2024-02-28contrib/plugins: extend execlog to track register changesAlex Bennée
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.

2023-09-21elf2dmp: introduce physical block alignmentViktor Prutyanov
Physical memory ranges may not be aligned to page size in QEMU ELF, but DMP can only contain page-aligned runs. So, align them.

2023-09-21elf2dmp: replace PE export name check with PDB name checkViktor Prutyanov
PE export name check introduced in d399d6b179 isn't reliable enough, because a page with the export directory may be not present for some reason. On the other hand, elf2dmp retrieves the PDB name in any case. It can be also used to check that a PE image is the kernel image. So, check PDB name when searching for Windows kernel image.

2023-09-12contrib/vhost-user-gpu: add support for sending dmabuf modifiersErico Nunes
virglrenderer recently added virgl_renderer_resource_get_info_ext as a new api, which gets resource information, including dmabuf modifiers. We have to support dmabuf modifiers since the driver may choose to allocate buffers with these modifiers for efficiency, and importing buffers without modifiers information may result in completely broken rendering.

2023-09-07contrib/plugins: use an independent makefilePaolo Bonzini
The initial reason to write this patch was to remove the last use of CONFIG_DEBUG_TCG from the makefiles; the flags to use to build TCG plugins are unrelated to --enable-debug-tcg, and instead they should be the same as those used to build emulators (the plugins are not build via meson for demonstration reasons only). However, since contrib/plugins/Makefile is also the last case of doing a compilation job using config-host.mak, go a step further and make it use a completely separate configuration file, removing all references to compilers from the toplevel config-host.mak. Clean up references to empty variables, and use .SECONDARY so that intermediate object files are not deleted. Reviewed-by: Daniel P.

Under Darwin, using -shared makes it impossible to have undefined symbols and -bundle has to be used instead; so detect the OS and use different options. Based-on: <20230907101811.469236-1-pbonzini@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
