2021-06-16bitops.h: Provide hswap32(), hswap64(), wswap64() swapping operationsPeter Maydell
Currently the ARM SVE helper code defines locally some utility functions for swapping 16-bit halfwords within 32-bit or 64-bit values and for swapping 32-bit words within 64-bit values, parallel to the byte-swapping bswap16/32/64 functions. We want these also for the ARM MVE code, and they're potentially generally useful for other targets, so move them to bitops.h. (We don't put them in bswap.h with the bswap* functions because they are implemented in terms of the rotate operations also defined in bitops.h, and including bitops.h from bswap.h seems better avoided.)

2021-06-11tcg: Move in_code_gen_buffer and tests to region.cRichard Henderson
Shortly, the full code_gen_buffer will only be visible to region.c, so move in_code_gen_buffer out-of-line. Move the debugging versions of tcg_splitwx_to_{rx,rw} to region.c as well, so that the compiler gets to see the implementation of in_code_gen_buffer. This leaves exactly one use of in_code_gen_buffer outside of region.c, in cpu_restore_state. Which, being on the exception path, is not performance critical.

Longer story: Without the space, kerneldoc generates a line like this: one of :c:type:`MemoryListener.region_add\(\) <MemoryListener>`,:c:type:`MemoryListener.region_del\(\) Sphinx does not process the role information correctly, so we get this (my pseudo-notation) construct: <text>,:c:type:</text> <reference target="MemoryListener">MemoryListener.region_del()</reference> which does not reference the desired entity, and leaves some extra junk in the rendered output.

2021-06-04qemu-config: parse configuration files to a QDictPaolo Bonzini
Change the parser to put the values into a QDict and pass them to a callback. qemu_config_parse's QemuOpts creation is itself turned into a callback function. This is useful for -readconfig to support keyval-based options; getting a QDict from the parser removes a roundtrip from QDict to QemuOpts and then back to QDict. Unfortunately there is a disadvantage in that semantic errors will point to the last line of the group, because the entries of the QDict do not have a location attached.

2021-06-03arm: Consistently use "Cortex-Axx", not "Cortex Axx"Peter Maydell
The official punctuation for Arm CPU names uses a hyphen, like "Cortex-A9". We mostly follow this, but in a few places usage without the hyphen has crept in. Fix those so we consistently use the same way of writing the CPU name. This commit was created with: git grep -z -l 'Cortex ' | xargs -0 sed -i 's/Cortex /Cortex-/' Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Message-id: 20210527095152.10968-1-peter.maydell@linaro.org
2021-06-03target/arm: Allow board models to specify initial NS VTORPeter Maydell
Currently we allow board models to specify the initial value of the Secure VTOR register, using an init-svtor property on the TYPE_ARMV7M object which is plumbed through to the CPU. Allow board models to also specify the initial value of the Non-secure VTOR via a similar init-nsvtor property.

into staging ppc patch queue 2021-06-03 Next batch of ppc target patches. Highlights are: * A fix for a regression with single-step mode * Start of moving ppc to use decodetree * Implementation of some POWER10 64-bit prefixed instructions * Several cleanups to softmmu code * Continued progress towards allowing --disable-tcg * Fix for the POWER PEF implementation * Fix for LPCR handling of hotplugged CPUs * Assorted other bugfixes and cleanups This patchset does contain a couple of changes to code outside my normal scope of maintainership, related to the removal of cpu_dump and cpu_statistics hooks. ppc was the last target arch implementing these at all, and they didn't really do anything there either. The patches should have relevant acks. # gpg: Signature made Thu 03 Jun 2021 09:20:59 BST # gpg: using RSA key 75F46586AE61A66CC44E87DC6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" [full] # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" [full] # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" [full] # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" [unknown] # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dg-gitlab/tags/ppc-for-6.1-20210603: (42 commits) target/ppc: fix single-step exception regression target/ppc: Move cmp/cmpi/cmpl/cmpli to decodetree target/ppc: Move addpcis to decodetree target/ppc: Implement vcfuged instruction target/ppc: Implement cfuged instruction target/ppc: Implement setbc/setbcr/stnbc/setnbcr instructions target/ppc: Implement prefixed integer store instructions target/ppc: Move D/DS/X-form integer stores to decodetree target/ppc: Implement prefixed integer load instructions target/ppc: Move D/DS/X-form integer loads to decodetree target/ppc: Implement PNOP target/ppc: Move ADDI, ADDIS to decodetree, implement PADDI target/ppc: Add infrastructure for prefixed insns target/ppc: Move page crossing check to ppc_tr_translate_insn target/ppc: Introduce macros to check isa extensions target/ppc: powerpc_excp: Consolidade TLB miss code target/ppc: powerpc_excp: Remove dump_syscall_vectored target/ppc: powerpc_excp: Move lpes code to where it is used target/ppc: overhauled and moved logic of storing fpscr target/ppc: removed all mentions to PPC_DUMP_CPU ...

2021-06-03spapr: Don't hijack current_machine->boot_orderGreg Kurz
QEMU 6.0 moved all the -boot variables to the machine. Especially, the removal of the boot_order static changed the handling of '-boot once' from: if (boot_once) { qemu_boot_set(boot_once, &error_fatal); qemu_register_reset(restore_boot_order, g_strdup(boot_order)); } to if (current_machine->boot_once) { qemu_boot_set(current_machine->boot_once, &error_fatal); qemu_register_reset(restore_boot_order, g_strdup(current_machine->boot_order)); } This means that we now register as subsequent boot order a copy of current_machine->boot_once that was just set with the previous call to qemu_boot_set(), i.e. we never transition away from the once boot order. It is certainly fragile^Wwrong for the spapr code to hijack a field of the base machine type object like that. The boot order rework simply turned this software boundary violation into an actual bug. Have the spapr code to handle that with its own field in SpaprMachineState. Also kfree() the initial boot device string when "once" was used.
