Fix sensor missing issue. There is issue for "BMC randomly unable to get sensor readings". When invoking "ipmitool sdr" from Linux OS (host), it only returns three sensors like following partial records: [root@localhost ~]# ipmitool sdr CPU Power | 0 Watts | ok Memory Power | 0 Watts | ok Total Power | 0 Watts | ok [root@localhost ~]# There 2 caches sensorTree and sensorDataRecords. When sensorDataRecords cache and sensorTree cache is not sync, which causes this issue, like sensorTree cache has 10 sensors but there are just 5 sensors in sensorDataRecords cache. Most important sensorDataRecords cache is not necessary, ipmiStorageGetSDR could get data from dbus directly and no any performance impact. Using sensorMapUpdatePeriod(10s) but not sensorMapSdrUpdatePeriod(60s), 60 seconds are too long to answer user with some SDR content at the first time of BMC bootup. Tested: All sensors could be listed even at booting phase. Could print correct sensor set along with the boot progress. root@intel-obmc:~# ipmitool sdr CPU Power | 202 Watts | ok Memory Power | 0 Watts | ok Total Power | 312 Watts | ok root@intel-obmc:~# ipmitool sdr System Airflow | 14 unspecified | ok PSU1 In Current | 1.18 Amps | ok PSU1 Out Current | 20.80 Amps | ok PSU2 In Current | 0 Amps | ok PSU2 Out Current | no reading | ns Pwm 1 | 29.79 unspecifi | ok Pwm 2 | 29.79 unspecifi | ok Pwm 3 | 29.79 unspecifi | ok Pwm 4 | 29.79 unspecifi | ok Pwm 5 | 29.79 unspecifi | ok Pwm 6 | 29.79 unspecifi | ok Pwm 13 | 29.79 unspecifi | ok Pwm 14 | 29.79 unspecifi | ok Pwm 15 | 29.79 unspecifi | ok Pwm 16 | 29.79 unspecifi | ok Pwm PSU1 Fan 1 | 39.98 unspecifi | ok Pwm PSU1 Fan 2 | 39.98 unspecifi | ok .............

This component is intended to provide Intel-specific IPMI[3] command handlers for OpenBMC. These handlers are intended to integrate BMC with servers based on Intel architecture.
intel-ipmi-oem serves as an extension[1] to OpenBMC IPMI daemon[2]. It is compiled as a shared library and intended to both:
Related features provided by the library are grouped in separate source files. Main extensions to vanilla OpenBMC IPMI stack are the following:
