FreeBSD 6.0 is now Release version and v5.4 the Legacy! :-D

Nice news but we still need this driver

Please, explain this in a deeper way. Are so many the main differences between the amd64 and x86 (32bit) OS code so there's no way to release the 64bit driver but the 32bit one yes?

Thanks and sorry for my english (and for my total ignorance about this. The wait for the drivers is just too long...there's even a windows xp 64 bit edition in the market by now, lol ;-) )

The CC that you see is just another name for gcc. (same as g++).
Just run cc --version to verify it.
I can verify this for 6.0-RELEASE amd64:

Code:
[11:31:46] heracles:~> cc --version
cc (GCC) 3.4.4 [FreeBSD] 20050518

Very curious as to what these "VM" functions nVidia needs are all about. I run BSD exclusively for my dev/testing/production boxes, and not being able to use dual monitors under amd64 is worse than annoying.

Come on nVidia. 64-bit environments aren't the future; they've been the present for a while now.

Please add my vote for freebsd-amd4 driver's. I went high end with my video and my processor... and can't use the advanced video features. Please provide freebsd-amd4 driver's.

Thank you

Here's yet another vote for a FreeBSD-amd64 driver. When/if released, I'll be doing some serious shopping for new gfx cards for all my computers at home and the ones we have at work

Contrary to what is written below, this is not a compiler feature or CPU instruction.

What NVidia wants is control which VM pages can be cached (as in CPU cache) in what way, where the VM pages in question are both pages that are device mapped from the graphics card and pages in annonymously mapped memory.

What I don't understand is why this blocks AMD64 and not i386, to my knowledge the i386 port doesn't have it either.

NVidia also seem to have had earlier Linux drivers without that kind of control.

I also generally fail to see what advantage cache control over annonymously mapped memory brings except a minor performance advantage, respectively saving some work for manual cache control in the driver code when using this memory. For the device mapped memory I can see that it might be required, but for other memory this seems to be microoptimization only. If my assumptions are correct we are blocked on this for a performance advantage in the single-percent area. While I applaud NVidia's desire to make the Unix drivers as fast as the Windows drivers, I personally don't care too much because I have graphics cards that are overkill for what I need. And if I hadn't I would be willing to spend the money for a bigger card than I need if I just get drivers (think of it as paying for the drivers).

Thanks Martin.
Is very interesting that thing you are talking about but if I understand it correctly I also think the i386 port should have the same problem (and we have the driver). I was thinking that their code is just very i386 dependant, not clean. But again there's a Linux 64bit driver for a while and a FreBSD ports should be possible. I can't imagine a real reason for this...my knowledge is very limited
*sigh* I wish the drivers were open source

cheers

One for FreeBSD-amd64 drivers.
I'd love to run FreeBSD AMD64, but for now im stuck with Linux AMD64 ...

I specially registered to make this post:

nVidia guys, we really - really really - need a x86_64 driver for FreeBSD: I see there are x86_64 drivers available for Linux and Solaris... is porting to x64_64 such a big job? Remember, AMD64 is one of the Tier 1 (Fully suported) architectures of FreeBSD.

Many thanks in advance!

The problem is that FreeBSD kernel lacks support from some of the features needed by Nvidia hardware. Let's hope that the latest release of FreeBSD (wich is version 6.0) has these features and the Nvidia developers can finally make a x86_64 driver and a x86_32 driver that supports AGP transfers.

nVidia BSD/i386 driver doesn't support AGP transfers? You sure?
I can't really check it now, but last time I checked, the i386 drivers performed just fine...

Check this thread: http://lists.freebsd.org/pipermail/f...ch/081673.html and watch that hw.nvidia.agp.status.status is disabled. I once read a tread where someone said that Nvidia was working on the AGP problem when an AMD Athlon64 platform was used on with FreeBSD. Let's hope that either this new kernel has all the needed feature or Nvidia releases a new driver.
