2018-12-20iwlwifi: mvm: d3: use struct_size() in kzalloc()Gustavo A. R. Silva1-4/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This issue was detected with the help of Coccinelle.

2018-12-20iwlwifi: mvm: clean up SSN incrementationSara Sharon1-6/+4
Sometimes, due to SCD bug, we need to start the queue with an higher SSN. The queue allocation function currently increments the SSN in the packet itself, but it is pointless, since this value is overridden later by iwl_mvm_tx_mpdu with the value from mvmsta->tid_data[tid].seq_number. Updating tid data is sufficient. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2018-12-20iwlwifi: pcie: lock txq a bit later in reclaim codeSara Sharon1-1/+2
In reclaim code, we don't need to take the queue lock for waking the queue. The code section is executed only when the tx path is stopped, and since the reclaim path is not executed in parallel to itself, no one can update the queue pointers, and accessing them is safe without a lock.

2018-12-20iwlwifi: make MVM and DVM depend on MAC80211Luca Coelho1-1/+3

2018-12-20iwlwifi: mvm: fix setting HE ppe FW configNaftali Goldstein2-2/+8
The FW expects to get the ppe value for each NSS-BW pair in the same format as in the he phy capabilities IE, which means that a value of 0 implies ppe should be used for BPSK (mcs 0). If there are no PPE thresholds in the IE, or if for some NSS-RU pair there's no threshold set for it (this could happen because it's a variable-sized field), it means no PPE should not be used for that pair, so the value sent to FW should be 7 which corresponds to "none".

2018-12-20iwlwifi: mvm: remove dead codeSara Sharon1-6/+0
In iwl_mvm_tx_skb_non_sta(), in case of managed interface, the AP station was supposed to be used for multicast frames instead of the auxiliary station to avoid frames possibly sent to an absent P2P GO. However, when moving to DQA mode, this was broken as no valid queue was assigned. This is fixed by a recent patch that directs all non-offchannel traffic to ap station earlier in the TX path. However, the broken, and now dead code, remained. Remove it.

2018-12-14iwlwifi: mvm: add L-SIG length to radiotapShaul Triebitz1-36/+60
We may have the L-SIG length depending on the phy_data info type; add it to radiotap when we do. Move getting the phy_data out one layer up and the info type into it so we can use this data more generically. We need to call the iwl_mvm_rx_he() function for other reasons as well, so can't just combine all of that into something like iwl_mvm_parse_phy_data().

2018-12-14iwlwifi: mvm: change PHY data RX for HE radiotapShaul Triebitz2-261/+296
The firmware changed the PHY data API, so follow suit. Some data is now available even for HT/VHT frames, so the info type in the metadata was changed. This change isn't backwards compatible, but 1) the firmware with the old API was never released; 2) the only overlap in the info type field is from the old type of TB to the new of HT, so this basically just means that with older FW and newer driver the data will be considered missing. While at it, remove the extra code to set the LTF syms corresponding to the streams and use the data from the device instead - we don't really need this in any case other than when we have it from the device. As the new API gives use the spatial reuse 1-4 fields for trigger-based PPDUs, also expose that to radiotap.

2018-12-14iwlwifi: pcie: fix erroneous printSara Sharon1-5/+5
When removing the driver, the following flow can happen: 1. host command is in progress, for example at index 68. 2. RX interrupt is received with the response. 3. Before it is processed, the remove flow kicks in, and calls iwl_pcie_txq_unmap. The function cleans all DMA, and promotes the read pointer to 69. 4. RX thread proceeds with the processing, and is calling iwl_pcie_cmdq_reclaim, which will print this error: iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0), index 4 is out of range [0-256] 69 69. Detect this situation, and avoid the print. Change it to warning while at it, to make such issues more noticeable in the future.

2018-12-14iwlwifi: mvm: force TCM re-evaluation on TCM resumeAvraham Stern1-0/+14
When traffic load is not low or low latency is active, TCM schedules re-evaluation work so in case traffic stops TCM will detect that traffic load has become low or that low latency is no longer active. However, if TCM is paused when the re-evaluation work runs, it does not re-evaluate and the re-evaluation work is no longer scheduled. As a result, TCM will not indicate that low latency is no longer active or that traffic load is low when traffic stops. Fix this by forcing TCM re-evaluation when TCM is resumed in case low latency is active or traffic load is not low.

2018-12-14iwlwifi: remove all unnecessary occurrences of nvm_calib_verLuca Coelho4-31/+0
Now that nvm_calib_ver is not checked in opmodes other than dvm, we can remove it from all irrelevant configurations. Signed-off-by: Luca Coelho <[email protected]>
2018-12-14iwlwifi: move iwl_nvm_check_version() into dvmLuca Coelho4-23/+22
This function is only half-used by mvm (i.e. only the nvm_version part matters, since the calibration version is irrelevant), so it's pointless to export it from iwlwifi. If mvm uses this function, it has the additional complexity of setting the calib version to a bogus value on all cfg structs. To avoid this, move the function to dvm and make a simple comparison of the nvm_version in mvm instead. Signed-off-by: Luca Coelho <[email protected]>
2018-12-14iwlwifi: remove useless NVM_HW_SECTION_NUM_FAMILY_* macrosLuca Coelho4-11/+4
These macros are useless because each one of them is used only once and the element they are assigned to is already pretty clear about what they mean, "nvm_hw_section_num". Signed-off-by: Luca Coelho <[email protected]>

Using OTP_LOW_IMAGE_SIZE_FAMILY_8000/9000/22000 only obfuscates the actual values, since these 3 are the same. Redefine the values per size so it's easier to understand and compare the different configurations. Signed-off-by: Luca Coelho <[email protected]>
