aspeed: Introduce a 'boot-emmc' machine option

2024-07-21T05:46:38Z

The default behavior of some Aspeed machines is to boot from the eMMC device, like the rainier-bmc. Others like ast2600-evb could also boot from eMMC if the HW strapping boot-from-eMMC bit was set. Add a property to set or unset this bit. This is useful to test boot images. For now, only activate this property on the ast2600-evb and rainier-bmc machines for which eMMC images are available or can be built.

hostmem: add a new memory backend based on POSIX shm_open()

2024-07-03T22:14:06Z

shm_open() creates and opens a new POSIX shared memory object. A POSIX shared memory object allows creating memory backend with an associated file descriptor that can be shared with external processes (e.g. vhost-user). The new `memory-backend-shm` can be used as an alternative when `memory-backend-memfd` is not available (Linux only), since shm_open() should be provided by any POSIX-compliant operating system. This backend mimics memfd, allocating memory that is practically anonymous. In theory shm_open() requires a name, but this is allocated for a short time interval and shm_unlink() is called right after shm_open(). After that, only fd is shared with external processes (e.g., vhost-user) as if it were associated with anonymous memory. In the future we may also allow the user to specify the name to be passed to shm_open(), but for now we keep the backend simple, mimicking anonymous memory such as memfd.
