May 19 03:02:26 <set_> Okay. I will get the footage but play it safe w/ your excitement!
May 19 03:26:21 <set_> negative feedback. Please hold.
May 19 03:32:18 <set_> it would help if I started the .service file. Yikes.
May 19 03:32:54 <set_> I do not think I ever pushed the return key any harder in my life. Bang, bang, bang.
May 19 03:32:54 <set_> Ha.
May 19 03:35:20 <set_> Whelp, I got all kinds of issues now. Please hold for your viewing pleasure. Give it around 15 minutes before the bugs come back.
May 19 03:41:58 <set_> Up and runnin' and bugs galore. Let me see if I can save this file on my BBB.
May 19 04:03:24 <set_> Oh well. I have an internal server error now. Forget it. I goofed again.
May 19 05:19:54 <set_> Better late than never! The bot lives on but the cool of the night has made the bugs recede.
May 19 05:20:09 <set_> So, we shall get w/ it on a later date.
May 19 05:20:17 <set_> On live the bugs!
May 19 13:11:41 <yates> when setting the monitor vector base address register (MVBAR), should the address be the physical address or the virtual address if that area of memory has an address translation?
May 19 13:12:29 <mru> lazy answer: set an identity mapping and forget about it
May 19 13:13:01 <yates> if it were my code i might do just that...
May 19 13:14:34 <mru> not quite as lazy answer: try and find out
May 19 13:14:37 <bbblob> Is anybody aware of an enclousure/housing for the beagleboard-x15?
May 19 13:14:48 <mru> might be quicker than finding the answer in the manuals
May 19 13:16:32 <zmatt> yates: it's used as an address to jump to, so how on earth could it be physical?
May 19 13:17:44 <yates> it depends on the hardware. i could certainly postulate a scenario.
May 19 13:18:20 <yates> s/it depends/it could depend/
May 19 13:18:22 <zmatt> I'd love to hear it.  the only way a branch target could be a physical address is if there's no virtual addressing in the first place, in which case the question is moot
May 19 13:21:06 <mru> suggest it to intel
May 19 13:21:10 <mru> I'm sure they can find a way
May 19 13:22:00 <zmatt> taking an exception means, in essence, switching processor mode (while saving the old one) and performing a branch-and-link to the VBAR/MVBAR address + an exception-dependent small offset
May 19 13:22:43 <zmatt> so VBAR/MVBAR is a branch target hence inherently uses whatever address space is used for instruction fetch
May 19 13:22:53 <mru> in that mode
May 19 13:22:58 <zmatt> in that mode
May 19 13:23:14 <mru> which in principle could be physical
May 19 13:23:17 <mru> but probably isn't here
May 19 13:23:33 <zmatt> it could be physical if virtual and physical are the same thing in that mode :P
May 19 13:23:46 <mru> back to my first "answer"
May 19 13:24:10 <zmatt> yeah I've only used identity mapping in my baremetal code, because lazy
May 19 23:37:23 <set_> BELA already has six lectures of videos. I turn my back for one second and bam, BELAs' already done a lot.
May 20 00:10:13 <GenTooMan> set_ urpdate https://embeddedemulation.blogspot.com/2020/05/may-finally.html
May 20 00:44:45 <set_> Nice.
May 20 00:45:22 <set_> I totally forgot about the Greenpeace/OSHW thing.
May 20 00:45:32 <set_> So?
May 20 00:45:37 <set_> Are you going to produce it?
May 20 01:15:43 <GenTooMan> need heat sink
May 20 01:28:24 <set_> Get one!
May 20 01:29:09 <GenTooMan> The right one is the issue. In simple words "It's complicated"
May 20 01:34:30 <set_> 4 x 4 x ___ mm?
May 20 01:34:58 <set_> Or...does it need to have to be cnc'ed w/ arms and legs?
May 20 01:36:57 <GenTooMan> 3x4 x? height neecd to do thermal calculations then find proper spacers so it doesn't crush things etc
May 20 01:37:32 <set_> Oh. Okay.
May 20 01:38:26 <set_> Yep.
May 20 01:39:55 <set_> So, how would you perform thermal calculations on a piece of metal?
May 20 01:40:06 <set_> Thirmister?
May 20 01:44:51 <GenTooMan> First you compute how much power you are going to loose worst case then each stage of thermal impedance then lastly you have your thermal resistance you need
May 20 01:47:14 <set_> Oh. Hmm. That sounds oddly interesting. So, the thermal "grease" needs to be tested w/ a calculation of impedance and resistance.
May 20 01:48:44 <set_> I guess things take time. I am cyclic in my ideas too. I start, stop, reconvene, and over again on my projects.
May 20 01:49:14 <set_> "Until completion" = sometimes
May 20 02:08:16 <GenTooMan> complete is sometimes subjective or often
May 20 02:09:38 <set_> Anyway, like all good things, I must bite the dust. Poof.
May 20 02:09:52 <set_> See 'ya later!
