Sant" MIME-Version: 1.0 To: linuxppc-dev@ozlabs.org Subject: [Patch 0/2] Kexec/Kdump support POWER6 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Cc: Milton Miller II , ellerman@au1.ibm.com Reply-To: sachinp@in.ibm.com List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Here are a set of patches which adds kdump support for Power6. The first patch reads VRMA page size from device tree. Second patch adds Kexec/Kdump support for Power6 processor. On Power machines supporting VRMA, Kexec/Kdump does not work. Hypervisor stores VRMA mapping used by the OS, in the hpte hash tables. This patch makes sure these hpte entries are left untouched. Comments are welcome.
