<p class="MsoNormal"><span lang="EN-US">Hi Patrick,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">In previous projects, e.g., YV35, BICs bridge the IPMI command of Set/Get Boot Order sent from BIOS directly to the BMC, but in YV4, IPMI command is replaced by PLDM.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">As a result, we plan to translate the OEM IPMI command: Set (NetFn=0x30, Cmd=0x52) and Get (NetFn=0x30, Cmd=0x53) Boot Order sent from BIOS into standard command “SetBIOSAttributeCurrentValue” and “GetBIOSAttributeCurrentValueByHandle”
in PLDM for BIOS Control and Configuration (DSP0247). <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:12.0pt;text-indent:-12.0pt"><span lang="EN-US">Currently, the handlers for the 2 commands above have been implemented in pldmd to set/get the current value of a BIOSAttribute. (<a href="https://github.com/openbmc/pldm/blob/9e6631e201cf71895491987d93e8a343e05783b5/libpldmresponder/bios.cpp#L104">libpldmresponder/bios.cpp</a>)<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:12.0pt;text-indent:-12.0pt"><span lang="EN-US">Each BIOSAttribute can be different AttributeTypes, BIOSEnumeration, BIOSString, and BIOSInteger have been implemented. We want to add a new type “BIOSBootConfigSetting”.
(Can refer to Table 14: PLDM Representation of BIOSAttributeValueTableData in <a href="https://www.dmtf.org/sites/default/files/standards/documents/DSP0247_1.0.0.pdf">
DSP0247</a>)<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:12.0pt;text-indent:-12.0pt"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When Set/Get command comes in, it will find specific BIOSAttribute by searching the BIOSTable (i.e., BIOSTableObj at<a href="https://github.com/openbmc/pldm/blob/9e6631e201cf71895491987d93e8a343e05783b5/libpldmresponder/bios_config.hpp#L53">
libpldmresponder/bios_config.hpp</a>), there are CurrentValue and DefaultValue and OptionValue to represent the attribute’s value (a few lines above to BIOSTableObj), but the type is restricted to int64_t and string, which has only 1 element.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">BootConfigSetting is a series of BootSources, which should be a string array. We want to add string array to let BootConfigSetting can store multiple elements and add into BIOSTableObj. Since change the type of data type
might need a good amount of work, we wonder know if there is any concern to do it?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
