2011-08-26vhost-net: cleanup host notifiers at last stepMichael S. Tsirkin3-22/+70
When the vhost notifier is disabled, the userspace handler runs immediately: virtio_pci_set_host_notifier_internal might call virtio_queue_notify_vq. Since the VQ state and the tap backend state aren't recovered yet, this causes "Guest moved used index from XXX to YYY" assertions. The solution is to split out host notifier handling from vhost VQ setup and disable notifiers as our last step when we stop vhost-net. For symmetry enable them first thing on start.

2011-08-24pci: Error on PCI capability collisionsJan Kiszka1-0/+38
Nothing good can happen when we overlap capabilities. This may happen when plugging in assigned devices or when devices models contain bugs. Detect the overlap and report it.

2011-08-24pcie/slot: fix hotplug eventIsaku Yamahata1-0/+12
When slot status register is cleared, PCIDevice::exp.hpev_notify needs to be cleared. Otherwise, PCIDevice::exp.hpev_notify is never set to false resulting in no more hot plug event once it's raised.

2011-08-23PPC: E500: Set ESR valuesAlexander Graf1-0/+6
When an exception occurs on BookE, we need to set ESR bits to expose to the guest information on what exactly happened. Add the obvious ones.

2011-08-23PPC: E500: Inject SPE exception on invalid SPE accessAlexander Graf1-39/+39
When accessing an SPE instruction despite it being not available, throw an SPE exception instead of an APU exception. That way the guest knows what's going on and actually uses SPE.

2011-08-23hw/omap_gpmc: Don't try to map CS0 twice on resetPeter Maydell1-1/+0
Remove a spurious second map of the OMAP GPMC CS0 region on reset. This fixes an assertion failure when we try to add the region to its container when it was already added. (The old code did not complain about mismatched map/unmap calls, but the new MemoryRegion implementation does.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Edgar E.

2011-08-22Replace qemu_system_cond with VCPU stop mechanismJan Kiszka1-14/+6
We can express the VCPU thread wakeup with the stop mechanism, saving both qemu_system_ready and the qemu_system_cond. For KVM threads, we can just enter the main loop as long as the thread is stopped. The central TCG thread is better held back before the loop as there can be side effects of the services called even when all CPUs are stopped. Creating VCPUs in stopped state will also be required for proper CPU hotplugging support. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-08-22vga: Use linear mapping + dirty logging in chain 4 memory access modeJan Kiszka2-1/+52
Most VGA memory access modes require MMIO handling as they demand weird logic to get a byte from or into the video RAM. However, there is one exception: chain 4 mode with all memory planes enabled for writing. This mode actually allows lineary mapping, which can then be combined with dirty logging to accelerate KVM. This patch accelerates specifically VBE accesses like they are used by grub in graphical mode. Not only the standard VGA adapter benefits from this, also vmware and spice in VGA mode.

2011-08-22target-i386: Remove unused polarity arguments from APIC APIJan Kiszka4-21/+13

2011-08-22Do not kick vcpus in TCG modeJan Kiszka1-1/+1
In TCG mode, iothread and vcpus run in lock-step. So it's pointless to send a signal from qemu_cpu_kick to the vcpu thread - if we got here, the receiver already left the vcpu loop. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-08-22Poll main loop after I/O events were receivedJan Kiszka2-5/+9
Polling until select returns empty fdsets helps to reduce the switches between iothread and vcpus.

2011-08-22Do not drop global mutex for polled main loop runsJan Kiszka1-2/+8
If we call select without a timeout, it's more efficient to keep the global mutex locked as we may otherwise just play ping pong with a vcpu thread contending for it.

2011-08-22memory: Fix old_portio vs non-zero offsetRichard Henderson1-2/+2
The legacy functions that we're wrapping expect that offset to be included in the register. Indeed, they generally expect the absolute address and then mask off the "high" bits.

2011-08-22memory: temporarily suppress the subregion collision warningAnthony Liguori1-0/+2
After 312b4234, the APIC and PCI devices are colliding with each other. This is harmless in practice because the APIC accesses are special cased and never make there way onto the bus. Avi is working on a proper fix, but until that's ready, avoid printing the warning. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-08-22440fx: fix PAM, PCI holesAvi Kivity4-46/+115
The current implementation of PAM and the PCI holes is broken in several ways: - PCI BARs are not restricted to the PCI hole (a BAR may hide memory) - PCI devices do not respect PAM (if a PCI device maps a region while PAM maps the region to RAM, the request will be honored) This patch fixes things by introducing a pci address space, and using memory region aliases to represent PAM regions, SMRAM, and PCI holes. The memory hierarchy looks something like system_memory | +--- low memory alias (0-0xe0000000) | | | +-- ram@0 | +--- high memory alias (0x100000000-EOM) | | | +-- ram@0xe0000000 | +--- pci hole alias (end of low memory-0x100000000) | | | +-- pci@end-of-low-memory | | +--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1) | | | +-- pci@0xc4000 etc | +--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1) | +-- pci@0xa0000 etc ram (simple ram region) pci | +--- BARn | +--- VGA 0xa0000-0xbffff | +--- ROMs Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
