sysinfo: add sysinfo_get_and_detect() helper

2026-06-05T15:56:32Z

sysinfo_detect() is commonly called after sysinfo_get(). Make the API a bit more convenient to use by introducing a helper. Signed-off-by: Nora Schiffer Signed-off-by: Alexander Feilke Reviewed-by: Simon Glass

smbios: add support for dynamic generation of Type 16 table

2026-02-18T14:27:51Z

This commit implements SMBIOS Type 16 (Physical Memory Array) generation with a hybrid approach supporting both: 1. Explicit definition via Device Tree 'smbios' node: Child node under '/smbios/smbios/memory-array' will be used to populate as individual Type 16 structure directly. - Properties follow SMBIOS field names with lowercase letters and hyphen-separated words (e.g., 'memory-error-correction', 'maximum-capacity', 'extended-maximum-capacity', etc.). - This method supports precise platform-defined overrides and system descriptions. 2. Fallback to automatic DT-based discovery: If child node under '/smbios/smbios/memory-array' does not exist, the implementation will: - Scan all top-level 'memory@' nodes to populate Type 16 structure with inferred size and location data. - Scan nodes named or marked as 'memory-controller' and parse associated 'dimm@' subnodes (if present) to extract DIMM sizes and map them accordingly. This dual-mode support enables flexible firmware SMBIOS reporting while aligning with spec-compliant naming and runtime-detected memory topology. Type 16 support is under GENERATE_SMBIOS_TABLE_VERBOSE to avoid increasing rom size for those platforms which only require basic SMBIOS support.

sysinfo: Add SYSID_BOARD_RAM_SIZE_MB

2025-02-28T14:41:54Z

Add a new field SYSID_BOARD_RAM_SIZE_MB to sysinfo structure to store the size of RAM in MB. dram_init can use this field to get the RAM size via sysinfo driver. Signed-off-by: Baocheng Su

sysinfo: Add API for accessing data elements

2025-02-28T14:41:54Z

This commit introduces a new API to the sysinfo module, allowing access to data elements. This is particularly useful for handling data with multiple instances, such as MAC addresses. Signed-off-by: Baocheng Su

smbios: Fill UUID from sysinfo when available

2025-02-28T14:41:54Z

Allow for the sysinfo drivers to provide a system UUID to SMBIOS. Will be first used by the IOT2050 boards. Signed-off-by: Li Hua Qian Signed-off-by: Jan Kiszka Signed-off-by: Baocheng Su

sysinfo: Add sysinfo driver and data structure for smbios

2025-01-14T20:29:29Z

Add sysinfo driver to retrieve smbios information (Type 4 and 7). So that the smbios library can use it for getting values from the hardware platform instead of device tree. Signed-off-by: Raymond Mao

sysinfo: Add sysinfo API for accessing data area

2025-01-14T20:29:29Z

Add interface for sysinfo to access a data area from the platform. This is useful to save/read a memory region of platform-specific data. Signed-off-by: Raymond Mao

dm: sysinfo: Shorten the SYSINFO_ID prefix

2024-11-17T19:12:54Z

We are about to add a large number of new entries. Update the prefix to be a little shorter. For SMBIOS items, use SYSID_SM_ (for System Management) which is enough to distinguish it. For now at least, it seems that most items will be for SMBIOS. Signed-off-by: Simon Glass Acked-by: Raymond Mao

lib: smbios: Detect system properties via SYSINFO IDs

2024-06-20T17:41:43Z

Code is pretty much supports only DT properties and completely ignore information coming from sysinfo driver. Code is calling smbios_add_prop() which calls with smbios_add_prop_si(SYSINFO_ID_NONE). But SYSINFO_ID_NONE can't differentiate different entries from sysinfo driver. That's why introduce separate SYSINFO macros which can be used in sysinfo driver and passed to smbios structure.

headers: don't depend on errno.h being available

2024-01-24T16:12:11Z

These headers follow the pattern: | #if CONFIG_IS_ENABLED(FANCY_FEATURE) | void foo(void); | #else | static inline void foo(void) { return -ENOSYS; } | #endif In the #else path ENOSYS is used, however linux/errno.h is not included. If errno.h has not been included already the compiler errors out even if the inline function is not referenced. Make those headers self contained.
