| |
i compiled 2.2.13 with the dmasound sound driver. when i try to insmod the module i get: unresolved symbol machine_is_compatible
this function is in the System.map: c0118534 T machine_is_compatible ,but it is not in /proc/ksyms so it is not an exported symbol right?
it is defined in linux/arch/ppc/kernel/prom.c it basically finds the root device and calls device_is_compatible
device_is_compatible is defined in System.map: c00d9780 ? __kstrtab_device_is_compatible c00ddbe0 ? __ksymtab_device_is_compatible c01180f0 T device_is_compatible
so i looked and i see that device_is_compatible is made exported in linux/arch/ppc/kernel/ppc_ksyms.c: EXPORT_SYMBOL(device_is_compatible);
ppc_ksyms.c includes prom.c
is dmasound failing because the function machine_is_compatible is not exported?
can i fix this by adding EXPORT_SYMBOL(machine_is_compatible); to ppc_ksyms.c ?
what part in any of this do the files in linux/include/linux/modules play? there is a ppc_ksyms.ver and ppc_ksyms.stamp ppc_ksyms.ver has a couple of statements that have to do with device_is_compatible
for your reference: sound worked when sound was compiled into the kernel(2.2.6 though). the correct System.map was loaded, verified with dmesg and /var/log/messages.
unrelated but... soundcore.o was already loaded alias sound dmasound added to /etc/conf.modules
can you reply directly to me too, i get the kernel-digest. thanks, -brandon
