As your said, it is easy to add a new setup type. case IPMI_MEM_ADDR_SPACE: info->io_setup = mem_setup; info->io.addr_type = IPMI_MEM_ADDR_SPACE; break; case IPMI_IO_ADDR_SPACE: info->io_setup = port_setup; info->io.addr_type = IPMI_IO_ADDR_SPACE; break; case IPMI_VENDOR_ADDR_SPACE: info->io_setup = vendor_specific_setup; info->io.addr_type = IPMI_VENDOR_ADDR_SPACE; break; my question is: I want to submit this code to to kernel. Do you mind a vendor-specific function in the general ipmi driver ? Although I will use #ifdef for it . > > However, my big question is: How you are going to discover the > interface?

I can use DMI or DT. > > -corey > >> reguards. >> >> jung > > 2015-11-16 10:18 GMT+08:00, Corey Minyard <[email protected]>: > On 11/14/2015 09:59 PM, jung wrote: >> Hi,all >> In X86 platform, host communication with BMC controller through BT >> protocol, and the underlayer of BT is LPC (Low Pin Count), usually we >> use LPC in a tranparent mode, if we want to write an 0xa5 to LPC slave >> addr 0x2f8, just call outb(0xa5, 0x2f8).
