Hi Janusz:
I follow your procedure (include patched your attachment).
I can generate but failing compile.
Any advise?
My environment is Ubuntu 16.04 (same with you), git the backports and 
checkout to master.

i'd used 'compat-wireless-2016-10-08' from lede-dev, to run
qca9984(PCIe) on linux-3.10.20
https://sources.lede-project.org/

i remember facing issue in 'skb_get_hash_perturb' as the symbol is not
defined & build was failing, but mac80211 in lede-dev patches the
symbol definition.
You can make verbose build to find the exact cause of build fail.

I'd also applied few minor patch on my own to support my board.

Thanks
Mani

I have ubuntu with 4.9-rc6 kernel - probably because of that works for me.
With 4.4 (ubuntu orginal kernel) also fail - don't know kvmalloc() -
seems like bug in backports ...
Best, report this to backports group :)

Re: How to integrate the latest ath10k driver into an older kernel release ?

[吳重毅]

Hi all:
I solved the problem from Steve deRosier's help. And my method as below:
Step 1: linux-next check out to latest version, backports also
checkout to master and apply ccm patch.

Step 2: generate tree by ./gentree.py --verbose --clean ~/linux-next/
~/backports-output

Step 3: modify DECLARE_EWMA(signal, 10, 8) to DECLARE_EWMA(signal,
1024, 8) in ../mac80211/sta_info.h of backports-output

Step 4: modify "skb=idr_remove(...);" to "skb=idr_find(...); if (skb)
idr_remove(...);"  in ../mac80211/status.h of backports-output

Step 5: Target linux kernel (the lower version or your specific
version ) need to be compiled first.

Step 6: export KLIB_BUILD="path/to/your_lower_linux_kernel"

Step 7: export KLIB="path/to/your/build/object" (I am about to get
*.ko, thus i point the directory to backports-output)

Step 8: make defconfig-your_choice (I am using defconfig-ath10k)

Step 9: make the backports-output and wait to compile.

My compile environment is Ubuntu16.04 with kernel 4.4 and I am porting
ath10k in linux kernel 4.11 back to linux 4.2.

I did it today:
- ./devel/backports-update-manager
- apply ccm patch from Arend (subscribe to backports mailing list -
you will see latest required patches)
- ./gentree.py --verbose --clean --git-revision next-20170310
--copy-list copy-list.ath ~/linux-next/ ~/backports-output

And backports generate/compile fine.

Re: How to integrate the latest ath10k driver into an older kernel release ?

[Chris Price]

I had similar problems doing the same thing with a 4.1 kernel. I'm not
sure if you are having the same problem without seeing the compilation
errors, but here is what worked for me:

- Used linux-stable repo
- Used the copy-list.ath file from
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/backports
- Added the following files to copy-list.ath: include/net/codel.h,
include/net/codel_impl.h, include/net/fq.h, include/net/fq_impl.h
- Ensure you compile using the same compiler as was used to compile
your kernel. Otherwise, I couldn't compile one of the arch modules and
the 'mcount' symbol couldn't be found.

YMMV

Re: How to integrate the latest ath10k driver into an older kernel release ?

[Jean-Luc Kalmus]

Hi,
How can I integrate the latest ath10k driver into Linux kernel v3.10.20 ? 

According to this wiki https://backports.wiki.kernel.org/index.php/Documentation/integration the integration requires the backports.git and linux-next.git (or linux-next-history.git or linux-stable.git) trees to be on corresponding tags.
I found that the latest tag in the backports.git tree is ‘backports-20160324’. Therefore the latest ath10k driver I can integrate is from the kernel tag next-20160324.
I used the command: ./gentree.py --copy-list copy-list  --integrate --clean  ~/linux-next-history/ ~/linux-3.10.20/

However, when I tried to integrate drivers from the linux tag next-20170309 using a backports tree on backports-20160324, that resulted in patching errors.
How to do the integration in that case ? 

The same problem occurs when using the method explained in this wiki page https://wireless.wiki.kernel.org/en/users/drivers/ath10k/backports using the ath.git tree.
