Brett Whinnen Posted April 19, 2010 Share Posted April 19, 2010 Yes have the original locations in one of my previous DSDT's where I put SSDT in there as well. I wanted to see if they are loaded into the same spot or if we need to modify the addresses they are referenced from based on where they are loaded if we do it via DropSSDT=Yes. I'm just trying things from a different angle from the bits I was looking at yesterday... The thing of note and I was playing with this all yesterday is that yes we get the LPC loaded, as we have a pci8086:2815 which is exactly what a MacBookPro3,1 has I've yet to locate a lspci -nn output from a MacBookPro4,1 or a ioreg for that matter. But even though the LPC kext is loaded it is not properly initiialized, which means the C-states will not be started (regardless of whether we have them loaded or not). I ended up changing the device ID of the LPC yesterday to a number of different ones, even so far as trying to set it to the pci10de:0aae which is the LPC for a MacBookPro5,1 that most of us use (mainly due to P-States number issues). One thing I couldn't do above was to set the vendor from 8086 to 10de, so will investigate further on that one. The other option I'm looking at is to calculate up 10 p-states to allow the MacBookPro4,1 to load without modifying the resource under ACPI_SMC_PlatformPlugin to be 6 p-states...

ab___73 Posted April 20, 2010 Share Posted April 20, 2010 Yes have the original locations in one of my previous DSDT's where I put SSDT in there as well. I wanted to see if they are loaded into the same spot or if we need to modify the addresses they are referenced from based on where they are loaded if we do it via DropSSDT=Yes. I'm just trying things from a different angle from the bits I was looking at yesterday... Hi, The M1530 has 1 "visible" SSDT located at 0xDFE7217E, this is ACPI table 7. This SSDT table then loads the "invisible" SSDT tables using the array of memory locations per my previous post. Extract from the XSDT dump: [024h 036 8] ACPI Table Address 0 : 00000000DFE7389C [02Ch 044 8] ACPI Table Address 1 : 00000000DFE73B00 [034h 052 8] ACPI Table Address 2 : 00000000DFE73C00 [03Ch 060 8] ACPI Table Address 3 : 00000000DFE73BC0 [044h 068 8] ACPI Table Address 4 : 00000000DFE73C9C [04Ch 076 8] ACPI Table Address 5 : 00000000DFE73200 [054h 084 8] ACPI Table Address 6 : 00000000DFE737C0 [05Ch 092 8] ACPI Table Address 7 : 00000000DFE7217E When using the DropSSDT=yes boot option the loading of the "visible" SSDT table is skipped, so the OS never sees any of the SSDT tables. I've confirmed this by modifying the boot file to debug and output the "visible" SSDT memory address locations. I've attached the "debug" chameleon boot file it's based on RC4 source code (again thanx to the chameleon team for releasing sources). Backup you existing bootfile: sudo cp /boot /boot.bak then extract and copy the extracted boot file to your / directory. Once you have seen what you need to see restore your boot file sudo cp /boot.bak /boot Please only use this if you know what you are doing. Hopefully this helps someone.

I've been thinking about the c-state addresses as well. I've been toying with Andy V's branch of Chameleon which lets you load the SSDT tables individually. I'd had no success with another platform on which I had working c-states with the SSDTs embedded in the DSDT. I was getting the same LPC error with separate tables that we get on the m1530 with SSDTs embedded and it got me wondering. I've since found out that if you don't load embedded SSDTs you have to change the addresses they are expected at, see the thread HERE. Planning on digging some more this weekend.

Brett Whinnen Posted April 21, 2010 Share Posted April 21, 2010 I've been doing some tidying up on the DSDT, mainly cosmetic changes to match names of devices to those from the MBP5,1. But that got me thinking, the MBP5,1 uses an nVidia based main board, complete with MCP79 controllers etc. I was also looking at the MBP3,1 and it is closer, in fact it uses the very same LPC controller as ours and a great deal of other devices match up in both name and address. So what I want to find now is the ioreg output (prefer a .ioreg file but a .txt will do) and DSDT from a MacBookPro4,1. If anyone has seen one in their travels or can get hold of one please pass them onto me. I've seen almost every model but not that one! Most annoying.

CalaverX11 Posted April 21, 2010 Share Posted April 21, 2010 Having a problem here. This process seems to work about 90% of the way on the Dell Precision M4400 (similar configuration to the XPS M1530). The RIGHT side USB ports on my machine are non-functional, which also seems to have taken out the Dell Wireless 370 card (was using DellBluetoothHCI.kext), both of which worked using an older dsdt.aml. Files and lspci/lsusb output are linked. What works: - Sleep/Shutdown - Left side and dock USB ports - Webcam - Audio (using VoodooHDA) - Keyboard and touchpad/stick (using modified PS2 kexts) - Wireless hard toggle (turns Bluetooth and WiFi antennae off and on, Airport recovers connection) - Though probably irrelevant, Chameleon 2 RC4 handles GraphicsEnabler just fine (Quadro FX 770M) What's broke: - Restart(?!) - Right side USB ports and Bluetooth (was using DellBluetoothHCI.kext) - PC Card (tested) and ExpressCard (untested, no cards to test with) - SDHC; VoodooSDHC doesn't seem to do anything at all KEXTs in use (in /Extra/Extensions): AHCIPortInjector.kext AppleACPIBatteryManager.kext AppleACPIPS2Nub.kext ApplePS2Controller.kext DellBluetoothHCI.kext HDAEnabler.kext IOACPIFamily.kext IOAudioFamily.kext IONetworkingFamily.kext IOPCCardFamily.kext IOPCIFamily.kext.BACKUP Intel82566MM.kext OSvKernDSPLib.kext OpenHaltRestart.kext PlatformUUID.kext VoodooHDA.kext fakesmc.kext SleepEnabler.kext (in /S/L/E) UNMODIFIED dsdt.dsl: http://pastebin.com/bN5gb1W2 MODIFIED dsdt.dsl using instructions from post 1: http://pastebin.com/GF92UAsF I'm posting from within Mac OS right now, I'll have lspci and lsusb up in a minute.

My previous setup used the unmodified dsdt.dsl listed above, plus a few additional kexts, along with ClamShellDisplay, in 10.6.2. Updating to .3 broke sleep and ClamShell completely, so I tried using these dsdt instructions to make them work. The tradeoff was non-functioning USB ports and Bluetooth, which I can sort of live without (except that I have a Bluetooth mouse). Any help would be appreciated.

CalaverX11 Posted April 22, 2010 Share Posted April 22, 2010 Update, and interesting find: The right-side USB ports and Bluetooth DO work with this dsdt--after booting into Ubuntu, and rebooting into Snow. Another piece to the puzzle. Apparently, the ACPI calls from a cold boot aren't sufficient. Rebooting from Ubuntu into Snow Leopard doesn't fully power off the laptop and doesn't send calls to devices to power down, so devices are active and detectable when OSX loads. But starting from a cold boot, not all of the buses initialize properly. Why is this? Can this be fixed in my dsdt, or do I need to start from scratch? Also: here's a dump from Ubuntu from /proc/acpi/dsdt (decompiled using iasl in Ubuntu): http://pastebin.com/kQc2nau5 Link to comment Share on other sites More sharing options...
Brett Whinnen Posted April 22, 2010 Share Posted April 22, 2010 You did this fix? As this fixed a very similar issue with the M1530 and USB detection. Required for Snow Leopard: Fix USB Devices Randomly Not Working - Added 2009/20/14Reportedly, some are having issues with USB randomly not working on startup, but then trying again will bring the USB back. I haven't actually experienced this. Perhaps it is Snow Leopard specific? Jkbuha and FMulder have come up with this fix (thanks!): EDIT 2009/10/22 -> I've now updated to Snow Leopard, and sure enough this is REQUIRED for proper USB function.

CalaverX11 Posted April 22, 2010 Share Posted April 22, 2010 You did this fix? As this fixed a very similar issue with the M1530 and USB detection. Yes. Now it's working. Here's what happened. Up until today, I was using getDSDT to get a dsdt dump from the machine in its running state in OS X. I was already using a slightly-modified dsdt.aml I got from another user, which apparently was being pulled by getDSDT; I compared it to another modified dsdt.aml I had saved from a backup, and they were identical. So I used the /proc/acpi/dsdt dump I made and started from scratch, with a pure, untouched dsdt template. I added the fixes for: - USB (removing IRQNoFlags mentioned above) - ClamShell - Shutdown and Master Chief's OSXRestart.kext (thank you for that, btw). I skipped the EHC2 and EHCI additions, as well as the DTGP addition. I then compiled using DSDT Patcher -newHPET. After confirming no kernel panics or kext issues using -s -v -x -f, I rebooted and let the OS load on its own. As of now, I have working: - USB (all ports, machine and dock) - Sleep, Shutdown (using patches) - Restart (using OSXRestart.kext) - Bluetooth (using latest DellBluetoothHCI.kext) The toggle switch appears to be working as well. Right now my fan is blowing like mad, but the machine is a little warm and it's not very cool in this room, so I'll have a better idea of the stepping/cooling ability later on tonight. Most importantly, thanks to this guide, I'm several HUGE steps closer to having a Dell Precision M4400 MacBook Pro equivalent. If anybody is interested (particularly the thread OP immo), I can detail everything I used to get vanilla 10.6.3 running on my M4400 in its current state, which includes the dsdt patches I found here, which were the biggest help of all.

Immo I appear to be back at square one...after doing a few more reboots using the tools above, the USB/Bluetooth functionality seems to be totally random and intermittent. I'm going to try a few more DSDT hacks to see if I can make it work. Everything else (sleep, shutdown, restart) works as advertised. This is the ONLY thing preventing me from making it 100% useable. If anybody can offer any insight outside of everything from the first page, I'd appreciate it. Link to comment Share on other sites More sharing options...

CalaverX11 Posted April 26, 2010 Share Posted April 26, 2010 At the end of the day, persistence and tenacity pays off. I combined elements of the tutorial here with this one and this one. USB and Bluetooth still refused to work even with the patched DSDT, but I found another solution in a patched IOPCIFamily.kext. I now have an M4400 with working shutdown, restart, sleep, and fully-functional USB and Bluetooth. My next mission will be to patch SSDT to enable C-states. Since removing NullCPUPowerManagement.kext my machine IS running quite a bit hotter, so if I can get proper power stepping re-enabled that will be one of the last pieces to the puzzle.

Since removing NullCPUPowerManagement.kext my machine IS running quite a bit hotter, so if I can get proper power stepping re-enabled that will be one of the last pieces to the puzzle. Sounds like a good plan. C-States would be great! Link to comment Share on other sites More sharing options...
