>My guess is that the TLB has not been updated yet. That save performance as the unallocation can wait until all CPs running in the address space have had normal interrupts to process the changes.
The unallocation can wait until RSM sees a need to put them onto the available frames queue. It may well be that such a frame will be reused upon a later GETMAIN, when VSM assigns the same virtual address, I would understand. The APAR decribes that marking frames as freemained frames avoids signaling all processors, which does not scale well with the large number of processors in z13 and newer machines. It probably avoids updating the TLBs. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
