2023-11-14dump: Add arch cleanup functionJanosch Frank
Some architectures (s390x) need to cleanup after a failed dump to be able to continue to run the vm. Add a cleanup function pointer and call it if it's set.

git://git.infradead.org/users/dwmw2/qemu into staging Bugfixes for emulated Xen support Selected bugfixes for mainline and stable, especially to the per-vCPU local APIC vector delivery mode for event channel notifications, which was broken in a number of ways. The xen-block driver has been defaulting to the wrong protocol for x86 guest, and this fixes that — which is technically an incompatible change but I'm fairly sure nobody relies on the broken behaviour (and in production I *have* seen guests which rely on the correct behaviour, which now matches the blkback driver in the Linux kernel). A handful of other simple fixes for issues which came to light as new features (qv) were being developed. # -----BEGIN PGP SIGNATURE----- # # iQJIBAABCAAyFiEEvgfZ/VSAmrLEsP9fY3Ys2mfi81kFAmVIvv4UHGR3bXcyQGlu # ZnJhZGVhZC5vcmcACgkQY3Ys2mfi81nFmRAAvK3VNuGDV56TJqFdtEWD+3jzSZU0 # CoL1mxggvwnlFn1SdHvbC5jl+UscknErcNbqlxMTTg9jQiiQqzFuaWujJnL0dEOY # RJiS2scKln/1gv9NRbLE31FjPwoNz+zJI/iMvdutjT7Ll//v34jY0vd1Y5Wo53ay # MBschuuxD1sUUTHNj5f9afrgZaetJfgBSNZraiLR5T2HEadJVJuhItdGxW1+KaPI # zBIcflIeZmJl9b/L1a2bP3KJmRo8QzHB56X3uzwkPhYhYSU2dnCaJTLCkiNfK+Qh # SgCBMlzsvJbIZqDA9YPOGdKK1ArfTJRmRDwAkqH0YQknQGoIkpN+7eQiiSv6PMS5 # U/93V7r6MfaftIs6YdWSnFozWeBuyKZL9H2nAXqZgL5t6uEMVR8Un/kFnGfslTFY # 9gQ1o4IM6ECLiXhIP/sPNOprrbFb0HU7QPtEDJOxrJzBM+IfLbldRHn4p9CccqQA # LHvJF98VhX1d0nA0iZBT3qqfKPbmUhRV9Jrm+WamqNrRXhiGdF8EidsUf8RWX+JD # xZWJiqhTwShxdLE6TC/JgFz4cQCVHG8QiZstZUbdq59gtz9YO5PGByMgI3ds7iNQ # lGXAPFm+1wU85W4dZOH7qyim6d9ytFm2Fm110BKM8l9B6UKEuKHpsxXMqdo65JXI # 7uBKbVpdPKul0DY= # =dQ7h # -----END PGP SIGNATURE----- # gpg: Signature made Mon 06 Nov 2023 18:25:02 HKT # gpg: using RSA key BE07D9FD54809AB2C4B0FF5F63762CDA67E2F359 # gpg: issuer "dwmw2@infradead.org" # gpg: Good signature from "David Woodhouse <dwmw2@infradead.org>" [unknown] # gpg: aka "David Woodhouse <dwmw2@exim.org>" [unknown] # gpg: aka "David Woodhouse <david@woodhou.se>" [unknown] # gpg: aka "David Woodhouse <dwmw2@kernel.org>" [unknown] # gpg: WARNING: The key's User ID is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: BE07 D9FD 5480 9AB2 C4B0 FF5F 6376 2CDA 67E2 F359 * tag 'pull-xenfv-stable-20231106' of git://git.infradead.org/users/dwmw2/qemu: hw/xen: use correct default protocol for xen-block on x86 hw/xen: take iothread mutex in xen_evtchn_reset_op() hw/xen: fix XenStore watch delivery to guest hw/xen: don't clear map_track[] in xen_gnttab_reset() hw/xen: select kernel mode for per-vCPU event channel upcall vector i386/xen: fix per-vCPU upcall vector for Xen emulation i386/xen: Don't advertise XENFEAT_supervisor_mode_kernel Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2023-11-06hw/xen: select kernel mode for per-vCPU event channel upcall vectorDavid Woodhouse
A guest which has configured the per-vCPU upcall vector may set the HVM_PARAM_CALLBACK_IRQ param to fairly much anything other than zero. For example, Linux v6.0+ after commit b1c3497e604 ("x86/xen: Add support for HVMOP_set_evtchn_upcall_vector") will just do this after setting the vector: /* Trick toolstack to think we are enlightened. */ if (!cpu) rc = xen_set_callback_via(1); That's explicitly setting the delivery to GSI#1, but it's supposed to be overridden by the per-vCPU vector setting. This mostly works in Qemu *except* for the logic to enable the in-kernel handling of event channels, which falsely determines that the kernel cannot accelerate GSI delivery in this case. Add a kvm_xen_has_vcpu_callback_vector() to report whether vCPU#0 has the vector set, and use that in xen_evtchn_set_callback_param() to enable the kernel acceleration features even when the param *appears* to be set to target a GSI. Preserve the Xen behaviour that when HVM_PARAM_CALLBACK_IRQ is set to *zero* the event channel delivery is disabled completely. (Which is what that bizarre guest behaviour is working round in the first place.)

2023-11-02dump: Allow directly outputting raw kdump formatStephen Brennan
The flattened format (currently output by QEMU) is used by makedumpfile only when it is outputting a vmcore to a file which is not seekable. The flattened format functions essentially as a set of instructions of the form "seek to the given offset, then write the given bytes out". The flattened format can be reconstructed using makedumpfile -R, or makedumpfile-R.pl, but it is a slow process because it requires copying the entire vmcore. The flattened format can also be directly read by crash, but still, it requires a lengthy reassembly phase. To sum up, the flattened format is not an ideal one: it should only be used on files which are actually not seekable. This is the exact strategy which makedumpfile uses, as seen in the implementation of "write_buffer()" in makedumpfile [1]. However, QEMU has always used the flattened format. For compatibility it is best not to change the default output format without warning. So, add a flag to DumpState which changes the output to use the normal (i.e. raw) format. This flag will be added to the QMP and HMP commands in the next change.

2023-10-31util/defer-call: move defer_call() to util/Stefan Hajnoczi
The networking subsystem may wish to use defer_call(), so move the code to util/ where it can be reused. As a reminder of what defer_call() does: This API defers a function call within a defer_call_begin()/defer_call_end() section, allowing multiple calls to batch up. This is a performance optimization that is used in the block layer to submit several I/O requests at once instead of individually: defer_call_begin(); <-- start of section ... defer_call(my_func, my_obj); <-- deferred my_func(my_obj) call defer_call(my_func, my_obj); <-- another defer_call(my_func, my_obj); <-- another ... defer_call_end(); <-- end of section, my_func(my_obj) is called once Suggested-by: Ilya Maximets <i.maximets@ovn.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-ID: <20230913200045.1024233-3-stefanha@redhat.com> Reviewed-by: Michael S.

2023-10-12softmmu: pass the main loop status to gdb "Wxx" packetClément Chigot
gdb_exit function aims to close gdb sessions and sends the exit code of the current execution. It's being called by qemu_cleanup once the main loop is over. Until now, the exit code sent was always 0. Now that hardware can shutdown this main loop with custom exit codes, these codes must be transfered to gdb as well.

Add prepare callback to struct VMChangeStateEntry. The prepare callback is optional and can be set by the new function qemu_add_vm_change_state_handler_prio_full() that allows setting this callback in addition to the main callback. The prepare callbacks and main callbacks are called in two separate phases: First all prepare callbacks are called and only then all main callbacks are called. The purpose of the new prepare callback is to allow all devices to run a preliminary task before calling the devices' main callbacks. This will facilitate adding P2P support for VFIO migration where all VFIO devices need to be put in an intermediate P2P quiescent state before being stopped or started by the main callback.

kvm_get_apic_state() is only defined for x86 targets (in hw/i386/kvm/apic.c). Its declaration is pointless on all other targets.

2023-09-01os-posix.c, softmmu/vl.c: move os_parse_cmd_args() into qemu_init()Michael Tokarev
This will stop linking softmmu-specific os_parse_cmd_args() into every qemu executable which happens to use other functions from os-posix.c, such as os_set_line_buffering() or os_setup_signal_handling(). Also, since there's no win32-specific options, *all* option parsing is now done in softmmu/vl.c:qemu_init(), which is easier to read without extra indirection, - all options are in the single function now. This effectively reverts commit 59a5264b99434.

2023-08-31bulk: Do not declare function prototypes using 'extern' keywordPhilippe Mathieu-Daudé
By default, C function prototypes declared in headers are visible, so there is no need to declare them as 'extern' functions. Remove this redundancy in a single bulk commit; do not modify: - meson.build (used to check function availability at runtime) - pc-bios/ - libdecnumber/ - tests/ - *.c Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20230605175647.88395-5-philmd@linaro.org>
