00:00:00 --- log: started osdev/18.05.15
00:00:00 <_mjg_> ye, it adds up now
00:00:27 <geist> hmm, wonder how to generally tell if freebsd is using PTI
00:00:31 <_mjg_> you can disable it with /boot/loader.conf: vm.pmap.pti=0
00:00:32 <geist> i know what to grep for on linux
00:00:36 <geist> kk, will try
00:00:49 <_mjg_> ye, i don't know of anything greppable 8/
00:01:05 <_mjg_> but you can sysctl vm.pmap.pti
00:01:12 <geist> yeah for better or worse i do like the text based discovery of what linux is doing
00:01:15 <geist> it's very handy
00:02:00 <_mjg_> hm
00:02:11 <geist> ah now we're talking. 2.18m
00:02:15 <_mjg_> how about i compile a fresh head kernel for you
00:02:24 <geist> sure, if you'd like
00:02:44 <geist> btw i recommend getting one of these atom machines. they're great low end 64bit machines to test stuff on
00:02:54 <geist> about the dumbest x86-64 you can get. supports almost no features
00:03:00 <geist> but still dual core + HT
00:03:53 <geist> early atom too (bonnell) before they redesigned the core to be OOO (goldmont)
00:04:01 <_mjg_> do they have vt?
00:04:16 <geist> what is vt in this context?
00:04:25 <_mjg_> virt
00:04:28 <geist> virt what?
00:04:54 <geist> and who is 'they'?
00:05:36 <_mjg_> atom cpus, do they include support for virtualisation
00:05:56 <geist> ah. good question. most likely no. lemme see
00:06:10 <geist> nope
00:06:14 <geist> https://ark.intel.com/products/35641/Intel-Atom-Processor-330-1M-Cache-1_60-GHz-533-MHz-FSB
00:06:15 <bslsk05> ark.intel.com: Intel Atom® Processor 330 (1M Cache, 1.60 GHz, 533 MHz FSB) Product Specifications
00:06:16 <_mjg_> i can probably get some atom boxes at work, but bare metal i can only boot linux
00:06:41 --- join: zeus1 (~zeus@197.239.5.128) joined #osdev
00:07:20 --- nick: GynDream -> Gynvael
00:07:37 <_mjg_> compiled the kernel, uploading
00:08:12 <_mjg_> it should boot no problem with release usersapce
00:08:37 <_mjg_> you can use it with 'nextboot' or cd /boot; mv kernel kernel.old
00:08:40 <_mjg_> and unpack the sucker
00:08:48 <_mjg_> then the loader will let you select the new or old one
00:08:56 <geist> kk
00:09:35 <geist> ah never looked into modern freebsd kernel modules. putting them all in one dir like that makes total sense
00:09:51 <geist> most of my 'compile the kernel' memory comes from the 4.x days back when i had a server box
00:10:05 <_mjg_> https://people.freebsd.org/~mjg/.junk/head-boot_kernel.tgz
00:10:28 <_mjg_> will unpack itself as boot/kernel
00:10:38 <geist> kk
00:10:55 <_mjg_> it still will be slow, but should close a lot of the gap
00:11:38 <_mjg_> alas, it does make fbsd even for me with the old linux kernel on nehalem
00:12:07 <_mjg_> someone else tested linux vs fbsd on a modern box and fbsd was 15% or so behind
00:12:49 <_mjg_> that said ye, the /boot/kernel thing i happen to like a lot
00:12:52 <geist> 2.7m
00:12:56 <geist> vs 2.1
00:13:01 <_mjg_> nice
00:13:06 <_mjg_> can you pmcstat the sucker
00:13:08 <geist> not quite 3.5m, but getting that
00:13:10 <geist> sure
00:13:41 <_mjg_> i hoped for a result closer to 3, but what can ya do
00:13:59 <_mjg_> the code has pessimisations like through func calls through function pointers
00:14:00 <_mjg_> :[
00:14:32 <geist> https://pastebin.com/LUCbvmpx
00:14:45 <geist> no bcopy in there though
00:15:09 <geist> what cores is it sampling there? is that a mix of all of them?
00:15:19 <_mjg_> ye, that was turned into an inlined memset
00:15:23 <_mjg_> erm, memmove
00:15:34 <_mjg_> cpu_fetch_syscall_args and the other sucker are not easily fixable
00:15:37 <_mjg_> and are major crappers
00:15:43 --- quit: dbittman_ (Ping timeout: 240 seconds)
00:15:50 <_mjg_> it is sampling everything, hence why high cpu_idle
00:16:03 <geist> across all cores, i assume. so since half of them are probably idle
00:16:08 <_mjg_> yea
00:16:22 <_mjg_> the tool is rather buggy, so trying to get anything fancy is not a good diea
00:16:37 <_mjg_> like limiting reported samples to the target proc
00:16:49 <_mjg_> for rather mundane definitions of fancy
00:16:56 <_mjg_> thanks for testing
00:17:00 <geist> sure thing
00:17:21 <geist> incidentally when i rebooted just a minute ago the kernel clearly paniced hard and spewed pages of garbage before restarting
00:17:27 <geist> so dunno what happened there
00:17:32 <_mjg_> heh
00:18:14 <geist> hmm, lets see what netbsd does
00:18:36 <_mjg_> are you netbooting this?
00:18:38 <_mjg_> pendrive?
00:18:46 <geist> no i just multi installed a whiel back for lulz
00:18:52 <_mjg_> solid
00:19:07 <_mjg_> i would call you a nerd, but had a similar thing going
00:19:15 <_mjg_> can you add illumos into the mix?
00:19:16 <geist> ubuntu is quite good about picking out the boot partitions for other oses, so usually i just do a ubuntu install and then start blatting down additional partitions
00:19:24 <geist> and when you rerun ubuntus update-grub it picks em all up

00:21:27 <geist> hah solid: 3.3m
00:21:32 <geist> netbsd got ya beat
00:21:42 <_mjg_> haha
00:21:57 <_mjg_> that's probably because they don't have the func pointer pessimisation
00:22:25 <_mjg_> you don't get to just fetch the args, you have to use a func... an all abis specify the same one
00:22:28 <_mjg_> well almost all
00:22:42 <_mjg_> but now i havae to fix it, thanks :[
00:22:54 <geist> yah my early zircon syscall dispatch just slammed all the args in the registers and then direct called the C function from asm
00:22:56 --- quit: Arcaelyx (Ping timeout: 265 seconds)
00:23:07 <geist> with the idea is that extra args that were there and ignored by C are harmless
00:23:24 --- quit: NaNkeen (Ping timeout: 276 seconds)
00:23:27 <_mjg_> the sucker here has a dedicated routine to get all the args
00:23:35 <_mjg_> then they all get packed into a struct
00:23:37 <geist> lots of folks got uppity about it, so we ended up building some massive templated monstrosity that i need to go back and unfuck
00:23:53 <_mjg_> and the actual sycalls gets a pair thread pointer + pointer to the struct
00:23:55 <_mjg_> slow as shit
00:23:57 <geist> arm64 it's beautiful too: x0-x7 are first 8 args, all laid out nicely
00:23:58 --- quit: vdamewood (Ping timeout: 255 seconds)
00:24:12 <geist> x16 has the syscall # (though there's like 24 other regs that can be used)
00:24:24 <_mjg_> the latter pessimistaion is present in all the bsds
00:24:25 <geist> so you can basically blat down the callee trashed stuff and direct branch to your C function
00:24:43 <geist> well, via a func pointer though, since you need like one table, right?
00:24:43 <_mjg_> that's what linux is doing most of the time afair
00:24:47 <geist> how else would you do it?
00:25:03 --- quit: zeus1 (Ping timeout: 256 seconds)
00:25:29 <_mjg_> most syscalls take about 3 args, few take up to 6 which is still passable only in regs
00:25:37 <geist> right
00:25:41 <_mjg_> you only need an extra pessimiation for a handful of suckers
00:26:17 <geist> for newos years and years ago i did something odd where i passed the syscall # + number of args in a register
00:26:33 <geist> then the syscall glue just marshalled it via that, then after the fact validated that you gave it the right number of args
00:26:41 <geist> idea was that i avoided a table lookup until yo needed it
00:26:48 <geist> i think? i dunno that was me 20 years ago
00:27:06 <_mjg_> the bsd folks were definitely an odd bunch
00:27:08 <_mjg_> well still are
00:27:27 <_mjg_> there is some questionable stuff (even for the period when it was introduced) made in the name of performance
00:27:42 <geist> it's funny, for zircon i sat down and looked at designing the syscall marshalling mechanism from scratch for x86-64, and then independently came upw ith pretty much precisely the same as linux
00:27:48 <geist> on x86-64 there are only so many ways to do it
00:29:34 <geist> difference is for like 2 calls we used 8 slots, so i have to shove the extra 2 args in funny registers on x86-64
00:29:45 <geist> plus taking into account the syscall instruction, which is annoying
00:31:20 --- join: oaken-source (~oaken-sou@141.89.226.146) joined #osdev
00:31:36 <_mjg_> so what do you have there apart from linux, net and freebsd?
00:31:50 <_mjg_> can you be arsed to install open?
00:31:51 <geist> on this particular machine? that's it
00:31:59 <geist> i was going to do open next and just didn't get to it
00:32:00 <geist> but i can
00:32:23 <_mjg_> in that spirit i would probably try to create a multiboot pendrive
00:32:33 <_mjg_> just boot whatever os is there on whatever machine it got plugged to
00:32:39 <geist> yeah that makes sense though this atom would run like shieeeeeit
00:32:50 <geist> because a) it can't boot from usb properly and b) it has usb 2.0
00:32:59 <_mjg_> huh
00:33:07 <geist> but a is wonky, it's from 2008 so it's bios is a bit crap about booting from usb
00:33:48 <geist> but it can, it's just picky, i think
00:33:55 <geist> it's certainly pre UEFI
00:34:12 <geist> anyway, another day. it's getting late here
00:34:20 --- quit: sprocklem (Quit: brb)
00:34:21 <geist> going to start an 18.04 update and try to get to sleep
00:34:57 <_mjg_> cheers
00:35:10 <_mjg_> i may get some illumos vs linux numbers later this week
00:35:17 --- join: mniip (mniip@freenode/staff/mniip) joined #osdev
00:35:38 <_mjg_> their syscall handler looks decent, it may be it will perform roughly at the same level
00:36:05 --- join: sprocklem (~sprocklem@unaffiliated/sprocklem) joined #osdev
00:36:15 <geist> yah and when i get a chance i'll try to get some fuchsia numbers. we have some test syscalls that i think we have a benchmark of
00:36:19 <geist> but i dont have any numbers handy
00:37:18 <geist> but i'm sure they're fairly bad
00:37:20 <_mjg_> preferably you wouldl test with the same prog
00:37:34 <_mjg_> it has some overhead in the test loop
00:37:45 <xenos1984> geist: are you using the do-release-upgrade way? it frequently bothered me with updated config files, and it turned out that a few things broke because the config file format changed for the new versions in 18.04
00:37:51 <immibis> random philosophical question of the day: is an operating system fundamentally just an architecture specifying the allowed interactions between (abstract) processes?
00:37:59 <geist> _mjg_: yes but we're not posix
00:38:10 <geist> the native syscall interface doesn't really map to this at all
00:38:27 <geist> well, i suppose i could rip out everything but the getuid call and then replace that with the test syscall
00:39:50 <_mjg_> immibis: sounds like something you could discuss at quora (btw, don't)
00:39:59 <immibis> fuck quora
00:40:24 <immibis> (not to be confused with quorra, in which case that statement has an entirely different meaning altogether)
00:40:58 <_mjg_> defo fuck that website 3 times over
00:41:18 <_mjg_> a philofophical question perhaps is if it should be fucked more than stackoverflow
00:41:49 <geist> i dunno i find that maybe 1/5 discussions are interesting
00:42:05 <geist> based on what you filter on at least. lots of military hardware stuff i've found informative
00:42:20 <geist> ie, more objective stuff
00:42:29 <_mjg_> i get a bundle of it-related stuff
00:42:38 <geist> oh that's probably mostly crap
00:42:44 <_mjg_> each subject i'm informed about which is touched there is just fucking terrible
00:42:55 <immibis> it occurred to me today while porting a linux user-space driver to kernel space because "we don't like user-space drivers" - and this is not a reusable driver that has to fit into different hardware configurations, it's just for this one product
00:43:01 <geist> yeah, i can see that. stuff where everyone thinks they're and expert
00:43:15 <_mjg_> geist: some dude asked about linux vs freebsd performance
00:43:16 <immibis> that a microkernel is just linux with all the drivers moved to userspace
00:43:24 <_mjg_> the responses he got where so bad it really me sad
00:43:42 <_mjg_> reciting old myths, linking phoronix benchmarks and other lulz
00:44:17 <geist> fair enough

00:44:43 <_mjg_> i'm giving a special prize to the dude who said that "freebsd was written by academics(..)always has better algorithms"
00:44:47 <geist> xenos1984: i haven't had a problem yet, but then i generally dont tweak stuff too much
00:46:29 <_mjg_> (for someone who is not aware of the subject, freebsd really is not faster. it may be about equal for sme stuff, will be behind at least by few % in most and way behind in a minority)
00:46:29 --- quit: Oxyd76 (Read error: Connection reset by peer)
00:46:45 <_mjg_> if it appears faster for something, there is probably a bug
00:47:03 <geist> right, and things change over time. 15 years ago i'd generally bet much more so on freebsd to be solid vs linux benig more desktopy
00:47:06 <immibis> that person has never looked at academic code
00:47:09 <geist> but really, it's where the momentum is
00:47:34 <_mjg_> 15 years ago fbsd had some real world relevancy
00:47:40 <geist> yah
00:47:44 <_mjg_> and linux was still weirdly hackish
00:47:58 --- join: light2yellow (~l2y@185.220.70.170) joined #osdev
00:48:06 <geist> right. my litmus test at the time was run on a box either with a lot of memory pressure, or under extreme disk io
00:48:15 <geist> and then see which one is actually responsive on the shell
00:48:17 <_mjg_> for years now linux, while not the state of the art, is definitely the most solid general purpose os today
00:48:21 <_mjg_> s/today//
00:48:24 <geist> linux used to just sit there for 10 seconds at a time
00:49:06 <geist> ven then linux i think grew up in the era when heavy swapping is a thing you want to deal with except in extreme conditions
00:49:49 <geist> but yeah, sheer amount of drivers, file systems, modules, etc for linux plus the constant tweaking and moving target, it's pretty nifty, basically
00:50:01 --- join: Oxyd76 (~quassel@5.18.99.0) joined #osdev
00:50:02 <geist> i dread working on it and glad i haven't in a few years, it's no fun codewise at all
00:50:02 <_mjg_> too bad though, around 2009 or so even netbsd seemed like a perfectly reasonable os
00:50:24 --- quit: Oxyd76 (Read error: Connection reset by peer)
00:50:47 <_mjg_> basically everyone fell off the radar, fbsd somewhat keeps up for a number of real-world workloads, but presents no tech reason to use it over linux
00:51:10 <geist> it's like all the architectures that fell by the wayside in the same time frame. now it's just x86 and arm
00:51:20 <geist> OSes it's basically windows and linux. maybe fuchsia will change things a bit
00:51:29 <_mjg_> yea
00:51:30 <geist> i'd certainly love osdev to be more of a real thing
00:51:33 <_mjg_> it is shitty
00:51:42 <_mjg_> to see monoculture
00:52:12 <_mjg_> although from that spirit i'm still a little bit guilty myself. i wouldl have no problem with a unix-like monoculture
00:52:12 <geist> exactly. any monoculture is death to me. i want to buck the trend and have people actually think about osdev, doing something different than just posix, etc
00:52:35 <_mjg_> as long as there are differnt unix-like variants to chose from
00:52:37 <geist> i dont intrinsically hate posix or anything, i just think there are some neat ideas out there
00:52:53 <geist> and yeah that too. as much as folks hate it, at least mac is alive and well
00:53:12 <geist> for now at least. so the bsd stuff still rears its head to folks trying to port some posix code
00:53:30 <geist> 'damnit mac is such a piece of crap' . most of the time it's just doing posix, and code was written assuming linux

06:41:15 <bcos_> t3hn3rd: Almost, yes
06:44:24 <bcos_> t3hn3rd: 1193181.666666 Hz / 1193 = 1,000.1522771718357082984073763621 Hz = 0.99984774601297083721311673457784 ms
06:44:37 <bcos_> ..so "almost 1 ms" is as close as you can get
06:45:22 <t3hn3rd> Ahhh I see, with 1193 being the 16-bit reload value
06:45:42 <t3hn3rd> That makes sense.
06:45:47 <bcos_> Yes - reload value has to be an integer, so...
06:46:16 <t3hn3rd> Absolutely.
06:46:23 <bcos_> To work around that you can do "time += 0.999847746012" each IRQ (e.g. with fixed point maths maybe)
06:47:37 <bcos_> Hrm, maybe "time_in_nanoseconds_since_boot += 999847"
06:47:39 <t3hn3rd> I'll probably just treat the IRQ as 1ms, I only plan on using the PIT for short timestamp-esk tasks, where the tiny drift isn't a massive deal.
06:48:27 <t3hn3rd> Once we need long-term accuracy I'm going to look into the HPET in more detail
06:49:31 <bcos_> For that case; maybe using one-shot mode is better (gets you ~838 nanosecond precision)

06:51:04 <t3hn3rd> Cheers for the clarification though, wanted to make sure I was understanding it correctly before ripping out my co-devs code that he wrote 2 years ago and and replacing it with working code :P
06:51:13 <t3hn3rd> Oooh, that's a decent idea
06:54:35 <bcos_> There's a little trick - if you set the PIT channel to "lobyte only" mode; you can write a new count with a single IO port write (and avoid the overhead of a second IO port write)
06:56:40 <bcos_> (or maybe "hibyte only" mode, which nerfs precision but gives you a much longer maximum)
06:58:26 <t3hn3rd> Heh, will have to play around with the different modes I think! Thanks!

08:48:37 <lkurusa> Hello #osdev
08:48:49 <lkurusa> Hello #osdev!
08:48:51 <lkurusa> oops lagged out
08:51:05 <Vercas> t3hn3rd: Is that a TUI?
08:51:07 <doug16k> t3hn3rd, what I do to solve the PIT precision problem is calculate the number of (actual) nanoseconds between the timer ticks, and advance a nanosecond counter each IRQ. then for a tick of a certain frequency I accumulate those nanoseconds in another counter
08:51:13 <Vercas> Or a really jagged GUI?
08:51:19 <t3hn3rd> Vercas: TUI :P
08:51:32 <Vercas> All in the kernel?
08:52:06 <t3hn3rd> doug16k: Seems like a good solution, I'll keep that in mind, thanks!
08:52:35 <Vercas> t3hn3rd: If you want somewhat easier timing, the RTC can deliver interrupts at 1024 Hz IIRC.
08:52:41 <Vercas> Powers of 2 are easier to deal with.
08:52:57 <t3hn3rd> Vercas: Our OS Design is different to most, so yes, the Window Manager is part of the Kernel for the time being.
08:54:00 <lkurusa> t3hn3rd (IRC): ah the feeling of ping working :-)
08:54:02 <doug16k> t3hn3rd, for example, if the timer IRQ divisor is 12345, then there are 10346284 nanoseconds between IRQs. If I want to get a 1Hz average handler callout, I can accumulate 10346284 to a counter per IRQ, then, each IRQ, see if that counter is > 1000000000 (ns). when it is, call your 1Hz handler and subtract 1000000000 from that accumulator. on average it will be within +/- 1ns
08:55:09 <t3hn3rd> Oh wow! That does seem like a really decent solution, will have a play later on!
08:55:35 <t3hn3rd> lkurusa: Finally - despite wireshark not capturing ICMP responses for some odd reason.
08:55:47 * Vercas is going to have a lot of fun with plain Ethernet.
08:58:09 <t3hn3rd> But yeah, I'm aware how odd the idea of having the UI/WM as part of the kernel is, but the OS/Userland is going to run on a VM platform (byte-code/non-native language), so having the Window Manager as part of the Kernel should speed a lot of things up.
08:59:22 <lkurusa> it’s not odd - you make your OS the way you want it to be
08:59:35 <lkurusa> besides, I think Windows also has the WM in the kernel (or rather close to it)
09:00:45 <t3hn3rd> That's the point, right? I deliberated over 'best practices' for a huge amount of time, before realising that it's a hobby project for fun/learning/exploration, why should I follow a perceived norm.

09:05:55 <Vercas> lkurusa: That's quite the opposite.
09:06:22 <Vercas> The `wm` in `dwm.exe` (which you can find in your process list) should point you in the right direction.
09:07:20 <Vercas> Before Windows Vista, it indeed used to be partially in the kernel.
09:07:34 <Vercas> And pre-Vista Windows didn't even support compositing!
