NvSciIpc Configuration Data
NvSciIpc configuration data is used to define all the channels present for a given Guest VM. Currently these details are provided via the plain text configuration file, where each line contains details about a single NvSciIpc channel in the system.
Each channel entry is added to the plain text configuration file in string list form.
For INTER_THREAD and INTER_PROCESS backend, the format is :
<Backend-Name>, <Endpoint-Name>, <Endpoint-Name>, <Backend-Specific-Data>,
For INTER_VM and INTER_CHIP backend, the format is :
<Backend-Name>, <Endpoint-Name>, <Backend-Specific-Data>,
<Endpoint-Name>
is unique string that is used to tag/identify a single NvSciIpc endpoint in a system. Ideally it should describe the purpose for which the NvSciIpc endpoint is created.
For INTER_THREAD and INTER_PROCESS backends, two endpoint names must be defined.
<Backend-Name>
must be one of the following:
- INTER_THREAD
- INTER_PROCESS
- INTER_VM
- INTER_CHIP
<Backend-Specific-Data>
may span multiple fields.
The INTER_THREAD and INTER_PROCESS backend contains two (2) integer fields that describe <No-of-Frames Frame-Size>
tuple. <Frame-Size>
must be multiples of 64 bytes.
INTER_VM contains a single integer field that denotes the IVC queue ID.
INTER_CHIP contains a single integer field that denotes the inter-chip device number.
For Linux VMs, the configuration data above is passed as a plain text file in the root file system. It is located at: /etc/nvsciipc.cfg
