Subject: [parisc-linux] 64bit kernel & nfs module: Global Offset Table overflow (used 1068, allowed 1023)
Date: Wed, 18 Oct 2006 22:03:11 +0200	[thread overview]
Message-ID: <200610182203.11413.deller@gmx.de> (raw)

With a 64bit Kernel (git head):

c3000:/home/cvs# modprobe nfs
FATAL: Error inserting nfs (/lib/modules/2.6.19-rc2-pa0/kernel/fs/nfs/nfs.ko): Invalid argument

dmesg says:
nfs: Global Offset Table overflow (used 1068, allowed 1023)


In the source code arch/parisc/kernel/module.c I found:

/* Maximum number of GOT entries. We use a long displacement ldd from
 * the bottom of the table, which has a maximum signed displacement of
 * 0x3fff; however, since we're only going forward, this becomes
 * 0x1fff, and thus, since each GOT entry is 8 bytes long we can have
 * at most 1023 entries */
#define MAX_GOTS        1023

Since I don't have any real idea about GOT and modules in general:
Isn't it possible to increase this number for 64bit kernels ?

Helge
