2020-10-08iwlwifi: mvm: prepare roc_done_wk to work syncNathan Errera6-29/+26
As part of changes made to properly support auxiliary activities in CDB NICs, an aux sta will be added when using hot spot 2.0 and will need to be removed when roc flow is done. In order to do so, prepare the roc_done_wk to work synchronously as the rm_aux_sta is a SYNC command. Since now all of th iwl_mvm_flush_sta function are using it sync, removed the flag argument from the function.

2020-10-08iwlwifi: mvm: re-enable TX after channel switchSara Sharon2-6/+2
The FW relies on the re-enablement of the TX in order to know it can exit quiet mode. Currently in case of CSA with quiet mode, the quiet mode is never cancelled, resulting in a complete traffic hang.

2020-10-08iwlwifi: mvm: don't send RFH_QUEUE_CONFIG_CMD with no queuesLuca Coelho1-1/+8
If we have only a single RX queue, such as when MSI-X is not available, we should not send the RFH_QUEUEU_CONFIG_CMD, because our only queue is the same as the command queue and will be configured as part of the context info. Our code was actually trying to send the command with 0 queues, which caused UMAC assert 0x1D04. Fix that by not sending the command when we have a single queue.

2020-10-08mwifiex: fix double freeTom Rix1-0/+2
clang static analysis reports this problem: sdio.c:2403:3: warning: Attempt to free released memory kfree(card->mpa_rx.buf); ^~~~~~~~~~~~~~~~~~~~~~~ When mwifiex_init_sdio() fails in its first call to mwifiex_alloc_sdio_mpa_buffer, it falls back to calling it again. If the second alloc of mpa_tx.buf fails, the error handler will try to free the old, previously freed mpa_rx.buf. Reviewing the code, it looks like a second double free would happen with mwifiex_cleanup_sdio(). So set both pointers to NULL when they are freed.

2020-10-01ath11k: enable shadow register configuration and accessCarl Huang9-8/+194
To enable shadow register access, host needs to pass shadow register configuration to firmware via qmi message. Host also needs to update ring's HP or TP address to shadow register address. The write operation to shadow register will be forwarded to target register by hardware automatically, and the write operation to shadow register is permitted even when the target is in power save or sleep mode. Update the shadow config whenever power up happens. This feature is controlled by hw parameter supports_shadow_regs which is only enabled for QCA6390.

2020-10-01ath11k: read and write registers below unwindowed addressCarl Huang2-0/+42
For QCA6390, host can read and write registers below unwindowed address directly without programming the window register. For registers below bar0 + 4k - 32, host can read and write regardless of the power save state. Shadow registers are located below bar0 + 4K - 32. Before MHI power up, there is no need to wakeup MHI so ini_done is added to indicate it.

2020-10-01ath11k: debugfs: fix crash during rmmodCarl Huang1-4/+4
With QCA6390 when doing rmmod the kernel crashed. The reason was that the destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy() accidentally had swapped the debugfs directories and ath11k_debugfs_soc_destroy() was removing an already removed directory, which crashed the kernel. The source of confusion is badly named function and variable names. I think the best way to clean this up is actually to merge the corresponding functions, but that's for another patch. Let's first just fix the crash.

2020-10-01ath11k: add packet log support for QCA6390Carl Huang9-53/+166
Add packet log support for QCA6390, otherwise the data connection will stall within a minute or so. Enable it via debugfs and use trace-cmd to capture the pktlogs. echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter The mon status ring doesn't support interrupt so far, so host starts a timer to reap this ring. The timer handler also reaps the rxdma_err_dst_ring in case of monitor mode. As QCA6390 requires bss created ahead of starting vdev, so check vdev_start_delay for monitor mode. For QCA6390, it uses wbm_desc_rel_ring to return descriptors. It also uses rx_refill_buf_ring to fill mon buffer instead of rxdma_mon_buf_ring.

QCA6390 does not support monitor mode at the moment so disable it altogether, using a hack as mac80211 does not support disabling it otherwise. Add a boolean to hw_params to know if hardware supports monitor mode. IPQ8074 continues to support monitor mode normally.
