Problem summary
**************************************************************** * USERS AFFECTED: zVM users with zEDC Express or * * 10GbE RoCE Express features. * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** With the PTF for APAR VM65417, z/VM V6.3 guests will be allowed to dedicate PCIe adapters to their virtual machines. Note: For specific information about enabling and configuring z/VM for guest exploitation of PCIe adapters see the following website: http://www.vm.ibm.com/zvm630/apars.html Note: DVF APAR VM65572 and TCPIP APAR PI20509 are required for this support if DVF and/or TCPIP is used on your system. The minimum hardware requirement for the zEDC Express and 10GbE RoCE Express features is a zEnterprise EC12 or BC12 at driver level D15 with a minimum bundle level. At the time of the closing of this PTF, not all of the required firmware updates are available. See the PSP bucket for availability information of required firmware. z/OS V2.1 guests (with required PTFs) running under z/VM V6.3 can exploit the zEDC Express and 10GbE RoCE features. See the PSP bucket for specific details. - zEDC Express feature IBM zEnterprise Data Compression (zEDC) for z/OS V2.1 and the zEDC Express feature are designed to support a new data compression function to help provide high-performance, low-latency compression without significant CPU overhead. This can help to reduce disk usage, provide optimized cross-platform exchange of data, and provide higher write rates for SMF data. - 10GbE RoCE Express feature The term RoCE refers to Remote Direct Memory Access over Converged Ethernet. The 10 Gigabit Ethernet (10GbE) RoCE Express feature is designed to help reduce consumption of CPU resources for applications utilizing the TCP/IP stack (such as WebSphere Application Server accessing a DB2 database). Use of the 10GbE RoCE Express feature is designed to help reduce network latency with memory-to-memory transfers utilizing Shared Memory Communications-Remote Direct Memory Access (SMC-R) in z/OS V2.1. It is transparent to applications and can be used for LPAR-to-LPAR communication on a single system or server-to-server communication in a multiple-CPC environment.

Comments
Updated publications can be found at the IBM Publications Center at http://www-05.ibm.com/e-business/linkweb/ publications/servlet/pbi.wss For latest enabling and configuration information see the following website: http://www.vm.ibm.com/zvm630/apars.html This information supercedes what is found in the publications. For more information about guest support for PCIe functions, see z/VM CP Planning and Administration, Chapter 16 - "Using PCIe Functions for z/VM Guests". The following system configuration statements have been updated for this support: - FEATURES - STORAGE The following CP commands have been added for this support: - DEFINE PCIFUNCTION - DELETE PCIFUNCTION - DETACH PCIFUNCTION - LOCATE RPCI - LOCATE VPCI - MODIFY PCIFUNCTION - QUERY IOASSIST (The function of this command is similar to but different from the QUERY IOASSIST command that was removed in V5.1.) - QUERY PCIFUNCTION - QUERY VIRTUAL PCIFUNCTION - SET IOASSIST (The function of this command is similar to but different from the SET IOASSIST command that was removed in V5.1.) - VARY PCIFUNCTION The following CP commands have been updated for this support: - ATTACH - DEFINE CHPID / PATH - MONITOR - QUERY CHPID - QUERY FRAMES - QUERY MONITOR - QUERY TRFILES - QUERY TRSOURCE - RESET - SET CPTRACE - TRSOURCE ENABLE - TRSOURCE ID - VMRELOCATE PCIFUNCT has been added to the list of restricted user IDs. The following CP monitor records have been added for this support: . - Domain 1 Record 27 - MRMTRPCI - PCI function Configuration Data - Domain 6 Record 36 - MRIODPAT - Attach PCI Function - Domain 6 Record 37 - MRIODPDT - Detach PCI Function - Domain 6 Record 38 - MRIODPEN - Guest Enables a PCI Function - Domain 6 Record 39 - MRIODPAC - PCI Activity - Domain 6 Record 40 - MRIODPDS - Guest Disables a PCI Function - Domain 6 Record 41 - MRIODPER - PCI function error - Domain 6 Record 42 - MRIODPAD - PCI function added to the system - Domain 6 Record 43 - MRIODPDL - PCI function deleted from the system - Domain 6 Record 44 - MRIODPMD - PCI function program controls modified - Domain 6 Record 45 - MRIODPON - Real PCI function varied on - Domain 6 Record 46 - MRIODPOF - Real PCI function varied offline The following CP monitor records have been updated: - Domain 0 Record 3 - MRSYTRSG - Real Storage Data (global) - Domain 1 Record 4 - MRMTRSYS - System Configuration Data - Domain 1 Record 7 - MRMTRMEM - Memory Configuration Data The following DIAGNOSE code has been updated for this support: - DIAGNOSE Code X'2AC' Trace codes in the range 1200 - 123F have been added for this support (For more information about these trace codes, see z/VM: Diagnosis Guide). The following dynamic I/O return codes have been modified for adding, deleting, or changing a PCI function: - 0106 - 0107 - 010A - 010D - 010F - 0110 - 0112 - 011C - 011D
