    10.8.5 Kernel [XCPM-free]

    Version

    1,095 downloads

    UPDATE: Thanks to the efforts of RehabMan, Clover/Chameleon both have kernel PM patches built in to deal with the CPU checks in newer revisions. You'd be better off using one of those instead of this kernel now. It has been rendered obsolete by his patches. ORIGINAL CONTENT: compiled this kernel from Apple's source and since they don't include XCPM in their source, this kernel is without it. This kernel is recommended to anyone who experiences instant reboots with the vanilla 10.8.5 kernel. With the exception of lacking XCPM, this kernel is completely unaltered from the vanilla stock version. A patched AppleIntelCPUPowerManagement.kext from 10.8.5 is REQUIRED if you expect CPUPM functionality. Please consider rating this if you found it useful. Thank you and enjoy. Credit to RehabMan for discovering XCPM isn't included in Apple's sources when he compiled his 10.9 kernel. Thanks to ameris_cyning for reminding me to add the patched AICPUPM requirement.
  2. Hello, I've been trying to reach install screen for a few days now and still with 0 success. I create my USB using latest clover (r3949 if not mistaken), choose to install UEFI and then choose osxAptioFixDrv (I've tried both, neither of them worked). So far what I get is XCPM:Registered message and then the computer instantly reboots. Laptop specs: Intel i5-5200U Broadwell 6GB RAM 1 TB hdd Intel 5500 GT940M 2GB Kexts I have while booting Clover: AHCI_Intel_Generic_SATA.kext FakeSMC.kext ApplePS2SmartTouchPad.kext Flags while booting: -v -x -f nv_disabled=1 GraphicsEnabler=No (I've tried various combinations of flags, just verboose, with safe mode, without and so on..) Here is a video with a preview what happens when booting: https://www.youtube.com/watch?v=HvwH2XTn06E
  3. Hi everyone. I managed to install Yosemite with Clover bootloader and the main things work fine. However, there are a few things to fix... First of all i wanted to patch my AMD5000Controller and AMDRadeonX3000 kexts on-the-fly; i just need to add my vga to the info.plist inside those kexts. so i put this inside config.plist: <dict> <key>Name</key> <string>AMD5000Controller</string> <key>InfoPlistPatch</key> <true/> <key>Find</key> <string>68A11002</string> <key>Replace</key> <string>68BE1002</string> </dict> <dict> <key>Name</key> <string>AMDRadeonX3000</string> <key>InfoPlistPatch</key> <true/> <key>Find</key> <string>68A11002</string> <key>Replace</key> <string>68BE1002</string> </dict> buuuuut, it does not work. i tried both with <data> and <string>, nothing. Also it does not even work if i just put the modified kexts inside 10.10 kexts clover's folder. I need to keep the modded kexts in s/l/e... why? Second, wake doesn't work. Sleep works but when i wake up i only get a black screen. Third, i read that since mavericks the kext AppleIntelCPUPowerManagement (and others) is not needed and loaded anymore, cause is all managed by Xnu CPU Power Management. In my case however the kext is loaded, and sysctl machdep.xcpm.mode gives me 0. This seems not causing any problem, but... I don't know. Maybe something's wrong? To solve these i tried to generate and use dsdt and ssdt but didn't make any difference at all, so i erased them. CPU is working perfectly, i think... I have all the p-states. I also tried patching aicpupm kext to solve the sleep problem but it messed me some things so i put back the original one. Could anyone help me in any way? Thanks
  4. Hey guys I know abunch of us have working X99 based Asus installs. Two have given me clover configs that should do full XCPM turbo OC, all usb, and told Apple hda script should identify the codec and patch properly. The only thing that has worked is XCPM, which guy with same OC as my i7 5820k had 4.6ghz turbo OC, with his files I'd get 4.5ghz to show this inconsistency. So what are the latest fixes for our XCPM and X99 usb? Seems most threads relating to our boards are old. I'm sure theres better kexts. I'll be doing some work on mine in goals of near full USB, XCPM, and Audio. I'll post up the fixes I find if I can.

  6. Can anyone confirm what support is like in Sierra for X99 Is power management/speed step working well? Is there a definitive method for getting speed step working? Presently I'm running a stable rig on El Capitan and wondering if it is worth upgrading. Many thanks
  7. Hello all, This question is for the cpu power management folks. In the olden days, there was an -xcpm_ipi kernel flag for multi cpu systems. Since High Sierra deprecated those flags I've been searching for any way to enable xnu power management for Ivy Bridge - EP. Are there known kernel patches to enable this? Is it even possible in a post-sierra world? Appreciate any help.
  8. My CPU is Intel i7-3770 (3.4 ghz) and it can turbo to 3.9 ghz. And my OS version is Sierra 10.12.6 install by clover and #####. At first, my CPU block at 3.4 ghz due to XCPM of ivy bridge is disable in Sierra. Then I open XCPM in Clover Configurator - Kernal and Kext Patches - KernelIvyXCPM I use the and boot clover with argument -xcpm and i7 3770 can turbo to 3.9 ghz successfully. However, there are only 6 channel at all, 1.6, 3.4, 3.6,3.7,3.8,3.9. I'm wondering is this correct or there should be any method open the channel between 1.6 and 3.4 Thanks!
  9. Overview The first version of OS X to support Haswell CPUs was Mountain Lion 10.8.5. At the same time, for certain CPUs including Haswell, Apple moved CPU power management from AppleIntelCPUPowerManagement.kext to the kernel. This technology is known as XCPM (Xnu CPU Power Management). This technology is enabled for Haswell CPUs automatically and can optionally be use with Ivy Bridge CPUs with the -xcpm kernel flag. The problem is Apple's computers do not have a locked MSR 0xE2, yet most PC laptops do. When the kernel tries to write to this locked register, it causes a panic. And this panic happens so early in the process that it results in a reboot. Similar to how we must patch AppleIntelCPUPowerManagement.kext for locked CPU MSR 0xE2, the kernel must also be patched for CPUs using XCPM to avoid this reboot. Background information can be found here: http://www.insanelymac.com/forum/topic/293503-haswell-early-reboot-mavericks-locked-msrs-and-hp-envy-15-j063cl-i7-4700mq How to patch the kernel After creating your USB installer, you should have the "vanilla" kernel. Here's how to patch it: For Yosemite 10.10.x: # in Terminal, assuming your USB is called Installer cp /Volumes/Installer/System/Library/Kernels/kernel ~/Desktop/kernel_backup cp /Volumes/Installer/System/Library/Kernels/kernel ~/Desktop/kernel cd ~/Desktop # now patch the kernel at ~/Desktop/kernel perl -pi -e 's|\xe2\x00\x00\x00\x02\x00\x00\x00|\x00\x00\x00\x00\x00\x00\x00\x00|g' kernel perl -pi -e 's|\xe2\x00\x00\x00\x4c\x00\x00\x00|\x00\x00\x00\x00\x00\x00\x00\x00|g' kernel perl -pi -e 's|\xe2\x00\x00\x00\x90\x01\x00\x00|\x00\x00\x00\x00\x00\x00\x00\x00|g' kernel # patched kernel is now at ~/Desktop/kernel sudo cp kernel /Volumes/Installer/System/Library/Kernels/kernel After you install OS X to your HDD, you will have vanilla kernel on the HDD, leading to the same instant reboot problem. So, you must re-enter the OS X installer, and go into Terminal (using Utilities -> Terminal) and replace the kernel with the patched version: # in Terminal from the OS X installer, assuming your HDD volume is called "Macintosh HD" cp /System/Library/Kernels/kernel "/Volumes/Macintosh HD/System/Library/Kernels/kernel" After that, you can exit the installer, and boot into the installed partition to finish installation and reach the desktop. MD5 sums for the kernel Check your md5 sums with: md5 /Volumes/Installer/System/Library/Kernels/kernel 10.10/10.10.1 kernelvanilla: 9f1768fddec369e545d938f0f4f76350 xcpm patched: 1938ebb0bd6cdc00930543025d3df887 10.10.2 kernel vanilla: 8a985412c42c153601580fd1b8bc360e xcpm patched: cc46457172315aea68d8e1f957d2746c 10.10.3 kernel vanilla: fd9b0ed2a37a393d145033a2f0ce46b4 xcpm patched: d89759c11c5f434b4434b6fbf0464d6c A note about Clover The Clover bootloader has this patch built-in with the config.plist/KernelAndKextPatches/KernelPm option. Keep in mind if you're not using Clover (and KernelPm), you will have to re-patch the (new) kernel after any OS X update. With Clover, it is automatic provided the code in Clover is updated (if necessary) to patch the (new) kernel.
