[Kernel] Alfs for WLAN and CM7-by djnilse |v09c| 19-12-2012 - XPERIA X8 Original Android Development

I started playing with the kernel and the result was surprisingly pretty good(in my opinion),so here it is Remember I'm not an expert or developer, so expect bugs and use at your own risk.
NEWS: Djnilse is making this kernel for cm7 roms.Head over to post #3 and read more.
X8_*WLAN/GDX is for GingerDX v.1-28
X8_*CM7 is new and for "standard" cm7 roms with tiwlan(wifi driver)
This kernel is based on the FreeXperia-Team's work, so a huge thank you to the best team

Bugs
-v09a :Hitachi-lcd screen cut/image-displacement.Read change log v09 for more info
-v09a-CM7 :Usb: offline charging boots phone up(use airplane mode if you want to be offline) Offline charging is working on 09c-WLAN
-??
Tips
-don't use app2sd script(system/etc/init.d/10apps2sd) when using sd-ext.My phone gets useless with dalvik cache on sd, and I have a class 6 card.Use link2sd instead to free up space, and keep apps you often use on phone.
Thanks

Note: Aroma File Manager
the newest version (v9c) includes the possibility to use aroma file manager

Intro
I've been working with alfsamsung for a while now, and together, we managed to port the CWM-Touchrecovery from Napstar to the Xperia X8 (both for cypress and synaptics)
alfsamsung still handels the developemnt, i will handle the releasing of the cm7-version, and maybe a little bit developement, I'm still learning it
What does cm7 version mean ?
so alfs kernel is generally for gingerDX and gingerDX is build from the cm hero sources, but since the x8 has own sources most roms are from build from them.
so the difference between(regarding wifi) that hero uses wlan(.ko) and x8 uses tiwlan(.ko), so wifi will not work
now with two different versions it's not a problem
anymore just take the kernel that fits your rom(gingerdx or cm7)
LibSensorPatch needs to be flashed on MiniCm and roms based on MiniCm
if your proximity sensor doesnt work you can try flashing it, it should solve it
What's new
V09c - 19.12.2012 - 20:41(GMT+1)
- read the changes in alfs changelog
and just for notice, alfsamsung is the great dev here
V09a - 13.07.2012 - 17:23(GMT+1)
- usb connection fixed, thank alfsamsung for the fast update and that he sent me the kernel so i can upload it
i don't have time to build it myself since i'm getting prepared for 3 weeks holidays
V09 - 11.07.2012 - 19:13(GMT+1)
- nothing new for the cm7 version, check alfsamsung's post for the changelog
- be sure to use the newest update.zip patch form alfsamsung's post
and dont forget the LibSensorPatch down here
V08a - 27.03.2012 - 21:13(GMT+1)
- added Eduroam support
- a small update to ext4
- fix for MiniCM7 proximity sensor with old libs of MiniCM7, check attachments
flash it with CWM and have a nice week
This time I made it with NO_FSP_CAP, the other versions was with FSP_CAP enabled, if you got errors like screen tearing, please report, or if it works just fine or is faster than before
V08-v5 - 15.03.2012 - 20:35(GMT+1)
- linked wifi driver instead of copying, should boot up a little faster
- cm9 wifi fix
V08 FIX3 - 07.03.2012 - 07:36(GMT)
- included charger in the ramdisk, so offline charging working now
V08 FIX2 - 03.03.2012 - 15:13(GMT)

Thanks, alfsamsung! Gonna test it as soon as possible.

---

Thanks, I will test it, but why anyone can't build kernel for Froyo? Froyo + dope kernel with all features and X8 will be really crazy.

This is a different driver and I can't fix it because i have synaptics.Is this a big problem for phones with cypress?
@all:How is the overclocking working?

Click to expand...
Click to collapse
but maybe cypress driver can be set with the same parameters of that fix, at least i looked ax8mt module source code and they had basically the same structure.
pd: at least for me it's a big problem and it's why i am still on froyo. Touchscreen phone's shouldn't have bugs on touchscreen hahaha
