Beside of switching to generic infrastructure it solves several issues. * ppc_cpu_class_by_name() is used to deal with lower/upper case and alias translations into actual cpu type, which fixes '-M powernv -cpu power8' and '-M powernv -cpu power9_v1.0' usecases which error out with: 'invalid CPU model 'FOO' for powernv machine' * allows to switch to lower-case typenames in pnv chip/core name (by convention typnames should be lower-case) * replace aliased names /power8, power9, .../ with exact cpu model names (i.e. typenames should be stable but aliases might decide to point to other cpu model withi family or changed by kvm).

2017-10-17ppc: move '-cpu foo,compat=xxx' parsing into ppc_cpu_parse_featurestr()Igor Mammedov1-1/+0
there is a dedicated callback CPUClass::parse_features which purpose is to convert -cpu features into a set of global properties AND deal with compat/legacy features that couldn't be directly translated into CPU's properties. Create ppc variant of it (ppc_cpu_parse_featurestr) and move 'compat=val' handling from spapr_cpu_core.c into it. That removes a dependency of board/core code on cpu_model parsing and would let to reuse common -cpu parsing introduced by 6063d4c0 Set "max-cpu-compat" property only if it exists, in practice it should limit 'compat' hack to spapr machine and allow to avoid including machine/spapr headers in target/ppc/cpu.c Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2017-10-17qom: add helper macro DEFINE_TYPES()Igor Mammedov1-0/+36
DEFINE_TYPES() will help to simplify following routine patterns: static void foo_register_types(void) { type_register_static(&foo1_type_info); type_register_static(&foo2_type_info); ... } type_init(foo_register_types) or static void foo_register_types(void) { int i; for (i = 0; i < ARRAY_SIZE(type_infos); i++) { type_register_static(&type_infos[i]); } } type_init(foo_register_types) with a single line DEFINE_TYPES(type_infos) where types have static definition which could be consolidated in a single array of TypeInfo structures. It saves us ~6-10LOC per use case and would help to replace imperative foo_register_types() there with declarative style of type registration.

2017-10-16io: get rid of bounce buffering in websock write pathDaniel P. Berrange1-1/+0
Currently most outbound I/O on the websock channel gets copied into the rawoutput buffer, and then immediately copied again into the encoutput buffer, with a header prepended. Now that qio_channel_websock_encode accepts a struct iovec, we can trivially remove this bounce buffering and write directly to encoutput. In doing so, we also now correctly validate the encoutput size against the QIO_CHANNEL_WEBSOCK_MAX_BUFFER limit. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2017-10-16io: simplify websocket ping reply handlingDaniel P. Berrange1-1/+1
We must ensure we don't get flooded with ping replies if the outbound channel is slow. Currently we do this by keeping the ping reply in a separate temporary buffer and only writing it if the encoutput buffer is completely empty. This is overly pessimistic, as it is reasonable to add a ping reply to the encoutput buffer even if it has previous data in it, as long as that previous data doesn't include a ping reply. To track this better, put the ping reply directly into the encoutput buffer, and then record the size of encoutput at this time in pong_remain. As we write encoutput to the underlying channel, we can decrement the pong_remain counter. Once it hits zero, we can accept further ping replies for transmission.

2017-10-13block: add bdrv_co_drain_end callbackManos Pitsidianakis1-2/+9
BlockDriverState has a bdrv_co_drain() callback but no equivalent for the end of the drain. The throttle driver (block/throttle.c) needs a way to mark the end of the drain in order to toggle io_limits_disabled correctly, thus bdrv_co_drain_end is needed.

2017-10-10tcg: consolidate TB lookups in tb_lookup__cpu_stateEmilio G. Cota1-0/+49
This avoids duplicating code. cpu_exec_step will also use the new common function once we integrate parallel_cpus into tb->cflags. Note that in this commit we also fix a race, described by Richard Henderson during review. Think of this scenario with threads A and B: (A) Lookup succeeds for TB in hash without tb_lock (B) Sets the TB's tb->invalid flag (B) Removes the TB from tb_htable (B) Clears all CPU's tb_jmp_cache (A) Store TB into local tb_jmp_cache Given that order of events, (A) will keep executing that invalid TB until another flush of its tb_jmp_cache happens, which in theory might never happen. We can fix this by checking the tb->invalid flag every time we look up a TB from tb_jmp_cache, so that in the above scenario, next time we try to find that TB in tb_jmp_cache, we won't, and will therefore be forced to look it up in tb_htable.

2017-10-10cputlb: bring back tlb_flush_count under !TLB_DEBUGEmilio G. Cota2-2/+2
Commit f0aff0f124 ("cputlb: add assert_cpu_is_self checks") buried the increment of tlb_flush_count under TLB_DEBUG. This results in "info jit" always (mis)reporting 0 TLB flushes when !TLB_DEBUG. Besides, under MTTCG tlb_flush_count is updated by several threads, so in order not to lose counts we'd either have to use atomic ops or distribute the counter, which is more scalable. This patch does the latter by embedding tlb_flush_count in CPUArchState. The global count is then easily obtained by iterating over the CPU list. Note that this change also requires updating the accessors to tlb_flush_count to use atomic_read/set whenever there may be conflicting accesses (as defined in C11) to it.
