Intel HD Graphics / GMA 5700

I just updated to 10.6.5 today. You still need to use cpus=1 & busratio? I don't have HP notebook but I know it is known issue on HP notebook. I read somewhere at tonymac forum that someone already tried to patch APIC table but it didn't work. Sorry, I don't remember or save the link since it is long time ago. This is my APIC table if you're interested. If not, just ignore it.

Back to topic. I use Graphics Mode to set resolution to 1280x1024. It only work on external monitor since the resolution is not supported by internal monitor. I didn't noticed the IOFBCurrentPixelClock and IOFBCurrentPixelCount properties. I'll check it later. About the ROM file, are you comparing it with MacBookPro's Intel HD ROM?

Hi kizan,

Yup. I still need it. I patch the APIC table but it did not change anything. Seen other links about a possible DSDT patch, but there's no code (example) and thus I am stuck.

p.s. Mucha made the lapic.c patch available here, and said that it was a BIOS bug, but without telling where, in which ACPI table, and what the actual bug is about so there's no way of patching it.

Same here. Only 1024 x 768 availble (max) for the LCD panel. Do have higher resolution also, but never tested them. Will do later tonight. And yes I am comparing the hack against the MacBookPro. I also write tools, like the one I wrote today (dminfo.c):

To see if I can spot anything wrong.

All thanks to Christoff for providing the hint in post #181.

Update: Did connect an external monitor (@1600 x 1200 x 32) and this is what I see (snippet):

CGDisplayPixelsWide : 1600 pixels

CGDisplayPixelsHigh : 1200 pixels

CGDisplayBytesPerRow : 4096

Not good. Stuck at 1024 pixels width. This 4096 should be 6400 (1600 x 32 >> 3) !!!

p.s. IOFBCurrentPixelClock and IOFBCurrentPixelCount change (on resolution changes) for the external monitor!

@FredWst Can you boot with the newly compiled IOGraphicsFamily.kext? I can't. Get errors. Can you make a small modification in setupCursor in IOFramebuffer.cpp and see what value you get?

rowBytes = info->bytesPerRow;

+ IOLog("rowBytes: %d", rowBytes);

totalWidth = (rowBytes * 8) / info->bitsPerPixel;

bytesPerPixel = info->bitsPerPixel / 8;

You can inject a new value too. Examples:

((1024 * 32 = 32768) >> 3) = 4096

((1280 * 32 = 40960) >> 3) = 5120

((1440 * 32 = 46080) >> 3) = 5760

((1600 * 32 = 51200) >> 3) = 6400

((1920 * 32 = 61440) >> 3) = 7680

Hi

have you all seen this

http://www.insanelymac.com/forum/index.php?showtopic=216726

"lebidou's autodetection for ati, nvidia and intel

display-cfg injection added (hopefully working) "

sounds good

Will give it a try, when i have time

To see if I can spot anything wrong.

All thanks to Christoff for providing the hint in post #181.

Update: Did connect an external monitor (@1600 x 1200 x 32) and this is what I see (snippet):

CGDisplayPixelsWide : 1600 pixels

CGDisplayPixelsHigh : 1200 pixels

CGDisplayBytesPerRow : 4096

Not good. Stuck at 1024 pixels width. This 4096 should be 6400 (1600 x 32 >> 3) !!!

p.s. IOFBCurrentPixelClock and IOFBCurrentPixelCount change (on resolution changes) for the external monitor!

@FredWst Can you boot with the newly compiled IOGraphicsFamily.kext? I can't. Get errors. Can you make a small modification in setupCursor in IOFramebuffer.cpp and see what value you get?

rowBytes = info->bytesPerRow;

+ IOLog("rowBytes: %d", rowBytes);

totalWidth = (rowBytes * 8) / info->bitsPerPixel;

bytesPerPixel = info->bitsPerPixel / 8;

You can inject a new value too. Examples:

((1024 * 32 = 32768) >> 3) = 4096

((1280 * 32 = 40960) >> 3) = 5120

((1440 * 32 = 46080) >> 3) = 5760

((1600 * 32 = 51200) >> 3) = 6400

((1920 * 32 = 61440) >> 3) = 7680

Can't test anymore

I've sold my e6510, and i've bought a Macbook pro

Fred

@fmac: Link is dead. Get a Board Message. Not to mention that display-cfg is NVIDIA only and that NVIDIA is supposed to be easy. I wish I had one because that would have saved me a huge amount of time, but killed the fun too

@FredWst: Congratulations... and welcome on the other side.

Eeks. Batteries drained too much (Apple Bluetooth keyboard and mouse). Need to find spares or...

Right, but I fail to see how this is going to help us with the Intel GMA5700.

Me neither, but this is what I made of it with help of a Google translation:

He advised people in that forum "to cut firewood Intel HD" (until 10.6.6 is released) and one person asked: "How?". He then added a screenshot with selected AppleIntelHD*.kext's with the context menu open on what I believe is 'Move To Trash' (3th option).

Tomdev · November 15, 2010

Just popping in here I also have the Intel HD graphics (Dell inspiron 15r with i3), and of course my graphics aren't working properly.

But which kext of the three intelhdgraphics kexts is causing this problem (not booting anymore etc.)? and the most interesting why?

icy · November 15, 2010

Yes. You translated messages and screenshot correctly.

I don't c how that post help us... check the second screenshot, the Intel HD Graphics is in same situation as all of us

No kext is loaded, and the resolution is stuck @ 1024x768x32

P.S

dutchhockeypro I track your post since day 1 and I can say that from all what I c till now in OSX forums U r the only1 that actually did some progress....

If I can help with anything let me know... I code on .NET platform and have OSX 10.6.5 installed with Vanilla kernel - got everything working beside that damn Intel HD Graphics.

btw, have u tried the latest version of Chameleon? Its detecting the card and output a msg "Not Yet supported" and I know that u can use a ROM file with it (U said that u got the ROM from a macbook pro no?)

Fiox89 · November 15, 2010

But whit the way of yurick, Intel HG Graphics have QE/CI?

And the Nvidia 310M have QE/CI ??

yurick · November 16, 2010

There is not completed yet DSDT with seven errors. Originally it was 201! Registered 2 video cards intelHD and nVidia, with no name. Ability not have enough time now to complete this work. What should be done to fix the laptop off to disable intelHi video card or monitor connected to another card ... or wait for 10.6.6

systems profile intel pentium P6100

or we need to correct for the 4.0 compiler

Time2Retire · November 16, 2010

@naaa354: Thank you for your kind words. Still trying to get a grip on things, and it is very difficult to really do something. To make a change. Need more experienced hackers. And I am not using the original Chameleon, but Revolution tailored towards my needs. It is also a slightly faster booter (60+KB /boot file).

@yurick: If you need help with fixing your DSDT then please visit this or this topic and ask for help.

@fiox89: No. Unfortunately not.

@Tomdev: Huh? Not booting anymore? You mean having a black screen? Delete AppleIntelHDGraphicsFB.kext and recreate Extensions.mkext That should give you the boot display.

Tomdev · November 16, 2010

But which kext is causing all the problems? (I want to investigate that one a bit more with otool etc.)

Time2Retire · November 16, 2010

But which kext is causing all the problems? (I want to investigate that one a bit more with otool etc.)

I would say AppleIntelHDGraphicsFB.kext and AppleGraphicsControl.kext The latter doesn't even load here. We might need a FakeGMUX.kext for this ala fakesmc.kext by netkas.

Tomdev · November 16, 2010

but the crashes with this kext, I think they're not caused because of a piece of code which checks for a nvidia gpu, but it should be somehow related to this nvidia gpu(I mean if you check for a gpu and it isn't there you're not gonna make the system crash unless you're an evil coder).

Or is this speculation wrong and are these crashes caused by something else?

Time2Retire · November 16, 2010

but the crashes with this kext, I think they're not caused because of a piece of code which checks for a nvidia gpu, but it should be somehow related to this nvidia gpu(I mean if you check for a gpu and it isn't there you're not gonna make the system crash :mellow: unless you're an evil coder).

Or is this speculation wrong and are these crashes caused by something else?

What crashes? I don't have any crashes.

And the kext looking for NVIDIA is AppleGraphicsControl.kext Which isn't loading here. No wonder, because we don't have a GMUX device. You can add it in your DSDT, but that won't make it load. I tried that already.

You can also change Info.plist but that won't make it load either.

And just to be sure: Do you have an ATI of NVIDIA card next to the Intel HD Graphics? Do you have a BIOS (UEFI) option to select one of the cards?

I have an ATI 5470m and no option in the UEFI to select either card.

Tomdev · November 16, 2010

ok not really crashes, more hangs... when I updated to 10.6.5 it just hang.... after removing intel graphics kext it also hang so maybe it' s a problem with this laptop.

Beside the Intel HD graphics I've totally nothing... so no UEFI option either :rolleyes:

And now I get what you meant with fakeGMUX kext

fmac · November 16, 2010

@fmac: Link is dead. Get a Board Message. Not to mention that display-cfg is NVIDIA only and that NVIDIA is supposed to be easy. I wish I had one because that would have saved me a huge amount of time, but killed the fun too

Link is working again

for me "Auto resolution = Yes" is working

no need for "Graphics Mode = 1600x900x32"

Boot screen is 1600x900

OS X is 1600x900 but, only without IntelHD.kext :rolleyes:

with kext only remote screen is possible

a small step into the right direction ?

Intel HD Graphics / GMA 5700
