Re: Accelerated X driver testing

Nice. I have had troubles with this gdb being unreliable.
If you don't use startxfce4 and instead use say startlxde do you have the same issues with the debugger?

Re: Accelerated X driver testing

Thanks again. Basically the two things which have had the least amount of testing are the VpuOffload option (about a month's worth) and the SelfManagedOffscreen (about two weeks worth). With those options turned off you lose a lot of performance but is by far the most tested configuration (many many...

Iceweasel frequently hangs my Pi regardless of which driver I use (due to CPU load), and also has R/B swapped on many images with the stock driver too.

Cool thanks very much for the detail. I think I've uncovered a trouble with a VPU function, I'll see what's going on. If you can also see a trouble with VpuComposite off, can you also set SelfManagedOffscreen to false? (and just in case I'd not mentioned - any change in that config file requires Xor...

You likely have overscan turned on in your config.txt by the sound of it. http://elinux.org/R-Pi_Troubleshooting#Big_black_borders_around_small_image_on_HD_monitors (you may not be able to see a border but it's probably there hidden in the display border - are you using a TV?)

Re: Accelerated X driver testing

I future I hope to make it so that access to the VPU has a much lower latency, allowing me to send nearly all work to it (further taking the burden off the CPU). When that happens I'll also be able to properly sleep the CPU thread rather than busy waiting like you currently see. I can't do that toda...

Re: Accelerated X driver testing

Yeah, I ran top and I saw that maximum Xorg cpu load during dragging was 50-60% and the remaning load was the application itself (thunar in my case). So is it working as expected, true? I'll continue testing :) Sounds right. We saw Gearny (the text editor) taking 60% CPU time to itself simply when ...

Re: Accelerated X driver testing

Ok, if I can just run it with sudo Xorg, I can now test the driver itself. I noticed though that when I drag windows, scrolling and so on, the cpu load is still near 100%. Is it normal? Yep - however the CPU time spent in X is not necessarily 'busy', it's in the kernel just waiting for a co-process...

Re: Accelerated X driver testing

I can reproduce your error. Ah, running startxfce starts another X server, fails and then tries to run the desktop which fails as it doesn't know where the X server that is already running is. You need to export the DISPLAY variable on the console! (sadly all these display session scripts are all di...

Yep yaggi's right here - running Xorg (either via the debugger or just calling Xorg directly) simply starts the display server. You actually then need to run some programs which use the display!
