2021-12-21iwlwifi: mvm: always store the PPAG table as the latest version.Miri Korenblit1-30/+26
In case of a conflict between BIOS version and FW version of the PPAG table - the values arrive in the FW in the wrong places. This happens because we're storing the table in different structures depending on the BIOS version, not on the FW version, and so the FW doesn't get what it expect to. Always store the table in a v2 structure (which is a superset of v1 and v0). Also store the table in a structured way and in it's own structure, rather then storing it in the ppag command structure, similarly to the WRDS, EWRD and WGDS tables.

2021-12-21iwlwifi: don't pass actual WGDS revision number in table_revisionLuca Coelho1-5/+13
The FW API for PER_CHAIN_LIMIT_OFFSET_CMD is misleading. The element name is table_rev, but it shouldn't actually contain the table revision number, but whether we should use the South Korea scheme or not. Fix the driver so that we only set this value to either 0 or 1. It will only be 1 (meaning South Korea) if the ACPI WGDS table revision is 1.

2021-12-21iwlwifi: mvm: Increase the scan timeout guard to 30 secondsIlan Peer1-1/+1
With the introduction of 6GHz channels the scan guard timeout should be adjusted to account for the following extreme case: - All 6GHz channels are scanned passively: 58 channels. - The scan is fragmented with the following parameters: 3 fragments, 95 TUs suspend time, 44 TUs maximal out of channel time. The above would result with scan time of more than 24 seconds. Thus, set the timeout to 30 seconds.

2021-12-07iwlwifi: support 4-bits in MAC step valueMike Golant1-7/+3
We have a MAC component (which is inside the SoC) and it has several different HW steps. 3 bits used to be enough but now we need 4-bits to represent all the different steps. Properly support 4-bits in the MAC step value by refactoring all the current handling of the MAC step/dash. Already from family 8000 and up the dash (bits 0-1) no longer exists and the step (until 8000 bits 2-3) consists of the dash bits as well. To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step into the trans struct. In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro combining the 2 (this way we don't need shifting or anything else.)

2021-12-07iwlwifi: mvm: synchronize with FW after multicast commandsJohannes Berg1-0/+17
If userspace installs a lot of multicast groups very quickly, then we may run out of command queue space as we send the updates in an asynchronous fashion (due to locking concerns), and the CPU can create them faster than the firmware can process them. This is true even when mac80211 has a work struct that gets scheduled. Fix this by synchronizing with the firmware after sending all those commands - outside of the iteration we can send a synchronous echo command that just has the effect of the CPU waiting for the prior asynchronous commands to finish. This also will cause fewer of the commands to be sent to the firmware overall, because the work will only run once when rescheduled multiple times while it's running.

2021-12-07iwlwifi: mvm: fix delBA vs. NSSN queue sync raceJohannes Berg2-1/+14
If we happen to decide an NSSN queue sync (IWL_MVM_RXQ_NSSN_SYNC) for some remaining packets that are still on the queue, but just after we've decided to do a delBA (which causes its own queues sync with IWL_MVM_RXQ_NOTIF_DEL_BA) we can end up with a sequence of events like this: CPU 1 CPU 2 remove BA session with baid N send IWL_MVM_RXQ_NOTIF_DEL_BA send IWL_MVM_RXQ_NSSN_SYNC get IWL_MVM_RXQ_NOTIF_DEL_BA get IWL_MVM_RXQ_NOTIF_DEL_BA get IWL_MVM_RXQ_NSSN_SYNC complete IWL_MVM_RXQ_NOTIF_DEL_BA remove N from baid_map[] get IWL_MVM_RXQ_NSSN_SYNC WARN_ON(!baid_map[N]) Thus, there's a race that leads in hitting the WARN_ON, but more importantly, it's a race that potentially even results in a new aggregation session getting assigned to baid N. To fix this, remove the WARN_ON() in the NSSN_SYNC case, we can't completely protect against hitting this case, so we shouldn't be warning. However, guard ourselves against BAID reuse by doing yet another round of queue synchronization after the entry is removed from the baid_map, so that it cannot be reused with any in-flight IWL_MVM_RXQ_NSSN_SYNC messages.
