2015-10-14qemu-char: add create to register_char_driverPaolo Bonzini7-100/+133
Having creation as a member of the CharDriver struct removes the need to export functions for qemu-char.c's usage. After the conversion, chardev backends implemented outside qemu-char.c will not need a stub creation function anymore. Ultimately all drivers will be converted. For now, support the case where cd->create == NULL. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-10-13README: fill out some useful quickstart informationDaniel P. Berrange1-2/+106
The README file is usually the first thing consulted when a user or developer obtains a copy of the QEMU source. The current QEMU README is lacking immediately useful information and so not very friendly for first time encounters. It either redirects users to qemu-doc.html (which does not exist until they've actually compiled QEMU), or the website (which assumes the user has convenient internet access at time of reading). This fills out the README file as simple quick-start guide on the topics of building source, submitting patches, licensing and how to contact the QEMU community. It does not intend to be comprehensive, instead referring people to an appropriate web page to obtain more detailed information. The intent is to give users quick guidance to get them going in the right direction. Signed-off-by: Daniel P.

2015-10-12qemu-sockets: fix conversion of ipv4/ipv6 JSON to QemuOptsPaolo Bonzini1-3/+6
The QemuOpts-based code treats "option not set" and "option set to false" the same way for the ipv4 and ipv6 options, because it is meant to handle only the ",ipv4" and ",ipv6" substrings in hand-crafted option parsers. When converting InetSocketAddress to QemuOpts, however, it is necessary to handle all three cases (not set, set to true, set to false). Currently we are not handling all cases correctly. The rules are: * if none or both options are absent, leave things as is * if the single present option is Y, the other should be N. This can be implemented by leaving things as is, or by setting the other option to N as done in this patch. * if the single present option is N, the other should be Y. This is handled by the "else if" branch of this patch. This ensures that the ipv4 option has an effect on Windows, where creating the socket with PF_UNSPEC makes an ipv6 socket. With this patch, ",ipv4" will result in a PF_INET socket instead. Reported-by: Sair, Umair <Umair_Sair@mentor.com> Tested-by: Sair, Umair <Umair_Sair@mentor.com> Reviewed-by: Daniel P.

As the comment in kvm_set_phys_mem() says, KVM works in page size chunks. However it uses hardcoded TARGET_PAGE_SIZE which is 4K on most platforms while actual host may use different page size, for example, PPC64 hosts use 64K system pages. This replaces static TARGET_PAGE_SIZE with run-time calculated qemu_real_host_page_size.

2015-10-12exec.c: Collect AddressSpace related fields into a CPUAddressSpace structPeter Maydell5-31/+48
Gather up all the fields currently in CPUState which deal with the CPU's AddressSpace into a separate CPUAddressSpace struct. This paves the way for allowing the CPU to know about more than one AddressSpace. The rearrangement also allows us to make the MemoryListener a directly embedded object in the CPUAddressSpace (it could not be embedded in CPUState because 'struct MemoryListener' isn't defined for the user-only builds). This allows us to resolve the FIXME in tcg_commit() by going directly from the MemoryListener to the CPUAddressSpace. This patch extracts the actual update of the cached dispatch pointer from cpu_reload_memory_map() (which is renamed accordingly to cpu_reloading_memory_map() as it is only responsible for breaking cpu-exec.c's RCU critical section now). This lets us keep the definition of the CPUAddressSpace struct private to exec.c.

operations The reason for cpu_reload_memory_map()'s RCU operations is not so much because the guest could make the critical section very long, but that it could have a critical section within which it made an arbitrary number of changes to the memory map and thus accumulate an unbounded amount of memory data structures awaiting reclamation.

2015-10-12exec.c: Don't call cpu_reload_memory_map() from cpu_exec_init()Peter Maydell1-1/+0
Currently we call cpu_reload_memory_map() from cpu_exec_init(), but this is not necessary: * KVM doesn't use the data structures maintained by cpu_reload_memory_map() (the TLB and cpu->memory_dispatch) * for TCG, we will call this function via tcg_commit() either as soon as tcg_cpu_address_space_init() registers the listener, or when the first MemoryRegion is added to the AddressSpace if the AS is empty when we register the listener The unnecessary call is awkward for adding support for multiple address spaces per CPU, so drop it.

The raw-posix block driver implements Linux AIO batching so multiple requests can be submitted with a single io_submit(2) system call. Batching is currently only used by virtio-scsi and virtio-blk-data-plane. Enable batching for regular virtio-blk so the number of io_submit(2) system calls is reduced for workloads with queue depth > 1. In 4KB random read performance tests with queue depth 32, the CPU utilization on the host is reduced by 9.4%.
