<azonenberg_work> Oh great
<azonenberg_work> Just what i need
<azonenberg_work> Took a bit of time away from work to rip out the 1st floor hallway at the new place
<azonenberg_work> Aaaand seems like there's popcorn ceiling in the hallway hidden behind a second layer of sheetrock
<azonenberg_work> That the asbestos inspector didn't see
<rqou> eh, just vacuum it up :P
<rqou> what's "abatement?" :P :P

<azonenberg_work> lol
<rqou> btw, my parents' house has a non-asbestos popcorn ceiling, so you might be lucky?
<azonenberg_work> Our ceiling upstairs tested positive
<azonenberg_work> in the closets
<rqou> oh, so you already need asbestos abatement anyways
<azonenberg_work> welll
<azonenberg_work> I thought that's all there was (the rest of the ceilings upstairs had traces but below regulated limits, the downstairs was undetectable
<azonenberg_work> Upstairs ceilings: formerly popcorned, mostly removed (some traces but below regulated limits)
<azonenberg_work> Downstairs remaining ceilings: below detectable levels
<rqou> i thought "below regulated limits" was still bad?
<azonenberg_work> It is, but it means it's not a hazmat if i chuck it myself :p
<rqou> ah lol
<rqou> i'm not even sure my normal respirator is suitable or not
<azonenberg_work> I'm wearing a tyvek bunny suit and P100 respirator for sheetrock demo in general so i'm not super concerned about a few traces
<azonenberg_work> My original plan was to RFQ for abatement of the closets, but most likely just mount a second layer of drywall over them and encapsulate them
<azonenberg_work> i'd have to disclose if/when i sold the place but it would be sealed in and unable to leak fibers or be accidentally damaged
<rqou> btw is a p100 filter actually good enough?
<azonenberg_work> Yes
<azonenberg_work> I'd want to clean-shave to get a good fit though
<rqou> just be asian and there won't be a problem anymore :P
<azonenberg_work> I shortened my beard to make the respirator fit better when doing sheetrock demo but didnt bother with a super close shave
<azonenberg_work> because sheetrock dust is nuisance dust, not full hazmat
<azonenberg_work> So if a little got in, whatever
<azonenberg_work> anyway, the ceiling downstairs is especially problematic because of the placement right next to the main house hvac intake
<azonenberg_work> So i'm definitely going to want to get that professionally handled
<azonenberg_work> its only about 20 square feet, it shouldnt be too pricey
<azonenberg_work> The closets are each about that big and there's something like 3 or 4 of them
<azonenberg_work> Then the rest of the upstairs is mostly negative but there's a few bumpy spots that tested positive whewre the previous abatement guy was sloppy (guessing it was a DIY job decades ago)
<azonenberg_work> (but below regulated limits)
<azonenberg_work> The only thing i'd consider DIY removal of myself is that
<azonenberg_work> Basically just pull the whole piece of sheetrock down and avoid pulverizing that area
<azonenberg_work> then hepa vac everything to get any residue
<rqou> hmm, wikipedia[citation needed] claims that a hepa vac isn't sufficient

<rqou> wow, amazon's recommendations are totally broken for me
<rqou> it keeps thinking i want to buy bags of sulfur
<rqou> whitequark is this your fault? :P
<qu1j0t3> the feds are trolling you
<qu1j0t3> don't take the bait
<rqou> sulfur isn't illegal?
<qu1j0t3> it's a gateway drug
<sorear> sulfur does not seem to be on the list, but if you burn it and dissolve the vapors in water, that _will_ produce a controlled substance because wtf
<pie__> sorear, oh?
<rqou> wait wtf?
<rqou> but i can buy it at walmart
<rqou> or is that KYC-compliant?
<pie__> this looks badass how have i not seen this yet https://en.wikipedia.org/wiki/Boeing_X-37B

<rqou> azonenberg: can you kick the github bot?
<azonenberg> Why?
<rqou> it's not posting to the channel correctly?
<azonenberg> rqou: that wont help
<azonenberg> it's a github-side issue afaik
<rqou> hmm, ok
<azonenberg> i've had this happen before both here and in other chans
<azonenberg> and i dont have a good solution
<azonenberg> it might also be that whatever freenode server the bot is trying to talk to is down / ddos'd / netsplit
<azonenberg> sorear: it's not controlled like you think when you hear of controlled narcotics
<azonenberg> it's just that they keep an eye on who buys large volumes and purchases above some threshold (which is huge) have to be reported
<azonenberg> The DEA isnt making lists of everyone who buys acetone :p
<azonenberg> i mean maybe they are, but they dont do much with that info b/c the list is so long
<sorear> NSA probably is though :p
<rqou> home depot actually "checked id" last time i went to buy acetone
<azonenberg> :o
<rqou> which was kinda surprising to me
<azonenberg> Honestly
<azonenberg> i think they'd be more concerned about kids making TATP
<azonenberg> than drugs
<azonenberg> :p
<rqou> by "checked id" i meant "the person staffing the self-checkout glanced at me, saw that i obviously wasn't <18 anymore, and didn't actually check my id"
<azonenberg> Yeah exactly
<rqou> yeah, i assume it's because of TATP
<azonenberg> having a 18+ restriction is sensible on easily misused / hazardous things
<azonenberg> making a full log of purchases is a bit more absurd
<rqou> unless you're the UK? :P
<azonenberg> Simply b/c order volume is so high the log is useless
<azonenberg> They dont do that in the UK, do they?
<azonenberg> for acetone?
<azonenberg> if its some unusual hazmat i can understand logging
<sorear> why do you think they're pushing "big data" so hard these days? need innovation to process the surveillance haul
<azonenberg> if somebody buys pure KCN i *want* records of that :p
<rqou> there were rumors that the uk wanted to ban acetone after some of the recent terrorist attacks, and sulfuric acid after some of the recent acid attacks
<azonenberg> lol
<azonenberg> well this is the same UK that, after largely banning private firearm ownership
<rqou> of course this is unlikely to work because sulfuric acid is one of the most widely-used industrial chemicals in the world
<azonenberg> is trying to outlaw long kitchen knives
<azonenberg> this was years ago and i dont think it passed
<sorear> making TATP is a self-punishing activity and criminalizing it is just cruel
<azonenberg> but there was an attempt
<azonenberg> sorear: hey, you get to meet your 47 virgins all right
<azonenberg> It just probably will be long before you get to the target :p
<azonenberg> The more terrorists we have making TATP the better
<azonenberg> because that means they're not making something more stable and effective
<rqou> azonenberg: also, 6+ months later i finally moved the xc2bit tests, happy? :P
<azonenberg> lol
<azonenberg> better late than never
<azonenberg> rqou: how far along is your whole par at this point?
<rqou> azonenberg: needs a lot more tests and documentation on the PAR side but it should "work"
<rqou> needs fixing on the logic optimization side
<azonenberg> Nice
<azonenberg> Do you have docs etc up somewhere in the repo?
<azonenberg> i need to try it some time
<rqou> but i haven't tested anything beyond a trivial example and it's almost guaranteed to hit a bug
<rqou> the last yak i was working on was to make it easier to load internal data structures
<rqou> so that it's easier to test the corner cases i know about
<rqou> also, no docs :P
<rqou> who needs those :P :P

<q3k> does anyone here have experience with reverse engineering IP core parameter generation in Lattice Diamond?
<q3k> I'm trying to find out how PLL parameters are generated based on desired frequencies and phases, and it's difficult to even find the part of the suite responsible for that.
<q3k> (I'm working on the Lattice ECP5 series)
<q3k> okay, looks like the low level tool is called 'suba', which then loads encrypted/compressed data files from diamond/3.9_x64/ispfpga/${arch}/data/{scuba.dat,...}
<q3k> and uses that to generate verilog wrapper, EDIFs, or whatever else
<azonenberg> q3k: I do not have experience with that, honestly i'd rebuild it from scratch
<azonenberg> Finding the set of legal values for a given input/output is easy
<azonenberg> Then you just need a cost function to decide which of the possible options is best
<azonenberg> this just requires some googling and/or testing of parameters to see if you're better off with e.g. higher, lower, or midrange VCO frequency
<azonenberg> or higher/lower/midrange PFD
<azonenberg> etc

<rqou> no, it's "xorg crashed hard"
<rqou> but only the gpu part, not the input part
<jn> that sounds annoying
<rqou> welcome to the Linux desktop?
<rqou> xorg managed to crash and misprogram the gpu, leading to an unending spew of iommu page faults
<rqou> also, gpu crashes are pretty scary
<rqou> how did we survive years of buggy gpus and no iommu?
nrossi has quit [Quit: Connection closed for inactivity]
<Prf_Jakob> rqou: lots of blood sweat and tears from GPU driver writers.
<rqou> does having an iommu really help reduce blood sweat and tears?
<Prf_Jakob> Not that I know of, what helped was moving to PCIe.
<Prf_Jakob> Not deadlocking the PCI bus helped with debugging
<rqou> ah lol
<Prf_Jakob> But there is a reason for the channel topic of #dri-devel being:
<Prf_Jakob> <ajax> nothing involved with X should ever be unable to find a bar
<rqou> are you willing to talk about which chipsets you wrote drivers for?
<Prf_Jakob> Me? I did a little bit work on i915, glanced at the PowerVR SGX and Larrabe. And then worked for VMware on the virtual graphics stack.
<Prf_Jakob> Larrabee*
<rqou> can you confirm or deny that the powervr architecture is a ridiculously-wide vliw with a bazillion delay slots?
<Prf_Jakob> Can do neither, worked just a tiny bit on the 2D core. And we where outside contractors who got handed a shader compiler library that we had to use.
<rqou> ah, ok
<Prf_Jakob> But wouldn't suprise me :)
<rqou> btw, intel poulsbo graphics are a giant pile of shit :P
<Prf_Jakob> That's the thing I worked on.
<Prf_Jakob> And yes
<rqou> i don't even understand why intel picked it
<Prf_Jakob> But for the power usage, and for it's time it's pretty hard to beat
<rqou> was the old not-"hd graphics" intel gma that crappy?
<Prf_Jakob> It sat in a PC with not so much concern for power usage.
<Prf_Jakob> Where the Atom/Pulsbo wanted to go mobil.
<Prf_Jakob> And the amount of tricks and hoops that the SGX does to save power is far more then Intel could ever do.
<rqou> yeah, well it's one of the most ridiculously closed and proprietary so i have no idea how it works
<Prf_Jakob> Basicgist, it's a tiled renderer. And then a bunch of black magic.
<Prf_Jakob> Basic gist*
<rqou> i know the tiled renderer part
<rqou> and basically nothing else
<Prf_Jakob> IIRC they had a tiling format that was in morton order.
<Prf_Jakob> Wish I could help more, but I wasn't really attached to that project.
<balrog> Prf_Jakob: PowerVR SGX... fuuuuun (not)
<balrog> Poulsbo is PVR I think
<Prf_Jakob> Yupp
<Prf_Jakob> Bastard child of Intel and PowerVR.
<rqou> without any working 64-bit drivers
<rqou> even on windows
<sorear> my knowledge of modern GPUs basically stops at having combed over the Gen specs
<sorear> i'd like to know more but so much information isn't published
<sorear> read a neat and enlightening book 15 years ago about the then-early history of graphics accelerators
<Prf_Jakob> Look at the AMD architecture as well
<Prf_Jakob> Since it's all so low level you can figure out most of what the shader core does.
<balrog> and now, intel is working with AMD instead
<sorear> i haven't seen any evidence that they're actually discontinuing gen
<Prf_Jakob> Intel is big and parts often don't know what the other is doing.
<rqou> yeah, i heard intel is particularly bad at that
<Prf_Jakob> Which why I think the whole pulsbo thing turned out so bad. The part that does open source didn't know and have a say in the gfx core they used.
<sorear> intel has two GPUs?
<sorear> ah I see
<pie__> hey rqou im losing my shit over this
<lain> XD
<Prf_Jakob> Haha! :D
<lain> >From what has been presented in this preliminary work, it is safe to conclude that the phrase “Flat is Justice” is deficient aerodynamically.
<lain> this is the best thing I've ever read in my life
<awygle> Oh my lord that's incredible
<q3k> azonenberg: you might be right... I'll probably give it a day max before I do it your way, black box.
<q3k> azonenberg: software archeology is interseting though. some of the libraries used by diamond yield some xilinx coregen-related forum issues
<q3k> azonenberg: (libbas{pm,ut,...}.{dll,so})
<q3k> seems to be a NeoCAD thing, heh
