Realtek 8723bs module for Orange Pi Prime

[alejandromunozes]

According to the official product site, the Orange Pi Prime board has Realtek 8723bs chipset, but the module (rtl8723bs) is missing in the last nightly build (Armbian_5.27.170508_Orangepiprime_Ubuntu_xenial_dev_4.11.0.img)

The official Debian desktop image (debian_desktop_xfce_prime_V0_1.img), downloaded from the Orange Pi website, has a working wifi chipset and I think It'll be nice to have a working wifi chipset in Armbian too.

Can you add this module in a future build?

Since it's an out of tree module it needs to be converted to a patch and tested, so it will take some time. Currently there are other issues for this board, so it will be at low priority unless somebody makes a pull request with required changes.

Zador, I've just fixed the build for OPiPrime few hours ago, I'm now checking for other boards under 4.11. As soon that I finish with those, I will take a look at this rl8723bs driver, at least to figure out how tedious it will be...

[zador-blood-stained]

DVFS will be the main problem for H5 boards. There are a lot of clock related fixes and patches in the orange-pi-4.11 branch, + r_i2c patches (that may need migration to sunxi-ng to apply them on Icenowy's sunxi64-4.11.y). Compared to this 8723bs should be relatively easy, and we also need to add 8189es support too for some OPi boards.

[martinayotte]

The 8189es driver is already working on OPiPC+ and OPiPlus2E with 4.11. Which other boards needs some tweaks ?

[zador-blood-stained]

8189es is different from 8189fs Orange Pi Lite, PC Plus and Plus 2E use 8189fs, Orange Pi 2, Plus and Plus 2 use 8189es and AFAIK it needs a separate driver

[martinayotte]

Yes, I know they are not the same. But I've misread your post and I don't have those boards anyway ... :smile:

Good day. zador-blood-stained commented on 7 May : "DVFS will be the main problem for H5 boards." As it seems to me DVFS works good enough on IW's 4.10(.0)-rc8 (https://github.com/Icenowy/linux/tree/sunxi64-next-20170216) after applying your DVFS patches (build/patch/kernel/sun50i-dev/unresolved/), naturally, after some minor adaptations of these patches. Is the problem (only) to transfer these patches and IW's made modifications of 4.10(.0)-rc8 to the currently used by you H5 kernel source (IW's 4.11.1, https://github.com/Icenowy/linux/tree/sunxi64-4.11.y) ? Or are there any other "underwater stones"? Excuse me for my misunderstandings of the problem.

Good day. The following work has been done in regard of DVFS for H5.

1. The patches [1] except "unresolved" were applied to the currently used H5 kernel source [2].
2. A little modification of the DVFS patches [3] has been made and some new patch files were added to them.
3. Patches from step 2 were applied to the kernel source from step 1.

As a result DVFS, in my opinion, works well enough on OPi-Prime. Tell me please how may I present the modifications that has been made - may I present some of modified and new kernel files in the form of source files but not as patches ?

This is off-topic here, but there are following requirements to get H5 DVFS in Armbian:

• wait until Armbian migrates sunxi64 branch to kernel 4.12 (or newer), where H5 support comes from upstream
• for the CPUfreq support, make use of clk notifier [1]
• for the THS and R_I2C DT entries, use sunxi-ng bindings
• adapt sunxi-ng fixes from [2] if they are required

Thanks. All of this already has been included and works good on my Opi-Prime 4.11.6 . Sorry for off-topic, but the work began with the inclusion of RTL8723bs to my OPi-Prime. I just wanted to share the results.

[zador-blood-stained]

H3/H5 dev branch was updated to 4.13. Rtl8723bs driver is now included by default, firmware will need to be added to firmware packages later.

[Tonymac32]

RTL8723bs firmwares are in the packages, added for Tinker Board.

Yes, I just didn't find required files using apt-file search so they probably are not present in the stable repository yet.
