To configure your system image with support for file systems and related hardware through the Ews graphical user interface, follow this procedure:
Open your system image configuration in ews:
host% cd build_dir host% ews conf/ChorusOS.xml & |
Use the hints in the following tables to set features and tunables for the file system support needed.
The following table lists the feature and tunable settings required for your ChorusOS system to support the media on which you use file systems.
Table 4-2 Media Support
The following table summarizes the feature and tunable settings required for your ChorusOS system to support specific file systems.
Table 4-3 File System Support
The iom.nbuf
tunable sets the number of buffer
cache entries. These are the standard buffered entries used for input and
output. The larger the value, the larger the cache available. The iom.nbuf
tunable, and other tunables, influence the amount of RAM used by the system.
The iom.kmemsize
tunable sets the amount of
memory available to the microkernel through kmemalloc
.
The iom.clusterssize
and iom.nmbufs
set the number of clusters and mbufs used for networking. The
larger the value, the larger the number of network requests that can successfully
be satisfied.
Save your changes to the system image configuration.
Build the system image.
To configure your system image with support for file systems and related hardware through the configurator(1CC) command-line interface, follow this procedure:
Change to the directory where you build system images:
host% cd build_dir |
Use the hints in the tables provided (see Step 2) to set features and tunables for the file system support needed.
configurator(1CC) commands to set features and tunables take the form:
host% configurator -c conf/ChorusOS.xml -set feature | tunable=value |
Build the system image to include the modifications you have made:
host% make system_image_name |
