PM: Split up sysdev_[suspend|resume] from device_power_[down|up]

2009-02-22T18:33:44+00:00

Move the sysdev_suspend/resume from the callee to the callers, with
no real change in semantics, so that we can rework the disabling of
interrupts during suspend/hibernation.

This is based on an earlier patch from Linus.

xen: make sysfs files behave as their names suggest

2009-01-29T12:20:36+00:00

1: make "target_kb" only accept and produce a memory size in kilobytes.
2: add a second "target" file which produces output in bytes, and will accept
   memparse input (scaled bytes)

This fixes the rather irritating problem that writing the same value
read back into target_kb would end up shrinking the domain by a factor
of 1024, with generally bad results.

xen: unitialised return value in xenbus_write_transaction

2009-01-26T13:29:26+00:00

The return value of xenbus_write_transaction can be uninitialised in
the success case leading to the userspace xenstore utilities failing.

xen: handle highmem pages correctly when shrinking a domain

2009-01-23T17:55:28+00:00

Commit 1058a75f07b9bb8323fb5197be5526220f8b75cf ("xen: actually release
memory when shrinking domain") causes a crash if the page being released
is a highmem page.

If a page is highmem then there is no need to unmap it.

xen: actually release memory when shrinking domain

2009-01-22T22:41:44+00:00

Fix this:

> It appears that in the upstream balloon driver,
> the call to HYPERVISOR_update_va_mapping is missing
> from decrease_reservation.  I think as a result,
> the balloon driver is eating memory but not
> releasing it to Xen, thus rendering the balloon
> driver essentially useless.  (Can be observed via xentop.)

xen: add xenfs to allow usermode <-> Xen interaction

2009-01-08T16:30:59+00:00

The xenfs filesystem exports various interfaces to usermode.  Initially
this exports a file to allow usermode to interact with xenbus/xenstore.

Traditionally this appeared in /proc/xen.  Rather than extending procfs,
this patch adds a backward-compat mountpoint on /proc/xen, and provides
a xenfs filesystem which can be mounted there.
