And I also You dont see any interaction between the cpu hotplug and the one tokunaga-san is posting because they can be done independently. So here is the scope, i will try to keep it short and sweet.! CPU hotplug - Ashok(intel for IA64) Primarily does logical cpuonline/offline support to work with base support released by rusty from 2.6.5 PPC64 - Joel Schoop, Vatsa (IBM), x86 (Rusty/Vatsa) ACPI support for cpu hotplug - Anil Keshavamurty (intel) base line emulation and ACPI patches are ready, we are reviewing it internally and it should make its way to acpi lists sometime in the next 2 weeks. (on major changes.. just extensions to acpi already in base kernel) Memory hotplug - Dave Hansen et all (mostly IBM) + Matt Tolentino (Intel) Goto-san (fujitsu) + Takahashi/Iwamoto San (VA Linux) disscussed in lhms (sourceforgelist) Matt is also co-ordinating ACPI based memory hotplug support for the work that he requires as necessary. Node Hotplug support - Tokunaga-san (fujitsu) mostly concentrating on ACPI based numa node hotplug. This work is independent of rest of the hotplug (atleast mostly) and would invoke other module hotplug code as required. (roughly @10000 ft level) Iam not sure what specifically you are looking for, please post your specific request to the appropriate lists and iam sure you will get hooked up. lhcs - cpu hotplug list lhms - memory hotplug lhns - newly launched node hotplug all of them hosted from sourceforge. Hope this helps. > just noticed the thread on lkml by Keiichiro, with comments from Dave, > mentioning Matthew, hinting at additional interactions that might be > desirable between various efforts here.
