MdeModulePkg: Add CxlIo.h protocol

2026-05-01T06:48:04+00:00

Create a CXL protocol for interacting with CXL endpoint devices. CXL devices are necessarily also PCI devices, so the PCI IO protocol is also provided as part of the CXL protocol. The protocol provides access to the following operations for CXL devices: - Read from a DVSEC register block - Write to a DVSEC register block - Perform DOE transaction This set of operation is sufficient to implement BIOS-level CXL functionality.

MdeModulePkg: Replace include guards with #pragma once

2026-02-23T21:01:28+00:00

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

MdeModulePkg/VariablePolicy: Add more granular variable policy querying

2023-10-31T14:40:50+00:00

Introduces two new APIs to EDKII_VARIABLE_POLICY_PROTOCOL: 1. GetVariablePolicyInfo() 2. GetLockOnVariableStateVariablePolicyInfo() These allow a caller to retrieve policy information associated with a UEFI variable given the variable name and vendor GUID. GetVariablePolicyInfo() - Returns the variable policy applied to the UEFI variable. If the variable policy is applied toward an individual UEFI variable, that name can optionally be returned. GetLockOnVariableStateVariablePolicyInfo() - Returns the Lock on Variable State policy applied to the UEFI variable. If the Lock on Variable State policy is applied to a specific variable name, that name can optionally be returned. These functions can be useful for a variety of purposes such as auditing, testing, and functional flows. Also fixed some variable name typos in code touched by the changes.

MdeModulePkg: UsbNetwork: fix Ethernet functional descriptor processing

2023-10-16T22:49:33+00:00

This patch fixes wrong condition because of UINT16 value to integer promotion. NumberMcFilters is UINT16 value, so when bitwise shift operator applied to small integer type, the operation is preceded by integral promotion. This is described in MISRA-C:2004 guideline as Rule 10.5: "If the bitwise operators ~ and << are applied to an operand of underlying type unsigned char or unsigned short, the result shall be immediately cast to the underlying type of the operand." A simple fix for this issue would be the following: if ((UINT16)(UsbEthFunDescriptor.NumberMcFilters << 1) == 0) But this patch proposes to use bitwise AND operation with a proper bit mask rather than shifting to prevent similar mistakes in future.
