I wrote a paged-buffer class with selectable features such as wired, virtual-ring, shared, etc. During starting of an audio device, I first wire down and touch each page of the I/O ring buffers; when the device stops, they are unwired and/or freed. Any buffers that my audio/DSP and MIDI time-constrain threads utilize, I wire when in use. There are a few MacFOH users who only have 128 to 384 MB of RAM installed, and nobody has reported any thrashing issues. - mlock/munlock is available for user space code The caveat is that they must also be executable, to be wired from user space. -- Shaun Wexler MacFOH http://www.macfoh.com This email sent to site_archiver@lists.apple.com
