Trying to install gentoo to a vm in ESXi 6.5 and passthrough a radeon HD 6350
Originally I got the "Unable to locate a BIOS ROM" error, but I applied the patch https://lists.freedesktop.org/archives/dri-devel/2014-November/072701.html and now the gpu is recognized fine.
Then when I ran startx with no config (after following the install steps in the wiki), xorg complains about missing drivers for the VMware virtual GPU.
So I put a file in x11/conf.d to choose the right device and driver, but now xorg messages "No Devices Detected".
I tried "X -configure", but it segfaults when it tries to use the pci device 27@0:0:0

dmesg
20-radeon.conf
Xorg.0.log with 20-radeon.conf
X -configure output and Xorg log
lspci
lspci -vvv entry for the radeon card
kernel config

I don't know that the Command buffer error in dmesg is about - it doesn't show up again if I run startx again

Maybe I don't understand but either do pass the video card and use drivers for them or use the virtual gpu and use vmxgfx?
Or do you want both at the same time?

I don't want to use the vmware GPU - just the passed-through one with radeon.
I tried disabling the vmware GPU but them the VM doesn't start.
