6970 in OSx 10.7.4 (Set to Null in ATI.c)

[4pack]

It would seem that the 6970 is working on Mac Pro but is not working on hacks at the moment. Although it appears the device id is in the ATI6000.controller kext there seems to be some issue causing the card not to come up correctly.

The card will work with the use of a helper card either onboard intel or other gpu, but then this simply initializes the primary card.

I have got it to work using Netkas package from new Macbook pro 2012 but only with helper card. A 5770.

The ATI6000.controller kext contains the device ID

It would seem there is no information about the card ports or framebuffer.

I had a look in the ATI.c Source
http://forge.voodooprojects.org/p/c...D/branches/Chimera/Release/i386/libsaio/ati.c

It would appear that the information has not been added....?

606 { 0x6718,0x0B001002, CHIP_FAMILY_CAYMAN,"AMD Radeon HD 6970",kNull},
607 { 0x6718,0x67181002, CHIP_FAMILY_CAYMAN,"AMD Radeon HD 6970",kNull},
608
609 { 0x6718,0x31301682, CHIP_FAMILY_CAYMAN,"AMD Radeon HD 6970",kNull},

and

804 { 0x6718,0x00000000, CHIP_FAMILY_CAYMAN,"AMD Radeon HD 6970 Series",kNull},
805 { 0x6719,0x00000000, CHIP_FAMILY_CAYMAN,"AMD Radeon HD 6950 Series",kGibba},

807 { 0x6720,0x00000000, CHIP_FAMILY_BARTS,"AMD Radeon HD 6900M Series",kNull},

809 { 0x6738,0x00000000, CHIP_FAMILY_BARTS,"AMD Radeon HD 6870 Series",kDuckweed},
810 { 0x6739,0x00000000, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850 Series",kDuckweed},
811 { 0x673E,0x00000000, CHIP_FAMILY_BARTS,"AMD Radeon HD 6790 Series",kNull},

where I'm guessing Null should be the framebuffer and give the correct ports for the card to work correctly?

So Atiports should be 5
Framebuffer = Gibba

Can this be fixed ? or is this not the issue ??

This now seems have been corrected in the trunk, so guess it will filter through on the next update....
