Hi Girish,
Thank you for this patch and for the effort for bringing forward dynamic
SMBIOS generation.
Please find my feedback inline marked [SAMI].

[SAMI] Do you have any thoughts on how the MemoryArrayHandle can be setup?
The same applies for the following MemoryErrorInformationHandle field.
I think we need some sort of a HandleManager in DynamicTablesFramework
that can keep track of the mappings between SMBIOS Objects and Table
Handles.
e.g. Smbios - HandleManager
+-------------------------------+-------------------------------+
| Object Token | Table Handle |
+-------------------------------+-------------------------------+
| Type16Obj_token | Type 16 Table handle |
+-------------------------------+-------------------------------+
...
- The Type17Object i.e. CM_ARM_MEMORY_DEVICE_INFO can then hold a token
for the Type16Object.
- If Type 17 table is to be installed, DynamicTablemanager shall
search the SMBIOS table list to see if a Type16 table is requested to be
installed.
- If a Type16 table is present in the list of SMBIOS table to install,
the Type16 table shall be installed first and an entry is made in the
Smbios HandleManager to create a mapping of Type16Obj_token <==> Type16
Table Handle.
- The Type17 table can now be built and if a the Type16Object token is
provided in CM_ARM_MEMORY_DEVICE_INFO, the Smbios HandleManager shall be
searched (using Type16Obj_token) to retrieve the Type16 Table handle and
populate the Type 17 Physical Memory Array Handle field.
I think we may have to experiment a bit before we arrive at the correct
design. However, please do let me know your thoughts on the above.
[SAMI]
+ 0, // MemoryErrorInformationHandle
+ 0xFFFF, // TotalWidth
+ 0xFFFF, // DataWIdth
[SAMI] I need to find out how these fields should be populated, but the
Annex A, SMBIOS specification version 3.6.0 says the following:
4.8.4 Total Width is not 0FFFFh (Unknown) if the memory device is
installed. (Size is not 0.)
4.8.5 Data Width is not 0FFFFh (Unknown).
Can you explain how this field is used, please?
[/SAMI]
+ 0x7FFF, // Size (always use Extended Size)
[SAMI] I think this field should be set based on the Size.
The spec says "If the size is 32 GB-1 MB or greater, the field value is
7FFFh and the actual size is stored in the Extended Size field."
I think it would be good to have a static function that encodes the
size in wither the Size field or the Extended Size field.
e.g. UpdateSmbiosTable17Size (SMBIOS_TABLE_TYPE17 *SmbiosRecord, UINTN
Size) {
if (Size > 32GB-1MB) {
SmbiosRecord->Size = EncodeSize (xxx);
} else {
SmbiosRecord->ExtendedSize = EncodeExtendedSize (xxx);
}
}

+ 1, // Device Locator
+ 2, // Bank Locator
+ MemoryTypeSdram, // MemoryType

[SAMI] Maybe we need a helper function (similar to
UpdateSmbiosTable17Size()) for this field as well.

[SAMI] Should this be provided through CM_ARM_MEMORY_DEVICE_INFO?

[SAMI] Should this be provided through CM_ARM_MEMORY_DEVICE_INFO?

while looking at the SMBIOS specification, section 7.18.5 for the

I think it will be useful to create UpdateSmbiosTable17Size() which does
the appropriate encoding and updation of the SMBIOS table fieds.
