See /boot/device.hints and/or the 'hints' config(8) directive. 11# 12# Please use ``make LINT'' to create an old-style LINT file if you want to 13# do kernel test-builds. 14# 15# This file contains machine independent kernel configuration notes. For 16# machine dependent notes, look in /sys/<arch>/conf/NOTES. 17# 18 19# 20# NOTES conventions and style guide: 21# 22# Large block comments should begin and end with a line containing only a 23# comment character. 24# 25# To describe a particular object, a block comment (if it exists) should 26# come first. Next should come device, options, and hints lines in that 27# order. All device and option lines must be described by a comment that 28# doesn't just expand the device or option name. Use only a concise 29# comment on the same line if possible. Very detailed descriptions of 30# devices and subsystems belong in man pages. 31# 32# A space followed by a tab separates 'options' from an option name. Two 33# spaces followed by a tab separate 'device' from a device name. Comments 34# after an option or device should use one space after the comment character. 35# To comment out a negative option that disables code and thus should not be 36# enabled for LINT builds, precede 'options' with "#!". 37# 38 39# 40# This is the ``identification'' of the kernel. Usually this should 41# be the same as the name of your kernel. 42# 43ident LINT 44 45# 46# The `maxusers' parameter controls the static sizing of a number of 47# internal system tables by a formula defined in subr_param.c. 48# Omitting this parameter or setting it to 0 will cause the system to 49# auto-size based on physical memory. 50# 51maxusers 10 52 53# To statically compile in device wiring instead of /boot/device.hints 54#hints "LINT.hints" # Default places to look for devices. 55 56# Use the following to compile in values accessible to the kernel 57# through getenv() (or kenv(1) in userland).

It's all controlled by a 646# bit mask (settable by socket opt and 647# by sysctl). Including will not cause 648# logging until you set the bits.. but it 649# can be quite verbose.. so without this 650# option we don't do any of the tests for 651# bits and prints.. which makes the code run 652# faster.. if you are not debugging don't use. 653options SCTP_DEBUG 654# 655# This option turns off the CRC32c checksum.

Details of the exact nature of the bug are sketchy, but some can be 2128# found at https://forum.openwrt.org/viewtopic.php?pid=70060 on pages 4, 5 and 2129# 6. This option enables this workaround. There is a performance penalty 2130# for this work around, but without it things don't work at all. The DMA 2131# from the card usually bursts 128 bytes, but on the affected CPUs, only 2132# 4 are safe. 2133options AH_RXCFG_SDMAMW_4BYTES 2134#device ath_ar9160 # AR9160 chips 2135#device ath_ar9280 # AR9280 chips 2136#device ath_ar9285 # AR9285 chips 2137device ath_rate_sample # SampleRate tx rate control for ath 2138device bwi # Broadcom BCM430* BCM431* 2139device bwn # Broadcom BCM43xx 2140device malo # Marvell Libertas wireless NICs. 2141device mwl # Marvell 88W8363 802.11n wireless NICs. 2142device mwlfw 2143device ral # Ralink Technology RT2500 wireless NICs. 2144 2145# Use sf_buf(9) interface for jumbo buffers on ti(4) controllers. 2146#options TI_SF_BUF_JUMBO 2147# Turn on the header splitting option for the ti(4) driver firmware.
