NAME

ztop - show the Z3660's temperatures, voltages and CPU clock

SYNOPSIS

ztop [ -1 ] [ -i seconds ] [ -d device ]

DESCRIPTION

ztop reads the measurements the Z3660 accelerator's firmware makes — the values the AmigaOS ZTop shows — through the RTG driver, and shows them on the terminal, refreshed every two seconds: the FPGA, board and 68060 temperatures, the FPGA core and auxiliary voltages, the 3.3 V and 5 V rails, the supply of the LTC2990 monitor chip, and the CPU clock the preset sets. For each measurement it shows the latest value, a running average (each new value weighs one tenth, as in ZTop), and the lowest and highest seen. On a terminal the screen is redrawn; otherwise each refresh is printed as a block followed by an empty line.

It reads the information node /dev/zz9000i, which any user may open, and falls back to /dev/zz9000. It writes nothing to the board. A measurement the firmware does not offer is left out.

OPTIONS

-1

Print each measurement once, one line each, and exit. A line is a name, the value and its unit: fpga_temp, board_temp, cpu_temp in degrees Celsius, vcore, vaux, v3v3, v5, vcc in volts and cpu_mhz in MHz, for example

cpu_temp 45.6 C
v5 5.02 V

-i seconds

Refresh every seconds (1 to 60; the default is 2).

-d device

Read this device instead.

EXIT STATUS

0 when the values were shown; 1 when the device cannot be opened or its driver has no sensors call; 2 for a usage error; 3 when the board offers no sensors (a ZZ9000, or Z3660 firmware without them).

FILES

/dev/zz9000i

the RTG driver's information node (character 49, minor 128, mode 0444)

NOTES

The temperatures and voltages are the firmware's latest measurement; it takes a new set about once a second. The CPU clock is the value the preset asks for, not a measurement.
