From f9022964cfa0a44984d2efa2dafe3452899acfdf Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 25 Jan 2017 15:32:18 +0100 Subject: [PATCH] ath9k: add stability fixes for long standing hang issues (FS#13, #34, #373, #383) The radio would stop communicating completely. This issue was easiest to trigger on AR913x devices, e.g. the TP-Link TL-WR1043ND, but other hardware was occasionally affected as well. The most critical issue was a race condition in disabling/enabling IRQs between the IRQ handler and the IRQ processing tasklet Signed-off-by: Felix Fietkau --- ...me-tx_complete_work-to-hw_check_work.patch | 175 ++++++++++++++++++ ...-check-if-the-chip-failed-to-wake-up.patch | 30 +++ ...6-ath9k-check-for-deaf-rx-path-state.patch | 100 ++++++++++ ...condition-in-enabling-disabling-IRQs.patch | 165 +++++++++++++++++ .../410-ath9k_allow_adhoc_and_ap.patch | 2 +- .../patches/500-ath9k_eeprom_debugfs.patch | 4 +- .../mac80211/patches/501-ath9k_ahb_init.patch | 2 +- .../patches/512-ath9k_channelbw_debugfs.patch | 4 +- .../patches/530-ath9k_extra_leds.patch | 20 +- .../patches/542-ath9k_debugfs_diag.patch | 10 +- .../patches/543-ath9k_entropy_from_adc.patch | 6 +- ...544-ath9k-ar933x-usb-hang-workaround.patch | 4 +- .../patches/548-ath9k_enable_gpio_chip.patch | 2 +- .../549-ath9k_enable_gpio_buttons.patch | 2 +- ...-EEPROM-fields-in-Little-Endian-form.patch | 50 +++-- .../patches/560-ath9k_ubnt_uap_plus_hsr.patch | 4 +- 16 files changed, 523 insertions(+), 57 deletions(-) create mode 100644 package/kernel/mac80211/patches/354-ath9k-rename-tx_complete_work-to-hw_check_work.patch create mode 100644 package/kernel/mac80211/patches/355-ath9k_hw-check-if-the-chip-failed-to-wake-up.patch create mode 100644 package/kernel/mac80211/patches/356-ath9k-check-for-deaf-rx-path-state.patch create mode 100644 package/kernel/mac80211/patches/357-ath9k-fix-race-condition-in-enabling-disabling-IRQs.patch diff --git a/package/kernel/mac80211/patches/354-ath9k-rename-tx_complete_work-to-hw_check_work.patch b/package/kernel/mac80211/patches/354-ath9k-rename-tx_complete_work-to-hw_check_work.patch new file mode 100644 index 0000000000..31a0277e1c --- /dev/null +++ b/package/kernel/mac80211/patches/354-ath9k-rename-tx_complete_work-to-hw_check_work.patch @@ -0,0 +1,175 @@ +From: Felix Fietkau +Date: Wed, 25 Jan 2017 12:57:05 +0100 +Subject: [PATCH] ath9k: rename tx_complete_work to hw_check_work + +Also include common MAC alive check.
