Subject: [PATCH v4 26/26] docs: move numa=fake description to kernel-parameters.txt
Date: Wed, 7 Aug 2024 09:41:10 +0300 [thread overview]
Message-ID: <20240807064110.1003856-27-rppt@kernel.org> (raw)
In-Reply-To: <20240807064110.1003856-1-rppt@kernel.org>
From: "Mike Rapoport (Microsoft)" <rppt@kernel•org>
NUMA emulation can be now enabled on arm64 and riscv in addition to x86.
Move description of numa=fake parameters from x86 documentation of
admin-guide/kernel-parameters.txt
Suggested-by: Zi Yan <ziy@nvidia•com>
