聊聊如何正确驱动集成显卡HDMI（包括视频和音频）
必备条件：
1、必须使用AppleHDA驱动声卡（仿冒、clover、applealc都可以的），使用voodoo驱动声卡应该不行的。
2、dsdt或者ssdt中关于集成显卡的gfx0改为IGPU。

# Note: Most DSDT/SSDTs use GFX0 for the integrated graphics device,# but there are few renegades that use VID or AGP1.# If your DSDT uses VID or AGP1 instead of GFX0, see the # alternate patch “Rename VID/AGP1 to IGPU”
# sometimes there is already IGPU used for other thingsinto_all all code_regex IGPU, replaceall_matched begin IGFX, end;
# rename GFX0 -> IGPU for better power managementinto_all all code_regex GFX0. replaceall_matched begin IGPU. end;into_all all code_regex .GFX0 replaceall_matched begin .IGPU end;into_all all code_regex sGFX0, replaceall_matched begin IGPU, end;into_all all code_regex (GFX0 replaceall_matched begin (IGPU end;into_all all label GFX0 set_label begin IGPU end;into_all all label _SB.PCI0.GFX0 set_label begin _SB.PCI0.IGPU end;into_all all label \_SB.PCI0.GFX0 set_label begin \_SB.PCI0.IGPU end;into_all all label _SB.PCI0.GFX0.DD02 set_label begin _SB.PCI0.IGPU.DD02 end;into_all all label \_SB.PCI0.GFX0.DD02 set_label begin \_SB.PCI0.IGPU.DD02 end;into_all all label ^^^GFX0 set_label begin ^^^IGPU end;into_all all label ^^GFX0 set_label begin ^^IGPU end;into_all all label ^GFX0 set_label begin ^IGPU end;
复制代码
3、对于Haswell/Broadwell集成显卡:dsdt需要打入补丁 renaming B0D3 to HDAU (device at 0x00030000)
#Maintained by: RehabMan for: Laptop Patches
#graphics_Rename-B0D3.txt
# for DSDT
into method label _WAK code_regex B0D3 replaceall_matched begin HDAU end;
into definitionblock code_regex B0D3 replaceall_matched begin HDAU end;
# for GFX0 SSDT
# Note: Change your layout ID if you need something different
# inject “hda-gfx”=”onboard-1” into IGPU (GFX0 originally)
into method label _DSM parent_adr 0x00020000 remove_entry;
into device name_adr 0x00020000 insert
begin
Method (_DSM, 4, NotSerialized)
{
If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }
Return (Package()
{
“hda-gfx”, Buffer() { “onboard-1” },
})
}
end;
# inject “hda-gfx”=”onboard-1” into HDAU (B0D3 originally)
into method label _DSM parent_adr 0x00030000 remove_entry;
into device name_adr 0x00030000 insert
begin
Method (_DSM, 4, NotSerialized)
{
If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }
Return (Package()
{
“layout-id”, Buffer() { 12, 0x00, 0x00, 0x00 },
“hda-gfx”, Buffer() { “onboard-1” },
})
}
end;
into device label B0D3 set_label begin HDAU end;
into method label SBCB code_regex B0D3 replaceall_matched begin HDAU end;
复制代码
4、dsdt中，对于HDAU、IGPU、HDEF三个装备注入相同的”hda-gfx” = “onboard-1” or= “onboard-2”
5、对于Haswell/Broadwell集成显卡，dsdt中HDAU和HDEF注入的layout id要一致。
6、对于Haswell集成显卡还要安装rehabman的FakePCIID.kext和FakePCIID_Intel_HDMI_Audio.kext
7、最重要的一点是要对fb（kext）打入恰当的补丁，即要修改连接类型（00 04 00 00）为（00 08 00 00）匹配物理连接，此处修改fb结合自己的ig-platform-id。苹果的设备大多采用DP连接（00 04 00 00），我们大多数笔记本采用HDMI（00 08 00 00）连接，如果你的是DP连接无需修改fb。
ig-platform-id:集成显卡注入的此属性有以下对应关系
0x01660003: HD4000 1366×768
0x01660004: HD4000 1600×900, 1920×1080
0x01660008: HD4000 1600×900, 1920×1080
0x01660009: HD4000 1600×900, 1920×1080
0x0a260006: HD4400/HD4600/HD5000
根据自己集成显卡注入的ig-platform-id结合以下信息，选择正确的补丁打入clover或者二进制文件
