on sparc64 with a Sun PGX32 / TechSource Raptor GFX 8P
So far it accelerates block copies, rectangle fills and the cursor, it
supports the usual wsdisplay / vcons stuff.
TODO:
- character drawing by hardware so we don't need to map the framebuffer
- DDC2 support
- mode setting
This driver still relies on the firmware to set up graphics modes etc. so it
won't work on x86 ( or non-OpenFirmware for that matter ) unless you use the
VESA BIOS to set up graphics and pass the right properties ( width, height
etc. ) to the driver. For the same reason it will work only if it's the
OpenFirmware console.
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.
Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).
Discussed on <tech-kern>, reviewed by <ad>.

Stops errors such as the following when probing SATA drives through
controllers that offer the legacy pciide interface:

its derivatives, and I haven't the time myself. In struct
pciide_product_desc, provide a tiny bit of commented-out code to
guide an enterprising developer who takes on the immense task.
- Remove redundant assertions.
- Properly check for NULL pointers.
- No real need to keep track whether the internal event handler is installed.
- Add a missing function to pass possible extra information associated with
an event. Mentioned in the specification.
Import acpiwmi(4) from Jukka Ruohonen. From the PR:
Attached is a driver that implements ACPI WMI API:
http://www.microsoft.com/whdc/system/pnppwr/wmi/wmi-acpi.mspx
The WMI is used to provide a generic interface for OEMs to use certain
platform/laptop-specific additions to the standard ACPI in a somewhat
portable way. These can be hotkeys for additional buttons, different event
handlers (wireless kill switch, lid switch, etc.), and so on. At least HP
and Acer use it by default nowadays.
The benefit of this interface would be portability. For an example, instead
of hpqlb(4) that works only with certain HP models, we could have a generic
HP WMI-driver that should work in theory across all HP laptops. On many new
laptops WMI may also be the only way to access laptop/manufacturer-specific
features.
