Hi- The cpint modules has a problem running on VM guests that have defined more than 2G storage. The code in question is: .. SAM31 DIAG 0x08 SAM64 ..
If the cpint module is loaded above the 31-bit address space the SAM31 fails with an exception. The kernel function cpcmd() preforms the same function but is build into the kernel so the code is located at an address in side the 31-bit address space. I would like to change cpint to call the cpcmd() function thus eliminating the DIAG call in cpint and avoiding the problem. Is it safe to assume that the cpcmd() function will always be loaded into the lower address? Another suggestion: Starting in VM 4.3 the DIAG 0x08 is allowed in the 64-bit mode so the SAM31 is not needed. However, this would require adding logic to check the version of VM if >2GB. This requires a DIAG 0x00 instruction this instruction has the same restriction as DIAG 0x08, so catch 22.
