[Xen-devel] [PATCH 0/3] xen/x86: support setting dom0_mem depending on host size

[Juergen Gross <jgross@xxxxxxxx>]

Setting the memory size of dom0 on a server for the non autoballooning
case requires always specification of a boot parameter today. The value
to set will depend mostly on the host memory size.

In order to support that scenario add the possibility to set dom0_mem
depending on the amount of physical memory by allowing to specify a
percentage of host memory (e.g. 10%) with an offset (like 1G+10%).

To make it easy for a distributor to use such a setting as the default
make the standard setting for dom0_mem configurable via Kconfig.

Juergen Gross (3):
  xen/x86: delay parsing of dom0_mem parameter until needed
  xen/x86: add dom0 memory sizing variants
  xen/x86: add CONFIG item for default dom0 memory size
