2022-06-10hw/core/loader: return image sizes as ssize_tJamie Iles
Various loader functions return an int which limits images to 2GB which is fine for things like a BIOS/kernel image, but if we want to be able to load memory images or large ramdisks then any file over 2GB would silently fail to load.

2022-06-09include/hw/ide: Unexport pci_piix3_xen_ide_unplug()Bernhard Beschow
This function was declared in a generic and public header, implemented in a device-specific source file but only used in xen_platform. Given its 'aux' parameter, this function is more xen-specific than piix-specific. Also, the hardcoded magic constants seem to be generic and related to PCIIDEState and IDEBus rather than piix. Therefore, move this function to xen_platform, unexport it, and drop the "piix3" in the function name as well.

2022-06-03ui: Switch "-display sdl" to use the QAPI parserThomas Huth
The "-display sdl" option still uses a hand-crafted parser for its parameters since we didn't want to drag an interface we considered somewhat flawed into the QAPI schema. Since the flaws are gone now, it's time to QAPIfy. This introduces the new "DisplaySDL" QAPI struct that is used to hold the parameters that are unique to the SDL display. The only specific parameter is currently "grab-mod" that is used to specify the required modifier keys to escape from the mouse grabbing mode.

2022-05-26pseries: allow setting stdout-path even on machines with a VGAPaolo Bonzini
-machine graphics=off is the usual way to tell the firmware or the OS that the user wants a serial console. The pseries machine however does not support this, and never adds the stdout-path node to the device tree if a VGA device is provided. This is in addition to the other magic behavior of VGA devices, which is to add a keyboard and mouse to the default USB bus. Split spapr->has_graphics in two variables so that the two behaviors can be separated: the USB devices remains the same, but the stdout-path is added even with "-device VGA -machine graphics=off".

2022-05-19ptimer: Rename PTIMER_POLICY_DEFAULT to PTIMER_POLICY_LEGACYPeter Maydell
The traditional ptimer behaviour includes a collection of weird edge case behaviours. In 2016 we improved the ptimer implementation to fix these and generally make the behaviour more flexible, with ptimers opting in to the new behaviour by passing an appropriate set of policy flags to ptimer_init(). For backwards-compatibility, we defined PTIMER_POLICY_DEFAULT (which sets no flags) to give the old weird behaviour. This turns out to be a poor choice of name, because people writing new devices which use ptimers are misled into thinking that the default is probably a sensible choice of flags, when in fact it is almost always not what you want. Rename PTIMER_POLICY_DEFAULT to PTIMER_POLICY_LEGACY and beef up the comment to more clearly say that new devices should not be using it. The code-change part of this commit was produced by sed -i -e 's/PTIMER_POLICY_DEFAULT/PTIMER_POLICY_LEGACY/g' $(git grep -l PTIMER_POLICY_DEFAULT) with the exception of a test name string change in tests/unit/ptimer-test.c which was added manually.

Make the GICv3 set its number of bits of physical priority from the implementation-specific value provided in the CPU state struct, in the same way we already do for virtual priority bits. Because this would be a migration compatibility break, we provide a property force-8-bit-prio which is enabled for 7.0 and earlier versioned board models to retain the legacy "always use 8 bits" behaviour.

2022-05-19hw/intc/arm_gicv3: Support configurable number of physical priority bitsPeter Maydell
The GICv3 code has always supported a configurable number of virtual priority and preemption bits, but our implementation currently hardcodes the number of physical priority bits at 8. This is not what most hardware implementations provide; for instance the Cortex-A53 provides only 5 bits of physical priority. Make the number of physical priority/preemption bits driven by fields in the GICv3CPUState, the way that we already do for virtual priority/preemption bits. We set cs->pribits to 8, so there is no behavioural change in this commit. A following commit will add the machinery for CPUs to set this to the correct value for their implementation. Note that changing the number of priority bits would be a migration compatibility break, because the semantics of the icc_apr[][] array changes.

2022-05-18docs/about: Update the support statement for WindowsThomas Huth
Our support statement for Windows currently talks about "Vista / Server 2008" - which is related to the API of Windows, and this is not easy to understand for the non-technical users. Additionally, glib sets the _WIN32_WINNT macro to 0x0601 already, which indicates the Windows 7 API, so QEMU effectively depends on the Windows 7 API, too. Thus let's bump the _WIN32_WINNT setting in QEMU to the same level as glib uses and adjust our support statement in the documentation to something similar that we're using for Linux and the *BSD systems (i.e. only the two most recent versions), which should hopefully be easier to understand for the users now. And since we're nowadays also compile-testing QEMU with MSYS2 on Windows itself, I think we could mention this build environment here, too.

2022-05-16QIOChannelSocket: Implement io_writev zero copy flag & io_flush for CONFIG_LINUXLeonardo Bras
For CONFIG_LINUX, implement the new zero copy flag and the optional callback io_flush on QIOChannelSocket, but enables it only when MSG_ZEROCOPY feature is available in the host kernel, which is checked on qio_channel_socket_connect_sync() qio_channel_socket_flush() was implemented by counting how many times sendmsg(...,MSG_ZEROCOPY) was successfully called, and then reading the socket's error queue, in order to find how many of them finished sending. Flush will loop until those counters are the same, or until some error occurs. Notes on using writev() with QIO_CHANNEL_WRITE_FLAG_ZERO_COPY: 1: Buffer - As MSG_ZEROCOPY tells the kernel to use the same user buffer to avoid copying, some caution is necessary to avoid overwriting any buffer before it's sent. If something like this happen, a newer version of the buffer may be sent instead. - If this is a problem, it's recommended to call qio_channel_flush() before freeing or re-using the buffer. 2: Locked memory - When using MSG_ZERCOCOPY, the buffer memory will be locked after queued, and unlocked after it's sent. - Depending on the size of each buffer, and how often it's sent, it may require a larger amount of locked memory than usually available to non-root user. - If the required amount of locked memory is not available, writev_zero_copy will return an error, which can abort an operation like migration, - Because of this, when an user code wants to add zero copy as a feature, it requires a mechanism to disable it, so it can still be accessible to less privileged users.

2022-05-16QIOChannel: Add flags on io_writev and introduce io_flush callbackLeonardo Bras
Add flags to io_writev and introduce io_flush as optional callback to QIOChannelClass, allowing the implementation of zero copy writes by subclasses. How to use them: - Write data using qio_channel_writev*(...,QIO_CHANNEL_WRITE_FLAG_ZERO_COPY), - Wait write completion with qio_channel_flush(). Notes: As some zero copy write implementations work asynchronously, it's recommended to keep the write buffer untouched until the return of qio_channel_flush(), to avoid the risk of sending an updated buffer instead of the buffer state during write. As io_flush callback is optional, if a subclass does not implement it, then: - io_flush will return 0 without changing anything. Also, some functions like qio_channel_writev_full_all() were adapted to receive a flag parameter. That allows shared code between zero copy and non-zero copy writev, and also an easier implementation on new flags. Signed-off-by: Leonardo Bras <leobras@redhat.com> Reviewed-by: Daniel P.

Previously we would silently suppress VHOST_USER_PROTOCOL_F_CONFIG during the protocol negotiation if the QEMU stub hadn't implemented the vhost_dev_config_notifier. However this isn't the only way we can handle config messages, the existing vdc->get/set_config can do this as well. Lightly re-factor the code to check for both potential methods and instead of silently squashing the feature error out. It is unlikely that a vhost-user backend expecting to handle CONFIG messages will behave correctly if they never get sent.
