2018-03-02iwlwifi: avoid collecting firmware dump if not loadedShaul Triebitz
Trying to collect firmware debug data while firmware is not loaded causes various errors (e.g. failing NIC access). This causes even a bigger issue if at that time the HW radio is off. In that case, when later turning the radio on, the Driver fails to read the HW (registers contain garbage values). (It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN bit is cleared on faulty NIC access - since the same behavior was seen in HW RFKILL toggling before setting that bit.)

2018-02-16iwlwifi: align timestamp cancel with timestamp startShaul Triebitz
Canceling the periodic timestamp work should be done in the opposite flow to where it was started. This also prevents from sending the MARKER command during the mac_stop flow - causing a false queue hang (FW is no longer there to send a response).

2017-12-20iwlwifi: runtime: sync FW and host clocks for logsMordechay Goodstein
For sync we send a marker cmd every <defined throughout debugfs> seconds. The trigger for getting gp2 clock values from the FW is set by writing to debugfs a periodic time in seconds, if value zero is written, only one request would be sent and the timer would be canceled. Also added a small infrastructure for debugfs runtime code. Signed-off-by: Mordechay Goodstein <mordechay.goodstein@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-12-05iwlwifi: mvm: make init_dbg effective only on failureLiad Kaufman
If FW loads without a problem, leaving init_dbg on can cause a confusion, since the user won't necessarily remember it is still turned on, and there are flows in which everything continues as usual, only without stopping the device after INIT, even if there is no FW assert. On 22000 HW, for instance, this causes a warning, since the paging is getting initialized twice. Solve the issue by making this module param effective only if the FW indeed asserts during INIT.

2017-10-25locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns ↵Mark Rutland
to READ_ONCE()/WRITE_ONCE() Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Paul E.

2017-07-21iwlwifi: mvm: defer setting IWL_MVM_STATUS_IN_HW_RESTARTJohannes Berg
A hardware/firmware error may happen at any point in time. In particular, it might happen while mac80211 is in the middle of a flow. We observed the following situation: * mac80211 is in authentication flow, in ieee80211_prep_connection() * iwlwifi firmware crashes, but no error can be reported at this precise point (mostly because the driver method is void, but even if it wasn't we'd just shift to a race condition) * mac80211 continues the flow, trying to add the AP station * iwlwifi has already set its internal restart flag, and so thinks that adding the station is part of the restart and already set up, so it uses the information that's supposed to already be in the struct This can happen with any flow in mac80211 and with any information we try to preserve across hardware restarts. To fix this, only set a new HW_RESTART_REQUESTED flag and translate that to IN_HW_RESTART once mac80211 actually starts the restart by calling our start() method. As a consequence, any mac80211 flow in progress at the time of the restart will properly finish (certainly with errors), before the restart is attempted.

2017-06-29iwlwifi: mvm: fix mac80211 queue trackingJohannes Berg
In the driver, we track which hardware queue is associated with which mac80211 "hw_queue", in order to be able to stop and wake it. When moving these bitmaps out of the queue_info structures, the type of the bitmap was erroneously changed from u32 to u8, presumably in order to save memory. Turns out that u32 isn't needed, because the highest queue we can ever tell mac80211 is always < 16, but a u16 definitely is needed, queues >=8 do happen. While at it, throw a BUILD_BUG_ON() into the place where we set the limit (mvm->first_agg_queue) and a warning when it actually gets put into the bitmap. The consequence of this bug is that full HW queues associated with such a too-high mac80211 number never stop higher layer queues when full, and thus would simply drop all packets that couldn't be enqueued to the hardware queue.

In case an assert happens on init flow, the current driver powers down the NIC, except if iwlmvm modparam init_dbg=1, and only on very specific flows. Extend this capability to cover most failure cases by keeping track of what init configurations have been completed. This way, we can allow NOT powering down the NIC, while making sure that when the driver is removed we don't try to free resources that haven't been allocated. (This can result in a kernel panic.)

When we want to stop the recording of the firmware debug and restart it later without reloading the firmware we don't need to resend the configuration that comes with host commands. Sending those commands confused the hardware and led to an NMI 0x66. Change the flow as following: * read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL) * clear those registers * wait for the hardware to complete its write to the buffer * get the data * restore the value of those registers (to restart the recording) For early start (where the configuration is already compiled in the firmware), we don't need to set those registers after the firmware has been loaded, but only when we want to restart the recording without having restarted the firmware.

This API replaces the complex NVM parsing of the iwlwifi module. Instead, we get all needed data from firmware. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-25iwlwifi: mvm: remove references to queue_info in new TX pathSara Sharon
Most of the fields aren't needed in new TX path. Enlarging the struct to 512 queues will consume a lot of memory. Remove all references to the struct in the new TX path. Move mac80211 queue mapping outside, since it will be needed per queue for TVQM mode. Add warning in paths that shouldn't be hit.

2017-04-25iwlwifi: mvm: make iwl_run_unified_mvm_ucode() staticJohannes Berg
There's no need to have iwl_run_unified_mvm_ucode() be exposed to other parts of the code since the logic to pick it over the normal code in iwl_run_init_mvm_ucode() can just be done in that function itself.

2017-04-19iwlwifi: mvm: support init extended commandSara Sharon
When we load firmware in extended mode (as we do by default for now) driver should send a command what kind of commands ucode should stop and wait for before proceeding with phy calibrations. Support this command. Currently we only do NVM access - so mark this bit only. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-19iwlwifi: mvm: add GEO_TX_POWER_LIMIT cmd for geographic tx power tableHaim Dreyfuss
To utilize the maximum allowed tx power, an additional table was added to the BIOS. The table consists of up to seven different regions (currently only three are in use). Each region contains per band: 1. Maximum allowed tx power on the band. 2. Tx power offset for chain A. 3. Tx power offset for chain B. On init flow driver reads this table by means of ACPI and passes it to the firmware with GEO_TX_POWER_LIMIT cmd. The firmware will use this table to enhance tx power with the offset in the relevant table as well as verifying it does not violate the maximum allowed tx power.

2017-04-19iwlwifi: mvm: prepare for station count changeSara Sharon
In a000 devices we will support up to 32 stations. The max station define is used also for invalid station marking which makes finding usages of actual maximum station pretty hard to sort through - change it to be a different define in order to make future changes easier. Use also ARRAY_SIZE intead of define when possible. Do not move yet to 32 stations until firmware do it though.
