Yesterday I forgot to post a link to the feature request that nVidia made for FreeBSD people.

NVIDIA FreeBSD kernel feature requests (At the foot there is a summary if you don't want to read all)

If the nVidia drivers were open, such request would be unneeded or the kernel is really lacking of means for some features that doesn't look really extraordinaire?

Some of the problems do lay with nVidia, especially since the nVidia X driver doesn't use DRI or the currently available kernel drm drivers (which the open source X drivers do).

However those issues/proposals raised are also extremely helpful with other drivers as well, so it's in the overall long term benefit to implement those requests made by nVidia...

eg. like the ability to cleaning handle devices limited to 32bit DMA address ranges, on 64bit architectures or systems with more than 4GB of RAM.

PS. Is FreeBSD 7.0 implementing X.org 7.2 or 7.3?

It's running 7.3 right now.

Loco: kernel is really lacking of means for some features that doesn't look really extraordinaire. They need to set precise type of memory cache, but BSD doesn't provide way to specify cache of memory.

For that reason MS has beautiful MmAllocateContigousMemorySpecifyCache()

configmalloc?

Technically: Win95 and Win98 were 32 bit protected mode DOS using FAT.
WinNT was true 32 bit protected and utilized NTFS
WinXP, Vista, 7 and 8 all possess 32 bit and 64 bit with x86_64 Wow compatibility layers (except XP*) to sequentially upgraded kernels and NTFS.

*XP 32 and 64 bit were strictly 32 or 64 bit if I'm not mistaken.

Linux uses a dos format.

UNIX style BSD systems use C calling styles. System interrupt with all arguments on the stack.

LINUX is nothing like UNIX contrary to popular belief, if it's comparable to anything it would be Win98 interfacing wrapping a 32/64 bit protected mode kernel.

BSD originally based on UNIX has evolved considerably, but still behaves like UNIX.

Conclusion: Microsoft Windows is Windows, Linux is Linux and UNIX is UNIX.

Just because the GNU project wrapped their brand around UNIX tools like VIM porting them over to Linux does not make Linux Unix. Lots o' free books out there on UNIX system design and theory -- read one.

It is never too late for wisdom.
