Yes, this is correct. I'd like to added L2 data cache lines are 128 on GFX9.4.3 as well, but we are pulling cache setup information from the hardware-provided config information. As far as I know, that hardware-defined config information doesn't include cache line size, and I didn't want this patch to re-add a bunch of hand-written tables just for that. I think handling cache line size for such devices is currently TBD.

The Carrizo change was intentional. I think our reported size here has been wrong, based on my reading of the hardware RTL. Not a huge thing, but since I was here I figured it was better to report things correctly. :)
