<x8dcc> I was literally going outside and then I remembered something. About the debug exception issue I was talking about yesterday, Since IRETD restores EFLAGS, couldn't I just unset the trap flag bit when I enter the ISR and then IRETD would restore the old ones?
<x8dcc> that way I think it would not debug itself
<x8dcc> I still need to leave so I will check it later

<ChavGPT> i watched a video about cats and comments say it is lying
<ChavGPT> video claims cats check up on you in the morning
<ChavGPT> and it is totally not about food
* ChavGPT throws gogs a snack
<ChavGPT> what is your take gogs
<gog> they're checking to see if you're dead because if you are then you're the food
* ChavGPT is happy to not own a gogs
<gog> speaking of cats i pet an orange kitty on the way to work this morning
<gog> v friendly 13/10 would pet again
<ChavGPT> maybe cultures eating cats have it right

<mcrod> rest assured that much weirder things go on with the internet
<jimbzy> Interesting... My laptop shutdown during the middle of the night.
<mcrod> that was me, sorry.
<jimbzy> Ahhh. I see the problem. I forgot to plug it in. XD

<mcrod> god I hate audio
<gog> h*ld h*nds o//o
<ChavGPT> rust assured
<ChavGPT> so i just watched another cat video
<ChavGPT> one of videos earlier today: why can't sleep with you
<ChavGPT> ez -- they protect you bro
<gog> protecc
<ChavGPT> now the one i got: they feel safe bro
<ChavGPT> basically pick whatever narrative makes you feel better and roll with it
<gog> basically
<gog> there's a myth that cats don't meow to communicate with one another
<gog> but i've seen videos of a cat with a collar cam and they meow at one another all the time
<gog> it's certainly not as much but it does happen
<mcrod> today my cat knocked over a glass bulb.
<ChavGPT> i'm waiting for someone offended at the idea their cat it like other cats
<ChavGPT> s/at/by/
<zid> my cat goes up to other cats and says in a very deep voice "Oi, fucker"
<mcrod> yay I fixed it

<Hammdist> if I update the memory contents of page tables, is `tlbi vmalle1is ; dsb sy ; isb` sufficient to make the new mapping effective?
<Hammdist> linux uses a different sequence https://elixir.bootlin.com/linux/latest/source/arch/arm64/include/asm/tlbflush.h#L238 but plugging that in does not fix my current issue

<geist> interesting writeup on a new sifive core announced: https://chipsandcheese.com/2023/09/03/hot-chips-2023-sifives-p870-takes-risc-v-further/
<bslsk05> ​chipsandcheese.com: Hot Chips 2023: SiFive’s P870 Takes RISC-V Further – Chips and Cheese
<geist> looks like they're getting pretty aggressive now
<nikolar> could be interesting
<nikolar> but they are directly competing with arm so who knows
<geist> yeah that core lookssl ike a direct competitor to a high end arm core
<heat> oh fun tidbit i saw today
<heat> intel is coming up with family 16h
<heat> i don't know what for though
<nikolar> family 16h?
<heat> yeah, cpuid family
<nikolar> ah right
<zid> i7dx
<geist> huh they've been stuck on their previous family forever
<Ermine> heat: how are you?
<geist> i guess that doesn't really collide with AMD's family 16h since it's a different vendor
<zid> maybe we finally get fred
<geist> i think what, intels been using family 0xf forever?
<nikolar> wonder why they feel the need to that right now
<geist> possible theyre switching families because they literaly ran out of space. iirc there's been this one 8 bit space they've been filling in
<heat> Add New Intel Processor family for SMBIOS Type 4
<heat> Hex value - 16h
<heat> Name - Intel® Processor
<heat> in tianocore
<geist> and iirc it's getting fairly full
<nikolar> interesting
<geist> also i forget, itanium used up a family id i think
<geist> the way intel maps cpu implementations to family is a complicated mess. AMD is much more straightforward
<heat> huh now im wondering if this is just some smbios crap
<heat> it says processor family which I assumed matched up with CPUID
<geist> i'll ask around at work, thjough may not be able to say anything based on what the answer is
<bslsk05> ​github.com: edk2/MdePkg/Include/IndustryStandard/SmBios.h at master · tianocore/edk2 · GitHub
<geist> ah yeah thats just some enum
<geist> and for whatever reason 16h wasn't used before
<gog> fjölskyldutala
<zid> lga4710-2 inc though
<sham1> gog: bless you
<zid> so they can glue more bad i7s together to sell
<geist> but for similar reasons it looks like, that enum is running out of space assuming it's fixed to 8 bits
<geist> so probably going back and filling in the gaps
<geist> i got a new external backup drive, now i begin the slow process of filling it with random garbage before formatting it with dmcrypt
<geist> going to take....16 hours

<ornx> does something special in x86-64 go at address 0xf? is that real memory? my EFI memory map i get after exiting boot services says there's a block of memory there 12288 bytes long...
<ornx> 3x4096... 12x1024...
<heat> ornx: no
<heat> i'm willing to bet you're reading the memory map wrong
<heat> 0xf sounds very bogus
<heat> pls show code and struct definition
<zid> yea you're either offset by some amount, or you overread, or you read the flags as the address, presumably
MiningMarsh has joined #osdev
<heat> EFI has a fun detail where the map descriptor's size is an out-parameter of GetMemoryMap
<heat> you *CANNOT* do EFI_MEMORY_DESCRIPTOR *desc = ...; for (;; desc++)
<heat> rather for (u8 *ptr = descriptors; /* some condition i cant remember */; ptr += desc_size)
<zid> The multiboot one is described using that weird negative format too
<zid> why's it gotta be so weird in general
<heat> so it's extensible
<ornx> src/amd64/entry.c:689 assertion failed: desc_size == sizeof(EFI_MEMORY_DESCRIPTOR)
<zid> negative indexing does not make something sextensible
<heat> tianocore actually has a funny gotcha there where they increment the descriptor size
<heat> ornx: ^^
<heat> it will not match sizeof(EFI_MEMORY_DESCRIPTOR)
<heat> on purpose
<ornx> ahh
<heat> the clever cunts added a gotcha so everyone used desc_size
<ornx> wait, how do you index the fields inside of it then
<heat> bruv
<heat> for (u8 *ptr = descriptors; /* some condition i cant remember */; ptr += desc_size) {
<heat> EFI_MEMORY_DESCRIPTOR *desc = (void *) ptr; }
<heat> i have no idea if my shit irc client made the void pointer into a smiley
<heat> but if it did, it's pretty funny
<zid> It did not
<heat> aw
<ornx> ah so you can use the struct offsets, just not the struct sizeof
<bslsk05> ​i.imgur.com <no title>
<ornx> that's fine then
<heat> yes
<heat> ofc blah blah be careful and don't access beyond the actual size
<zid> I'd delete that irc client immediately
<heat> but i don't think the memory map descriptor has been expanded, ever. might be wrong though
<heat> zid: i'm on web.libera.chat since i'm on windows and i don't do nerd programming on windoze
<zid> yea, delete web.libera.chat
<zid> or install wsl and irssi, or mirc
<heat> i don't want to have a full linukz running for irssi
<heat> an idle WSL2 system with bash open balloons like half a gig or something, last i checked
<zid> yea mine's using 645MB, but, so what?
<zid> That's 1/64th of my ram
<zid> and windows *loves* swap, so I can probably run a hundred of them np
<heat> yeah but i have 8 gigs
<zid> why
<zid> did the other 24 fall out
<heat> its a shitty laptop from 2018
<zid> Did the other 8 fall out then
<heat> it was (back then) 800-ish euro
<heat> aka not a high end thing
<heat> even had a mechanical drive lol
<zid> good thing about laptops is that you can buy ones with mech drives and crap ram
<heat> i'm not upgrading while CS2 doesn't force my hand
<zid> and then replace the drive and the ram
<zid> for cheeap
<ornx> huzzah, now everything works and the numbers make sense
<zid> 1 slot or 2?
