| * mac80211: populate debugfs only after cfg80211 initJohannes Berg2020-04-245-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When fixing the initialization race, we neglected to account for the fact that debugfs is initialized in wiphy_register(), and some debugfs things went missing (or rather were rerooted to the global debugfs root). Fix this by adding debugfs entries only after wiphy_register(). This requires some changes in the rate control code since it currently adds debugfs at alloc time, which can no longer be done after the reordering.

* | iwlwifi: fix WGDS check when WRDS is disabledLuca Coelho2020-04-212-16/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the reference BIOS implementation, WRDS can be disabled without disabling WGDS. And this happens in most cases where WRDS is disabled, causing the WGDS without WRDS check and issue an error. To avoid this issue, we change the check so that we only considered it an error if the WRDS entry doesn't exist. If the entry (or the selected profile is disabled for any other reason), we just silently ignore WGDS.

* | iwlwifi: mvm: fix inactive TID removal return value usageJohannes Berg2020-04-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The function iwl_mvm_remove_inactive_tids() returns bool, so we should just check "if (ret)", not "if (ret >= 0)" (which would do nothing useful here). We obviously therefore cannot use the return value of the function for the free_queue, we need to use the queue (i) we're currently dealing with instead.

* | iwlwifi: mvm: limit maximum queue appropriatelyJohannes Berg2020-04-212-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to some hardware issues, queue 31 isn't usable on devices that have 32 queues (7000, 8000, 9000 families), which is correctly reflected in the configuration and TX queue initialization. However, the firmware API and queue allocation code assumes that there are 32 queues, and if something actually attempts to use #31 this leads to a NULL-pointer dereference since it's not allocated. Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also add some code to catch this earlier in the future, if the configuration changes perhaps.

* | iwlwifi: pcie: indicate correct RB size to deviceJohannes Berg2020-04-211-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the context info, we need to indicate the correct RB size to the device so that it will not think we have 4k when we only use 2k. This seems to not have caused any issues right now, likely because the hardware no longer supports putting multiple entries into a single RB, and practically all of the entries should be smaller than 2k. Nevertheless, it's a bug, and we must advertise the right size to the device. Note that right now we can only tell it 2k vs. 4k, so for the cases where we have more, still use 4k. This needs to be fixed by the firmware first.

* | iwlwifi: pcie: actually release queue memory in TVQMJohannes Berg2020-04-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iwl_trans_pcie_dyn_txq_free() function only releases the frames that may be left on the queue by calling iwl_pcie_gen2_txq_unmap(), but doesn't actually free the DMA ring or byte-count tables for the queue. This leads to pretty large memory leaks (at least before my queue size improvements), in particular in monitor/sniffer mode on channel hopping since this happens on every channel change. This was also now more evident after the move to a DMA pool for the byte count tables, showing messages such as BUG iwlwifi:bc (...): Objects remaining in iwlwifi:bc on __kmem_cache_shutdown() This fixes https://bugzilla.kernel.org/show_bug.cgi?id=206811.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A couple of SoCs, which can be recognized by PCI device IDs 0xA0F0 and 0x43F0, need a longer wait for the xtal to stabilize. To handle this, add a new trans_cfg structure for Qu devices with a larger xtal_latency value and apply them to the devices recognized by these IDs. Also add a flag that allows us to inform the FW that the low latency xtal should be used. Change-Id: I8a14c6af45ea14d8e7f1ef38a589158f38d0c0ea Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

The device type bit remains the same (because we only had 0 and 1 anyway), but when using v1 we can't set any other bits, because that would change the integer. Other than that, the struct remains the same and the driver can set the device_type bit in both cases, but it can only set the low_latency bit if VER_2 is used.

By moving them to the trans_cfg, we avoid duplicating the large cfg structs for small pieces of data (sometimes a single boolean). This will also allow us to make more decisions based on, for instance, the SoC type in used. The trans_cfg concept changes a bit, because previously it was used only to boot the device before reading further characteristics and now it also contains more data that is associated with the device ID.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new region type that allows us to dump the PCI config space. This is mostly the same as dumping a memory region, but reading from the device's config space instead. In order to make this generic and independent of the trans type, we make a function called iwl_dump_ini_config_iter() that calls a new op in the transport to read its config space.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices require longer time to stabilize the power and XTAL. This is especially true for devices integrated in the SoC. Add support for a new firmware API that allows the driver to set the latency value accordingly.

Hence the current implementation of amsdu list based processing after all the subframes of amsdu are received (since all msdu's for a pdev are received in same reo dest ring), is not applicable here and hence is replaced with per msdu based handling as these subframes can be received in different reo dest rings. Also, as some of the rx descriptor fields might be valid only for the first msdu (for ex. received 80211 header, encryption type, etc), it might not be useful now as we cannot sync between different subframes received in different rings. Hence do not rely on those fields and replace them with fieds valid only on per msdu descriptors. Also cache other details such as encryption type for a peer so that it can be reused when a packet is received from it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation of pdev based reo destination ring selection is replaced by hash based ring selection so as to ensure all the available rings are utilized for better performance. The 4 reo destination rings are selected by the HW based on the hash value computed from the received packet based on the 5 tuple {ip src/ip dst/src port/dst port/protocol}. Out of the 32 hash values used by the hw, the driver assigns 8 values per reo destination ring to each of the 4 reo destination rings.
