dmesg output cutoff after the proposed patch applied
I guess the comment is correct as, in the other part of the patch, the device is recognized with the CHIP_RAVEN flag; in another hand, as I also set the AMD_IS_MOBILITY flag, /* Raven Mobile */ might be a better comment... with regards J. Mayer This is in kernels >= 5.4. Do you need this in earlier kernels? |
Created attachment 591776 [details] emerge --info output AMDGPU stock driver does not recognize new Picasso implementation as found inside the AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx APU. The hardware seems to be the same as Raven one with mobility capability added. Thus, it's easy to make it recognized, adding the new PCI ID to the AMDGPU driver. Here you'll find the patch I've made to my kernel; graphics is OK, with no noticeable issue.
