Method and apparatus for provision, access and control of an event log for a plurality of internal modules of a chipset

A method comprising:

• receiving a SMB buffer read command including a buffer address from an external micro-controller;
• requesting internal bus access from a bus arbiter;
• if bus access is granted, sending the SMB buffer read command to a module identified by the buffer address, wherein the module is at least one of a plurality of modules having an associated data buffer that logs data related to the operation of the module;
• receiving contents of the data buffer associated with the module identified by the buffer address;
• and
• forwarding the received contents of the data buffer to the external micro-controller.

A system comprising:

• a external communications bus;
• an external micro-controller coupled to the external communications bus;
• a system management bus controller coupled to the external communications bus and an internal communications bus;
• a plurality of modules coupled to the internal bus, each module having an associated memory, wherein the external micro-controller to issue a read command to the system management bus controller via the external communications bus, the system management bus controller to receive the read command and to forward the read command to at least one module of the plurality of modules via the internal bus and wherein responsive to the SMB buffer read command, the at least one module to forward contents of the memory to the system management bus controller via the internal bus.
