Subject: [PATCH v4 0/6] Add dmops to allow use of VGA with restricted QEMU
Date: Tue, 23 Jan 2018 15:22:40 +0000	[thread overview]
Message-ID: <20180123152246.22031-1-ross.lagerwall@citrix.com> (raw)

The recently added support for restricting QEMU prevents use of the VGA
console. This series addresses that by adding a couple of new dmops.
A corresponding patch for QEMU is needed to make use of the new dmops.

Changes in v4:
* Rename add_to_physmap -> relocate_memory.
* Use continutation instead of erroring in relocate_memory.
* Bump domctl interface version.

Changes in v3:
* Address Jan's comments - primarily adding a new patch to remove the
  existing pin_mem_cacheattr domctl.

Changes in v2:
* Address Paul's comments - mainly making add_to_physmap operate on a
  range.

Ross Lagerwall (6):
  xen/mm: Make xenmem_add_to_physmap global
  x86/hvm: Provide XEN_DMOP_relocate_memory
  x86/hvm: Provide XEN_DMOP_pin_memory_cacheattr
  tools: libxendevicemodel: Provide xendevicemodel_relocate_memory
  tools: libxendevicemodel: Provide xendevicemodel_pin_memory_cacheattr
  x86/domctl: Remove XEN_DOMCTL_pin_mem_cacheattr
