ChanServ changed the topic of #aarch64-laptops to: Linux support for AArch64 Laptops (Asus NovaGo TP370QL - HP Envy x2 - Lenovo Mixx 630 - Lenovo Yoga C630)
<shawnguo>
steev: there seems to be some nasty timing issue which makes hardware be accessed without clock in some case.
<shawnguo>
the issue is not 100% reproducible, and when I was reporting the issue to LT engineer, she has problem to reproduce it on her sdm845 development kit.
<shawnguo>
are you actually able to see the issue on your c630?
<steev>
the kernel panic when the tests are run?
<steev>
i am when i enable CRYPTO_DEV_QCE and CRYPTO_MANAGER_DISABLE_TESTS is not set
<steev>
actually, i think i might have run into it even with manager disable tests set

<macc24>
:D i got a mips laptop
<macc24>
the sacred 3rd option
<steev>
i always wanted a longsoon, but could never find one
<macc24>
i got it from a friend, who got it from a friend who bought it for openbsd development
<macc24>
i can probably restore it to its older glory...
<macc24>
former*
<gwolf>
MIPS? Wow, I haven't seen those in ages
<mattst88>
macc24: which laptop did you get? a yeeloong or one of the newer Loongson 3s?
<steev>
shawnguo: okay looking, on working (5.12), i have CONFIG_CRYPTO_DEV_QCE=m, CONFIG_CRYPTO_MANAGER_DISABLE_TESTS=y; disabling CRYPTO_MANAGER_DISABLE_TESTS causes the kernel panic.
<macc24>
i'll talk to an openbsd dev about it as he knows around them...
<macc24>
steev: my 10 seconds of experience with low level qcom stuff tells me it's related to power domains
<steev>
macc24: just giving shawn the info so he can pass it on to the LT engineer :)
<macc24>
mattst88: also i heard the unit i got is broken :| will need to fix it
<macc24>
i hope i can fix it
<macc24>
i /wish/ i had newer mips laptops
<macc24>
wait the yeeloong got an 800mhz cpu wtf
<macc24>
i heard of microcontrollers that have faster clock
<steev>
hey, it's still usable for.... editing files in emacs
<macc24>
i'm kinda torn on whether i should fit it with new internals that i have laying around and use it because it's a cute laptop - or restore to completely maxed out stock settings
<macc24>
if i end up putting new internals into it i'd like to slowly replace its case with a 3d printed one that would be compatible with stock parts
<macc24>
i have a thing for laptops that are literally 2 boxes and a hinge ,_,
<macc24>
i'd also like to reinforce it a bit if i replace chassis, likely by embedding metal parts into 3d prints
<mattst88>
macc24: the laptop is very small, and there's really only one upgrade you can do to it: install a 2.5" SSD
<mattst88>
the RAM is not upgradable past 1GB
<macc24>
mattst88: i meant literally replacing the motherboard with something else(c201pa board i have laying around)
<mattst88>
ahh
<mattst88>
macc24: you'd probably want to replace the screen too, since it's 1024x600 :(
<mattst88>
2009 netbooks. how did we ever think they were a good idea?
<macc24>
mattst88: 1024x600 is good for gpu performance
<mattst88>
heh
<macc24>
when the graphics card is "llvmpipe" every pixel matters
<mattst88>
the siliconmotion GPU in the yeeloong has only 4MB of RAM, and by default X allocates a square framebuffer, so 1024x1024 for a 1024x600 screen
<mattst88>
and the funny thing is... 1024x1024x32bpp == 4MB exactly
<mattst88>
so X will fail to start because it cannot allocate memory for a hardware cursor :P
<macc24>
that thing can do opengl?
<mattst88>
no, it's 2D only
<macc24>
ah
<macc24>
so it's a glorified crtc
<robclark>
once upon a time, 2d accels were a thing
<macc24>
uh like planes and stuff?
<robclark>
more like bitblt
<macc24>
i'll be back in a week or two
<macc24>
bye~
