<openfpga-github> openfpga/master 49aa66e Andrew Zonenberg: Finished support for separating counters with 4- and 3-bit input muxes. This means that RC oscillator pre-divider value of 12 now works reliably without needing LOC constraints. Fixes #83.

<azonenberg> not sure if i have the stuff you needed yet
<azonenberg> DCMP/PWM and DAC are my current focus and i hope to have counters driving PWMs in the next few hours
<azonenberg> sorry i meant
<azonenberg> counters driving DACs

<openfpga-github> [openfpga] cyrozap commented on issue #84: @rqou `TAG+="uaccess"` is for systemd compatibility and `MODE="660", GROUP="plugdev"` is for non-systemd systems. This is the same pattern OpenOCD uses for [its udev rules](http://repo.or.cz/openocd.git/blob/HEAD:/contrib/60-openocd.rules). https://git.io/vHTXB

<rqou> cyrozap: can you explain what "uaccess" actually does? I searched on google briefly and there are results saying it should be used, but no explanation of why plugdev is insufficient
<rqou> on my systems, i only have "plugdev" rules and everything seems to work
<rqou> (under systemd)

<azonenberg> cyrozap: me and rqou are having a bit of a hackathon at my place this weekend
<azonenberg> have you looked at the commit log? lol
<cyrozap> rqou: uaccess has to do with adding permissions based on systemd "seats" (or something like that)
<cyrozap> azonenberg: Oh, lol
<rqou> cyrozap: so is uaccess just "magic?"
<rqou> as in systemd has some special logic for it?
<cyrozap> rqou: Basically, uaccess gives access to any user session where the user can be considered physically present, i.e., at the keyboard, and excludes sessions where the user is, say, connected via ssh.
<rqou> but that's exactly what I don't want
<cyrozap> rqou: It's not magic, I just don't remember how it works.
<cyrozap> Then use plugdev :P
<rqou> so plugdev doesn't stop working?
<cyrozap> Correct.
<rqou> the only explanation of uaccess i could find was some minor flaming on the redhat bugzilla where some application developer was asking "wtf is happening?" and kay sievers just said "ignore him, do it our way" without explaining the rationale
<rqou> but if plugdev continues to work, then this is fine
<cyrozap> The idea for these rules is that they're sane defaults for most use cases. e.g., if I give someone ssh access to a machine connected to a bunch of hardware, I don't necessarily want them to have access to all of that, but if they're sitting at the machine, they already have physical access, so it makes sense to let them have permission to access it.
<rqou> i can see how that makes sense
<cyrozap> That's the rationale behind uaccess, at least.
<rqou> this doesn't seem to be clearly explained anywhere
<cyrozap> Welcome to the wonderful world of systemd :P
<cyrozap> Anyways, if you want special permissions for certain users, you can always add your own udev rules.
<rqou> so if you have both like in your case, both the "systemd seat" users and the plugdev users have access?
<cyrozap> Correct.
<rqou> ah ok
<cyrozap> Permissions are restrictive by default (only root has access), so udev rules exist to give non-root users permission to access hardware.

<rqou> i know that, but i normally just used unix groups to manage permissions
<rqou> not the uaccess mechanism
<cyrozap> Yeah, that's what I used to do, too, but this makes it more convenient for casual Linux users to just "plug-and-play" (like on certain other desktop OSes) instead of having to muck about with groups and permissions.
<cyrozap> And of course you can always override these rules with your own.

<cr1901_modern> rqou: It enables some printf control codes that don't work on Windows normally. I enabled it to quell some compiler bitching IIRC
<rqou> can you please check it again? there's still compiler format string warnings on Windows
<rqou> I mean, it works
<rqou> but some diagnostics might be busted on Windows

<pie_> you guys know a chip decapping protocol written down somewhere so i can ask around if anyone in the chemistry department is willing to help me? like in the form of a proper paper or something, maybe they'll take me seriously
<rqou> egg|egg: very frustratingly
<azonenberg> that good enough? talks about a couple of approaches including live and bare die nitric
<pie_> i was hoping for like a short academicis paper, but i know you have those :) ill take a look again
