I'm try to compile 32 bit pae kernel from xen git repo. If i check sparse memory - i get error scripts/kconfig/conf -s arch/x86/Kconfig CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 CC kernel/bounds.s GEN include/linux/bounds.h CC arch/x86/kernel/asm-offsets.s In file included from include/linux/suspend.h:8, from arch/x86/kernel/asm-offsets_32.c:11, from arch/x86/kernel/asm-offsets.c:2: include/linux/mm.h:518:2: error: #error SECTIONS_WIDTH+NODES_WIDTH +ZONES_WIDTH > BITS_PER_LONG - NR_PAGEFLAGS make[1]: *** [arch/x86/kernel/asm-offsets.s] Error 1 make: *** [prepare0] Error 2 But if a check flat memory - compiling fine, but a can't get memory hotplug, does memory hotplug possible with flat memory ? Or only with sparse? Daniel, can You check this? -- Vasiliy G Tolstov Selfip.Ru
