2014-03-10target-arm: Implement WFE as a yield operationPeter Maydell
Implement WFE to yield our timeslice to the next CPU. This avoids slowdowns in multicore configurations caused by one core busy-waiting on a spinlock which can't possibly be unlocked until the other core has an opportunity to run. This speeds up my test case A15 dual-core boot by a factor of three (though it is still four or five times slower than a single-core boot).

2014-03-09memory_region_present: return false if address is not found in child ↵Igor Mammedov
MemoryRegion Windows XP shows COM2 port as non functional in "Device Manager" although no COM2 port backing device is present in QEMU. This regression is really due to 3bb28b7208b349e7a1b326e3c6ef9efac1d462bf? memory: Provide separate handling of unassigned io ports accesses That is caused by the fact that QEMU reports to OSPM that device is present by setting 5th bit in PII4XPM.pci_conf[0x67] register when COM2 doesn't exist. It happens due to memory_region_present(io_as, 0x2f8) returning false positive since 0x2f8 address eventually translates into catchall io_as address space. Fix memory_region_present(parent, addr) by returning true only if addr maps into a MemoryRegion within parent (excluding parent itself), to match its doc comment. While at it fix copy/paste error in memory_region_present() doc comment. Note: this is a temporary hack: we really need better handling for unassigned regions, we should avoid fallback regions since they are bad for performance (breaking radix tree assumption that the data structure is sparsely populated); for memory we need to fix this to implement PCI master abort properly, anyway.

2014-02-04exec: fix ram_list dirty map optimizationAlexey Kardashevskiy
The ae2810c4bb3b383176e8e1b33931b16c01483aab patch introduced optimization for ram_list.dirty_memory update. However it can only work correctly if hpratio is 1 as the @bitmap parameter stores 1 bits per system page size (may vary, 4K or 64K on PPC64) and ram_list.dirty_memory stores 1 bit per TARGET_PAGE_SIZE (which is hardcoded to 4K). This fixes hpratio!=1 case to fall back to the slow path. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Juan Quintela <quintela@redhat.com>

2014-02-01qemu 1.7.0 does not build on NetBSDMartin Husemann
Do not rely on int8_t (and friends) not being preprocessor symbols (or symbols expanding to themselves). On NetBSD (for example) the glue(u, SDATA_TYPE) results in u__int8_t, which is undefined. There is no way to stop cpp expanding inner macros, so just add the few lines explicitly and get rid of the magic.

2014-01-17kvm: initialize qemu_host_page_sizeAlexey Kardashevskiy
There is a HOST_PAGE_ALIGN macro which makes sense for KVM accelerator but it uses qemu_host_page_size/qemu_host_page_mask which initialized for TCG only. This moves qemu_host_page_size/qemu_host_page_mask initialization from TCG's page_init() and adds a call for it from kvm_init().
