Roadmap

Version 0.1 (previous)

Initial release

Version 0.2 (actual)

  • Blastproof:
    • New boot password screen, with power options
    • Support for custom keyboard layouts using correspondance tables
    • Config is now stored in .cfg files
    • VFTM support
    • Partition tables is now parsed without relying on UEFI firmware
    • New configuration key: kernel_kbd_events_queue_capacity
  • Vyx:
    • Support for payloads with custom mappings options
  • Initfsgen:
    • The initfs-footprint.bin file is now named initfsfp.bin
    • The signsyst-hash.bin file is now named sshash.bin
  • Keygen:
    • Removed layout conversion feature
    • The utility will now check if a password is provided in the VYSTEM_KEYGEN_PASSWORD environnement variable
    • The manual password setup will still be proposed if VYSTEM_KEYGEN_PASSWORD isn't defined or is empty
    • This method of inputing password via VYSTEM_KEYGEN_PASSWORD should ONLY be used in a developpement environnement
    • Keygen now generate root and manifest keypairs, and expect a vftm.sock UNIX socket to transmit manifest keypair to a compatible build system
  • VyBuild:
    • A new build system, see documentation for more informations
  • Commoncrypto:
    • A new library made of three cryptographic libraries, required for Keygen, Initfsgen and VyBuild
  • Vystem B FAT Trusted Manifest:
    • A new signed manifest, injected inside the reserved sectors of the ESP partition FAT32
    • It's signed using a combinaison of Keygen and VyBuild
    • It allow to verify the link between ESP partition and current disk, as well as FAT32 integrity and self bootloader verification
  • Common Lib:
    • In the common folder, new headers that will be accessible to all components of Vystem B will be put here
    • For the moment, it only includes the reference version of each component
  • Shelter:
    • Can now manage TSS, GDT and IDT
    • Can now parse root ACPI table and MADT
    • Can now interact with LAPIC, estimating CPU and LAPIC frequency
    • Can now start APs
    • Can now manages IOAPIC devices and GSI lines as well as legacy IRQs
    • Added thread safety to print, timers and malloc. Added iprint/iprintf/sprintf.
    • Added Device System, endpoints from APIC, TSC, kernel configuration, memory and SMP subsystem are available
    • Device System is not available for the input subsystem yet, as it would requires Ring 3 architecture, that isn't ready for now
    • Add very basic framebuffer support for early kernel progress bar
  • Image build processus:
    • The signatures are now stored as <filename without original extension>.sig files
    • The signatures are now stored inside EFI/BPSIGN folder
    • The bootloader files are now stored inside EFI/BPFILES folder

Version 0.3 (future release with planned additions)

  • Updated SH_STATUS struct
  • New Modular Daemon Unit with the first type being implemented: kernel library. Run in ring 3 with very basic API
  • First features of the VFS, with InitFS drivers
  • MCFG ACPI table parsing, PCIe devices enumeration, first MSI/MSI-X implementation
  • SATA driver, volumes enumeration with integration to the VFS
  • Upgrade to the Device System, with new APIs for the input subsystem and VFS, as well as Device System querying through the VFS
