2017-02-07rules: don't try to create missing include dirsDaniel P. Berrange1-1/+1
In commit ba78db44f6532d66a1e704bd44613e841baa2fc5 Author: Daniel P. Berrange <berrange@redhat.com> Date: Wed Jan 25 16:14:10 2017 +0000 make: move top level dir to end of include search path The dir $(BUILD_DIR)/$(@D) was added to the include path. This would sometimes point to a non-existant directory, if the sub-dir in question did not contain any target-independant files (eg tcg/). To deal with this the rules.mak attempted to create the directory. While this was succesful, it also caused accidental creation of files in the parent of the build dir. e.g. when building common source files into target specific output files. Rather than trying to workaround this, just revert the code that attempted to mkdir the missing include directories. Instead just turn off the compiler warning in question as the missing dir is expected & harmless in general. NB: you can clean up a build directory parent that has been filled with empty directories by commit ba78db44f653 using this GNU find command in that parent directory: find audio backends block chardev crypto disas fsdev hw io linux-user \ migration nbd net qapi qom replay slirp target ui util \ -type d -empty -delete Signed-off-by: Daniel P.

2016-11-29rules.mak: Also try -r to build modulesPaolo Bonzini1-2/+8
Building qemu fails in distributions where gcc enables PIE by default (e.g. Debian unstable) with: /usr/bin/ld: -r and -pie may not be used together You have to use -r instead of -Wl,-r to avoid gcc passing -pie to the linker when PIE is enabled and a relocatable object is passed. However, clang does not know about -r, so try -Wl,-r first. [This is a fix for commit c96f0ee6a67ca6277366e78ce5d84d5c20dd596f ("rules.mak: Use -r instead of -Wl, -r to fix building when PIE is default") which mostly worked but broke the ./configure --enable-modules build with clang. --Stefan] Reported-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-id: 20161129153720.29747-1-pbonzini@redhat.com Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

On systems which do not provide ncursesw.pc and whose /usr/include/curses.h does not include wide support, we should not only try with no -I, i.e. /usr/include, but also with -I/usr/include/ncursesw. To properly detect for wide support with and without -Werror, we need to check for the presence of e.g. the WACS_DEGREE macro. We also want to stop at the first curses_inc_list configuration which works, and make sure to set IFS to : at each new loop.

2016-10-31sockets: add AF_VSOCK supportStefan Hajnoczi1-0/+31
Add the AF_VSOCK address family so that qemu-ga will be able to use virtio-vsock. The AF_VSOCK address family uses <cid, port> address tuples. The cid is the unique identifier comparable to an IP address. AF_VSOCK does not use name resolution so it's easy to convert between struct sockaddr_vm and strings. This patch defines a VsockSocketAddress instead of trying to piggy-back on InetSocketAddress. This is cleaner in the long run since it avoids lots of IPv4 vs IPv6 vs vsock special casing.

2016-10-11build: Work around SIZE_MAX bug in OSX headersEric Blake1-0/+16
C99 requires SIZE_MAX to be declared with the same type as the integral promotion of size_t, but OSX mistakenly defines it as an 'unsigned long long' expression even though size_t is only 'unsigned long'. Rather than futzing around with whether size_t is 32- or 64-bits wide (which would be needed if we cared about using SIZE_T in a #if expression), just hard-code it with a cast. This is not a strict C99-compliant definition, because it doesn't work in the preprocessor, but if we later need that, the build will break on Mac to inform us to improve our replacement at that time. See also https://patchwork.ozlabs.org/patch/542327/ for an instance where the wrong type trips us up if we don't fix it for good in osdep.h. Some versions of glibc make a similar mistake with SSIZE_MAX; the goal is that the approach of this patch could be copied to work around that problem if it ever becomes important to us.

Copy data operated on during request from/to local buffers to/from the grant references. Before grant copy operation local buffers must be allocated what is done by calling ioreq_init_copy_buffers. For the 'read' operation, first, the qemu device invokes the read operation on local buffers and on the completion grant copy is called and buffers are freed. For the 'write' operation grant copy is performed before invoking write by qemu device. A new value 'feature_grant_copy' is added to recognize when the grant copy operation is supported by a guest.

2016-09-13configure: Always compile with -fwrapvPeter Maydell1-1/+5
QEMU's code relies on left shifts of signed integers always being defined behaviour with the obvious 2s-complement semantics. The only way to tell the compiler (and any associated undefined-behaviour sanitizer) that we require a C dialect with these semantics is to use the -fwrapv option. This is a bit of a heavy hammer for the job as it also gives us guaranteed semantics on integer arithmetic overflow which in theory we don't require. In an ideal world this would allow us to drop the warning flag -Wno-shift-negative-value, but we must retain this to avoid spurious warnings on clang versions predating the fix to https://llvm.org/bugs/show_bug.cgi?id=25552.

2016-08-15pc-bios/optionrom: Fix OpenBSD build with better detection of linker emulationPeter Maydell1-1/+11
The various host OSes are irritatingly variable about the name of the linker emulation we need to pass to ld's -m option to build the i386 option ROMs. Instead of doing this via a CONFIG ifdef, check in configure whether any of the emulation names we know about will work and pass the right answer through to the makefile. If we can't find one, we fall back to not trying to build the option ROMs, in the same way we would for a non-x86 host platform. This is in particular necessary to unbreak the build on OpenBSD, since it wants a different answer to FreeBSD and we don't have an existing CONFIG_ variable that distinguishes the two.

2016-08-09Disable warn about left shifts of negative valuesPranith Kumar1-1/+1
It seems like there's no good reason for the compiler to exploit the undefinedness of left shifts. GCC explicitly documents that they do not use at all this possibility and, while they also say this is subject to change, they have been saying this for 10 years (since the wording appeared in the GCC 4.0 manual). Disable these warnings by passing in -Wno-shift-negative-value.

2016-07-25configure: mark qemu-ga VSS includes as system headersMichael Roth1-3/+3
As of e4650c81, we do w32 builds with -Werror enabled. Unfortunately for cases where we enable VSS support in qemu-ga, we still have warnings generated by VSS includes that ship as part of the Microsoft VSS SDK. We can selectively address a number of these warnings using #pragma GCC diagnostic ignored ... but at least one of these: warning: ‘typedef’ was ignored in this declaration resulting from declarations of the form: typedef struct Blah { ... }; does not provide a specific command-line/pragma option to disable warnings of the sort. To allow VSS builds to succeed, the next-best option is disabling these warnings on a per-file basis. pragmas like #pragma GCC system_header can be used to declare subsequent includes/declarations as being exempt from normal warnings, but this must be done within a header file. Since we don't control the VSS SDK, we'd need to rely on a intermediate header include to accomplish this, and since different objects in the VSS link target rely on different headers from the VSS SDK, this would become somewhat of a rat's nest (though not totally unmanageable). The next step up in granularity is just marking the entire VSS SDK include path as system headers via -isystem. This is a bit more heavy-handed, but since this SDK hasn't changed since 2005, there's likely little to be gained from selectively disabling warnings anyway, so we implement that approach here. This fixes the -Werror failures in both the configure test and the qga build due to shared reliance on $vss_win32_include. For the same reason, this also enforces a new dependency on -isystem support in the C/C++ compiler when building QGA with VSS enabled.

2016-07-22tests: introduce a framework for testing migration performanceDaniel P. Berrange1-0/+2
This introduces a moderately general purpose framework for testing performance of migration. The initial guest workload is provided by the included 'stress' program, which is configured to spawn one thread per guest CPU and run a maximally memory intensive workload. It will loop over GB of memory, xor'ing each byte with data from a 4k array of random bytes. This ensures heavy read and write load across all of guest memory to stress the migration performance. While running the 'stress' program will record how long it takes to xor each GB of memory and print this data for later reporting. The test engine will spawn a pair of QEMU processes, either on the same host, or with the target on a remote host via ssh, using the host kernel and a custom initrd built with 'stress' as the /init binary. Kernel command line args are set to ensure a fast kernel boot time (< 1 second) between launching QEMU and the stress program starting execution. None the less, the test engine will initially wait N seconds for the guest workload to stablize, before starting the migration operation. When migration is running, the engine will use pause, post-copy, autoconverge, xbzrle compression and multithread compression features, as well as downtime & bandwidth tuning to encourage completion. If migration completes, the test engine will wait N seconds again for the guest workooad to stablize on the target host. If migration does not complete after a preset number of iterations, it will be aborted. While the QEMU process is running on the source host, the test engine will sample the host CPU usage of QEMU as a whole, and each vCPU thread. While migration is running, it will record all the stats reported by 'query-migration'. Finally, it will capture the output of the stress program running in the guest. All the data produced from a single test execution is recorded in a structured JSON file. A separate program is then able to create interactive charts using the "plotly" python + javascript libraries, showing the characteristics of the migration. The data output provides visualization of the effect on guest vCPU workloads from the migration process, the corresponding vCPU utilization on the host, and the overall CPU hit from QEMU on the host. This is correlated from statistics from the migration process, such as downtime, vCPU throttling and iteration number. While the tests can be run individually with arbitrary parameters, there is also a facility for producing batch reports for a number of pre-defined scenarios / comparisons, in order to be able to get standardized results across different hardware configurations (eg TCP vs RDMA, or comparing different VCPU counts / memory sizes, etc). To use this, first you must build the initrd image $ make tests/migration/initrd-stress.img To run a a one-shot test with all default parameters $ ./tests/migration/guestperf.py > result.json This has many command line args for varying its behaviour. For example, to increase the RAM size and CPU count and bind it to specific host NUMA nodes $ ./tests/migration/guestperf.py \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 \ > result.json Using mem + cpu binding is strongly recommended on NUMA machines, otherwise the guest performance results will vary wildly between runs of the test due to lucky/unlucky NUMA placement, making sensible data analysis impossible. To make it run across separate hosts: $ ./tests/migration/guestperf.py \ --dst-host somehostname > result.json To request that post-copy is enabled, with switchover after 5 iterations $ ./tests/migration/guestperf.py \ --post-copy --post-copy-iters 5 > result.json Once a result.json file is created, a graph of the data can be generated, showing guest workload performance per thread and the migration iteration points: $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu result.json To further include host vCPU utilization and overall QEMU utilization $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu \ --qemu-cpu --vcpu-cpu result.json NB, the 'guestperf-plot.py' command requires that you have the plotly python library installed. eg you must do $ pip install --user plotly Viewing the result.html file requires that you have the plotly.min.js file in the same directory as the HTML output. This js file is installed as part of the plotly python library, so can be found in $HOME/.local/lib/python2.7/site-packages/plotly/offline/plotly.min.js The guestperf-plot.py program can accept multiple json files to plot, enabling results from different configurations to be compared. Finally, to run the entire standardized set of comparisons $ ./tests/migration/guestperf-batch.py \ --dst-host somehost \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 --output tcp-somehost-4gb-2cpu will store JSON files from all scenarios in the directory named tcp-somehost-4gb-2cpu Signed-off-by: Daniel P.
