jmcneill 6984d2ca99 Fixup a performance problem in rasops_copyrows that I introduced during 
the shadowfb merge.

dsl 6f0f9f8763 Make almost everything #include <sys/bswap.h> instead of <machine/bswap.h> 
The bswap.h and endian.h files are all rather incestuous, but I want to
get the constant folding stuff into one place - sys/bswap.h

petrov 2f82eaf699 Check character if it in font limits before drawing it in rasops8_putchar 
functions.
 2004-03-05 08:33:53 +00:00
uwe aa4c79f23b For the rasops-drawn cursor the fg/bg indices are bit inverted, so 
provide complimentary colors in the upper 16 entries.

uwe c6aa061dfa In rasops_copycols change bcopy to memmove. In that particular place 
the src and dst are very likely to overlap, so using bcopy causes
garbage to be displayed

ad b89e39b91a Reorganise the wsfont stuff slightly so that multiple display adapters 
with different bit/byte order requirements can co-exist happily.

uwe 6e320d03b8 Undo previous that incorrectly byte-swaps stamps for little endian 
machines when RI_BSWAP is *not* set.  Redo my original fix to directly
build stamps in desired endianness instead of calling bswap32().

lukem ecb81c3f6d - convert usage of "defopt" to "defflag" where the relevant option does 
not support a value (e.g., it's to be used as "options FOO" instead of
  "options FOO=xxx"). options that take a value were converted to
  defparam recently.
- minor whitespace & formatting cleanups

jdolecek 372e5956ef Only install headers which are actually used by our userland. This 
saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.

I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.

nathanw 54caa65cf6 Correct the ri_xorigin calculation for the RI_CENTER case again. 
Original calculation (bits += (ri_stride - ri_emustride) / 2) was
incorrect because stride may be wider than visible width.

Fix in 1.33 (bits += (ri_width - ri_emustride) / 2) was incorrect
because units do not match; "bits" and "ri_emustride" are in bytes,
but "width" is in pels. Works by accident for 8bpp displays.

Change to bits += ((ri_width * bpp / 8) - ri_emustride) / 2
to correctly account for visible width and bpp.
