nisimura 5cf97491d8 Add a temporary kludge to recognize PMAGD (HX+) as 'sfb' hoping 8bpp 
configration of it is compatible enough with PMAGB-BA.

nisimura 95c618a810 - Fix bogus cursor drawn by sfb_cursor(). From eye-opening input from R.C. 
Dowdeswell.
- Remove write memory barriers in sfb_copyrows() as dst. is always distant
  enough from src. for copying rows.

nisimura 21636a326b Fill always erased regions with bg color. Fix an issue revealed by 
"print -n '\033[7m'; ls".
 1999-10-22 07:42:05 +00:00
nisimura e470fe0db1 Remove Bt459 register layout exposure. XXX Needs consideration about 
possible merger of SFB+ ASIC and TGA(2)/PCI register definitions.
 1999-10-20 02:44:48 +00:00
nisimura fd3561cc02 Preliminary import of 'SFB enhanced' text renderer with many caveats 
to be corrected.  Text drawing is now improved significantly, but;
cursor is drawn incorrectly, copycols() trashes a screen, 'standout
(\033[7m)' results in lines reversed entirely until '\033[0m', and
possibly more issues.  Not multi-colour, 8bpp only this moment.  Costly
write memory barrier instrunctions should be eliminated using framebuffer
address aliasing technique for NetBSD/alpha.

nisimura 9c2fdffad2 SFB video base register is assigned with an inialial value before use; 
according to ULTRIX/OSF1 code.
 1999-10-05 09:13:30 +00:00
nisimura 7fbac8b3cc - Remove defunct codes and arrange consistency between pmax and alpha. 
- Reduce 'ioasic_base' expose.

nisimura 1f50d00cc1 Add one new dispaly type for DEC TC TX 8/24bpp framebuffer. Currently acts 
as an 8bpp pseudo color device.

nisimura 633408472b Use bus_dmamap_load() to obtain 128KB chunk for LANCE merging codes from 
NetBSD/alpha.  Tested ok with DEC3000 and DECstation.
 1999-09-09 06:33:38 +00:00
nisimura de9efb01d3 - Fix an error in cursor image manipulation. I learned a pair of Bt431 
were populated in reverse order from PMAG-A MX ...
 1999-08-25 07:56:22 +00:00
nisimura 0bdb76e5cf - 24bit per pixel TX framebuffer occupies 0x600000. 1999-08-25 02:02:22 +00:00
nisimura 9ab80b75b8 - Fix MX framebuffer size which should occupy 2MB in address range. 
- Restore 72Hz interrupt service mistakenly ruined in the previous commit.
 1999-08-02 06:00:40 +00:00
nisimura e78e58a7b8 - Fix TX 8bpp framebuffer size, which occupies 2MB. 
- Rework CX RAMDAC register access like as other TC framebuffers.
 1999-08-02 04:19:03 +00:00
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.
 1999-07-30 16:23:43 +00:00
nisimura 09a2fed6f9 - Show 1bpp for MX during configuration stage. 
- Replace memory layout 'struct' with array/pointer access.
 1999-06-25 03:33:20 +00:00
nisimura 8dd0e06ba1 - Hide memory mapped VDAC hardware register layouts using the array 
element access instead of C bitfield (hello, BCPL).
- XXX Some TURBOchannel framebuffers might need shutdownhooks().  It
seems not necessarily hardware sprite cursor images are re-initialized
by DECstation PROMs upon exits from kernel.
- XXX It'd be an arguable point to allow user programs to change the
shade of gray freely for pixel value 0 and 1.
 1999-06-24 03:51:14 +00:00
nisimura 463e258cdb - Allow to choose the 'color' of sprite cursor. Only red cmap makes sense. 
- Drop TC Alpha support (OSF/1 and Digital UNIX never supports PMAG-AA).
 1999-06-23 23:48:28 +00:00
nisimura 839bcbbe9f - Fix an error in the depth of PMAG-AA MX. This driver can take 72Hz 
virtical video retrace interrupt and was verified ok on Nanao grayscale
monitor.  XXX seems still confusion/mistake on Bt431 cursor image
manipulation.

mhitch 3adf25374a The extraneous interrupt that seems to occur after a reconnect and a DMA transfer 
starts running can occur on both DMA in and DMA out.  I missed the little comment
in the Mach driver for the DMA out case.  Also, only ignore the interrupt if the
TC is non-zero (to match the Mach driver).
 1999-06-18 05:30:53 +00:00
mhitch cff0f6b1e4 Don't pre-load the identify message into the fifo just just before the command register 
is written.  This significantly reduces, if not eliminates, the problem reported in
PR#5510.  It stops the problem on my 5000/200, and two other people have verified that
it fixes the problem on their 5000/200s.  I'm waiting for confirmation from the PR
originator before closing the PR.

nisimura b14028acc2 - I finally learned CSR_A register of IMS G332 VDAC must be treated as 
write only. Read-motify-write operation breaks its video mode.
- VDAC regiters are now initialized as ULTRIX does.

nisimura 439c3fc0cb - Nuke "PMAD-BA " match string because it is an internal name of IOASIC 
assisted LANCE circuit found only in IOASIC DECstations.  This file is
for 3MAX builtin and PMAD-AA TURBOchannel option card.
