This driver is based of the TZCOM (planned to be deprecated soon).
It shares the same design as TZCOM with some re-organization and
new features added. QSEEcom (Qualcomm Secure Execution environment
Communicator) is named accordingly to be consistent with the
nomenclature used in the secure domain. The following additional
features (on top of current TZCOM) driver are implemented:
(1) Add support for multi-image loading.
The image that was loaded in TZCOM was hard-coded to "tzapps".
During a open() tzapps was loaded using pil driver call pil_get().
This severly limted the number of images that could be loaded to
one single application: named "tzapps". qseecom driver provides a
way to load any image on request. Client simply send the image
data in a specific format and this data is sent over to QSEE
(Qualcomm Secure Execution enviroment) to load accordingly.
(2) Add support for multi-client.
TZcom driver did not have provisions to support multiple clients
to interface with the single tzapp image loaded on the secure
domain. The changes added in qseecom driver allows for multiple
client to interface with a single image laoded and running in
secure domain.
(3) Add support for performance tweaking in QSEE
Added capability to send requests to QSEE to set specific clocks
for optimal crypto performance. This essentially will increase
the crypto performance on the secure domain. The crypto
functionality is used extensively by the current existing qseecom
client(s).
(4) Retain legacy support for QSEOS version 1.3.
In order for the existing applications to work with old QSEE image,
qseecom also supports the old mechanism (loading tzapp image via
pil). This was a requirement for existing products that are not
yet using the latest secure code.

The current split between this and the fiq debugger is awkward and does
not have any benefit (the interface between the two is also too simplistic).
The fiq debugger code itself needs a lot of refactoring, part of which
would be to split out some components that are arch indpendent.
So, for now, move this very small piece back into the fiq_debugger.

This driver allows userspace to access the data processing FPGAs on the
OVRO CARMA board. It has two modes of operation:
1) random access
This allows users to poke any DATA-FPGA registers by using mmap to map
the address region directly into their memory map.
2) correlation dumping
When correlating, the DATA-FPGA's have special requirements for getting
the data out of their memory before the next correlation. This nominally
happens at 64Hz (every 15.625ms). If the data is not dumped before the
next correlation, data is lost.
The data dumping driver handles buffering up to 1 second worth of
correlation data from the FPGAs. This lowers the realtime scheduling
requirements for the userspace process reading the device.

The PTI (Parallel Trace Interface) driver directs
trace data routed from various parts in the system out
through an Intel Penwell PTI port and out of the mobile
device for analysis with a debugging tool (Lauterbach or Fido).
Though n_tracesink and n_tracerouter line discipline drivers
are used to extract modem tracing data to the PTI driver
and other parts of an Intel mobile solution, the PTI driver
can be used independent of n_tracesink and n_tracerouter.
You should select this driver if the target kernel is meant for
an Intel Atom (non-netbook) mobile device containing a MIPI
P1149.7 standard implementation.

Topcliff PCH is the platform controller hub that is going to be used in
Intel's upcoming general embedded platform. All IO peripherals in
Topcliff PCH are actually devices sitting on AMBA bus. Packet hub is
a special converter device in Topcliff PCH that translate AMBA transactions
to PCI Express transactions and vice versa. Thus packet hub helps present
all IO peripherals in Topcliff PCH as PCIE devices to IA system.
Topcliff PCH has MAC address and Option ROM data.
These data are in SROM which is connected to PCIE bus.
Packet hub driver of Topcliff PCH can access MAC address and Option ROM data in
SROM via sysfs interface.

This driver adds support for the BMP085 digital pressure sensor from Bosch
Sensortec. It exposes a sysfs api to userspace where pressure and
temperature measurement results can be read from the pressure0_input and
temp0_input file. The chip is able to calculate the average of up to
eight samples to increase the accuracy. This feature can be controlled by
writing to the oversampling file.
The BMP085 digital pressure sensor can measure ambient air pressure and
temperature. Both values can be obtained from sysfs files. The pressure
is measured by reading from pressure0_input. Valid values range from
30000 to 110000 pascal with a resolution of 1 pascal (=0.01 millibar).
temp0_input holds the current temperature in degree celsius, multiplied by
10. This results in a resolution of a tenth degree celsius. Values range
from -400 to 850.
To increase the accuracy, this chip can calculate the average of 1, 2, 4
or 8 samples. This behavior is controlled through the oversampling sysfs
file. Two to the power of the value written to that file specifies how
many samples will be used. Valid values: 0..3.

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.
