64 bit kernel-xen.
I found this in xen sources:
/* Simple continuous piecewiese linear function:
* max MiB -> min MiB gradient
* 0 0
* 16 16
* 32 24
* 128 72 (1/2)
* 512 168 (1/4)
* 2048 360 (1/8)
* 8192 552 (1/32)
* 32768 1320
* 131072 4392
*/
Why this is not provided in documentation or on web site?
