| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

| * kvm: Rework VCPU synchronizationJan Kiszka2009-06-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During startup and after reset we have to synchronize user space to the in-kernel KVM state. Namely, we need to transfer the VCPU registers when they change due to VCPU as well as APIC reset. This patch refactors the required hooks so that kvm_init_vcpu registers its own per-VCPU reset handler and adds a cpu_synchronize_state to the APIC reset. That way we no longer depend on the new reset order (and can drop this disliked interface again) and we can even drop a KVM hook in main().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a backport of the guest debugging support for the KVM accelerator that is now part of the KVM tree. It implements the reworked KVM kernel API for guest debugging (KVM_CAP_SET_GUEST_DEBUG) which is not yet part of any mainline kernel but will probably be 2.6.30 stuff. So far supported is x86, but PPC is expected to catch up soon. Core features are: - unlimited soft-breakpoints via code patching - hardware-assisted x86 breakpoints and watchpoints Changes in this version: - use generic hook cpu_synchronize_state to transfer registers between user space and kvm - push kvm_sw_breakpoints into KVMState Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6825 c046a42c-6fe2-441c-8c8c-71466251a162

| * KVM: Coalesced MMIO supportaliguori2008-12-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MMIO exits are more expensive in KVM or Xen than in QEMU because they involve, at least, privilege transitions. However, MMIO write operations can be effectively batched if those writes do not have side effects. Good examples of this include VGA pixel operations when in a planar mode. As it turns out, we can get a nice boost in other areas too. Laurent mentioned a 9.7% performance boost in iperf with the coalesced MMIO changes for the e1000 when he originally posted this work for KVM.

| * Add virtio-balloon supportaliguori2008-12-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a VirtIO based balloon driver. It uses madvise() to actually balloon the memory when possible. Until 2.6.27, KVM forced memory pinning so we must disable ballooning unless the kernel actually supports it when using KVM. It's always safe when using TCG.

| * kvm: Introduce kvm logging interface (Glauber Costa)aliguori2008-11-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce functions to control logging of memory regions. We select regions based on its start address, a guest_physical_addr (target_phys_addr_t, in qemu nomenclature). The main user of this interface right now is VGA optimization (a way of reducing the number of mmio exits).
