We might be able to easily, but will need a copy of /var/log/syslog from Haiku running on the system with the Vega card installed.

Were any of these tested working for you?

[kallisti5]

PCIID's added in hrev52110. Please test and let me know of any cards that don't work at all.

Vega FE accelerant crash at boot works with accelerant disabled in boot menu on x370 Mobo + ryzen 1700x

I have mobile Vega 8 also but it doesn't boot with 4gb limit enabled so can't test it yet... Probably there is a conflict between disabling the ram and where the vram is allocated?

Thanks, kallisti5 for adding the Vega support to the driver. I did note a missing 'Vega' chip name label entry in the code for radeon_chipset RADEON_VEGA:

headers/private/graphics/radeon_hd/radeon_hd.h
radeon_chip_name

It booted to rocket icon on splash screen and I could go into the Haiku boot menu. Check with Karan, but it got that far for me. (7/17/2019 - went to a compatible gfx card)

I'm not sure I follow did you bypass blacklisting of Vega for this driver or run it with the fallback driver?

Are you sure you booted using the radeon_hd driver IIRC Vega and some Polaris are blacklisted, or enabled but just don't work (Vega FE last I checked)... note I think the driver doesn't really kick in until just before switching to the desktop so the boot screen doesn't really count (some devices this will cause a black or white screen temporarily).

Also just FYI nothing has been done in the driver since I last tested on Vega FE. I suppose it is possible something else got fixed though.

Added Syslog (smlnjoe_Vega11_syslog) for Ryzen 5 2400G APU. Using the built in Vega 11 it looks like the Atom Bios is not found and the driver does not load. Nightly 64 bit hrev 53237

This ticket is useless, no feedback from the requesters. I would close it.
