On the Lenovo Slim 7x with Qualcomm X1 E80100, the current Windows ACPI
DSDT votes LOW_SVS (0x40) for all 7 MMCX OPP packages in the _SB.PEP0.G0MD
F-state EXIT package:

"FSTATE",
Zero,
Package (...)
{
   "EXIT",
   Package (0x02)
   {
       "NPARESOURCE",
       Package (0x03)
       {
           One,
           "/arc/client/rail_mmcx",
           0x40
       }
   },
   ...
},

Apply the same in Linux for power saving opportunity. Validated on Lenovo
Slim7x across daily workloads over 2 weeks with the internal 2944x1840
panel @ 90Hz and a 3840x2160 @ 60Hz monitor over USB-C MST DP alt.
