Firmware Changelogs

Firmware/System Interface Updates

More comprehensive platform support: Covers core platforms such as 3A/B/C/D/E6000 and LS2K3000
Improved stability: Improved controller-related issues related to boot, HDMI display, PCIe compatibility, and IOMMU
Enhanced functionality: Continued refinement of capabilities and information related to SE, IPv6 PXE, and ACPI/SMBIOS
Better maintainability: Ongoing optimization of builds, CI, coding standards, and toolchains

RefCode
- Added support for slimmed-down core versions of the 3B6000M series and others
- Ongoing iterative upgrades to PHY, MRC, SMC, and IPMI

General features:

Enhanced support for the 6000 series platform to enable ACPI.EDAC reporting of ECC status to the kernel
Continued optimization of the emulator’s MultiArch support for third-party x86 peripheral cards. The simulation option can be temporarily disabled via the interface if certain high-end network cards experience 概率性重启模拟异常
Added and enhanced SE capabilities, including support for DeviceMode and the new SE RNG API
Enhanced parsing support for older EDID versions
Added paging support for the gopinfo subcommand
Strengthened driver restrictions on FrameBuffer address modifications
Added IPv6 PXE-related drivers
Improved EC management read/write interfaces
Added SMBIOS API for updating peripheral identifiers
Added BGRT support to meet community needs and pass GOP information across all platforms
Added CPU ThermalZone _STR descriptions to support 3C/D/E6000 platforms
Updated GPIO resources to comply with the V3.2 specification
Added DRAM MemoryTechnology identification to Smbios.Type17 to meet community needs
Upgraded LsIpmiPkg from 1.3.11 to 1.3.13
- Removed the configurable LegacyMode boot interface from BMC
- Added support for configuring IPv6 and dynamically enabling DHCP
- Adjusted LAN to support OCP shared port switching
- Switched to a new BMC synchronization policy; depended on BMC.v2.3.0

General Optimizations:

Optimized the BootOption boot entry loading strategy
Optimized the availability of the ShellLib/SmbiosUpdate and ShellLib/Spi subcommands and related fixes to meet community needs
Synchronized with upstream to enhance security mechanisms and optimize cleanup of keyboard queue residues after password reading
Synchronized with upstream to support modifications to the SMBIOS.Type4.Cache data structure
Optimized read/write strategy for GmacPhy EEPROM
Upgraded MRC memory to optimize and improve Spec2017 floating-point performance
Enhanced help information for interface display options
Synchronized with upstream to optimize OptionRom search strategy
Adjusted MPS scanning strategy for AI+SW multi-hybrid device topologies
Cleaned up and optimized certain code structures and compiler compatibility warnings

General Issue Fixes:

Fixed PCR0 secure boot measurement variation issues
Fixed Console display experience issues in high-resolution scenarios
Fixed incorrect IOMMU.IVRS SegNum and GROUP information on 3C6000 dual-channel and 3B6000 platforms
Corrected an issue where the Setup interface on the 3B6000 platform incorrectly displayed 4 memory channels when the actual count was 2
Fixed an issue causing exceptions on the 2K3000 platform after disabling DVFS
Fixed an issue where downstream bus numbers might not be properly cleared when switching display policies
Fixed a warning in newer versions of IASL
Fixed the PPTT Package Number error
Adjusted the number of EIO/BIO tables on platforms with 8 or more nodes to avoid conflicts with perf interrupts
Fixed a series of stability and graphics (HDMI/DP) display issues on the 2K3000 platform
