2017-08-09iwlwifi: remove references to unsupported HWLuca Coelho1-7/+1
There are still some references to 3945 and 4965 HW, which were never supported in iwlwifi. These references were inherited from a previous project and are irrelevant here. Additionally, remove some irrelevant references to 5100 HW. Remove all these. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

I'm submitting this unusally late in the cycle as my vacation postponed this. But even if this is late there's not still that much new features, mostly cleanup or fixes.

2017-07-21iwlwifi: dvm: prevent an out of bounds accessEmmanuel Grumbach1-1/+1
iwlagn_check_ratid_empty takes the tid as a parameter, but it doesn't check that it is not IWL_TID_NON_QOS. Since IWL_TID_NON_QOS = 8 and iwl_priv::tid_data is an array with 8 entries, accessing iwl_priv::tid_data[IWL_TID_NON_QOS] is a bad idea. This happened in iwlagn_rx_reply_tx. Since iwlagn_check_ratid_empty is relevant only to check whether we can open A-MPDU, this flow is irrelevant if tid is IWL_TID_NON_QOS. Call iwlagn_check_ratid_empty only inside the if (tid != IWL_TID_NON_QOS) a few lines earlier in the function.

2016-07-06iwlwifi: decouple PCIe transport from mac80211Johannes Berg1-0/+2
The PCIe transport needs to store two pointers in each TX SKB, and currently assumes mac80211's ieee80211_tx_info is present in the CB to do that. In order to remove that assumption, have the opmodes pass in the offset to where the pointers can be stored in the CB and use the offset in the PCIe code. To make the disentanglement complete, remove mac80211.h includes from everywhere in the generic iwlwifi code. This required adding an include of cfg80211.h in one place.

2016-07-01iwlwifi: advertise maximal MPDU length when Rx MQ is supportedEmmanuel Grumbach1-0/+1
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.

This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it.

2016-03-30iwlwifi: dvm: use alloc_ordered_workqueue()Eva Rachel Retuya1-1/+1
Use alloc_ordered_workqueue() to allocate the workqueue instead of create_singlethread_workqueue() since the latter is deprecated and is scheduled for removal. There are work items doing related operations that shouldn't be swapped when queued in a certain order hence preserve the strict execution ordering of a single threaded (ST) workqueue by switching to alloc_ordered_workqueue(). WQ_MEM_RECLAIM flag is not needed since the worker is not depended during memory reclaim.

2016-03-09iwlwifi: mvm: adapt the firmware assert log to new firmwareEmmanuel Grumbach1-4/+4
Newer firmware versions put different data in the memory which is read by the driver upon firmware crash. Just change the variable names in the code and the name of the data in the log that we print withouth any functional change. On older firmware, there will be a mismatch between the names that are printed and the content itself, but that's harmless. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2016-02-01iwlwifi: mvm: Do not switch to D3 image on suspendMatti Gottlieb1-2/+2
Currently when the driver is configured with wowlan parameters, and enters D3 mode, the driver switches the FW image to D3, and when it exists suspend, it reloads the D0 image. If the firmware supports the consolidation of the D0 & D3 images there is no need to load the D3 image on suspend, and no need to reload the D0 image on resume. Do not switch images on suspend / resume, for firmwares that support consolidated images.

2016-01-16include/linux/kernel.h: change abs() macro so it uses consistent return typeMichal Nazarewicz1-1/+1
Rewrite abs() so that its return type does not depend on the architecture and no unexpected type conversion happen inside of it. The only conversion is from unsigned to signed type. char is left as a return type but treated as a signed type regradless of it's actual signedness. With the old version, int arguments were promoted to long and depending on architecture a long argument might result in s64 or long return type (which may or may not be the same). This came after some back and forth with Nicolas. The current macro has different return type (for the same input type) depending on architecture which might be midly iritating. An alternative version would promote to int like so: #define abs(x) __abs_choose_expr(x, long long, \ __abs_choose_expr(x, long, \ __builtin_choose_expr( \ sizeof(x) <= sizeof(int), \ ({ int __x = (x); __x<0?-__x:__x; }), \ ((void)0)))) I have no preference but imagine Linus might. :] Nicolas argument against is that promoting to int causes iconsistent behaviour: int main(void) { unsigned short a = 0, b = 1, c = a - b; unsigned short d = abs(a - b); unsigned short e = abs(c); printf("%u %u\n", d, e); // prints: 1 65535 } Then again, no sane person expects consistent behaviour from C integer arithmetic. ;) Note: __builtin_types_compatible_p(unsigned char, char) is always false, and __builtin_types_compatible_p(signed char, char) is also always false.

2016-01-07iwlwifi: dvm: fix WoWLANEmmanuel Grumbach1-0/+3
My commit below introduced a mutex in the transport to prevent concurrent operations. To do so, it added a flag (is_down) to make sure the transport is in the right state. This uncoverred an bug that didn't cause any harm until now: iwldvm calls stop_device and then starts the firmware without calling start_hw in between. While this flow is fine from the device configuration point of view (register, etc...), it is now forbidden by the new is_down flag. This led to this error to appear: iwlwifi 0000:05:00.0: Can't start_fw since the HW hasn't been started and the suspend would fail.
