nisimura 9ab80b75b8 - Fix MX framebuffer size which should occupy 2MB in address range.
- Restore 72Hz interrupt service mistakenly ruined in the previous commit.

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).

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).

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.

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.

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 fec5fef8a5 - Fix an error in cursor color manipulation. 24bit RGB value was mistakenly
assigned to unsigned short variable.
- XXX PMAG-DV is supposed to emit virtical retrace interrupt, which can be
used for colormap/cursor update just like other TURBOchannel framebuffers.

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.

thorpej 29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter.  This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.
