nisimura e78e58a7b8 - Fix TX 8bpp framebuffer size, which occupies 2MB.
- Rework CX RAMDAC register access like as other TC framebuffers.

nisimura c03616646c - Fix TX 66Hz interrupt handling. Verified ok with PMAG-JA as an 8bpp
console.  XXX troubles in cursor color.
- Typo in comments of MX.

nisimura 09a2fed6f9 - Show 1bpp for MX during configuration stage.
- Replace memory layout 'struct' with array/pointer access.

nisimura 1d082ddc15 - Sweep abit preparing for code merge to have common 'vdacops' across
various graphics cards.

nisimura ed7699b360 - Unnecessary to have '#include <machine/autoconf.h>' for those. 1999-03-29 07:22:02 +00:00
mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the
header files as UVM still uses (most of) these.

nisimura f85c9832ac - Fix cursor image validity check error in set_cursor(). 1999-03-01 02:45:04 +00:00
thorpej 8ce7166aa3 __pmax__ -> pmax, like other ports. 1999-01-15 23:29:55 +00:00
drochner 1eba733d91 remove dummy "load_font" entries 1999-01-11 21:35:54 +00:00
nisimura 8bb7627336 - Fix typos in commentary description. 1998-12-14 02:45:51 +00:00
mrg db3051d720 fix problems in many d_mmap routines:
- returned EOPNOTSUPP rather than -1.
	- no check for negative offset.
many of these fix potential security problems in these drivers.


XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
	paddr_t (*d_mmap) __P((dev_t, off_t, int));

by someone!

nisimura 4184d87669 - Fix cursor image handling bugs escaped in last commit. 1998-11-18 12:26:31 +00:00
nisimura 9d716ec821 - Fix many errors in cursor image manipulation. Hardware expect 2
bit/pixel format, not planer format.  Assign MSB for cursor mask and
LSB for cursor image, where 10 means mask color and 11 for image color.
Image bit order of Bt431 and Bt459 are opposite to MIPS/Alpha processors
while IMS G332 and DC503 (PCC) are indentical.
- Assume that cursor images are 32 pixel padded as ULTRIX/DU ws interface
do.  It's natural to X server.
- XXX Vast majority of codes are duplicated between mfb<->tfb and cfb<->sfb.
Code sharing might be achieved in the context of TGA/SFB+ merge.

nisimura e29350c92c - Introduce MI NWSCONS drivers for TURBOchannel framebuffer option cards.
N.B., Digital UNIX never supports neither PMAG-AA (mfb) nor PMAG-BA (cfb)
for TC Alphas.  PMAG-DV (xcfb) is Personal DECstation built in.  All should
be good for console, but need much works for cursor/colormap completeness.
