Yea all this techbro market disruption has been a real fucking coup

they basically just deregulated a bunch of successful industries

mjg, openbsd fixen really?
<heat>
i've quit openbsd like twice
<heat>
you've*
<mjg>
well they claim it's a hardp roblem
<mjg>
a little nudge wont hurt
<mjg>
it's not like i'm writing the entire thing for them
<heat>
oh is that what it takes?
<heat>
dude how about that vm locking in onyx huh, really hard problem
<mjg>
bro
<mjg>
you are as easy as your mother
<mjg>
wait am i going too far
<heat>
:(
<mjg>
do you have working inode reclamation yet
<mjg>
does it survive at the 8 or whatever scale on your desktop
mavhq has joined #osdev
<heat>
no i've been working on swap lately
<heat>
and extra lately just linux innit
<mjg>
i think the other l man may like you
<heat>
the 3 letter l man?
<heat>
or the 5 letter l man?
<mjg>
i would not specify 'the other' if it was *the* L man
<heat>
there's also 4 letter l man
<mjg>
i thought he goes by a j nick
<heat>
i'm objectively likeable mon
<heat>
until you hear my hot takes
<mjg>
that's the thing man
<mjg>
i heard them, he did not
<heat>
my hot takes are also aggressively pro-linux sooo
<mjg>
hm
<mjg>
yo mofer
<heat>
there was nice quote by someone(tm) yesterday: "but I notice that every time someone brings up BSD anything, it's a no from you"
<mjg>
i'm confident there is more ez wins on the table
<mjg>
than the batching on exit
<heat>
oh i've seen that problem before in onyx: the answer is 'no' unless you can take an inconsistent interval tree from the page cache's side
<mjg>
you would do shit speculatively
<mjg>
maybe aid yourself with seqc
<heat>
seqc? how freebsd of you
<mjg>
i would talk about this on #mm but the local l man may accuse me of nto ranting about bs
<heat>
if you want Huge Wins try and come up with an interval tree that isn't a rb tree :)
<mjg>
that's not where wins are waiting
<mjg>
in a multicore setup
<heat>
sure they are
<mjg>
no
<mjg>
even if you made them literally 0 cost
<mjg>
the real problem is the lock acquires
<heat>
maple could do it really well if it supported stacked entries at all
<heat>
and with maple, rcu
<mjg>
you are not going to get away from taking the lock several times per exec
<mjg>
which is the primary problem
<mjg>
the thing to do is to distribute the state
<mjg>
for example instead of linking in all mappings, you link in mm_structs which use the inode
<mjg>
and maintain per-mm trees
<mjg>
this means the traversal is more expensive of course, but it also means modifications are *way* cheaper
<mjg>
right now for most fucked inodes you get 5 lock/unlock trips for execve + mmaps + 1 on exit
<mjg>
with the state distributed you are down to 1 for execve and on 1 exit
<mjg>
note that osmething like the dynamic loader has the same pages continuously mapped and umapped
<mjg>
i mean, can you agree only taking the lock twice per exec + exit trip is going to scale better than taking it six times
<mjg>
even if the latter has shorter holds
<mjg>
i'm gonna hack it up when i get to it
<mjg>
right now i'm deep into vfs perf breakage :d
goliath has quit [Quit: SIGSEGV]
<heat>
i'll guess that traversing mm's on reclaim is problematic and not really a good solution
<heat>
they whacked that like 18 years ago for swap
Turn_Left has joined #osdev
<mjg>
it is something to ponder, the key is this is never going to perform unless the state is somehow distributed
<heat>
OR rcu
<mjg>
does not have to be per mm specifrically. for example you may notice the indoe is contended to fuck, so you alloc an array of 4 tress and you hash cpus into it
<mjg>
it does need to store some of the state mon
<mjg>
and the point is to not globally bounce lines every time this happens

geist trying to medal in the nap olympics
<geist>
nah finally got back onto a new proper sleep schedule post trip, took about a week to reset my brain
<geist>
midnight - 8am. it wont stick forever, but it’s a good schedule
<nikolar>
nice
<zid>
Thrown away his medal hopes, sadge :(
<zid>
I believed in you
<geist>
well, i also have thispinched nerve in my neck, so that tends to limit sleep
<geist>
since at some point i have to give up and top off the NSAIDs
<zid>
ah, injury during training, rip
<geist>
folks, take care of your posture, it’ll come to rear its head when youget older
<zid>
I slept on my ear funny if that helps
<mjg>
dude i wake up at 7 am
<mjg>
somehow
<mjg>
i have no idea how long that's going to last
<mjg>
the thing is i did not even try
<geist>
yeah i’m not so much a late riser as much as i tend to go to sleep later and later
<geist>
all it really takes is one late night hacking session or some late night gaming session
<mjg>
that is a rather common nerd problem
<geist>
and then the sleep schedule gets pushed out
<geist>
indeed.
<mjg>
in my youth i would cycle
<mjg>
i loved when i slept 9-5
<mjg>
:d
<zid>
Natural rhymthtn for most people is 25-26 hours
<zid>
if you don't make them sleep with an alarm, they settle into that
<zid>
unless it's pitch black, then they get all sorts of confused and stay up for like 40 hours just thinking it was super boring and taking forever for each day to pass :D
<heat>
sleeping 9 to 5???

I like how there's a "correct"
<mcrod>
sham1: sorry, you are now ham1 in my mind
<sham1>
Surely not, it's an identifier not a string value

and then shower me with money because it looks like my primary monitor has failed
<mcrod>
i wonder if the new kitten chewed my dp cable
<zid>
Mine is in a perpetual state of failing
<zid>
I sort of wish it'd just give up
<zid>
I get snow if certain patterns are on screen, and it likes to drop bits out of the instruction pointer and jump to random bits of firmware
<zid>
or reboot
<zid>
I got a 1080p backup monitor sorted now so it's allowed to die at this point
<zid>
but I'd rather use this one
<mcrod>
real life friend has an astonishingly beautiful HDR monitor
<mcrod>
but, that's money.
<mcrod>
the HDR on this monitor is absolutely useless, and I refuse to use it
<zid>
6 bit pixel LCD for life?
<mcrod>
sure
<mcrod>
hdr looks nuts on my mac
<zid>
My monitor has really crappy viewing angle so most things don't look as black as they should :/
<mcrod>
however, even if I could just up and get a nice HDR monitor right this second
<zid>
the edges are visibly slightly 'inverted' compared to the middle
<mcrod>
GNOME still doesn't do HDR
<mcrod>
i'm now waiting for heat to tell me i'm wrong
<zid>
if you've seen an LCD from the side you probably know what I mean about the inversion
<mcrod>
yeah I get it
<heat>
i dont know i don't do HDR
<heat>
nor gnome
<heat>
i remember the desktop people had a hackathon like 2 years ago wrt HDR
<heat>
i don't know what came of it
<sham1>
I think GNOME does do HDR if you have the correct colour profiles

yah macs tend to suddenly switch into HDR mode when yuo view something werith it
<geist>
kinda jarring the first time, but it looks neat
<geist>
i forget how HDR is stored in images, but i thin it's basically some additional layer that is applied on top of it
<heat>
mjg, it was a good question innit
<heat>
do you think storing the file interval tree node partially in the write-mostly cache line is a solid idea?
<GeDaMo>
Don't some HDR formats use floating point?
<heat>
big problem is that you don't have a lot of room...
<mjg>
heat: :p
<mjg>
did i mention something about moving it out
<mjg>
lemme think
<zid>
floating point hdr seems like it'd be good
<heat>
lol

your TODO list keeps growing yet you reply to random threads on openbsd tech-kern?

it was part of my todo
<mjg>
also you must not confuse todo in the sense of writing a patch

i don't think anyone's askign you to write a patch here
<heat>
send your ranty email and wait
<mjg>
i am considering doing it concerning the file shit
<heat>
ah ok
<mjg>
hahaha oh man
<mjg>
theo responded

You don't really *need* floating point colour to fix the blacks being crushed though I guess
