2013-02-01net: introduce qemu_get_nic()Jason Wang1-2/+2
To support multiqueue, this patch introduces a helper qemu_get_nic() to get NICState from a NetClientState. The following patches would refactor this helper to support multiqueue. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-01-10Make all static TypeInfos constAndreas Färber1-1/+1
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2012-12-19net: reorganize headersPaolo Bonzini1-1/+1
Move public headers to include/net, and leave private headers in net/. Put the virtio headers in include/net/tap.h, removing the multiple copies that existed. Leave include/net/tap.h as the interface for NICs, and net/tap_int.h as the interface for OS-specific parts of the tap backend. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-08-15pseries: Rework irq assignment to avoid carrying qemu_irqs aroundAlexey Kardashevskiy1-1/+1
Currently, the interfaces in the pseries machine code for assignment and setup of interrupts pass around qemu_irq objects. That was done in an attempt not to be too closely linked to the specific XICS interrupt controller. However interactions with the device tree setup made that attempt rather futile, and XICS is part of the PAPR spec anyway, so this really just meant we had to carry both the qemu_irq pointers and the XICS irq numbers around. This mess will just get worse when we add upcoming PCI MSI support, since that will require tracking a bunch more interrupt. Therefore, this patch reworks the spapr code to just use XICS irq numbers (roughly equivalent to GSIs on x86) and only retrieve the qemu_irq pointers from the XICS code when we need them (a trivial lookup). This is a reworked and generalized version of an earlier spapr_pci specific patch from Alexey Kardashevskiy.

2012-08-01net: Rename VLANClientState to NetClientStateStefan Hajnoczi1-2/+2
The vlan feature is no longer part of net core. Rename VLANClientState to NetClientState because net clients are not explicitly associated with a vlan at all, instead they have a peer net client to which they are connected. This patch is a mechanical search-and-replace except for a few whitespace fixups where changing VLANClientState to NetClientState misaligned whitespace.

2012-06-27pseries: Convert sPAPR TCEs to use generic IOMMU infrastructureDavid Gibson1-30/+33
The pseries platform already contains an IOMMU implementation, since it is essential for the platform's paravirtualized VIO devices. This IOMMU support is currently built into the implementation of the VIO "bus" and the various VIO devices. This patch converts this code to make use of the new common IOMMU infrastructure. We don't yet handle synchronization of map/unmap callbacks vs. invalidations, this will require some complex interaction with the kernel and is not a major concern at this stage.

2012-05-01pseries: Implement automatic PAPR VIO address allocationDavid Gibson1-3/+2
PAPR virtual IO (VIO) devices require a unique, but otherwise arbitrary, "address" used as a token to the hypercalls which manipulate them. Currently the pseries machine code does an ok job of allocating these addresses when the legacy -net nic / -serial and so forth options are used but will fail to allocate them properly when using -device. Specifically, you can use -device if all addresses are explicitly assigned. Without explicit assignment, only one VIO device of each type (network, console, SCSI) will be assigned properly, any further ones will attempt to take the same address leading to a fatal error. This patch fixes the situation by adding a proper address allocator to the VIO "bus" code. This is used both by -device and the legacy options and default devices. Addresses can still be explicitly assigned with -device options if desired. This patch changes the (guest visible) numbering of VIO devices, but since their addresses are discovered using the device tree and already differ from the numbering found on existing PowerVM systems, this does not break compatibility.

2012-04-15pseries: Fix reset of VIO network deviceDavid Gibson1-3/+11
Currently, the PAPR VIO network device does not have a reset handler. This means that after a hard reset, H_REGISTER_LOGICAL_LAN will return an error when the new guest boot attempts to initialize the device. This patch corrects this, adding a suitable reset hook.

2012-04-15pseries: Clean up hcall_dprintf() debugging messagesDavid Gibson1-7/+5
The pseries machine code has a number of debug messages for debugging PAPR hypercalls, dependent on DEBUG_SPAPR_HCALLS. This patch cleans these messages up a bit, by adding __func__ to the hcall_dprintf() macro and simplifying up a number of the individual messages accordingly.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori1-6/+8
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

These are various small stylistic changes which help make things more consistent such that the automated conversion script can be simpler. It's not necessary to agree or disagree with these style changes because all of this code is going to be rewritten by the patch monkey script anyway.

2012-01-03pseries: Remove hcalls callbackDavid Gibson1-11/+6
For forgotten historical reasons, PAPR hypercalls for specific virtual IO devices (oh which there are quite a number) are registered via a callback in the VIOsPAPRDeviceInfo structure. This is kind of ugly, so this patch instead registers hypercalls from device_init() functions for each device type. This works just as well, and is cleaner.

2011-10-06spapr: proper qdevificationPaolo Bonzini1-6/+1
Right now the spapr devices cannot be instantiated with -device, because the IRQs need to be passed to the spapr_*_create functions. Do this instead in the bus's init wrapper. This is particularly important with the conversion from scsi-disk to scsi-{cd,hd} that Markus made. After his patches, if you specify a scsi-cd device attached to an if=none drive, the default VSCSI controller will not be created and, without qdevification, you will not be able to add yours.
