I had to change the .reg of TEGRA_SWGROUP_GPU to 0xaac to get the IOMMU

if you look at the TRM you see that 0xaa8 is basically constant, with
the SMMU translation bit hardcoded

Hi Thomas,
I have reviewed IOAPIC related change again, but the conclusion
may not be what you

So should I understand that the GPU group is for addresses without bit

That's exactly correct. And only GPUB can be programmed to be SMMU
translated.

Great, thanks for confirming!
Thierry, how do you want to address this? We could change the register
for the GPU group, or (maybe preferable if we want to reflect the actual
hardware state) add the GPUB group. I don't know if that would be easy
