2017-07-25s390/cpumodel: remove KSS from the default model of z14Christian Borntraeger
The SIE_KSS feature will allow a guest to use KSS for a nested guest. To create a nested guest the SIE_F2 facility is still necessary. Since SIE_F2 is not part of the default model it does not make a lot of sense to provide the SIE_KSS feature in the default model. Let's also create a dependency check.

2017-07-14s390x/cpumodel: add esop/esop2 to z12 modelJason J. Herne
Add esop and esop2 features to z12 model where esop2 was originally introduced. Disable esop and esop2 when using compatibility machine v2.9 or earlier. Signed-off-by: Jason J.

Some new guest features have been introduced recently. Let's wire them up in the CPU model. Signed-off-by: Jason J.

2017-07-14s390x/cpumodel: add zpci, aen and ais facilitiesYi Min Zhao
zPCI instructions and facilities are available since IBM zEnterprise EC12. To support z/PCI in QEMU we enable zpci, aen and ais facilities starting with zEC12 GA1. And we always set zpci and aen bits in max cpu model. Later they might be switched off due to applied real cpu model. For ais bit, we only provide it in the full cpu model beginning with zEC12 and defer its enablement in the default cpu model to a later point in time. At the same time, disable them for 2.9 and older machines. Because of introducing AIS facility, we could check if it's enabled to initialize flic->ais_supported with the real value.

2017-07-14s390x/cpumodel: clean up spacing and commentsJason J. Herne
Clean up spacing and add comments to clarify difference between base, full and default models. Not having spacing around the model definitions in gen-features.c is particularly frustrating as the reader tends to misinterpret which model they are looking at or editing. Signed-off-by: Jason J.

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.
