Subject: [edk2-devel] [PATCH v7 5/5] OvmfPkg/RiscVVirt: Override for RV CPU Features
Date: Sun, 29 Oct 2023 20:16:13 +0530 [thread overview]
Message-ID: <20231029144613.150580-6-dhaval@rivosinc.com> (raw)
In-Reply-To: <20231029144613.150580-1-dhaval@rivosinc.com>
This PCD provides a way for platform to override any
HW features that are default enabled by previous stages
of FW (like OpenSBI). For the case where previous/prev
stage has disabled the feature, this override is not
useful and its usage should be avoided.
