* | hw/arm: Deprecate various old Arm machine typesPeter Maydell2024-03-111-0/+15

After some consultation with the Linux kernel developers, we are going to deprecate: All PXA2xx machines: akita Sharp SL-C1000 (Akita) PDA (PXA270) borzoi Sharp SL-C3100 (Borzoi) PDA (PXA270) connex Gumstix Connex (PXA255) mainstone Mainstone II (PXA27x) spitz Sharp SL-C3000 (Spitz) PDA (PXA270) terrier Sharp SL-C3200 (Terrier) PDA (PXA270) tosa Sharp SL-6000 (Tosa) PDA (PXA255) verdex Gumstix Verdex Pro XL6P COMs (PXA270) z2 Zipit Z2 (PXA27x) All OMAP2 machines: n800 Nokia N800 tablet aka. RX-34 (OMAP2420) n810 Nokia N810 tablet aka. RX-44 (OMAP2420) One of the OMAP1 machines: cheetah Palm Tungsten|E aka. Cheetah PDA (OMAP310) Rationale: * for QEMU dropping individual machines is much less beneficial than if we can drop support for an entire SoC * the OMAP2 QEMU code in particular is large, old and unmaintained, and none of the OMAP2 kernel maintainers said they were using QEMU in any of their testing/development * although there is a setup that is booting test kernels on some of the PXA2xx machines, nobody seemed to be using them as part of their active kernel development and my impression from the email thread is that PXA is the closest of all these SoC families to being dropped from the kernel soon * nobody said they were using cheetah, so it's entirely untested and quite probably broken * on the other hand the OMAP1 sx1 model does seem to be being used as part of kernel development, and there was interest in keeping collie around In particular, the mainstone, tosa and z2 machine types have already been dropped from Linux. Mark all these machine types as deprecated.

* hw/core/machine-smp: Deprecate unsupported "parameter=1" SMP configurationsZhao Liu2024-03-091-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, it was allowed for users to specify the unsupported topology parameter as "1". For example, x86 PC machine doesn't support drawer/book/cluster topology levels, but user could specify "-smp drawers=1,books=1,clusters=1". This is meaningless and confusing, so that the support for this kind of configurations is marked deprecated since 9.0. And report warning message for such case like: qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid): Unsupported clusters parameter mustn't be specified as 1 qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid): Unsupported books parameter mustn't be specified as 1 qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid): Unsupported drawers parameter mustn't be specified as 1 Users have to ensure that all the topology members described with -smp are supported by the target machine.

| | | | | | | | | | | | | | | | This option controls the host page size. From the mis-usage in our own testsuite, this is easily confused with guest page size. The only thing that occurs when changing the host page size is that stuff breaks, because one cannot actually change the host page size. Therefore reject all but the no-op setting as part of the deprecation process.

* docs/about: Mark the old pc-i440fx-2.0 - 2.3 machine types as deprecatedThomas Huth2023-10-271-0/+8
| | | | | | | | | | | | | | | | As we've seen in the past, it's useful for deprecating old machine types to finally be able to get of legacy code or do other clean-ups (see e.g. commit ea985d235b868047 that was used to drop the PCI code in the 128k bios binaries to free some precious space in those binaries). So let's continue deprecating the oldest pc machine types. QEMU 2.3 has been released 8 years ago, so that's plenty of time since such machine types have been used by default, thus deprecating pc-i440fx-2.0 up to pc-i440fx-2.3 should be fine nowadays.

For example there is a patch for a CVE-worthy bug posted more than half a year ago [4] which has never been merged. Thus let's mark it as deprecated and finally remove it unless somebody steps up and improves the code quality and adds proper regression tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At this moment there are eleven CPU extension properties that starts with capital 'Z': Zifencei, Zicsr, Zihintntl, Zihintpause, Zawrs, Zfa, Zfh, Zfhmin, Zve32f, Zve64f and Zve64d. All other extensions are named with lower-case letters. We want all properties to be named with lower-case letters since it's consistent with the riscv-isa string that we create in the FDT. Having these 11 properties to be exceptions can be confusing. Deprecate all of them. Create their lower-case counterpart to be used as maintained CPU properties. When trying to use any deprecated property a warning message will be displayed, recommending users to switch to the lower-case variant: ./build/qemu-system-riscv64 -M virt -cpu rv64,Zifencei=true --nographic qemu-system-riscv64: warning: CPU property 'Zifencei' is deprecated. Please use 'zifencei' instead This will give users some time to change their scripts before we remove the capital 'Z' properties entirely.

* | target/riscv: deprecate the 'any' CPU typeDaniel Henrique Barboza2023-10-121-0/+12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'any' CPU type was introduced in commit dc5bd18fa5725 ("RISC-V CPU Core Definition"), being around since the beginning. It's not an easy CPU to use: it's undocumented and its name doesn't tell users much about what the CPU is supposed to bring. 'git log' doesn't help us either in knowing what was the original design of this CPU type. The closest we have is a comment from Alistair [1] where he recalls from memory that the 'any' CPU is supposed to behave like the newly added 'max' CPU. He also suggested that the 'any' CPU should be removed. The default CPUs are rv32 and rv64, so removing the 'any' CPU will have impact only on users that might have a script that uses '-cpu any'. And those users are better off using the default CPUs or the new 'max' CPU. We would love to just remove the code and be done with it, but one does not simply remove a feature in QEMU. We'll put the CPU in quarantine first, letting users know that we have the intent of removing it in the future.

However, there is still a need for simple configuration of the audio backend in the desktop case; therefore, if no audiodev is passed to audio_init(), go through a bunch of simple Audiodev* structures and pick the first that can be initialized successfully. The only QEMU_AUDIO_* option that is left in, waiting for a better idea, is QEMU_AUDIO_DRV=none which is used by qtest. Remove all the parsing code, including the concept of "can_be_default" audio drivers: now that audio_prio_list[] is only used in a single place, wav can be excluded directly in that function.

Per the latest HAXM release (v7.8 [*]), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. It became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code.

| | | | | | | | | | | | | | | | | | | | In early 2021 (see commit 2ad784339e "docs: update README to use GitLab repo URLs") almost all of the code base was converted to point to GitLab instead of git.qemu.org. During 2023, git.qemu.org switched from a git mirror to a http redirect to GitLab (see [1]). Update the LICENSE URL to match its previous content, displaying the file raw content similarly to gitweb 'blob_plain' format ([2]).

* migration: skipped field is really obsolete.Juan Quintela2023-07-261-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Has return zero for more than 10 years. Specifically we introduced the field in 1.5.0 commit f1c72795af573b24a7da5eb52375c9aba8a37972 Author: Peter Lieven <pl@kamp.de> Date: Tue Mar 26 10:58:37 2013 +0100 migration: do not sent zero pages in bulk stage during bulk stage of ram migration if a page is a zero page do not send it at all. the memory at the destination reads as zero anyway. even if there is an madvise with QEMU_MADV_DONTNEED at the target upon receipt of a zero page I have observed that the target starts swapping if the memory is overcommitted. it seems that the pages are dropped asynchronously. this patch also updates QMP to return the number of skipped pages in MigrationStats. but removed its usage in 1.5.3 commit 9ef051e5536b6368a1076046ec6c4ec4ac12b5c6 Author: Peter Lieven <pl@kamp.de> Date: Mon Jun 10 12:14:19 2013 +0200 Revert "migration: do not sent zero pages in bulk stage" Not sending zero pages breaks migration if a page is zero at the source but not at the destination. This can e.g. happen if different BIOS versions are used at source and destination. It has also been reported that migration on pseries is completely broken with this patch. This effectively reverts commit f1c72795af573b24a7da5eb52375c9aba8a37972. Reviewed-by: Daniel P.
