[edk2-devel] 回复: [PATCH] MdePkg/Include: Add IPMI KCS definitions

Posted by gaoliming via groups.io 1 year, 1 month ago

Abner:
  This patch also adds one PCD PcdIpmiKcsBaseAddress. I see its default
value is 0xca2. Can you add comments for this default value?

Thanks

Re: [edk2-devel] 回复: [PATCH] MdePkg/Include: Add IPMI KCS definitions

Posted by Michael D Kinney 1 year, 1 month ago

Is that an I/O Port address or an MMIO address?  Can it be either?

If it must be I/O Port address, then the PCD name should convey that.

If it can be either, then need another PCD to specify the type so the
Code can do the access with the correct IoLib APIs.

Mike

In IPMI spec, KCS register base address is defined as I/O mapped 0xca2.
For MCTP over KCS, KCS register base address could be either I/O mapped or memory mapped.

Sounds good. I will update the PCD name.

We do have a PCD for KCS access type, but that was defined in the Manageability package and leverage by both IPMI driver, MCTP driver and KCS manageability transport library.

Hi Abner,

Any plan to support SMBUS system interface (ssif)?

Re: [edk2-devel] [PATCH] MdePkg/Include: Add IPMI KCS definitions

Posted by Chang, Abner via groups.io 1 year, 1 month ago

[AMD Official Use Only - General]

Hi Tinh,
That depends on if AMD platform enables SSIF as host-bmc transport interface, otherwise I may not work on that because I have no platform to test.
Thanks

Re: [edk2-devel] [PATCH] MdePkg/Include: Add IPMI KCS definitions

Posted by Chang, Abner via groups.io 1 year, 1 month ago

[AMD Official Use Only - General]

Ok, that would be the patch set for edk2-platform I am going to send later,  will update these two edk2 industry standard definition patches (KCS and MCTP) after edk2-platforms one.

Thanks
Abner

Posted by Michael D Kinney 1 year, 1 month ago
