2013-09-03cpu: Replace qemu_for_each_cpu()Andreas Färber1-11/+9
It was introduced to loop over CPUs from target-independent code, but since commit 182735efaf956ccab50b6d74a4fed163e0f35660 target-independent CPUState is used. A loop can be considered more efficient than function calls in a loop, and CPU_FOREACH() hides implementation details just as well, so use that instead.

2013-09-02Revert "usb-hub: report status changes only once"Gerd Hoffmann1-5/+1
This reverts commit a309ee6e0a256f690760abfba44fceaa52a7c2f3. This isn't in line with the usb specification and adds regressions, win7 fails to drive the usb hub for example. Was added because it "solved" the issue of hubs interacting badly with the xhci host controller. Now with the root cause being fixed in xhci (commit <FIXME>) we can revert this one.

2013-09-02spapr-pci: rework MSI/MSIXAlexey Kardashevskiy2-38/+52
On the sPAPR platform a guest allocates MSI/MSIX vectors via RTAS hypercalls which return global IRQ numbers to a guest so it only operates with those and never touches MSIMessage. Therefore MSIMessage handling is completely hidden in QEMU. Previously every sPAPR PCI host bridge implemented its own MSI window to catch msi_notify()/msix_notify() calls from QEMU devices (virtio-pci or vfio) and route them to the guest via qemu_pulse_irq(). MSIMessage used to be encoded as: .addr - address within the PHB MSI window; .data - the device index on PHB plus vector number. The MSI MR write function translated this MSIMessage to a global IRQ number and called qemu_pulse_irq(). However the total number of IRQs is not really big (at the moment it is 1024 IRQs starting from 4096) and even 16bit data field of MSIMessage seems to be enough to store an IRQ number there. This simplifies MSI handling in sPAPR PHB. Specifically, this does: 1. remove a MSI window from a PHB; 2. add a single memory region for all MSIs to sPAPREnvironment and spapr_pci_msi_init() to initialize it; 3. encode MSIMessage as: * .addr - a fixed address of SPAPR_PCI_MSI_WINDOW==0x40000000000ULL; * .data as an IRQ number. 4. change IRQ allocator to align first IRQ number in a block for MSI. MSI uses lower bits to specify the vector number so the first IRQ has to be aligned. MSIX does not need any special allocator though.

2013-09-02spapr-pci: fix config space access to support bridgesAlexey Kardashevskiy1-10/+2
spapr-pci config space accessors use find_dev() to find a PCI device. However find_dev() only searched on a primary bus and did not do recursive search through secondary buses so config space access was not possible for devices other that on a primary bus. This fixed find_dev() by using the PCI API pci_find_device() function. This effectively enabled pci bridges on spapr. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Acked-by: Michael S.

2013-09-02pseries: Fix stalls on hypervisor virtual consoleAnton Blanchard1-0/+2
A number of users are reporting stalls when using the pseries hypervisor virtual console. A simple test case is to paste 15 or 17 characters at a time into the console. Pasting 15 characters at a time works fine but pasting 17 characters hangs for a random amount of time. Other activity (network, qemu monitor etc) unblocks it. If qemu-char tries to send more than 16 characters at once, vty_can_receive returns false. At this point we have to wait for the guest to consume that output. Everything is good so far. The problem occurs when the the guest does consume the output. We need to signal back to the qemu-char layer that we are ready for more input. Without this we block until something else kicks us (eg network activity). Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-09-02PPC: E500: Generate device tree on resetAlexander Graf1-9/+43
Today we generate the device tree once on machine initialization and then store the finalized blob in memory to reload it on reset. This is bad for 2 reasons. First we potentially waste a bunch of RAM for no good reason, as we have all information required to regenerate the device tree available anyways. The second reason is even more important. On machine init when we generate the device tree for the first time, we don't have all of the devices fully initialized yet. But the device tree needs to potentially walk devices to put information about them into the device tree. Move the generation into a reset function. That way we just generate it new every time we reset, solving both of the above issues. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-09-01pc: reduce duplication, fix PIIX descriptionsMichael S. Tsirkin2-63/+48
We have a lot of code duplication between machine types, this increases with each new machine type and each new field. This has already introduced a minor bug: description for pc-1.3 says "Standard PC" while description for pc-1.4 is "Standard PC (i440FX + PIIX, 1996)" which makes you think 1.3 is somehow more standard, or newer, while in fact it's a revision of the same PC. This patch addresses this issue by using macros, along the lines used by PC_COMPAT_X_X - only for non-property options. The approach can extend to non-PC machine types.
