riastradh | Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.
To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

macallan | add support for loading fonts in vcons and subsequently resizing screens
- drivers can use this by setting VCONS_LOADFONT and WSSCREEN_RESIZE
- each vcons screen can now have its own font and geometry
- while there, add support for xterm's ESC[18t to report the text buffer's
size
With this tou can:
wsfontload -N foo /usr/share/wscons/fonts/flori.816
wsconsctl -dw font=foo
currently this is limited to drivers that don't use the glyph cache, like genfb

-rename the "KS_GROUP_Ascii" key symbol category to "Plain" because
this is what it meant all the time -- it includes characters >127
-delegate translation of all key symbols >127 to the terminal emulation
layer -- formerly everything non-special was passed to the tty subsystem
directly, involving truncation to a "char", which effectively meant
some ISO-1 assumption

drochner | branches: 1.6.8;
define a "clear screen" command to the emulator and complete the
emulation's "reset" implementations as far as useful
|
| 1.5 |
| 20-Jun-1998 |
drochner | Change the calling interface for text output (to the graphics driver)
to take a single character at a time, where the character is an "int" now.
The old interface (took a string) was never called with more than 1
char to print, and the "int" allows us to handle charsets cleanly.

| 1.4 |
| 20-Jun-1998 |
drochner | add some more ASCII definitions, move NP->FF for consistency
|
| 1.3 |
| 15-Jun-1998 |
drochner | Move the translation of keypad and function keys into the realm of the
terminal emulation. For this, change the interface to wsdisplay_kbdinput()
to take a "keysym_t" as argument. From there, the code is handed to the
appropriate emulation module via a new entry point: "translate".
Nuke the ioctls dealing with global assignment of character sequences
to keypad/function keys.
The "sun" emulation works much better now!
|
| 1.2 |
| 14-May-1998 |
drochner | Simple screen attribute handling for wscons.
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
