STATUS_ACPI_RS_ACCESS

STATUS_ACPI_RS_ACCESS reports failure during an access through ACPI region space. In the ACPI model, AML fields can map onto system memory, I/O, PCI configuration, embedded-controller, GPIO, serial bus and other operation-region spaces, each mediated by the appropriate access semantics or handler.

This is a runtime access result, not a declaration-only error. It differs from STATUS_ACPI_INVALID_REGION, where the region itself is invalid, and from STATUS_ACPI_REG_HANDLER_FAILED, where registration of an event handler failed. Here an already selected region-space access did not complete successfully.

An access through an ACPI region-space handler failed

  • Record the region name, space identifier, field, read or write direction, offset, width and access attributes.
  • Correlate the failure with the device or controller that implements that region space, including sleep or runtime-power state.
  • Determine whether the same access succeeds from other AML methods; that helps separate a general handler issue from bad field data.
