Whatevergreen: possible -raddvi issue #2317

Closed AlexKusnezov closed 9 months ago

AlexKusnezov commented 1 year ago

I have a SAPPHIRE AMD Radeon RX 570 NITRO+ 8Gb with Connectors DP,DP,HDMI,HDMI,DVI which never had working HDMI and DVI, only dual DP. If a monitor is attached via HDMI or DVI, it will be detected, but the screen stays black. In Screen Sharing it is also present.

Recently I got both HDMI and the DVI working, but only one at a time by setting CFG_FB_LIMIT to 2 This allows having all of the ports working, but only two at a time - this would be my resource/contribution

Looking at Whatevergreen debug, there seems to be -raddvi is applied also to hdmi, which doesn't seem to be correct:

Can you clairify this, also why is HDMI suddenly working when setting a low fb limit?

if I remember correctly, hdmi and dvi are using the same phy, so for the driver they are about the same. Limiting the active amount of framebuffers is likely doing something to activity checks deep inside the driver.
