Re: How to determine if graphics is supported by radeondrm?
as previously mentioned, the "radeon" DRM/KMS driver supports only older AMD GPUs - mostly everything of the TeraScale family. we do not yet have a working port of the "amdgpu" driver for newer stuff in 9.x or -current. until last year, I was happily using a Radeon HD 6570. this is a GPU introduced in 2011 with TeraScale 2 and DisplayPort, available in low-profile forms. I had trouble finding open source software that would not run at 1080p. several NetBSD developers like the Radeon HD 5450 because it is fanless. > Am I better off looking at iNtel stuff? if you want a newer integrated GPU, yes, in 9.x we support everything up to (including) Kaby Lake, which is hardware that debuted in 2016 and was discontinued for desktop processors in 2020. if you want a better CPU and are happy with an older external GPU, i would not advise getting Intel stuff. newer x86 hardware supports a generic unaccelerated full resolutoin dumb UEFI framebuffer. llvmpipe (the software OpenGL driver) will be chosen when this is in use. llvmpipe is very good on CPUs with lots of cores and threads, it is highly paralell. hope this helps, nia

I looked up that model and it seems to have a "Intel Core i7-7700HQ" CPU in it, which (because of the 7xxx number) is apparenly of the 7th generation, which is apparently the latest that NetBSD has support for. > None of the trackpads on my laptops worked with the NetBSD image I was using > and I did not look into why.

re: How to determine if graphics is supported by radeondrm?
radeondrm does not support any modern graphics card, and we don't have a working amdgpu driver yet (last i tried, it hung at boot and i did not have a serial console setup to test with yet.) you can have almost OK stuff with the vesa driver. maybe wsfb also can work. we're working (slower than hoped) on a drm update, but we do not have any ETA currently. .mrg.

Thanks for doing the experiment. I guess it tells us what I already
feared, that it doesn't do accelleration.
I think that the long list of AMD GPU models is simply always printed by
the AMD driver ("Look at all the models I support!") and then later it
decides if it really supports the GPU that's there. For instance on my
current box, it reports at some point after the long list:
[34.593] (--) RADEON(0): Chipset: "ATI Radeon HD 5450" (ChipID = 0x68f9)
(or maybe that's only because I have told X to use the Radeon driver and
not the modesetting driver...)
