filter dw_hdmi-ahb-audio.ko to kernel-modules package

Description of problem:

armv7hl kernel packages do not build with CONFIG_DRM_DW_HDMI_AHB_AUDIO=m

Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:

install recent kernel.src.rpm
enable "Synopsis Designware AHB Audio interface" (CONFIG_DRM_DW_HDMI_AHB_AUDIO=m) in config-armv7-generic
rpmbuild -ba kernel.spec

Actual results:

build will fail at depmod stage while packing kernel-core

Expected results:

full set of kernel packages build with dw_hdmi-ahb-audio.ko included

Additional info:

The resulting dw_hdmi-ahb-audio.ko depends on sound modules which reside in kernel-modules hence depmod for kernel-core packing stage will fail.
Fix this by moving dw_hdmi-ahb-audio.ko also to kernel-modules.
Applying filter-dw_hdmi-ahb-audio-to-kernel-modules.patch to filter-armv7hl.sh will do this.
Now out of the box Synopsis Designware HDMI Audio will be possible.

Fedora doesn't enable this module currently, so this isn't really a bug at the moment.  Are you requesting that we enable the module option you've specified?
Comment 2 billiboy 2016-01-03 16:29:02 EST
From this commit description "The module filters need to be updated" from [1] I got the impression it was planed to enable it again when figured out what need to be done.
I rebuild the kernel packages for a device with HDMI video interface and an imx6 SOC which has this IP on board (cubox-i).
It's a pity to have the video part available native and the sound part missing.
Since I figured out what was missing, my only intention was to share my findings as it works for me now.
My cubox-i will hopefully soon be running a mainline kernel, build from fedora kernel source package, with hardware accelerated 2D/3D support as etnaviv has started it's flight to mainline.

The patch looks okay but I'd like pbrobinson to review

Give me a couple of days I actually have a patch series that does a bunch of updates to the module filters and this is on my list as I think it's also needed for rockchip too (and hence now aarch64)

I'm also already looking at the accel 2d/3d stuff too as it should land in 4.5

Comment 6 billiboy 2016-01-05 10:22:18 EST

dw_hdmi-ahb-audio.ko is only required for the imx6 SOC dw_hdmi IP, rockchip is using different modules to support differences in the IP implementation between rockchip and frees

Oh, by the way, disable-etnaviv-generic.patch applied and linux-next etnaviv commits applied as patchset with this:
in config-local already works for me to build armv7hl kernel packages with etnaviv support.

This is also nice to have for on chip one time programmable fuse support:
Maybe also for rockchip and the others.
Comment 7 billiboy 2016-01-05 11:44:41 EST
here is a proper explanation available [1]. So only imx6 for now.

Comment 8 Peter Robinson 2016-01-17 02:02:40 EST
With the updated filter rules and DRM_DW_HDMI_AHB_AUDIO is now enabled for the next rawhide build.

ETNAVIV will happen when it lands.

Will review the other options later
Comment 9 Peter Robinson 2016-01-17 02:25:27 EST
And now various NVMEM drivers enabled. Thanks for the feedback
Comment 10 billiboy 2016-01-18 06:57:00 EST
Thanks for the consideration.
Will patiently wait for the kernel-4.5.0-0.rc1.git0.1.fc24 spin [1].

Yes, we should have etnaviv too :)
