I tried nfs command on KZM-A9-GT board and it fails every time with "ERROR: Cannot umount".
Current NFS_TIMEOUT value is 2000UL. It seems too short. I changed this to 10000UL then it succeeds.

KZM-A9-GT board?  This is an out of tree port, isn't it?

Are you sure the problems are not in the board specific code?

> Current NFS_TIMEOUT value is 2000UL. It seems too short. I changed this to 10000UL then it succeeds.

Please don't modify global code when you just need different settings
for a single piece of hardware.  Especially here, were there are
chances that the problems are actually in the board support code, and
not in the global network code.

Best regards,

Wolfgang Denk

OK. I will try the same thing on an in-tree board (maybe, panda board) to check if this is board specific or not.

I did on a panda board. It has the same problem and this patch solves it. So this is not board specific problem. Please consider to change global setting of NFS_TIMEOUT in nfs.c.
I hope someone else tries nfs command on the other board.



Following is the detail I did:

The default config of pand board disables NFS command.
So add this line in omap4_panda.h
#define COFNIG_CMD_NFS
(This line must be after #include configs/omap4_common.h>

I had trouble to use network on a panda board at the source from u-boot master git.
Instead, I used source code from Linaro git.
(I think this is another issue. Just focus NFS timeout now.)

Before applying the patch: error occurs like this.

net/nfs.c is not the right place to make board specific adjustments.

I am still not convinced this is an issue with the global code.  It
could be your NFS server as well.

If there are really boards which need longer timeouts, these should be
set in the board config files.

Best regards,

Wolfgang Denk

I'm not convinced either.  It clearly depends on the speed of your
server, the speed of the connection, the size of the file you are
transferring, etc.

In fact I would rather the constant were not defined there at all... but it is.

At a minimum it should look like this:


 #define HASHES_PER_LINE 65     /* Number of "loading" hashes per line  */
 #define NFS_RETRY_COUNT 30
+#ifdef CONFIG_NFS_TIMEOUT
+#define NFS_TIMEOUT CONFIG_NFS_TIMEOUT
+#else
 #define NFS_TIMEOUT 2000UL
+#endif

 static int fs_mounted;
 static unsigned long rpc_id;


...with CONFIG_NFS_TIMEOUT defined for your board.

Is the timeout for completing the transfer, or for making forward progress?

The timeout is reset each time that NetSetTimeout() is called.  For
NFS, that happens when a transfer starts, when the timeout occurs (a
retry begins), and when a "read request" response comes from the
server.  I would bet that means it should be a timeout for making
progress, but I'm not an NFS protocol expert.

Yes, NFS_TIMEOUT should be configurable.

NFS_TIMEOUT is constant value defined in net/nfs.c. But sometimes it needs to adjust.
This patch enables to override NFS_TIMEOUT by defining CONFIG_NFS_TIMEOUT in a board specific config file.

NFS_TIMEOUT is constant value defined in net/nfs.c. But sometimes it needs to adjust.
This patch enables to override NFS_TIMEOUT by defining CONFIG_NFS_TIMEOUT in a board specific config file.
For example,
#define CONFIG_NFS_TIMEOUT 10000UL

Please add documentation to the new CONFIG_ option to the README.

Someone marked it as RFC in patchwork, so I lost track of it.

I'll apply it to next.

Thanks,

No problem... the RFC should have been removed from the subject line
if Tetsuyuki Kobayashi expected it to be applied.
