[Dev] CyanogenMod 7.2.0+ Galaxy5 Port

[psyke83]

News: The galaxy5 device is now officially supported within the CyanogenMod project - I am the device maintainer. This means that in future, you may see future release or weekly builds for the 7.x branch on the CyanogenMod website.

Even though I am an official CyanogenMod developer, you should not consider the builds that I release here as official. I have applied several patches to fix minor issues that are not yet part of the official CyanogenMod code (such as FM radio popping, camera crash on zoom, etc.).

  • Hotfix 3 [18th April]: kernel: fix shutdown issue.
    
  • Hotfix 2 [16th April]: kernel: enabled CGROUPS + CFQ IO scheduler (seems to reduce lag), various patches to improve performance/stability; g5sensord updated to v3.4 (low pass filter to reduce compass needle dancing).
    
  • Hotfix 1 [10th April]: kernel: fix headset detection problems, experimental change to improve stability when rebooting to recovery; g5sensord updated to version 3.3 (corrected bug in calibration file, hack to stabilize compass on high pitch)
    
  • Updated CyanogenMod source - version 7.2.0 RC1.
  • New kernel (label: You are not allowed to view links. Register or Login). Based on Samsung Gio Froyo source, updated to latest Code Aurora froyo_almond revision. This kernel has a more accurate battery driver, more efficient power saving for the mmc (wifi/sd) interface, and includes many fixes from Samsung and Code Aurora Forum in contrast our original kernel source.
    
  • New wifi driver + firmware (3.0.70.23, from Samsung Gio Froyo system image). This wifi driver is more recent than our official source, has better mmc power management code, and appears to be more stable. The minimum CPU frequency also set to 122Mhz (really). This frequency usually caused sleep of death issues, but this new driver may be immune.
  • Various patches for memory leaks and minor bugs from gerrit.
  • Updated sensor daemon (g5sensord) to latest revision (v3.1) - adds calibration data persistence, calibrated data and magnetic z-axis, saving of hard and soft iron calibration data. Should fix the Google Sky sensor issue. Thanks OuNao!
  • Enable setup_fs tool by default. This tool will check /data and /cache on each boot, ensuring that they are formatted properly as ext4 filesystems. If not, the partitions will be formatted automatically. This should make upgrading from Froyo more painless, and also fixes a common issue in which /cache corrupts randomly (perhaps due to unclean dismounts when the phone is not rebooted properly).
  • GooManager support now working correctly, which allows for future OTA updates.

  • Hotfix 1: changed kernel config (to test for battery improvements), re-enabled WOW suspend in wifi driver
    
  • Updated CyanogenMod source - version 7.2.0 RC1.
  • Cherry-picked various patches from gerrit to fix issues with core binaries/libraries (dalvik, bionic, zlib, etc.).
  • Kernel: updated europa-battery, pmem, fsa9280, android staging drivers.
  • Kernel: reduce minimum CPU scaling frequency to 122Mhz (to see if sleep of death occurs with the new wireless driver).
  • Wifi: using AR6kSDK.3.0_RC.298 source with patches to allow usage of Samsung's firmware blobs, disable WoW (Wake on Wlan), and fix a certain case in which the driver blocks suspend. Note: the newest driver from freescale (AR6kSDK.3.1_RC.563) is not stable with our phone. This can't be fixed easily, as the problem appears to be within the new proprietary firmware blobs, which is something I can't fix. In the meantime, this driver should work well (and hopefully without any sleep of death issue).
  • dhcpcd: patches to optimize dhcp requests for Atheros AR6003. This improves connection/reconnection speed and reliability.
  • libhardware_legacy: increase wifi loader timeout from 1 second to 5 seconds. This ensures that the wireless driver is given time to settle before the first scan occurs.
  • wpa_supplicant_6: wait for control interface monitor to be brought up before starting. Improves reliability of wireless when reconnecting from idle.
  • libaudio: fix for minimum in-call volume being incorrectly muted in certain cases (including on speakerphone); fix FM audio when using no-microphone headphones.
  • Switched to OuNao's open libsensors - completely fixes accelerometer lag.
  • Switched to "g5sensord", Ounao's open memsicd replacement based on freescale's eCompass code - more battery efficient than proprietary memsicd daemon.
  • GPS: use worldwide SUPL server by default. Initial reports indicate that people are having better connectivity with this setup overall.
  • Compcache: back to 18%.
  • ADWLauncher: lock action buttons by default (helps avoid cases in which users accidentally detach the icons for these buttons).
  • Change scrolling cache setting to further improve scrolling speed.
  • Disable automatic brightness setting by default. Our phone has no light sensor, and I suspect that the software implementation may be causing battery drain.

  • Hotfix 2test3 [10th March]: Kernel: reverted all changes since v2.0 release (to hopefully prevent battery drain); ar6000: avoid setting refClock rate (may improve wireless stability); reverted to CyanogenMod wpa_supplicant v6.
    
  • Hotfix 2test2 [8th March]: Same as hotfix2test1, but using stable kernel instead. Please compare against hotfix2test1.
    
  • Hotfix 2test1 [7th March]: Reintroduce CodeAurora kernel with fixes for battery usage (but further testing is needed by the community); updated new ar6000 driver to match suspend/resume/bluetooth coexistence behaviour of stock driver; switched to wpa_supplicant & hostapd 0.8.x from Atheros SDK to improve wireless behaviour; fix FM audio when using no-microphone headphones.
    
  • Hotfix 1 [6th March]: New wireless driver (AR6kSDK.build_3.1_RC.563) from Freescale i.MX53 source release - wireless is now stable. Modified source is available on You are not allowed to view links. Register or Login (freescale branch).
    
  • Updated CyanogenMod source
  • New ar6000 driver (adapted from AR6kSDK3.1 source package used by the Sony PRS-T1/JP e-book reader); enabled combo scanning in wpa_supplicant_6.
  • libaudio: fixed combo device issue (ringtone in speaker + headset/headphone)
  • libsensors: using OuNao's libsensors with change to further reduce battery consumption during idle. This completely fixes sensor lag. Thanks to OuNao.
  • Adjusted smartassV2 CPU scheduler to idle at lower frequencies
  • Enabled CGROUPS in kernel to minimize data starvation issues.
  • Updated fake-dualtouch module to v9.1 (fixed).
  • Enabled Goo-inside.me OTA update support (requires You are not allowed to view links. Register or Login)

  • hotfix 2 (6th February): more fixes for microphone and headset routing. I can't reproduce call echo, so it may or may not be fixed.
    
  • hotfix 1 (6th February): due to popular demand, the microphone has been enabled to allow voice calls. [sarcasm]In future releases this will be a paid feature.[/sarcasm]
    
  • Updated CyanogenMod source (almost 7.2.0-RC1).
  • Kernel: updated OuNao's dualtouch module to the latest version (v9.1, which also has edge sensitivity fix).
  • Kernel: updated android staging kernel drivers from 2.6.35 kernel (notably bringing improvements to the lowmemorykiller driver).
  • Kernel: audio driver patches to prevent rare blackscreen during incoming calls from idle/low memory conditions.
  • Framework: disable scrolling cache (prevents lag in certain apps).
  • Framework: switched to stable copybit version with blending bug fix.
  • Audio: further updates to latest CAF libaudio version with FM support added. Bluetooth calling needs testing (I don't have a peripheral to test).
  • Camera: fixed force close error during zoom.
  • Mobiledata: added 2g/3g mobiledata switch option (you can set the mobiledata button to switch between 2g/3g mode instead of simply turning on/off data)
  • FM: Fix audio routing (where headphones sometimes stopped working after closing the radio app); respect upper and lower frequency limits; looping between low/high frequency limit during manual seek is now possible.
  • Network: SIM lock messages will no longer be ignored. This may help people who have problems using SIM cards that require a PIN unlock (note: this is not related to the reboot problems with certain SIM cards).
  • Updated USBController.cpp (tethering) code to possibly prevent reboots after extended use.
  • Refreshed ClockworkMod Recovery official build to 5.0.2.8 (thanks to koush)
  • Moved to new hosting on goo-inside.me (thanks to DrMacinyasha), which allows for better ROM Manager integration. This also means no more weekend download restrictions!
  • Improved LatinIME key sensitivity (key presses are recognised with better precision than before).
  • Settings -> About phone -> Mod version will now show the exact build date, which helps you to know exactly what version you're running.
  • Update notifications & automatic ROM updating now available (ROM Manager Premium users only).
  • Increased compcache to 26% (may be useful for those who have no swap).
  • Decreased wifi scan interval to 45 seconds to help with reconnection problems if you use hidden SSIDs.
  • Switched to US GPS servers by default.

  • Data wipe?: only if you have problems / forgot to disable mad2sd properly before upgrading.
    
  • You are not allowed to view links. Register or Login [7 September 2011]: Kernel: experimental config changes for better battery savings. Framework: fixed lag on incoming call; small fix to "mad2sd" script (note: it is only used to control swap).
    
  • You are not allowed to view links. Register or Login [27 August 2011]: Modified kernel config to reduce SD lag; reduced VM heap size to 32Mb; potential fix for lag on incoming call; modifications to better support S2E - its script will now mount the drive with its own parameters, giving better performance. Important: Due to changes in the way S2E works, you must move all folders back to internal memory (and make sure to do a full reboot), before installing hotfix1. When you flash hotfix 1, you should also format /sd-ext, or else you will have problems. See: You are not allowed to view links. Register or Login.
    
  • Updated CyanogenMod source.
  • Changed default configuration: 48Mb VM heap size, 18% compcache memory usage.
  • Fixed tethering via 3g.
  • Boot: removed mad2sd, updated CyanogenMod's existing script to properly mount /sd-ext drive as ext4 format.
  • Kernel: small fixes, now built using gcc version 4.4.3 (to increase compatibility with existing proprietary kernel modules).
  • Kernel: rebuilt wifi module using original, unmodified source.

  • Known issue (not directly related to this release): If you cannot access Google Apps after flashing, you are using a buggy version of ClockworkMod v0.4. Please re-download CWM v0.4 from the latest link in the other topic, reflash CWM, reboot into the fixed CWM, and then flash Google Apps once again.
    
  • Known issue: If you experience the sleep of death issue, make sure you upgrade to hotfix 1.
    
  • Data wipe?: recommended if you have problems.
    
  • Hotfix 2 [14 August 2011]: More fixes to FM routing code (thanks to OuNao); fixed compass direction issues (x2); upgraded brcm_patchram_plus tool; changed hciattach service parameters. Bluetooth initialization should no longer fail, and Bluetooth SCO operation may be fixed/improved - please test.
    
  • Hotfix 1 [13 August 2011]: Increased minimum scaling frequency to 245Mhz. This is necessary to fix sleep of death on some (but not all) phones. If you know that 122Mhz is stable for your device, you can manually set the lower frequency.
    
  • Framework: updated CyanogenMod code (more Gingerbread 2.3.5 code merges).
  • Framework: increased default camera exposure level.
  • Framework: more updates to libaudio FM routing (still needs more work).
  • Kernel: fixed compass direction issues.

• You are not allowed to view links. Register or Login - 2 August 2011:
  • Known issue: wifi sleep of death bug is present. Fixed in hotfix1+.
    
  • Hotfix 1: Boot: reduced default minimum frequency to 122Mhz. Kernel: improvements to CPU schedulers, KGSL driver, disabled CGROUPS (it causes slowdown), improved wifi kernel driver. Framework: changed camcorder recording format (playback now works), fixed wifi sleep of death issue.
    
  • Data wipe?: recommended if you have problems (since it is a new Gingerbread point release).
    
  • Framework: updated to Gingerbread 2.3.5 code release.
  • Framework: improved camera quality - should now match or exceed Froyo's camera/video quality.
  • Framework: small fixes to libaudio, and beginning of work to support FM radio (not ready yet).
  • Boot: increased disk readahead cache; various bugfixes & improvements to mad2sd script & init.rc script - reduces startup delay and fixes bootloop problems for some users with slow SD cards.
  • Kernel: reduced sensor wakeups by 50% (less wakeups = less battery used); fixed disk-related stability & SD card lag problems; now using zram.ko module (newer compcache version); improved wifi reliability; improved overclock stability (kernel will now initialize at safe 604Mhz frequency); increased default minimum frequency to 245Mhz to avoid lag when resuming from idle; small improvements to smartass scheduler; re-enabled CGROUPS support; enabled CGROUPS support in BFQ scheduler.
  • Summary: new Gingerbread release, more stable kernel, faster SD card speed, better camera quality, improved battery life.

  • Data wipe?: not needed.
    
  • Known issue: it's very fast...
    
  • Known issue (really): cannot hang up calls. Fixed with hotfix 1.
    
  • Hotfix6 [20 July]: Framework: reverted to wpa_supplicant v5 with patch for reconnect issue. Wifi is now 100% stable, including reconnect from idle .
    
  • Hotfix5 [20 July]: Boot: increased mad2sd reliability. Framework: now using patched wpa_supplicant_6. This appears to almost completely fix wifi reconnection, but the reconnection may not happen unless you open the Settings -> Wifi menu for some reason. I'll continue troubleshooting, but in the meantime this is a big improvement.
    
  • Hotfix4 [19 July]: Boot: fixed problem with mad2sd script (some people could not activate); fixed incorrect ramzswap module loading. Kernel: really add smartass 122Mhz sound fix (please re-test again). Wifi: backported some patches from 2.6.35 kernel to increase stability of ar6000 module. Framework: replaced Samsung wpa_supplicant with CyanogenMod version (it was causing Google account sign-in problems, and it's just Samsung's dhcpcd that's required to improve wifi stability).
    
  • Hotfix3 [19 July]: Boot: improved init/mad2sd scripts to prevent bootloop problem for some users; ensure /system is mounted read-only. Framework: replaced wpa_supplicant & dhcpcd binaries with Samsung versions - fixes all problems with slow/unreliable wifi (re)connection.
    
  • Hotfix2b [19 July]: Framework: increased Dalvik VM heapsize to 24mb (can improve game performance and fix rare force-close problems with Market and other apps). Kernel: smartass scheduler tweak to fix TuneIn Radio distortion during sleep (please set your minimum CPU frequency back to 122Mhz & re-test); moved some kernel modules from ramdisk to /system (reclaims 5mb RAM); disabled loading of RFS modules (reclaims 5mb RAM); fixed lowmemorykiller properties to avoid unnecessary task killing; re-added compcache module. Please make sure you have version "2b", as the original hotfix2 was buggy.
    
  • Hotfix1 [16 July]: fixes call hangup bug. We were missing some Samsung RIL files.
    
  • Kernel: backported 2.6.35 KGSL & DRM drivers.
  • WiFi: now using ar6000.ko built from source; should solve sleep of death, but connecting/reconnecting is still not 100% perfect.
  • Framework: fixed incorrect cellular network signal reporting.
  • Framework: replaced all adreno200 libs with Samsung Ace Gingerbread versions.
  • Framework: removed all graphics workarounds.
  • Updated CyanogenMod source.
  • Summary: this release has significantly better graphics performance and more stable wifi.

• You are not allowed to view links. Register or Login - 10 July 2011:
  • Data wipe?: not needed.
    
  • Known issue: high battery drain and wifi sleep of death issues reported. Please install hotfix2+ to resolve.
    
  • Hotfix4b [13 July]: Kernel update: added CPU & AHB overclocking support. Maximum selectable frequency is now 768Mhz but I do not recommend using the highest value. WARNING: I am not liable for any damage that you may experience as a result of using the overclock feature.
  • Hotfix3 [11 July]: Kernel updates: added interactive, smartass CPU governors (smartass set as new default); added BFQ IO scheduler (set as new default), added ramzswap (compcache) module, CPU frequency selection fix (CPU frequency settings now selectable in Options -> CyanogenMod -> Performance -> CPU); reduced minimum CPU scaling frequency  to 122Mhz. Framework: added compcache support; enabled compcache by default & using 18% of total memory. Translation: big kernel update that should improve responsiveness & increase battery life.
    
  • Hotfix2 [11 July]: reverts kernel + ar6000 to known stable versions. Should fix wifi sleep of death issue.
    
  • Hotfix1 [10 July]: upgrades ar6000.ko module, fixes kernel battery driver - should fix wifi sleep hang and battery drain (battery was not actually draining - the driver was misreporting).
    
  • New kernel based on Samsung Ace/Mini 2.2.1 source release with better kernel config. This fixes all reboot hangs, and should also fix wifi sleep issues, give better stability & performance, and may help reduce battery drain (needs testing).
  • Upgraded all proprietary kernel modules (e.g. AR6000 wifi, NAND fsr & fsr_stl)  to latest versions.
  • Small USB tethering fix - it will refuse to allow tethering if you have UMS enabled.
  • Improved Bluetooth boot-time initialization (should help prevent cases where Bluetooth refuses to turn on).
  • Updated CyanogenMod source & other small fixes.

Framework: fixed UsbController.cpp code. This release should really fix I5508 support (but I need testers to confirm), and also fixes USB tethering for all.
    
  • Hotfix4 [4 July]: Kernel update: adds support for Europa I5508, adds CIFS kernel module (if people need to use Samba/sharing apps).
    
  • Hotfix3 [4 July]: fixes audio/call instability & framework restarts related to Bluetooth & the FM radio.

Before you ask...
I have no interest or intention to further "mod" the ROM with any kind of hacks or customizations (like custom apps, themes, Swype, etc.). My only aim is to have a 100% stable port of CyanogenMod. Any such requests will be ignored.

Known issues (any assistance on the following items is welcome)

• Bluetooth will cause a wake lock, preventing the phone from deep sleeping. Don't leave Bluetooth enabled when you don't need to use it.
• FM audio requires Bluetooth to be activated. This is how the CM7 FM app works, so please don't ask me to "fix" something that is not broken. Alternatively, you can purchase the You are not allowed to view links. Register or Login app which can activate the FM radio without the need to fully enable the Bluetooth stack.
  
• The Camera app does not properly save zoomed images at the highest resolution (WXGA). Note: the zoom function would only apply cropping to the image, as our camera does not have hardware zoom capability.
• Some users report that certain SIM cards are incompatible with CyanogenMod. Please provide a radio logcat  to help diagnose these problems.
  
• Kies will not work properly on CyanogenMod. This is not a bug - it's a feature
• Battery drains. If you don't use mobiledata at all, using the Use only 2G networks option in the Mobile network settings will significantly improve your battery life. If you use mobiledata, I recommended that you make use of the mobiledata 2G/3G switch. This downgrades the cellular network to 2G when you turn off mobile data, thus allowing battery savings without forcing you to use the slower EDGE mobiledata speed.
  
• Erratic compass. Recent releases are using OuNao's g5sensord daemon. Its behaviour is not completely accurate yet, so if you wish to revert to the proprietary memsicd daemon, run these commands:

Code: You are not allowed to view links. Register or Login

adb remount
adb shell mv /system/bin/g5sensord /system/bin/g5sensord.old
adb shell cp /system/bin/memsicd /system/bin/g5sensord

Reporting bugs:
To report issues, you must generate a bug report. Open Settings -> Device settings, and select Generate bug report. The bug report file will be saved to your /sdcard, which you can upload to the forum or to a file-sharing site.

Alternate download location: Using the GooManager application to download & install my ROMs is recommended. If you want to download via the PC, however, you can use You are not allowed to view links. Register or Login link.

• md5: 006ae3834787d8ae7a59a190d819521c
  
• Update CyanogenMod source. Highlights: fixed memory leak in Phone app; added simple caching to XML compilation; fixed render effects to ensure whole screen is refreshed when changing effect; other small fixes.
• Enhanced g5sensord & libsensors. Previously, libsensors was killing/restarting the g5sensord daemon based on sensor demand, which may have been causing minor lag when the phone returned from idle. New method keeps the g5sensord daemon running at all times, but it will now sleep or poll sensors based on a signal sent from libsensors. The result: no unnecessary battery drain, and reduced lag when returning from idle. BIG thanks to OuNao.

sensors are  not working as of now




other things are working as of now

[keywo]

I have flashed 0.7.
Problems so far:
-broken GPS
-broken sensors DO NOT FLASH IF YOU NEED SENSORS

Will update this list as I go along.

[keem]

does this rom still include codeaurora kernel ?
cuz i noticed that some after-codeaurora changes are still here but google docs is missing.

about 0.7, everything looks and works great (i mean like never before) but, like someone said, sensors are not working.  so...
accelerometer - fail
wifi - ok even ad-hoc works and connects fast but i've encountered a wakeup issue and i had to take out the battery
gps (using jp2 baseband, i'm from europe) - works fine, like 1 min to lock for the first use and 5 seconds after (using gps status and igo)
music player - using 0.6, sometimes i was unable to play music from my sd card because it was unmonted everytime i was trying to play a file. 0.7 - problem solved and like 0.6, dsp manager has been improved like, alot !
i'll test everything later and maybe i'll come with another post

anyway, good job psyke

with mad2sd off:

1. wifi does not lock after disabling, it even do not find the wifi network
2. reboot not working for the first time, needed to pull out the battery
3. after reboot wifi locks right away for the first time but after disabling obtaining ip but there is no networks in the list for several minutes and after found it lock imediatelly
4. wifi seems more stable -> leave wifi enabled
5. bad network signal, it fluctuates from full lines to less lines

36. wifi is of at start, g3 is off, turn the wifi on and my phone wifi lock imediatelly
37. phone wakes from sleep after some time
38. disabled wifi icon, have gone out of area of wifi signal for a while, wifi locks after i came back
39. left the wifi area with wifi enabled, came back with wifi icon enabled, wifi did not lock -> connecting...
40. disabled wifi icon, enabled it back  -> connecting...
41. turned off the router, turn it back on -> my galaxy connected imediately
42. turned the wifi icon off, left the area of signal and came back, turn it back on and wifi works
43. turned the wifi icon off, left the area of signal and came back, turn it back on and wifi ... obtaining ip adress but there is no my network in the list of wifi networks even i am in the same room and my comp is detecting is perfectly, after a minute it finds the network
44. left the wifi area with wifi enabled, came back with wifi icon enabled, wifi did not lock -> disconnected, scanning, connecting...
45. disabled wifi icon, enabled it back  -> scanning, connecting...

conclusions:

1. it seems that wifi driver does not disconnect properly form the network if leave the area of signal with wifi antena on.
2. i did not try the change in wifi policy -> never sleep, at the time i have never when plugged in, but the bug is not repeating as it seems now. if anybody with this bug can try to change the wifi policy to never to actually find out if this is the cause of the condition.
3. it seems that wipe out is good to be made and after done with wifi session with screen on ie. non sleep mode it is good to turn it off if you have sleep bug otherwise the phone wont turn on and the battery should be pulled out to turn the phone on again. unless both g3 and wifi are turned on.
4. it seems a lot of bugs has been corrected and it is stable but it needs same fine calibrating. guys please test the device with that rom and notify all the bugs to be corrected to make it super stable. thanks.

[avvg]

Working fine.
Camera working properly.
Not able play MP4 video, only sound is audible.
Simtoolkit not working properly.
Don't use Factory data Reset from phone settings. I had faced network problems.
This ROM seems to be more stable and no noticeable bugs found so far.
Thanks MAD team for the great effort.
