<javierm>
ups, I just noticed that yesterday made a question here that was meant for the fedora-kernel channel...
<javierm>
geertu: hi, I saw that you added support for Okaya RH128128T in drivers/gpu/drm/tiny/st7735r.c. Module autoloading is not working for that variant
<javierm>
geertu: it's again the issue we talked in the past that module alias are reported as spi:<device>, I'll post a patch for you in a minute
NonaSuomy has quit [Ping timeout: 240 seconds]
<geertu>
javierm: Possible, usually I don't autoload modules
<javierm>
geertu: yeah, in Fedora we build everything as a module since is a general purpose OS
<javierm>
geertu: btw, bought a rpi4 lcd display hat that has this chip. Pretty neat
<javierm>
I'm building a portable handheld for my kids using a rpi zero 2w :)
<hanetzer>
javierm: as in, like an emulation gameboy?
* hanetzer
would like to get ahold one of one of those 'rootable' switches for that purpose
<javierm>
hanetzer: yes, they already have one with a rpi4 and retropie, so the idea is to do the same but making it portable
<hanetzer>
vaguely interested in that myself. I wish there were mechanical switches small enough for gamepads :P
<javierm>
hanetzer: the lcd display hat has! that's why I'm using it :)
<hanetzer>
heh. I saw this one dude, he took a gameboy advance carrying case (which looks like a jumbo sized gba), cut down an n64 pcb, and made it into a portable n64
<javierm>
hanetzer: haha
<hanetzer>
javierm: but yeah. I had thought to make something like that. was considering putting an rp2040 on the board and having it be usable as a plain usb gamepad as well :P
<javierm>
hanetzer :)
<hanetzer>
javierm: another fun option I was thinking of was a mech board, but like with a pretty big body, with a pi zero in it you could just hook up to a monitor
<javierm>
hanetzer: I actually bought an old olivetti typewriter in an antique store and my plan is to retrofit it to be a USB keyboard
<hanetzer>
heh
<javierm>
my kids also found that a fun experiment to do

arnd: since 1c4b5ecb7ea190fa3e9f9d6891e6c90b60e04f24 ./scripts/dtc/include-prefixes/h8300 is a dangling symlink
<ukleinek>
arnd: that's a (soft) conflict with olofj's d5d332d3f7e8 ("devicetree: Move include prefixes from arch to separate directory")
<geertu>
ukleinek: Really? The latter is from 2017
<javierm>
geertu: fixing the SPI modalias issue is not easy. I mean, the change to properly report OF modalias uevent is trivial but a lot of drivers and DTS need to be fixed first
<javierm>
geertu: someone tried to fix how is reported by commit ("3ce6c9e2617e spi: add of_device_uevent_modalias support") but that broke a lot of drivers and DTB relying on the current behaviour so got reverted
<geertu>
javierm: I know.
<geertu>
javierm: But in the long run, this should be fixed for-good.
<geertu>
I deliberately didn't add an entry to st7735r_id[], as all new users are expected to use DT.
sszy has quit [Ping timeout: 244 seconds]
<geertu>
In theory, you can use the device without DT. But there are devices that need more DT infrastructure around it, which cannot be provided by instantiating a classic spi_device in board code.
<geertu>
Hence it seems silly if you have to add the device to the spi_device_id anyway.
<geertu>
spi_device_id array
<javierm>
geertu: absolutely agree. In fact, I also added to the ssd130x-spi driver only for module autoloading but didn't set the struct spi_driver .id_table to it
<javierm>
geertu: every once in a while the kernel test robot complains about it, but I won't fix that
<javierm>
because setting it just to fix the compile warn would actually be the wrong thing to do

<hanetzer>
do spi devices tend to have any form of id code in them?
<hanetzer>
(as in not-flash; I know spi nand/nor have jedec ids)
<broonie>
The protocol used with an individual device is completely up to the device. Many devices have ID registers or commands but you need to know what you're talking to to know how to query identity information.
Pali has quit [Remote host closed the connection]
<jn>
hanetzer: in the general case, no
<jn>
as broonie said more eloquently
<hanetzer>
gotcha. so nand/nor flash just follow *a* standard, and that's why it wworks, but other spi devices could follow others or implement their own.
<jn>
yep
<geertu>
hanetzer: Exactly. The simplest SPI devices are the venerable 74HC595/74HC597 shift registers, converting serial to/from/ parallel data.

venerable is such a good word. if memory serves I learned it from D&D lmao

<gpiccoli>
o/ ardb - sorry for the ping! Can we use NULL_GUID for a new EFI variable, or should create a new GUID? Is there a process for creating a guid? Thanks in advance!
<ardb>
gpiccoli: you can use any GUID you want except NULL_GUID
<gpiccoli>
LOL
<gpiccoli>
ok, it's a good start for me heheh
<ardb>
they are essentially namespace identifiers
<gpiccoli>
I'm sharing the CRASH guid with efi-pstore, but I'm not sure it's a good idea
<ardb>
so just generate a fresh one (using uuidgen)
<ardb>
and put all related stuff under it
<gpiccoli>
cool ardb , I'll do that! Thanks
