documentation: poky-ref-manual, mega-manual, Makefile - new variables
Added variable descriptions for BB_DISKMON_DIRS and BB_DISKMON_WARNINTERVAL. These went in the reference manual in the glossary section. First draft for both descriptions. Also, updated the Makefile to include two new figures used in the Build History section. The figures needed to be added to the TARFILE variable so that the .PNG files are included when publishing both the poky-ref-manual and the mega-manual. Added two figures to the figures directories of the poky-ref-manual and the mega-manual. These figures are part of the new Build History section. Anytime you add a figure to any manual you also have to store it in the figures directory of the mega-manual.

<para>
|

Monitors disk space and available inodes during the build
|

and allows you to control the build based on these
|
||||
parameters.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
Disk space monitoring is disabled by default.
|
||||
To enable monitoring, add the <filename>BB_DISKMON_DIRS</filename>
|
||||
variable to your <filename>conf/local.conf</filename> file found in the
|
||||
<ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink>.
|
||||
Use the following form:
|
||||
<literallayout class='monospaced'>
|
||||
BB_DISKMON_DIRS = "<action>,<dir>,<threshold> [...]"
|
||||
|
||||
where:
|
||||
|
||||
<action> is:
|
||||
ABORT: Immediately abort the build when
|
||||
a threshold is broken.
|
||||
STOPTASKS: Stop the build after the currently
|
||||
executing tasks have finished when
|
||||
a threshold is broken.
|
||||
WARN: Issue a warning but continue the
|
||||
build when a threshold is broken.
|
||||
Subsequent warnings are issued as
|
||||
defined by the
|
||||
<link linkend='var-BB_DISKMON_WARNINTERVAL'>BB_DISKMON_WARNINTERVAL</link> variable,
|
||||
which must be defined in the
|
||||
conf/local.conf file.
|
||||
|
||||
<dir> is:
|
||||
Any directory you choose. You can specify one or
|
||||
more directories to monitor by separating the
|
||||
groupings with a space. If two directories are
|
||||
on the same device, only the first directory
|
||||
is monitored.
|
||||
|
||||
<threshold> is:
|
||||
Either the minimum available disk space,
|
||||
the minimum number of free inodes, or
|
||||
both. You must specify at least one. To
|
||||
omit one or the other, simply omit the value.
|
||||
Specify the threshold using G, M, K for Gbytes,
|
||||
Mbytes, and Kbytes, respectively. If you do
|
||||
not specify G, M, or K, Kbytes is assumed by
|
||||
default. Do not use GB, MB, or KB.
|
||||
</literallayout>
|
||||
</para>
|
||||
|
||||
<para>
|
||||
Here are some examples:
|
||||
<literallayout class='monospaced'>
|
||||
BB_DISKMON_DIRS = "ABORT,${TMPDIR},1G,100K WARN,${SSTATE_DIR},1G,100K"
|
||||
BB_DISKMON_DIRS = "STOPTASKS,${TMPDIR},1G"
|
||||
BB_DISKMON_DIRS = "ABORT,${TMPDIR},,100K"
|
||||
</literallayout>
|
||||
The first example works only if you also provide
|
||||
the <link linkend='var-BB_DISKMON_WARNINTERVAL'><filename>BB_DISKMON_WARNINTERVAL</filename></link> variable
|
||||
in the <filename>conf/local.conf</filename>.
|
||||
This example causes the build system to immediately
|
||||
abort when either the disk space in <filename>${TMPDIR}</filename> drops
|
||||
below 1 Gbyte or the available free inodes drops below
|
||||
100 Kbytes.
|
||||
Because two directories are provided with the variable, the
|
||||
build system also issue a
|
||||
warning when the disk space in the
|
||||
<filename>${SSTATE_DIR}</filename> directory drops
|
||||
below 1 Gbyte or the number of free inodes drops
|
||||
below 100 Kbytes.
|
||||
Subsequent warnings are issued during intervals as
|
||||
defined by the <filename>BB_DISKMON_WARNINTERVAL</filename>
|
||||
variable.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The second example stops the build after all currently
|
||||
executing tasks complete when the minimum disk space
|
||||
in the <filename>${TMPDIR}</filename> directory drops
|
||||
below 1 Gbyte.
|
||||
No disk monitoring occurs for the free inodes in this case.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The final example immediately aborts the build when the
|
||||
number of free inodes in the <filename>${TMPDIR}</filename> directory
|
||||
drops below 100 Kbytes.
|
||||
No disk space monitoring for the directory itself occurs
|
||||
in this case.

<para>
|

Defines the disk space and free inode warning intervals.
|
||||
To set these intervals, define the variable in your
|

<filename>conf/local.conf</filename> file in the

<ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink>.
|

</para>

|

<para>
|

If you are going to use the
|
||||
<filename>BB_DISKMON_WARNINTERVAL</filename> variable, you must
|
||||
also use the
|
||||
<link linkend='var-BB_DISKMON_DIRS'><filename>BB_DISKMON_DIRS</filename></link> variable
|
||||
and define its action as "WARN".
|
||||
During the build, subsequent warnings are issued each time
|
||||
disk space or number of free inodes further reduces by
|
||||
the respective interval.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
Use the following form:
|
||||
<literallayout class='monospaced'>
|
||||
BB_DISKMON_WARNINTERVAL = "<disk_space_interval>,<disk_inode_interval>"
|
||||
|
||||
where:
|
||||
|
||||
<disk_space_interval> is:
|
||||
An interval of memory expressed in either
|
||||
G, M, or K for Gbytes, Mbytes, or Kbytes,
|
||||
respectively. You cannot use GB, MB, or KB.
|
||||
|
||||
<disk_inode_interval> is:
|
||||
An interval of free inodes expressed in either
|
||||
G, M, or K for Gbytes, Mbytes, or Kbytes,
|
||||
respectively. You cannot use GB, MB, or KB.
|
||||
</literallayout>
|

</para>
|

|

<para>
|
||||
Here is an example:
|
||||
<literallayout class='monospaced'>
|
||||
BB_DISKMON_DIRS = "WARN,${SSTATE_DIR},1G,100K"
|
||||
BB_DISKMON_WARNINTERVAL = "50M,5K"
|
||||
</literallayout>
|
||||
These variables cause the OpenEmbedded build system to
|
||||
issue subsequent warnings each time the available
|
||||
disk space further reduces by 50 Mbytes or the number
|
||||
of free inodes further reduces by 5 Kbytes in the
|
||||
<filename>${SSTATE_DIR}</filename> directory.
|
||||
Subsequent warnings based on the interval occur each time
|
||||
a respective interval is reached beyond the intial warning
|
||||
(i.e. 1 Gbytes and 100 Kbytes).
