Hi,
I've being watching all the developments about the emerging tablets and I must say that all Tegra 250 devices look very interesting, although Toshiba Folio 100 already has PCB pads to add more ram... I am sure that Toshiba will add more 500Mb ram on the next Folio to give a better android 2.3 support.
Anyway, here's my question: how can I, or anyone else, recompile the Linux android kernel for Tegra 250 and place it in the FolioMod, well, I'm asking this because I remembered that these tablets are excellent for one thing that many are forgetting...
To watch digital television from a USB TV pen, well, the device has USB host support, it has Linux to manage the devices attached... What else is need ? Video 4 Linux... This is kernel built-in... So, how can I recompile the kernel to add this and other desktop usual features ? Any cons ?
Cheers.

I am interested in too, if you make any advance let me know; I am really interested in this!!!!
The process is quite straightforward.
Get the kernel source here: http://tegramid.com/wiki/Main_Page
- unzip the source and cd into the source directory
Get the current kernel config from your device:
Code:
adb pull /proc/config.gz
Unpack and rename the config file
Code:
gunzip config.gz
mv config .config
Adjust the config to your needs.
Now you need the an gcc to compile for arm, the easiest way is to checkout the android source repository (read source.android.com for instructions, actually you would only need the prebuilt toolchain)
Now add the compiler to your path environment variable
Code:
export PATH=<android-source-dir>/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/:$PATH
now you can build the kernel using
Code:
make ARCH=arm CROSS_COMPILE=arm-eabi-
Now you need to repack and flash your new kernel to the device.
An excellent article on how to prepare a new boot.img can be found here:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
After that simply create an update.zip and flash using recovery.
Note, AFAIK v4l support is already included in the current FolioMod kernel.
WOW
Really thanks, I will try asap!!
Btw according to dmesg output kernel commandline should be:
Code:
[email protected] [email protected] vmalloc=192M video=tegrafb console=ttyS0,115200n8 usbcore.old_scheme_first=1 tegraboot=sdmmc tegrapart=recovery:122000:a00:800,linux:a0e00:1000:800,loader:300:400:800,mbr:700:200:800,system:900:20000:800,cache:20900:80000:800,misc:a0900:400:800,userdata:a1f00:80000:800 boardtype=PR
weeds2000:
So, the kernel is the common Android Tegra 250, have you tried this already ?
I though this could be the thing to do, but I also thought that Toshiba had pulled a fast one by customizing the Android Tegra 250 kernel...
Hum... If this is so, I will buy an Toshiba Folio 100 lol... I hope to add many thing to the kernel... as a programmer I would love to have USB-RS232 adapters too eh eh eh... New horizons then!
I was also thinking, if not this device, the Viewsonic Viewpad 10, that has a BIOS and an Atom, an x86 architecture then, would be much easier to recompile...
It has some modifications ore extra modules.
Compiling the default kernel from the froyo-tegra tree from nvidia failed (not sure what exactly was missing, display simply switched off and it seems there was a kernel panic somewhere)
But yes compiling the kernel from the sources given at the wiki works. I'm running a slightly modified kernel at the moment compiled using the steps given above.
weeds2000:
Its common on embedded devices like most Android devices... The best thing invented is the BIOS lol... Without one, we must hard-code the kernel to map the resources to the specific hardware...
Do you recommend buying a Toshiba Folio 100 ?
Anyway, what modifications have you done (just curious) ?
I would recommend the Folio to someone that can do some modding and is able to flash custom roms to the device.
Before FolioMod the device was pretty much useless to me, but with the modifications done by dexter and the rest of us, it turned out to be a pretty good device.
However I would not order it blind because of the display. Compared to, for example the Galaxy Tab, you can clearly see why the device is that cheap. Viewing angle is really not good on this, so you may want to take a look at a store or something if this bother you or not (it's OK for me though).
Kernel modifications where
- mouse driver (to fix the bug introduced by the rotation fix, without success up to now)
- playing around with the kernel hacking options to get some performance. turning them off however prevent the wifi module to load
- adding utf8 NLS support to the kernel (also this is the default, as this is required to mount NTFS partitions with utf8 support, otherwise some files where missing or have bad encoding and could not be opend by mediaplayer/reader/whatever.
When you do the make config, in the kernel options menu do you recall seeing the video4linux ?
I'm guessing that the tablet only needs that included on the built kernel to fire up TV watching programs, the idea is to load a USB digital TV device and run any Linux TV programs. Not going to MythTV because it might have too many dependencies... and not all libraries are available to ARM...
The view angle doesn't bother me that much, as long as the screen image is flawless eh eh eh, its a media tablet, so, it should be anyway...
One more thing, that key combination to flash the device comes already from factory right? I recall seeing a similar combination on the NVidea Tegra 250 development board. Or does it need the Dexter flasher too ?
I'm new to tablets as you can see lol and I'm seeing lots of tasty looking tablets... I want one that I can use for hack in my (I wish) free time, I guess its just like most people here lol.
The Viewpad 10 is about the same price, has x86 (single core tho) and more 500MB ram and ... a BIOS ... But has pros and cons... damn why can't we have it all... I guess I will try to see some in my hands first. iPad looks great, but lacks connectivity and Apple wants money for a developer membership lol... Android is incredibly but the vendors are crooks that embed the kernel with the hardware instead of adding a BIOS... Windows Mobile is... to limited and simple to use, no console... bah... Is there was one for free I would pick that one, but they all have similar prices... The reviews show that all have pros and cons... oh well...
OK getting mythTV on the device is quite an impressive task.
As not even the c-library is the default glibc known from your desktop PC and may miss a few things here and there. (learned that when trying to port libfuse and ntfs-3g)

Whoa, CONFIG_MEDIA_TUNER and CONFIG_MEDIA_TUNER_SIMPLE on from default ?! Also V4L ?!?! what is going on here?! Is Toshiba thinking about making an docking station with a TV Tuner in it and a custom software to watch TV ?!
Edit: I was dreaming awake... I didn't noticed that you were writing about FolioMod kernel... But it would be fun if they did had added these features...
I used mythTV as an example LOL It has too much dependencies... I could try to get all the dependencies for ARM... or compile some for ARM... but it would take lots of time... TVTime looks better for Android, I'm off to see a real Folio 100 on my hands, I have lots of doubts LOL...
It also seems that radio was not forgotten, CONFIG_RADIO_ADAPTERS on... also a possible digital audio broadcast support... hum...
It could be fun if I or someone managed to get a TV Tunner on Folio, TV on camping, TV on the bed, TV everywhere !
The Android kernel seems to have fewer drivers tho... a pity...
Was anyone successful on compiling tegra 250 image for flashing board
Howto - creating a boot.img with new kernel
Note: I wrote a small guide how to repack boot.img when you have your new compiled kernel (based on http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images but modified for folio). I also included modified perl scripts and binary files needed under linux (ubuntu 10.10) for that (no need to compile tools from sdk). So that swapping a new zImage kernel instead of an old one is a question of seconds
See - Howto - unpack,edit,repack boot.img: http://forum.xda-developers.com/showthread.php?t=915808
hi guys i dont know if this is related to kernel but i would like to get the android policy jar. do you know how to do it?
thanks!
This is quite interesting topic you are discussing here.....
Can you pls gather the information abt the kernel compilation as well as image assembly so others can experiment too ?
What are chances to brick the device during tests ?
Being a linux user for some time I would be very happy to have something like
- either a custom kernel for android for playing
- or linux distribution to run on the device (as Archos 5 IT have dual boot with Linux for example)
perhaps we can gather up to produce something like it for our device ????
thanks
is possible try compiling kernel 2.6.35 for folio?? anyone has tried?
I am trying to compile and insert the CFG80211.ko module
I have built an Ubuntu VM and installed the correct codesourcery cross compiler.
I have been able to build several modules which successfully insert. (ntfs, lib80211, all three lib80211_crypt modules, all three wusb modules, uwb, veth etc etc)
however the cfg80211.ko module always fails with invalid argument.
dmesg reports :-

I have tried converting RFKILL to a module, in order to enable CONFIG_RFKILL_INPUT to yes but the compile completely fails when this is set.
I have added WIRELESS_COMPAT details in the Kconfig file but this did not help and I am now lost as to how to troubleshoot this?
Anyone have any idea on what might be missing?
If you're able to compile the modules, you should be able to compile the kernel - do the modules insmod against the compiled kernel?

Yes all the other modules I mentioned all insert fine the ones that I have compiled that dont insert have dependancies that all stem back to the cfg80211.ko that is giving me the messages in the first post.
from the documentation cfg80211 is dependant on RFKILL which is precompiled into the kernel.

Ahhh rereading your post, I see what you mean, I haven't installed the built kernel (though I did do the full build) on the phone, not entirely sure how to package it and I haven't tried to look because I really dont want to install a full kernel on the phone.
In any case I have used the default samsung config to build from fro the correct kernel.

Are you installing the kernel and modules, or just the modules? If you are just installing the modules, are you using an IDENTICAL version of gcc, with nothing changed between N<=>M<=>Y except for your rt2x00 module in the .config?
useful information would be:
Your kernel version string from the phone: uname -a
A diff of the base .config and the new .config: diff -ubw orig.config new.config
A diff of the phone's working .config and your .config.
You can generally get the .config your running kernel was compiled with from /proc/config.gz on the device. You would then need to gunzip that and compare it to your .config with the diff command above.

Are you installing the kernel and modules, or just the modules? If you are just installing the modules, are you using an IDENTICAL version of gcc, with nothing changed between N<=>M<=>Y except for your rt2x00 module in the .config?
useful information would be:
Your kernel version string from the phone: uname -a
A diff of the base .config and the new .config: diff -ubw orig.config new.config
A diff of the phone's working .config and your .config.

Unfortunately /proc/config.gz support is not configured in the samsung kernel by default therefore the file is not present. uname gives 2.6.35.7-I9100XXKH3-CL479037
And I have tried the recommended codesourcery cross compiler and one other variant of this and the results are the same.
it's a stock rom with an insecure kernel (basically a repack of the stock kernel) to allow rooting from what I can gather.
I have tried many configuration of build from the default .config and just building the top dependancy module from the default config
In this case the top of the tree is CFG80211
(rt2x00usb depends on rt2x00lib, depends upon mac80211, mac8211 depends upon cfg80211 and cfg80211 depends upon rfkill. There are also some dependencies on kernel crypto libraries which I am unclear about but should be in the kernel build)
I have found it makes no difference at all if I build lots of modules at once or just the very bare CFG80211.ko with as few options as possible. The failures are the same trying to insert cfg80211.ko. as it is whether I use busybox insmod, standard insmod or insmod from within a chroot. (in the searches I read modules can behave differently with busybox)
the only changes I made from the samsung default config is switching some debugging options off as per this thread http://forum.xda-developers.com/showthread.php?t=1123643
other than that it is a stock samsung default config for a 2.6.25.7 kernel build, as distributed in the samsung source code.
I haven't had the nerve to install the fully built kernel because the phone is a key tool for me reflashing a kernel is kind of a last resort
The attached rar file includes the default config (c1_rev02_premium_defconfig) the config used (.config) the output of diff -uwb between the two (differences.txt) and the two modules built ntfs.ko and cfg80211.ko.
file reveal ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), not stripped on both modules. (done chroot)
I use ntfs.ko as a control since it's a small module and in this build it inserts just fine. cfg80211.ko fails with the same message and dmesg info mentioned in the first post.
As I previously mentioned I did try modifying the RFKILL sections to be built as a module but when this is attempt the kernel build fails completely with the error:-
Code:
ERROR: "s3c_gpio_slp_cfgpin" [arch/arm/mach-s5pv310/c1-rfkill.ko] undefined!

Thanks for looking at this for me
Do you have a link to your kernel tree? I'd suspect that CFG80211_WEXT being enabled makes some changes in the WEXT functions that get compiled in kernel. With CONFIG_WEXT_* being =Y, your enableing CFG80211_WEXT probably made things not agree. Also, I believe the rt2x00 driver is a mac80211 one, so you'll likely need that too.
In summary, you'll very likely have to use your own kernel to get this going. At least loading the ntfs.ko answers that it's not a toolchain/source tree issue.

This error is due to another missing dependency (and the lack of proper dependency definitions in KCONFIG). You need to do:
egrep "s3c_gpio_slp_" -rsn
to find where those functions are defined, and find out why they're not being compiled. It's quite likely something like enabling rfkill for your arch/tree pulled in that c1-rfkill file (is your board a c1?) which is either not for your actual device, or dependent on something else being enabled. This is wholly based on previous experience with HTC kernel trees, where files from other Boards seemed to tag along.
I have no samsung hardware (although the GSII is on the list of what I'm considering ;-) )

I am aware I'll need other modules but they all come back to dependancy on CFG80211 so I am concentrating my efforts around that.
The link to the kernel tree is
git://opensource.samsung.com/p_497
but I have also used :-
https://github.com/GalaxySII/samsung-kernel-galaxysii
with the exact same results.
The config_wext elements are listed under the bluetooth elements, but I am firstly concerned that disabling these elements with adversely effect the standard wifi comms. which would not be acceptable even if I could package and install a fully kernel build. (which I can probably do enough research, on this site, to work out eventually, although I admit to some trepidation about this).

Ok, per:
https://github.com/GalaxySII/samsun...gt-i9100-gingerbread/net/wireless/wext-core.c
Lines: 434, 548, and 613, 653
Your kernel will have to be replaced to have cfg80211, mac80211, and rt2x00 working. There is no way around this, as that code is compiled into the kernel, and cfg80211 and mac80211 depend on those function doing more than your kernel does. There's no way around it. That's only analyzing the wext-core... there may be other differences.

Hi, good start. In fact I have, the differences in the kernel options between C6833 and C6843 (Brazilian model with digital TV) are:
Code:
47c47
< CONFIG_MACH_SONY_TOGARI_BRAZIL=y
---
> CONFIG_MACH_SONY_TOGARI_ROW=y
275d274
< CONFIG_ISDBT_TUNER_SMTEJ11X=y
325a325,327
> CONFIG_TOUCHSCREEN_CLEARPAD=y
> CONFIG_TOUCHSCREEN_CLEARPAD_I2C=y
> CONFIG_TOUCHSCREEN_CLEARPAD_RMI_DEV=y
Yes, I don't know why the Clearpad touchscreen is enabled for the C6833, but not for the C6843; I think it's just garbage (perhaps they made the togari defconfig based off honami, and corrected that when making the togari_brazil defconfig). It doesn't make any difference for me, disabling them keep the touchscreen (MAX1187) functions normal.
Well, back to the point: even when applying these differences to the ZU DooMKernel, the digital TV doesn't work. The app stays a long time in a black screen, and finally closes (FC). I investigated the kmsg and logcat, but nothing useful.
CONFIG_DVB_CORE is "m" by default. I tried insmod'ing every module in /system/lib/modules, but same result. I temporarily gave up, because I don't watch the crap they broadcast on the open TV here. But yeah, it would be good to have everything working...

I hadn't got around to diff'ing them I just noticed the DVB line and had a quick look at the brazil defconfig.
I guess there is a binary blob that is needed?
For some reason I have to include the clearpad stuff at the moment in the pimped kernel, I should dig to find out why so the kernel is a tad smaller.

Hmm very good insight about the binary blob... It's very possible. I have FTFs for the C6833 and C6843, I'll extract them and compare the file list.
I made it work!! Well, involves some manual steps, but it's a very good progress. I started by comparing the file listing in /system from stock C6833 and C6843 firmwares, and although there is no kernel blob, there ARE some files related to DTV, mostly dynamic libs (.so), some configuration, but most importantly, these two:
Code:
/system/bin/dtvsdserver
/system/bin/dtvserver
So, I insmod'ed every module related to DTV/DVB, and then started these guys... And the TV works! BUT, as soon as I quit the Mobile TV app, the process "dtvserver" is killed with a hangup signal, and opening the app again does not restart it, so I have to manually bring the dtvserver up first (otherwise the same previous issue happens, black screen and finally Mobile TV FC's).
I notice some DTV/DVB modules couldn't be insmod'ed:
Code:
insmod: init_module 'dib3000mc.ko' failed (No such file or directory)
insmod: init_module 'dib7000m.ko' failed (No such file or directory)
insmod: init_module 'dib7000p.ko' failed (No such file or directory)
insmod: init_module 'dib8000.ko' failed (No such file or directory)
insmod: init_module 'dib9000.ko' failed (No such file or directory)
insmod: init_module 'mpq-dmx-hw-plugin.ko' failed (No such file or directory)
insmod: init_module 'tuner-simple.ko' failed (No such file or directory)
But the modules are there, and they are the new ones... I don't get it why they can't be insmod'ed, perhaps something is missing from the kernel config? It could be one of the reasons.
Another thing I've been wondering, is why the DVB modules necessary for the Mobile TV are not loaded automatically, like the wlan module is, for instance. Perhaps a difference in the ramdisk? Something to investigate next.

Congrats on getting that far with the DTV, will make for a more complete device for the c6843 users that want to use custom ROMs
Any differences in udev or init.rc or whatever android uses?
Development using the GPL and GPL'd code
The GPL is a very powerful tool, as are the other OSS licences. One has to know how they are used and can/can't be enforced before publishing any code under these licences or modifying code that that been published under a OSS licence. Using a OSS licence brings with it risks and rewords, often these are one and the same.
When we do anything with Android [Linux] kernels we fall under the bounds of the GPL v2 that it is published under. Any modification to the kernel has to be published under the same licence, and we have to publish the newly modified source in a sate that can recreate the binary that you publish to the public/xda.
I'll leave you with this quote from http://programmers.stackexchange.com
...are you prepared to live by it, and let other people use what you've written, rather than just liking it because of what you can get out of it?

F2FS mount and sysfs options
Now that we have an F2FS-enabled firmware by default, I've been reading about the mount options and sysfs entries available. As many of us know, there are lots of tweaks out there for EXT4, but what about F2FS? Well, here is the official documentation from the Linux kernel:
https://www.kernel.org/doc/Documentation/filesystems/f2fs.txt
As for the mount options, I think only discard could be interesting (but it's questionable, some people say it's better to schedule a regular fstrim call instead). There are also some sysfs tunables which I think can have a noticeable impact in battery life, and performance. Testing them would require a lot of trial and error. I'm pasting them below for those who don't want to go through the full document:
Code:
================================================================================
SYSFS ENTRIES
================================================================================
Information about mounted f2f2 file systems can be found in
/sys/fs/f2fs. Each mounted filesystem will have a directory in
/sys/fs/f2fs based on its device name (i.e., /sys/fs/f2fs/sda).
The files in each per-device directory are shown in table below.
Files in /sys/fs/f2fs/<devname>
(see also Documentation/ABI/testing/sysfs-fs-f2fs)
..............................................................................
File Content
gc_max_sleep_time This tuning parameter controls the maximum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_min_sleep_time This tuning parameter controls the minimum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_no_gc_sleep_time This tuning parameter controls the default sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_idle This parameter controls the selection of victim
policy for garbage collection. Setting gc_idle = 0
(default) will disable this option. Setting
gc_idle = 1 will select the Cost Benefit approach
& setting gc_idle = 2 will select the greedy aproach.
reclaim_segments This parameter controls the number of prefree
segments to be reclaimed. If the number of prefree
segments is larger than the number of segments
in the proportion to the percentage over total
volume size, f2fs tries to conduct checkpoint to
reclaim the prefree segments to free segments.
By default, 5% over total # of segments.
max_small_discards This parameter controls the number of discard
commands that consist small blocks less than 2MB.
The candidates to be discarded are cached until
checkpoint is triggered, and issued during the
checkpoint. By default, it is disabled with 0.
ipu_policy This parameter controls the policy of in-place
updates in f2fs. There are five policies:
0: F2FS_IPU_FORCE, 1: F2FS_IPU_SSR,
2: F2FS_IPU_UTIL, 3: F2FS_IPU_SSR_UTIL,
4: F2FS_IPU_DISABLE.
min_ipu_util This parameter controls the threshold to trigger
in-place-updates. The number indicates percentage
of the filesystem utilization, and used by
F2FS_IPU_UTIL and F2FS_IPU_SSR_UTIL policies.
max_victim_search This parameter controls the number of trials to
find a victim segment when conducting SSR and
cleaning operations. The default value is 4096
which covers 8GB block address range.
dir_level This parameter controls the directory level to
support large directory. If a directory has a
number of files, it can reduce the file lookup
latency by increasing this dir_level value.
Otherwise, it needs to decrease this value to
reduce the space overhead. The default value is 0.
ram_thresh This parameter controls the memory footprint used
by free nids and cached nat entries. By default,
10 is set, which indicates 10 MB / 1 GB RAM.

I'm giving it a try - downloaded the latest sources from CodeAurora and applied to your kernel (adjusting Kconfigs, Makefiles and defconfig). The compilation stops here:
Code:
drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.c: In function ‘wlan_hdd_send_avoid_freq_event’:
drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.c:574:18: warning: assignment makes pointer from integer without a cast
error, forbidden warning: wlan_hdd_cfg80211.c:574
make[3]: *** [drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.o] Error 1
OK, so I edited wlan_hdd_cfg80211.c and changed line 574 to add an explicit cast:
Code:
vendor_event = (struct sk_buff *)cfg80211_vendor_event_alloc(pHddCtx->wiphy,
Then it passes by this point, but stops in following lines with similar errors (not even pasting here). What I noticed from these errors it that CodeAurora's sources seem to be incompatible with Sony's kernel, because for instance, the function cfg80211_vendor_event_alloc is not defined anywhere (ran a grep over all *.c and *.h files in the kernel).
Comparing with a CM11 kernel, this function is also not defined anywhere, but the prima sources are very different, they don't call it. So I thought: let's use CM11's prima sources.
Bingo!
Compiled fine, booted, and with the correspoding firmware in /system/etc/firmware/wlan/prima, WLAN came up normally after boot. :victory:
Now you mentioned something about CM11's prima sources, from what I understood they are not ideal. Is that true? Because there are CM11-based custom kernels which implement intelliplug (dependent on custom WLAN drivers), for instance.
Hope it works for you. In this case, I'll put together a more organized how-to of what I did.

great!
can you just fork my repo and shift to the branch which worked for you, then send pull request? i will investigate on the Z1...
and yes please do send the steps!
well if we get custom compiled WLAN modules properly working on custom compiled kernel for stock ROM then i can have features like intelli-plug, F2FS, AsyncFS and lots more on stock ROMs!

Well I'm still learning my way around git & GitHub, so I think it will be faster if you just reproduce the steps below:
1) Copy Prima WLAN sources from CM11-based kernel:
I copied from SlimRom's kernel source. Put the sources under drivers/staging/prima.
2) Modify related Kconfig and Makefile:
drivers/staging/Kconfig
Code:
131,132d130
< source "drivers/staging/prima/Kconfig"
<
drivers/staging/Makefile
Code:
58,59d57
< obj-$(CONFIG_PRIMA_WLAN) += prima/
< obj-$(CONFIG_PRONTO_WLAN) += prima/
3) Modify defconfig:
I'm pasting every option related to WLAN. The Prima options should appear after a "make menuconfig".

4) Include Prima WLAN firmware in kernel ZIP file:
Copy from a CM11-based firmware (I used PAC-Rom). Remember to set permissions as 644.
/system/etc/firmware/wlan/prima
Code:
WCNSS_cfg.dat
WCNSS_qcom_cfg.ini
WCNSS_qcom_wlan_nv.bin
5) Include wlan.ko in kernel ZIP file:
Actually I include every compiled kernel module, because we are using a different toolchain and they may benefit from it too. Remember that /system/lib/module/wlan.ko is a symlink, but in my test the target got updated accordingly.

Well I'm still learning my way around git & GitHub, so I think it will be faster if you just reproduce the steps below:
1) Copy Prima WLAN sources from CM11-based kernel:
I copied from SlimRom's kernel source. Put the sources under drivers/staging/prima.
2) Modify related Kconfig and Makefile:
drivers/staging/Kconfig
Code:
131,132d130
< source "drivers/staging/prima/Kconfig"
<
drivers/staging/Makefile
Code:
58,59d57
< obj-$(CONFIG_PRIMA_WLAN) += prima/
< obj-$(CONFIG_PRONTO_WLAN) += prima/
3) Modify defconfig:
I'm pasting every option related to WLAN. The Prima options should appear after a "make menuconfig".

which branch did u test this with?
also can you please upload the correct firmware (/system/etc/firmware/wlan/prima) which worked for you?

The branch from your kernel was master_kk-4.4.2. The Prima WLAN sources were, as I mentioned, from SlimRom's kernel, branch kk4.4.
I'm attaching the firmware to this post.

Wow this is very nice! Follows the same line of research I've been doing, but this is more "elegant" and in-depth, especially because of all the benchmarks and other comparisons he has done. I'll try this approach myself on my custom builds.
One thing I noticed is that we may still have to use the "hammer" approach with the find & replace of the "-O" flags in *.mk and Makefiles I've been doing, because some of them have these flags hardcoded (i.e. they don't take the value from core/combo/TARGET_linux-arm.mk or other base files). I'll tip JustArchi in his thread about it.
Hi guys, I posted this in the general android section and have had no answer, maybe some one here might know?
I'm trying to build AOSP using CM 11's device tree for togari/togari_gpe and have hit a brick wall after solving the first few make errors.
I have to errors, that I suspect are the same problem:
The first is if I just build with make I get this error:
Code:
Import includes file: out/target/product/togari/obj/SHARED_LIBRARIES/copybit.msm8974_intermediates/import_includes
Import includes file: out/target/product/togari/obj/SHARED_LIBRARIES/libmemalloc_intermediates/import_includes

#include <linux/msm_mdp.h>
^
Import includes file: out/target/product/togari/obj/SHARED_LIBRARIES/gps.msm8974_intermediates/import_includes
compilation terminated.
make: *** [out/target/product/togari/obj/SHARED_LIBRARIES/libqdutils_intermediates/mdp_version.o] Error 1
make: *** Waiting for unfinished jobs....
and if I do make bootimage I get this:
Code:
make: *** No rule to make target `out/target/product/togari/kernel', needed by `out/target/product/togari/boot.img'. Stop.
I suspect that both stem from aosp not finding the kernel source?
kernel source is at ~/dev/aosp/kernel/sony/msm8974/ and I'm building in ~/dev/aosp
I'm also trying to build vanir aosp using the same device tree and kernel and make bootimage completes fine.
Any help would be great
Yo, @DooMLoRD, @blueether @dbolivar
You guys have probably registred that Geohot (iPhone, PS3 jailbreaker) has successfully rooted the Galaxy S5 (and can now claim the $18,000 bounty), but i just read that this one-click root tool should work on any device running a pre-June 3rd kernel, i.e Android 4.4.2. The question is, does it work on the Ultra? I'm aware that it's easy to root an UItra AS LONG as the bootloader is unlocked, but this thing circumvents that part, and roots it. I think.
Are there anyone here still left on 4.4.2 that can try?

I made a thread here. It should work.

Hello everyone.
I have a Japanese S6 Edge (404SC). So I tried to install a custom rom in this phone as the support has ended. I can install the rom with no problem and it would boot up until the initial welcome screen.HOWEVER the touchscreen would just not work. So I asked the developer and he told me that the touch configs of my phone is different than the other S6’s. So can someone please explain to me how to change the touch configuration of this phone while compiling the kernel to make the touchscreen work again.BTW,I also couldn’t find any guide regarding this issue. Thank you.

You don't have to compile anything.
Built-in embedded devices, particularly touch screens, almost always require input device configuration (.IDC - plain text ) files to specify their behavior.
Input device configuration files are located by USB vendor, product (and optionally version) id or by input device name.
The following paths are consulted by stock Android in order
/odm/usr/idc/Vendor_XXXX_Product_XXXX_Version_XXXX.idc
/vendor/usr/idc/Vendor_XXXX_Product_XXXX_Version_XXXX.idc
/system/usr/idc/Vendor_XXXX_Product_XXXX_Version_XXXX.idc
/data/system/devices/idc/Vendor_XXXX_Product_XXXX_Version_XXXX.idc
/odm/usr/idc/Vendor_XXXX_Product_XXXX.idc
/vendor/usr/idc/Vendor_XXXX_Product_XXXX.idc
/system/usr/idc/Vendor_XXXX_Product_XXXX.idc
/data/system/devices/idc/Vendor_XXXX_Product_XXXX.idc
/odm/usr/idc/device-name.idc
/vendor/usr/idc/device-name.idc
/system/usr/idc/device-name.idc
/data/system/devices/idc/device-name.idc
Example of an .IDC file
Code:
# This is an example of an input device configuration file.
# It might be used to describe the characteristics of a built-in touch screen.
# This is an internal device, not an external peripheral attached to the USB
# or Bluetooth bus.
device.internal = 1
# The device should behave as a touch screen, which uses the same orientation
# as the built-in display.
touch.deviceType = touchScreen
touch.orientationAware = 1
# Additional calibration properties...
# etc...

Thank you @jwoegerbauer for your explanation.
So now to install the custom ROM where must I change these values. Like where are these files located
I'm really so sorry for asking this as I am still new to this.
@mikel05
Search the device for a file with extension idc: if not present then it got deleted when you flashed a new ROM and you're out of luck.

Actually the touchscreen works in the stock rom properly. It only doesn’t work in custom rom and kernels.
@ jwoegerbauer
Sorry for not informing earlier. My bad.
