2022-04-06hyperv: Add support to process syndbg commandsJon Doron1-0/+15
SynDbg commands can come from two different flows: 1. Hypercalls, in this mode the data being sent is fully encapsulated network packets. 2. SynDbg specific MSRs, in this mode only the data that needs to be transfered is passed.

2022-03-04qsd: Add --daemonizeHanna Reitz1-0/+7
To implement this, we reuse the existing daemonizing functions from the system emulator, which mainly do the following: - Fork off a child process, and set up a pipe between parent and child - The parent process waits until the child sends a status byte over the pipe (0 means that the child was set up successfully; anything else (including errors or EOF) means that the child was not set up successfully), and then exits with an appropriate exit status - The child process enters a new session (forking off again), changes the umask, and will ignore terminal signals from then on - Once set-up is complete, the child will chdir to /, redirect all standard I/O streams to /dev/null, and tell the parent that set-up has been completed successfully In contrast to qemu-nbd's --fork implementation, during the set up phase, error messages are not piped through the parent process. qemu-nbd mainly does this to detect errors, though (while os_daemonize() has the child explicitly signal success after set up); because we do not redirect stderr after forking, error messages continue to appear on whatever the parent's stderr was (until set up is complete).

2022-03-02target/arm: Implement FEAT_LPA2Richard Henderson1-0/+1
This feature widens physical addresses (and intermediate physical addresses for 2-stage translation) from 48 to 52 bits, when using 4k or 16k pages. This introduces the DS bit to TCR_ELx, which is RES0 unless the page size is enabled and supports LPA2, resulting in the effective value of DS for a given table walk. The DS bit changes the format of the page table descriptor slightly, moving the PS field out to TCR so that all pages have the same sharability and repurposing those bits of the page table descriptor for the highest bits of the output address. Do not yet enable FEAT_LPA2; we need extra plumbing to avoid tickling an old kernel bug.

2022-03-02target/arm: Implement FEAT_LVARichard Henderson1-0/+1
This feature is relatively small, as it applies only to 64k pages and thus requires no additional changes to the table descriptor walking algorithm, only a change to the minimum TSZ (which is the inverse of the maximum virtual address space size). Note that this feature widens VBAR_ELx, but we already treat the register as being 64 bits wide.

2022-03-02migration: Remove load_state_old and minimum_version_id_oldPeter Maydell1-9/+3
There are no longer any VMStateDescription structs in the tree which use the load_state_old support for custom handling of incoming migration from very old QEMU. Remove the mechanism entirely. This includes removing one stray useless setting of minimum_version_id_old in a VMStateDescription with no load_state_old function, which crept in after the global weeding-out of them in commit 17e313406126.

2022-02-21Kconfig: Add I2C_DEVICES device groupPeter Maydell1-2/+6
Currently there is no way for a board model's Kconfig stanza to say "I have an i2c bus which the user can plug an i2c device into, build all the free-standing i2c devices". The Kconfig mechanism for this is the "device group". Add an I2C_DEVICES group along the same lines as the existing PCI_DEVICES. Simple free-standing i2c devices which a user might plausibly want to be able to plug in on the QEMU commandline should have default y if I2C_DEVICES and board models which have an i2c bus that is user-accessible should use imply I2C_DEVICES to cause those pluggable devices to be built. In this commit we mark only a fairly conservative set of i2c devices as belonging to the I2C_DEVICES group: the simple sensors and RTCs (not including PMBus devices or devices which need GPIO lines to be connected).

2022-02-16docs: expand firmware descriptor to allow flash without NVRAMDaniel P. Berrangé1-8/+46
The current firmware descriptor schema for flash requires that both the executable to NVRAM template paths be provided. This is fine for the most common usage of EDK2 builds in virtualization where the separate _CODE and _VARS files are provided. With confidential computing technology like AMD SEV, persistent storage of variables may be completely disabled because the firmware requires a known clean state on every cold boot. There is no way to express this in the firmware descriptor today. Even with regular EDK2 builds it is possible to create a firmware that has both executable code and variable persistence in a single file. This hasn't been commonly used, since it would mean every guest bootup would need to clone the full firmware file, leading to redundant duplicate storage of the code portion. In some scenarios this may not matter and might even be beneficial. For example if a public cloud allows users to bring their own firmware, such that the user can pre-enroll their own secure boot keys, you're going to have this copied on disk for each tenant already. At this point the it can be simpler to just deal with a single file rather than split builds. The firmware descriptor ought to be able to express this combined firmware model too. This all points towards expanding the schema for flash with a 'mode' concept: - "split" - the current implicit behaviour with separate files for code and variables. - "combined" - the alternate behaviour where a single file contains both code and variables. - "stateless" - the confidential computing use case where storage of variables is completely disable, leaving only the code.

2022-02-01qemu-img: Unify [-b [-F]] documentationHanna Reitz1-1/+1
qemu-img convert documents the backing file and backing format options as follows: [-B backing_file [-F backing_fmt]] whereas qemu-img create has this: [-b backing_file] [-F backing_fmt] That is, for convert, we document that -F cannot be given without -B, while for create, way say that they are independent. Indeed, it is technically possible to give -F without -b, because it is left to the block driver to decide whether this is an error or not, so sometimes it is: $ qemu-img create -f qed -F qed test.qed 64M Formatting 'test.qed', fmt=qed size=67108864 backing_fmt=qed [...] And sometimes it is not: $ qemu-img create -f qcow2 -F qcow2 test.qcow2 64M Formatting 'test.qcow2', fmt=qcow2 cluster_size=65536 [...] qemu-img: test.qcow2: Backing format cannot be used without backing file Generally, it does not make much sense, though, and users should only give -F with -b, so document it that way, as we have already done for qemu-img convert (commit 1899bf47375ad40555dcdff12ba49b4b8b82df38).
