Subject: [PATCH v4 10/13] x86/platform/uv: Update Node Present Counting
Date: Mon, 5 Oct 2020 15:39:26 -0500 [thread overview]
Message-ID: <20201005203929.148656-11-mike.travis@hpe.com> (raw)
In-Reply-To: <20201005203929.148656-1-mike.travis@hpe.com>
The changes in the UV5 arch shrunk the NODE PRESENT table to just 2x64
entries (128 total) so are in to 64 bit MMRs instead of a depth of 64
bits in an array. Adjust references when counting up the nodes present.
