Dell Precision 7530: HDMI Port issue

Recommended Posts

I had a quick look at your config file, this being all that you posted. I am quite surprised by the amount of SSDT tables you inject, especially those labelled "xxx7080MT" but that's probably nothing todo with loss of HDMI output.


Looking at the graphics properties you inject, i.e.:


I can't help wondering why you'd inject properties to patch connector con1 (the usually physical port for HDMI) but disable such patching (framebuffer-con1-enable set to 0). Also, you appear to patch the flags of all connectors. To what purpose?


As a reminder, default properties of CFL framebuffer 0x3EA50009 are (C.f. Whatevergreen user manual) :

ID: 3EA50009, STOLEN: 57 MB, FBMEM: 0 bytes, VRAM: 1536 MB, Flags: 0x00830B0A
TOTAL STOLEN: 58 MB, TOTAL CURSOR: 1 MB (1572864 bytes), MAX STOLEN: 172 MB, MAX OVERALL: 173 MB (181940224 bytes)
Model name: Intel HD Graphics CFL CRB

Mobile: 1, PipeCount: 3, PortCount: 3, FBMemoryCount: 3
[0] busId: 0x00, pipe: 8, type: 0x00000002, flags: 0x00000098 - ConnectorLVDS
[1] busId: 0x05, pipe: 9, type: 0x00000400, flags: 0x000001C7 - ConnectorDP
[2] busId: 0x04, pipe: 10, type: 0x00000400, flags: 0x000001C7 - ConnectorDP
00000800 02000000 98000000
01050900 00040000 C7010000
02040A00 00040000 C7010000


If changing the connectors' flags is required than you would obviously need to enable such patching, failing what, the default settings are applied.
