Augustin Cavalier 6c675bab59 XHCI: Defer writing the cycle bits for the "wrapping" link TRB.
There is already a comment above this that some controllers choke if the
target of a link TRB is invalid, and thus to not write the cycle bit
of the link TRB until said target is valid, but we did not follow that
when writing the link TRB to go back to the beginning of the ring.

Also put in a memory_write_barrier before writing the cycle bits,
just to be sure.

Tested in QEMU. May help with errors seen in #17749.

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!
