Hari Chandrakanthan 60afa4f4e1 ath11k: disable spectral scan during spectral deinit [ Upstream commit `161c64de23` ] When ath11k modules are removed using rmmod with spectral scan enabled, crash is observed. Different crash trace is observed for each crash. Send spectral scan disable WMI command to firmware before cleaning the spectral dbring in the spectral_deinit API to avoid this crash. call trace from one of the crash observed: [ 1252.880802] Unable to handle kernel NULL pointer dereference at virtual address 00000008 [ 1252.882722] pgd = 0f42e886 [ 1252.890955] [00000008] *pgd=00000000 [ 1252.893478] Internal error: Oops: 5 [#1] PREEMPT SMP ARM [ 1253.093035] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.4.89 #0 [ 1253.115261] Hardware name: Generic DT based system [ 1253.121149] PC is at ath11k_spectral_process_data+0x434/0x574 [ath11k] [ 1253.125940] LR is at 0x88e31017 [ 1253.132448] pc : [<7f9387b8>] lr : [<88e31017>] psr: a0000193 [ 1253.135488] sp : 80d01bc8 ip : 00000001 fp : 970e0000 [ 1253.141737] r10: 88e31000 r9 : 970ec000 r8 : 00000080 [ 1253.146946] r7 : 94734040 r6 : a0000113 r5 : 00000057 r4 : 00000000 [ 1253.152159] r3 : e18cb694 r2 : 00000217 r1 : 1df1f000 r0 : 00000001 [ 1253.158755] Flags: NzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user [ 1253.165266] Control: 10c0383d Table: 5e71006a DAC: 00000055 [ 1253.172472] Process swapper/0 (pid: 0, stack limit = 0x60870141) [ 1253.458055] [<7f9387b8>] (ath11k_spectral_process_data [ath11k]) from [<7f917fdc>] (ath11k_dbring_buffer_release_event+0x214/0x2e4 [ath11k]) [ 1253.466139] [<7f917fdc>] (ath11k_dbring_buffer_release_event [ath11k]) from [<7f8ea3c4>] (ath11k_wmi_tlv_op_rx+0x1840/0x29cc [ath11k]) [ 1253.478807] [<7f8ea3c4>] (ath11k_wmi_tlv_op_rx [ath11k]) from [<7f8fe868>] (ath11k_htc_rx_completion_handler+0x180/0x4e0 [ath11k]) [ 1253.490699] [<7f8fe868>] (ath11k_htc_rx_completion_handler [ath11k]) from [<7f91308c>] (ath11k_ce_per_engine_service+0x2c4/0x3b4 [ath11k]) [ 1253.502386] [<7f91308c>] (ath11k_ce_per_engine_service [ath11k]) from [<7f9a4198>] (ath11k_pci_ce_tasklet+0x28/0x80 [ath11k_pci]) [ 1253.514811] [<7f9a4198>] (ath11k_pci_ce_tasklet [ath11k_pci]) from [<8032227c>] (tasklet_action_common.constprop.2+0x64/0xe8) [ 1253.526476] [<8032227c>] (tasklet_action_common.constprop.2) from [<803021e8>] (__do_softirq+0x130/0x2d0) [ 1253.537756] [<803021e8>] (__do_softirq) from [<80322610>] (irq_exit+0xcc/0xe8) [ 1253.547304] [<80322610>] (irq_exit) from [<8036a4a4>] (__handle_domain_irq+0x60/0xb4) [ 1253.554428] [<8036a4a4>] (__handle_domain_irq) from [<805eb348>] (gic_handle_irq+0x4c/0x90) [ 1253.562321] [<805eb348>] (gic_handle_irq) from [<80301a78>] (__irq_svc+0x58/0x8c) Tested-on: QCN6122 hw1.0 AHB WLAN.HK.2.6.0.1-00851-QCAHKSWPL_SILICONZ-1 Signed-off-by: Hari Chandrakanthan <quic_haric@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/1649396345-349-1-git-send-email-quic_haric@quicinc.com Signed-off-by: Sasha Levin <sashal@kernel.org>		2022-06-09 10:20:52 +02:00

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
