2017-10-06s390x/tcg: make STFL store into the lowcoreDavid Hildenbrand
Using virtual memory access is wrong and will soon include low-address protection checks, which is to be bypassed for STFL. STFL is a privileged instruction and using LowCore requires !CONFIG_USER_ONLY, so add the ifdef and move the declaration to the right place. This was originally part of a bigger STFL(E) refactoring.

2017-10-06s390x/tcg: add basic MSA featuresDavid Hildenbrand
The STFLE bits for the MSA (extension) facilities simply indicate that the respective instructions can be executed. The QUERY subfunction can then be used to identify which features exactly are available. Availability of subfunctions can also vary on real hardware. For now, we simply implement a CPU model without any available subfunctions except QUERY (which is always around). As all MSA functions behave quite similarly, we can use one translation handler for now. Prepare the code for implementation of actual subfunctions. At least MSA is helpful for now, as older Linux kernels require this facility when compiled for a z9 model. Allow to enable the facilities for the qemu cpu model.

Since we require all registers saved on input, read R0 from ENV instead of passing it manually. Recognize the specification exception when R0 contains incorrect data.

2017-06-23target/s390x: Implement idte instructionDavid Hildenbrand
Let's keep it very simple for now and flush the complete tlb, we currently can't find the right entries in our tlb, we would have to store the used tables for each element. As we now fully implement the DAT-enhancement facility, we can allow to enable it for the qemu CPU model.

2017-06-23target/s390x: implement mvcos instructionDavid Hildenbrand
This adds support for the MOVE WITH OPTIONAL SPECIFICATIONS (MVCOS) instruction. Allow to enable it for the qemu cpu model using qemu-system-s390x ... -cpu qemu,mvcos=on ... This allows to boot linux kernel that uses it for uacccess. We are missing (as for most other part) low address protection checks, PSW key / storage key checks and support for AR-mode. We fake an ADDRESSING exception when called from problem state (which seems to rely on PSW key checks to be in place) and if AR-mode is used. user mode will always see a PRIVILEDGED exception. This patch is based on an original patch by Miroslav Benes (thanks!).

2017-06-06target/s390x: Fix some helper_ex problemsRichard Henderson
(1) The OR of the low bits or R1 into INSN were not being done consistently; it was forgotten along all but the SVC path. (2) The setting of ILEN was wrong on SVC path for EXRL. (3) The data load for ICM read too much. Fix these by consolidating data load at the beginning, using get_ilen to control the number of bytes loaded, and ORing in the byte from R1. Use extract64 from the full aligned insn to extract arguments. Pass in ILEN rather than RET as the more natural way to give the required data along the SVC path. Modify ENV->CC_OP directly rather than include it in the functional interface. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
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.
