[Qemu-devel] [PATCH 0/4] make SMBUS/SATA/PIT configurable and introduce

[Chao Peng]

This patchset makes SMBUS/SATA/PIT configurable and introduces a new
machine type q35-lite with these features disabled by default. This is
useful for creating light weight virtual machine without boot time
penalty when these devices are unused. 

See https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg00422.html
for the background.

Chao Peng (4):
  pc: make smbus configurable
  pc: make sata configurable
  pc: make pit configurable
  q35: introduce q35-lite

[Qemu-devel] [PATCH 4/4] q35: introduce q35-lite

[Chao Peng]

This patch introduces a light weight machine type which shares the
same codebase with existing q35 machine type but with some features
disabled by default.
