Re: SmartReflex issues
 

To activate SmartReflex, is needed to activate this two?
sr_vdd1_autocomp 1
sr_vdd2_autocomp 1

What are they?
One of it not enought?

Just trying to get some awnsers quickly.
(And yes, i know this can not work on some phones)

Re: SmartReflex issues
 

yep you need to activate both from 0 to 1 to activate smartreflex.

i used to activate smartreflex, until i found out about the awesome ultra low voltage kernels of lehto and titan, after flashing you get BETTER battery life and faster speed!

i recommend smartreflex users try it! faster than smartreflex, more battery life than smartreflex

Re: SmartReflex issues
 

What if SmartReflex and UC+OC-kernels (125 Mhz - 900 Mhz) are used at the same time? Any problems?

And would think both vddr1 and vddr2 means different things, so activating only one may do something already?
(Nope, have not read this http://focus.ti.com/pdfs/wtbu/smartr...whitepaper.pdf)

Re: SmartReflex issues
 

I'm using 125 Mhz - 900 Mhz kernel, tried active smartreflex, no sucess, phone hangs up during boot.

Re: SmartReflex issues
 

I'm sorry but that isn't true. Unless you have hard benchmark numbers, SmartReflex will win every time.

Re: SmartReflex issues
 

Do you have hard benchmark numbers? Otherwise it's all just speculation either way. I'd be inclined to suspect SmartReflex as being the safer low power option, but I don't have any concrete info either way.

Re: SmartReflex issues
 

Enabling SmartReflex on my phone and the displays stops working (ssh-remote-access _does_ work however) and the phone seems unstable and unpretictable.

I think there are enough reasons not to enable it by default at the current kernel (if the kernel has something to do with theses symptom(s)).

Re: SmartReflex issues
 

OC-kernels + SmartReflex phone not boot :X

Re: SmartReflex issues
 

The TI documentation for Smart Reflex gives you all the information you need. I don't see a reason to duplicate its efforts.

Re: SmartReflex issues
 

No it doesn't. There's absolutely zero benchmarks or comparative figures in there.

Re: SmartReflex issues
 

Just thought I'd put my input into this topic.

I tested my phone for a 20min period, twice before the Smart Reflex change, and twice after if (leaving my phone idle for 30 mins or so before testing after bootup)

Pre-hack:
1) 11mAh after 20 mins
2) 14mAh after 20 mins

Post-hack:
1) 12 mAh after 20 mins
2) 14 mAh after 20 mins

So for me at least, it doesn't seem to make a difference on idle. Whether it will or not during use remains to be seen. Although I didn't do any timed tests, I noticed the phone was less responsive and a bit slower to react. However, this could be because I read about other people's reports, so I had expected this to happen (I forget the name of the effect).

Re: SmartReflex issues
 

i have 125-825MHz OC kernel with smartreflex enabled without any problems. the battery holds for about 24hours average use when using wifi switcher to disable wlan. Used to get 12 hours max with light usage so this is no placebo.

Anyone successfully enabled smartreflex with undervoltage kernels?

Re: SmartReflex issues
 

It seems that TI has revamped some SmartReflex related stuff with recent kernel patches: http://www.mail-archive.com/linux-om.../msg26629.html

Re: SmartReflex issues
 

Smartreflex does not improve idle time. It's on the specification even!

What it does improve is use cases where the CPU is constantly not idle but not very busy either -- music playing, etc.

A 2x improvement with average use is not real.

Re: SmartReflex issues
 

Interesting.

Still, it seems to me that it does improve standby time by about one third.

And also, the N900 only freezes with SmartReflex enabled when its processor runs on max for some time.

Re: SmartReflex issues
 

Nokia has completely disabled SmartReflex in the PR1.2 kernel.
If you try to enable it, it ignores it with the warning "VDD2 smartreflex is broken".

Fixes: NB#160765 - remove sysfs interface that allows user to enable Smartleflex

Re: SmartReflex issues
 

/sys/power/sr_vdd1_autocomp can still be set to 1, but I wonder if it has any effect...

Re: SmartReflex issues
 

I tried only vdd1 and i think this only is a very big advantage.
I don't have numbers, but just for webbrowsing, idling, checking email and doing light stuff.
I think my battery life doubled

Vdd2 is unstable for me, after 1 night restart :/.

I downed the voltages also 1 jump, so 600 is on 54 and 550 on 48 and so on.

Let's see if this settings are stable for me for 1 hole day.

edit:

Normal on work i have 4 hours operation time, so fully using it, internet, little bit angry birds hihi.
Yesterday i could easy make 8 hours round and on home i still had battery, 1 hour driving with fm transmitter on, but home it was like 4mah hihi


Smartreflex > undervolting
I whatever case it's winning for me.
Only under full load undervolting is better, and full load i almost never use, i have no emulators or whatsoever and the sometimes the movies i check er max 1 min.

I need long battery live becuase overclocking even with undervolting kill my battery in a few hours.
On 600mhz with only undervolting is also nice but still smartreflex kicks it.
