Subject: [PATCH AUTOSEL 5.4 068/108] ath10k: start recovery process when read int status fail for sdio
Date: Sat, 11 Apr 2020 19:09:03 -0400 [thread overview]
Message-ID: <20200411230943.24951-68-sashal@kernel.org> (raw)
In-Reply-To: <20200411230943.24951-1-sashal@kernel.org>
From: Wen Gong <wgong@codeaurora.org>
[ Upstream commit 37b7ecb75627699e96750db1e0c5ac56224245df ]
When running simulate crash stress test, it happened
"failed to read from address 0x800: -110".
Test steps:
1. Run command continuous
echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash
2. error happened and it did not begin recovery for long time.
[74377.334846] ath10k_sdio mmc1:0001:1: simulating soft firmware crash
[74378.378217] ath10k_sdio mmc1:0001:1: failed to read from address 0x800: -110
[74378.378371] ath10k_sdio mmc1:0001:1: failed to process pending SDIO interrupts: -110
It has sdio errors since it can not read MBOX_HOST_INT_STATUS_ADDRESS,
then it has to do recovery process to recovery ath10k.
Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.
