<bbrezillon> macc24: I didn't manage to replay your trace, but this MR might fix the problem https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/7821

<robmur01> br: SMMU does at least use the formats defined for the CPU ;)
<robmur01> for the MIdgard format, the page type bit is different, the access flag is inverted, some of the permission bits are inconsistent, the control registers and TLB maintenance paradigm are wildly different, and the relationship between VA size and table depth is busted
orkid has joined #panfrost
<robmur01> it's really only the fundamental table structure that's common to LPAE, so the amount of code that can be shared without descending into a huge mess is really only the basic table walking stuff
<robmur01> it's not that is dislike io-pgtable (code reuse is always good!), just that in hindsight, if I was starting again I'd be inclined to reduce the level of abstraction, in the hope that all the driver-specific behaviours could stay in their respective drivers

rando25892 has quit [Read error: Connection reset by peer]
rando25892 has joined #panfrost
<macc24> bbrezillon: now it segfaults a bit later
<macc24> without glitching out
<bbrezillon> same backtrace?
<macc24> oh let me check
camus has joined #panfrost
<macc24> it looks quite similar to me
kaspter has quit [Ping timeout: 256 seconds]
camus is now known as kaspter
<macc24> huh
<macc24> i recompiled it to debug-optimized build and it has different backtrace
<macc24> bbrezillon: https://bpa.st/X7KA
<bbrezillon> ouch
<bbrezillon> macc24: can you try the version I just pushed?
<macc24> yes
<macc24> bbrezillon: yep it works fine now

* alyssa writing a compiler in Python because she's annoying like that /s
<HdkR> Annoying? Nah
davidlt has quit [Ping timeout: 240 seconds]
<alyssa> ok, have instruction packing setup for IR'
<alyssa> So now basically pending on actually reworking the compiler to use the new facilities
<alyssa> which I.. really don't have time for until classes finish up next week
<alyssa> Boo :p
<anarsoul> winter break is coming
<anarsoul> you'll have lots of time to work on panfrost :)

<alyssa> anarsoul: (:
<macc24> anarsoul: >not doing dev work at school
<alyssa> macc24: what is this 'at' school you speak of
<macc24> alyssa: my desk since school moved to ms teams(yuck)
<macc24> after the pandemic commute to school has decreased from 1h to around 10s
raster has joined #panfrost
<alyssa> ms teams manages to break not only on Linux web browsers but also ChromeOS browsers and Android browsers
<alyssa> at least Zoom works in Chrome on Linux most of the time
<HdkR> Delete MS Teams and Zoom :)
<macc24> yeah it's bad
<macc24> i installed chromeos on my c100pa for this specific purpose ,_,
<HdkR> I didn't realize video conference applications could be so bad until I saw Zoom footage
<anarsoul> alyssa: I have occasional meetings in ms teams and it works fine in browser for me
<daniels> Teams calls have always worked perfectly well for me in Chrome, provided you can log in
raster has quit [Remote host closed the connection]
<anarsoul> google meet works better though
raster has joined #panfrost
<alyssa> Maybe it just hates my computers then :c
<alyssa> Teams android has been my workaround and that -does- work but oy
<alyssa> Google Meet is the only one of the bunch that has worked reliably for me
