<wolfspraul>
so embarassing. I have two serious customers who are thinking about or have already bought an m1, and I know there is a > 80% chance they will regret their purchase later and/or sooner or later run into such a long list of frustrating bugs and missing features that they will just give up.
<wolfspraul>
my job is to give them some fake support before this 'give up' and get them to the point that they at least don't want their money back and think "ok, I was stupid in buying this"
<wolfspraul>
great work :-)

how not to run an enterprise, rule #2: put a pessimist in charge of marketing and sales :)
<wolfspraul>
I will try to sell m1 to them, and i will cordially invite them to this channel
<wolfspraul>
then I have the right problem in front of me making them happy, rather than discussing random new tech features
<wolfspraul>
:-)
<wolfspraul>
there's the optimist! :-)

that sounds better :)
<wolfspraul>
larsc said migen is an "ast generator" - what is ast? abstract syntax tree?
<wolfspraul>
and what's the point, or rather difference between an "ast generator" and "language"?
<Jia>
AST is abstract syntax tree, yes. But AST is not language.
<Jia>
FE have a AST generator
<wolfspraul>
ah Jia, hi :-)
<wolfspraul>
I don't understand the difference between "ast generator" and "language" and the point lars was trying to make
<Jia>
make what? a new compiler?
<wolfspraul>
it was in reference to migen
<Jia>
lars must be a man, I think :-)
<wolfspraul>
any update on the gcc-lm32 bugs you looked into?
<Jia>
I'm just back when I finish qemu-or32.
<Jia>
I nerver giev up fix gcc-lm32. and I'm still working on it.

wolfspraul: and what do you expect from these two people?
Jia has joined #milkymist
<wolfspraul>
expect? I would hope that m1 satisfies them.
<wolfspraul>
obviously
<wolfspraul>
or maybe m1 is depression training?
<wpwrak>
maybe one of them is a magic frog, waiting to be awakened by a kiss from M1. then he'll be eternally grateful and grant you everlasting fame, mountains of gold, and beautiful princesses :)

lekernel: what's your plan about milkymist-ng and mmu exactly ?
Gurty` has quit [Ping timeout: 244 seconds]
Jia has quit [Quit: Konversation terminated!]
<lekernel>
well, the only big plans that I have are about -ng. it will replace the current soc at some point.
<wolfspraul>
I don't really see that on m1
<wolfspraul>
it sounds like many m1 features will not work, and some are hard to represent via -ng? or am I wrong?
<wolfspraul>
we just wait and see

<lekernel>
just reuse the legacy verilog code
<lekernel>
this is much simpler than reverse engineering fpga architectures and bitstream formats by the way ...
<lekernel>
so, unless you're not convinced that -ng will work or brings any benefit at all, "wait and see" doesn't exactly sound like the right thing to do

lekernel: I mean what do you plan using the MMU for on milkymist-ng ? Running Linux ?
<lekernel>
not me - but nevertheless, the current soc will become obsolete.
<lekernel>
unless you insist that MM should have slow memory, difficult to connect buses, low video resolution, etc.
<Fallenou>
sure I would rather use milkymist-ng on M1
<Fallenou>
if it's not too difficult to integrate all the other cores (for instance those doing DMA on FML)
cladamw has joined #milkymist
<lekernel>
there's only video-in
<Fallenou>
ok so upgrading M1 to milkymist-ng would only break video-in feature ?

<lekernel>
if someone ports the other cores (midi, dmx, etc.), yes
<lekernel>
which are quite easy to port
<lekernel>
what I'll do for -ng on m1 is read-only flash, uart, ddr, vga, ethernet, tmu, and usb. probably nothing else.
<lekernel>
oh and dvi on r4

<kristianpaul>
obsolete if migen aceptance is high.. have anyone check google trends latelly? ;-)
<kristianpaul>
also rtems still just suported on the legacy m1 soc :), i'm not agaisnt lua, but for wider porpuses it may get hang
<lekernel>
then port it or use bare metal or linux
