nisimura 72de8abb0c Arrange loop invariants and fix comment description error. 1999-10-08 02:08:15 +00:00
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.

mrg f4efaa9db4 add AV300-AA video capture card & PNTNV-AA NV-RAM card. 1999-09-26 09:18:53 +00:00
nisimura ffe9ca742d Add 'sfbreg.h' to the list of files installed in /usr/include/dev/tc/. 1999-09-24 01:01:23 +00:00
nisimura 1f50d00cc1 Add one new dispaly type for DEC TC TX 8/24bpp framebuffer. Currently acts 
as an 8bpp pseudo color device.

ad 697eb331c5 Ammend some entries. 1999-09-18 01:46:01 +00:00
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.
 1999-06-23 01:58:22 +00:00
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 1d082ddc15 - Sweep abit preparing for code merge to have common 'vdacops' across 
various graphics cards.

nisimura b2c6b9a41d - Nuke debugging aids mistakenly committed. 1999-04-30 09:43:23 +00:00
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.

mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

jonathan ef79649fc1 MI ioasic softc and child-device structs, gc duplicate struct definitions. 
Add MI ioasic functions, but dont enable on alpha until tested.

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.
 1999-03-04 01:39:04 +00:00
nisimura e19cedee17 - Make sfb_emulops standard feature of sfb wscons. Scrolling is now 
acceptable.  Still lacks of horizontal copy and glyph rendering with
SFB ASIC assistance.  TGA could be benefitted in the similiar way.
 1999-03-02 00:22:42 +00:00
nisimura f85c9832ac - Fix cursor image validity check error in set_cursor(). 1999-03-01 02:45:04 +00:00
nisimura d6715660b7 - Introduce the first cut of faster wsdisplay_emulops exploiting SFB 
accelerator potential.  Need more work to finish replacing rcons.
Premilinary tests were done with DECstation and TC Alpha.
 1999-02-23 06:34:49 +00:00
nisimura c07be2882b - Make sure SFB ROP register initialized with value 3. 
- Turn off video signal during hardware initialization.
