ATCA-8310 Installation and Use (6806800M72E) 166
v_dmc_is_golden Set to 1 if the FPGA bitstream image of DSP block (0..2) is corrupt
and the failsafe image has been loaded.
v_dmc_serial The serial number of DMC module 1 and 2 (n = 1 or 2 respectively)
v_dmc_ea MAC addresses of DSP modules (0..9) on DSP block (0..2).
v_shelf_name
v_shelf_prid
v_shelf_serial The product name, product ID and serial number stored in the IPMI
shelf FRU information (FRU ID 254 of shelf manager), product section
v_sserial_ch
v_sserial_brd
v_sserial_pr The serial numbers from the shelf FRU information (FRU ID 254 of
shelf manager), read from the chassis, board and product section
respectively.
v_ipmc_version The firmware version of the IPMC.
v_boottime The time (UNIX time) when the blade has started. If this variable is set
to "-1" then the RTC was not running at startup.
v_reset_cause Reflects the contents of the reset cause register in the glue logic
before clearing them. The value of the variable is a comma separated
list of reset indicators set at boot time:
"por" - indicates power-on reset
"pb_front" - face-plate pushbutton
"wdog" - FPGA Watchdog expired
"pb_rtm" - RTM pushbutton
"hrst" - SPP HRESET request
"ipmi" - IPMI reset (includes IPMI watchdog)
"soft" - If no reset cause was latched in the FPGA. Indicates soft reset.
mem The amount of physical memory in kilobytes. The encoded value is
decimal with "k" prefix. This takes the setting of the "pram" variable
into account.
v_bootm_size The amount of physical memory ib bytes. This takes the setting of the
"pmem" variable into account.
v_rtm_fpga_version The version of the FPGA on the RTM baseboard
v_rtm_tsi_version The version of the TSI FPGA on the RTM mezzaine module.
v_rtm_ext_version The version of the extender FPGA on the RTM mezzanine module.
v_dfl_dtb The address of the compiled-in device tree binary image.
v_physical_slot The physical slot number where the blade is mounted in.
