Best way to lock malloc'd memory in kernel
I'm writing a device driver for plex86 (the FreeMWare virtual machine software), and have a buffer that needs to be non-pageable. It was malloc'd with the malloc(size, type, flags) kernel malloc function. What's the best way to make this memory unpageable?

I didn't realize that, I suppose I should have RTFM'ed a bit more before asking, but I just kind of assumed (we all know what that does) that memory malloc'd in kernel mode was pageable. I guess I should ask whether that holds true for kernel modules as well, because that's what I'm actually writing.

I guess I should ask whether Yes, well it would be nice to have some kernel memory pageable but.. that holds true for kernel modules as well, because that's what I'm actually writing. Yes, writing a module is no different than writing for static kernel code. --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
