2017-05-11target/ppc: Set UPRT and GTSE on all cpus in H_REGISTER_PROCESS_TABLESuraj Jitindar Singh
The UPRT and GTSE bits are set when a guest calls H_REGISTER_PROCESS_TABLE to choose determine how address translation is performed. Currently these bits in the LPCR are only set for the cpu which handles the H_CALL, however they need to be set for all cpus for that guest as address translation cannot be performed differently on a per cpu basis. Update the H_CALL handler to set these bits in the LPCR correctly for all cpus of the guest. Note it is the reponsibility of the guest to ensure that any secondary cpus are suspended when the H_CALL is made and thus we can safely update these values here.

2017-05-11ppc/xics: preserve P and Q bits for KVM IRQsSam Bobroff
Kernel commit 17d48610ae0f ("KVM: PPC: Book 3S: XICS: Implement ICS P/Q states") added new bits to the state used by KVM IRQs. Currently, QEMU does not preserve these bits, so migrating (or otherwise saving and restoring) the guest state causes the P and Q bits to be cleared. Clearing the P bit has no effect, because the kernel will set it based on other data, but the loss of a set Q bit will cause a lost interrupt. This patch preserves the P and Q bits, correcting the problem. Signed-off-by: Sam Bobroff <sam.bobroff@au1.ibm.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2017-05-11ppc/pnv: restrict BMC object to the BMC simulatorCédric Le Goater
Today, when a PowerNV guest runs, it uses the sensor definitions of the BMC simulator to populate the device tree. But an external IPMI BMC could also be used and, in that case, it is not (yet) possible to retrieve the sensor list. Generating the OEM SEL event for shutdown or reboot also does not make sense as it should be generated on the BMC side. This change allows a guest to use an 'ipmi-bmc-extern' backend to the 'isa-ipmi-bt' device and a 'chardev' for transport such as : -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 \ -device ipmi-bmc-extern,id=bmc0,chardev=ipmi0 \ -device isa-ipmi-bt,bmc=bmc0,irq=10 and connect to a BMC simulator, the OpenIPMI ipmi_sim simulator for instance.

2017-05-10pc/fwcfg: unbreak migration from qemu-2.5 and qemu-2.6 during firmware bootIgor Mammedov
Since 2.7 commit (b2a575a Add optionrom compatible with fw_cfg DMA version) regressed migration during firmware exection time by abusing fwcfg.dma_enabled property to decide loading dma version of option rom AND by mistake disabling DMA for 2.6 and earlier globally instead of only for option rom. so 2.6 machine type guest is broken when it already runs firmware in DMA mode but migrated to qemu-2.7(pc-2.6) at that time; a) qemu-2.6:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport) b) qemu-2.7:pc2.6 (fwcfg.dma=off,firmware=ioport,oprom=ioport) to: a b from a OK FAIL b OK OK So we currently have broken forward migration from qemu-2.6 to qemu-2.[789] that however could be fixed for 2.10 by re-enabling DMA for 2.[56] machine types and allowing dma capable option rom only since 2.7. As result qemu should end up with: c) qemu-2.10:pc2.6 (fwcfg.dma=on,firmware=dma,oprom=ioport) to: a b c from a OK FAIL OK b OK OK OK c OK FAIL OK where forward migration from qemu-2.6 to qemu-2.10 should work again leaving only qemu-2.[789]:pc-2.6 broken.

2017-05-10hw/virtio: fix vhost user fails to startup when MQZhiyong Yang
Qemu2.7~2.9 and vhost user for dpdk 17.02 release work together to cause failures of new connection when negotiating to set MQ. (one queue pair works well). Because there exist some bugs in qemu code when introducing VHOST_USER_PROTOCOL_F_REPLY_ACK to qemu. When vhost_user_set_mem_table is invoked to deal with the vhost message VHOST_USER_SET_MEM_TABLE for the second time, qemu indeed doesn't send the messge (The message needs to be sent only once)but still will be waiting for dpdk's reply ack, then, qemu is always freezing, while DPDK is always waiting for next vhost message from qemu. The patch aims to fix the bug, MQ can work well. The same bug is found in function vhost_user_net_set_mtu, it is fixed at the same time.

2017-05-10hw/arm/virt: generate 64-bit addressable ACPI objectsArd Biesheuvel
Our current ACPI table generation code limits the placement of ACPI tables to 32-bit addressable memory, in order to be able to emit the root pointer (RSDP) and root table (RSDT) using table types from the ACPI 1.0 days. Since ARM was not supported by ACPI before version 5.0, it makes sense to lift this restriction. This is not crucial for mach-virt, which is guaranteed to have some memory available below the 4 GB mark, but it is a nice to have for QEMU machines that do not have any 32-bit addressable memory, which is not uncommon for real world 64-bit ARM systems. Since we already emit a version of the RSDP root pointer that has a secondary 64-bit wide address field for the 64-bit root table (XSDT), all we need to do is replace the RSDT generation with the generation of an XSDT table, and use a different slot in the FADT table to refer to the DSDT.

2017-05-04s390x/3270: Mark non-migratable and enable the deviceJing Liu
Mark 3270 as non-migratable for the experimental stage. Enable the 3270 device so that we can use x3270 client to operate the guest. Run qemu with the arguments: -chardev socket,id=char3270_0,host=0.0.0.0,port=23,nowait,server,tn3270 \ -device x-terminal3270,chardev=char3270_0,devno=fe.0.000a,id=terminal3270_0 \ There are some restrictions for the first stage: We don't support SSL connections, multiple client connections and client resizing. Only tested with the x3270 client.

2017-05-04s390x/3270: Detect for continued presence of a 3270 clientJing Liu
To ensure that we do not keep any 3270 sockets where the client is not connected anymore, we send a packet with the timing mark option after ten minutes of client inactivity. If the client does not answer it, then the socket will be closed automatically. This helps to ensure that there is no half-open situation on the 3270 socket.

After the client connected and TN3270 handshake done, signal the not-ready to ready status by an unsolicited device-end interrupt, and then the 3270 data stream could be handled correctly between the channel and socket. Multiple commands generated by "Reset" key on x3270 are not supported now, just simply terminate the connection.
