2021-02-15bswap.h: Remove unused float-access functionsPeter Maydell
The float-access functions stfl_*, stfq*, ldfl* and ldfq* are now unused; remove them. (Accesses to float64 and float32 types can be made with the ldl/stl/ldq/stq functions, as float64 and float32 are guaranteed to be typedefs for normal integer types.)

2021-02-10docs: fix Parallels Image "dirty bitmap" sectionDenis V. Lunev
Original specification says that l1 table size if 64 * l1_size, which is obviously wrong. The size of the l1 entry is 64 _bits_, not bytes. Thus 64 is to be replaces with 8 as specification says about bytes. There is also minor tweak, field name is renamed from l1 to l1_table, which matches with the later text. Signed-off-by: Denis V.

2021-02-08meson: accept either shared or static libraries if --disable-staticPaolo Bonzini
Meson's "static" argument to cc.find_library is a tri-state. By default Meson *prefers* a shared library, which basically means using -l to look for it; instead, "static: false" *requires* a shared library. Of course, "static: true" requires a static library, which is all good for --enable-static builds. For --disable-static, "static: false" is rarely desirable; it does not match what the configure script used to do and the test is more complex (and harder to debug if it fails, which was reported by Peter Lieven for librbd).

2021-02-08s390: Recognize confidential-guest-support optionDavid Gibson
At least some s390 cpu models support "Protected Virtualization" (PV), a mechanism to protect guests from eavesdropping by a compromised hypervisor. This is similar in function to other mechanisms like AMD's SEV and POWER's PEF, which are controlled by the "confidential-guest-support" machine option. s390 is a slightly special case, because we already supported PV, simply by using a CPU model with the required feature (S390_FEAT_UNPACK). To integrate this with the option used by other platforms, we implement the following compromise: - When the confidential-guest-support option is set, s390 will recognize it, verify that the CPU can support PV (failing if not) and set virtio default options necessary for encrypted or protected guests, as on other platforms. i.e. if confidential-guest-support is set, we will either create a guest capable of entering PV mode, or fail outright. - If confidential-guest-support is not set, guests might still be able to enter PV mode, if the CPU has the right model. This may be a little surprising, but shouldn't actually be harmful. To start a guest supporting Protected Virtualization using the new option use the command line arguments: -object s390-pv-guest,id=pv0 -machine confidential-guest-support=pv0 Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Tested-by: Christian Borntraeger <borntraeger@de.ibm.com> Reviewed-by: Christian Borntraeger <borntraeger@de.ibm.com>
2021-02-08spapr: Add PEF based confidential guest supportDavid Gibson
Some upcoming POWER machines have a system called PEF (Protected Execution Facility) which uses a small ultravisor to allow guests to run in a way that they can't be eavesdropped by the hypervisor. The effect is roughly similar to AMD SEV, although the mechanisms are quite different. Most of the work of this is done between the guest, KVM and the ultravisor, with little need for involvement by qemu. However qemu does need to tell KVM to allow secure VMs. Because the availability of secure mode is a guest visible difference which depends on having the right hardware and firmware, we don't enable this by default. In order to run a secure guest you need to create a "pef-guest" object and set the confidential-guest-support property to point to it. Note that this just *allows* secure guests, the architecture of PEF is such that the guest still needs to talk to the ultravisor to enter secure mode. Qemu has no direct way of knowing if the guest is in secure mode, and certainly can't know until well after machine creation time. To start a PEF-capable guest, use the command line options: -object pef-guest,id=pef0 -machine confidential-guest-support=pef0 Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Greg Kurz <groug@kaod.org>

The distinction between short life and long life Linux distributions turned out to be redundant. They can both be covered in a simple way by noting support will target the current release, and the previous release for a period of two years or until its EOL. This rule can also apply to the other UNIX based distros, leaving only Windows needing a different set of rules. This also clarifies that Debian LTS is out of scope, because the LTS support is provided by a separate group from the main Debian maintainer team.

2021-01-29os: deprecate the -enable-fips option and QEMU's FIPS enforcementDaniel P. Berrangé
The -enable-fips option was added a long time ago to prevent the use of single DES when VNC when FIPS mode is enabled. It should never have been added, because apps are supposed to unconditionally honour FIPS mode based on the '/proc/sys/crypto/fips_enabled' file contents. In addition there is more to achieving FIPS compliance than merely blocking use of certain algorithms. Those algorithms which are used need to perform self-tests at runtime. QEMU's built-in cryptography provider has no support for self-tests, and neither does the nettle library. If QEMU is required to be used in a FIPS enabled host, then it must be built with the libgcrypt library enabled, which will unconditionally enforce FIPS compliance in any algorithm usage.

2021-01-27iotests: add findtests.pyVladimir Sementsov-Ogievskiy
Add python script with new logic of searching for tests: Current ./check behavior: - tests are named [0-9][0-9][0-9] - tests must be registered in group file (even if test doesn't belong to any group, like 142) Behavior of findtests.py: - group file is dropped - tests are all files in tests/ subdirectory (except for .out files), so it's not needed more to "register the test", just create it with appropriate name in tests/ subdirectory. Old names like [0-9][0-9][0-9] (in root iotests directory) are supported too, but not recommended for new tests - groups are parsed from '# group: ' line inside test files - optional file group.local may be used to define some additional groups for downstreams - 'disabled' group is used to temporary disable tests. So instead of commenting tests in old 'group' file you now can add them to disabled group with help of 'group.local' file - selecting test ranges like 5-15 are not supported more (to support restarting failed ./check command from the middle of the process, new argument is added: --start-from) Benefits: - no rebase conflicts in group file on patch porting from branch to branch - no conflicts in upstream, when different series want to occupy same test number - meaningful names for test files For example, with digital number, when some person wants to add some test about block-stream, he most probably will just create a new test. But if there would be test-block-stream test already, he will at first look at it and may be just add a test-case into it. And anyway meaningful names are better. This commit doesn't update check behavior (which will be done in further commit), still, the documentation changed like new behavior is already here. Let's live with this small inconsistency for the following few commits, until final change.

2021-01-23qemu-option: warn for short-form boolean optionsPaolo Bonzini
Options such as "server" or "nowait", that are commonly found in -chardev, are sugar for "server=on" and "wait=off". This is quite surprising and also does not have any notion of typing attached. It is even possible to do "-device e1000,noid" and get a device with "id=off". Deprecate it and print a warning when it is encountered. In general, this short form for boolean options only seems to be in wide use for -chardev and -spice. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-01-23hmp: remove "change vnc TARGET" commandPaolo Bonzini
The HMP command \"change vnc TARGET\" is messy: - it takes an ugly shortcut to determine if the option has an "id", with incorrect results if "id=" is not preceded by an unescaped comma. - it deletes the existing QemuOpts and does not try to rollback if the parsing fails (which is not causing problems, but only due to how VNC options are parsed) - because it uses the same parsing function as "-vnc", it forces the latter to not support "-vnc help". On top of this, it uses a deprecated QMP command, thus getting in the way of removing the QMP command. Since the usecase for the command is not clear, just remove it and send "change vnc password" directly to the QMP "change-vnc-password" command.

2021-01-19docs: Build and install all the docs in a single manualPeter Maydell
When we first converted our documentation to Sphinx, we split it into multiple manuals (system, interop, tools, etc), which are all built separately. The primary driver for this was wanting to be able to avoid shipping the 'devel' manual to end-users. However, this is working against the grain of the way Sphinx wants to be used and causes some annoyances: * Cross-references between documents become much harder or possibly impossible * There is no single index to the whole documentation * Within one manual there's no links or table-of-contents info that lets you easily navigate to the others * The devel manual doesn't get published on the QEMU website (it would be nice to able to refer to it there) Merely hiding our developer documentation from end users seems like it's not enough benefit for these costs. Combine all the documentation into a single manual (the same way that the readthedocs site builds it) and install the whole thing. The previous manual divisions remain as the new top level sections in the manual. * The per-manual conf.py files are no longer needed * The man_pages[] specifications previously in each per-manual conf.py move to the top level conf.py * docs/meson.build logic is simplified as we now only need to run Sphinx once for the HTML and then once for the manpages5B * The old index.html.in that produced the top-level page with links to each manual is no longer needed Unfortunately this means that we now have to build the HTML documentation into docs/manual in the build tree rather than directly into docs/; otherwise it is too awkward to ensure we install only the built manual and not also the dependency info, stamp file, etc. The manual still ends up in the same place in the final installed directory, but anybody who was consulting documentation from within the build tree will have to adjust where they're looking.

Add two boolean properties that allows the feature to be turned off, on with the architected algorithm, or on with an implementation defined algorithm.

2021-01-12hw/misc: Add a PWM module for NPCM7XXHao Wu
The PWM module is part of NPCM7XX module. Each NPCM7XX module has two identical PWM modules. Each module contains 4 PWM entries. Each PWM has two outputs: frequency and duty_cycle. Both are computed using inputs from software side. This module does not model detail pulse signals since it is expensive. It also does not model interrupts and watchdogs that are dependant on the detail models. The interfaces for these are left in the module so that anyone in need for these functionalities can implement on their own. The user can read the duty cycle and frequency using qom-get command.
