Slice Posted January 31, 2008 Share Posted January 31, 2008 Why it is needed? Else you may have slow down a whole system because of interrupts treatment. 1. Type in terminal ioreg -l | grep 060100 2. You see a string like this one. This is a VendorID and DeviceID of your South Bridge | | | | "compatible" = 3. Write the name into info.plist in AppleLPC.kext or AppleACPIPlatform/plugins/AppleACPILPC.kext 4. Delete kext cache and reboot. 5. Enjoy faster computer! My result | | | | | | | +-o AppleACPILPC <class AppleACPILPC, !registered, !matched, active, busy 0, retain count 4> | | | { | | | "IOMatchCategory" = "IODefaultMatchCategory" | | | "IOClass" = "AppleACPILPC" | | | "IOProviderClass" = "IOPCIDevice" | | | "IONameMatched" = "pci1002,434c" | | | "CFBundleIdentifier" = "com.apple.driver.AppleACPILPC" | | | "IONameMatch" = ("pci8086,27b9","pci8086,27bd","pci1002,434c") | | | "IOProbeScore" = 0x0 | | | } Look also about North bridge support http://forum.insanelymac.com/index.php?showtopic=85012 Link to comment Share on other sites More sharing options...
ole2 Posted January 31, 2008 Share Posted January 31, 2008 Why it is needed? Else you may have slow down a whole system because of interrupts treatment. it's time to start collecting PCIID's compatibility list and then to report to major osx86 maintainers (jas, kalyway, macdotnub, tubgirl, etc) to include fixed kext to their future dists.

Krazubu Posted January 31, 2008 Share Posted January 31, 2008 thx for the tip Slice, For ICH8, I added : pci8086,2810 Didn't notice any difference tho, could you give some more infos about what it does ? Link to comment Share on other sites More sharing options...
ole2 Posted January 31, 2008 Share Posted January 31, 2008 thx for the tip Slice, For ICH8, I added : <string>pci8086,2810</string> Didn't notice any difference tho, could you give some more infos about what it does ? it's a very good feedback already. have you noticed any graphics acceleration? OpenGL test speedup's? Link to comment Share on other sites More sharing options...
lewellyn Posted January 31, 2008 Share Posted January 31, 2008 This sounded like a neat trick, so I added pci10de,3e0 for my nVidia nForce430 board. But, I still get the following: | | | "compatible" = <"pci103c,2a5c","pci10de,3e0","pciclass,060100"> Since you didn't say which of the values should be used, I went with my gut that the 10de value was correct… If my gut's right, we can say that pci10de,3e0 is pointless to add to the plist. (The "name" value backs up my gut…) In case it's useful: | | +-o LEG0@1 <class IOPCIDevice, registered, matched, active, busy 0, retain count 15> | | | { | | | "device-id" = <e0030000> | | | "vendor-id" = <de100000> | | | "IOName" = "pci10de,3e0" | | | "subsystem-vendor-id" = <3c100000> | | | "Power Management protected data" = "{ theNumberOfPowerStates = 3, version 1, power state 0 = { capabilityFlags 00000000, outputPowerCharacter 00000000, inputPowerRequirement 00000000, staticPowe$ | | | "acpi-path" = "IOACPIPlane:/_SB/PCI0@0/LEG0@10000" | | | "acpi-reg" = <00080000> | | | "reg" = <0008000000000000000000000000000000000000> | | | "revision-id" = <a2000000> | | | "IOPCIResourced" = Yes | | | "class-code" = <00010600> | | | "subsystem-id" = <"\*"> | | | "Power Management private data" = "{ this object = 02c46500, interested driver = 02c46500, driverDesire = 0, deviceDesire = 0, ourDesiredPowerState = 2, previousRequest = 2 }" | | | "compatible" = <"pci103c,2a5c","pci10de,3e0","pciclass,060100"> | | | "name" = "pci10de,3e0" | | | } Link to comment Share on other sites More sharing options...

toadspit Posted February 6, 2008 Share Posted February 6, 2008 Added my IXP200 in AppleACPILPC (0x1002 434c). Maybe a relevant speed improvements in Disk sequential write (tested with with XBench, was 20.36 Mb/s, now is 62.76). But other results remain the same. Does it make sense?

derailed_spark Posted April 13, 2008 Share Posted April 13, 2008 Hi ! Am I doing something wrong ? I did what the tutorial said : marius-petrius-macpro31:~ Marius$ ioreg -l | grep 060100 | | | | "compatible" = <"pci152d,753","pci8086,27b9","pciclass,060100"> Then went to Info.plist in AppleLPC.kext but "pci8086,27b9" was already present. Same thing here : AppleACPIPlatform/plugins/AppleACPILPC.kext . There should something else I should so ? Thank you ! Link to comment Share on other sites More sharing options...
