2021-01-07util: Enhance flush_icache_range with separate data pointerRichard Henderson
We are shortly going to have a split rw/rx jit buffer. Depending on the host, we need to flush the dcache at the rw data pointer and flush the icache at the rx code pointer. For now, the two passed pointers are identical, so there is no effective change in behaviour.

2021-01-02vl: initialize displays _after_ exiting preconfigurationPaolo Bonzini
Due to the renumbering of text consoles when graphical consoles are created, init_displaystate must be called after all QemuConsoles are created, i.e. after devices are created. vl.c calls it from qemu_init_displays, while qmp_x_exit_preconfig is where devices are created.

2020-12-15memory: clamp cached translation in case it points to an MMIO regionPaolo Bonzini
In using the address_space_translate_internal API, address_space_cache_init forgot one piece of advice that can be found in the code for address_space_translate_internal: /* MMIO registers can be expected to perform full-width accesses based only * on their address, without considering adjacent registers that could * decode to completely different MemoryRegions. When such registers * exist (e.g. I/O ports 0xcf8 and 0xcf9 on most PC chipsets), MMIO * regions overlap wildly. For this reason we cannot clamp the accesses * here. * * If the length is small (as is the case for address_space_ldl/stl), * everything works fine. If the incoming length is large, however, * the caller really has to do the clamping through memory_access_size. */ address_space_cache_init is exactly one such case where "the incoming length is large", therefore we need to clamp the resulting length---not to memory_access_size though, since we are not doing an access yet, but to the size of the resulting section. This ensures that subsequent accesses to the cached MemoryRegionSection will be in range. With this patch, the enclosed testcase notices that the used ring does not fit into the MSI-X table and prints a "qemu-system-x86_64: Cannot map used" error.

2020-12-15vl: Add option to avoid stopping VM upon guest panicAlejandro Jimenez
The current default action of pausing a guest after a panic event is received leaves the responsibility to resume guest execution to the management layer. The reasons for this behavior are discussed here: https://lore.kernel.org/qemu-devel/52148F88.5000509@redhat.com/ However, in instances like the case of older guests (Linux and Windows) using a pvpanic device but missing support for the PVPANIC_CRASHLOADED event, and Windows guests using the hv-crash enlightenment, it is desirable to allow the guests to continue running after sending a PVPANIC_PANICKED event. This allows such guests to proceed to capture a crash dump and automatically reboot without intervention of a management layer. Add an option to avoid stopping a VM after a panic event is received, by passing: -action panic=none in the command line arguments, or during runtime by using an upcoming QMP command.

2020-12-15vl: Add an -action option specifying response to guest eventsAlejandro Jimenez
Several command line options currently in use are meant to modify the behavior of QEMU in response to certain guest events like: -no-reboot, -no-shutdown, -watchdog-action. These can be grouped into a single option of the form: -action event=action Which can be used to specify the existing options above in the following format: -action reboot=none|shutdown -action shutdown=poweroff|pause -action watchdog=reset|shutdown|poweroff|pause|debug|none|inject-nmi This is done in preparation for adding yet another option of this type, which modifies the QEMU behavior when a guest panic occurs.

2020-12-15chardev: do not use machine_init_donePaolo Bonzini
machine_init_done is not the right flag to check when preconfig is taken into account; for example "./qemu-system-x86_64 -serial mon:stdio -preconfig" does not print the QEMU monitor header until after exit_preconfig. Add back a custom bool for mux character devices. This partially undoes commit c7278b4355 ("chardev: introduce chr_machine_done hook", 2018-03-12), but it keeps the cleaner logic using a function pointer in ChardevClass.
