2024-07-22plugins/stoptrigger: TCG plugin to stop execution under conditionsSimon Hamelin2-0/+152
This new plugin allows to stop emulation using conditions on the emulation state. By setting this plugin arguments, it is possible to set an instruction count limit and/or trigger address(es) to stop at. The code returned at emulation exit can be customized. This plugin demonstrates how someone could stop QEMU execution. It could be used for research purposes to launch some code and deterministically stop it and understand where its execution flow went.

2024-07-02contrib/vhost-user-blk: fix bind() using the right size of the addressStefano Garzarella1-3/+1
On macOS passing `-s /tmp/vhost.socket` parameter to the vhost-user-blk application, the bind was done on `/tmp/vhost.socke` pathname, missing the last character. This sounds like one of the portability problems described in the unix(7) manpage: Pathname sockets When binding a socket to a pathname, a few rules should be observed for maximum portability and ease of coding: • The pathname in sun_path should be null-terminated. • The length of the pathname, including the terminating null byte, should not exceed the size of sun_path. • The addrlen argument that describes the enclosing sockaddr_un structure should have a value of at least: offsetof(struct sockaddr_un, sun_path) + strlen(addr.sun_path)+1 or, more simply, addrlen can be specified as sizeof(struct sockaddr_un). So let's follow the last advice and simplify the code as well.

2024-06-24contrib/plugins: add Instructions Per Second (IPS) example for cost modelingPierrick Bouvier2-0/+165
This plugin uses the new time control interface to make decisions about the state of time during the emulation. The algorithm is currently very simple. The user specifies an ips rate which applies per core. If the core runs ahead of its allocated execution time the plugin sleeps for a bit to let real time catch up. Either way time is updated for the emulation as a function of total executed instructions with some adjustments for cores that idle. Examples -------- Slow down execution of /bin/true: $ num_insn=$(./build/qemu-x86_64 -plugin ./build/tests/plugin/libinsn.so -d plugin /bin/true |& grep total | sed -e 's/.*: //') $ time ./build/qemu-x86_64 -plugin ./build/contrib/plugins/libips.so,ips=$(($num_insn/4)) /bin/true real 4.000s Boot a Linux kernel simulating a 250MHz cpu: $ /build/qemu-system-x86_64 -kernel /boot/vmlinuz-6.1.0-21-amd64 -append "console=ttyS0" -plugin ./build/contrib/plugins/libips.so,ips=$((250*1000*1000)) -smp 1 -m 512 check time until kernel panic on serial0 Tested in system mode by booting a full debian system, and using: $ sysbench cpu run Performance decrease linearly with the given number of ips.

2024-02-28contrib/plugins: extend execlog to track register changesAlex Bennée1-51/+265
With the new plugin register API we can now track changes to register values. Currently the implementation is fairly dumb which will slow down if a large number of register values are being tracked. This could be improved by only instrumenting instructions which mention registers we are interested in tracking. Example usage: ./qemu-aarch64 -D plugin.log -d plugin \ -cpu max,sve256=on \ -plugin contrib/plugins/libexeclog.so,reg=sp,reg=z\* \ ./tests/tcg/aarch64-linux-user/sha512-sve will display in the execlog any changes to the stack pointer (sp) and the SVE Z registers. As testing registers every instruction will be quite a heavy operation there is an additional flag which attempts to optimise the register tracking by only instrumenting instructions which are likely to change its value. This relies on the QEMU disassembler showing up the register names in disassembly so is an explicit opt-in.

2023-11-23plugins: fix win plugin tests on cross compileGreg Manning1-1/+1
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1972 Cross compile gcc is more picky about argument order than msys. Changed the meson command to take the (now renamed) libqemu_plugin_api.a as a lib, rather than an object.
