Spectral scan support is currently the only user of +RELAY in ath10k, and it unconditionally reserves a relay channel. + +Having debugfs support in ath10k is often useful even on very small +embedded routers, where we'd rather like to avoid the code size and RAM +usage of the relay support. While ath10k-based devices usually have more +resources than ath9k-based ones, it makes sense to keep the configuration +symmetric to ath9k, so the same base kernel without RELAY can be used for +both ath9k and ath10k hardware. + +Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net> +Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com> +--- + drivers/net/wireless/ath/ath10k/Kconfig | 9 ++++++++- + drivers/net/wireless/ath/ath10k/Makefile | 2 +- + drivers/net/wireless/ath/ath10k/spectral.h | 4 ++-- + 3 files changed, 11 insertions(+), 4 deletions(-) + +--- a/drivers/net/wireless/ath/ath10k/Kconfig ++++ b/drivers/net/wireless/ath/ath10k/Kconfig +@@ -51,12 +51,19 @@ config ATH10K_DEBUG + config ATH10K_DEBUGFS + bool "Atheros ath10k debugfs support" + depends on ATH10K && DEBUG_FS +- depends on RELAY + ---help--- + Enabled debugfs support + + If unsure, say Y to make it easier to debug problems. + ++config ATH10K_SPECTRAL ++ bool "Atheros ath10k spectral scan support" ++ depends on ATH10K_DEBUGFS ++ depends on RELAY ++ default n ++ ---help--- ++ Say Y to enable access to the FFT/spectral data via debugfs. ++ + config ATH10K_TRACING + depends on !KERNEL_3_4 + bool "Atheros ath10k tracing support" +--- a/drivers/net/wireless/ath/ath10k/Makefile ++++ b/drivers/net/wireless/ath/ath10k/Makefile +@@ -14,7 +14,7 @@ ath10k_core-y += mac.o \ + p2p.o \ + swap.o + +-ath10k_core-$(CPTCFG_ATH10K_DEBUGFS) += spectral.o ++ath10k_core-$(CPTCFG_ATH10K_SPECTRAL) += spectral.o + ath10k_core-$(CPTCFG_NL80211_TESTMODE) += testmode.o + ath10k_core-$(CPTCFG_ATH10K_TRACING) += trace.o + ath10k_core-$(CPTCFG_ATH10K_THERMAL) += thermal.o +--- a/drivers/net/wireless/ath/ath10k/spectral.h ++++ b/drivers/net/wireless/ath/ath10k/spectral.h +@@ -44,7 +44,7 @@ enum ath10k_spectral_mode { + SPECTRAL_MANUAL, + }; + +-#ifdef CPTCFG_ATH10K_DEBUGFS ++#ifdef CPTCFG_ATH10K_SPECTRAL + + int ath10k_spectral_process_fft(struct ath10k *ar, + struct wmi_phyerr_ev_arg *phyerr, +@@ -85,6 +85,6 @@ static inline void ath10k_spectral_destr + { + } + +-#endif /* CPTCFG_ATH10K_DEBUGFS */ ++#endif /* CPTCFG_ATH10K_SPECTRAL */ + + #endif /* SPECTRAL_H */ +--- a/local-symbols ++++ b/local-symbols +@@ -140,6 +140,7 @@ ATH10K_SDIO= + ATH10K_USB= + ATH10K_DEBUG= + ATH10K_DEBUGFS= ++ATH10K_SPECTRAL= + ATH10K_TRACING= + ATH10K_DFS_CERTIFIED= + WCN36XX= |
