Hello ,
I’m new to netmap where I’m trying to insert netmap.ko module after compiling
my kernel and I’m shown with the following error:
netmap: Unknown symbol split_page (err 0)
Here are the steps and different methods I followed:
I. Compile Kernel 3.2.0
1. My Ubuntu 12.04 machine has a kernel version 3.2.0-90-generic, so i got the
linux source by:
sudo apt-get source linux-source-3.2.0
2. Then i work on trying to compile the kernel
a. sudo make menuconfig — Keep default config
b. sudo sed -i s/CONFIG_RTS5139=m/CONFIG_RTS5139=n/ .config - to avoid
compilation errors
c. sudo make clean
d. sudo make -j10
e. sudo make bzImage
f. sudo make modules
g.sudo make modules_install
h. sudo make install
i. sudo update-grub2
j. sudo reboot.
2 b. On checking kernel version using name -r , this is the kernel version -
3.2.79
3. Then i download the netmap-master branch from git and upload it to my
machine , cannot use git clone as it doesn’t support external connections.
4.Unzipping the bundle and switch to LINUX folder to run ./configure
5. Here i received errors where netmap-master/LINUX/drivers/ext-patch couldn’t
be downloaded due to failure to connect.
6. I downloaded these drivers and placed them in that path.
7. I received a warning telling cannot find complete kernel sources, which i
referenced later as
./configure —kernel-sources = /lib/modules/linux-source-(uname -r)/build
8. Then after clearing all warning and errors, the generated netmap.ko file I
try to insert , which gives me the error
netmap: Unknown symbol split_page (err 0)
II. Avoid kernel compliation
1. Then i download the netmap-master branch from git and upload it to my
machine , cannot use git clone as it doesn’t support external connections.
2.Unzipping the bundle and switch to LINUX folder to run ./configure
3. Here i received errors where netmap-master/LINUX/drivers/ext-patch couldn’t
be downloaded due to failure to connect.
4. I downloaded these drivers and placed them in that path.
5. I received a warning telling cannot find complete kernel sources, which i
referenced later as
./configure —kernel-sources = /lib/modules/linux-source-(uname -r)/build
6. Then after clearing all warning and errors, the generated netmap.ko file I
try to insert , which gives me the error
netmap: Unknown symbol split_page (err 0)
III. Tried switching to FreeBSD
Cannot download the FreeBSD 10.2 image due to security reasons
mentioned in git / wget.
I’m totally stuck for the past 2 weeks and would appreciate help on this.
Thanks
H
