- program aperture endianness to match host, now xf86-video-wsfb works as
expected
- properly restore the colour map when er-entering terminal emulation
While there, don't pretend to support the Permedia2 non-V - I don't have the
hardware and it has never been tested in the first place. The only hardware
this has been tested on is a TechSource Raptor GFX 8P / Sun PGX32 which
happens to be a Permedia2V with Sun firmware.
while there, fix pm2fb_bitblt() packed mode, for real this time
TODO:
- use packed mode when uploading glyphs
- let the hardware do the alpha blending if possible
- mode setting
- DDC2 support, so far only used for WSDISPLAYIO_GET_EDID
- fix 8 bit support, use packed mode for some extra speed
- pm2 and pm2v have different DACs, deal with it where appropriate
where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.
It returns the bus id and allows userland (like Xorg) to create mapping
of ttyE? and bus id. For now only PCI is implemented.
First discussed with macallan@ then public on tech-kern@ and tech-x11@
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.
