Oscar Lesta cccb5efb11 acpi_{ac,lid,thermal}: avoid SMAP related KDLs.
While these three worked just fine on my old Atom N450 based netbook,
all caused:

"PANIC: SMAP violation user-mapped address [...] touched from kernel [...]"

on a newer netbook with a Celeron N4020 CPU, before this change.

Side note / drivers status:

- acpi_ac works pretty decently on both machines.
- acpi_lid wrongly returns 0 until you close the lid for the first time.
  Reports correct values after that, but seems to cause power_daemon's
  event loop thread to peg one core to 100%.
- acpi_thermal readings are a mixed bag. Critical temp values Seem OK on
  both machines. Current value generally OK on the older machine, very wrong
  on the newer (reports 429496728.6 C).

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!
