Hi,
Thank you for your patch. This has already come up but no acceptable patch has emerged since. Please see this thread for what needs to be done if you want to provide one (or maybe Shyam already has one which has just not been sent out yet):
https://lore.kernel.org/platform-driver-x86/3b224c62-a1d8-41bd-aced-5825f5f2...
(Since this dram size is on an init path that always needs SMU version, the SMU version can just be called by the init unconditonally rather than adding more of this lazy initialization everywhere).
Thanks for pointing me to that thread. I think Shyam/AMD can come up with a better long term solution, but it may be worth pushing this patch through for a couple reasons: 1. Probing of the driver currently fails on STB enabled systems with a Mendocino SoC. A slower boot time is better than the driver failing to load IMO. 2. This patch only affects Mendocino SoCs, and was a suggested solution from Mario in the thread you mentioned.
That said, I can also just disable STB for now...
