zerconsolef / surface3-cameras Goto Github PK

This project basic https://github.com/kitakar5525/surface3-atomisp-cameras I just patched it can be built above linux version 6.0

It can be built and work(can detect device and call it),but system udev cannot detect it!

If you load the module,you touchscreen crashed immediately! If this happen,you must shutdown system(note: must shutdown,no restart because it crash unexpected and unnormally) and wait 1 or 2 min before start!

Link to issue: linux-surface/linux-surface#209

Take a look at my kernel repo. The upstreamed atomisp is currently not working.

Patches for atomisp (also contain sensor drivers):

• https://github.com/kitakar5525/linux-kernel/commits/mainline+upst_atomisp

Patches for kernel core (like regulators) (also contains patches unrelated to atomisp, maybe I need to create dedicated branch for atomisp later):

• https://github.com/kitakar5525/linux-kernel/commits/DEBUG/mainline+surface+k5

Sensor drivers are already included in my kernel tree mentioned above, but if you want to build drivers here:

make KDIR="/path/to/your/kernel_tree" ATOMISP_INC="drivers/staging/media/atomisp/include"

Current atomisp driver requires you to load sensor modules before atomisp main pci driver.

You must load this module first:

extra/atomisp_gmin_platform.ko

Here is the example:

# unload atomisp pci driver
sudo rmmod atomisp

# load drivers needed for atomisp first for insmod
# for sensor drivers
sudo modprobe media # needed for older LTS
sudo modprobe videodev
sudo modprobe v4l2_common # needed for older LTS
sudo modprobe v4l2_async # if using async_register
# for atomisp
sudo modprobe videobuf-core
sudo modprobe videobuf-vmalloc

# load atomisp drivers
sudo insmod atomisp-ar0330.ko
sudo insmod atomisp-ov883x.ko
# IIRC, modprobe works but try insmod instead if weird
sudo modprobe atomisp dbg_level=1 #dyndbg

You need a firmware file, place it to /lib/firmware/shisp_2401a0_v21.bin The firmware version should be irci_stable_candrpv_0415_20150521_0458. You can download it from intel-aero (https://github.com/intel-aero/meta-intel-aero-base/tree/master/recipes-kernel/linux/linux-yocto)

Just in case, the version and hash of firmware which I downloaded from intel-aero is the following:

$ strings /lib/firmware/shisp_2401a0_v21.bin | grep 2015
irci_stable_candrpv_0415_20150521_0458

$ sha256sum /lib/firmware/shisp_2401a0_v21.bin
e89359f4e4934c410c83d525e283f34c5fcce9cb5caa75ad8a32d66d3842d95c  /lib/firmware/shisp_2401a0_v21.bin

Note that the other version of firmware may not work.

You can find atomisp and its sensor drivers for Android (kernel 3.10) on some places:

• https://www.asus.com/us/supportonly/ASUS%20ZenFone%206%20(A600CG)/HelpDesk_Download/
• https://android.googlesource.com/kernel/x86/+/android-x86-grant-3.10-marshmallow-mr1-wear-release/drivers/external_drivers/camera/drivers/media/

Linux kernel for intel-aero also provides atomisp and its sensor drivers (up to linux 4.4):

• https://github.com/intel-aero/linux-kernel/tree/aero-4.4.x

atomisp and its sensor drivers as patch format for Linux v4.4 and atomisp firmware file:
