From: Jeremy Fitzhardinge Date: Tue, 17 Mar 2009 00:08:48 +0000 (-0700) Subject: x86-64: non-paravirt systems always has PSE and PGE X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5f241e65f2be4661a33e1937e1c829252a80b2b8;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git x86-64: non-paravirt systems always has PSE and PGE A paravirtualized system may not have PSE or PGE available to guests, so they are not required features. However, without paravirt we can assume that any x86-64 implementation will have them available.
