First of all, you have been whitelisted now so you'll be able post anywhere in DevGurus.
Now coming to your problem/question. Bristol ridge does support HSA and I think it's working for that purpose. Regarding the ROCm support, AFAIK, the concerned team is working on testing commercial AM4 motherboards for the Bristol Ridge and Raven Ridge families of APUs. For more information related to ROCm support on your platform, please post your query here: Issues · RadeonOpenCompute/ROCm · GitHub
Also, for any other hardware/software related assistance, you can reach to our support team here: Support Forums
Bristol Ridge seems to work, at least to some degree. Do open issues on github for everything that doesn't work, as dipak suggested. Especially as ROCm 1.6 is out now.
About the ASUS A320M-C, the situation is unfortunate, but this board apparently was never intended by ASUS to be sold directly to consumers and seems now EOL, or at least progressively disappearing from their website. Blame the vendor (CSL-Computer?). There is now the A320M-C R2.0 which has full consumer support.
Thank you for your answers.
I agree with everything (even the csl assumption ).
Eventually i will have to buy another mainboard and cpu, maybe i will
get the ryzen apu, that was the plan for the future anyway.
But i will wait and not early adopt.
APU and the use of an extra dGPU when needed was planned and promised
to be working.
your friedly answers calmed me a bit. till later
Maybe I spoke too soon about the ASUS A320M-C. There is a new BIOS 0805 on the download page, maybe it includes new CPU support.
oh i gave up already,
thanks for the information.
i will have a look.
