Using static patching, we apply "Rename IGPU to GFX0" in order to rename this object.

In OS X, power management for Intel graphics is not enabled unless this device is named IGPU. For example, most PC laptops use GFX0 for the integrated Intel GPU object (Intel HD Graphics).
#Hex fiend windows 8 Patch#
Since OS X can depend on specific ACPI object names used by Macs, a common patch is to rename an object in the native ACPI set. For example, you might use binary patching to disable or rename components in the native ACPI set, and then replace it with additional SSDTs. In some cases, more than one mechanism must be used to accomplish a single goal. A perfect example you're already familiar with is the SSDT.aml that is generated by Pike's ssdtPRgen.sh. Since many OS X patches involve adding properties to ioreg with a _DSM method, it is often adequate to simply add an SSDT which contains the additional _DSM method instead of patching the native ACPI files.

By placing additional SSDTs into ACPI/patched, we can essentially add code to this ACPI set. It is fully documented in the ACPI spec.ĪCPI namespace is built by merging the DSDT and SSDTs at load time. You need to have an understanding of the binary AML format. Clover loads the native ACPI files, applies the patches specified in ACPI/Patches using binary search/replace, then injects the patched ACPI. DSDT "Fixes" are useful for implementing patches that are difficult or impossible to implement with ACPI/DSDT/Patches or additional SSDTs.ĭSDT/Patches allows for binary search and replace by Clover. Most of the time, there are not many DSDT "Fixes" needed for basic functionality. You can read the Clover wiki for more information on each patch. As an other example, "Fix _WAK Arg0 v2" can be accomplished with "FixWAK". For example, "IRQ Fix" can be accomplished with "FixHPET" "FixIPIC" "FixRTC" and "FixTMR". Each "Fix" can do a particular kind of patching that can be used instead of typical patching you might do with MaciASL and static patching. Don't expect step-by-step and spoon feeding in this thread.Ĭlover provides a few methods for accomplishing ACPI hotpatch:ĭSDT/Fixes provide fixed function ACPI patching. You should also have an understanding of the ACPI spec, binary patching, programming, and ACPI concepts. You should have a solid understanding of static ACPI patching before attempting to hotpatch. With the techniques detailed in this guide, the changes can be made directly to the ACPI binaries provided by BIOS, skipping the extract, disassembly, and recompilation steps. In order to inject patched ACPI files, we extract native ACPI, disassemble them, make changes, then recompile and place the files in ACPI/patched, so that Clover injects the patched ACPI instead of native ACPI. That guide uses what is known as "static patching".
