The acpidump is already up -- BIOS is still F.05 (same as when I captured it on 8E41), so a fresh dump would be byte-identical to what I already have; no need to redo it. Full acpidump + decompiled SSDT23 (the table with the NPCF device) is attached to my earlier comment on the NVIDIA issue: https://github.com/NVIDIA/open-gpu-kernel-modules/issues/1162#issuecomment-5779711336 Same topology as board 8D40 from that issue: NPCF sits under \_SB as a peer of the GPU rather than as its PCIe child, which is why the open kernel module's NPCF binding misses it and Power Management Object stays N/A. That explains why >50W Dynamic Boost never works here, but it's a separate mechanism from the 25W/65W split on the 65W charger -- PMO is N/A in both states, so it can't be what's flipping that. Happy to attach the raw acpidump/ssdt23-acpi.zip directly to this thread instead of linking out, if that's easier for you to work with -- just say the word. Thanks for flagging the missing Signed-off-by on the other 8E41 patch too.
