2023-11-24coverity: physmem: use simple assertions instead of modellingVladimir Sementsov-Ogievskiy1-0/+22
Unfortunately Coverity doesn't follow the logic aroung "len" and "l" variables in stacks finishing with flatview_{read,write}_continue() and generate a lot of OVERRUN false-positives. When small buffer (2 or 4 bytes) is passed to mem read/write path, Coverity assumes the worst case of sz=8 in stn_he_p()/ldn_he_p() (defined in include/qemu/bswap.h), and reports buffer overrun. To silence these false-positives we have model functions, which hide real logic from Coverity. However, it turned out that these new two assertions are enough to quiet Coverity. Assertions are better than hiding the logic, so let's drop the modelling and move to assertions for memory r/w call stacks. After patch, the sequence cov-make-library --output-file /tmp/master.xmldb \ scripts/coverity-scan/model.c cov-build --dir ~/covtmp/master make -j9 cov-analyze --user-model-file /tmp/master.xmldb \ --dir ~/covtmp/master --all --strip-path "$(pwd) cov-format-errors --dir ~/covtmp/master \ --html-output ~/covtmp/master_html_report Generate for me the same big set of CIDs excepept for 6 disappeared (so it becomes even better).

2023-11-21vl: revert behaviour for -display noneMarc-André Lureau1-1/+1
Commit 1bec1cc0d ("ui/console: allow to override the default VC") changed the behaviour of the "-display none" option, so that it now creates a QEMU monitor on the terminal. "-display none" should not be tangled up with whether we create a monitor or a serial terminal; it should purely and only disable the graphical window. Changing its behaviour like this breaks command lines which, for example, use semihosting for their output and don't want a graphical window, as they now get a monitor they never asked for. It also breaks the command line we document for Xen in docs/system/i386/xen.html: $ ./qemu-system-x86_64 --accel kvm,xen-version=0x40011,kernel-irqchip=split \ -display none -chardev stdio,mux=on,id=char0,signal=off -mon char0 \ -device xen-console,chardev=char0 -drive file=${GUEST_IMAGE},if=xen qemu-system-x86_64: cannot use stdio by multiple character devices qemu-system-x86_64: could not connect serial device to character backend 'stdio' When qemu is compiled without PIXMAN, by default the serials aren't muxed with the monitor anymore on stdio. The serials are redirected to "null" instead, and the monitor isn't set up.

2023-11-07system/cpus: Fix CPUState.nr_cores' calculationZhuocheng Ding1-1/+1
From CPUState.nr_cores' comment, it represents "number of cores within this CPU package". After 003f230e37d7 ("machine: Tweak the order of topology members in struct CpuTopology"), the meaning of smp.cores changed to "the number of cores in one die", but this commit missed to change CPUState.nr_cores' calculation, so that CPUState.nr_cores became wrong and now it misses to consider numbers of clusters and dies. At present, only i386 is using CPUState.nr_cores. But as for i386, which supports die level, the uses of CPUState.nr_cores are very confusing: Early uses are based on the meaning of "cores per package" (before die is introduced into i386), and later uses are based on "cores per die" (after die's introduction). This difference is due to that commit a94e1428991f ("target/i386: Add CPUID.1F generation support for multi-dies PCMachine") misunderstood that CPUState.nr_cores means "cores per die" when calculated CPUID.1FH.01H:EBX. After that, the changes in i386 all followed this wrong understanding. With the influence of 003f230e37d7 and a94e1428991f, for i386 currently the result of CPUState.nr_cores is "cores per die", thus the original uses of CPUState.cores based on the meaning of "cores per package" are wrong when multiple dies exist: 1. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.01H:EBX[bits 23:16] is incorrect because it expects "cpus per package" but now the result is "cpus per die". 2. In cpu_x86_cpuid() of target/i386/cpu.c, for all leaves of CPUID.04H: EAX[bits 31:26] is incorrect because they expect "cpus per package" but now the result is "cpus per die". The error not only impacts the EAX calculation in cache_info_passthrough case, but also impacts other cases of setting cache topology for Intel CPU according to cpu topology (specifically, the incoming parameter "num_cores" expects "cores per package" in encode_cache_cpuid4()). 3. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.0BH.01H:EBX[bits 15:00] is incorrect because the EBX of 0BH.01H (core level) expects "cpus per package", which may be different with 1FH.01H (The reason is 1FH can support more levels. For QEMU, 1FH also supports die, 1FH.01H:EBX[bits 15:00] expects "cpus per die"). 4. In cpu_x86_cpuid() of target/i386/cpu.c, when CPUID.80000001H is calculated, here "cpus per package" is expected to be checked, but in fact, now it checks "cpus per die". Though "cpus per die" also works for this code logic, this isn't consistent with AMD's APM. 5. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.80000008H:ECX expects "cpus per package" but it obtains "cpus per die". 6. In simulate_rdmsr() of target/i386/hvf/x86_emu.c, in kvm_rdmsr_core_thread_count() of target/i386/kvm/kvm.c, and in helper_rdmsr() of target/i386/tcg/sysemu/misc_helper.c, MSR_CORE_THREAD_COUNT expects "cpus per package" and "cores per package", but in these functions, it obtains "cpus per die" and "cores per die". On the other hand, these uses are correct now (they are added in/after a94e1428991f): 1. In cpu_x86_cpuid() of target/i386/cpu.c, topo_info.cores_per_die meets the actual meaning of CPUState.nr_cores ("cores per die"). 2. In cpu_x86_cpuid() of target/i386/cpu.c, vcpus_per_socket (in CPUID. 04H's calculation) considers number of dies, so it's correct. 3. In cpu_x86_cpuid() of target/i386/cpu.c, CPUID.1FH.01H:EBX[bits 15:00] needs "cpus per die" and it gets the correct result, and CPUID.1FH.02H:EBX[bits 15:00] gets correct "cpus per package". When CPUState.nr_cores is correctly changed to "cores per package" again , the above errors will be fixed without extra work, but the "currently" correct cases will go wrong and need special handling to pass correct "cpus/cores per die" they want. Fix CPUState.nr_cores' calculation to fit the original meaning "cores per package", as well as changing calculation of topo_info.cores_per_die, vcpus_per_socket and CPUID.1FH.

2023-11-07ui/console: allow to override the default VCMarc-André Lureau1-10/+17
If a display is backed by a specialized VC, allow to override the default "vc:80Cx24C". As suggested by Paolo, if the display doesn't implement a VC (get_vc() returns NULL), use a fallback that will use a muxed console on stdio. This changes the behaviour of "qemu -display none", to create a muxed serial/monitor by default (on TTY & not daemonized).

2023-11-07Add virtio-sound-pci deviceManos Pitsidianakis1-0/+1
This patch adds a PCI wrapper device for the virtio-sound device. It is necessary to instantiate a virtio-snd device in a guest. All sound logic will be added to the virtio-snd device in the following commits. To add this device with a guest, you'll need a >=5.13 kernel compiled with CONFIG_SND_VIRTIO=y, which at the time of writing most distros have off by default. Use with following flags in the invocation: Pulseaudio: -audio driver=pa,model=virtio or -audio driver=pa,model=virtio,server=/run/user/1000/pulse/native sdl: -audio driver=sdl,model=virtio coreaudio (macos/darwin): -audio driver=coreaudio,model=virtio etc. Based-on: https://github.com/OpenSynergy/qemu/commit/5a2f350eec5d157b90d9c7b40a8e603f4da92471 Signed-off-by: Igor Skalkin <Igor.Skalkin@opensynergy.com> Signed-off-by: Anton Yakovlev <Anton.Yakovlev@opensynergy.com> Signed-off-by: Manos Pitsidianakis <manos.pitsidianakis@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Tested-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <b223598d59f56ead6a6d8d9bb6801e17489ddaa4.1698062525.git.manos.pitsidianakis@linaro.org> Acked-by: Michael S.

2023-10-12memory,vhost: Allow for marking memory device memory regions unmergeableDavid Hildenbrand1-6/+25
Let's allow for marking memory regions unmergeable, to teach flatview code and vhost to not merge adjacent aliases to the same memory region into a larger memory section; instead, we want separate aliases to stay separate such that we can atomically map/unmap aliases without affecting other aliases. This is desired for virtio-mem mapping device memory located on a RAM memory region via multiple aliases into a memory region container, resulting in separate memslots that can get (un)mapped atomically. As an example with virtio-mem, the layout would look something like this: [...] 0000000240000000-00000020bfffffff (prio 0, i/o): device-memory 0000000240000000-000000043fffffff (prio 0, i/o): virtio-mem 0000000240000000-000000027fffffff (prio 0, ram): alias memslot-0 @mem2 0000000000000000-000000003fffffff 0000000280000000-00000002bfffffff (prio 0, ram): alias memslot-1 @mem2 0000000040000000-000000007fffffff 00000002c0000000-00000002ffffffff (prio 0, ram): alias memslot-2 @mem2 0000000080000000-00000000bfffffff [...] Without unmergable memory regions, all three memslots would get merged into a single memory section. For example, when mapping another alias (e.g., virtio-mem-memslot-3) or when unmapping any of the mapped aliases, memory listeners will first get notified about the removal of the big memory section to then get notified about re-adding of the new (differently merged) memory section(s). In an ideal world, memory listeners would be able to deal with that atomically, like KVM nowadays does. However, (a) supporting this for other memory listeners (vhost-user, vfio) is fairly hard: temporary removal can result in all kinds of issues on concurrent access to guest memory; and (b) this handling is undesired, because temporarily removing+readding can consume quite some time on bigger memslots and is not efficient (e.g., vfio unpinning and repinning pages ...). Let's allow for marking a memory region unmergeable, such that we can atomically (un)map aliases to the same memory region, similar to (un)mapping individual DIMMs. Similarly, teach vhost code to not redo what flatview core stopped doing: don't merge such sections. Merging in vhost code is really only relevant for handling random holes in boot memory where; without this merging, the vhost-user backend wouldn't be able to mmap() some boot memory backed on hugetlb. We'll use this for virtio-mem next. Message-ID: <20230926185738.277351-18-david@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Michael S.

2023-10-12memory: Clarify mapping requirements for RamDiscardManagerDavid Hildenbrand1-2/+2
We really only care about the RAM memory region not being mapped into an address space yet as long as we're still setting up the RamDiscardManager. Once mapped into an address space, memory notifiers would get notified about such a region and any attempts to modify the RamDiscardManager would be wrong. While "mapped into an address space" is easy to check for RAM regions that are mapped directly (following the ->container links), it's harder to check when such regions are mapped indirectly via aliases. For now, we can only detect that a region is mapped through an alias (->mapped_via_alias), but we don't have a handle on these aliases to follow all their ->container links to test if they are eventually mapped into an address space. So relax the assertion in memory_region_set_ram_discard_manager(), remove the check in memory_region_get_ram_discard_manager() and clarify the doc.

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.
