Seeing how it interfaces to a suitable mesa card for control i/o would be 
next, but ATM I'm up to by butt in getting this 6040 gantry working. I 
think it may be possible to use a 7i90HD + a triplet of 7i42TA's if 
enough gpio pins can be found to build a parport. The driver we have for 
the pi would need pretty heavy mods to translate that SPI interface to 
something usable on the rock64. The includes are a mess, and Bertho made 
sure it would not run on anything but the pi-3b.

Keep me posted please, on the list.

Thanks Alan.

Re: [Emc-users] Mali Drivers are Open Source Now

Gene,

I just completed building Linux-4.19.25-rt16 (PREEMPT_RT) for the Pine64 A64+. 
It was relatively speaking a piece of cake. They are now using the mainline 
kernel for the Pine64 A64+. So it was just download the mainline kernel sources 
for 4.19.25 and the Preempt_rt patches, apply them, make the oldconfig then 
make menuconfig. Setup preempt_rt and compile. The biggest problem was figuring 
out what commands to use with the Makefile and the install commands. The 
directories that others have used seem to have changed. So insuring that I 
created the appropriate symbolic links was a little worrisome.  But once I had 
it all set up, it booted correctly the very first time.  I ran cyclictest and 
it reported an average latency of about 8uS, with a worst case of about 63uS. 

I don’t have a Rock64 or a RockPro64 yet but my guess is that it wouldn’t be 
too difficult either. My understanding is that they now both use the mainline 
kernel. Once I can build a preempt_rt kernel for the RockPro64, I’ll let you 
know what is involved.

My understanding is that the Mali drivers are/were a work-in-progress. I don’t 
know where they are in terms of current usability.

There are a few Allwinner SOC's out that use Mali. In fact the focus of
the open Mali support is for the latest ARM SOC's that use Mali.

Typical, too little, too late. The rock64 is probably sold out 6 months 
ago, and the rockchip-pro has replaced it. But haveing bought the 
rochchip koolaid, I'll not waste any more $ until they are willing to 
release some of the build tools.  But so far, those have been top secret 
and apparently proprietary, questions ignored, so I've not been able to 
do anything with what acts like a fine & 20x speedier rpi3, with 4GB of 
ram for 10 bucks more than the rpi kit.  So now its me with the wait and 
see attitude.
