2016-03-24spice: Disallow use of gl + TCP portChristophe Fergeau1-0/+5
Currently, virgl support has to go through a local unix socket, trying to connect to a VM using -spice gl through spice://localhost:5900 will only result in a black screen. This commit errors out when the user tries to start a VM with both GL support and a port/tls-port set. This would fit better in spice-server, but currently QEMU does not call into spice-server when parsing 'gl' on its command line, so we have to do this check in QEMU instead.

2016-03-24hw/net/spapr_llan: Fix receive buffer handling for better performanceThomas Huth1-2/+216
tl;dr: This patch introduces an alternate way of handling the receive buffers of the spapr-vlan device, resulting in much better receive performance for the guest. Full story: One of our testers recently discovered that the performance of the spapr-vlan device is very poor compared to other NICs, and that a simple "ping -i 0.2 -s 65507 someip" in the guest can result in more than 50% lost ping packets (especially with older guest kernels < 3.17). After doing some analysis, it was clear that there is a problem with the way we handle the receive buffers in spapr_llan.c: The ibmveth driver of the guest Linux kernel tries to add a lot of buffers into several buffer pools (with 512, 2048 and 65536 byte sizes by default, but it can be changed via the entries in the /sys/devices/vio/1000/pool* directories of the guest). However, the spapr-vlan device of QEMU only tries to squeeze all receive buffer descriptors into one single page which has been supplied by the guest during the H_REGISTER_LOGICAL_LAN call, without taking care of different buffer sizes. This has two bad effects: First, only a very limited number of buffer descriptors is accepted at all. Second, we also hand 64k buffers to the guest even if the 2k buffers would fit better - and this results in dropped packets in the IP layer of the guest since too much skbuf memory is used. Though it seems at a first glance like PAPR says that we should store the receive buffer descriptors in the page that is supplied during the H_REGISTER_LOGICAL_LAN call, chapter 16.4.1.2 in the LoPAPR spec declares that "the contents of these descriptors are architecturally opaque, none of these descriptors are manipulated by code above the architected interfaces". That means we don't have to store the RX buffer descriptors in this page, but can also manage the receive buffers at the hypervisor level only. This is now what we are doing here: Introducing proper RX buffer pools which are also sorted by size of the buffers, so we can hand out a buffer with the best fitting size when a packet has been received. To avoid problems with migration from/to older version of QEMU, the old behavior is also retained and enabled by default. The new buffer management has to be enabled via a new "use-rx-buffer-pools" property. Now with the new buffer pool management enabled, the problem with "ping -s 65507" is fixed for me, and the throughput of a simple test with wget increases from creeping 3MB/s up to 20MB/s!

2016-03-24spapr/target-ppc/kvm: Only add hcall-instructions if KVM supports itAlexey Kardashevskiy2-5/+6
ePAPR defines "hcall-instructions" device-tree property which contains code to call hypercalls in ePAPR paravirtualized guests. In general pseries guests won't use this property, instead using the PAPR defined hypercall interface. However, this property has been re-used to implement a hack to allow PR KVM to run (slightly modified) guests in some situations where it otherwise wouldn't be able to (because the system's L0 hypervisor doesn't forward the PAPR hypercalls to the PR KVM kernel). Hence, this property is always present in the device tree for pseries guests. All KVM guests use it at least to read features via the KVM_HC_FEATURES hypercall. The property is populated by the code returned from the KVM's KVM_PPC_GET_PVINFO ioctl; if not implemented in the KVM, QEMU supplies code which will fail all hypercall attempts. If QEMU does not create the property, and the guest kernel is compiled with CONFIG_EPAPR_PARAVIRT (which is normally the case), there is exactly the same stub at @epapr_hypercall_start already. Rather than maintaining this fairly useless stub implementation, it makes more sense not to create the property in the device tree in the first place if the host kernel does not implement it. This changes kvmppc_get_hypercall() to return 1 if the host kernel does not implement KVM_CAP_PPC_GET_PVINFO. The caller can use it to decide on whether to create the property or not. This changes the pseries machine to not create the property if KVM does not implement KVM_PPC_GET_PVINFO. In practice this means that from now on the property will not be created if either HV KVM or TCG is used.
