Radeon R7 260x - No QE/CI/GraphicsAccel on Chameleon - Can't boot with Clover

[panickbr]

Hello everyone, it's been almost 2 weeks that I'm trying to solve this on my own, so I decided I will maybe ask for some help.

 

I got Yosemite installed on my PC, and it has worked well, boots ok, etc etc. I will try to do this in 2 "subtopics".

 

First, my PC:

 

CPU: AMD Phenom II X4 970

Graphics: Radeon R7 260x PowerColor

Motherboard: M5A99X EVO R2.0

 

(I think it's all that matters for now, I can add more info if it's needed)

 

# CHAMELEON BOOTLOADER

 

Problem is, I have a fairly unsupported graphics card (R7 260x). On the OSX86 it says you just need to add it's DeviceID to AMD8000 kext and AMDRadeonX4000 kext (0x66581002). Of course I repair caches and permissions. (I edit then through sudo vim, directly on the folder, if it matters).

 

I did it, and when I try to boot, after everything goes well, when it's supposed to show me the login screen, I get the grey screen "error".

 

My default bootflags are: npci=0x2000 dart=0 kext-dev-mode=1 -v

 

Things I tried to get past the grey screen error: 

 

GraphicsEnabler=Yes PCIRootUID=1 -> Same error.

GraphicsEnabler=Yes PCIRootUID=0 -> Same error.

GraphicsEnabler=No PCIRootUID=0 -> Same error.

GraphicsEnabler=No PCIRootUID=1 -> *Sometimes* I get my mouse on the screen (the rainbow loading cursor), but it doesn't move past this, and only happens 20% of the time (estimation).

 

I can boot normally through -x (safe-mode) bootflag and... voila! I have my graphics card recognized (AMD Radeon 8xxx Card - 2048mb), full resolution (1920x1080), computer stops being slow as hell, even terminal background transparecy works, but still no QE/CI or Graphics accel and, besides "light" stuff working normally, I get some graphical glitches, like the screen has some flickering; Finder "top bar" disappears until I put my mouse on top of it; and Chrome doesn't work at all (I get some colored lines on it instead of text/images and it's VERY slow). Not to mention that it's not optimal to work under safe mode.

 

# CLOVER BOOTLOADER

 

Well, this is much "simpler". I read somewhere on this forum (can't find it now, but I will edit here as soon as I find it) that someone managed to get my graphics card fully working using Clover through FakeID. Well, I go on, install Clover (I've tried like 10 different version, not kidding) and I can't get past a single screen:

 

"root device uuid is XXXXXXXXXXXXXXXXXXXXXXXXX

+++++++++++++++++++++++++++++++++++++++++++"

 

After these "+++++++++" the computer instantly reboots. I have a pretty big feeling that it's somehow kernel related, but I don't know much about it, still it doesn't work without caches or injected kexts. I have tried a myriad of things, lot's of boot flags combination, so if someone is willing to help me with this, I'm willing to start over.

 

I will try to mention some things (It's been a lot, and I don't remember much, as I've put my finger in almost everything I could):

 

I tried to symlink a mach_kernel; kext-dev-mode=1; FakeID; Custom kext (as on Chameleon); No caches; Safe-mode; Backup all graphic kexts; Patched DSDT.aml; Manually editing config.plist; Editing through Clover configurator;

 

FakeSMC is present on /EFI/CLOVER/kexts/10.10, as is NullCPUPowerManagement.

 

I should mention Clover worked normally on my PC with Mavericks, it's just Yosemite that can't boot.

not sure on the AMD side of things but I think you need a patch... i think nawcom makes it, ''exotic patch'' or something along those lines.

[panickbr]

Thank you for your response. But, there's no exotic patch for my graphics card. Related to AMD, it's all sorted out. this is why I didn't post it in the AMD section. Also, I just reaalized I posted on the Installation forum, instead of Post-install, sorry about that.

 

My problem is specifically getting Chameleon to boot with this R7 260x with graphics accel or getting Clover to work normally here on Yosemite (it worked 100% fine on Mavericks).

[RandomCoder]

I'm having R7 260x, but along with i5 650, and booting with Clover is smoothly. I'm using FakeID as following (0x66401002 or 0x665C1002):

<dict>
	<key>FakeID</key>
	<dict>
		<key>ATI</key>
		<string>0x66401002</string>
	</dict>
</dict>
...
<key>Graphics</key>
<dict>
	<key>FBName</key>
	<string>Futomaki</string>
	<key>Inject</key>
	<dict>
		<key>ATI</key>
		<true/>
		<key>Intel</key>
		<false/>
		<key>NVidia</key>
		<false/>
	</dict>
	<key>InjectEDID</key>
	<true/>
	<key>LoadVBios</key>
	<true/>
	<key>VRAM</key>
	<integer>2048</integer>
	<key>VideoPorts</key>
	<integer>4</integer>
</dict>

Hope it can help.
