OvmfPkg/BaseMemEncryptTdxLib: Handle retry result of MapGPA

2023-11-09T17:15:39+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4572 According to section 3.2 of the [GHCI] document, if the return status of MapGPA is "TDG.VP.VMCALL_RETRY", TD must retry this operation for the pages in the region starting at the GPA specified in R11. In this patch, when a retry state is detected, TDVF needs to retry the mapping with the specified address from the output results of TdVmCall.

OvmfPkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout OvmfPkg. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel Reviewed-by: Sunil V L

OvmfPkg/BaseMemEncryptTdxLib: Refactor error handle of SetOrClearSharedBit

2023-01-18T05:11:07+00:00

The previous implementation of SetOrClearSharedBit doesn't handle the error correctly. In this patch SetOrClearSharedBit is changed to return error code so that the caller can handle it.

OvmfPkg/BaseMemEncryptTdxLib: Add TDX helper library

2022-04-02T08:15:12+00:00

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 Add Intel Tdx helper library. The library provides the routines to: - set or clear Shared bit for a given memory region. - query whether TDX is enabled. Please be noted, there a lot of duplicated codes for Page Table operations. These codes should be moved to a common library (PageTablesLib) so that it is more friendly for review and maintain. There is a new feature requirement https://bugzilla.tianocore.org/show_bug.cgi?id=847 which is to implement the library. After the lib is introduced, BaseMemEncryptTdxLib will be refactored.
