2013-05-30qapi: pad GenericList value fields to 64 bitsMichael Roth
With the introduction of native list types, we now have types such as int64List where the 'value' field is not a pointer, but the actual 64-bit value. On 32-bit architectures, this can lead to situations where 'next' field offset in GenericList does not correspond to the 'next' field in the types that we cast to GenericList when using the visit_next_list() interface, causing issues when we attempt to traverse linked list structures of these types. To fix this, pad the 'value' field of GenericList and other schema-defined/native *List types out to 64-bits. This is less memory-efficient for 32-bit architectures, but allows us to continue to rely on list-handling interfaces that target GenericList to simply visitor implementations. In the future we can improve efficiency by defaulting to using native C array backends to handle list of non-pointer types, which would be more memory efficient in itself and allow us to roll back this change.

2013-05-29memory: add address_space_translatePaolo Bonzini
Using phys_page_find to translate an AddressSpace to a MemoryRegionSection is unwieldy. It requires to pass the page index rather than the address, and later memory_region_section_addr has to be called. Replace memory_region_section_addr with a function that does all of it: call phys_page_find, compute the offset within the region, and check how big the current mapping is. This way, a large flat region can be written with a single lookup rather than a page at a time. address_space_translate will also provide a single point where IOMMU forwarding is implemented.

2013-05-24memory: limit sections in the radix tree to the actual address space sizeAvi Kivity
The radix tree is statically sized to fit TARGET_PHYS_ADDR_SPACE_BITS. If a larger memory region is registered, it will overflow. Fix by limiting any section in the radix tree to the supported size. This problem was not observed earlier since artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes. An IOMMU however cannot be eliminated by the memory core, and may have an artificial size.

2013-05-24memory: Rename readable flag to romd_modeJan Kiszka
"Readable" is a very unfortunate name for this flag because even a rom_device region will always be readable from the guest POV. What differs is the mapping, just like the comments had to explain already. Also, readable could currently be understood as being a generic region flag, but it only applies to rom_device regions. So rename the flag and the function to modify it after the original term "ROMD" which could also be interpreted as "ROM direct", i.e. ROM mode with direct access. In any case, the scope of the flag is clearer now.

2013-05-24coroutine: stop using AioContext in CoQueueStefan Hajnoczi
qemu_co_queue_next(&queue) arranges that the next queued coroutine is run at a later point in time. This deferred restart is useful because the caller may not want to transfer control yet. This behavior was implemented using QEMUBH in the past, which meant that CoQueue (and hence CoMutex and CoRwlock) had a dependency on the AioContext event loop. This hidden dependency causes trouble when we move to a world with multiple event loops - now qemu_co_queue_next() needs to know which event loop to schedule the QEMUBH in. After pondering how to stash AioContext I realized the best solution is to not use AioContext at all. This patch implements the deferred restart behavior purely in terms of coroutines and no longer uses QEMUBH. Here is how it works: Each Coroutine has a wakeup queue that starts out empty. When qemu_co_queue_next() is called, the next coroutine is added to our wakeup queue. The wakeup queue is processed when we yield or terminate. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-05-13qom: aggressively optimize qom castingAnthony Liguori
This patch adds a small typename cache to ObjectClass. This allows caching positive casts within each ObjectClass. Benchmarking a PPC workload provided by Aurelien, this patch eliminates every single g_hash_table_lookup() happening during the benchmark (which was about 2 million per-second). With this patch applied, I get exactly the same performance (within the margin of error) as with --disable-qom-cast-debug. N.B. it's safe to cache typenames only from the _assert() macros because they are always called with string literals. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
