2019-04-03iwlwifi: set 512 TX queue slots for AX210 devicesShaul Triebitz3-3/+9
AX210 devices support 256 BA (256 MPDUs in an AMPDU). The firmware requires that the number of TFDs will be minimum twice as big as the BA size (2 * 256 = 512). Signed-off-by: Shaul Triebitz <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-04-03iwlwifi: mvm: use correct GP2 register address for 22000 familyAvraham Stern7-12/+23
The device time register address has changed for 22000 devices. Add a util function for getting the GP2 time and use the correct register address depending on the device family. Signed-off-by: Avraham Stern <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-04-03iwlwifi: dbg: fill radio registers data regardless of fifos data dumpingShahar S Matityahu1-2/+3
The driver calculates memory regions dump size, allocate memory and fills the data. The driver fills the radio registers data only if the memory size of the fifos is greater then zero, so in case the user masked out the fifos from the dump, the driver will skip filling the radio register data. Solve this by checking filling radio registers data independently from fifos data. Signed-off-by: Shahar S Matityahu <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-04-03iwlwifi: pcie: no need to check return value of debugfs_create functionsGreg Kroah-Hartman3-19/+6
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

2019-04-03iwlwifi: mvm: remove buggy and unnecessary hw_queue initializationJohannes Berg1-33/+3
After converting the driver to TXQs, it no longer has any reason to initialize vif->hw_queue/vif->cab_queue since it no longer sets the HW_QUEUE_CONTROL flag. Remove the code that initialized those, it was broken due to relying on an uninitialized stack value in used_hw_queues, as Colin reported.

2019-04-03iwlwifi: mvm: IBSS: use BE FIFO for multicastJohannes Berg1-1/+2
Back in commit 4d339989acd7 ("iwlwifi: mvm: support ibss in dqa mode") we changed queue selection for IBSS to be: if (ieee80211_is_probe_resp(fc) || ieee80211_is_auth(fc) || ieee80211_is_deauth(fc)) return IWL_MVM_DQA_AP_PROBE_RESP_QUEUE; if (info->hw_queue == info->control.vif->cab_queue) return info->hw_queue; return IWL_MVM_DQA_AP_PROBE_RESP_QUEUE; Clearly, the thought at the time must've been that mac80211 will select the hw_queue as the cab_queue, so that we'll return and use that, where we store the multicast queue for IBSS. This, however, isn't true because mac80211 doesn't implement powersave for IBSS and thus selects the normal IBSS interface AC queue (best effort). This therefore always used the probe response queue, which maps to the BE FIFO. In commit cfbc6c4c5b91 ("iwlwifi: mvm: support mac80211 TXQs model") we rethought this code, and as a consequence now started mapping the multicast traffic to the multicast hardware queue since we no longer relied on mac80211 selecting the queue, doing it ourselves instead. This queue is mapped to the MCAST FIFO. however, this isn't actually enabled/controlled by the firmware in IBSS mode because we don't implement powersave, and frames from this queue can never go out in this case. Therefore, we got queue hang reports such as https://bugzilla.kernel.org/show_bug.cgi?id=201707 Fix this by mapping the multicast queue to the BE FIFO in IBSS so that all the frames can go out.

2019-03-22iwlwifi: pcie: switch to correct RBD/CD layout for 22560Johannes Berg4-98/+13
The layout of the RBD (receive buffer descriptor) isn't quite right, the hardware ended up being implemented differently. Switch to the correct RBD layout. While at it, remove the now useless extra defines. Also, switch the CD (completion descriptor) to the right format, which is basically just a code cleanup because the only field we really used (rbid) is still in the same place. We may need fragmentation later if we ever want to use it. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-03-22iwlwifi: mvm: use dump worker during restart instead of sync dumpShahar S Matityahu4-23/+2
In restart flow, the driver requests HW restart from mac80211 and then mac80211 uses a worker to do the restart flow. In that flow a sync dump is performed. Instead, schedule the dump worker before requesting HW restart from mac80211. This approach simplifies the restart flow. Also, it is neeeded in order to differentiate between the handling of SW and HW errors in a future commit.
