I'm trying to do the same, for an other computer.

I don't find solution to have good information from Linux or Windows.

 

I'l do a spécial post to resume piker-alpha's work.

 

We have to understand pipe, port and attribut to have a working patch.

 

By the way, what is your computer ?

How many ports you have ?

Who works ?

For capri, dumped data base on SJ_UNDERWATER php script + Pike:

0b0066010002030200000002 ==> Platform-ID: 0b006601 | *Port: 02 | Pipes: 03 | *FBMem: 02 | StolenMemSize: 00000002 (32Mb)
000000010000006010070000 ==> FBMemSize: 00000001 (16Mb) | Vram: 00000060 (1536Mb) | BacklightFreq: 10070000 (1808Hz)
100700000000000000000000 ==> BacklightFreqMax: 10070000 (1808Hz)
000000000000000000000000
020500000004000007010000 ==> Index: 02 | *Port: 05 | *Pipe: 00 | ConnType: 00040000 | ConnAtts: 07010000 | DP
030400000004000007010000 ==> Index: 03 | *Port: 04 | *Pipe: 00 | ConnType: 00040000 | ConnAtts: 07010000 | DP
040600000008000006000000 ==> Index: 04 | *Port: 06 | *Pipe: 00 | ConnType: 00080000 | ConnAtts: 06000000 | HDMI
000000000100000040000000 ==> FB not-inused
000000000000020010c80f00 ==> *

What will work:

 

  • Changing StolenMemSize, max found: 00000006 (96Mb)
  • Changing FBMemSize, max found: 00008001 (24Mb)
  • Re-order/Index the pipes

What will NOT:

 

  • Cut-off pipes

Lets say i just want to have only one pipe/FB in this Platform-ID, and set it to primary, i modified values below, and always failed

 

  • Pipes: 01 (total FB)
  • Flush other pipes

Note:

 

- [*] full mystery

- Default Vram: 00000060 (1536Mb) (10.11) / 00000020 (512Mb) (10.10)

- Port in each FB indicate to nothing, since it completely different with ioreg values:

Index: 02 - Port: 05, in ioreg: port-number: 0x5
Index: 03 - Port: 04, in ioreg: port-number: 0x6
Index: 04 - Port: 06, in ioreg: port-number: 0x7
0b0066010002030200000002 ==> Platform-ID: 0b006601 | *Port: 02 | Pipes: 01 | *FBMem: 02 | StolenMemSize: 00000002 (32Mb)
000000010000006010070000 ==> FBMemSize: 00000001 (16Mb) | Vram: 00000060 (1536Mb) | BacklightFreq: 10070000 (1808Hz)
100700000000000000000000 ==> BacklightFreqMax: 10070000 (1808Hz)
000000000000000000000000
020500000004000007010000 ==> Index: 02 | *Port: 05 | *Pipe: 00 | ConnType: 00040000 | ConnAtts: 07010000 | DP
000000000100000040000000 ==> FB not-inused
000000000100000040000000 ==> FB not-inused
000000000100000040000000 ==> FB not-inused
000000000000020010c80f00 ==> *

* I never play with VGA / LVDS

* Got FB @2 (with HDMI cable attached) marked as active display, while only 2 port (DP & HDMI) available on my board. Dunno what port @0 is...

port in framebuffer are not port-number !!

apple always use port-number 0, 5, 6 and 7.

port in framebuffer is more a connection-number (preference order) than other.

 

i started a POC, but in french for now:

http://www.insanelymac.com/forum/topic/308152-poc-patch-framebuffer-display/

 

BTW: Framebuffer@0 is internal display for laptop.

 

Pipe are related to connector type, and port type (report, dual, single, ...)

 

i think have understand your problem, but it' not clear when i read you.

 

try kext and kernel patch, in clover:

 

Name: "name of your kext"

Find:

0b0066010002030200000002000000010000006010070000100700000000000000000000000000000000000000000000020400000004000007010000 000000000100000040000000

Replace:

0b0066010002030200000002000000010000006010070000100700000000000000000000000000000000000000000000020400000004000007010000 010500000008000006000000

Comment: "what you want"

 

It will enable framebuffer@1 and make it primary, configured as HDMI port.

Your display port still untouched.

 

Cheers,
