Re: I have a problem with iSCSI on AMD64 Xen HVM
int max = 24 /* MAX_SKB_FRAGS + (rx-status = RX_COPY_THRESHOLD) */; I've just recompiled XENHVM setting this for a quick test: int max = MAX_SKB_FRAGS; Before, I was receiving said error message a lot; now it's gone. Also, throughput has massively increased! My test setup was: 2x FreeBSD/amd64 8.2-RC2 (compiled about a week ago), XENHVM kernel. Both DomU's were running on the same physical machine (CentOS 5.5 x86_64 with Xen 4.3.3 on Intel i7), their xn0 NICs are using the same bridge on Dom0. I was able to trigger the error message on the receiving side by doing a simple scp test.bin target:/dev/null from one DomU to the other. Throughput dropped within seconds from ~40MB/sec below 2MB/sec. Now, with that change in place, throughput remains well above 50MB/sec! (approximates actual disk read speed minus SSH compression/encryption overhead) Which would be the right value for max? This was obviously only a quick, dirty test. I haven't got a clue either, where the max=5 came from, but it doesn't seem to be a reasonable value.

xennet_get_responses: too many frags 11 max 5
[..]
The following in sys/dev/xen/netfront/netfront.c xennet_get_responses()
looks a little bit suspicious:
int max = 5 /* MAX_TX_REQ_FRAGS + (rx-status = RX_COPY_THRESHOLD) */;
...together with the check at the end of the function (the only place
where max is used) which produces the error message you see:
if (unlikely(frags max)) {
if (net_ratelimit())
WPRINTK(Too many frags\n);
printf(%s: too many frags %d max %d\n, __func__, frags,
max);
err = E2BIG;
}
MAX_TX_REQ_FRAGS is defined as follows in the same file:
#define MAX_TX_REQ_FRAGS (65536 / PAGE_SIZE + 2)
...which produces already 18. Where does this max = 5 come from?
Either max is wrong or I do not understand the comment on the
line where it is defined.
There are some interesting and probably related comments in the
same file about the Linux netback driver's lacking capabilities of
handling many fragments. But why do we care about that when receiving?
I would guestimate that either max should be higher than what it
currently is (5) or the check which produces the error might be
unneeded.
