* Work-in-progress support for non-accelerated X11 on *some* sti(4) frame buffers;miod2015-04-051-2/+17
| | | | | | | | | based upon the old HP ngle X11 driver. Currently limited to CRX (720/735/750), Timber (710, old 715), Artist (712, 715) and EG (B-series), however the colormap isn't set up correctly on Timber and EG yet. Joint work with Artem Falcon, now in good enough shape to be worked further in the tree.
* Split sti structures into rom-related information and screen-relatedmiod2009-02-061-64/+82
| | | | | | | | | | | information. This is preliminary work to help eventually supporting the dual-head ELK model. Also split the initialization code in several routines, this makes the code easier to read, and makes it easier to release resources upon failure. Finally, don't forget to clear the text planes on non-console displays when initializing.

| | | | | | | | access to the sti rom, as this seems to be necessary for sti@pci; hide this with macros so that platforms which do not have pci support (i.e. hp300) do not get bloated from this. ok mickey@

* Change sti attachment to pass an array of base addresses for the sti regions,miod2006-12-181-4/+5
| | | | | | | | instead of using the rom mapping for region #0 and the device mapping for region #1. This will allow sti devices on which regions may be relative to different origins to attach (to be used very soon). ok mickey@

* Split sti softc in two structures, one device-related for regular devicemiod2005-02-271-27/+45
| | | | | | | | | | | attachment and interface, one screen-attached for the real work. The attachment code is now required to decide whether sti_end_attach() is run immediately, or as a startuphook. This allows hp300 to initialize sti early, and use it as a console; hppa is functionally unchanged, as it uses the PROM console until the root device is mounted.
* Two sti(4) changes necessary for hp300:miod2005-01-231-2/+2
| | | | | | | | - specify which microcode bank (pa or m68k) to use at attachment time. - compensate for broken 8.02 m68k code which reports wrong frame buffer offset. ok mickey@

attach point for wsdisplay. a few problems may exist w/ certain prom versions. tested in byte- and word-wide modes. no support yet for multiple resolutions and fonts. pci not tested (obviously).
