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.

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.

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.

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.
