<lkcl> whitequark: before i discovered the bool() method, here's an illustration of how expressions can go horribly wrong
<lkcl> https://git.libre-riscv.org/?p=crowdsupply.git;a=blob;f=images/align_single_fail.png;h=e4004eb02eb89448b9744d9cbdd29e546efc2813;hb=c756d2f8b95bfc84305d04dfb639533528655e2d
<lkcl> :)
<lkcl> that's *twenty five* copies of a variable-bit-length shift
<lkcl> 25 copies because a 32-bit FP mantissa is 24 bits
<lkcl> it would be over fifty for a 64-bit FP number!
<lkcl> this the deceptive innocuous-looking code that generated that pigsty mess:
<lkcl> https://git.libre-riscv.org/?p=crowdsupply.git;a=blob;f=images/shift_screenshot.png;h=17fab04f4b77218d126a6079c2f7e3c28d8c56f5;hb=c756d2f8b95bfc84305d04dfb639533528655e2d
<lkcl> MultiShift is just a << b

<sb0> _florent_: how exactly did you test GTH Ethernet?
<sb0> it just won't work on sayma.
<_florent_> sb0: here is what i tested on the KCU105: https://hastebin.com/omuramusuv.pl
<_florent_> sb0: it was working (responding to ping) with clock from fabric or with 125MHz clock from the SI570
<sb0> ffs
<sb0> *original* misoc code?
<sb0> there is just no link here
<rjo> sb0: the aaaa entry for lab.m-labs.hk is wrong. could you set it?
<sb0> rjo: what's the correct value?
<rjo> sb0: 2002:2ac8:93ab:0:a60:6eff:fe44:4295
<sb0> is ipv6 working at all? it's just something that you/whitequark set up and never saw working actually
<rjo> sure. has been working just fine until the ipv4 changed.
<rjo> well. has always been working fine. just the ipv6 changed in response to the ipv4 change.
<rjo> only the dns entry is still the old one.
<sb0> ok I have updated it
<_florent_> sb0: i haven't tested with misoc directly, but the way it's instanciated will be the same
<whitequark> i set it up, it uses ipv4 tunneling
<whitequark> somewhat surprised it worked well
<whitequark> i guess the hk networks are less hostile to 6-in-4
<whitequark> (or was it 6-to-4?)
<rjo> sb0: it's still the old entry in DNS. also on the authoritative NS. update the serial?
<sb0> rjo: i've already updated the serial, iirc there's a cronjob that re-reads the file on the server, it should get updated later
<sb0> hmm with the other board it's not receiving trash data (but still no link)
<sb0> when connected to kasli ...
<sb0> so there's some progress
<sb0> _florent_: how many times did you test it - could it be some intermittent bug? what was at the other end?
<_florent_> sb0: i did several tests but extensively. While doing it, it was always working. I tested with SFP to Ethernet module and it was connected to a 1Gbps Ethernet switch.
