Add an initial implementation of runtime power management (RTPM) for PCI devices. With this patch, RTPM is only used when wifi is off (i.e. the wifi interface is down). This implementation is behind a new Kconfig flag, IWLWIFI_PCIE_RTPM. Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

This driver uses the kernel's mac80211 subsystem.
|
|
|
|
In order to use this driver, you will need a firmware
|
|
image for it. You can obtain the microcode from:
|
|
|
|
<http://wireless.kernel.org/en/users/Drivers/iwlwifi>.
|
|
|
|
The firmware is typically installed in /lib/firmware. You can
|
|
look in the hotplug script /etc/hotplug/firmware.agent to
|
|
determine which directory FIRMWARE_DIR is set to when the script
|
|
runs.
|
|
|
|
If you want to compile the driver as a module ( = code which can be
|
|
inserted in and removed from the running kernel whenever you want),
|
|
say M here and read <file:Documentation/kbuild/modules.txt>. The
|
|
module will be called iwlwifi.

Say Y here to enable default bcast filtering configuration.

Enabling broadcast filtering will drop any incoming wireless
|

broadcast frames, except some very specific predefined

|
patterns (e.g. incoming arp requests).
|
|

If unsure, don't enable this option, as some programs might

expect incoming broadcasts for their normal operations.

---help---
|
|
This option will enable debug tracing output for the iwlwifi drivers
|
|
|
|
This will result in the kernel module being ~100k larger. You can
|
|
control which debug output is sent to the kernel log by setting the
|
|
value in
|
|
|
|
/sys/module/iwlwifi/parameters/debug
|
|
|
|
This entry will only exist if this option is enabled.
|
|
|
|
To set a value, simply echo an 8-byte hex value to the same file:
|
|
|
|
% echo 0x43fff > /sys/module/iwlwifi/parameters/debug
|
|
|
|
You can find the list of debug mask values in:
|
|
drivers/net/wireless/iwlwifi/iwl-debug.h
|
|
|
|
If this is your first time using this driver, you should say Y here

as the debug information can assist others in helping you resolve
|

any problems you may encounter.

help
|
|
Say Y here to trace all commands, including TX frames and IO
|
|
accesses, sent to the device. If you say yes, iwlwifi will
|
|
register with the ftrace framework for event tracing and dump
|
|
all this information to the ringbuffer, you may need to
|
|
increase the ringbuffer size. See the ftrace documentation
|
|
for more information.
|
|
|
|
When tracing is not enabled, this option still has some
|
|
(though rather small) overhead.
|
|
|
|
If unsure, say Y so we can help you better when problems
|
|
occur.
