Hello everybody
This time I want to post some information and questions about binary
blobs situation on Exynos5 devices. It means Samsung Chromebook and
Andale Board (I do not have data about other Exynos5 powered devices).
Chromebook ships with Chromium OS and under it has working OpenGL ES and

Hi Viresh,
I test your updated branch, and find there is some errors:

Hi Tixy,
I can now reproduce it with MMC too, and the times are pretty much the same for
me :(
There is definitely some interaction with CPUFreq, the A7s stay at a low enough
OPP
that the busy threads during boot are never able to accumulate enough load to
migrate up to an A15. Normally, it mak

I use ARM's bootmonitor for booting. My setup should have the same
firmware and boo
Hi Tixy,
It seems that at least on my board, the presence of so many MMC timeouts causes
the A7s to remain at the lowest frequency, presumably because the system load
average is so low. With the frequency-invariant patch, this has the side effect
that no tasks ever get to run elsewhere.
Do you
Well, I didn't find any problem with USB boot. I'm just setting up u-boot to go
for a completely standard MMC boot and I'll continue to try to reproduce.
Tixy, could you try temporarily changing the default option to off for the
frequency-invariant load?
I think it'll be at line 3631 in your fa
