Some question about dbus-sensors repo

[Deng Tyler]

Hi all:
    I am investigating dbus-sensors recently and I have lot of
questions(Sorry I am not familiar with it :(

In dbus-sesnsor,
struct peci_rd_pkg_cfg_msg msg;
msg.addr = config.addr;
msg.index = PECI_MBX_INDEX_DDR_DIMM_TEMP; <==== why use dimm temp to get
cpu temp?
msg.param = rank;
msg.rx_len = 4;
if (!ioctl(file, PECI_IOC_RD_PKG_CFG, &msg))
{

Could someone give me a hint? thanks.
Tyler
