| | | | | | | | | | | | | | In preparation of providing a standalone MM based FTW driver, move the existing SMM driver to the new MM services table, and factor out some pieces that are specific to the traditional driver, mainly related to the use of UEFI boot services, which are not accessible to standalone MM drivers.

* MdeModulePkg: Refine casting expression result to bigger sizeHao Wu2017-03-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

* MdeModulePkg: FaultTolerantWriteDxe: mellow DEBUGs about workspace reinitLaszlo Ersek2015-10-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IsValidWorkSpace() function checks if the working block header of the workspace is valid. A mismatch detected by this function is not necessarily an error; it can happen with an as-yet unwritten flash chip, which is e.g. common and normal when a new ArmVirtQemu virtual machine is booted. Therefore downgrade the message emitted by IsValidWorkSpace() from EFI_D_ERROR to EFI_D_INFO, and change the wording from "error" to "mismatch". The only caller of IsValidWorkSpace(), InitFtwProtocol(), handles all of the following cases: (1) IsValidWorkSpace() succeeds for the working block -- this is normal operation, (2) IsValidWorkSpace() fails for the working block, but succeeds for the spare block -- InitFtwProtocol() then restores the working block from the spare block, (3) IsValidWorkSpace() fails for both the working and spare blocks -- InitFtwProtocol() reinitializes the full workspace. In cases (2) and (3), InitFtwProtocol() logs additional messages about the branch taken. Their current level is EFI_D_ERROR, but the messages are arguably informative, not necessarily error reports. Downgrade these messages from EFI_D_ERROR to EFI_D_INFO, so that they don't clutter the debug output when the PcdDebugPrintErrorLevel mask only enables EFI_D_ERROR (i.e., in a "silent" build). These messages have annoyed / confused users; see for example: - https://bugzilla.redhat.com/show_bug.cgi?id=1270279 Cc: Star Zeng <star.zeng@intel.com> Cc: Liming Gao <liming.gao@intel.com> Cc: Drew Jones <drjones@redhat.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Star Zeng <star.zeng@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@18619 6f19259b-4bc3-4df7-8a09-765794883524

* MdeModulePkg: Variable drivers robustly handle crashes during Reclaim().Star Zeng2013-07-031-6/+6
| | | | | | | | | | | PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid. Solution: Add a FaultTolerantWritePei driver to check and provide the FTW last write status, then PEI variable and early phase(before FTW protocol ready) of DXE variable can check the status and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.
