VMware Balloon driver

2010-04-24T18:31:26+00:00

This is a standalone version of VMware Balloon driver.  Ballooning is a
technique that allows hypervisor dynamically limit the amount of memory
available to the guest (with guest cooperation).  In the overcommit
scenario, when hypervisor set detects that it needs to shuffle some
memory, it instructs the driver to allocate certain number of pages, and
the underlying memory gets returned to the hypervisor.  Later hypervisor
may return memory to the guest by reattaching memory to the pageframes and
instructing the driver to "deflate" balloon.

We are submitting a standalone driver because KVM maintainer (Avi Kivity)
expressed opinion (rightly) that our transport does not fit well into
virtqueue paradigm and thus it does not make much sense to integrate with
virtio.

There were also some concerns whether current ballooning technique is the
right thing.  If there appears a better framework to achieve this we are
prepared to evaluate and switch to using it, but in the meantime we'd like
to get this driver upstream.

We want to get the driver accepted in distributions so that users do not
have to deal with an out-of-tree module and many distributions have
"upstream first" requirement.

The driver has been shipping for a number of years and users running on
VMware platform will have it installed as part of VMware Tools even if it
will not come from a distribution, thus there should not be additional
risk in pulling the driver into mainline.  The driver will only activate
if host is VMware so everyone else should not be affected at all.

MFGPT: move clocksource menu

2010-03-06T19:26:28+00:00

Move the CS5535 MFGPT hrtimer kconfig option to be with the other MFGPT
options.  This makes it easier to find and also removes it from the main
"Device Drivers" menu, where it should not have been.

cs5535: CS5535_MFGPT_DEFAULT_IRQ should depend on CS5535_MFGPT

2009-12-17T23:45:30+00:00

It doesn't make much sense to have CS5535_MFGPT_DEFAULT_IRQ show up in
configs that cannot have CS5535_MFGPT.

cs5535: drop the Geode-specific MFGPT/GPIO code

2009-12-15T16:53:28+00:00

With generic modular drivers handling all of this stuff, the
geode-specific code can go away.  The cs5535-gpio, cs5535-mfgpt, and
cs5535-clockevt drivers now handle this.

cs5535: add a generic MFGPT driver

2009-12-15T16:53:28+00:00

This is based on the old code on arch/x86/kernel/mfgpt_32.c, except it's
not x86 specific, it's modular, and it makes use of a PCI BAR rather than
a random MSR.  Currently module unloading is not supported; it's uncertain
whether or not it can be made work with the hardware.

ad525x_dpot: new driver for AD525x digital potentiometers

2009-12-15T16:53:25+00:00

This driver supports the non-volatile digital potentiometers via I2C:
AD5258, AD5259, AD5251, AD5252, AD5253, AD5254, and AD5255

It provides a sysfs interface to each device for reading/writing which
is documented in Documentation/misc-devices/ad525x_dpot.txt.

dell-laptop: remove duplicate Kconfig entry under drivers/misc

2009-12-10T05:03:18+00:00

This showed up as an unselectable option when using xconfig and
searching for "dell".  It must been overlooked when dell-laptop
was moved to drivers/platform/x86.
