* iwlwifi: add support for 9000 HW B-step NICsLiad Kaufman2017-04-111-6/+13
| | | | | | | | Once we remove support for A-step, we'll be able to clean the code back again. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: be more verbose about needed firmwareLuca Coelho2017-04-111-4/+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>
* lib/vsprintf.c: remove %Z supportAlexey Dobriyan2017-02-281-8/+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.

* iwlwifi: remove unnecessary cfg element in iwl_drvLuca Coelho2017-02-061-12/+10Star
| | | | | | | | 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>
* iwlwifi: remove unnecessary argument to iwl_drv_start()Luca Coelho2017-02-061-3/+2Star
| | | | | | | | | 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>

* iwlwifi: enlarge number of ucode sectionsSara Sharon2017-01-261-7/+24
| | | | | | | | | | | | The maximum number of firmware sections is now 32 instead of 16 for a000 devices. Set the appropriate define. Avoid out of bounds access in case there are more sections than the maximum set by driver. Make the driver extensible to FW size changes by allocating the section memory dynamically.

* iwlwifi: allow memory debug TLV to specify the memory typeJohannes Berg2017-01-261-0/+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.

* iwlwifi: mvm: accept arbitrary memory dump TLVsJohannes Berg2017-01-231-35/+22Star
| | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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.
