I assume this is > still the case. There's a gotcha with KVA_PAGES. On a standard kernel, there are 1024 Page directory slots. By default we use 256 of them for 1 out of 4GB. On a PAE kernel, there are now 2048 page directory slots. The same 1:3 split requires a default KVA_PAGES of 512. So if you want to increase KVA beyond the default 1GB, do not forget to take the scaling into account. > Cheers, > Daniel -- Peter Wemm - peter_at_wemm.org; peter_at_FreeBSD.org; peter_at_yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5Received on Tue Jun 15 2004 - 18:58:44 UTC
