Re: Simon's accelerated X development thread

X is X, so if it's compliant, then anyone who wants to substitute it out can, and creating a debian package will make it easy to do so on raspbian. What they've accomplished is what I'm trying to do in an xf86 server, but I'm definitely out of my depth (won't stop me from trying). But I'll definitel...

Re: Simon's accelerated X development thread

I won't hold my breath, phoronix reports on a lot of those efforts, and I still haven't seen anything concrete show up for my Poulsbo based netbook. I'm using Intel's official EMGD drivers (which aren't meant for netbook configurations, nor are they really deployed outside of embedded systems anymor...

Re: Simon's accelerated X development thread

Git repo up, embarrasingly basic stuff here, hoping to see if I can quickly get a driver up and running with help from that arm SoC driver referenced earlier. In typical github fashion, feel free to clone the repo and submit patches. git://github.com/Factoid/xf86-video-rpi.git Would have had this up...

Re: Simon's accelerated X development thread

Oh! Thanks for that, I'll definitely take a look. My current DDX driver doesn't get past the "Fail to allocate screen and segfault" stage. :p I think this is mainly because the probe functions normally use PCI or ISA helper functions which don't apply in this case (or at least I haven't seen any ref...

Re: Auto detection of HDMI (and eth) post boot?

I'm from the era of Amiga and the 386, and while there was a lot of stuff that didn't hot plug then either, it also didn't damage anything. It usually just didn't work. HDs and anything that needed a safe shutdown was of course an exception, but most things involving data transfer were fine. Printer...

Re: Simon's accelerated X development thread

Got everything compiled and built, was incorrectly using an outdated Mesa implementation. Of course the intel driver fails to load because the rpi doesn't have any of the intel graphics chipsets. I'm currently writing an xf86-video-rpi driver, learing about the DDX implementations as I go. So far I'...

Re: Auto detection of HDMI (and eth) post boot?

It'd be helpful if you could link to where you heard that. That doesn't make any sense to me, since HDMI is an inherently hot pluggable device. The config.txt file even has options for hdmi_force_hotplug and hdmi_ignore_hotplug. I've pulled the HDMI cable after boot and re-attached with no apparent ...

Re: Simon's accelerated X development thread

Not a lot of experience here, but would you be better off with a cross-compiler? Under ubuntu, perhaps. But due to my own set of personal driver frustration issues, I'm stuck in Ubuntu 10.10, which uses XServer 1.9. Glamor requires XServer 1.10, and Raspbian uses 1.12. So doing a vm of raspbian see...

Re: Simon's accelerated X development thread

Update for anyone else following this thread. Simon and I are attempting to attack this issue from two different sides, hoping that our combined efforts and note-comparing will yield something. There'd been a previous suggestion to look in to Glamor, which seems to use the closed OGL OVG libraries a...

Re: Simon's accelerated X development thread

I'm still trying to get my head around the Xorg archetecture and how it relates to DRM, but I went through this stuff a little bit with my netbook. It's an acer aspire one that had the misfortune of using a PowerVR GPU in conjunction with the intel Atom processor (AKA the GMA500). I have accelerated...

Re: Simon's accelerated X development thread

This seems to be the only thread I can find on accelerated X. I wanted to get involved, and my (limited) understanding of embedded GL systems is that implementing a proper hardware GLX/DRI2 layer would do the trick. Is anyone working on that angle, or any other approach to GPU accelerated X? Need a ...

Re: Sugar on Pi?

Re: Auto detection of HDMI (and eth) post boot?

Have you tried booting the RPI headless, and then plugging in into a TV? I'll have to double check with the hotplug forced on, but I don't think it worked for me. My recollection was that if you were connected to a TV on boot, then you were fine after unplugging and re-plugging. But if you started i...

Re: Auto detection of HDMI (and eth) post boot?

Yes, that doesn't cause the system to respond to changes in the state of the HDMI cable post boot. I'm talking about finding ways to make the OS aware of changes to the HDMI and ethernet port states, much the same way it would with USB. The tvservice utility included with the videocore stuff seems t...

Auto detection of HDMI (and eth) post boot?

Playing with my pi headless yesterday, I noticed that upon plugging it into my HDMI tv I wasn't getting a signal immediately. After playing around I found a work around, but I was wondering what would be involved in making this automagic? from my ssh session, running /opt/vc/bin/tvsession -p will wa...

I haven't hooked up my pi to my TV since installing the official raspbian image, but I was able to "apt-get install sugar-session-0.96" without any trouble. I'll see how it runs, but most likely any performance issues at this point will be related to X windows hardware acceleration (or rather, lack ...

I just tried out the sugar image you provided above, I'm very impressed! I bought my rpi as a first computer for my 3.5 year old son, and sugar is definitely the closest thing to what I pictured in my mind.
