HV:Acrn-hypvervisor Root Directory Clean-up and create misc/ folder for Acrn daemons, services and tools.
This patch is to clean-up acrn-hypervisor root directory, targt only 5 folders under acrn-hypervisor:1.hypervisor,2.devicemodel,3.misc,4.doc,5.build Tracked-On: #3482 Signed-off-by: Terry Zou <terry.zou@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>

Usage:

[options]

-h: print this message
|

|
||||
Parses trace_data in binary format generated by acrntrace and
|
||||
reformats it according to the rules in the [formats] file.
|
||||
The rules in formats should have the format ({ and } show grouping
|
||||
and are not part of the syntax):
|
||||
|
||||
{event_id}{whitespace}{text format string}
|
||||
|
||||
The textual format string may include format specifiers, such as
|
||||
%(cpu)d, %(tsc)d, %(event)d, %(1)d, %(2)d, ....
|
||||
The 'd' format specifier outputs in decimal, alternatively 'x' will
|
||||
output in hexadecimal and 'o' will output in octal.
|
||||
|
||||
These respectively correspond to the CPU number (cpu), timestamp
|
||||
counter (tsc), event ID (event) and the data logged in the trace file.
|
||||
There can be only one such rule for each type of event.
