21 hoursMdeModulePkg/EmmcBlockIoPei: Use UINTN for ADMA descriptor table indexingMichael D Kinney2-4/+5
In BuildAdmaDescTable(), Index and Entries were UINT64. Using a 64-bit Index for array subscripting `Trb->AdmaDesc[Index]` generates 64-bit multiplication on 32-bit architectures (IA32). Change Index and Entries to UINTN so array indexing uses native integer math, and add BaseLib to the module INF. Signed-off-by: Michael D Kinney <michael.d.kinney@intel.com>
2026-08-05MdeModulePkg: Fix comparison with wider widthsAaron Pop1-1/+1
https://codeql.github.com/codeql-query-help/cpp/cpp-comparison-with-wider-type If the narrow type (smaller range) is compared against a wide type (larger range), the narrow value may overflow before reaching the wide value. This can cause unexpected behavior, such as: Infinite loops (loop condition never becomes false). Incorrect logic (comparison results are misleading).

2026-06-24MdeModulePkg: SdBlockIoPei: Fix uninitialized variable warningsTuan Phan1-3/+21
In SdPeimIdentification(), the compiler may inline SdPeimHcRwMmio() because it only performs simple MMIO reads and writes. When inlined, the fourth argument can appear to follow multiple control-flow paths (MMIO read versus MMIO write), which may cause the compiler to report a potential uninitialized variable warning when the value is used later if it was not initialized up front. Add an explicit Status check, consistent with other code in this file, to make the control flow explicit and eliminate the compiler warning. Signed-off-by: Tuan Phan <tuan.phan@oss.qualcomm.com>
2026-02-24MdeModulePkg: Replace include guards with #pragma onceMichael Kubacki12-48/+12
Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki <michael.kubacki@microsoft.com>

2017-08-14MdeModulePkg/EmmcDxe: Make sure no extra data is erased by EraseBlocksHao Wu1-4/+152
V3 changes: Add debug messages for new return path when successfully erase the specified blocks. Refine logic for calculating the size for writing zeros to device. V2 changes: The Trim command is not supported on all eMMC devices. For those devices that do not support such command, add codes to handle the scenario. Commit message: The current implementation of the Erase Block Protocol service EraseBlocks() uses the erase command. According to spec eMMC Electrical Standard 5.1, Section 6.6.9: The erasable unit of the eMMC is the "Erase Group"; Erase group is measured in write blocks that are the basic writable units of the Device. ... When the Erase is executed it will apply to all write blocks within an erase group. However, code logic in function EmmcEraseBlocks() does not check whether the blocks to be erased form complete erase groups. Missing such checks will lead to erasing extra data on the device. This commit will: a. If the device support the Trim command, use the Trim command to perform the erase operations for eMMC devices. According to the spec: Unlike the Erase command, the Trim function applies the erase operation to write blocks instead of erase groups. b. If the device does not support the Trim command, use the Erase command to erase the data in the erase groups. And write zeros to those blocks that cannot form a complete erase group.
