commit 0f592e33934bf6108e33e34f00b425f98ee833ef
Author: Matthew Garrett <mjg@redhat.com>
Date: Wed Jul 8 19:04:23 2009 +0100
usb: Allow drivers to enable USB autosuspend on a per-device basis
USB autosuspend is currently only enabled by default for hubs. On other
hardware the decision is made by userspace. This is unnecessary in cases
where we know that the hardware supports autosuspend, so this patch adds
a function to allow drivers to enable it at probe time.

Subject: [PATCH] libata: Add ALPM power state accounting to the AHCI driver
PowerTOP wants to be able to show the user how effective the ALPM link
power management is for the user. ALPM is worth around 0.5W on a quiet
link; PowerTOP wants to be able to find cases where the "quiet link" isn't
actually quiet.
This patch adds state accounting functionality to the AHCI driver for
PowerTOP to use.
The parts of the patch are
1) the sysfs logic of exposing the stats for each state in sysfs
2) the basic accounting logic that gets update on link change interrupts
(or when the user accesses the info from sysfs)
3) a "accounting enable" flag; in order to get the accounting to work,
the driver needs to get phyrdy interrupts on link status changes.
Normally and currently this is disabled by the driver when ALPM is
on (to reduce overhead); when PowerTOP is running this will need
to be on to get usable statistics... hence the sysfs tunable.
The PowerTOP output currently looks like this:
Recent SATA AHCI link activity statistics
Active Partial Slumber Device name
0.5% 99.5% 0.0% host0
(work to resolve "host0" to a more human readable name is in progress)

Subject: drm/i915: enable memory self refresh on 9xx
Enabling memory self refresh (SR) on 9xx needs to set additional
register bits. On 945, we need bit 31 of FW_BLC_SELF to enable the
write to self refresh bit and bit 16 to enable the write of self
refresh watermark. On 915, bit 12 of INSTPM is used to enable SR.
SR will take effect when CPU enters C3+ state and its entry/exit
should be automatically controlled by H/W, driver only needs to set
SR enable bits in wm update. But this isn't safe in my test on 945
because GPU is hung. So this patch explicitly enables SR when GPU
is idle, and disables SR when it is busy. In my test on a netbook of
945GSE chipset, it saves about 0.8W idle power.

When no SSID is set, the reconnect decision should entirely be left to
userspace. The driver should not decide which AP to associate with based on
arbitrary policies.

From f56c995174cf42d84fdad06beebacd56e700b05d Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Sun, 25 Oct 2009 15:37:04 -0700
Subject: [PATCH] vfs: Add a trace point in the mark_inode_dirty function
PowerTOP would like to be able to show who is keeping the disk
busy by dirtying data. The most logical spot for this is in the vfs
in the mark_inode_dirty() function, doing this on the block level
is not possible because by the time the IO hits the block layer the
guilty party can no longer be found ("kjournald" and "pdflush" are not
useful answers to "who caused this file to be dirty).
The trace point follows the same logic/style as the block_dump code
and pretty much dumps the same data, just not to dmesg (and thus to
/var/log/messages) but via the trace events streams.

Toggling the link carrier is a non sense and is the grossest locking I can
think of. Moreover, it's giving a completely inaccurate status to userspace
who could for example decide to turn the interface down on carrier off
detection.

If we're not associated, we should not send wireless events to let userspace
know that we just left an ESSID, simply because we havent yet joined it.
If we keep on doing that, wpa_supplicant could receive such events while
actually trying to join an ESSID, and thus decide to stop trying. This leads
to a lot of connection failures as this driver seems to be sending GIWAP
events quite a lot.

Getting a probe response after sending a probe request to a specific SSID
doesnt mean we're trying to associate with this SSID.
wpa_supplicant should be the only one deciding when to join an SSID, not the
kernel.
