Subject: [PATCH] block: Adding ROW scheduling algorithm

This patch adds the implementation of a new scheduling algorithm - ROW.
The policy of this algorithm is to prioritize READ requests over WRITE
as much as possible without starving the WRITE requests.

Maybe I will look into the SYM / CAPS key issue for the browser.

Somebody reported a problem with Wi-Fi hotspot, which I can't reproduce.

Does anybody have problems with Wi-Fi hotspot?

Anything else I should look into?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gdeliana:
Hello M66B!!!

Could you make a build without pdroid? I don't use it at all and am curious to see the battery performance :). Thanks!!!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
Sorry, I will only build with OpenPDroid.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gdeliana:
Ok, no problem. Thanks for your work!! :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pan_pietrek:
@M66B

The problem with hostpot has been described a few posts back and also here: https://code.google.com/p/freexperia/issues/detail?id=1242

I've got another question though. Does it really make sense to put so many tweaks such as IO/CPU schedulers in this ROM? I mean the won't boost the performance by that much (at all?) anyway, so what's the point really? I'm using your ROM for mainly 2 reasons: one is mass storage mode and the other is PDroid and that'd be enough for me. I don't mind some other "little tweaks" but I'm afraid that your ROM will soon end up just like many of those other uber tweaked-V6supercharged-hardcore-ricing things that incorporate bunch of patches and scripts that don't really improve anything in terms of performance and catchy, funky names are the only unique things about 'em.

No offence, or anything, of course - you're doing a damn good job here! But sometimes "just a little bit more" can be too much.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
This issue is fixed, I am sure, because I am the one that fixed it.

I have just checked and I don't have this issue anymore.

It could be your receiving device keeps displaying the hotspot for a while.

In Ubuntu I have to disabled and enable wireless to get a fresh list.

I already planned to reduce the number of CPU governors in the next release, since most will not be used anyway. Nevertheless a large number of CPU governors doesn't harm in any way.

To everybody: if you want to keep your favorite CPU governor, please let me know which.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] daniel_m:
Wow, back from a long journey and already doing business! :D

I like the interactive and smartassv2 CPU governors, but since those governors are probably not much more than different settings, I actually like the idea of having a choice here.

Btw., could you put a download link or a link to your homepage into the first post? I switched off the display of signatures, because many people here try to be as loud and big as possible ... :rolleyes:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pan_pietrek:
@M66B Thanks for the reply regarding CPU schedulers. As for the hotspot issue, well, no go. I can still see my ESSID being broadcasted even if I reboot my laptop and I can still see wlan0 listed as UP after issuing netcfg in adb shell.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
Re: {Pro/MiniPro}[ROM][KERNEL][LINARO][DEV] - CM10/FXP extended

wlan0 is for receiving access points on your phone.

mon.wlan0 is the broadcasting hotspot of your phone.

Which kernel/version are you using? This problem should really be fixed in recent FXP or extended kernels (actually ramdisk). I have checked another time and I really don't have this problem.

If the hotspot of your phone keeps broadcasting, then you cannot connect to an access point anymore, Do you have that problem too?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
Actually I need some distraction because I am still sick of bad food.

Done. I didn't know that is possible, I am going to do that do.

Edit: how can I switch the signatures off?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] mikeioannina:
Actually the problem is that support for msm7x30 is not finished in the qcom sources (hardware/qcom/display, hardware/qcom/media, etc.) and the kernel needs updates to cooperate with the new changes.

I checked everything a few days ago, codeaurora is pushing new commits for msm7x30 every few days and CM is merging the changes from CAF, so maybe in a few months we will have a working cm10.1. It's too early for now to have a working rom.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pan_pietrek:
Yes, I know it's the mon0 that "does the hotspot thing". That's what hostapd operates on, right?

I can still connect to an AP after disabling hotspot. What's more intresting is that if I enable hotspot, then disable it, then connect to an AP and then disconnect and re-enable hotspot I can see both wlan0 and mon.wlan0 up in netcfg. I'm using your latest build - the one marked as "experimental" built just before you decided to go to India and have some bad food :P

Maybe it's just that wlan0 gets brought up accidently and doesn't want to go back down? Or maybe some script brings it up while enabling mon.wlan0 and "forgets" to turn it off?

And one more thing... how can I disable signatures? :) No, seriously - how?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
Where did you get this information?

Which repo and which kernel/version?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] novicebg:
Sorry for the stupid question, but where is this fix?

And what do you tell me - if I don't have the aGPS disabled or this GPS fix installed, I will hardly get a GPS signal without the 3G on?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
GPS fix = GPS lock (not really a fix)

With aGPS enabled it is almost impossible to get a lock without internet connection (it doesn't matter what kind of internet connection).

From the external kernel/ROM page:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] mikeioannina:
I compared the cm10 & cm10.1 repositories and there are some changes/fixes for the xperia 2011 & other old phones that are not present/ported in cm10.1. I will leave a more detailed post in a few days when I have time.

About the sources, I cloned the whole CAF android tree on the latest msm7x30 tag for android 4.2 (February 01, 2013, M7630AABBQMLZA40901020) I can see now that there's a new msm7x30 tag on February 28 (M7630AABBQMLZA40901030), I will sync & check for any new changes in a few hours.

More info: https://www.codeaurora.org/xwiki/bin/QAEP/WebHome

https://www.codeaurora.org/xwiki/bin/QAEP/release

As far as I remember, there are changes required in frameworks/native, frameworks/av, hardware/qcom/display, hardware/qcom/media, frameworks/opt/telephony & semc device folders. I have forked these repos on my github but they need update. The kernel is probably the most difficult for me to fix, I don't have enough knowledge on porting kernel stuff.

The repositories used to build cm10.1 are here https://github.com/cm42semc but they are not very clean, there are unneeded changes, commits without details of what they change, etc. I will fork from cyanogenmod to start from clean sources, update only what's needed
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] novicebg:
Until now it did have ro.ril.def.agps.mode=2 . I was able to get the GPS signal after a cold start (after Dalvik cache wiped) without any Internet connection, but very hard (it was taking too much time compared to the first versions of the extended ROM - it took less than 10 seconds in the first few vers. ) until now. I will try it with value "0" and report after that if the problem with the cache wipe & phone restart occurs for the GPS to work.

Here is how it is now:

Although GPS is enabled and iGO is running, no GPS icon on the notification bar. The phone hasn't been restarted for a few days, although I clean dalvik cache maybe few times a day using Cache cleaner+. iGO even said that the GPS is disconnected!!! So if I don't restart the phone after cleaning the cache, the GPS doesn't run properly.

I'll now restart without cleaning the cache to see the result. But I think it will not work again before I clean the cache and restart the phone right after that.

EDIT: Changing the value from 2 to 0 in the build.prop only brought the phone to boot loop - it's now in a black screen after the kernel logo and can not boot. So sorry for the question, but is there any special procedure for changing the value? I did it using root explorer and replacing the original file with the modified one in the system directory.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
You're right the ssid continues to be transmitted, even though hostapd and mon.wlan0 are gone.

I guess this is a hard to find bug in the driver.

The workaround is to toggle Wi-Fi on and off.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
This means you didn't edit build.prop correctly and/or the permissions were changed. Hopefully you have a backup ...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
I have found it: User CP (top bar) > Edit Options (left) > Thread Display Options > Show Signatures
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] novicebg:
Sorry, but I'm not a developer, I don't know about the permissions - what values should they have? And with which program should I edit the file build.prop then?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Vecors:
Is it possible to keep a version with 720p? Maybe it was placebo effect, but last 203 extended was working pretty good @ recording. If it is a RAM issue, is behaving really fine compared to other roms. 720p was the best addon of your rom imho, making a big diff with your extended. :cool:

Try to keep Lulzactive and Intellidemand (specially intellidemand, wich has a great future)

As far as i know, pdroid guys didnt release last version with llama fix. U are using the same version as bfore, right?

Keep it up, we really enjoy your work :good:

cheers
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
Just look what the permissions were before you edit and make sure they get the same after the edit. Use one of the tools of the market.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
The 720p has a very low frame rate. When disabling it memory can be freed, which is more important, given there is not so much.

Noted.

The network location is fixed in PDroid, but not yet in OpenPdroid, which will not take look anymore I guess.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Somyab:
Re: {Pro/MiniPro}[ROM][KERNEL][LINARO][DEV] - CM10/FXP Extended [20130303]

+1 for 720p
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] novicebg:
OK, I've done it using root explorer.

After the ROM crashed while booting previous time, when I edited build.prop I've just reflashed the ROM, without wiping the cache. So if the ROM didn't wipe the cache while the reinstalling process, this disabling of the aGPS resolved my problem - the cache hasn't been wiped, but now the GPS is working fine found my location without Internet and for shorter time (I even did not leave the room) . I'll do some tests with hard multitasking, browsing and so on, I'll not wipe cache and reboot the phone and we'll see if that change has an effect and the GPS works fine after that.

Thanks for help, M66B!

Edit: nope, unfortunately after using wifi and browser now the GPS doesn't work again! It needs wiping the cache and restartinng the phone to resolve the problem and work again.

Edit2: I've just restasted the phone without cleaning cache and the GPS works fine again. But it's annoying to have to restart every time after using the internet, to be able to use the GPS after that.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:

Re: {Pro/MiniPro}[ROM][KERNEL][LINARO][DEV] - CM10/FXP Extended [20130303]

What's the goal of disabling the HD recording? Only gain of free memory? Even x10 was able to do HD recording with FXP!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Vecors:
I have an Xperia PRO and Ram was more than enough to use every app. I also played heavy HD games (GTA3, Asphalt7, Tintin, etc..) with this extended showing the best performance and framerate, even compared to GB, and some games even more than GB.

The only CON i find is the poor multitasking, but this is not going to improve (sadly its just 512MB). 50 extra MB wont let u multitask as a 1gb phone, face it. Even with GB we will never get enough multitasking as we want (just 2 or 3 minor apps, not even web browser... :( ).

In the other hand I must say i am a multitasking fan. The best solution i found is swap file with a good microsd's transfer rate. Not 1gb, but still multitasking and it does the job (pretty good if u use fast sd cards).

---------- Post added at 03:53 PM ---------- Previous post was at 03:46 PM ----------

Oh, I though u fixed it and was working fine (or at least better than FXP), not just like FXP before they disable it.

Ty :)

Good to hear that
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] daniel_m:
The new release seems to work fine and I like Trebuchet+ :)

I was wondering if it was possible to separate all CM-apps from the ROM and deliver them in an extra package. People who like the CM stuff can just download it as an additional zip and install it together with the ROM. The internal memory of our Mini Pro is so small that things like "CM updater", "CM wallpapers" and even the new file manager hurt a lot. There are way better alternatives out there anyways. What I dislike even more about these "bonuses" is that they are system apps ...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
Re: {Pro/MiniPro}[ROM][KERNEL][LINARO][DEV] - CM10/FXP Extended [20130303]

System apps are stored on a separate partition and do not take space of the internal memory. Furthermore the goal is to stay close to CM10/FXP (I don't like to reinvent the wheel) and these apps are part of CM10.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mysteryagr:
Re: {Pro/MiniPro}[ROM][KERNEL][LINARO][DEV] - CM10/FXP Extended [20130303]

Delete what you want from the zip before flashing it ;)

Hey man

I just compiled TWRP 2.4.3.0

it compiled fine without error in process.

The backup and restore works too but still doesn't backup .android_secure

i checked install & wipe too they too are working fine.

I did not use any patch other than the changes required in device tree.

I am including the kernel with TWRP 2.4.3.0 for Mango. It is my PA 2.57.3 kernel

Hello, as you can see in the attached pics...I have some troubles with new Trebuchet :( I tried changing number of columns but didnt worked with the hw keyboard open. Any suggestions? Great work btw porting it :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gandhar:
i can't test on the MP, but on lww, changing columns is working in both portrait and landscape.

is the setting working with the hw keyboard closed?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gdeliana:
Automatic backlight fix

Here you go, probably someone messed the numbers:

ALS FIX ->

In hwconfig change this line:

echo 0,3,3,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]

into this:

echo 3,3,3,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]

At least in my mango device it works :).

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gandhar:
i guess the mdpi resolution is too low for it to fit 5 icons + labels, to fix i'll have to reduce size of icons, which will look ugly when someone is using the stock 4x4 layout.. i'll try to find a way around if i can.

i had enabled "hide icon labels " so i did not notice.

till then tick "stretch screens" if it helps.

this is happening for lww too, nothing to do with the HW keyboard i think..
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] ncmz:
Okay, thx for answering :) For now I'll use the launcher without the bottom separator and 4x4, I can live with that lol. Hope you find a way around! Thanks for your work too.

Guys, i think my camera is REALLY broken. It's not fault of the extended rom, it doesn't even work in stock ICS, will try with stock GB. Sorry for off-topic, but i am in a very desperate point now. Has anyone had this kind of camera chip failing to initialize?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gandhar:
use this for now,

http://www.mediafire.com/?bj12fh22iiw22oz

flash in recovery..

if the camera app does not call release() and you try to get the camera again, then it says "unable to initialize camera hardware" or "can't connect to camera"

if you are using some weird camera app, uninstall it, and reboot.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gdeliana:
I installed the zip file, but still doesn't help in restoring the camera icon in the launcher. I installed then vignette demo version and it stops at the launch screen at initializing camera and after that it says a message of camera hw failed to initialize. I never thought this kind of thing that the camera could faint like that.

EDIT: Solved it after completely restoring with flashtool android ics 587 version. Phew i was damn stressed from that,but just to let you know that the reason of camera not working was because of me messing with .ko files in system/lib and not with FXP extended but with another custom ICS rom, never thought that those files could potentionally mess with the hw. Anyway thanks gandhar for the help and thanks god that it works again :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
ALS is device specific. These numbers have been the same for months, so I am a little bit wondered that you are the first to discover ALS is not working. Could somebody please confirm that ALS doesn't work for mango and that the above change fixes it?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gandhar:
here's a new build of extended rom for LWW WT19i

Rom:

http://www.mediafire.com/?cfnxpq49wgqyu8u

Kernel only :

http://www.mediafire.com/?w8z0tpqh1shwxzi

i see no problems with it as of now,

for some reason the kernel has the fxp boot logo, i'll see what went wrong next time.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] gdeliana:
I just downloaded your build dated 20130303. And this is the hwconfig.sh found inside system/etc folder of the ZIP file for mango.

It has this section:

# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 1,70,255,52,24,5,80 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,127,1,130,130,2,2 > $dev/button-backlight/als/curve # ALS curve for group2
echo 2,127,1,130,130,2,2 > $dev/keyboard-backlight/als/curve # ALS curve for group2
echo 0,3,3,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 1 > $dev/button-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 1 > $dev/keyboard-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 500 > $dev/button-backlight/max_current
echo 5000 > $dev/keyboard-backlight/max_current

so the gain for ALS is 0, that's why it doesn't function. Don't take me wrong, i am not giving the fault to you, who knows how that value changed :confused: There are a lot of developers contributing at CM code, so it can happen. At least that's what i downloaded yesterday from faircode website :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] M66B:
Gain can be zero, for iyokan this works okay.

The values are changed by me from CM, see here.

(I have already incorporated the change you have suggested, but still like to see a confirmation for this to prevent problems)
