Regarding relatively cheap ARM laptop there is TCL BOOK 14 Go B220G 8GB/256GB but it seems that hardware support for Linux is rather poor and even Windows can't be easily reinstalled if you don't know how to integrate drivers into installation image
<Stalevar>
But I think $300 is still too much for a laptop for masochism practices

linusw__: you picked the wrong side, but of course I'm not angry anyhow :-)
<ukleinek>
linusw__: Thanks for your third opinion.
<linusw__>
ukleinek: thanks, you and Andy alike are some of my favourite coworkers after all.
<javierm>
ukleinek, linusw__: FWIW I agree with Andy on this one, having it explicitly makes it easier to know what are the consumers of the exported macro on the given namespace
<javierm>
making it implicit due a header include kind of disminish the point of using the namespaced symbol import
<geertu>
linusw__: Ah, the first thing that came to my mind when reading ukleinek request here on IRC was to defer the decision to the other Linus ;-)

I'm too dull to even understand the importance of namespacing :/
<mvaittin>
I was with you on this one UK :)
<mvaittin>
point of namespacing (to me) is to reduce the visibility. When headers contain only stuff which is relevant to a specific namespace - then automatic import just makes things simpler while the visibility is still limited :)
<mvaittin>
But luckily there are people with bigger brains ;)

<ajb-linaro>
where are the arm,armv8-timer\0arm,armv7-timer FDT nodes documented? I've been adding the SEL2 physical and virtual timers to QEMU and want to know if the kernel even cares about seeing them advertised in the FDT?
* ajb-linaro
has a thought - why does the kernel even care about SEL2 timers.... I guess this is the DT the firmware sees and maybe passes to the SEL2 hypervisor

<mrutland>
The kernel won't care about the secure side

ajb-linaro: the DT is not non-secure specific. it is supposed to describe the platform.
<ajb-linaro>
maz: sure - so the canonical Arm platform DT spec is in the kernel or somewhere else? My test case (Hafnium) doesn't seem to care because it boots once the timers work
<maz>
ajb-linaro: I don't think that there is a canonical DT spec. there is a bunch of arbitrary choices, the DT hosted in the kernel tree being one.
<mvaittin>
ukleinek: I just trust the people who make these decisions have bigger brains than I do ;)

<ajb-linaro>
is interrupt-controller a DT node or a property of something else?
<maz>
a property. it denotes that the node containing it is what it says on the tin.

headless has joined #armlinux
<ajb-linaro>
I guess hafnium should probably be looking for something else then -> fdt_find_node(fdt, "/interrupt-controller", &n) makes no sense
System_Error has joined #armlinux
<maz>
ideally, you would look for the interrupt-parent of a given device.
<maz>
there is no such thing as an "absolute" interrupt controller, it is always relative to a device.
