Subject: ignore invalid AccessType if RegionType only allows for one AccessType?
Date: Mon, 19 Jul 2004 10:53:29 +0200 [thread overview]
Message-ID: <20040719085329.GA21143@dominikbrodowski.de> (raw)
Hi!
The DSDTs of many Samsung notebooks contain one bug which forces users to
use a "DSDT override":
OperationRegion (ECR, EmbeddedControl, 0x00, 0xFF)
Field (ECR, DWordAcc, Lock, Preserve)
As can be seen in table 15-6 of ACPI spec 1.0b and in table 16-6 of ACPI
spec 2.0, TypeRegion EmbeddedControl only allows for "ByteAcc", not
"DWordAcc". iasl also says the same:
../dsdt.dsl 2660: Field (ECR, DWordAcc, Lock, Preserve)
Error 1048 - ^ Host Operation Region requires ByteAcc access
Given the fact that EmbeddedControl _only_ allows ByteAcc, how about
"ignoring" DWordAcc or any other (invalid) AccType in this case if
!acpi_strict, and "assuming" a value of ByteAcc instead?
Thanks,
Dominik
