If less than - 10% of the packets need to be retransmitted at a particular rate, Onoe - keeps increasing its credit point till the threshold value of 10 is - reached. At this point, the current transmission rate is increased to - the next available higher rate and the process repeated with credit - score of zero. Similar logic holds for deducting the credit score and - moving to a lower bit-rate for failed packet - transmission/retransmission attempts. However, once a bit-rate has - been marked as failure in the previous attempt, Onoe will not attempt - to select that bit-rate until 10 seconds have elapsed since the last - attempt. Due to the manner in which it operates, Onoe is conservative - in rate selection and is less sensitive to individual packet failure. - -config MADWIFI_RCA_AMRR - bool "Use the AMRR rate control algorithm" - help - AMRR uses Binary Exponential Backoff (BEB) technique to adapt the - length (threshold) of the sampling period used to change the values of - bit-rate and transmission count parameters. It uses probe packets and - depending on their transmission status adaptively changes the threshold - value. The adaptation mechanism ensures fewer failed - transmission/retransmission and higher throughput by not switching to a - higher rate as specified by the backoff mechanism. In addition to this, - the AMRR employs heuristics to capture the short-term variations of the - channel by judiciously setting the rate and transmission count - parameters. - config MADWIFI_RCA_SAMPLERATE bool "Use the SampleRate rate control algorithm" help diff --git a/package/madwifi/Makefile b/package/madwifi/Makefile index 250c6fd68d..632b77fec5 100644 --- a/package/madwifi/Makefile +++ b/package/madwifi/Makefile @@ -124,6 +124,9 @@ ifdef CONFIG_MADWIFI_RCA_SAMPLERATE RATE_CONTROL:=sample endif +ifneq ($(CONFIG_MADWIFI_SINGLE_MODULE),) +MADWIFI_FILES:= $(PKG_BUILD_DIR)/ath_hal/ath_hal.$(LINUX_KMOD_SUFFIX) +else MADWIFI_FILES:= \ $(PKG_BUILD_DIR)/net80211/wlan.$(LINUX_KMOD_SUFFIX) \ $(PKG_BUILD_DIR)/net80211/wlan_scan_ap.$(LINUX_KMOD_SUFFIX) \ @@ -134,9 +137,13 @@ MADWIFI_FILES:= \ $(PKG_BUILD_DIR)/net80211/wlan_ccmp.$(LINUX_KMOD_SUFFIX) \ $(PKG_BUILD_DIR)/net80211/wlan_tkip.$(LINUX_KMOD_SUFFIX) \ $(PKG_BUILD_DIR)/net80211/wlan_wep.$(LINUX_KMOD_SUFFIX) \ - $(PKG_BUILD_DIR)/net80211/wlan_xauth.$(LINUX_KMOD_SUFFIX) \ + $(PKG_BUILD_DIR)/net80211/wlan_xauth.$(LINUX_KMOD_SUFFIX) +endif -MADWIFI_AUTOLOAD:= \ +ifneq ($(CONFIG_MADWIFI_SINGLE_MODULE),) + MADWIFI_AUTOLOAD:= ath_hal +else + MADWIFI_AUTOLOAD:= \ wlan \ wlan_scan_ap \ wlan_scan_sta \ @@ -146,7 +153,8 @@ MADWIFI_AUTOLOAD:= \ wlan_ccmp \ wlan_tkip \ wlan_wep \ - wlan_xauth \ + wlan_xauth +endif ifeq ($(findstring AHB,$(BUS)),AHB) MADWIFI_FILES+= $(PKG_BUILD_DIR)/ath/ath_ahb.$(LINUX_KMOD_SUFFIX) @@ -202,14 +210,15 @@ MAKE_ARGS:= \ TOOLPATH="$(KERNEL_CROSS)" \ KERNELPATH="$(LINUX_DIR)" \ LDOPTS="--no-warn-mismatch " \ - ATH_RATE="ath_rate/$(RATE_CONTROL)" \ + ATH_RATE="$(RATE_CONTROL)" \ ATH_CAP_SUPERG_COMP="$(COMPRESSION)" \ DO_MULTI=1 \ + SINGLE_MODULE=$(if $(CONFIG_MADWIFI_SINGLE_MODULE),1) \ INCS="$(MADWIFI_INC)" \ $(if $(CONFIG_MADWIFI_DEBUG),,DEBUG=) WARNINGS="-Wno-unused" MAKE_VARS:= \ - COPTS="-DCONFIG_ATHEROS_RATE_DEFAULT='\"$(RATE_CONTROL)\"' -DATH_REVERSE_ENGINEERING=1" \ + COPTS="-DATH_REVERSE_ENGINEERING=1" \ ifeq ($(CONFIG_MADWIFI_UPSTREAM),) define Build/Prepare/HAL diff --git a/package/madwifi/patches/446-single_module.patch b/package/madwifi/patches/446-single_module.patch new file mode 100644 index 0000000000..2ad9af87e2 --- /dev/null +++ b/package/madwifi/patches/446-single_module.patch @@ -0,0 +1,778 @@ +--- a/ath/Makefile ++++ b/ath/Makefile +@@ -41,7 +41,6 @@ + # + + obj := $(firstword $(obj) $(SUBDIRS) .) +-TOP = $(obj)/.. + + ifeq ($(strip $(BUS)),AHB) + BUSNAME=ahb +@@ -57,7 +56,24 @@ COPTS += -DDFS_DOMAIN_ETSI -DDFS_DOMAIN_ + include $(TOP)/Makefile.inc + + obj-m += ath_$(BUSNAME).o +-ath_$(BUSNAME)-objs := if_ath.o if_ath_radar.o if_ath_$(BUSNAME).o ++ath_objs := if_ath.o if_ath_radar.o if_ath_$(BUSNAME).o ++ath_$(BUSNAME)-objs := $(ath_objs) ++ ++ifneq ($(SINGLE_MODULE),) ++include $(TOP)/net80211/Makefile ++include $(TOP)/ath_rate/sample/Makefile ++include $(TOP)/ath_rate/minstrel/Makefile ++RC_DECLARE=$(foreach R,$(ATH_RATE),extern void ath_rate_$(R)_init(void);extern void ath_rate_$(R)_exit(void);) ++RC_INIT=$(foreach R,$(ATH_RATE),ath_rate_$(R)_init();) ++RC_EXIT=$(foreach R,$(ATH_RATE),ath_rate_$(R)_exit();) ++ ++ath_$(BUSNAME)-objs += $(patsubst %,../net80211/%,$(wlan-objs) $(foreach var,wep tkip ccmp acl xauth scan_sta scan_ap,$(wlan_$(var)-objs))) $(foreach RC,$(ATH_RATE),$(patsubst %,../ath_rate/$(RC)/%,$(ath_rate_$(RC)-objs))) ++ifdef LINUX24 ++ ath_$(BUSNAME)-linkobjs := $(ath_objs) $(wlan-objs) $(foreach var,wep tkip ccmp acl xauth scan_sta scan_ap,$(wlan_$(var)-objs)) $(foreach RC,$(ATH_RATE),$(ath_rate_$(RC)-objs)) ++endif ++ ++EXTRA_CFLAGS += -DSINGLE_MODULE -DRC_INIT="$(RC_INIT)" -DRC_EXIT="$(RC_EXIT)" -DRC_DECLARE="$(RC_DECLARE)" ++endif + + INCS += -I$(TOP) -I$(ATH_HAL) -I$(HAL) -I$(WLAN) + +@@ -72,13 +88,8 @@ install: + test -d $(DESTDIR)/$(KMODPATH) || mkdir -p $(DESTDIR)/$(KMODPATH) + install -m 0644 ath_$(BUSNAME).$(KMODSUF) $(DESTDIR)/$(KMODPATH) + +-clean: +- rm -f *~ *.o *.ko *.mod.c .*.cmd +- rm -f .depend .version .*.o.flags .*.o.d +- rm -rf .tmp_versions +- + ath_$(BUSNAME).o: $(ath_$(BUSNAME)-objs) +- $(LD) $(LDOPTS) -o ath_$(BUSNAME).$(KMODSUF) -r $(ath_$(BUSNAME)-objs) ++ $(LD) $(LDOPTS) -o ath_$(BUSNAME).$(KMODSUF) -r $(if $(ath_$(BUSNAME)-linkobjs),$(ath_$(BUSNAME)-linkobjs),$(ath_$(BUSNAME)-objs)) + + if_ath_hal.h: $(HAL)/ah.h + $(TOP)/scripts/if_ath_hal_generator.pl $< $@ +--- a/net80211/ieee80211_acl.c ++++ b/net80211/ieee80211_acl.c +@@ -281,16 +281,6 @@ acl_getpolicy(struct ieee80211vap *vap) + return as->as_policy;
