Augustin Cavalier 3d196bd28c kernel/x86_64: Handle LA57 paging in VMTranslationMap page table walks.
Without this, we will fail to free the last level of page tables.
This bug has apparently been present since LA57 was originally
introduced years ago, however it was likely not a problem before
now because only the BIOS bootloader has support for it, while
systems that support LA57 are more likely to be booted via EFI.

While at it, fix the address mask for non-LA57 in
DebugGetReverseMappingInfo.

Should fix #19460.

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
