suppress

Explicitly request the suppression or generation of the specified system information table type in the guest

Synopsis:

[system_table_type] suppress|generate

Description:

By default a QNX hypervisor always generates a Flattened Device Tree (FDT) when it runs on an ARM platform, and Advanced Configuration and Power Interface (ACPI) tables when it runs on an x86 platform. It doesn't currently support ACPI tables on ARM architectures or FDTs on x86 architectures, so the generate property is for future use only.

The system_table_type argument specifies the type of table to suppress or generate; this can be either fdt (ARM) or acpi (x86).

Examples:

The following suppresses the FDT system information table in an ARM guest:

fdt suppress

The following suppresses the ACPI system information table in an x86 guest:

acpi suppress
