Hello.
I’ve compiled the radeon_hd driver from latest source.
I’ve unset the if 0 to add my 6700xt to be recognized.
In connector_probe (accelerants/radeon_hd) after Path 4 (see below), it failed (Segment violation).
Before digging into the driver code, is it a know issue with this driver, or it’s just not complete yet … if it’s the case, where did I have to look to fix this bug and be able to load the driver ?
Thanks.
With the log it’s better

Probably ticket #17377
Hi there, thes “#if 0” were there on purpose because the driver did not work correctly for some cards and or cards and hardware combinations, so in that sense it is known indeed. But the specific issues may not be written down. So you will indeed need to do some debugging.
If I remember correctly, we tried adding some new cards to the driver without adjusting anycode, it didn’t work, so we kept them disabled until someone has time to investigate the problem.
You will have to find what changed for these newer cards and why the driver doesn’t handle them correctly.
FYI I tried Haiku on MiniPc with 8745HS/780M, and it’s not Radeon driver loaded. Maximum resolution is FHD.
Yes it’s the one. Thanks.
I will investigate to see if I can fix it.
It’s what I’ve expected, but if you don’t try, you don’t know
I’ve already investigated the Linux driver, we will see next WE if I can fix it
