macOS如何正确驱动集成显卡HDMI（包括视频和音频）

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。

1. #Maintained by: RehabMan for: Laptop Patches#graphics_Rename-GFX0.txt
2. # 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"
3. # sometimes there is already IGPU used for other thingsinto_all all code_regex IGPU, replaceall_matched begin IGFX, end;
4. # 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;

3、对于Haswell/Broadwell集成显卡:dsdt需要打入补丁 renaming B0D3 to HDAU (device at 0x00030000)

1. #Maintained by: RehabMan for: Laptop Patches
2. #graphics_Rename-B0D3.txt
3. # for DSDT
4. into method label _WAK code_regex B0D3 replaceall_matched begin HDAU end;
5. into definitionblock code_regex B0D3 replaceall_matched begin HDAU end;
6. # for GFX0 SSDT
7. # Note: Change your layout ID if you need something different
8. # inject "hda-gfx"="onboard-1" into IGPU (GFX0 originally)
9. into method label _DSM parent_adr 0x00020000 remove_entry;
10. into device name_adr 0x00020000 insert
11. begin
12. Method (_DSM, 4, NotSerialized)\n
13. {\n
14. If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
15. Return (Package()\n
16. {\n
17. "hda-gfx", Buffer() { "onboard-1" },\n
18. })\n
19. }\n
20. end;
21. # inject "hda-gfx"="onboard-1" into HDAU (B0D3 originally)
22. into method label _DSM parent_adr 0x00030000 remove_entry;
23. into device name_adr 0x00030000 insert
24. begin
25. Method (_DSM, 4, NotSerialized)\n
26. {\n
27. If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
28. Return (Package()\n
29. {\n
30. "layout-id", Buffer() { 12, 0x00, 0x00, 0x00 },\n
31. "hda-gfx", Buffer() { "onboard-1" },\n
32. })\n
33. }\n
34. end;
35. into device label B0D3 set_label begin HDAU end;
36. into method label SBCB code_regex B0D3 replaceall_matched begin HDAU end;

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 1366x768
0x01660004: HD4000 1600x900, 1920x1080
0x01660008: HD4000 1600x900, 1920x1080
0x01660009: HD4000 1600x900, 1920x1080
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
