2024-05-22i386: Support module_id in X86CPUTopoIDsZhao Liu
Add module_id member in X86CPUTopoIDs. module_id can be parsed from APIC ID, so also update APIC ID parsing rule to support module level. With this support, the conversions with module level between X86CPUTopoIDs, X86CPUTopoInfo and APIC ID are completed. module_id can be also generated from cpu topology, and before i386 supports "modules" in smp, the default "modules per die" (modules * clusters) is only 1, thus the module_id generated in this way is 0, so that it will not conflict with the module_id generated by APIC ID.

2024-05-22i386: Expose module level in CPUID[0x1F]Zhao Liu
Linux kernel (from v6.4, with commit edc0a2b595765 ("x86/topology: Fix erroneous smp_num_siblings on Intel Hybrid platforms") is able to handle platforms with Module level enumerated via CPUID.1F. Expose the module level in CPUID[0x1F] if the machine has more than 1 modules.

2024-05-22i386: Support modules_per_die in X86CPUTopoInfoZhao Liu
Support module level in i386 cpu topology structure "X86CPUTopoInfo". Since x86 does not yet support the "modules" parameter in "-smp", X86CPUTopoInfo.modules_per_die is currently always 1. Therefore, the module level width in APIC ID, which can be calculated by "apicid_bitwidth_for_count(topo_info->modules_per_die)", is always 0 for now, so we can directly add APIC ID related helpers to support module level parsing. In addition, update topology structure in test-x86-topo.c.

2024-05-22i386/cpu: Introduce bitmap to cache available CPU topology levelsZhao Liu
Currently, QEMU checks the specify number of topology domains to detect if there's extended topology levels (e.g., checking nr_dies). With this bitmap, the extended CPU topology (the levels other than SMT, core and package) could be easier to detect without touching the topology details. This is also in preparation for the follow-up to decouple CPUID[0x1F] subleaf with specific topology level.

2024-05-22hw/i386/pc_sysfw: Alias rather than copy isa-bios regionBernhard Beschow
In the -bios case the "isa-bios" memory region is an alias to the BIOS mapped to the top of the 4G memory boundary. Do the same in the -pflash case, but only for new machine versions for migration compatibility. This establishes common behavior and makes pflash commands work in the "isa-bios" region which some real-world legacy bioses rely on. Note that in the sev_enabled() case, the "isa-bios" memory region in the -pflash case will now also point to encrypted memory, just like it already does in the -bios case. When running `info mtree` before and after this commit with `qemu-system-x86_64 -S -drive \ if=pflash,format=raw,readonly=on,file=/usr/share/qemu/bios-256k.bin` and running `diff -u before.mtree after.mtree` results in the following changes in the memory tree: --- before.mtree +++ after.mtree @@ -71,7 +71,7 @@ 0000000000000000-ffffffffffffffff (prio -1, i/o): pci 00000000000a0000-00000000000bffff (prio 1, i/o): vga-lowmem 00000000000c0000-00000000000dffff (prio 1, rom): pc.rom - 00000000000e0000-00000000000fffff (prio 1, rom): isa-bios + 00000000000e0000-00000000000fffff (prio 1, romd): alias isa-bios @system.flash0 0000000000020000-000000000003ffff 00000000000a0000-00000000000bffff (prio 1, i/o): alias smram-region @pci 00000000000a0000-00000000000bffff 00000000000c0000-00000000000c3fff (prio 1, i/o): alias pam-pci @pci 00000000000c0000-00000000000c3fff 00000000000c4000-00000000000c7fff (prio 1, i/o): alias pam-pci @pci 00000000000c4000-00000000000c7fff @@ -108,7 +108,7 @@ 0000000000000000-ffffffffffffffff (prio -1, i/o): pci 00000000000a0000-00000000000bffff (prio 1, i/o): vga-lowmem 00000000000c0000-00000000000dffff (prio 1, rom): pc.rom - 00000000000e0000-00000000000fffff (prio 1, rom): isa-bios + 00000000000e0000-00000000000fffff (prio 1, romd): alias isa-bios @system.flash0 0000000000020000-000000000003ffff 00000000000a0000-00000000000bffff (prio 1, i/o): alias smram-region @pci 00000000000a0000-00000000000bffff 00000000000c0000-00000000000c3fff (prio 1, i/o): alias pam-pci @pci 00000000000c0000-00000000000c3fff 00000000000c4000-00000000000c7fff (prio 1, i/o): alias pam-pci @pci 00000000000c4000-00000000000c7fff @@ -131,11 +131,14 @@ memory-region: pc.ram 0000000000000000-0000000007ffffff (prio 0, ram): pc.ram +memory-region: system.flash0 + 00000000fffc0000-00000000ffffffff (prio 0, romd): system.flash0 + memory-region: pci 0000000000000000-ffffffffffffffff (prio -1, i/o): pci 00000000000a0000-00000000000bffff (prio 1, i/o): vga-lowmem 00000000000c0000-00000000000dffff (prio 1, rom): pc.rom - 00000000000e0000-00000000000fffff (prio 1, rom): isa-bios + 00000000000e0000-00000000000fffff (prio 1, romd): alias isa-bios @system.flash0 0000000000020000-000000000003ffff memory-region: smram 00000000000a0000-00000000000bffff (prio 0, ram): alias smram-low @pc.ram 00000000000a0000-00000000000bffff Note that in both cases the "system" memory region contains the entry 00000000fffc0000-00000000ffffffff (prio 0, romd): system.flash0 but the "system.flash0" memory region only appears standalone when "isa-bios" is an alias.

While there are other methods that could be used to replace TARGET_PAGE_MASK, the function is not really required outside the context of target-specific translation. This makes the header usable by target independent code. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2024-05-14ui/console: Use qemu_dmabuf_new() and free() helpers insteadDongwon Kim
This commit introduces utility functions for the creation and deallocation of QemuDmaBuf instances. Additionally, it updates all relevant sections of the codebase to utilize these new utility functions. v7: remove prefix, "dpy_gl_" from all helpers qemu_dmabuf_free() returns without doing anything if input is null (Daniel P. Berrangé <berrange@redhat.com>) call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free() (Daniel P. Berrangé <berrange@redhat.com>) v8: Introduction of helpers was removed as those were already added by the previous commit v9: set dmabuf->allow_fences to 'true' when dmabuf is created in virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c removed unnecessary spaces were accidently added in the patch, 'ui/console: Use qemu_dmabuf_new() a...' v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be done in qemu_dmabuf_free anyway. (Daniel P. Berrangé <berrange@redhat.com>) v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't do it. --- 'dmabuf' is now allocated space so it should be freed at the end of dbus_scanout_texture v13: --- Immediately free dmabuf after it is released to prevent possible leaking of the ptr (Marc-André Lureau <marcandre.lureau@redhat.com>) --- Use g_autoptr macro to define *dmabuf for auto clean up instead of calling qemu_dmabuf_free (Marc-André Lureau <marcandre.lureau@redhat.com>) v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer as it was done because of some misunderstanding (v13). --- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL to prevent freed dmabuf to be accessed again in case if(fd==-1)break; happens (before new dmabuf is allocated). Otherwise, it would cause invalid memory access when the same function is executed. Also NULL check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).

2024-05-14ui/console: new dmabuf.h and dmabuf.c for QemuDmaBuf struct and helpersDongwon Kim
New header and source files are added for containing QemuDmaBuf struct definition and newly introduced helpers for creating/freeing the struct and accessing its data. v10: Change the license type for both dmabuf.h and dmabuf.c from MIT to GPL to be in line with QEMU's default license v11: -- Added new helpers, qemu_dmabuf_close for closing dmabuf->fd, qemu_dmabuf_dup_fd for duplicating dmabuf->fd (Daniel P. Berrangé <berrange@redhat.com>) -- Let qemu_dmabuf_fee to call qemu_dmabuf_close before freeing the struct to make sure fd is closed. (Daniel P. Berrangé <berrange@redhat.com>) v12: Not closing fd in qemu_dmabuf_free because there are cases fd should still be available even after the struct is destroyed (e.g. virtio-gpu: res->dmabuf_fd).

2024-05-14util/uri: Remove the old URI parsing codeThomas Huth
Now that we switched all consumers of the URI code to use the URI parsing functions from glib instead, we can remove our internal URI parsing code since it is not used anymore.

2024-05-14Bump minimum glib version to v2.66Thomas Huth
Now that we dropped support for CentOS 8 and Ubuntu 20.04, we can look into bumping the glib version to a new minimum for further clean-ups. According to repology.org, available versions are: CentOS Stream 9: 2.66.7 Debian 11: 2.66.8 Fedora 38: 2.74.1 Freebsd: 2.78.4 Homebrew: 2.80.0 Openbsd: 2.78.4 OpenSuse leap 15.5: 2.70.5 pkgsrc_current: 2.78.4 Ubuntu 22.04: 2.72.1 Thus it should be safe to bump the minimum glib version to 2.66 now. Version 2.66 comes with new functions for URI parsing which will allow further clean-ups in the following patches. Reviewed-by: Daniel P.

2024-05-10hw/i386: move rtc-reset-reinjection command out of hw/rtcPaolo Bonzini
The rtc-reset-reinjection QMP command is specific to x86, other boards do not have the ACK tracking functionality that is needed for RTC interrupt reinjection. Therefore the QMP command is only included in x86, but qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c and requires tracking of all created RTC devices. Move the implementation to hw/i386, so that 1) it is available even if no RTC device exist 2) the only RTC that exists is easily found in x86ms->rtc.
