| | | | Fixes #97
* Fix build with current EDK2 masterMatthijs Lavrijsen2023-06-22

|
* Loader: check entry descriptions to determine whether they are WindowsMatthijs Lavrijsen2023-03-26
|
* Loader: remove BdsLibConnectAllDriversToAllControllersMatthijs Lavrijsen2023-03-26
| | | | EfiBootManagerConnectAll provides this functionality now.
* Loader: minor SetHighestAvailableMode improvementsMatthijs Lavrijsen2023-03-26
| | | | | - Add primitive aspect ratio weighting when determining which text mode is best - Move all uses of gST->ConOut to SetHighestAvailableTextMode and exit early if it is NULL
* Loader: handle EFI_SECURITY_VIOLATION from LoadImageMatthijs Lavrijsen2023-03-26
| | | | This behaviour matches that of edk2's UefiBootManagerLib since edk2 commit f7fdd620e8
* EfiGuardDxe: clear and restore CR0.WP when copyingMatthijs Lavrijsen2023-03-26
| | | | This is intended to deal with the UEFI memory protection protocol (EFI_MEMORY_ATTRIBUTE_PROTOCOL) introduced in the UEFI 2.10 specification.
* Add CopyWpMem and SetWpMem routinesMatthijs Lavrijsen2023-03-26
| | | | Additionally make SetServicePointer also clear and restore CR0.WP if needed

* EfiDSEFix -c: error message wordingMatthijs Lavrijsen2023-03-17
| | | | Reference: #60
* EfiGuardDxe: disable VBS for the current bootMatthijs Lavrijsen2023-03-16
| | | | | | | This prevents a bugcheck on Windows 10 and later when VBS is enabled, which was made the default setting in Windows 11. Additionally, EfiDSEFix will not proceed if it detects that VBS is still unexpectedly running (meaning either EfiGuardDxe was never loaded, or it failed to disable VBS). Fixes #59

* Update ntdll.hMatthijs Lavrijsen2023-02-27
|
* Restructure LibraryClasses in .dscMatthijs Lavrijsen2023-02-27
| | | | | | | - Use DxeReportStatusCodeLib as ReportStatusCodeLib implementation instead of RuntimeDxeReportStatusCodeLib, as the latter is not usable by UEFI applications - Move PcdLib, MemoryAllocationLib and ReportStatusCodeLib to the common section used by both EfiGuardDxe and the loader - Remove comments re: EDK2 breaking backward compatibility by introducing RegisterFilterLib and VariablePolicyHelperLib, as edk2-stable202202 is now a year old - Only use BaseMemoryLibOptDxe instead of the default BaseMemoryLib when targeting x86 architectures

* EfiDSEFix: fix BSOD on Windows 10 with KB5003173 when using '-d'Matthijs Lavrijsen2021-05-12
| | | | | | EfiDSEFix was not finding the address of CI!g_CiOptions correctly after KB5003173 changed the layout of CI!CiInitialize. Fixes #28
