2016-06-07spapr_iommu: Migrate full stateAlexey Kardashevskiy1-0/+2
The source guest could have reallocated the default TCE table and migrate bigger/smaller table. This adds reallocation in post_load() if the default table size is different on source and destination. This adds @bus_offset, @page_shift to the migration stream as a subsection so when DDW is added, migration to older machines will still be possible. As @bus_offset and @page_shift are not used yet, this makes no change in behavior. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2016-06-03e1000e: Fix build with ust trace backendDmitry Fleytman1-1/+2
ust trace backend has limitation of maximum 10 arguments per event. Traces with more arguments cannot be compiled for this backend. Trace e1000e_rx_rss_ip6 introduced by previous commits has 11 arguments and fails to compile with ust trace backend. This patch fixes the problem by splitting this tracepoint into two successive tracepoints with smaller number of arguments. For more information see comment regarding TP_ARGS in lttng/tracepoint.h: /* * TP_ARGS takes tuples of type, argument separated by a comma. * It can take up to 10 tuples (which means that less than 10 tuples is * fine too). * Each tuple is also separated by a comma. */ Build log generated by this problem: In file included from ./trace/generated-tracers.h:9:0, from /home/travis/build/qemu/qemu/include/trace.h:4, from util/oslib-posix.c:36: ./trace/generated-ust-provider.h:16556:3: error: unknown type name ‘_TP_EXPROTO_Bool’ In file included from /home/travis/build/qemu/qemu/include/trace.h:4:0, from util/oslib-posix.c:36: ./trace/generated-tracers.h: In function ‘trace_e1000e_rx_rss_ip6’: ./trace/generated-tracers.h:8379:431: error: expected string literal before ‘_SDT_ASM_OPERANDS_ipv6_enabled’ ./trace/generated-tracers.h:8379:431: error: implicit declaration of function ‘__tracepoint_cb_qemu___e1000e_rx_rss_ip6’ [-Werror=implicit-function-declaration] ./trace/generated-tracers.h:8379:431: error: nested extern declaration of ‘__tracepoint_cb_qemu___e1000e_rx_rss_ip6’ [-Werror=nested-externs] cc1: all warnings being treated as errors make: *** [util/oslib-posix.o] Error 1 make: *** Waiting for unfinished jobs....

2016-06-02net: Introduce e1000e device emulationDmitry Fleytman1-0/+160
This patch introduces emulation for the Intel 82574 adapter, AKA e1000e. This implementation is derived from the e1000 emulation code, and utilizes the TX/RX packet abstractions that were initially developed for the vmxnet3 device. Although some parts of the introduced code may be shared with e1000, the differences are substantial enough so that the only shared resources for the two devices are the definitions in hw/net/e1000_regs.h. Similarly to vmxnet3, the new device uses virtio headers for task offloads (for backends that support virtio extensions). Usage of virtio headers may be forcibly disabled via a boolean device property "vnet" (which is enabled by default). In such case task offloads will be performed in software, in the same way it is done on backends that do not support virtio headers. The device code is split into two parts: 1. hw/net/e1000e.c: QEMU-specific code for a network device; 2. hw/net/e1000e_core.[hc]: Device emulation according to the spec. The new device name is e1000e. Intel specifications for the 82574 controller are available at: http://www.intel.com/content/dam/doc/datasheet/82574l-gbe-controller-datasheet.pdf Throughput measurement results (iperf2): Fedora 22 guest, TCP, RX 4 ++------------------------------------------+ | | | X X X X X 3.5 ++ X X X X | | X | | | 3 ++ | G | X | b | | / 2.5 ++ | s | | | | 2 ++ | | | | | 1.5 X+ | | | + + + + + + + + + + + + 1 ++--+---+---+---+---+---+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Fedora 22 guest, TCP, TX 18 ++-------------------------------------------+ | X | 16 ++ X X X X X | X | 14 ++ | | | 12 ++ | G | X | b 10 ++ | / | | s 8 ++ | | | 6 ++ X | | | 4 ++ | | X | 2 ++ X | X + + + + + + + + + + + 0 ++--+---+---+---+---+----+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Fedora 22 guest, UDP, RX 3 ++------------------------------------------+ | X | | 2.5 ++ | | | | | 2 ++ X | G | | b | | / 1.5 ++ | s | X | | | 1 ++ | | | | X | 0.5 ++ | | X | X + + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Fedora 22 guest, UDP, TX 1 ++------------------------------------------+ | X 0.9 ++ | | | 0.8 ++ | 0.7 ++ | | | G 0.6 ++ | b | | / 0.5 ++ | s | X | 0.4 ++ | | | 0.3 ++ | 0.2 ++ X | | | 0.1 ++ X | X X + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Windows 2012R2 guest, TCP, RX 3.2 ++------------------------------------------+ | X | 3 ++ | | | 2.8 ++ | | | 2.6 ++ X | G | X X X X X b 2.4 ++ X X | / | | s 2.2 ++ | | | 2 ++ | | X X | 1.8 ++ | | | 1.6 X+ | + + + + + + + + + + + + 1.4 ++--+---+---+---+---+---+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Windows 2012R2 guest, TCP, TX 14 ++-------------------------------------------+ | | | X X 12 ++ | | | 10 ++ | | | G | | b 8 ++ | / | X | s 6 ++ | | | | | 4 ++ X | | | 2 ++ | | X X X | + X X + + X X + + + + + 0 X+--+---+---+---+---+----+---+---+---+---+---+ 32 64 128 256 512 1 2 4 8 16 32 64 B B B B B KB KB KB KB KB KB KB Buffer size Windows 2012R2 guest, UDP, RX 1.6 ++------------------------------------------X | | 1.4 ++ | | | 1.2 ++ | | X | | | G 1 ++ | b | | / 0.8 ++ | s | | 0.6 ++ X | | | 0.4 ++ | | X | | | 0.2 ++ X | X + + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Windows 2012R2 guest, UDP, TX 0.6 ++------------------------------------------+ | X | | 0.5 ++ | | | | | 0.4 ++ | G | | b | | / 0.3 ++ X | s | | | | 0.2 ++ | | | | X | 0.1 ++ | | X | X X + + + + 0 ++-------+--------+-------+--------+--------+ 32 64 128 256 512 1 B B B B B KB Datagram size Signed-off-by: Dmitry Fleytman <dmitry.fleytman@ravellosystems.com> Signed-off-by: Leonid Bloch <leonid.bloch@ravellosystems.com> Reviewed-by: Michael S.
