[RFC PATCH v4 07/20] RISC-V: Kconfig: Select deferred GSI probe for ACPI systems

From: Sunil V L
Date: Mon Apr 15 2024 - 13:03:55 EST


On RISC-V platforms, apart from root interrupt controllers (which
provide local interrupts and IPI), other interrupt controllers in the
hierarchy are probed late. Enable this CONFIG option for RISC-V ACPI
based platforms.
