Sapphire Dual-X R9 270 HDMI "not working" after patched FB

Hey, guys.

 

I patched my FB using this tutorial: http://www.insanelymac.com/forum/topic/303186-how-to-modification-of-amd-fb-clover-injection/

 

I usually use DVI-I on my computer and it's working 100%, goes straight to the desktop. But when I want to plug it in my TV, I use HDMI, and it's not working how it should, I need to put the computer to sleep to get video after booting up, whereas it shouldn't be behaving like this after patching the FB with Clover.

 

I'm using the Futomaki FB and FakeID injection on Clover (68101002). Remember my card is a Sapphire Dual-X R9 270 (0x68111002) not a 270X.

 

Anyone know how to fix this or why it happens? Thanks!

OK, I was made further tests. Till now, I was figured that the card is working with 3 framebuffers (Aji, Futomaki and Hamachi). Sadly, HDMI doesn't work with any injected Framebuffers, but it works with default one (ATY,AMD,RadeonFrambuffer@0)

 

If I understood well all numbers, this should be correct:

 

Connector-type number for (DVI) is 0x4

Connector-type number for (HDMI) is 0x800

 

With DSDT injector display is reported on third connector (ATY,Hamachi@2), and in situation where DSDT injector is not used it is on first (ATY,AMD,RadeonFrambuffer@0)

 

Those are basically obvious differences.

 

I could rearrange this but if I remember correct that will require AMD7000Controller.kext patching via some hexeditor, which I’m really trying to avoid.

 

In both cases sleep is working properly, which is good thing.

 

I was made also, OpenGL tests in Cinebench. Mavericks reports this card as FirePro D300, but ML 10.8.5 reports it as Pitcairn Unknown model. The better score is in ML 10.8.5, probably because it detects card properly. 

 

I really hope that the future OSX updates will fix this issue…

 So I have to edit the connectors patch to "80 00 00 00" instead of "00 08 00 00" on the HDMI line? I read the whole article but didn't understand too much, I just don't want to edit too many stuff like kext editing cause I want it to be as vanilla as possible.
