2017-11-03iwlwifi: remove dead code for internal devices onlyEmmanuel Grumbach1-6/+0
We had a bunch of code that was relevant for internal devices only. Those devices are now being depreceated. Kill all the now unneeded code. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-08-24Merge git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers.gitKalle Valo1-2/+3
Stephen Rothwell reported quite a few conflicts in iwlwifi between wireless-drivers and wireless-drivers-next. To avoid any problems later in other trees merge w-d to w-d-next to fix those conflicts early.
2017-08-18iwlwifi: Demote messages about fw flags size to infoJoão Paulo Rechi Vita1-6/+6
These messages are not reporting a real error, just the fact that the firmware knows about more flags than the driver. Currently these messages are presented to the user during boot if there is no bootsplash covering the console, even when booting the kernel with "quiet". Demoting it to the warn level helps having a clean boot process. Signed-off-by: João Paulo Rechi Vita <jprvita@endlessm.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-08-01iwlwifi: fix fw_pre_next_step to apply also for C stepHaim Dreyfuss1-2/+3
C step NICs should use the latest FW (currently B step). Correct the condition to make C step NICs advanced its default FW name to the latest one. Also rename _next_ to b_or_c to avoid confusion.

2017-06-29iwlwifi: create new subdirectory for FW interactionJohannes Berg1-1/+1
There's a lot of mvm code that really should be more generic and part of the iwlwifi module. Start by making a place to keep such code - in the new "fw" subdirectory - and already move the firmware related header files there.

2017-06-29iwlwifi: unify external & internal modparam namesJohannes Berg1-6/+6

2017-06-02iwlwifi: Add fw_name_pre_rf_next_step to support different rf stepsHaim Dreyfuss1-0/+4
Integrated chip may have different HW and RF steps. Currently, the driver supports only different HW steps. Add logic to support different RF steps enables combining different HW and RF steps.

2017-04-25iwlwifi: remove module loading failure messageJohannes Berg1-1/+1
When CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, iwlwifi crashes when the opmode module cannot be loaded, due to completing the completion before using drv->dev, which can then already be freed. Fix this by removing the (fairly useless) message. Moving the completion later causes a deadlock instead, so that's not an option.

2017-04-25iwlwifi: don't leak memory on allocation failureJohannes Berg1-6/+7
If we fail to allocate the small chunk of memory for the pieces of the firmware file, we leak the whole firmware image instead... Since the allocation failure is really unlikely, just bail out at that point instead. Remove the error message at the label since we now (and actually have been) use it for various reasons.

2017-04-11iwlwifi: be more verbose about needed firmwareLuca Coelho1-4/+19
If the supported firmware versions are not found, we currently only print "no suitable firmware found". This is not very informative for the user trying to find the correct version to use. Improve this by printing the exact firmware name(s) the driver supports and pointing to the git repository where they can be found. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-02-28lib/vsprintf.c: remove %Z supportAlexey Dobriyan1-8/+8
Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

2017-02-06iwlwifi: remove unnecessary cfg element in iwl_drvLuca Coelho1-12/+10
The iwl_drv structure contains trans which already contains cfg, so storing cfg separately in iwl_drv is redundant. Remove it and access trans->cfg instead. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-02-06iwlwifi: remove unnecessary argument to iwl_drv_start()Luca Coelho1-3/+2
When iwl_drv_start() is called, trans->cfg must already be set, so there's no need to pass cfg separately, since it can be accessed directly from trans->cfg. Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-01-31iwlwifi: alloc memory dynamically also for DVMSara Sharon1-0/+26

The maximum number of firmware sections is now 32 instead of 16 for a000 devices. Set the appropriate define.

2017-01-26iwlwifi: allow memory debug TLV to specify the memory typeJohannes Berg1-0/+12
Due to some new features and changes, the firmware file will now specify what type of memory to dump, in upper 8 bits of the type field of the TLV. Parse it (types we don't understand are errors) and teach the code to dump periphery memory.

2017-01-24iwlwifi: mvm: accept arbitrary memory dump TLVsJohannes Berg1-35/+22
There's no reason to be validating the memory dump types, or checking them for duplication, or anything, since we really just pass them through from the TLV to the dump. Thus, change the way we handle memory dump TLVs to let the driver just blindly use anything specified there, dumping it into the memory dump output file. This makes the system extensible without driver changes. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2016-07-01iwlwifi: advertise maximal MPDU length when Rx MQ is supportedEmmanuel Grumbach1-1/+2
The new hardware that supports multiple queue also de-aggregates A-MSDUs. This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K. Setting the amsdu_size module parameter to 4K will limit the A-MSDU on 9000 as well.

In commit 97f95c93c8ed ("iwlwifi: remove support for fw older than -16.ucode") we accidentally changed the fw version reading code for DVM devices. The code intended to remove the old fw version API, because all MVM firmwares version 16 and above that we support don't use it anymore. But DVM devices still use the old FW API. Fix that by bringing the code back in.

_UCODE_API_OK was a intermediate version between MIN and MAX. If a user had a firmware below _OK but above _MIN, the driver would work but the user would get a warning in the kernel log telling him to update his firmware.

2015-12-16iwlwifi: expose fw usniffer mode to more utilitiesGolan Ben-Ami1-5/+6
Today, in order to configure fw in usniffer mode, the ucode must have the corresponding tlv, which is revealed to the driver while parsing the ucode. Expose the mode of the usniffer to other utilities in the driver (other than the ucode parser) by passing back a pointer to the value. This can be very useful for allowing configuring the fw dbg data using an external configuration file, because this configuration depends on the fw usniffer mode.
