<rjo> whitequark: the phaser startup kernel freezes when run as a startup kernel from flash. but it works fine if i run it as a regular kernel. any ideas where i could look?
<rjo> whitequark: this is phaser2, after merging current master.

<rjo> whitequark: what is it with r16 and pc/lr in this asm? http://hastebin.com/inececekes.css
<whitequark> that's PIC base register
<whitequark> did it not freeze before rtio.rs merge?
<rjo> froze as well.
<whitequark> ok
<whitequark> did you try inserting core_log statements to see where it freezes?
<rjo> will do.
<rjo> whitequark: it gets to the end. it just doesn't seem to exit.
<whitequark> oh
<rjo> i.e. attribute writeback maybe.
<whitequark> no, that doesn't have any. but i do have an idea
<whitequark> can you remove features=["max_level_debug" ] from Cargo.toml and rebuild?
<whitequark> this will show you at which request it fails

<sb0> whitequark, can we put more RAM in the buildserver or is it maxed out?
rohitksingh has joined #m-labs
<sb0> asus website says that mobo can take 16GB
<sb0> now, do I add more RAM, or replace the mobo entirely for one with a faster CPU?
rohitksingh has quit [Ping timeout: 240 seconds]
<sb0> i can also replace just the cpu... there are core-i7s in compatible packages
<sb0> of course, not all cpus in that package are supported
<sb0> phew
rohitksingh has joined #m-labs
<whitequark> sb0: imo replace the mobo
<sb0> I can put a i7 4790K on that one
<whitequark> hm
<whitequark> 4 cores, 8M of cache
<sb0> it's the same even for the latest ones, it seems
<bb-m-labs> build #223 of artiq-board is complete: Success [build successful] Build details are at http://buildbot.m-labs.hk/builders/artiq-board/builds/223
<sb0> intel i7 marketing: "Today’s PCs are more hassle-free than ever"
<cr1901_modern> Why does it feel like building your own PC in 2016 is a clusterf***?
<sb0> I was actually rambling about this clusterfuck of incompatible cpu packages and mobos
<cr1901_modern> Oh wow, we have identical opinions on this lol
<cr1901_modern> Ngl, I will need a new computer sooner or later, and I'm clueless about balancing price and computer power. My current laptop was high end/a gift when I got it (2011) and I doubt I can afford something of equivalent quality in 2016.
<rjo> whitequark, sb0: looking the graphs and the logs, a few GB of RAM would go a long way in helping the poor old lab machine when running vivado.
<rjo> whitequark: thanks.
<rjo> sb0: ah i see you had the same thought.
<rjo> cr1901_modern: did you just preemptively self-censor?
rohitksingh has quit [Quit: Leaving.]
<cr1901_modern> rjo: Yes. It's a habit from days of old where ppl who might want to hire me might not want to see gratuitous use of "fuck" on Twitter
<cr1901_modern> I should prob get out of the habit, b/c at this point my Bird Website profile is part of my public persona
<rjo> independent of whether one considers that language appropriate or inapproriate: the idea that masking words using *** or bleeps or blurs could somehow "un-say" them is a genuinely absurd one.
<rjo> whitequark: i can't find features=["max_level_debug" ] anywhere
<bb-m-labs> build #1120 of artiq is complete: Failure [failed python_unittest_1] Build details are at http://buildbot.m-labs.hk/builders/artiq/builds/1120 blamelist: Sebastien Bourdeauducq <sb@m-labs.hk>
<cr1901_modern> rjo: I never said it was a rational habit :P.
<cr1901_modern> It's just one that I have, and getting rid of it, to be free of the reins of inappropriate language, is tough
<cr1901_modern> It's like the people who press the don't walk button at a traffic light crossing, despite it not doing anything
rohitksingh has joined #m-labs
<rjo> whitequark: found it.
<whitequark> cr1901_modern: that's actually a US thing
<whitequark> in HK, elevator door close buttons and traffic crossing buttons mostly actually do what they are supposed to, for example
<cr1901_modern> whitequark: Interesing! TIL... wonder why the difference
<whitequark> supposedly in the US they also used to work, but then traffic increased
<whitequark> and no one wanted to pay for demounting the buttons that are on every intersection
<whitequark> whereas in HK there aren't that many in the first place
<whitequark> as for elevators, well, your country has stupid customs :p
rohitksingh has quit [Quit: Leaving.]
<cr1901_modern> I remember hearing that in China, 4 is the number of death, so it's custom for elevators to skip that floor out of custom.
<rjo> here in germany most elevator buttons also actually close doors. same for pedestrian crossings.
<rjo> cr1901_modern: come to germany!
<cr1901_modern> rjo: If things here get bad enough, I may consider that invitation lol
<whitequark> it was hard enough to emigrate to germany five years ago...
<rjo> whitequark: i guess the country of origin might matter.
<rjo> whitequark: removing that max_debug_level feature does not change the boot log output.

<whitequark> let me double-check something
<sb0> whitequark, are you using the kc705?
<whitequark> sb0: yes
<whitequark> will stop soon
<sb0> okay let me take the aux one
<rjo> whitequark: yes. i am loading the new runtime each time.
<sb0> did you figure which ttyUSB it is on?
<rjo> sb0: i am on that one.
<rjo> but i can vacate it if you need it now.
<sb0> i'll wait
<rjo> sb0: go ahead. it's yours.
<sb0> rjo, which tty?
<whitequark> sb0: are you running the phaser branch on kc705?
<rjo> sb0: /dev/serial/by-id/usb-Silicon_Labs_CP2103_USB_to_UART_Bridge_Controller_0001-if00-port0
<sb0> whitequark, I'm running the drtio branch on aux, and I'm not flashing anything, just loading bitstreams into fpga sram and runtime with flterm
