Will you be able to fix this problem mentioned in this thread pls? https://code.google.com/p/android/issues/detail?id=41631 its called wifi BT coexistance bug "
lets register as well here:
https://jira.cyanogenmod.org/browse/CYAN-550

last comment from CM is interesting:

"the driver doesn't appear to support BTCOEX at all at this point, this is work that'll have to be done by qcom."

extensive info about BTCOEX is here: http://wireless.kernel.org/en/users/Documentation/Bluetooth-coexistence

actual Linux driver status:
http://wireless.kernel.org/en/users/Drivers/wcn36xx
"list features that could be supported but are not yet" : "Bluetooth coexistence"


It would be very funny if CyanogenMod/Linux developers would fix this problem before Google team does.

=====
bottom line: :

probably every android device which has problem with wifi and bluetooth interoperability has Bluetooth driver lacking BTCOEX support . Linux/Android Kernel currently has no mechanism to peacefully share the frequencies.(information to verify)

idea from 2007: Linux Frequency Broker:
http://wireless.kernel.org/en/developers/FrequencyBroker

if this implemented? right now we have some devices working, some not working -

Nope, this kernel is only for AOSP-like ROMs and can't be modified to work with stock-based ROMs. You might ask DooMLoRD, if wants to port z1 to z1c, but other than that, we can only wait...

ps: @Androguide.fr : Can't wait for the new version of your kernel! F2FS and DT2W sounds awesome! Hope these can be used on our device as well ;)

F2FS is definitely doable on the Z1C as well, for dt2wake it depends if the device uses the same touch sensor driver.
Does the pen mode work for you guys as well? If it does then there are good chances dt2wake will too.

I'll try to make a new amami build tomorrow after work if I can.

Patience, mate, patience =)
We will get our custom kernel sooner or later (I as well prefer it sooner though) ;)
The difference in the activity is because @Androguide.fr owns z1, but not z1c, so no wonder that our device is lower on priority in his list -_-

how do you install the kernel? right now i'm on doomkernel for z1c. tried flashing with recovery but it fails so i tried using flashtool. i successfully got the twrp but the screen doesn't fit. i mean, it's like it's for for big device and options on twrp don't fit so i can't do any useful operations.

Yeah, that is because he made this kernel for Z1 not for Z1C, thinking that it'll work on it:eek:
anyway I'll send you a link for Pimped kernel compiled by me that'll work on our device.

    [KERNEL] Pimped Kernel (For CM-based 4.4.x Roms) [SoundControl/GPU OC/IntelliPlug/PowerSuspend...]

    OcVvKoc.png

    I do not own the Z1 Compact, but as it's very similar to the Z1 I will be supporting it as well.
    Please report whether this initial release works as expected or not

    All the kernel features are controllable through my Pimp My Z1 app, (thread here).

    Features
    • Sound Control: Faux123's GPL Sound Control 3
    • GPU OC : 200MHz / 320MHz / 389MHz / 487.5MHz / 533MHz / 600MHz frequency scaling steps (use Pimp My Z1)
    • Intelliplug: Faux123's latest intelliplug hotplugging driver with eco mode (v5.0)
    • MPDecision: showp1984's open-source & customizable msm_mpdecision hotplugging driver
    • Dynamic Fsync: Faux123's Dynamic File Sync v1.5
    • PowerSuspend: Faux123's power_suspend driver (replacing early_suspend)
    • Snake Charmer: Faux123's msm_cpufreq_limit CPU frequency limiter driver
    • CPU Boost: Faux123's CPU Input Boost module (will soon add controls for it in Pimp My Z1)
    • GPU Wake-on-touch: allows touch events to wake the GPU if it was previously in slumber
    • KSM: Kernel Same-page Merging enabled
    • exFAT: Samsung's open-source exFAT driver
    • F2FS: Samsung's F2FS nand-optimized file system support
    • CPUPower: Linaro's cpupower PM driver
    • Kernel mode NEON: NEON-accelerated XOR framework & support for NEON instructions in kernel mode
    • Overall Stats: CPU overall stats on a per-core basis
    • Compression: XZ Compressed & LZ4 compression algorithm support
    • Sched MC: Multi-Core Power Savings support
    • Sched SMT: Multi-Thread Power Savings support
    • Arch_Power: arch-specific power sched features enabled
    • Workqueue: backported from kernel 3.7, allows CPU hotplug to keep idle workers (learn more)
    • Toolchain: Built with Linaro GCC 4.8.3 toolchain from 14.02 release
    • Optimizations: Built with -O2 and many optimization flags
    • Kexec-hardboot ?: attempted to port @Tassadar's kexec-hardboot patches from the nexus 5, needs testing and confirmation that it works

    • Additional Governors:
      • Intellidemand
      • Intelliactive
      • InteractiveX2
      • SmartassV2
      • Lagfree
      • Wheatley
      • Lionheart
      • Badass

    • Additional I/O Schedulers:
      • SIO (SImple Ondemand)
      • FIOPS (Fair Input/Output Per Second)
      • BFQ (Budget Fair Queueing)

    • Additional TCP Congestion Algorithms:

    Alright, thanks a lot.
    So some iommu errors and apparently some errors with the fstab, partitions weren't mounted properly.

    I'm gonna build a stock CM kernel to see if my base sources are correct, then I'll enable the features.

    I will use CWM next build, no problem.
    But I need to find what is causing the freezes/reboots first, which is hard without a kmsg as I don't have the device.
