Necessary firmware for Navi14

<< < (2/6) > >>

MPC7500:
And one more thing. When you blacklist the AST GPU on boot, then you don't need a xorg config file at all.
You only need the config file when you're using the AST GPU (for high resolution) or if you don't blacklist the amdgpu or AST GPU.

BUT on Void you have to blacklist the other GPU otherwise it won't work. Anyway it's the better solution to blacklist one of the GPUs.

r34per:
Is the general consensus that navi14 firmware is too big for the bootkernfw? I've tried omitting various files to try getting the size down to no avail. With how my monitors are set up I can pretty much only use the HDMI port on my rx5300 or the onboard hdmi port of the blackbird, and it's a bit of a pain having to constantly climb under my desk to switch the ports when I need to use the boot menu. I just leave the onboard vga disabled just use the serial console on openbmc from my laptop when I need to get into the menu now, but of course being able to just use my rx5300 would be most ideal because I switch between void linux and fedora rather often.

MPC7500:
I have a HDMI Switch.

so i can just blacklist the ast in the bootloader and not have to flash firmware to use a pcie gpu when the OS boots?

MPC7500:
You only have to flash the firmware when you want the GPU also in Petitboot.
You could instead use the AST til Petitboot and then switch to the AMD GPU (and blacklist the AST).
