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.

2017-01-31ppc: Rename cpu_version to compat_pvrDavid Gibson
The 'cpu_version' field in PowerPCCPU is badly named. It's named after the 'cpu-version' device tree property where it is advertised, but that meaning may not be obvious in most places it appears. Worse, it doesn't even really correspond to that device tree property. The property contains either the processor's PVR, or, if the CPU is running in a compatibility mode, a special "logical PVR" representing which mode. Rename the cpu_version field, and a number of related variables to compat_pvr to make this clearer.

2017-01-31ppc: Clean up and QOMify hypercall emulationDavid Gibson
The pseries machine type is a bit unusual in that it runs a paravirtualized guest. The guest expects to interact with a hypervisor, and qemu emulates the functions of that hypervisor directly, rather than executing hypervisor code within the emulated system. To implement this in TCG, we need to intercept hypercall instructions and direct them to the machine's hypercall handlers, rather than attempting to perform a privilege change within TCG. This is controlled by a global hook - cpu_ppc_hypercall. This cleanup makes the handling a little cleaner and more extensible than a single global variable. Instead, each CPU to have hypercalls intercepted has a pointer set to a QOM object implementing a new virtual hypervisor interface. A method in that interface is called by TCG when it sees a hypercall instruction. It's possible we may want to add other methods in future.

2017-01-13cputlb: drop flush_global flag from tlb_flushAlex Bennée
We have never has the concept of global TLB entries which would avoid the flush so we never actually use this flag. Drop it and make clear that tlb_flush is the sledge-hammer it has always been.

2017-01-13qom/cpu: move tlb_flush to cpu_common_resetAlex Bennée
It is a common thing amongst the various cpu reset functions want to flush the SoftMMU's TLB entries. This is done either by calling tlb_flush directly or by way of a general memset of the CPU structure (sometimes both). This moves the tlb_flush call to the common reset function and additionally ensures it is only done for the CONFIG_SOFTMMU case and when tcg is enabled. In some target cases we add an empty end_of_reset_fields structure to the target vCPU structure so have a clear end point for any memset which is resetting value in the structure before CPU_COMMON (where the TLB structures are). While this is a nice clean-up in general it is also a precursor for changes coming to cputlb for MTTCG where the clearing of entries can't be done arbitrarily across vCPUs. Currently the cpu_reset function is usually called from the context of another vCPU as the architectural power up sequence is run. By using the cputlb API functions we can ensure the right behaviour in the future.
