If you use --dumb then hardware-acceleration is disabled. Obviously this works ;)
Can you try with the default font? Does this work? And can you also add --enable-debug to compile flags and run kmscon with --debug. This should add much more verbose information.
Thanks!

Nope.
BTW, the built-in font, is that FixedSys?
And can you also add --enable-debug to compile flags and run kmscon
with --debug. This should add much more verbose information.
Thanks!
I posted the whole thing to
pastebin, here’s the inital stuff:

Oh! One thing I have to mention, I changed gbm_bo_get_stride to gbm_bo_get_pitch because my mesa is 8.0.4 and from my cursory look it seemed like a simple rename and otherwise it wouldn’t build.
Is this relevant?

Nah, the bo_get_pitch/stride thing was a simple rename in the development-repository of libgbm/mesa.
Anyway, I think I have found the problem. Your driver probably doesn't support GL_EXT_unpack_subimage so I've written a workaround for that. But I still need to make it look more pretty so I will push it tomorrow afternoon.
It would be nice, if you can check whether this helps (tomorrow). Thanks for the report!

I've pushed the fix. See here:

I've also pushed a fix for the get_pitch/stride conflicts. Could you give it a try?
Thanks for the report!

Yeah, it works now. Thank you.
Now, about the speed. I find the other relevant console, fbterm, is much much faster than kmscon. This is evident in cacademo, mutt, and vim. This is true in all three modes, fbdev, dumb, and gltex. Even the regular kernel console fbconis faster in cacademo. Why is that?
I also have a number of things that I could file bugs about. Are you interested in those? This is pertaining to bugs (vim and mutt background, corruptions, or unsupported codes like \033[6n) and nitpicks like font rendering.

The terminal-emulator is still pretty basic. Using TERM=vt220 should work reliably, though. But I am interested in all kind of bugs. Even better if you have information in what is going wrong exactly. Anyway, the vte layer was not of high priority, yet, but I intend to improve this now. Please file a bug-report for all of them. This helps a lot.
Regarding speed: What graphics card are you using? gltex should be way faster than any other renderer if you have a modern graphics card. On low-end machines (like my Intel-Atom N450 with integrated i915) the bblit renderer is still faster, indeed. The reasons why kernel-console or other consoles are faster is probably that they use partial-update-renderers (what I call them). That is, they redraw only the part of the screen that changed. kmscon however, always redraws the whole screen. The reason is, that this ensures that I can realiably measure delays. In other words, the console will never be slower under any circumstances. If I implement partial-redraws (which I do intend!) I can never be sure that under other use-cases the terminal may be slower.
To sum this up, I am very interested in benchmarks (any kind), but I haven't had the time to optimize this so far. I intend to implement a frame-limit, which ensures that the console will never consume unneeded CPU-times, partial-redraws (which optimized nearly all common use-cases) and bulk-rendering (pushing multiple blitting operations to the uterm library like the gltex renderer currently does with OpenGL).
But using "time dmesg" I currently can tell that kmscon is way faster than the kernel-console but still slower than xterm and similar. But as I said, there is still a lot work needed. I will close this post now as this issue is resolved (thanks again for the report). But I would be glad if you could open new reports for the other issues.
