Enable Streamline on Note 4

sid

Samsung seem to have recently released open-source kernel for Lollipop for Note 4 with r5p0 driver.

I am using a free version of DS-5 v20.1

I am following instructions from links below to build gator library and kernel with support for Streamline -

Using DS-5 Streamline with Mali on Samsung Galaxy Note 3 & 10.1

ARM Information Center   (link points you to DS5 v14 documentation but I am referring to v20 doc

I build gator.ko is along with the kernel.

After flashing the newly built kernel - when I try to run gatord on it - I hit the following error

root@treltektt:/ # gatord&

gatord&

[1] 10584

root@treltektt:/ # Unable to load (insmod) gator.ko driver:

  >>> gator.ko must be built against the current kernel version & configuration

  >>> See dmesg for more details

Looking at dmesg I see following --

<6>[ 4608.789927] [c1] MobiCore mcd: b02|VALIDATOR [ERROR]: SPID - 0x00000000 GAF structure checksum is invalid!

If needed - I can attach my .config file used to building the kernel.

I am using the gator.ko file built out of the same kernel which I have flashed onto my device - hence I dont know where this issue is coming from.

Any help in debugging this issue will be greatly appreciated.

Thanks

    I cannot say for certain which devices are affected. It may only be the Note4, or it may be all Samsung devices containing Mali-T760. Without testing each device, it is hard to say.

    Note that the issue lies with Samsung's BSP and not a direct issue with Mali hardware or software.

    It is also entirely possible Samsung may provide an OTA patch/update that will resolve this issue in the future.

    Thanks for your understanding
