dakanji/RefindPlus v0.13.2.AN

on GitHub

Change 01: 23 Feb 22¹.

• Multiple Misc Stability Fixes
  • Major refactoring and restructuring for improved stability
  • Also applied to filesystem drivers
• Adds SupplyUEFI Feature
  • Adds an implementation of the CreateEventEx feature to EFI 1.x units
  • Additionally, the EFI Revision is modified to present as UEFI 2.3
  • This allows the use of UEFI 2.x tools and drivers on Legacy EFI 1.x units in many cases
  • This is particularly the case on Legacy Macs, which already have amended EFI 1.x implementations
  • This functionality can be disabled by setting the decline_uefiemulate token
  • As an aside, the RuntimeServices table is now also amended in AmendSysTable
• Adds SilentBoot Feature
  • RefindPlus inherited a mode where a default selection was run after an instant timeout
  • A shortcut key for a loader could also be pressed to run that particular loader instead
  • This mode is activated by setting the timeout config token to -1
  • However, the RefindPlus screen was briefly loaded before the target option was run
    • This created an unwanted screen flash and also removed the BGRT logo
  • The default selection is now run without showing the screen at all instead (Based on an upstream update)
  • The mode is now truly silent as there is no video output unless overridden (BGRT logos are maintained)
    • Override is initiated by holding down the ESC key immediately after starting RefindPlus
    • Shortcut keys can also be pressed
      • In such cases, the loader associated with the key will be run instead of the default
      • There will be no video output by RefindPlus similar to the default case
• Fixes Forced TextRenderer
  • The TextRenderer feature is forced on in certain circumstances to enable text mode support
  • This appears to have resulted in conflicts on some Macs following a firmware update
  • The firmware update appears to have made changes to screen mode settings
  • The forced activation has been amended to avoid this issue
• Fixes SystemTable Restoration
  • The code was previously not operational
  • This has now been fixed but is now limited to when SupplyUEFI is inactive
• Fixes Major Memory Conflict
  • An item had been wrongly freed and resulted in random crashes when running loaders
  • This bug was introduced in v0.13.2.AC (Commit 6ed58c5)
• Fixes DontScanVolumes for Synced APFS Instances
  • Limited to Single Instance APFS Containers
• Fixes Reported LodePNG Name Collisions
  • This apparently affected Docker builds on Linux
• Amends Handling of Inconsistent EFI Versions
  • RefindPlus now disables all functionality involving UEFI element changes when this is detected
  • A detection of inconsistent EFI versions suggests RefindPlus has been chain-loaded
  • This is most likely to be as a result of chain-loading from OpenCore with ForgeUefiSupport set
  • The disabled features can typically also be set in OpenCore
• Improves ProtectNVRAM Implementation
  • RefindPlus classifies UEFI Loaders into one of the following categories:
    • Opencore, Clover, Linux, MacOS, Windows and Others
  • Only security certificates generated by Windows UEFI Loaders were blocked by ProtectNVRAM
  • However, UEFI Windows installers/updaters may fall into the Others category and generate such certificates
  • Hence, certificates generated by UEFI Loaders that fall into the Others category are now also blocked
  • The feature remains only active on Apple firmware and can be disabled by setting the decline_nvramprotect token
• Improves SyncAPFS Implementation
  • The presence of valid VolUUID and PartGUID is now taken into account
  • SyncAPFS is disabled if either has a NULL Guid value
• Improves Screenshot Feature
  • Feedback on success/failure is given via on-screen messages
  • Each press of the F10 key now results in only one image being saved
    • This is subject to the key press not continuing beyond the on-screen message display
• Improves Memory Management
  • Multiple memory management improvements
• Improves Build Process
  • RELEASE builds are further optimised
    • The MDEPKG_NDEBUG EDK2 functionality is leveraged to:
      • Reduce file size
      • Ensure consistent files on different builds
        • EDK2 otherwise only guarantees functional consistency
        • This now enforces additional structural consistency
        • Builds with different file paths will now be the same
  • Calls to ASSERT, and similar, are activated on DEBUG Builds
    • Failed ASSERT calls put RefindPlus into a Deadloop
  • Enables NOOPT Build Target
    • This is a debug build with misc compile time optimisation items disabled
    • Log Level 2 is only exposed on this build target
  • The REFIT_DEBUG define has been converted to a compiler option
    • The constant is no longer defined in global.h and instead set in RefindPlus.inf
    • This change removes the need for compile time edits to set build targets
    • The requirements are now managed transparently by the build process itself
  • The various *.inf files for filesystem drivers etc, have been standardised
    • These now follow a clearer standard format
• Renames the ignore_previous_boot config option as transient_boot
  • This more accurately describes the feature.
    • The current boot selection is not saved, it becomes transient, but any previously saved boot is set as the default
