New pylint warning. I could silence it, but this is the only occurrence in the entire tree, including everything in iotests/ and python/. Easier to just change this one instance.

Currently the only difference between smp_parse and pc_smp_parse is the support of dies parameter and the related error reporting. With some arch compat variables like "bool dies_supported", we can make smp_parse generic enough for all arches and the PC specific one can be removed. Making smp_parse() generic enough can reduce code duplication and ease the code maintenance, and also allows extending the topology with more arch specific members (e.g., clusters) in the future.

2021-10-01machine: Prefer cores over sockets in smp parsing since 6.2Yanan Wang9-19/+60
In the real SMP hardware topology world, it's much more likely that we have high cores-per-socket counts and few sockets totally. While the current preference of sockets over cores in smp parsing results in a virtual cpu topology with low cores-per-sockets counts and a large number of sockets, which is just contrary to the real world. Given that it is better to make the virtual cpu topology be more reflective of the real world and also for the sake of compatibility, we start to prefer cores over sockets over threads in smp parsing since machine type 6.2 for different arches. In this patch, a boolean "smp_prefer_sockets" is added, and we only enable the old preference on older machines and enable the new one since type 6.2 for all arches by using the machine compat mechanism.

2021-10-01qtest/numa-test: Use detailed -smp CLIs in test_def_cpu_splitYanan Wang1-1/+2
Since commit 80d7835749 (qemu-options: rewrite help for -smp options), the preference of sockets/cores in -smp parsing is considered liable to change, and actually we are going to change it in a coming commit. So it'll be more stable to use detailed -smp CLIs in the testcases that have strong dependency on the parsing results. Currently, test_def_cpu_split use "-smp 8" and will get 8 CPU sockets based on current parsing rule. But if we change to prefer cores over sockets we will get one CPU socket with 8 cores, and this testcase will not get expected numa set by default on x86_64 (Ok on aarch64). So now explicitly use "-smp 8,sockets=8" to avoid affect from parsing logic change.

2021-10-01machine: Improve the error reporting of smp parsingYanan Wang2-27/+19
We have two requirements for a valid SMP configuration: the product of "sockets * cores * threads" must represent all the possible cpus, i.e., max_cpus, and then must include the initially present cpus, i.e., smp_cpus. So we only need to ensure 1) "sockets * cores * threads == maxcpus" at first and then ensure 2) "maxcpus >= cpus". With a reasonable order of the sanity check, we can simplify the error reporting code. When reporting an error message we also report the exact value of each topology member to make users easily see what's going on.

2021-10-01machine: Set the value of cpus to match maxcpus if it's omittedYanan Wang3-29/+40
Currently we directly calculate the omitted cpus based on the given incomplete collection of parameters. This makes some cmdlines like: -smp maxcpus=16 -smp sockets=2,maxcpus=16 -smp sockets=2,dies=2,maxcpus=16 -smp sockets=2,cores=4,maxcpus=16 not work. We should probably set the value of cpus to match maxcpus if it's omitted, which will make above configs start to work. So the calculation logic of cpus/maxcpus after this patch will be: When both maxcpus and cpus are omitted, maxcpus will be calculated from the given parameters and cpus will be set equal to maxcpus. When only one of maxcpus and cpus is given then the omitted one will be set to its counterpart's value. Both maxcpus and cpus may be specified, but maxcpus must be equal to or greater than cpus. Note: change in this patch won't affect any existing working cmdlines but allows more incomplete configs to be valid.

2021-10-01machine: Uniformly use maxcpus to calculate the omitted parametersYanan Wang2-30/+30
We are currently using maxcpus to calculate the omitted sockets but using cpus to calculate the omitted cores/threads. This makes cmdlines like: -smp cpus=8,maxcpus=16 -smp cpus=8,cores=4,maxcpus=16 -smp cpus=8,threads=2,maxcpus=16 work fine but the ones like: -smp cpus=8,sockets=2,maxcpus=16 -smp cpus=8,sockets=2,cores=4,maxcpus=16 -smp cpus=8,sockets=2,threads=2,maxcpus=16 break the sanity check. Since we require for a valid config that the product of "sockets * cores * threads" should equal to the maxcpus, we should uniformly use maxcpus to calculate their omitted values. Also the if-branch of "cpus == 0 || sockets == 0" was split into two branches of "cpus == 0" and "sockets == 0" so that we can clearly read that we are parsing the configuration with a preference on cpus over sockets over cores over threads. Note: change in this patch won't affect any existing working cmdlines but improves consistency and allows more incomplete configs to be valid.

into staging ppc patch queue for 2021-09-30 Here's the next batch of ppc related patches for qemu-6.2. Highlights are: * Fixes for several TCG math instructions from the El Dorado Institute * A number of improvements to the powernv machine type * Support for a new DEVICE_UNPLUG_GUEST_ERROR QAPI event from Daniel Barboza * Support for the new FORM2 PAPR NUMA representation. This allows more specific NUMA distances, as well as asymmetric configurations * Fix for 64-bit decrementer (used on MicroWatt CPUs) * Assorted fixes and cleanups * A number of updates to MAINTAINERS Note that the DEVICE_UNPLUG_GUEST_ERROR stuff includes changes to files outside my normal area, but has suitable Acks. The MAINTAINERS updates are mostly about marking minor platforms unmaintained / orphaned, and moving some pieces away from myself and Greg. As we move onto other projects, we're going to need to drop more of the ppc maintainership, though we're hoping we can avoid too abrupt a change. # gpg: Signature made Thu 30 Sep 2021 06:42:41 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-6.2-20210930: (44 commits) MAINTAINERS: Demote sPAPR from "Supported" to "Maintained" MAINTAINERS: Add information for OpenPIC MAINTAINERS: Remove David & Greg as reviewers/co-maintainers of powernv MAINTAINERS: Orphan obscure ppc platforms MAINTAINERS: Remove David & Greg as reviewers for a number of boards MAINTAINERS: Remove machine specific files from ppc TCG CPUs entry spapr/xive: Fix kvm_xive_source_reset trace event spapr_numa.c: fixes in spapr_numa_FORM2_write_rtas_tables() hw/intc: openpic: Clean up the styles hw/intc: openpic: Drop Raven related codes hw/intc: openpic: Correct the reset value of IPIDR for FSL chipset target/ppc: Fix 64-bit decrementer target/ppc: Convert debug to trace events (decrementer and IRQ) spapr_numa.c: handle auto NUMA node with no distance info spapr_numa.c: FORM2 NUMA affinity support spapr: move FORM1 verifications to post CAS spapr_numa.c: rename numa_assoc_array to FORM1_assoc_array spapr_numa.c: parametrize FORM1 macros spapr_numa.c: scrap 'legacy_numa' concept spapr_numa.c: split FORM1 code into helpers ...

2021-09-30meson_options.txt: Switch the default value for the vnc option to 'auto'Thomas Huth1-1/+1
There is no reason why VNC should always be enabled and not be set to the default value. We already switched the setting in the "configure" script in commit 3a6a1256d4 ("configure: Allow vnc to get disabled with --without-default-features"), so let's do that in meson_options.txt now, too.

2021-09-30target/i386: Fix memory leak in sev_read_file_base64()Peter Maydell1-1/+1
In sev_read_file_base64() we call g_file_get_contents(), which allocates memory for the file contents. We then base64-decode the contents (which allocates another buffer for the decoded data), but forgot to free the memory for the original file data. Use g_autofree to ensure that the file data is freed.

2021-09-30meson: unpack edk2 firmware even if --disable-blobsPaolo Bonzini3-11/+11
The edk2 firmware blobs are needed to run bios-tables-test. Unpack them if any UEFI-enabled target is selected, so that the test can run. This is a bit more than is actually necessary, since bios-tables-test does not run for all UEFI-enabled targets, but it is the easiest way to write this logic.

2021-09-30i386: acpi: Add SGX EPC entry to ACPI tablesSean Christopherson1-0/+22
The ACPI Device entry for SGX EPC is essentially a hack whose primary purpose is to provide software with a way to autoprobe SGX support, e.g. to allow software to implement SGX support as a driver. Details on the individual EPC sections are not enumerated through ACPI tables, i.e. software must enumerate the EPC sections via CPUID. Furthermore, software expects to see only a single EPC Device in the ACPI tables regardless of the number of EPC sections in the system. However, several versions of Windows do rely on the ACPI tables to enumerate the address and size of the EPC. So, regardless of the number of EPC sections exposed to the guest, create exactly *one* EPC device with a _CRS entry that spans the entirety of all EPC sections (which are guaranteed to be contiguous in Qemu). Note, NUMA support for EPC memory is intentionally not considered as enumerating EPC NUMA information is not yet defined for bare metal.
