target-s390x: wire up DIAG IPL in TCG mode DIAG IPL is already implemented for KVM, but not wired from TCG. For that change the format of the instruction so that we can get R1 and R3 numbers in addition to the function code. The diag function can change plenty of things, including CC, so we should enter with a static CC. Also it doesn't set the value of general register 2 to 0 as in the current code. We also need to exit the CPU loop after a reset, which means a new PSW. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>

target-s390x: rename helper flags Rename helper flags to the new ones. This is purely a mechanical change, it's possible to use better flags by looking at the helpers.

target-s390x: basic PER event handling This patch add basic support to generate PER exceptions. It adds two fields to the cpu structure to record for the PER address and PER code & ATMID values. When an exception is triggered and a PER event is pending, the two PER values are copied to the lowcore area. At the end of an instruction, an helper is checking for a possible pending PER event and triggers an exception in that case. For that to work with branches, we need to disable TB chaining when PER is activated. Fortunately it's already in the TB flags. Finally in case of a SERVICE CALL exception, we need to trigger the PER exception immediately after. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>

target-s390x: PER successful-branching event support For the PER successful-branching event support, we can't rely on any QEMU infrastucture. We therefore call an helper in all places where a branch can be taken. We have to pay attention to the branch to next case, as it's still a taken branch. We don't need to care about the cases using goto_tb, as we have disabled them in the previous patch. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>

target-s390x: PER instruction-fetch event support For the PER instruction-fetch, we can't use the QEMU breakpoint infrastructure as it triggers for a single address and not a full address range, and as it actually stop before the instruction and not before. We therefore call an helper with the just fetched instruction address, which check if the address is within the PER address range. If it is the case, an event is recorded and will be signaled through an exception. Note that we implement here the PER-3 behaviour, that is an invalid opcode is not considered as an instruction fetch. Without PER-3 this behavious is undefined.
