Move the framework, and the qat driver, to use `klog`
for logging and debug.
This has a some noticeable effects:
1) Our default log output gains a bunch of annotation:
From:
QAT device plugin started in 'dpdk' mode
To:
I0312 11:51:02.057728 6053 qat_plugin.go:64] QAT device plugin started in 'dpdk' mode
(there is now a command line option to drop those annotations if
necessary).
2) We gain a bunch of command line parameters from klog for controlling log
levels and output. We go from 5 arguments to 17:
---
Usage of ./cmd/qat_plugin/qat_plugin:
-add_dir_header
If true, adds the file directory to the header
-alsologtostderr
log to standard error as well as files
-debug
enable debug output
-dpdk-driver string
DPDK Device driver for configuring the QAT device (default "vfio-pci")
-kernel-vf-drivers string
Comma separated VF Device Driver of the QuickAssist Devices in the system. Devices supported: DH895xCC,C62x,C3xxx and D15xx (default "dh895xccvf,c6xxvf,c3xxxvf,d15xxvf")
-log_backtrace_at value
when logging hits line file:N, emit a stack trace
-log_dir string
If non-empty, write log files in this directory
-log_file string
If non-empty, use this log file
-log_file_max_size uint
Defines the maximum size a log file can grow to. Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
-logtostderr
log to standard error instead of files (default true)
-max-num-devices int
maximum number of QAT devices to be provided to the QuickAssist device plugin (default 32)
-mode string
plugin mode which can be either dpdk (default) or kernel (default "dpdk")
-skip_headers
If true, avoid header prefixes in the log messages
-skip_log_headers
If true, avoid headers when opening log files
-stderrthreshold value
logs at or above this threshold go to stderr (default 2)
-v value
number for the log level verbosity
-vmodule value
comma-separated list of pattern=N settings for file-filtered logging
---
3) Our `-debug` flag is now replaced by the `klog` `-v n` flag.
*NOTE:* This is potentially a minor breaking change. Applying
this debug overlay to any previous (pre-klog edit) images will
cause the container to fail to launch, as it will not recognise
the new `-v` arguments.
We also update the kustomize deployment to move from using
DEBUG env vars to adding a VERBOSITY var that controls both
the log verbosity and now the debug mode enabling.
