Hi, I'd like to ask how stable the current highmem support is, as of linux 2.6.16-rc6. The host runs 2.6.15.6 + skas, the guest runs 2.6.16-rc6, and in menuconfig it states that highmem support is currently unstable.. I'd like to run several umls with 2-4G ram... comments? :) Thanks in advance, Zoltan NAGY, Software Engineer |

Until about 2,75G it's sufficient to disable TT mode (and thus run in SKAS0 or SKAS3 mode) and enable static linking. Uml won't use the HIGHMEM mechanism but it will access that much memory anyway (the way used is similar to 4G/4G - SKAS mode runs always like that). Indipendently of UML, if you want a process on the host to use more than 3G, you need to apply the 4G/4G patch (by Ingo Molnar) on the host or to use an x86_64 host. UML should be able to take advantage of this, but I don't know if anybody tested it. > comments? :) > Thanks in advance, > Zoltan NAGY, > Software Engineer -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
