2017-01-31target/ppc/cpu-models: Fix/remove bad CPU aliasesThomas Huth
There is no CPU model called "7447_v1.2" in our list, so the "7447" alias should point to "7447_v1.1" instead. Let's also remove the "codename" aliases that point to non-implemented CPU models - they are really of no use here.

2017-01-31spapr: clock should count only if vm is runningLaurent Vivier
This is a port to ppc of the i386 commit: 00f4d64 kvmclock: clock should count only if vm is running We remove timebase_post_load function, and use the VM state change handler to save and restore the guest_timebase (on stop and continue). We keep timebase_pre_save to reduce the clock difference on migration like in: 6053a86 kvmclock: reduce kvmclock difference on migration Time base offset has originally been introduced by commit 98a8b52 spapr: Add support for time base offset migration So while VM is paused, the time is stopped. This allows to have the same result with date (based on Time Base Register) and hwclock (based on "get-time-of-day" RTAS call). Moreover in TCG mode, the Time Base is always paused, so this patch also adjust the behavior between TCG and KVM. VM state field "time_of_the_day_ns" is now useless but we keep it to be able to migrate to older version of the machine. As vmstate_ppc_timebase structure (with timebase_pre_save() and timebase_post_load() functions) was only used by vmstate_spapr, we register the VM state change handler only in ppc_spapr_init().

2017-01-31ppc: Add ppc_set_compat_all()David Gibson
Once a compatiblity mode is negotiated with the guest, h_client_architecture_support() uses run_on_cpu() to update each CPU to the new mode. We're going to want this logic somewhere else shortly, so make a helper function to do this global update. We put it in target-ppc/compat.c - it makes as much sense at the CPU level as it does at the machine level. We also move the cpu_synchronize_state() into ppc_set_compat(), since it doesn't really make any sense to call that without synchronizing state.

2017-01-31ppc: Validate compatibility modes when settingDavid Gibson
Current ppc_set_compat() will attempt to set any compatiblity mode specified, regardless of whether it's available on the CPU. The caller is expected to make sure it is setting a possible mode, which is awkwward because most of the information to make that decision is at the CPU level. This begins to clean this up by introducing a ppc_check_compat() function which will determine if a given compatiblity mode is supported on a CPU (and also whether it lies within specified minimum and maximum compat levels, which will be useful later). It also contains an assertion that the CPU has a "virtual hypervisor"[1], that is, that the guest isn't permitted to execute hypervisor privilege code. Without that, the guest would own the PCR and so could override any mode set here. Only machine types which use a virtual hypervisor (i.e. 'pseries') should use ppc_check_compat(). ppc_set_compat() is modified to validate the compatibility mode it is given and fail if it's not available on this CPU. [1] Or user-only mode, which also obviously doesn't allow access to the hypervisor privileged PCR. We don't use that now, but could in future.

2017-01-31ppc: Rewrite ppc_get_compat_smt_threads()David Gibson
To continue consolidation of compatibility mode information, this rewrites the ppc_get_compat_smt_threads() function using the table of compatiblity modes in target-ppc/compat.c. It's not a direct replacement, the new ppc_compat_max_threads() function has simpler semantics - it just returns the number of threads the cpu model has, taking into account any compatiblity mode it is in. This no longer takes into account kvmppc_smt_threads() as the previous version did. That check wasn't useful because we check in ppc_cpu_realizefn() that CPUs aren't instantiated with more threads than kvm allows (or if we didn't things will already be broken and this won't make it any worse).

2017-01-31ppc: Rewrite ppc_set_compat()David Gibson
This rewrites the ppc_set_compat() function so that instead of open coding the various compatibility modes, it reads the relevant data from a table. This is a first step in consolidating the information on compatibility modes scattered across the code into a single place. It also makes one change to the logic. The old code masked the bits to be set in the PCR (Processor Compatibility Register) by which bits are valid on the host CPU. This made no sense, since it was done regardless of whether our guest CPU was the same as the host CPU or not. Furthermore, the actual PCR bits are only relevant for TCG[1] - KVM instead uses the compatibility mode we tell it in kvmppc_set_compat(). When using TCG host cpu information usually isn't even present. While we're at it, we put the new implementation in a new file to make the enormous translate_init.c a little smaller. [1] Actually it doesn't even do anything in TCG, but it will if / when we get to implementing compatibility mode logic at that level.
