North bridge support!

Slice · February 1, 2008

North Bridge has PCIClass=060000 also known as

PCI-CPU Bridge

Host controller

AGP host controller

Yes! We need it!

Looking into MacBookPro I found

	| | +-o AppleACPICPU  <class AppleACPICPU, registered, matched, active, busy 0, retain count 7>
| |   | {
| |   |   "IOCPUID" = 0x38b5c80
| |   |   "IOCPUNumber" = 0x0
| |   |   
| |   +-o ACPI_SMC_PlatformPlugin  <class ACPI_SMC_PlatformPlugin, registered, matched, active, busy 0, retain count 8>
| |	   {
| |		 "IOMatchCategory" = "IODefaultMatchCategory"
| |		 "CFBundleIdentifier" = "com.apple.driver.ACPI_SMC_PlatformPlugin"
| |		 "MCHThrottleArray" = 
| |		 "IOPropertyMatch" = {"IOCPUNumber"=0x0}
| |   |   
| |   +-o pci8086,27a0@0  <class IOPCIDevice, registered, matched, active, busy 0, retain count 8>
| |	 | {
| |	 |   "compatible" = <"pci8086,7270","pci8086,27a0","pciclass,060000">
| |	 | }
| |	 | 
| |	 +-o AppleSMCPDRC  <class AppleSMCPDRC, registered, matched, active, busy 0, retain count 4>
| |		 {
| |		   "IOMatchCategory" = "IODefaultMatchCategory"
| |		   "IOClass" = "AppleSMCPDRC"
| |		   "IOProviderClass" = "IOPCIDevice"
| |		   "IONameMatched" = "pci8086,27a0"
| |		   "CFBundleIdentifier" = "com.apple.driver.ACPI_SMC_PlatformPlugin"

So instructions:

1. Find VendorID/DeviceID of your North Bridge

ioreg -l | grep 0600

2. My result

| | "compatible" =

3. Edit info.plist into

IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/

4. At the bottom you find

		<key>AppleSMCPDRC</key>
	<dict>
		<key>CFBundleIdentifier</key>
		<string>com.apple.driver.ACPI_SMC_PlatformPlugin</string>
		<key>IOClass</key>
		<string>AppleSMCPDRC</string>
		<key>IONameMatch</key>
		<string>pci8086,27a0</string>

5. Edit the name.

6. Don't forget to delete extensions cache.

7. Reboot

Be careful. It is not for all!

Look also about South bridge support

If stars are light on thou it is necessary for someone :rolleyes:

1. It makes PCI-CPU bridge. May be for DMA transactions.

2. AGP host controller.

I dunno the theory so deep.

if anyone has more then 1 controller with the same class he must choose only one with

DeviceNumber=0

It is here

Quick question... If there are separate threads for North and South bridges, won't you confuse newbies? :rolleyes: And won't info get out of sync?

Anyhow, though I can't get my south bridge out of "compatible" mode (see that thread), I seem to not need to modify this Info.plist...

| |   | |   "IOPCIExpressLinkCapabilities" = 34683921
| |   | |   "class-code" = <00040600>
| |   | |   "compatible" = <"pci10de,3e9","pciclass,060400">

| |   | | }

Or is it possible that I edited the wrong plist (or part of it) earlier? (Again questioning the wisdom of 2 threads…)

Dense · February 1, 2008

Nice find.

What do you notice is fixed when making this change (I assume it solves the SMC errors on a -v boot).

For those that it makes a difference to, can you please post the PCIID of the memory controller you added. It will help with a project I am working on.

You are right. It will be better to join these threads. I dunno how. Moderators?

You found PCIE bridge

I'd like to blame it on middle-of-the-night brainfarts. But, I simply pasted the section with the exact match for "060000". And that happened to only be acpi-reg that matched... Does this mean I have no north bridge?

2590 Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller

For 2641 its the LPC bridge. Which is why its PCI Class 06 subclass 01 (isa based)

The problem is I have not seen any impact on adding this (memory controller) to the plugin. This has nothing to do with my pc, can anyone confirm it improves SOMETHING?

I really don't see your north bridge. How it possible?

What is your configuration?

Ups-s, did you use Paulicat AppleSMBIOS? It may explain why you see not all devices.

Did you see at your ioreg that ACPI_SMC_.. connected also to CPU? (as in topic)

kernel panic happened inside method AppleSMCPDRC::Start (I was expected on probe, but...)

it reports "unrecognized controller type"

which I believe (and I've seen some hardcoded text strings inside ACPI_SMC...)

due to mismatch with 27d0 identities.

patch might be a good idea, also SMBus isn't a complex I2C bus protocol

however, due to latest reading IONDRVSupport code, found NUB name could be important also
