Subject: [PATCH 8/8] Add documentation for extra boot parameters
Date: Fri, 5 May 2006 18:37:27 +0100 (IST) [thread overview]
Message-ID: <20060505173727.9030.40142.sendpatchset@skynet> (raw)
In-Reply-To: <20060505173446.9030.42837.sendpatchset@skynet>
Once all patches are applied, two new command-line parameters exist -
kernelcore and noeasyrclm. This patch adds the necessary documentation.

+ kernelcore=nn[KMG] [KNL,IA-32,IA-64,PPC,X86-64] This parameter
+ specifies the amount of memory usable by the kernel.
+ The requested amount is spread evenly throughout
+ all nodes in the system. The remaining memory
+ in each node is used for EasyRclm pages. In the
+ event, a node is too small to have both kernelcore
+ and EasyRclm pages, kernelcore pages will take
+ priority and other nodes will have a larger
+ number of kernelcore pages. The EasyRclm zone
+ is used for the allocation of pages on behalf
+ of a process and for HugeTLB pages. On ppc64,
+ it is likely that memory sections on this zone
+ can be offlined. Note that allocations like
+ PTEs-from-HighMem still use the HighMem zone if
+ it exists, and the Normal zone if it does not.
