About PCIE MHI driver build question!

[桂永林]

Hi,
   I had got a Qualcomm MHI PCIE driver which had released on kernel_xiaomi_sm8150/drivers/bus/mhi/ path. But I can't build the driver and the kernel. If someone can help me give me a guide about how to build the MHI driver?
   I use bellow command to clone the project:
      git clone -b https://github.com/Demon000/kernel_xiaomi_sm8150/tree/lineage-17.0
   The MHI driver located at kernel_xiaomi_sm8150/drivers/bus/mhi/ path.
Thanks!
Opera

Hi,

This is the friendly email-bot of Greg Kroah-Hartman's inbox.  I've detected that you have sent him a direct question that might be better sent to a public mailing list which is much faster in responding to questions than Greg normally is.

Please try asking one of the following mailing lists for your questions:

  For udev and hotplug related questions, please ask on the
  linux-hotplug@vger.kernel.org mailing list

  For USB related questions, please ask on the linux-usb@vger.kernel.org
  mailing list

  For PCI related questions, please ask on the
  linux-pci@vger.kernel.org or linux-kernel@vger.kernel.org mailing
  lists

  For serial and tty related questions, please ask on the
  linux-serial@vger.kernel.org mailing list.

  For staging tree related questions, please ask on the
  devel@linuxdriverproject.org mailing list.

  For general kernel related questions, please ask on the
  kernelnewbies@nl.linux.org or linux-kernel@vger.kernel.org mailing
  lists, depending on the type of question.  More basic, beginner
  questions are better asked on the kernelnewbies list, after reading
  the wiki at www.kernelnewbies.org.

  For Linux stable and longterm kernel release questions or patches to
  be included in the stable or longterm kernel trees, please email
  stable@vger.kernel.org and Cc: the linux-kernel@vger.kernel.org
  mailing list so all of the stable kernel developers can be notified.
  Also please read Documentation/process/stable-kernel-rules.rst in the
  Linux kernel tree for the proper procedure to get patches accepted
  into the stable or longterm kernel releases.

If you really want to ask Greg the question, please read the following two links as to why emailing a single person directly is usually not a good thing, and causes extra work on a single person:
	http://www.arm.linux.org.uk/news/?newsitem=11
	http://www.eyrie.org/~eagle/faqs/questions.html

After reading those messages, and you still feel that you want to email Greg instead of posting on a mailing list, then resend your message within 24 hours and it will go through to him.  But be forewarned, his email inbox currently looks like:
	912 messages in /home/greg/mail/INBOX/
so it might be a while before he gets to the message.

Thank you for your understanding.

Hi Opera,

Unfortunately that Github URL relates to a fork of an earlier mainline kernel,
the driver you refer to was added in that fork and not the mainline kernel. So
it's unlikely anyone here will know anything about it. I'd recommend you find
out who added that driver or who can provide support for that Github fork.

The mainline kernel does appear to have support for PCI for the SM8150-mtp,
see if arch/arm64/boot/dts/qcom/sm8150-mtp.dts fits your needs.

Thanks,

Andrew Murray
