Subject: [RFC PATCH v2 03/21] ACPI: Kconfig: Introduce new option to support deferred GSI probe
Date: Thu, 26 Oct 2023 01:53:26 +0530	[thread overview]
Message-ID: <20231025202344.581132-4-sunilvl@ventanamicro.com> (raw)
In-Reply-To: <20231025202344.581132-1-sunilvl@ventanamicro.com>

On some architectures like RISC-V, the interrupt controllers for Global
System Interrupts (GSI) are not probed early during boot. So, the
device drivers which need to register their GSI, need to be deferred
until the actual interrupt controller driver is probed. To reduce the
impact of such change, add a new CONFIG option which can be set only by
the architecture which needs deferred GSI probing.
