Anyone know how to test HWA is active? I see the build.prop lists:
debug.composition.7x27A.type=mdp
and 
debug.sf.hw=1

in Cyda's stock+ so is this enough for HWA, or is there more to it than that?

Strictly speaking:

debug.composition.7x27A.type=mdp

doesn't actually do anything. Its value is used in a composition type script. The value is set as debug.composition.type too (based on the platform - debug.composition.*plat*.type), which is what actually controls the display HAL.

debug.sf.hw=1 doesn't do anything either. Its value is default anyway. Gotta love a bit of placebo though.

You're getting confused between MDP composition and hardware accelerated UI. I'm fairly sure the latter will never fully exist on stock ROMs.

For the record, these are not values I have set. They are there by default in all stock Huawei roms.

@cyda Mmm, just looked at b936 build.prop and it is the same. @Dazzozo yeah, thought composition type controlled whether ui was handled by gpu, cpu or dynamically. Still more to learn!

Aye... They set it for 7x25A in the same build.props; they love to recycle, I guess. Half the parameters sets in the build.prop actually do nothing and some are declared repeatedly... worra joke

Paul, maybe you could try setting hwui.render_dirty_regions. Hopefully it'll work at least where hwa in actually present in the UI.

Noticed they have lines in the build.prop for HDR Camera and reject call by text. These were gingerbread options, They don't do anything now!
I could try add it, but I wouldn't even know how to test it was working. At best it would do nothing and at worst it might stop the rom booting.

Wow, they didn't even implement their own features again for ICS?

No, being pushed to have to release an ICS rom for the phone was enough! This ICS actually lacks quite a few of the options gingerbread had. I especially miss the send contact by sms.
I'm sure if Huawei could avoid it, i'm sure they would never update the firmware on their phones. They would expect you to get the next phone to get updated firmwares.

Mmm maybe. Aye, it probably wouldn't make a difference in any 2D bench, likely most of each scene will change every frame.
