* Move target-* CPU file into a target/ folderThomas Huth2016-12-201-931/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

* target-s390x: wire up I/O instructions in TCG modeAlexander Graf2015-06-171-11/+11
| | | | | | | | | The code handling the I/O instructions for KVM decodes the instruction itself. In TCG mode also pass the full instruction word to the helpers.

* target-s390x: wire up DIAG IPL in TCG modeAurelien Jarno2015-06-171-1/+1
| | | | | | | | | | | | | | 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: implement load-and-trap facilityAurelien Jarno2015-06-051-0/+10
| | | | | | | | | | | At the same time move the trap code from op_ct into gen_trap and use it for all new functions. The value needs to be stored back to register before the exception, but also before the brcond (as we don't use temp locals). That's why we can't use wout helper.

* s390x: Implement SAM{24,31,64}Alexander Graf2014-11-051-3/+3
| | | | | | | | | | | | | | | | The SAM instructions simply change 2 bits in PSW.MASK to advertise the current memory mode. While we can't fully guarantee that 31 bit mode (or even remotely 24 bit mode) actually work correctly, we don't check whether lpswe modifies these bits, so we shouldn't keep the guest from executing SAM instructions either. This patch implements all SAM instrutions with their actual PSW changing semantics, making more recent Linux kernels boot properly which do issue a SAM31 call during early boot.
