Hello,
I spotted this commit in code.vuplus.com:
http://code.vuplus.c...5bbb890733f2d00
It looks like vuzero also might support the dvbproxy feature.
Any tester?
Cheers

It wouldn't be the first time VU+ commits something to their own BSP, and "forget" to update the one they maintain for us...
Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Pro (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)
Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.
Many answers to your question can be found in our new and improved wiki.

What is the advantage of having "dvbproxy"? I never understood.

Vu+ decided to provide two sets of drivers
vuplus-dvb-modules
vuplus-dvb-proxy
The latter provides OpenGL ES and needs platform-utils.
For mysterious reasons OpenPLi was never informed about these new drivers.

I was always under the impression that the move to dvb-proxy was initiated by Broadcom, newer SoC use the "proxy" system. Apparently Broadcom has added "proxy" support for the older SoC's now too?

I am not expert but yes, this is what I did understand reading some headers around.
There is a cliient-server protocol (BCM IP) running on a custom platform, using NFS as seen (and disassembling the modules you see crypto funcs as well).
On vuxxo2 mipsel models kernel 3.13 needed this change:
CONFIG_NFS_ACL_SUPPORT=y
CONFIG_NFSD_V3_ACL=y
I don't know how much has been upstreamed by Broadcom in recent kernels.

NFS? Interesting. Maybe there abusing the NFS API to communicate between user space and kernel space, yuck. Old automounters do that to.
AFAIK the dvbproxy is a way for driver code to invoke code from user space (hence "proxy"). I am not sure why that would be an advantage, but it would enable driver developers to use e.g. ffmpeg to implement missing codecs in software, which I expect, at least HiSil practises, maybe Broadcom too. I know some Broadcom MIPS drivers use ffmpeg for DTS decoding.
