* | Fix -machine options accel, kernel_irqchip, kvm_shadow_memMarkus Armbruster2013-07-091-9/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multiple -machine options with the same ID are merged. All but the one without an ID are to be silently ignored. In most places, we query these options with a null ID. This is correct. In some places, we instead query whatever options come first in the list. This is wrong. When the -machine processed first happens to have an ID, options are taken from that ID, and the ones specified without ID are silently ignored. Example: $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=kvm,usb=on QEMU 1.5.50 monitor - type 'help' for more information (qemu) info kvm kvm support: enabled (qemu) info usb (qemu) q $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on QEMU 1.5.50 monitor - type 'help' for more information (qemu) info kvm kvm support: disabled (qemu) info usb (qemu) q $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen QEMU 1.5.50 monitor - type 'help' for more information (qemu) info kvm kvm support: enabled (qemu) info usb USB support not enabled (qemu) q $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error xen be core: can't open xen interface failed to initialize Xen: Operation not permitted Option usb is queried correctly, and the one without an ID wins, regardless of option order. Option accel is queried incorrectly, and which one wins depends on option order and ID. Affected options are accel (and its sugared forms -enable-kvm and -no-kvm), kernel_irqchip, kvm_shadow_mem. Additionally, option kernel_irqchip is normally on by default, except it's off when no -machine options are given. Bug can't bite, because kernel_irqchip is used only when KVM is enabled, KVM is off by default, and enabling always creates -machine options. Downstreams that enable KVM by default do get bitten, though. Use qemu_get_machine_opts() to fix these bugs.

| * pci: Add root bus parameter to pci_nic_init()David Gibson2013-07-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | At present, pci_nic_init() and pci_nic_init_nofail() assume that they will only create a NIC under the primary PCI root. As we add support for multiple PCI roots, that may no longer be the case. This patch adds a root bus parameter to pci_nic_init() (and updates callers accordingly) to allow the machine init code using it to specify the right PCI root for NICs created by old-style -net nic parameters. NICs created new-style, with -device can of course be put anywhere. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

* kvm/openpic: in-kernel mpic supportScott Wood2013-07-011-5/+74
| | | | | | | | | | | | | | | | | | | | | | | Enables support for the in-kernel MPIC that thas been merged into the KVM next branch. This includes irqfd/KVM_IRQ_LINE support from Alex Graf (along with some other improvements). Note from Alex regarding kvm_irqchip_create(): On x86, one would call kvm_irqchip_create() to initialize an in-kernel interrupt controller. That function then goes ahead and initializes global capability variables as well as the default irq routing table. On ppc, we can't call kvm_irqchip_create() because we can have different types of interrupt controllers. So we want to do all the things that function would do for us in the in-kernel device init handler.

* | Adding BAR0 for e500 PCI controllerBharat Bhushan2012-12-141-9/+46

The type-1 configuration header have a BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pci address space to CCSR address space. This can used for 2 purposes: 1) for MSI interrupt generation 2) Allow CCSR registers access when configured as PCI endpoint, which I am not sure is a use case with QEMU-KVM guest. What I observed is that when guest read the size of BAR0 of host controller configuration header (TYPE1 header) then it always reads it as 0. When looking into the QEMU hw/ppce500_pci.c, I do not find the PCI controller device registering BAR0. I do not find any other controller also doing so may they do not use BAR0. There are two issues when BAR0 is not there (which I can think of): 1) There should be BAR0 emulated for PCI Root complex (TYPE1 header) and when reading the size of BAR0, it should give size as per real h/w. 2) Do we need this BAR0 inbound address translation? When BAR0 is of non-zero size then it will be configured for PCI address space to local address(CCSR) space translation on inbound access. The primary use case is for MSI interrupt generation. The device is configured with an address offsets in PCI address space, which will be translated to MSI interrupt generation MPIC registers. Currently I do not understand the MSI interrupt generation mechanism in QEMU and also IIRC we do not use QEMU MSI interrupt mechanism on e500 guest machines. But this BAR0 will be used when using MSI on e500. I can see one more issue, There are ATMUs emulated in hw/ppce500_pci.c, but i do not see these being used for address translation. So far that works because pci address space and local address space are 1:1 mapped. BAR0 inbound translation + ATMU translation will complete the address translation of inbound traffic.

|/ | | | | | | | | | | | All devices are also placed under CCSR memory region. The CCSR memory region is exported to pci device. The MSI interrupt generation is the main reason to export the CCSR region to PCI device. This put the requirement to move mpic under CCSR region, but logically all devices should be under CCSR.

* PPC: e500: Only expose even TLB sizes in initial TLBAlexander Graf2012-10-051-0/+4
| | | | | | | | | | | | | | | | When booting our e500 machine, we automatically generate a big TLB entry in TLB1 that covers all of the code we need to run in there until the guest can handle its TLB on its own. However, e500v2 can only handle MAS1.0 sizes. However, we keep our TLB information in MAS2.0 layout, which means we have twice as many TLB sizes to choose from. That also means we can run into a situation where we try to add a TLB size that could not fit into the MAS1.0 size bits. Fix it by making sure we always have the lower bit set to 0. That way we are always guaranteed to have MAS1.0 compatible TLB size information. Signed-off-by: Alexander Graf <agraf@suse.de>
* PPC: e500: calculate initrd_base like dt_baseScott Wood2012-10-051-1/+2
| | | | | | | | While investigating dtb pad issues, I noticed that initrd_base wasn't taking loadaddr into account the way dt_base was. This seems wrong. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
* PPC: e500: increase DTC_LOAD_PADScott Wood2012-10-051-1/+1
| | | | | | | | | | | | | | An allowance of 5 MiB for BSS is not enough for Linux kernels with certain debug options enabled (not sure exactly which one caused it, but I'd guess lockdep). The kernel I ran into this with had a BSS of around 6.4 MB. Unfortunately, uImage does not give us enough information to determine the actual BSS size. Increase the allowance to 18 MiB to give us plenty of room. Eventually this should be more intelligent, possibly packing initrd+dtb at the end of guest RAM.
