Should work.

zoubidou · Jul 15, 2011

does it support encryption (thus it supports enterprise emails -exchange-), otherwise i have to live without it.

caz70 · Jul 16, 2011

first of all, big thanks to roggin and you for releasing this kernel. And of course to all the others who paved the way to this point.

i've created my own custom image tonight which is based on the .22 image (unfortunately the .30 download link was gone). So far it works and i'm happy for now.

But i noticed that the usb connection got interrupted after the screen blanked. I've never noticed this before (it might be that i haven't copied larger files so far, so probably that would happen with the default kernel as well).

Could it be that the power saving code turns off the usb connection ?

Question
how to save "stock kernel"?

I would like try this kernel then maybe swap back to stock?

duongla · Jul 16, 2011

@richardtrip
Please create stock kernel backup for roll back purpose. Thanks.

netarchie · Jul 16, 2011

Can I flash over my stock acer rom? Or do I need to install a custom rom first?
At the moment I just need all the features this kernel offers.

Thanks

The thread title says this kernel is for stock ROM

_motley · Jul 16, 2011

Nice work richard, glad to see roggin's kernel get posted with a little overclock action! I am very excited that there is a true open source git going now.

Here is a CWM zip to flash back the stock 3.1 Acer kernel (official release) including the two stock kernel modules (bcm4329.ko and scsi_wait_scan.ko). I have been working on my own custom kernel and first created this so I could flash back to stock 3.1 whenever I wanted to test the differences.

Flash using thor CWM with itsmagic...this does NOT have itsmagic built-in

I still recommend backing up your own system and boot partitions in the latest stable CWM.

A great kernel! We have now a truly open sourced 3.1 kernel that works perfectly with stock 3.1 ROM.

I have also modified roggin's kernel with OC & some cherry picks from other kernel guru including OP's commits.

Quadrant score get over 32xx which is very promising. Thanks again for all the works.

EDIT: One thing I notice is that the speed of obtaining IP address is drastically increased! After opening the wifi tether of my mobile phone, A500 obtains IP address almost instantly! (when comparing with stock kernel)

chlballi · Jul 16, 2011

I just flashed this a few minutes ago. How do you use the native NTFS support?

I'd really like to find out why I only pull off half off that score @ 1.5ghz. Using this kernel and stock 3.1 ota. I used to score alot higher.

roggin · Jul 16, 2011

Hi richard,

Coooool, nice work, It's what I love to see

Every cool developer can add his nice work to the kernel, and we will get the best kernel here

Thanks

zoubidou · Jul 16, 2011

ok i did not get the answer, but i checked on myself: encryption is working, so exchange sync is possible.

excellent.

everything seems to work so far including O/C using setCPU.

using 1408 i got a quadrant score of 2368 (second test, because the first one always gives the wrong result)

Well to clarify, I just did three runs back to back and the highest I got was 2652, which is alot better for 1.5ghz, but a far cry from the 3400-3600 I used to get before 3.1. Oh well no biggie. I'm back on 3.1 stock with the .38 ota update while waiting for Acer to put out something even half as decent as what these XDA dvs release. Looking forward to 3.2 coming down the pipe. Great job on the kernel by the way, I'll more than likely come back to it in a week. Still waiting on somebody to of the gpu like with Xoom tiamat, just for comparison and because I like to push my hardware.

ardatdat · Jul 16, 2011

Maybe I have modified to use 400 gpu such that I get over 32xx.
By the way, Acer must have some tweaks to make the stock kernel faster than this one.

FloatingFatMan · Jul 16, 2011

Don't be setting too much store in benchmarks, guys. All they do is measure artificial tests and rarely, if ever, have anything to do with real world performance.

Benchmarking is, and always has been, a load of complete cobblers, on any machine.

Hi cq842000,

so you get 3400-3600 in stock 3.1 Acer's kernel ? Or it's in 3.0 kernel ?

Thanks
