nvdimm: Add realize, unrealize callbacks to NVDIMMDevice class

2022-02-18T07:34:13+00:00

A new subclass inheriting NVDIMMDevice is going to be introduced in subsequent patches. The new subclass uses the realize and unrealize callbacks. Add them on NVDIMMClass to appropriately call them as part of plug-unplug.

pc-dimm: remove unnecessary get_vmstate_memory_region() method

2021-05-14T14:26:18+00:00

The get_vmstate_memory_region() method from PCDIMMDeviceClass is only ever called from this class and is never overridden, so it can be converted into an ordinary function. This saves us from having to do an indirect call in order to reach it. Signed-off-by: Maciej S. Szmigiero Message-Id: Reviewed-by: Igor Mammedov Reviewed-by: Michael S.

memory: add a sparse memory device for fuzzing

2021-03-16T18:30:30+00:00

For testing, it can be useful to simulate an enormous amount of memory (e.g. 2^64 RAM). This adds an MMIO device that acts as sparse memory. When something writes a nonzero value to a sparse-mem address, we allocate a block of memory. For now, since the only user of this device is the fuzzer, we do not track and free zeroed blocks. The device has a very low priority (so it can be mapped beneath actual RAM, and virtual device MMIO regions). Signed-off-by: Alexander Bulekov Reviewed-by: Darren Kenny Signed-off-by: Paolo Bonzini

acpi: Permit OEM ID and OEM table ID fields to be changed

2021-02-05T13:52:59+00:00

Qemu's ACPI table generation sets the fields OEM ID and OEM table ID to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI table name. Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID and OEM table ID for the strings "BOCHS" and "BXPC" and if they are found, the game crashes(this may be an intentional detection mechanism to prevent playing the game in a virtualized environment). This patch allows you to override these default values. The feature can be used in this manner: qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN The oem-id string can be up to 6 bytes in size, and the oem-table-id string can be up to 8 bytes in size. If the string are smaller than their respective sizes they will be padded with space. If either of these parameters is not set, the current default values will be used for the one missing. Note that the the OEM Table ID field will not be extended with the name of the table, but will use either the default name or the user provided one. This does not affect the -acpitable option (for user-defined ACPI tables), which has precedence over -machine option.

memory-device: Add get_min_alignment() callback

2020-11-03T12:19:26+00:00

Add a callback that can be used to express additional alignment requirements (exceeding the ones from the memory region). Will be used by virtio-mem to express special alignment requirements due to manually configured, big block sizes (e.g., 1GB with an ordinary memory-backend-ram). This avoids failing later when realizing, because auto-detection wasn't able to assign a properly aligned address. Reviewed-by: Pankaj Gupta Cc: "Michael S.

qapi: Restrict device memory commands to machine code

2020-09-29T13:41:36+00:00

Only qemu-system-FOO and qemu-storage-daemon provide QMP monitors, therefore such declarations and definitions are irrelevant for user-mode emulation. Restricting the memory commands to machine.json pulls less QAPI-generated code into user-mode.

One of the goals of having less boilerplate on QOM declarations is to avoid human error. Requiring an extra argument that is never used is an opportunity for mistakes.
