Hi
Would you consider making the PhyLink modifications to the Altera TSE
driver public as this would be very useful for a board we have which
uses an SFP PHY connected to the TSE core via I2C. Currently we are
using a fibre SFP and fixing the speed to 1G but would really like to be
able to use a copper SFP which needs to do negotiation.
Cheers

All right, the first message got ignored so this is my take two. :)
Has anyone stumbled on the same problem as me?

Hi Thor,
In my effort to move Altera TSE driver from PHYLIB to PHYLINK i ran into a
problem. The driver would not work properly on 100Mbit/s links. This is true
for the original driver in linux-5.4.y as well as for my PHYLINK/SFP enabled
version.
This is a DT fragment of what i've been trying with 5.4.y kernels and the
stock driver:
tse_sub_2: ethernet@0xc0300000 {
status = "disabled";
compatible = "altr,tse-msgdma-1.0";
reg = <0xc0300000 0x00000400>,
<0xc0301000 0x00000020>,
<0xc0302000 0x00000020>,
<0xc0303000 0x00000008>,
<0xc0304000 0x00000020>,
<0xc0305000 0x00000020>;
reg-names = "control_port", "rx_csr", "rx_desc", "rx_resp",
"tx_csr", "tx_desc";
interrupt-parent =< &intc >;
interrupts = <0 54 4>, <0 55 4>;
interrupt-names = "rx_irq", "tx_irq";
rx-fifo-depth = <2048>;
tx-fifo-depth = <2048>;
address-bits = <48>;
max-frame-size = <1500>;
local-mac-address = [ 00 0C ED 00 00 06 ];
altr,has-supplementary-unicast;
altr,has-hash-multicast-filter;
phy-handle = <0>;
fixed-link {
speed = <1000>;
full-duplex;
};
};
Trying "speed = <100>;" above also doesn't change much, except that the link is
reported (as expected) as 100Mbps.
With the PHYLINK code the above fragment is pretty much the same except for:
sfp = <&sfp0>;
phy-mode = "sgmii";
managed = "in-band-status";
Both (old and new) drivers are working fine on 1Gbps links with optics and
copper SFPs. With PHYLINK code (and in auto-negotiation mode) the link speed
and duplex is properly detected as 100Mbps. MAC and PCS also look correctly set
up, but the device is still unable to receive or transmit packages.
Please let me know should you need more details.
thanks,
Petko
