Hello,
I'm trying to build a 2.6.22.1-rt9 kernel for a P3.
I used 'make xconfig' to create .config http://linux.kernel.free.fr/latency/config-2.6.22.1-rt9-adlink
I get the following warning:
LD vmlinux SYSMAP System.map SYSMAP .tmp_System.map MODPOST vmlinux WARNING: kernel/built-in.o(.text+0x19152): Section mismatch: reference to .init.text: (between 'kthreadd' and 'init_waitqueue_head') AS arch/i386/boot/bootsect.o LD arch/i386/boot/bootsect AS arch/i386/boot/setup.o LD arch/i386/boot/setup AS arch/i386/boot/compressed/head.o CC arch/i386/boot/compressed/misc.o OBJCOPY arch/i386/boot/compressed/vmlinux.bin GZIP arch/i386/boot/compressed/vmlinux.bin.gz LD arch/i386/boot/compressed/piggy.o LD arch/i386/boot/compressed/vmlinux OBJCOPY arch/i386/boot/vmlinux.bin HOSTCC arch/i386/boot/tools/build BUILD arch/i386/boot/bzImage Root device is (3, 1) Boot sector 512 bytes. Setup is 7082 bytes. System is 1142 kB Kernel: arch/i386/boot/bzImage is ready (#1) Building modules, stage 2. MODPOST 0 modules
I also get the following warnings (which seem less severe)
CC drivers/pci/pci.o CC drivers/pci/quirks.o CC drivers/pci/pci-driver.o CC drivers/pci/search.o drivers/pci/search.c: In function `pci_find_slot': drivers/pci/search.c:99: warning: `pci_find_device' is deprecated (declared at include/linux/pci.h:477) drivers/pci/search.c: At top level: drivers/pci/search.c:434: warning: `pci_find_device' is deprecated (declared at drivers/pci/search.c:241) drivers/pci/search.c:434: warning: `pci_find_device' is deprecated (declared at drivers/pci/search.c:241) CC drivers/pci/pci-sysfs.o CC drivers/pci/rom.o
Finally, I note that X86_CMPXCHG64 is no longer defined since its specification was changed between 2.6.20 and 2.6.22.
config X86_CMPXCHG64 bool - depends on !M386 && !M486 + depends on X86_PAE default y
Will this have an impact on spinlocks? RCU? something else?
