| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent binutils changes dropping unsupported options [1] caused a build issue in regard to the optionroms. ld -m elf_i386 -T /<<PKGBUILDDIR>>/pc-bios/optionrom//flat.lds -no-pie \ -s -o multiboot.img multiboot.o ld.bfd: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?) This isn't really a regression in ld.bfd, filing the bug upstream revealed that this never worked as a ld flag [2] - in fact it seems we were by accident setting --nmagic). Since it never had the wanted effect this usage of LDFLAGS_NOPIE, should be droppable without any effect. This also is the only use-case of LDFLAGS_NOPIE in .mak, therefore we can also remove it from being added there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A QemuOptsList can be of one of two kinds: either it is pre-validated, or it accepts any key and validation happens somewhere else (typically in a Visitor or against a list of QOM properties). opts_accepts_any returns true if a QemuOpts instance was created from a QemuOptsList of the latter kind, but there is no function to do the check on a QemuOptsList. Since this property comes from the QemuOptsList and almost all callers of opts_accepts_any use opts->list anyway, modify the function to accept QemuOptsList.

| * kvm: Take into account the unaligned section size when preparing bitmapZenghui Yu2020-12-151-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel KVM_CLEAR_DIRTY_LOG interface has align requirement on both the start and the size of the given range of pages. We have been careful to handle the unaligned cases when performing CLEAR on one slot. But it seems that we forget to take the unaligned *size* case into account when preparing bitmap for the interface, and we may end up clearing dirty status for pages outside of [start, start + size). If the size is unaligned, let's go through the slow path to manipulate a temp bitmap for the interface so that we won't bother with those unaligned bits at the end of bitmap. I don't think this can happen in practice since the upper layer would provide us with the alignment guarantee. I'm not sure if kvm-all could rely on it. And this patch is mainly intended to address correctness of the specific algorithm used inside kvm_log_clear_one_slot().

| * memory: clamp cached translation in case it points to an MMIO regionPaolo Bonzini2020-12-152-0/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since NVDIMM support was introduced on pseries machine, it ignored machine's nvdimm=on|off option and effectively was always enabled on machines that support NVDIMM. Later on commit (28f5a716212 ppc/spapr_nvdimm: do not enable support with 'nvdimm=off') makes QEMU error out in case user explicitly set 'nvdimm=off' on CLI by peeking at machine_opts. However that's a workaround and leaves 'nvdimms_state->is_enabled' in inconsistent state (false) when it should be set true by default. Instead of using on machine_opts, set default to true for pseries machine in initfn time. If user sets manually 'nvdimm=off' it will overwrite default value to false and QEMU will error as expected without need to peek into machine_opts. That way pseries will have, nvdimm enabled by default and will honor user provided 'nvdimm=on|off'.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Leave only consistency checks and gdbserver processing in qemu_machine_creation_done. gdbserver_start can be moved after qdev_machine_creation_done because it only does listen on the socket and creates some internal data structures; it does not send any data (e.g. guest state) over the socket.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Numonyx chips determine the number of cycles to wait based on bits 7:4 in the volatile configuration register. However, if these bits are 0x0 or 0xF, the number of dummy cycles to wait is 10 for QIOR and QIOR4 commands or when in QIO mode, and otherwise 8 for the currently supported fast read commands.
