'+cur' means this driver includes a hardware cursor section;
'=cur' means this driver is only for a hardware cursor.

You may also want to make the following changes to vganvidia.c to make
the cursor behave 'properly' at the screen edges.

The only other problem I see is that when you move the cursor around
continuously there's sometimes a flash of an uninitialised (mostly white)
cursor. Maybe it's just my card:

	0xC00A2="NVIDIA TNT2 Model 64 BIOS V2.05.13 "	# NVIDIA TNT Model 64

All in all, a nice contribution, thank you.

 Well the xfree86 drivers disable the cursor when changing the position,
so maybe it should do the same (just like in nvidiacurload - lowest bit in
crt 0x31).

 Good to see it works for someone other than myself.

Probably it was protected (the little window) against write. I
have experienced it to fail silently. I seems to work but it
doesn't really write.

I only have a simple V3400TNT card that I hope to try (finally?)
tonight at home. When it works I will post the bios string.

(Yesterday I did something wrong when putting the boot disk on floppy
 using 'cat ndisk > /dev/fd0disk': the disk still contained the old
 contents; today I did the same and now the cat worked. yesterday
 I did have the floppy mounted, but unmounted before the unsuccessful
 cat, I'm almost sure. Still, could that explain the difference?)

It works, it works!!!. It was the missing entry
in data.c after all.

It works fine for me in 1280x1024. In other
modes the "virtual screen" is greater than
the physical. Anyway, thanks a lot Nick, now
I can use Plan9 at home!!.

Anyone has tried it for Ultra TNT??. What
would it take to add 16 bits support??.
Just in case I have some spare time...

I have encountered the same problem as you have.
I think you also have to edit /sys/src/cmd/vga/data.c
to add lines similar as the others.
(I have made a new boot/install disk, but not yet tried to use it)

> Added vganvidia.$O\ to pcdisk
Shouldn't you add something like 'vganvidia +cur' to pcdisk (.$O)?
I'm confused about the meaning of the '+cur' and '=cur' that follow
the vga* lines in the confguration files.

> Added extern Ctlr nvidia; and
> extern Ctlr nvidiahwgc; to vgadb.h

Hmm... I did only add the extern Ctrlr statements to vga.h
Did not find vgadb.h

About /lib/vgadb: do we need the link=vga line for the nvidia
controller? I noticed some controller(s?) in the file without
such a line.

 Ok, these are the changes I made (relative to the latest update).
Hopefully I havent missed anything. Note that if you want to build the
floppy image, then you should add the same line to /sys/src/9/pc/pcflop as
I did to /sys/src/9/pc/pcdisk.

diff /lib/vgadb /lib/vgadb.orig
299,303d298
< ctlr
< 	0xC0072="Diamond Viper V550"			# TNT
< 	link=vga
< 	ctlr=nvidia linear=1
< 	hwgc=nvidiahwgc

diff /sys/src/9/pc/pcdisk /sys/src/9/pc/pcdisk.orig
72d71
< 	vganvidia		+cur

diff /sys/src/cmd/aux/vga/mkfile /sys/src/cmd/aux/vga/mkfile.orig
40d39
< 	nvidia.$O\

diff /sys/src/cmd/aux/vga/data.c /sys/src/cmd/aux/vga/data.c.orig
47,48d46

Thank you very much, this is just what I needed. You seem to have the same card as a I do. I will tell you it i works for me. By the way, leave the
diff with the c files, it is very useful...

Sorry, I meant vganvidia +cur.

I read somewhere you had to add that the vga line in any controller...

I tried that but it doesn't seem to help. It doesn't happen often under
normal use but it's just enough to make you blink now and then.

[paurea]

I have been trying to make the TNT driver work form my card, but I can't
even get it being used. The message it says is something like

dbctl: "nvidia" driver not found.

I have:
Copied the vganvidia.c supplied to /sys/src/9/pc

Added vganvidia.$O\ to pcdisk

Compiled 9pcdisk.gz

Copied it to an installation disk.


Copied the nvidia.c supplied to /sys/src/cmd/vga

Added nvidia.$O\ to the mkfile of vga

Added extern Ctlr nvidia; and

extern Ctlr nvidiahwgc; to vgadb.h

and extern Ctlr nvidia; to vga.h

Compiled it. Installed it.
An added an entry in vgadb for my
card:

ctlr 0xC0072 "Diamond Viper 550"
     ctlr nvidia
     ctlr nvidiahwgc
     link=vga

Any idea?. Please be detailed, any change means changing the card...

TIA.
