2.x releases is stability. Rebasing a possible 8.2.2 to Fedora 10 would be a massive undertaking.

Re: OS/X11 support for XO-1 hardware?
If you need it for some game then here is how to do it: attached. A little question to Jordan Crouse or anybody else who can answer. Here Jodran told me that the Geode can do XV flipping: http://lists.laptop.org/pipermail/devel/2007-May/005208.html It can be that he either did not reflect to that one part of my message or I am just too stupid to make it work. So what I do not see in the XV documentation is how to allocate two xvideo frames and flip between them? What this code currently does is allocating one frame and doing XvShmPutImage. Because its speed depends on the size of the xvideo frame I think it does blittting (copying) and not flipping (switching). So how to do flipping? ps: Actually I would need 3 frames for triple buffering but I would be happy even with 2 frames. Chris Marshall wrote: With the spin-off of Sugar development to sugarlabs, it is nice to see the development continued. However, it seems that the OLPC layoffs and refocus has scuttled the work to complete some OS and system software support for the XO-1 hardware features. For example, I have been waiting for the video scaler support to allow for adjustable display resolutions on the XO. Among other things, it would allow programs that don't understand a 1200x900 but only 6x4" display to work at a more usable resolution where the graphic elements and text/fonts are consistent and visible to the naked eye... It would allow for much improved video performance since you could play back a 320x240 video on the full screen at considerable CPU savings. I had thought this capability would be coming with the Fedora 10 move in 9.1.0. With that release now scuttled, I'm wondering more generally, are these pieces being picked up anywhere?

I have seen that measuring performance on the XO is quite daunting and time consuming because the state of the nand flash can radically affect observations.

Now instead of a logfile which is different from computer to computer, now I do a: time gunzip -c /usr/share/man/man1/perlfunc.1.gz ( a nice long manpage, 7958 lines 357544 bytes ) in a rxvt -fn 12x24, I have 38.772s with FBSize 8M, rxvt size 80x24 59.500s with FBSize 8M, rxvt size 98x36 33.042s no FBSize limit, rxvt size 80x24 (actually faster than with FBSize limit) 1m31.104s no FBSize limit, rxvt size 98x36 (pathetically slow) Doing anything that output lots of text is painful. For comparison, my other laptop (also debian lenny, not a fast one by any mean, AMD 1.6G single processor integrated ATI graphic) has: 1.050s rxvt size 80x24 1.306s rxvt size 105x33 ssh into olpc: 0.129s rxvt size 80x24 0.125s rxvt size 105x33 So the non-drawing part cpu time on the olpc is tiny. Something is wrong with my olpc in either the xserver or hardware. For other non-drawing tasks its speed seems to be reasonable.

I used straight rxvt -fn 12x24 just like you have, only to find it is slightly slower, now about 16 seconds. I think the problem is not in rxvt but in xserver. My olpc is debxo 0.4 installed in internal flash. Is there a xserver dpkg from debxo 0.5 file I can grab to try out?

Re: XO memory size
After generating an xorg.conf using "Xorg -configure", restarting X, results were 3.696s, 3.700s, 3.607s. After adding 'Option "FBSize" "8388608"', restarting X, results were 3.673s, 3.636s, 3.658s. The generated xorg.conf is attached. I'm not seeing what you're seeing. Perhaps there is something else affecting your system. -- James Cameronmailto:qu...@us.netrek.org http://quozl.netrek.org/ Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 InputDevice"Mouse0" "CorePointer" InputDevice"Keyboard0" "CoreKeyboard" EndSection Section "Files" RgbPath "/etc/X11/rgb" ModulePath "/usr/lib/xorg/modules" FontPath "/usr/share/fonts/X11/misc" FontPath "/usr/share/fonts/X11/cyrillic" FontPath "/usr/share/fonts/X11/100dpi/:unscaled" FontPath "/usr/share/fonts/X11/75dpi/:unscaled" FontPath "/usr/share/fonts/X11/Type1" FontPath "/usr/share/fonts/X11/100dpi" FontPath "/usr/share/fonts/X11/75dpi" FontPath "/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType" EndSection Section "Module" Load "glx" Load "record" Load "GLcore" Load "extmod" Load "dbe" Load "dri" Load "xtrap" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/input/mice" Option "ZAxisMapping" "4 5 6 7" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName"Monitor Model" EndSection Section "Device" ### Available Driver options are:- ### Values: : integer, : float, : "True"/"False", ### : "String", : " Hz/kHz/MHz" ### [arg]: arg optional Identifier "Card0" Driver "geode" VendorName "Advanced Micro Devices [AMD]" BoardName "Geode LX Video" BusID "PCI:0:1:1" Option "FBSize" "8388608" EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor"Monitor0" SubSection "Display" Viewport 0 0 Depth 1 EndSubSection SubSection "Display" Viewport 0 0 Depth 4 EndSubSection SubSection "Display" Viewport 0 0 Depth 8 EndSubSection SubSection "Display" Viewport 0 0 Depth 15 EndSubSection SubSection "Display" Viewport 0 0 Depth 16 EndSubSection SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
