2013-05-10offline_port: Add support for enabling IP Fragmentation in the O/H port driverRadu Bulie
In order to enable fragmentation on an offline port, a chosen node should be configured in dt for that specific port with two parameters: manip_extra_space and data_align. In addition external buffer pools must be set for the O/H port in the dts file (e.g: fsl,bman-buffer-pools = <&bp8>;). A bool flag is transmited to dpaa_eth_init_port (used further in FMD wrapper) macro whether or not fragmentation was enabled. For the dpaa_eth module this flag must be set to false.(FMD frag support is only available on O/H ports).

2013-05-07Check of qemu emulated PCI controller.Varun Sethi
While implementing direct device assignment for linux guest using identity mapped memory (1:1 guest to host physical mapping), we hit a case where guest end of memory is not a power of two and thus is not completely mapped by the PCI controller inbound window. For a similar condition if the PCI controller supports PCI express capability the fsl_pci driver allows for over commit of inbound memory window. In this patch we introduce a check to see if the PCI controller is a qemu emulated controller. If it's an emulated controller we allow the inbound memory over commit in the fsl_pci driver.

When NCQ is enabled, the SATA controller does not support DMA setup FIS with autoactivate enabled from the device. The SATA host may timeout without finishing the transaction. This will have a minor performance impact as disabling the auto-activate feature requires the device to send a DMA setup as well as a DMA activate FIS to enable reception of the first data FIS. Software will set a flag and check if device enables DMA AA by default, then driver will: 1. Disable the DMA setup auto-activate feature by a set features command. 2. if 1# fail, then disable NCQ by setting the queue depth to one.

2013-05-02kvm/ppc/mpic: remove some obviously unneeded codeScott Wood
Remove some parts of the code that are obviously QEMU or Raven specific before fixing style issues, to reduce the style issues that need to be fixed. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-05-02kvm/ppc/mpic: import hw/openpic.c from QEMUScott Wood
This is QEMU's hw/openpic.c from commit abd8d4a4d6dfea7ddea72f095f993e1de941614e ("Update version for 1.4.0-rc0"), run through Lindent with no other changes to ease merging future changes between Linux and QEMU. Remaining style issues (including those introduced by Lindent) will be fixed in a later patch. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-05-02kvm: add device control APIScott Wood
Currently, devices that are emulated inside KVM are configured in a hardcoded manner based on an assumption that any given architecture only has one way to do it. If there's any need to access device state, it is done through inflexible one-purpose-only IOCTLs (e.g. KVM_GET/SET_LAPIC). Defining new IOCTLs for every little thing is cumbersome and depletes a limited numberspace. This API provides a mechanism to instantiate a device of a certain type, returning an ID that can be used to set/get attributes of the device. Attributes may include configuration parameters (e.g. register base address), device state, operational commands, etc. It is similar to the ONE_REG API, except that it acts on devices rather than vcpus. Both device types and individual attributes can be tested without having to create the device or get/set the attribute, without the need for separately managing enumerated capabilities.

2013-05-02KVM: Move irqfd resample cap handling to generic codeAlexander Graf
Now that we have most irqfd code completely platform agnostic, let's move irqfd's resample capability return to generic code as well. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Michael S. Tsirkin <mst@redhat.com>
2013-05-02KVM: Move irq routing setup to irqchip.cAlexander Graf
Setting up IRQ routes is nothing IOAPIC specific. Extract everything that really is generic code into irqchip.c and only leave the ioapic specific bits to irq_comm.c. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Michael S. Tsirkin <mst@redhat.com> Conflicts: virt/kvm/irq_comm.c Signed-off-by: Stuart Yoder <stuart.yoder@freescale.com>
2013-05-02KVM: Extract generic irqchip logic into irqchip.cAlexander Graf
The current irq_comm.c file contains pieces of code that are generic across different irqchip implementations, as well as code that is fully IOAPIC specific. Split the generic bits out into irqchip.c. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Michael S. Tsirkin <mst@redhat.com> Conflicts: virt/kvm/irq_comm.c Signed-off-by: Stuart Yoder <stuart.yoder@freescale.com>
2013-05-02KVM: Move irq routing to generic codeAlexander Graf
The IRQ routing set ioctl lives in the hacky device assignment code inside of KVM today. This is definitely the wrong place for it. Move it to the much more natural kvm_main.c. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Michael S. Tsirkin <mst@redhat.com>
