emulation: Use bloblist to hold tables

2025-01-22T23:08:23Z

QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot copies out the SMBIOS tables but points directly to the ACPI ones. The ACPI tables are not aligned on a 4KB boundary, which means that UPL cannot use them directly, since it uses a reserved-memory node for the tables and that it assumed (by EDK2) to be 4KB-aligned. On x86, QEMU provides the tables in a mapped memory region and U-Boot makes use of these directly, thus making it difficult to use any common code. Adjust the logic to fit within the existing table-generation code. Use a bloblist always and ensure that the ACPI tables is placed in an aligned region. Set a size of 8K for QEMU. This does not actually put all the tables in one place, for QEMU, since it currently adds a pointer to the tables in QFW. On ARM, enable bloblist so that SMBIOS tables can be added to the bloblist.

smbios: correctly name Structure Table Maximum Size field

2024-02-02T18:57:45Z

In the SMBIOS 3 entry point the Structure Table Maximum Size field was incorrectly named max_struct_size. A Maximum Structure Size field only exists in the SMBIOS 2.1 entry point and has a different meaning. Call the Structure Table Length field table_maximum_size. Signed-off-by: Heinrich Schuchardt

smbios: use struct_table_length to get SMBIOS 2.1 total table length

2024-01-26T13:16:46Z

The current code convert the SMBIOS 2.1 entry point structure to SMBIOS 3.0 entry point structure. The max_struct_size member in SMBIOS 2.1 entry point structure indicates "Size of the largest SMBIOS structure, in bytes". We need to use struct_table_length instead.

smbios: copy QEMU tables

2024-01-16T22:05:29Z

QEMU provides SMBIOS tables with detailed information. We should not try to replicate them in U-Boot. If we want to inform about U-Boot, we can add a Firmware Inventory Information (type 45) table in future. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass
