2019-02-14iwiwifi: mvm: Fix FW scan concurrency support assumptionsIlan Peer2-5/+10
- The FW supports up to 4 concurrent scans, so adjust the definitions accordingly. - Only a single periodic scan is supported, so enforce it in the code. Signed-off-by: Ilan Peer <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-02-14iwlwifi: mvm: add a debug_enable opShahar S Matityahu5-5/+19
D3 debug data is disabled by default. Currently it is done by tampering the dump mask. Add an operation that will allow this to be changed without recompilation. Signed-off-by: Shahar S Matityahu <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

2019-02-14iwlwifi: mvm: add support for 32kHz external clock indicationHaim Dreyfuss6-9/+74
In low power modes, the chip clock source for platform integrated devices is 32kHz. It is generated internally and supplied by a crystal oscillator. However using a 32kHz sourced from crystal oscillator has high power penalty. There is an option to get an external 32kHz clock from the platform. Past experience shows that the reliability is platform dependent, i.e. on some platforms it works good and on other it doesn’t. Working from external clock will save 0.5 mW in sleep state, from overall 1.8mW that we have today, i.e. almost 30%. Each OEM can enable or disable the use of the external 32kHz clock by setting a BIOS configuration. In case the OEM configured to use 32kHz external clock the driver will pass this indication to the FW. Signed-off-by: Haim Dreyfuss <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-02-14iwlwifi: pcie: fix TX while flushingSara Sharon3-2/+34
When flushing TX queues no new TX should go into the system. However, in the following scenario we get TX: 1. Queues are stopped and there are packets in overflow queue 2. Station is removed and flush begins 3. Flush empties space, and reclaim path TXes SKB from overflow queue. Note that the fact the queues are stopped during the process doesn't matter - the packet will be TXed since the TX path doesn't care if TX queues are stopped or not, just if there is space in the queue, which there is, since we just freed a packet. A fix here is rather complicated, since the flow is very racy. Change code not to warn if we are TXing from overflow TX. In case there is TX from both overflow TX and TX path we will miss a warning we optimally had, but we can live with that. Make sure we don't return before overflow queue is empty, otherwise we will think queues are empty, but they will be refilled, resulting with assert.

2019-02-14iwlwifi: mvm: Fix possible NULL pointer dereferenceAvraham Stern1-1/+1
iwl_mvm_te_clear_data() is called for cleanup in case sending the HOT_SPOT_CMD failed. However, in case sending the command caused a fw error and restart (e.g. if the command is not supported) then the te_data pointer may no longer be valid, which leads to a NULL pointer dereference. Fix it by checking that the te_data pointer is not NULL before dereferencing it. Signed-off-by: Avraham Stern <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-02-14iwlwifi: do not fail on large amount of channelsShaul Triebitz1-3/+3
Until supporting UHB (ultra high band) channels for devices AX210, do not fail if number of channels reported by firmware is greater than NL80211_MAX_SUPP_REG_RULES. The Driver in that case will use only the non-UHB channels. Signed-off-by: Shaul Triebitz <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-02-14iwlwifi: add FW recovery flowMordechay Goodstein9-0/+118
Add new API and TLV for the ability to send commands in the beginning and end of reset flow. The full flow of recovery is: 1. While loading FW, get address (from the TLV) of target buffer to read in case of reset 2. If an error/assert happens read the address data from step 1. 3. Reset the HW and load the FW. 4. Send the data read in step 2. 5. Add station keys 6. Send notification to FW that reset flow is done. The main use of the recovery flow is for support in PN/SN recovery when offloaded Signed-off-by: Mordechay Goodstein <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

2019-02-14iwlwifi: dbg_ini: rewrite trigger flow and align to FW API changesShahar S Matityahu5-49/+107
Trigger field ignore_default was changed to override_trig. The first byte of the field indicates the driver to override existing configuration or keep the previous one The second byte of the field indicated the driver to replace the regions of the previous trigger or to append new regions to it. Change the way the active triggers are maintained to support trigger override in different apply points. Do this by making a trigger that updates at runtime by the triggers that are being used in the different apply points. In case of an assert, the driver does not reconfigure the triggers and uses the old configuration which leads to undefined behavior. Solve this by clearing the triggers in assert recovery flow.

2019-02-14iwlwifi: receive umac and lmac error table addresses from TLVsShahar S Matityahu9-28/+107
TLV 54 holds umac debug related addresses. TLV 55 holds lmac debug related addresses. These TLVs aim to replace the alive notification data in the future. Parse and keep error table addresses received from the TLVs for both lmac and umac and use these addresses instead of the pointer received from alive notification.

2019-02-14iwlwifi: pcie: fix emergency pathSara Sharon1-3/+8
Allocator swaps the pending requests with 0 when it starts working. This means that relying on it n RX path to decide if to move to emergency is not always a good idea, since it may be zero, but there are still a lot of unallocated RBs in the system. Change allocator to decrement the pending requests on real time. It is more expensive since it accesses the atomic variable more times, but it gives the RX path a better idea of the system's status.

2019-02-04iwlwifi: dbg_ini: remove redundant dram buffer allocationShahar S Matityahu4-48/+85
There are several flows in that can cause redundant allocation. In case the driver reaches the maximum amount of blocks allowed, it allocates the buffer and only then checks if it reached the maximum amount of blocks and return without freeing the buffer, causing a memory leak. Solve this by moving the check of the amount of buffers being used before the allocation. In case there was an assert, the apply points are being reused, causing that for each assert, the driver allocates a new redundant buffer. Solve this by adding a new is_alloc field to indicate if the driver already allocated memory for the requested buffer. Also, split iwl_fw_dbg_buffer_allocation function into iwl_fw_dbg_buffer_allocation and iwl_fw_dbg_buffer_apply to increase the clearity of the flow.
