MAME now fully open source - time for Voodoo 3 emulation in WinUAE?

[Sandro]

maybe on winuae is possible to use a glide wrapper to emulate a vodoo card ?
like those used on the ULtraHLE nintendo 64 emulator which was originally coded to use vodoo cards
some wrappers are open source

[Toni Wilen]

It has no use whatsoever for hardware emulation.

[thellier]

Once again: IMHO implementing a radeon emulation in WinUAE will be a lost of time.
But implementing a working uaenative.library (I mean one that will really allow OS4 ppc / x86 calls) will allow me to port Wazp3D to WinUAE/OS4/ppc

But I dont know if Toni will implement such uaenative.library ...

This is about hardware emulation. Don't try to annoy me by talking about native stuff in this thread! It is extremely boring and uninteresting.

[Seiya]

i think the best implementation is to make something similar to QuarkText or dosbox or PcEM 3dfx emulation

Sorry for the wild bump, but what you asked for just happened - PCem v17 is out, with Voodoo 3 emulation included

Time for Mediator + Vooodoo 3 in WinUAE?

[Toni Wilen]

I expected Voodoo 3 emulation earliest in next year..

Technically adding support should be much simpler (than existing Amiga RTG boards) because Voodoo 3 is normal PCI board, "simply" hook it up with existing PCI bridge emulation.

I'll check later this week..

Voodoo3 merged from PCem. Mediator Picasso96 driver configures it (sane looking PCI BAR address space settings). For some reason BIOS ROM is also required, driver apparently needs it to read some manufacturer/board specific config information? More work to do..

Mediator pciinfo output with Voodoo 3 installed would be nice to see.

I will sculpt a statue for you if this is done :-)
you just have to choose a place in rome

Here's one:

Pci Device 4:
   VendorID: $121a
   VendorName: 3Dfx Interactive, Inc.
   DeviceID: $5
   DeviceName: Voodoo 3
   ClassCode: $30000
   RevisionID: $1
   InterruptPin: 0
   SubsystemVendorID: $4
   SubsystemID: $0
   MemSpace0: $8a000000 - $8bffffff
   IOSpace2: $eb6300 - $eb63ff
   IOSpace3: $eb6400 - $eb64fb
   RomSpace: $88200000 - $8820ffff

Bonus:

Pci Device 6:
   VendorID: $121a
   VendorName: 3Dfx Interactive, Inc.
   DeviceID: $9
   DeviceName: Voodoo 4 / Voodoo 5
   ClassCode: $30000
   RevisionID: $1
   InterruptPin: 4
   SubsystemVendorID: $121a
   SubsystemID: $5
   MemSpace0: $90000000 - $97ffffff
   MemSpace1: $98000000 - $9fffffff
   IOSpace2: $eb6300 - $eb63ff
   RomSpace: $88400000 - $8840ffff

[Toni Wilen]

Hmm.. Single memspace but pcem has memspace0 and memspace1, also pcem has single iospace but your output has two iospace. Strange.

Is that Voodoo 3 3000 or something else?

[Toni Wilen]

It works!

More information tomorrow/sunday..

NOTE: "it works" means WB screen opens. 3D is not included (should be quite obvious by now!). The main point is to have hardware emulated display card that supports at least full hd 32-bit resolution without running out of VRAM (like with PicassoIV).


btw, above Voodoo 3 pciinfo output can't be right. Official Voodoo 3 documentation also says it has 2 memory mapped regions and single IO space and ROM space. But it could be also pciinfo bug because emulated pciinfo output is also weird:

Pci Device 1:
   VendorID: $121a
   VendorName: 3dfx Interactive Inc
   DeviceID: $5
   DeviceName: Voodoo3 All Voodoo3 chips, 3000
   ClassCode: $30000
   RevisionID: $1
   InterruptPin: 2
   SubsystemVendorID: $121a
   SubsystemID: $3a
   MemSpace0: $50000000 - $51ffffff
   MemSpace1: $52000000 - $53ffffff
   IOSpace2: $44c06000 - $44bf60ff
   RomSpace: $54000000 - $5400ffff

Note IOSpace2: start is higher than end.. It is correctly configured because display works. (DeviceName is normal, it comes from S:Vendors.txt). Using emulated A4000 Mediator.
