I'm perfectly happy to drop this series though, if people generally are of the opinion that this sort of firmware workaround is ill-advised. We are unaffected by it, so I certainly have no pressure to have something working here. It's my desire not to be user-hostile that motivated this patch.
IIUC you guys and Reneas are the only ones who have hardware that might be in a spot where users aren't able to update the firmware (ie, it's out in production somewhere).
I dunno if we can really keep thinking like that though. In terms of people who have devicetrees in the kernel and stuff available in western catalog distribution, sure. I don't think we can assume that that covers all users though, certainly the syntacore folks pop up every now and then, and I sure hope that Andes etc have larger customer bases than the in-kernel users would suggest.
So I'm adding Geert, though he probably saw this months ago...
Prabhakar might be a good call on that front. I'm not sure if the Renesas stuff works on affected versions of OpenSBI though, guess it depends on the sequencing of the support for the non-coherent stuff and when this bug was fixed.
ATM, I dont think there are any users who are using the upstream kernel + OpenSBI (apart from me and Geert!). Currently the customers are using the BSP releases.
That doesn't really answer whether or not you (and your customers) are using an affected version of the vendor OpenSBI? The affected range for OpenSBI itself is [v0.8 to v1.3).
Did you perhaps miss this mail Prabhakar?
Cheers, Conor.
