/root/netmap/LINUX/e1000e/netdev.o Error 1 #2 #14

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

I'm trying to install Netmap in a server with a Intel(R) Xeon(R) CPU E3-1270 V2 
@ 3.50GHz and 16GB of memory and Debian 7.6. My server has a Intel PRO/1000 PT 
Dual Port (EXPI9402PTBLK - 82571GB), and I'm using these driver and patches:

I'm have kernel-headers and kernel-source and downloaded Netmap from git clone 
https://code.google.com/p/netmap/

I configured "/netmap/LINUX/Makefile" to enable e1000e driver like described in 
README file.

CONFIG_IXGBE=m CONFIG_IGB=m \
CONFIG_BNX2X=m CONFIG_MLX4=m \

But, when I try to install, I receive this error:

There are two separate issues here:
- CONFIG_E1000E should be left at the original value, namely 'm'. There must be 
some unclear instructions in the README, can you please point out the passage 
that lead you to make that change? Also, please revert to the initial makefile, 
then run 'make clean' and then retry.
- our e1000e and igb patches are failing on your kernel. Can you please attach 
a tar.gz of the e1000e and igb directories as left by the failed make?

answer: I followed this guide: 
https://cnp.neclab.eu/getting-started/#modular-vale (Attach and detach NICs 
to/from the switch)

- our e1000e and igb patches are failing on your kernel. Can you please attach 
a tar.gz of the e1000e and igb directories as left by the failed make?

answer: I'm trying to attach tar.gz file but I receive a bad request page. Is 
there any other way to send you this tar.gz (like mail)?

Thank you.

Hi, I sent to you the files that you ask me.

GoogleCodeExporter commented 9 years ago 
thanks. Your e1000e, igb and virtio_net drivers contain some additional patches 
wrt the stock ones in linux 3.2.0 vanilla, and therefore out standard patches 
don't work. If you don't need igb and virtio_net, you can remove the relevant 
patches, do that the Makefile will not try to compile them:

rm patches/diff--igb--*
rm patches/diff--virtio_net.c--*

For e1000e I have applied the required bits manually and produced the attached 
diff--e1000e--30100--30400. Just put the the file in the patches directory and 
then run:

make clean
make

I did some tests, but I got the same error.

First, I did what you asked me (remove igb and virtio diff patches and included 
diff--e1000e--30100--30400). Another test that I did was remove all diff files 
and put only diff--e1000e--30100--30400. I removed all modules from makefile 
but in all these cenarios I got the same error.

Downgrade my kernel is unfeasible.

Do you have any other idea?

my fault. The patch I gave you contained some error, plus you also need an 
updated if_e1000e_netmap.h. Please replace the corresponding files in LINUX 
with the attached files, then 'make clean' and 'make' as before. If you only 
need e1000e, is perfectly fine to delete all other patches.

I'll work in this error too, and I'll report some evolution.

It's the same problem again, your e1000e driver is newer than the rest of your 
kernel. Unfortunately, I cannot test compilation by myself in this case. This 
latter error should be caused by if_e1000e_netmap.h, where we have:

...
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 4, 0)
#define NM_WR_TX_TAIL(_x)       writel(_x, txr->tail)   // XXX tx_ring
#define NM_WR_RX_TAIL(_x)       writel(_x, rxr->tail)   // XXX rx_ring
#define NM_RD_TX_HEAD()         readl(txr->head)
#else
#define NM_WR_TX_TAIL(_x)       writel(_x, adapter->hw.hw_addr + txr->tail)
#define NM_WR_RX_TAIL(_x)       writel(_x, adapter->hw.hw_addr + rxr->tail)
#define NM_RD_TX_HEAD()         readl(adapter->hw.hw_addr + txr->head)
#endif /* < 3.4.0 */
...

This does not work for you, since you have a 3.2 kernel, but your e1000e driver 
contains code from much later kernels. Can you please try to replace the "4" in 
"KERNEL_VERSION_CODE(3, 4, 0)"  with a "2" and see if that helps?
