SMBIOS Structure Types 0 through 127 (7Fh) are reserved
for and defined by the SMBIOS specification. Types 128
through 256 (80h to FFh) are available for system and
OEM-specific information.
Therefore, define a new type 'SMBIOS_TABLE_TYPE' that
represents a SMBIOS structure type and include it in
the definition of CM_STD_OBJ_SMBIOS_TABLE_INFO.

Some SMBIOS structure/table fields have dependency on other SMBIOS
structures/tables. These dependencies are established using handles
pointing to the dependent tables.
A SMBIOS table handle can be obtained by either installing a SMBIOS
table or by allocating a handle, which requires complex management
to avoid any clashes.
Obtaining a SMBIOS handle by installation requires that the dependent
table is installed before the parent SMBIOS table can be installed.
Therefore, introduce a SMBIOS table dispatcher that walks the SMBIOS
dependency list and schedules the dependent tables to be installed
before the parent table is installed.

Notes:
v2:
- Update dispatcher state machine to remove StUnknown. [SAMI]
- Move extern function to header file and move debug [ABNER]
code together.
- Updated code based on review feedback to move extern [SAMI]
function to header file and also moved the debug code
together.

Hi Sami
Thanks for v2, I will apply these to my tree and test it out.
One small comment before I review/test the patch train inline (prefixed

[GM]
This ASSERT will be hit even if we have multiple SMBIOS CM objects of
the same type which is legal (for e.g there are multiple tables for
type17/19 )
[SAMI] The understanding is that SmbiosTableInfo[] will only contain one entry for a given TableType as it is used to indicate which generators are to be instantiated.
Following is the sequence of operations:
- The dispatcher is initialised in InitSmbiosTableDispatcher(), which will set the mSmBiosDispatcher[<Table_Type>].State to StPresent if SmbiosTableInfo[] contains a table of Table_Type.
- SmbiosTableInfo[] will only contain one entry for each table type, e.g. even if there are multiple Type17/Type19 tables to be installed. This entry indicates that table(s) of Type17/Type19 is/are requested to be installed and that the corresponding generator must be instantiated.
- Once the SMBIOS table generator is instantiated, it will then request for the object(s) of the required type from the Configuration Manager that are required to construct the table.
- The generator can then decide if multiple SMBIOS tables are to be constructed based on the objects returned by the Configuration Manager. e.g. if multiple Cm_Type17_objects are returned then the corresponding number of Type17 tables will be built by the generator.
Therefore, I think we should not hit the above assert.
However, the code that may need to change/extend is the call to BuildAndInstallSmbiosTable(). I am not sure if we need to indicate that there could be multiple SMBIOS tables that may be installed. For now, BuildAndInstallSmbiosTable() implies that a generator of the specified type is to be instantiated for building the SMBIOS table of the specified type.
Hope this clarifies the scenario and please do let me know if I am missing something.
Also, I have only tested this patch with simulated data and there may be some issues that we may find when the full stack is integrated.
So, thank you for going through the patch in detail.

[GM]
That sounds right, I'd made a mistake when installing the CM objects.
I should be installing one of each SMBIOS table so that
GetEStdObjSmbiosTableList gets the list of the available tables and each
generator should install multiple tables of a given type based on the
number of CM objects available.
I did expand the existing SMBIOS factory code to install multiple tables.
Thanks for the clarification.
Best Regards
Girish
> However, the code that may need to change/extend is the call to BuildAndInstallSmbiosTable(). I am not sure if we need to indicate that there could be multiple SMBIOS tables that may be installed. For now, BuildAndInstallSmbiosTable() implies that a generator of the specified type is to be instantiated for building the SMBIOS table of the specified type.

[SAMI] No worries. Please let me know if you face any issues with the
dispatcher or if you identify any problem during integration.

Hi Sami
Your patches worked. There was just one thing I had to add to get
compile to work. (inline with [GM]), other than that I think you can get
this in.
We've implemented about 18 table generators. (Types 0, 1, 2, 3, 8, 9,
11, 13, 14, 16, 17, 19, 32, 38, 39, 41, 43, 45)
Two more are under way (Type 4.7).
I've setup a github repo here
https://github.com/tianocore/edk2/compare/master...gmahadevan:edk2-upstream:RFC/smbios-dyntables-v2?expand=1
I could send you one massive patch train (22 patches or so) or split it
up into smaller chunks perhaps just the table generation stuff first and
then each generator library.
Let me know.
Best Regards
Girish

Hi Girish,
Thank you for taking this effort forward

[SAMI] Thanks for testing these patches.

[SAMI] I would be keen to understand how the Type 4 and 7 generators
would work as I would prefer to avoid duplication of data.

[SAMI] Thanks for sharing the github branch. Please also share a github
branch when you send out your patches for review.

[SAMI] I think it may be good to split the patch series to include table
generation and then 1 or 2 generators to understand the code flow. The
remaining generators can follow later. I think Type 4 and 7 would be
really interesting, but you can send what you already have.

[SAMI] Yes, you are correct. I had tested my changes only using
simulation so may have removed the stub function when posting the patches.

As a first pass we're setting up the generators to just blindly use
SMBIOS specific CM objects to setup these tables.
Second pass could be to have the generators try to rely on ACPI objects
(PPTT) or fallback to Architecture specific libraries to figure out how
to populate these tables. Honestly we need to think about this a little
more, we'd love to swap notes.
(We are in the prelim stages of these so haven't gotten very far)

Will do.

ok, I will send out a patch train for the core generator code and 2 of
the Generators.

Update the SMBIOS table dispatcher dependency table to add the
table dependencies for SMBIOS table Type 19, Type 20, Type 27,
Type 35 and Type 37.
The SMBIOS table Type 35 can have dependency on 6 other SMBIOS
tables. Therefore, increase the MAX_SMBIOS_DEPENDENCY to 6, and
also update the SMBIOS table dispatcher table accordingly.

Some SMBIOS tables do not have a fixed dependency and can depend on any
other SMBIOS tables. Therefore, the SMBIOS dispatcher cannot define a
fixed sequence for dispatching these tables. A possible solution is to
defer the dispatch of such SMBIOS tables towards the end, assuming that
the dependent SMBIOS tables would have been dispatched by then.
Therefore, introduce a dispatch order attribute such that SMBIOS tables
that have a fixed dependency sequence are configured as Default Ordered,
and the SMBIOS tables that do not have a fixed dependency have an Order
attribute specifying an Order Level. An Order Level is used to sequence
the dispatch of Ordered SMBIOS tables.
The Default Ordered SMBIOS tables are dispatched first and a dependency
walk is performed to dispatch the dependent tables by iterating through
the SMBIOS_TABLE_DISPATCHER.Dependency[].
Once all Default ordered SMBIOS tables have been dispatched, the Ordered
SMBIOS tables would be scheduled for dispatch in increasing order as of
the Order Level, e.g. OrderL1, OrderL2, ...
Note: The dispatcher does not perform a dependency walk for the Ordered
SMBIOS tables as the expectation is that the dependent SMBIOS tables
would be already dispatched.
A top level dispatch function DispatchSmbiosTables() has been introduced
to schedule the dispatch of Default Ordered and Ordered SMBIOS tables.
