net: cpsw: am335x: Drop constant link checking from rx/tx path's

We noticed on the DXR2 platform (AM335x with a SMSC LAN9303 switch connected
to the CPSW MAC) that the network performance in U-Boot is quite poor. Only
when the transfer is started without a cable connected, and the cable is
plugged after the first timeout "T" occured, an increased in performance
can be seen. Debugging has revealed, that the cpsw driver has constant
link checking builtin into the rx and tx functions. This results in the
bad performance and seems to be unnecessary. The link has already been
checked in the init function, before the transfer is started. This usually
is sufficient.

BTW: I have seen no other network driver in U-Boot so far, that constantly
checks for link in the rx / tx functions.

The performance numbers on the DXR2 board are:

0.56 MiB/s cpsw_check_link() in rx and tx path
0.87 MiB/s cpsw_check_link() only in tx path
1.0  MiB/s cpsw_check_link() only in rx path
2.7  MiB/s no cpsw_check_link() in rx and tx path

So with this patch the network performance on DXR2 increases from 0.56
to 2.7 MiB/s (nearly 5 times as fast).

10 years agonios2: Fix printf size_t format related warnings (again...)
Vasili Galka [Thu, 14 Aug 2014 14:42:05 +0000 (17:42 +0300)]
nios2: Fix printf size_t format related warnings (again...)

When compiling the current code on GCC 4.8.3, the following warnings
appear:

warning: format '%zu' expects argument of type 'size_t', but argument
2 has type 'long unsigned int' [-Wformat=]

There were many mails about such warnings on different architectures.
This patch limits itself to the nios2 architecture.

The problem is that for the size_t (%zu, %zd, ...) arguments of
printf GCC does not verify the type match to size_t type. It verifies
the type match to the compiler-defined __SIZE_TYPE__ type. Thus, if
size_t is defined different from __SIZE_TYPE__ - warnings inevitably
appear.

There is a comment by Thomas Chou to the (rejected) patch:
http://patchwork.ozlabs.org/patch/272102/
which explains that the older GCC toolchains (gcc-3.4.6 and gcc-4.1.2)
expect size_t to be "unsigned long" and the newer expect it to be
"unsigned int". Thus, no matter how we define size_t - either way
warnings appear when using some GCC version.

By rejecting that patch, a choice was made to prefer older GCC versions
and leave the warnings when building with the newer toolchains.
Personally, I disagree with this choice...

In any case, this patch proposes a way to fix the warnings for any GCC
version. Just define size_t using the __SIZE_TYPE__ compiler-defined
type and the type verification will pass.

I tested that this fixes the warning on GCC 4.8.3. I don't have an
older toolchain to test with, but __SIZE_TYPE__ was definitely defined
in GCC 3.4.6, so it should work there too.

10 years agonet: More BOOTP retry timeout improvements
Thierry Reding [Tue, 19 Aug 2014 08:21:24 +0000 (10:21 +0200)]
net: More BOOTP retry timeout improvements

It's not unusual for DHCP servers to take a couple hundred milliseconds
to respond to DHCP discover messages. One possible reason for the delay
can be that the server checks (typically using an ARP request) that the
IP it's about to hand out isn't in use yet. To make matters worse, some
servers may also queue up requests and process them sequentially, which
can cause excessively long delays if clients retry too fast.

Commit f59be6e850b3 ("net: BOOTP retry timeout improvements") shortened
the retry timeouts significantly, but the BOOTP/DHCP implementation in
U-Boot doesn't handle that well because it will ignore incoming replies
to earlier requests. In one particular setup this increases the time it
takes to obtain a DHCP lease from 630 ms to 8313 ms.

This commit attempts to fix this in two ways. First it increases the
initial retry timeout from 10 ms to 250 ms to give DHCP servers some
more time to respond. At the same time a cache of outstanding DHCP
request IDs is kept so that the implementation will know to continue
transactions even after a retransmission of the DISCOVER message. The
maximum retry timeout is also increased from 1 second to 2 seconds. An
ID cache of size 4 will keep DHCP requests around for 8 seconds (once
the maximum retry timeout has been reached) before dropping them. This
should give servers plenty of time to respond. If it ever turns out
that this isn't enough, the size of the cache can easily be increased.

With this commit the DHCP lease on the above-mentioned setup still takes
longer (1230 ms) than originally, but that's an acceptable compromise to
improve DHCP lease acquisition time for a broader range of setups.

To make it easier to benchmark DHCP in the future, this commit also adds
the time it took to obtain a lease to the final "DHCP client bound to
address x.x.x.x" message.

kmp204x: reset the Zarlink clocking chips at power up only

There is the requirement on the chassis's backplane that when the clocks
have been enabled, they then should not disappear.

Resetting the Zarlink clocking chips at unit reset violates this
requirement because the backplane clocks are not supplied during the
reset time.

To avoid this side effect, both the Zarlink clocking chips are reset
only at power up.

Shaohui Xie [Wed, 13 Aug 2014 10:19:15 +0000 (18:19 +0800)]
powerpc/T4240QDS/eth: some fix for XFI

XFI is supported on T4QDS-XFI board, which removed slot3, and four LANEs
of serdes2 are routed to a SFP+ cages, which to house fiber cable or
direct attach cable(copper), the copper cable is used to emulate the
10GBASE-KR scenario.

So, for XFI usage, there are two scenarios, one will use fiber cable,
another will use copper cable. For fiber cable, there is NO PHY, while
for copper cable, we need to use internal PHY which exist in Serdes to
do auto-negotiation and link training, which implemented in kernel.
We use hwconfig to define cable type for XFI, and fixup dtb based on the
cable type.

For copper cable, set below env in hwconfig:

fsl_10gkr_copper:<10g_mac_name>

the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2. The
four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports,
if a given 10G port will use the copper cable for 10GBASE-KR, set the
<10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be
assumed to be used for the port.

For ex. if four XFI ports will both use copper cable, the hwconfig
should contain:

fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2

For fiber cable:

1. give PHY address to a XFI port, otherwise, the XFI ports will not be
available in U-boot, there is no PHY physically for XFI when using fiber
cable, this is just to make U-boot happy and we can use the XFI ports
in U-boot.
2. fixup dtb to use fixed-link in case of fiber cable which has no PHY.
Kernel requests that a MAC must have a PHY or fixed-link.

When using XFI protocol, the MAC 9/10 on FM1 should init as 10G interface.

Change serdes 2 protocol 56 to 55 which has same feature as 56 since 56
is not valid any longer.
