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 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 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
