Actually, we are using 32 on the AMD system. So, do you think we can set this to 32 instead?I think that's ok. But are we really talking about number of SMRs or number of StreamIDs per master device here? Ie. are you just having 32 SMRs for an SMMU on your AMD system or do you have master devices which have 32 StreamIDs? If it's just number of SMRs we don't need to modify this macro.I am referring to the case where each mmu-master can have upto 32 streamID.
Crikey, how many SMRs do you have? Andreas and I have been struggling to write a decent allocator for those, so if you have any algorithms that don't require a quantum computer, we'd love to hear from you :)! Will
