this graphics card was supported in the first alpha release but it's not anymore, now i'm using the rev:36447 and i was surprised to see that it's using the vesa driver, although this card was well supported?

is this ticket has been fixed or it hasn't been seen yet?i'm not pushing or anything,but it's been here for 3 days now and it hasn't been assigned to anyone. strange that my pc now uses the vesa accelerator, no 2d acceleration at all and is a bit dark.

taking a best guess & re-assigning to Gerald.

This is not an s3 video chip; it is a Via chip. On line 14 of the syslog, the OEM string identifies it as a "VIA P4M800 PRO" which should be supported by the VIA driver which was written by Rudolf Cornelissen; thus, this bug should be assigned to Rudolf instead of Gerald Zajac.

Noted, thanks.

But that also means that this chipset was never supported; IOW this renders the ticket invalid, as there is no regression.

if you look further in the syslog lines 311 up to 313 you'll see that it's reported as a s3 unichrom pro,that was reported also by the sreen preflet on the R1A1.(BTW s3 is owned by via since a couple of years now)that it explaines maybe the confusion about why it is reported differently in the line 14 of the syslog.

The VIA driver does have an entry for this card, only it is commented out. The entry was added in changeset:23754.

any idea why it's been commented out?it was working quiet stable! and are we gonna see it again in the next releases?

comment:9 Changed 9 years ago by idefix

As you can see, changeset:23754 is two years old and thus pre-dates Alpha 1. So your card shouldn't have worked with that release either.

What you can try though, is to uncomment that line, build the driver and test if it works with your card.

Looking closely at hrev23754, I see the commented line was *added*, not commented out.

comment:11 Changed 9 years ago by stippi

No other changes to that file since that revision, BTW. (svn log)

That's what I tried to say in comment:7, but I probably could have worded that better...

Though small there's a certain chance that Axel still knows, why he added the line like that. :-)

That's an easy one for my eidetic brain: I have a system with that chipset, and had a look if it could easily be made to work. Which was not the case, which I left it commented out. Oh, and it was rainy that day ;-)

comment:15 Changed 9 years ago by rudolfc

Actually, I did write the VIA driver in Haiku svn. I think I never finished it for acceleration though.

I had a VIA Nimble V5 from Yellowtab for building and testing the driver. This had a CLE66 chipset (unichrome) which worked OK with the driver. In the beginning I added recognition for K8M800 Unichrome Pro and P4M800 Pro (VT3344) because I thought they would work the same as far as my driver was concerned.

Since I got some negative reports from users I disabled the P4M800 support, and I doublt the K8M800 support is OK. I never got my hands on these respective chipsets so I could not correct the problems.

In the end I stopped development and some time later Axel and I started mailing about the Nimble. I then donated this Nimble to Axel, so he has indeed some hardware ;-)

Bye!

Rudolf.

Summary: the s3 unichrom pro is not supported anymore?the VIA P4M800 PRO/S3 UniChrome Pro is not supported anymore?

comment:17 Changed 3 years ago by khallebal

I think Rudolf fixed this ticket? and i don't this HW anymore, so if it is fixed, please close.

I'll have a look for the status.. Thanks!

hrev52014 reviewed. Can close this ticket per reporter request (ticket and card are now 8+ years old).

comment:20 Changed 11 months ago by rudolfc

The card is a vendor 1106: VIA Technologies, Inc. device 3344: CN700/P4M800 Pro/P4M800 CE/VN800 [S3 UniChrome Pro]

This ID $3344 is not in the driver, so the card is currently not supported. Since I _did_ add explicit, and tested OK, K8M800 support, one could add the ID as a new test to see if this card behaves this time (previously it did not, just like K8M800).

K8M800 was added because I stumbled upon this card by chance.

If noone can actually test P4M800 The ID should best not be added.

Closing ticket. Please reopen if someone has acces to this card and runs Haiku on it..

Rudolf.
