The generic kernel does not include all options, subsystems 7# and device drivers, but should be useful for most applications. 8# 9# The machine description file can be customised for your specific 10# machine to reduce the kernel size and improve its performance. 11# 12# For further information on compiling NetBSD kernels, see the config(8) 13# man page. 14# 15# For further information on hardware support for this architecture, see 16# the intro(4) man page. For further information about kernel options 17# for this architecture, see the options(4) man page. For an explanation 18# of each device driver in this file see the section 4 man page for the 19# device. 20 21include "arch/arc/conf/std.arc" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#ident "GENERIC-$Revision: 1.93 $" 26 27maxusers 32 # estimated number of users 28 29# Platform support 30options PLATFORM_ACER_PICA_61 # PICA, NEC ImageRISCstation 31options PLATFORM_DESKTECH_ARCSTATION_I # DeskStation rPC44 32options PLATFORM_DESKTECH_TYNE # DeskStation Tyne 33options PLATFORM_MICROSOFT_JAZZ # MIPS Magnum 34options PLATFORM_NEC_J96A # NEC Express 5800/240 EISA R4K 35options PLATFORM_NEC_JC94 # NEC Express 5800/230 PCI R4K 36options PLATFORM_NEC_R94 # NEC RISCstation 2200 EISA 37options PLATFORM_NEC_R96 # NEC Express RISCserver, RISCserver 2200 38options PLATFORM_NEC_RAX94 # NEC RISCstation 2200 PCI 39options PLATFORM_NEC_RD94 # NEC RISCstation 2250 40options PLATFORM_SNI_RM200PCI 41 42# Standard system options 43 44options RTC_OFFSET=0 # hardware clock is this many mins. west of GMT 45options NTP # NTP phase/frequency locked loop 46 47options KTRACE # system call tracing via ktrace(1) 48options SYSTRACE # system call vetting via systrace(1) 49 50options SYSVMSG # System V-like message queues 51options SYSVSEM # System V-like semaphores 52#options SEMMNI=10 # number of semaphore identifiers 53#options SEMMNS=60 # number of semaphores in system 54#options SEMUME=10 # max number of undo entries per process 55#options SEMMNU=30 # number of undo structures in system 56options SYSVSHM # System V-like memory sharing 57#options SHMMAXPGS=1024 # 1024 pages is the default 58 59options LKM # loadable kernel modules 60 61options USERCONF # userconf(4) support 62#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 63 64# Enable experimental buffer queue strategy for better responsiveness under 65# high disk I/O load.
