| - | ===== Problem ===== | ||
| - | 這是跑HLK HyperVisor Code Integrity Readiness Test中的錯誤。問題是Windows在Win8後基於安全性考量，建議將NonPagedPool改為使用NonPagedPoolNx。本篇文章主要分享我的改法。\\ | ||

| - | ===== How to resolve? ===== | ||
| - | 由於我的情況不需要使用到Executable nonpaged pool，因此只需要將NonPagedPool改為NonPagedPoolNx即可。在我們的情況，有以下幾點要考慮: | ||
| - | - WDK是6000，因此某些Macro要自己宣告。 | ||
| - | - NonPagedPoolNx為win8以後才支援，但我們又要共用同一隻driver，因此code要針對版本做處理。 | ||
| - | <code cpp> | ||
| - | #define NonPagedPoolNx 512 | ||
| - | #define NTDDI_WIN8 0x06020000 | ||
| - | int getNonPagePoolNx(){ | ||
| - | // Win8 later | ||
| - | if( RtlIsNtDdiVersionAvailable(NTDDI_WIN8) ) { | ||
| - | return NonPagedPoolNx; | ||
| - | } | ||
| - | return NonPagedPool; | ||
| - | } | ||
| - | </code> | ||
| - | 假如系統版本大於等於Win8，我就會使用NonPagedPoolNx；反之則使用NonPagedPool。Client code如下: | ||
| - | <code cpp> | ||
| - | pci_bus_interface=(PCI_BUS_INTERFACE)ExAllocatePool(getNonPagePoolNx(), | ||
| - | sizeof(PCI_BUS_INTERFACE)); | ||
| - | </code> | ||
