The data from this structure is COPIED by the container. The structure is not directly used nor modified by the container. The address of EDEVBEXT is passed to the container in the SZRBEXT field of each SZREQ request block in a strategy call to uniquely identify an I/O request. A purge request is initiated by passing the same address to HCPSZBPU. This data is serialized by RDEVAIOR (one active I/O at a time). It must be initialized prior to initiating each strategy call. 028C 652 Bitstring 128 EDEVBEXT Start of Buffer Extension BUFFER EXTENSION structure for Native Paging PURGE support This buf ext is needed to distinguish paging I/O requests from normal FBA Emulation requests for purge support. 030C 780 Bitstring 128 EDEVNPBX Start of Native Paging Buf Ext The address overlap list is used by the channel simulator to detect chained READ CCWs that use the same data address. The length of this table should be greater than or equal to the average number of pages processed per READ request. Too low a number will cause fragmentation of strategy calls resulting in performance degradation. The downside to making it bigger is the overhead of searching a longer table as new addresses are added. 038C 908 Signed 4 EDEVACNT Number of entries in EDEVALST 0390 912 Bitstring 16 EDEVALST (120) Address overlap list used only by HCPSZC (mult.
