I don't know if it's ok for me to post here, but I can confirm hat the N5110 is booting Replicant 6.0 0004 rc1 correctly.

The graphics performance is ultra slow, 2 or 3 times slower than on the N7100 which has similar specs. It's borderline unusable, I think it should be mentioned somewhere. But that was already the case with 6.0 0003, so it is unrelated to 0004 (rc1).

Thanks a lot for the report.

Is the 2 or 3 times slower in portrait or landscape?

What happens when you switch orientation?

I've only now tested this because the default is portrait - but the graphics seem to be much faster in landscape mode. In landscape mode, they're about equivalent to a N7100 in portrait mode, about 15-20 fps. In portrait mode, you only get 6-8 fps (rough estimate) on the N5110, while doing basic tasks, and it feels extremely sluggish. I personally prefer portrait mode on the N5110, for browsing and reading PDFs or eBooks.

Should we open another issue for this problem?

David said on the replicant irc that, on Replicant 6, RGB555 is used throughout the entire stack.

Denis said we probably need RGB565 instead of RGB555 on Replicant 6 because neither omap nor exynos have the RGB555 DRM database format.

Denis then said that for Replicant 6 his recent patches probably unbroke booting on the Galaxy Nexus but broke booting on other devices.

Yes, please open another issue since this issue is simply about whether the devices boot or not.
