fpgad¶
SYNOPSIS¶
fpgad --daemon [--directory=<dir>] [--logfile=<file>] [--pidfile=<file>] [--umask=<mode>] [--socket=<sock>] [--null-bitstream=<file>]
fpgad [--socket=<sock>] [--null-bitstream=<file>]
DESCRIPTION¶
fpgad
periodically monitors and reports the error status reflected
in the device driver’s error status sysfs files. fpgad
establishes
the channel to communicate events to the Open Programmable Accelerator
Engine (OPAE) application. fpgad
programs a NULL bitstream in
response to an AP6 (power) event. fpgad
is only available on the
Integrated FPGA Platform. You cannot run fpgad
on the Intel®
Progammable Accelerator Cards (PACs).
If your system does not support interrupts, you must run fpgad
before the API calls fpgaRegisterEvent
and fpgaUnregisterEvent
can succeed.
Use SIGINT to stop fpgad
.
-d, --daemon
When specified, fpgad executes as a system daemon process.
-D, --directory <dir>
When running in daemon mode, run from the specified directory.
If omitted when daemonizing, `fpgad` uses /tmp.
-l, --logfile <file>
When running in daemon mode, send output to file. When not in daemon mode, the output goes to stdout.
If omitted when daemonizaing, fpgad uses /tmp/fpgad.log.
-p, --pidfile <file>
When running in daemon mode, write the daemon's process id to a file.
If omitted when daemonizing, fpgad uses /tmp/fpgad.pid.
-m, --umask <mode>
When running in daemon mode, use the mode value as the file mode creation mask passed to umask.
If omitted when daemonizing, fpgad uses 0.
-s, --socket <sock>
Listen for event API registration requests on the UNIX domain socket on the specified path.
The default=/tmp/fpga_event_socket.
-n, --null-bitstream <file>
Specify the NULL bitstream to program when an AP6 event occurs. This option may be specified multiple
times. The AF, if any, that matches the FPGA's PR interface ID is programmed when an AP6
event occurs.
TROUBLESHOOTING¶
If you encounter any issues, you can get debug information in two ways:
- By examining the log file when in daemon mode.
- By running in non-daemon mode and viewing stdout.
EXAMPLES¶
fpgad --daemon --null-bitstream=my_null_bits.gbs
