For UV and format 4 SIE tests we need to handle the following PGM exceptions: 0x3d Secure Storage Access (non-secure CPU accesses secure storage) 0x3e Non-Secure Storage Access (secure CPU accesses non-secure storage) 0x3f Mapping of secure guest is wrong Signed-off-by: Janosch Frank <frankja@linux.ibm.com> --- lib/s390x/asm/arch_def.h | 3 +++ lib/s390x/interrupt.c | 3 +++ 2 files changed, 6 insertions(+)
