2024-01-10docs/system/riscv: sifive_u: Update S-mode U-Boot image build instructionsBin Meng
Currently, the documentation outlines the process for building the S-mode U-Boot image using `make menuconfig` and manual actions within the menuconfig UI. However, this approach is fragile due to Kconfig options potentially changing across different releases. For example, CONFIG_OF_PRIOR_STAGE has been replaced by CONFIG_BOARD since v2022.01 release, and CONFIG_TEXT_BASE has been moved to the 'General setup' menu from the 'Boot options' menu in v2024.01 release. This update aims to make the S-mode U-Boot image build instructions future-proof. It leverages the 'config' script provided in the U-Boot source tree to edit the .config file, followed by a `make olddefconfig`. Validated with U-Boot v2024.01 release.

2023-12-20hw: Replace anti-social QOM type names (again)Markus Armbruster
QOM type names containing ',' result in awful UI. We got rid of them in v6.0.0 (commit e178113ff64 hw: Replace anti-social QOM type names). A few have crept back since: xlnx,cframe-reg xlnx,efuse xlnx,pmc-efuse-cache xlnx,versal-cfu-apb xlnx,versal-cfu-fdro xlnx,versal-cfu-sfr xlnx,versal-crl xlnx,versal-efuse xlnx,zynqmp-efuse These are all device types. They can't be plugged with -device / device_add, except for "xlnx,efuse" (I'm not sure that one is intentional). They *can* be used with -device / device_add to request help. Usability is poor, though: you have to double the comma, like this: $ qemu-system-aarch64 -device xlnx,,pmc-efuse-cache,help They can also be used with -global, where you must *not* double the comma: $ qemu-system-aarch64 -global xlnx,efuse.drive-index=2 Trap for the unwary. "xlnx,efuse", "xlnx,versal-efuse", "xlnx,pmc-efuse-cache", "xlnx-zynqmp-efuse" are from v6.2.0, "xlnx,versal-crl" is from v7.1.0, and the remainder are new.

It doesn't make sense to have two classes of flaky tests. While it may take the constrained environment of CI to trigger failures easily it doesn't mean they don't occasionally happen on developer machines. As CI is the gating factor to passing there is no point developers running the tests locally anyway unless they are trying to fix things.

2023-11-07vhost-user.rst: Migrating back-end-internal stateHanna Czenczek
For vhost-user devices, qemu can migrate the virtio state, but not the back-end's internal state. To do so, we need to be able to transfer this internal state between front-end (qemu) and back-end. At this point, this new feature is added for the purpose of virtio-fs migration. Because virtiofsd's internal state will not be too large, we believe it is best to transfer it as a single binary blob after the streaming phase. These are the additions to the protocol: - New vhost-user protocol feature VHOST_USER_PROTOCOL_F_DEVICE_STATE - SET_DEVICE_STATE_FD function: Front-end and back-end negotiate a file descriptor over which to transfer the state. - CHECK_DEVICE_STATE: After the state has been transferred through the file descriptor, the front-end invokes this function to verify success. There is no in-band way (through the file descriptor) to indicate failure, so we need to check explicitly. Once the transfer FD has been established via SET_DEVICE_STATE_FD (which includes establishing the direction of transfer and migration phase), the sending side writes its data into it, and the reading side reads it until it sees an EOF. Then, the front-end will check for success via CHECK_DEVICE_STATE, which on the destination side includes checking for integrity (i.e. errors during deserialization).

2023-11-07vhost-user.rst: Introduce suspended stateHanna Czenczek
In vDPA, GET_VRING_BASE does not stop the queried vring, which is why SUSPEND was introduced so that the returned index would be stable. In vhost-user, it does stop the vring, so under the same reasoning, it can get away without SUSPEND. Still, we do want to clarify that if the device is completely stopped, i.e. all vrings are stopped, the back-end should cease to modify any state relating to the guest. Do this by calling it "suspended".

2023-11-07vhost-user.rst: Clarify enabling/disabling vringsHanna Czenczek
Currently, the vhost-user documentation says that rings are to be initialized in a disabled state when VHOST_USER_F_PROTOCOL_FEATURES is negotiated. However, by the time of feature negotiation, all rings have already been initialized, so it is not entirely clear what this means. At least the vhost-user-backend Rust crate's implementation interpreted it to mean that whenever this feature is negotiated, all rings are to put into a disabled state, which means that every SET_FEATURES call would disable all rings, effectively halting the device. This is problematic because the VHOST_F_LOG_ALL feature is also set or cleared this way, which happens during migration. Doing so should not halt the device. Other implementations have interpreted this to mean that the device is to be initialized with all rings disabled, and a subsequent SET_FEATURES call that does not set VHOST_USER_F_PROTOCOL_FEATURES will enable all of them. Here, SET_FEATURES will never disable any ring. This interpretation does not suffer the problem of unintentionally halting the device whenever features are set or cleared, so it seems better and more reasonable. We can clarify this in the documentation by making it explicit that the enabled/disabled state is tracked even while the vring is stopped. Every vring is initialized in a disabled state, and SET_FEATURES without VHOST_USER_F_PROTOCOL_FEATURES simply becomes one way to enable all vrings.

Furthermore, it is not fully clear what the "base offset" these commands' documentation refers to is; an offset could be many things. Be more precise and verbose about it, especially given that these commands use different payload structures depending on whether the vring is split or packed.
