--- Comment #6 from Tristian Celestin (tristian.celes...@outlook.com) ---
I think I understand why the following line in the 7140's dmesg appears:

[    0.139573] acpi:920: ACPI: \_SB_.PEPD: bitmask is 0x7


The _DSM in the 7140 returns the value when ARG2 is set to 0. On line 13760:

               If ((Arg0 == ToUUID ("c4eb40a0-6cd2-11e2-bcfd-0800200c9a66")))
                {
                    If ((Arg2 == Zero))
                    {
                        Return (Buffer (One)
                        {
                             0x07
                        })
                    }

while the _DSM in the 5175 returns a different value. On line 27255:

                If ((Arg0 == ToUUID ("c4eb40a0-6cd2-11e2-bcfd-0800200c9a66")))
                {
                    If ((Arg2 == Zero))
                    {
                        Return (Buffer (One)
                        {
                             0x7F
                        })
                    }
