Raw Normal View History

Implement support to dynamically change wscons console and kernel colors. Two new ioctls are added to the wsdisplay device, named WSDISPLAY_GMSGATTRS and WSDISPLAY_SMSGATTRS, used to retrieve the actual values and set them, respectively (the name, if you are wondering, comes from "message attributes"). A new emulop is added to the underlying display driver (only vga, for now) which sets the new attribute for the whole screen, without having to clear it. This is optional, which means that this also works with other drivers that don't have this new operation. Five new kernel options have been added, although only documented in i386 kernels (for now): - WSDISPLAY_CUSTOM_OUTPUT, which enables the ioctls described above to change the colors dynamically from userland. This is enabled by default in the GENERIC kernel (as well as others) but disabled on all INSTALL* kernels (as this feature is useless there). - WS_DEFAULT_COLATTR, WS_DEFAULT_MONOATTR, WS_DEFAULT_BG and WS_DEFAULT_FG, which specify the default colors for the console at boot time. These have the same meaning as the (already existing) WS_KERNEL_* variables. wsconsctl is modified to add msg.default.{attrs,bg,fg} and msg.kernel.{attrs,bg,fg} to the display part, so that colors can be changed after boot. Tested on NetBSD/i386 with vga (and vga in mono mode), and on NetBSD/mac68k. No objections in tech-kern@.

/* $NetBSD: wsemul_vt100var.h,v 1.9 2004/07/28 12:34:05 jmmv Exp $ */
First cut on a VT100 emulation. It should be able to parse escape sequences up to VT300, but not everything is implemented. Most notably, there is no font handling - all displayable characters are handed to the graphics driver. To solve this, a serious interface change to the graphics driver is needed (Unicode?).

Add a concept of the `background attribute'. This is the same as the current attribute, but has all non-color flags turned off. Use this when doing erasure, as this allows us to optimize repainting in curses. XXX The way the default attribute is handled is totally bogus and needs to be fixed.
