How to Fix DSDT using Clover (since rev. 479)
----------------------------------------------------------------
New setting in /EFI/config.plist:
ACPI:
<key>FixDsdtMask</key>
<string>0xFFFF</string>
Suggest to remove /EFI/ACPI/patched/dsdt.aml if get kernel panic.
All mask values are as below. Some patches need Method DTGP (0x0001) to work fine.
Definition of 0x00FF:
0000 0000 0000 0001 = 0x0001 = FIX_DTGP
0000 0000 0000 0010 = 0x0002 = FIX_WARNING
0000 0000 0000 0100 = 0x0004 = FIX_SHUTDOWN
0000 0000 0000 1000 = 0x0008 = FIX_MCHC
0000 0000 0001 0000 = 0x0010 = FIX_HPET
0000 0000 0010 0000 = 0x0020 = FIX_LPC
0000 0000 0100 0000 = 0x0040 = FIX_IPIC
0000 0000 1000 0000 = 0x0080 = FIX_SBUS
Definition of 0xFF00:
0000 0001 0000 0000 = 0x0100 = FIX_DISPLAY
0000 0010 0000 0000 = 0x0200 = FIX_IDE
0000 0100 0000 0000 = 0x0400 = FIX_SATA
0000 1000 0000 0000 = 0x0800 = FIX_FIREWIRE
0001 0000 0000 0000 = 0x1000 = FIX_USB
0010 0000 0000 0000 = 0x2000 = FIX_LAN
0100 0000 0000 0000 = 0x4000 = FIX_WIFI
1000 0000 0000 0000 = 0x8000 = FIX_HDA
How to use dsdt fix:
--------------------
0000 0000 1111 1111 = 0x00FF = Fix all of bit(0) ~ bit(7).
1111 1111 0000 0000 = 0xFF00 = Fix all of bit(8) ~ bit(15). Need to be 0xFF01 with method DTGP first.
You can fix dsdt for single function. Need method DTGP to work without dsdt.aml.
0000 0000 0000 1001 = 0x0009 = DTGP + MCHC
0000 0000 0010 0001 = 0x0021 = DTGP + LPC
0000 0000 1000 0001 = 0x0081 = DTGP + SBUS
0000 0001 0000 0001 = 0x0101 = DTGP + DISPLAY
0000 0010 0000 0001 = 0x0201 = DTGP + IDE
0000 0100 0000 0001 = 0x0401 = DTGP + SATA
0000 1000 0000 0001 = 0x0801 = DTGP + FIREWIRE
0001 0000 0000 0001 = 0x1001 = DTGP + USB
0010 0000 0000 0001 = 0x2001 = DTGP + LAN
0100 0000 0000 0001 = 0x4001 = DTGP + WIFI
1000 0000 0000 0001 = 0x8001 = DTGP + HDA
Or fix dsdt for multi functions. Need method DTGP to work without dsdt.aml.
0000 0101 0000 0001 = 0x0501 = DTGP + DISPLAY + SATA
0011 0001 0000 0001 = 0x3101 = DTGP + DISPLAY + USB + LAN
1011 0101 0000 0001 = 0xB501 = DTGP + DISPLAY + SATA + USB + LAN + HDA
