* 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
* 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

* EfiDSEFix: improve g_CiOptions address validationv1.2.1Matthijs Lavrijsen2021-05-25
| | | | | | | | - Verify expected lengths of instructions - Verify CipInitialize is in PAGE - Verify g_CiOptions is in either .data or CiPolicy Fixes #31 (regression due to KB5003173 fix)
* 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

* Loader: call BmSetMemoryTypeInformationVariablev1.1Mattiwatti2020-05-28
| | | | | | Note that BmSetMemoryTypeInformationVariable() is told by the loader that the image being loaded is *not* a boot application, which is a blatant lie. The reason for doing this is to prevent BmSetMemoryTypeInformationVariable() from performing a warm reset of the system due to a change in the memory type info. (Again, and again, and again...) This is an attempt to fix S4 (hibernate) entry/resume issues; see #12.

* Fix potential recursive self-boot by Loader.efiMattiwatti2019-07-09
| | | | | | The EFI variable "BootCurrent" corresponds to XXXX in some variable "BootXXXX", and this value was being used to guard against recursive self-booting. However, EfiBootManagerGetLoadOptions() already returns the options sorted by the contents of the "BootOrder" variable, which means that XXXX does not necessarily correspond to the linear index in a for loop. Instead use BootOptions[Index].OptionNumber to retrieve and compare the original value of XXXX Fixes #5
* EfiDSEFix: HDE64 fixesMattiwatti2019-05-30
| | | | | | - Make hde64_table const to prevent it from ending up in .data - #include <intrin.h> because Clang gets confused by __stosb without it - Fix various warnings
