Hi All,

I am trying to install AMDGPU modues in linux 4.16 with Android Nougat and I am facing following error when amdgpu.ko is loaded.

Please help me in which area the problem could be.

Is it in kernel itself or in libdrm, mesa, llvm or hwcomposer?

Hi Maurossi,

Can you help me with this? I am stuck with this from long time.

Not sure it's related, but you may have a look at this: https://bugzilla.redhat.com/show_bug.cgi?id=1562946

So you could try with kernel-4.17 [1] or kernel-4.18rc1 [2]

With latest kernels it is better to use latest Raven firmwares, you could use this device/common/firmware repo [3]

[2] https://github.com/maurossi/linux/commits/kernel-4.18rc1

Hi Mauro Rossi,

The following error when I try to compile both of your kernels.

 AR      firmware/built-in.a

  CC      arch/x86/pci/i386.o

  CC      arch/x86/oprofile/../../../drivers/oprofile/oprof.o

  CC      arch/x86/pci/init.o

  CC      arch/x86/kernel/SSEPlus_float_REF.o

arch/x86/kernel/SSEPlus_float_REF.c:1:0: error: -mpreferred-stack-boundary=3 is not between 4 and 12

 #include <linux/kernel.h>

 ^

make[2]: *** [arch/x86/kernel/SSEPlus_float_REF.o] Error 1

make[1]: *** [arch/x86/kernel] Error 2

Tried in Ubuntu host having kernel version 4.4 and 4.15 the error is same for both.

Do I need some additional packages for compiling kernel from your site?

Regards,

Shahul

No errors on my side when compiling with provided android-x86*defconfig files
and using Android Build System toolchain.

Mauro

[Mauro Rossi]

Would you like to try kernel 4.18rc1 images, to see if problem is solved?

https://drive.google.com/drive/mobile/folders/0B_OFHiIqgpSFMlk4bkhaMnAwbDA

Those images have HWCOMP=1 enabled, if you want to try drm_gralloc you need (just in those experimental iso) to edit boot cmdline and remove 'HWCOMP=1' manually.

Please provide also feedback with hwc enabled.
Thanks
Mauro

When you say Android Build System toolchain, can you elaborate what it is?

I am just using gcc4.8 which is with my Ubuntu14.04 machine.

The build instructions on android-x86 website:

cd android-x86

. build/envsetup.sh

lunch android_x86_64-userdebug

make -j4 kernel

Please just check yourself if you need to enable CONFIG_DRM_AMD_DC_DCN1_0 in android-x86_64_defconfig file

If you built the kernel with linux x86_64_defconfig, the result is unpredictable.

Hi,

I think system is not mounting with this image on my board.

See attachment.

Not getting shell also.

HI Maurossi,

Able to compile it with android build system after solving couple of compilation errors in wireless drivers.

With 4.18rc1 also no shell coming up and hanging after detecting sda and sda1 as shown in the attachment.

Do I need to change some BIOS or GRUB settings or any changes in kernel config file?

CONFIG_DRM_AMD_DC_DCN1_0 this I think we need not worry at this stage as the problem is with system mounting and console getting into live.

Regards,

Shyam

On Raven APU (AMD CPU) have you tried with x86 32 bit image?

Raven Ridge is problem even on Linux 2400G is now working, 2200G dont, you need pretty new kernels..

https://forum.manjaro.org/t/any-support-for-the-ryzen-2200g-and-2400g-for-linux/38079/41

  Oreo has only 4.9 kernel.
