* s390x: protvirt: Move diag 308 data over SIDAJanosch Frank2020-04-291-5/+20
| | | | | | | | | | | | | For protected guests the IPIB is written/read to/from the SIDA, so we need those accesses to go through s390_cpu_pv_mem_read/write().

* s390x: protvirt: Support unpack facilityJanosch Frank2020-04-291-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | The unpack facility provides the means to setup a protected guest. A protected guest cannot be introspected by the hypervisor or any user/administrator of the machine it is running on. Protected guests are encrypted at rest and need a special boot mechanism via diag308 subcode 8 and 10. Code 8 sets the PV specific IPLB which is retained separately from those set via code 5. Code 10 is used to unpack the VM into protected memory, verify its integrity and start it.

* s390x: Return specification exception for unimplemented diag 308 subcodesJanosch Frank2019-01-181-1/+1
| | | | | | | | | | | | | | | | | | The architecture specifies specification exceptions for all unavailable subcodes. The presence of subcodes is indicated by checking some query subcode. For example 6 will indicate that 3-6 are available. So future systems might call new subcodes to check for new features. This should not trigger a hw error, instead we return the architectured specification exception.

* s390x: refactor reset/reipl handlingDavid Hildenbrand2018-05-141-57/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | Calling pause_all_vcpus()/resume_all_vcpus() from a VCPU thread might not be the best idea. As pause_all_vcpus() temporarily drops the qemu mutex, two parallel calls to pause_all_vcpus() can be active at a time, resulting in a deadlock. (either by two VCPUs or by the main thread and a VCPU) Let's handle it via the main loop instead, as suggested by Paolo. If we would have two parallel reset requests by two different VCPUs at the same time, the last one would win. We use the existing ipl device to handle it. The nice side effect is that we can get rid of reipl_requested. This change implies that all reset handling now goes via the common path, so "no-reboot" handling is now active for all kinds of reboots. Let's execute any CPU initialization code on the target CPU using run_on_cpu.

| | | | | | | | | | | | | | | | | | | | | | | | cpu.h should only contain what really has to be accessed outside of target/s390x/. Add internal.h which can only be used inside target/s390x/. Move everything that isn't fast enough to run away and restructure it right away. We'll move all kvm_* stuff later. Minor style fixes to avoid checkpatch warning to: - struct Lowcore: "{" goes into same line as typedef - struct LowCore: add spaces around "-" in array length calculations - time2tod() and tod2time(): move "{" to separate line - get_per_atmid(): add space between ")" and "?". Move cases by one char. - get_per_atmid(): drop extra paremthesis around (1 << 6) Change license of new file to GPL2+ and keep copyright notice.
