From: Emmanuel Grumbach @ 2014-12-02 18:10 UTC (permalink / raw)
To: linux-wireless; +Cc: Johannes Berg, Emmanuel Grumbach
From: Johannes Berg <johannes.berg@intel.com>
The firmware file-format is described in iwl-fw-file.h, while the
internal handling structures and functions are in iwl-fw.h.
Fix the separation between the files by moving file format
definitions to iwl-fw-file.h.
Also add a missing description for a kernel-doc member, and it's
not needed to include iwl-fw-file.h again from the code (thanks
to Liad Kaufman).

From: Luciano Coelho <luciano.coelho@intel.com>
Query the firmware for scan offload matches when waking up in order to
report net detect as the reason for the wake up.
This requires a new command API to be implemented. Additionally,
remove some net detect command entries that are not valid anymore.

To: linux-wireless; +Cc: Luciano Coelho, Emmanuel Grumbach
From: Luciano Coelho <luciano.coelho@intel.com>
Add SSID information to the net-detect indication to userspace. Fetch
the matched profiles from the firmware in order to find the correct
SSIDs in the profiles that matched.
Since the net-detect information is stored in cfg80211, and in theory
it could change while we are waking up and reading the matched
profiles, we need to save it when we enter D3 so it is available
during resume.

Add the channels on which there was a match for every match reported
by the firmware. The firmware reports the channels as indices to the
array of channels that was passed in the scheduled scan request, so we
need to save the array when entering D3 to make sure it is available
when we resume.

7265D are new devices that should always have a new NVM
(at least 0x0c11). The firmware has issues with older
versions of the NVM which are not and will not be available
to the common mortals.

Adds all FH registers between FH_MEM_UPPER_BOUND and
FH_MEM_LOWER_BOUND (which should be readable to the driver)
to the dump data when it is collected.

From: Liad Kaufman <liad.kaufman@intel.com>
In 8000 B-step the FW file has changed, but by the time we
know the HW step, the FW file is already requested.
This patch defaults 8000 family to B-step if no HW step is
detected in time. When it can it checks what HW step it
really is (in 8000 family) and if it isn't B-step, the FW
file is released and the A-step file is requested.

Since the commit below, iwldvm sends the FLUSH command to
the firmware. All the devices that use iwldvm have a
firmware that expects the _v3 version of this command,
besides 5150.
5150's latest available firmware still expects a _v2 version
of the FLUSH command.
This means that since the commit below, we had a mismatch for
this specific device only.
This mismatch led to the NMI below:
Loaded firmware version: 8.24.2.2

Interoperability issues were identified and root caused to
the Smart Fifo watermarks. These issues arose with
NetGear R7000. Fix this.

Sometimes there is a need to configure some registers for
setting some FW properties, such as the FW monitor mode
(internal/external). This patch supports setting this for
PCIe mode.

From: Liad Kaufman <liad.kaufman@intel.com>
Until this patch, dumping the monitor data could be done only
for PCIe external (DRAM) mode in 7000 HW family. This patch
allows to pull the monitor data also on other families, and
also to pull the monitor data if an internal buffer is used.

(in addition to the operational images and the TLVs).
The driver can load the usniffer image if debug
configuration tells it to.
