Subject: [RFC PATCH 04/10] OvmfPkg/RiscVVirt: Remove unimplemented NxForStack configuration
Date: Thu, 25 May 2023 16:30:35 +0200 [thread overview]
Message-ID: <20230525143041.1172989-5-ardb@kernel.org> (raw)
In-Reply-To: <20230525143041.1172989-1-ardb@kernel.org>
The RISC-V version of the DXE IPL does not implement setting the stack
NX, so before switching to an implementation that will ASSERT() on the
missing support, drop the PCD setting that enables it.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
