Default Memory limit

Hi all,

I have installed NetBSD 5.1 amd64 on my laptop and it reboot every time.

I had the same problem under FreeBSD and the solution was to set a knob hw.physmem=3G in the file /loader.conf.

But, i have not find this entry under NetBSD.

How can i limit the memory on my laptop ?

Thanks a lot

In the source of the kernel, we have the possibility to limit the max size of physical memory.

options         PHYSMEM_MAX_SIZE=3072   # max size of physical memory (in MB)
But, when i want to recompile the new kernel, i have this error :

#   compile  MYKERNEL/machdep.o
cc -mcmodel=kernel -mno-red-zone -ffreestanding -fno-zero-initialized-in-bss -O2 -fno-omit-frame-pointer -std=gnu99 -fno-strict-aliasing -Werror -Wall -Wno-main -Wno-format-zero-length -Wpointer-arith -Wmissing-prototypes -Wstrict-prototypes -Wswitch -Wshadow -Wcast-qual -Wwrite-strings -Wno-unreachable-code -Wno-sign-compare -Wno-pointer-sign -Wno-attributes -Wextra -Wno-unused-parameter -Werror -Damd64 -Dx86_64 -I. -I../../../../../common/include -I../../../../arch -I../../../.. -nostdinc -DLKM -DMAXUSERS=64 -D_KERNEL -D_KERNEL_OPT -I../../../../lib/libkern/../../../common/lib/libc/quad -I../../../../lib/libkern/../../../common/lib/libc/string -I../../../../lib/libkern/../../../common/lib/libc/arch/x86_64/string -I../../../../external/isc/atheros_hal/dist -I../../../../external/isc/atheros_hal/ic -I../../../../../common/include -I../../../../dist/ipf -c ../../../../arch/amd64/amd64/machdep.c

../../../../arch/amd64/amd64/machdep.c: In function 'add_mem_cluster':
../../../../arch/amd64/amd64/machdep.c:1248: warning: implicit declaration of function 'MBTOB'
How can i do to remove this warning ?

Warnings issued by the compiler are not errors. For example I also get warnings when I compile Bernstein's daemontools and djbdns on OpenBSD, but the compiler just continues and the programs run fine..

In your case the problem is cc1: warnings being treated as errors. For something this specify to the NetBSD kernel, you probably get more response at one of the NetBSD mailing lists.

You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
