Wander around the + different rates, singing wherever you can. And then, look at the + performance, and make a choice. Note that the wandering minstrel will + always wander in directions where he/she feels he/she will get paid + the best for his/her work. + +config MADWIFI_RCA_ONOE + bool "Use the Onoe rate control algorithm" + help + Onoe is a credit based RCA where the value of the credit is determined + by the frequency of successful, erroneous and retransmissions + accumulated during a fixed invocation period of 1000 ms. 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 + SampleRate decides on the transmission bit-rate based on the past + history of performance; it keeps a record of the number of successive + failures, the number of successful transmits and the total transmission + time along with the destination for that bit-rate. Stale samples are + removed based on a EWMA windowing mechanism. If in the sampling + process, no successful acknowledgment is received or the number of + packets sent is multiple of 10 on a specific link, it transmits the + packet with the highest rate which has not failed 4 successive times. + Other than that it transmits packets at the rate which has the lowest + average transmission time. + +endchoice diff --git a/package/madwifi/Makefile b/package/madwifi/Makefile index 697f2b68a..ef83702a8 100644 --- a/package/madwifi/Makefile +++ b/package/madwifi/Makefile @@ -25,48 +25,115 @@ PKG_BUILD_DIR:=$(KERNEL_BUILD_DIR)/$(if $(PKG_BRANCH),$(PKG_BRANCH),madwifi-trun include $(INCLUDE_DIR)/package.mk -# MADWIFI_DEBUG=1 +ifdef CONFIG_MADWIFI_BUS_DEFAULT + ifneq ($(CONFIG_TARGET_atheros),) + BUS:=AHB + else + ifneq ($(CONFIG_PCI_SUPPORT),) + BUS:=PCI + endif + endif -ifeq ($(ARCH),mips) - HAL_TARGET:=mips-be-elf -endif -ifeq ($(ARCH),mipsel) - HAL_TARGET:=mips-le-elf -endif -ifeq ($(ARCH),i386) - HAL_TARGET:=i386-elf -endif -ifeq ($(ARCH),i686) - HAL_TARGET:=i386-elf -endif -ifeq ($(BOARD),ixp4xx) - HAL_TARGET:=xscale-be-elf -endif -ifeq ($(BOARD),iop32x) - HAL_TARGET:=xscale-le-elf -endif -ifeq ($(ARCH),powerpc) - HAL_TARGET:=powerpc-be-elf -endif -ifeq ($(BOARD),storm) - HAL_TARGET:=armv4-le-elf + # XXX: remove this check later when we have PCI support properly detected on all targets + ifneq ($(CONFIG_TARGET_ar7)$(CONFIG_TARGET_uml),) + BUS:= + endif +else + ifdef CONFIG_MADWIFI_BUS_PCI + BUS:=PCI + else + ifdef CONFIG_MADWIFI_BUS_AHB + BUS:=AHB + endif + endif endif -ifneq ($(CONFIG_TARGET_atheros),) - BUS:=AHB - HAL_TARGET:=ap51 +ifdef CONFIG_MADWIFI_HAL_DEFAULT + ifeq ($(ARCH),mips) + HAL_TARGET:=mips-be-elf + endif + ifeq ($(ARCH),mipsel) + HAL_TARGET:=mips-le-elf + endif + ifeq ($(ARCH),i386) + HAL_TARGET:=i386-elf + endif + ifeq ($(ARCH),i686) + HAL_TARGET:=i386-elf + endif + ifeq ($(BOARD),ixp4xx) + HAL_TARGET:=xscale-be-elf + endif + ifeq ($(BOARD),iop32x) + HAL_TARGET:=xscale-le-elf + endif + ifeq ($(ARCH),powerpc) + HAL_TARGET:=powerpc-be-elf + endif + ifeq ($(BOARD),storm) + HAL_TARGET:=armv4-le-elf + endif + ifneq ($(CONFIG_TARGET_atheros),) + HAL_TARGET:=ap51 + endif else - ifneq ($(CONFIG_PCI_SUPPORT),) - BUS:=PCI + ifdef CONFIG_MADWIFI_HAL_MIPS_BE_ELF + HAL_TARGET:=mips-be-elf + endif + + ifdef CONFIG_MADWIFI_HAL_MIPS_LE_ELF + HAL_TARGET:=mips-le-elf endif + + ifdef CONFIG_MADWIFI_HAL_I386_ELF + HAL_TARGET:=i386-elf + endif + + ifdef CONFIG_MADWIFI_HAL_XSCALE_BE_ELF + HAL_TARGET:=xscale-be-elf + endif + + ifdef CONFIG_MADWIFI_HAL_XSCALE_LE_ELF + HAL_TARGET:=xscale-le-elf + endif + + ifdef CONFIG_MADWIFI_HAL_ARMV4_LE_ELF + HAL_TARGET:=armv4-le-elf + endif + + ifdef CONFIG_MADWIFI_HAL_AP30 + HAL_TARGET:=ap30 + endif + + ifdef CONFIG_MADWIFI_HAL_AP43 + HAL_TARGET:=ap43 + endif + + ifdef CONFIG_MADWIFI_HAL_AP51 + HAL_TARGET:=ap51 + endif + + ifdef CONFIG_MADWIFI_HAL_AP61 + HAL_TARGET:=ap61 + endif + +endif + +ifdef CONFIG_MADWIFI_RCA_MINSTREL + RATE_CONTROL:=minstrel +endif + +ifdef CONFIG_MADWIFI_RCA_ONOE + RATE_CONTROL:=onoe endif -# XXX: remove this check later when we have PCI support properly detected on all targets -ifneq ($(CONFIG_TARGET_ar7)$(CONFIG_TARGET_uml),) - BUS:= +ifdef CONFIG_MADWIFI_RCA_AMRR + RATE_CONTROL:=amrr endif -RATE_CONTROL:=minstrel +ifdef CONFIG_MADWIFI_RCA_SAMPLERATE + RATE_CONTROL:=sample +endif MADWIFI_FILES:= \ $(PKG_BUILD_DIR)/net80211/wlan.$(LINUX_KMOD_SUFFIX) \ @@ -102,7 +169,7 @@ ifeq ($(findstring PCI,$(BUS)),PCI) endif MADWIFI_APPLETS:=80211stats,athchans,athctrl,athkey,athstats,wlanconfig -ifneq ($(MADWIFI_DEBUG),) +ifdef CONFIG_MADWIFI_DEBUG MADWIFI_APPLETS:=$(strip $(MADWIFI_APPLETS)),athdebug,80211debug endif @@ -120,6 +187,13 @@ define KernelPackage/madwifi/description This package contains a driver for Atheros 802.11a/b/g chipsets. endef +define KernelPackage/madwifi/config + menu "MadWifi Configuration" + depends on PACKAGE_kmod-madwifi + source "$(SOURCE)/Config.in" + endmenu +endef + MAKE_ARGS:= \ PATH="$(TARGET_PATH)" \ ARCH="$(LINUX_KARCH)" \ @@ -131,7 +205,7 @@ MAKE_ARGS:= \ LDOPTS="--no-warn-mismatch " \ ATH_RATE="ath_rate/$(RATE_CONTROL)" \ WARNINGS="-Wno-unused" \ - $(if $(MADWIFI_DEBUG),,DEBUG="") \ + $(ifndef CONFIG_MADWIFI_DEBUG,DEBUG="") \ DOMULTI=1 MAKE_VARS:= \ |
