From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thierry Reding Subject: [PATCH v2] arm64: tegra: Add CPU and cache topology for Tegra194 Date: Fri, 20 Sep 2019 16:56:21 +0200 Message-ID: <20190920145621.12527-1-thierry.reding@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Thierry Reding Cc: linux-tegra@vger.kernel.org, Joseph Lo , linux-arm-kernel@lists.infradead.org, Jon Hunter List-Id: linux-tegra@vger.kernel.org From: Thierry Reding Tegra194 has four CPU clusters, each with their own cache hierarchy. This patch creates the CPU map for these clusters and adds the second- and third-level caches and associates them with the CPUs.
