[edk2-devel] [PATCH v2 03/11] DynamicTablesPkg: Add TRBE interrupt to GICC object
Posted by Sami Mujawar 5 months, 2 weeks ago
ACPI 6.5 introduces a new filed to the MADT GICC structure
to specify the Trace Buffer Extension (TRBE) interrupt. The
TRBE interrupt is a Processor Private interrupt (PPI) and is
used to specify a platform-specific interrupt to signal TRBE
events.

Therefore, update the CM_ARM_GICC_INFO to reflect the addition
of the TRBE interrupt field.
