@k900:0upti.meK900It should support it21:20:45
@luke:vuksta.comLukeOr I guess halfway there? 21:20:46
@k900:0upti.meK900DSC is baseline for DP 1.421:20:49
@k900:0upti.meK900Generally21:20:52
@elvishjerricco:matrix.orgElvishJerriccoisn't there a DP 1.4a or something that very slightly upgraded DSC?21:21:18
@luke:vuksta.comLukeRadeon VII does not seem to support DSC21:21:51
@k900:0upti.meK900Vega has 1.4a21:22:14
@luke:vuksta.comLukeOh wait maybe it does21:22:16
@luke:vuksta.comLukelol21:22:18
@luke:vuksta.comLukeLooking at the wrong specs21:22:23
@k900:0upti.meK900It definitely should21:22:40
@elvishjerricco:matrix.orgElvishJerricco(btw, is there a way to tell from linux whether DSC is in use? I've never been able to figure that out)21:22:41
@k900:0upti.meK900It is a very very slightly upgraded Vega21:22:53
@luke:vuksta.comLukeBasically a compute card with outputs strapped to it lol21:24:13
@k900:0upti.meK900Eh, Vega was a perfectly capable gaming GPU as well21:26:15
@k900:0upti.meK900It was honestly way overspecced for rendering given the super wide backend21:27:55
@k900:0upti.meK900(and that's why they went with wave32 on RDNA)21:28:09
@luke:vuksta.comLukeI originally picked it up for compute purposes actually - it was a great deal with awful software support for 16GiB of VRAM when it came out21:30:10
@luke:vuksta.comLukeStill quite capable on ROCm actually 21:30:27
@luke:vuksta.comLukeI'm quite fond of it - I can't find info about DSC support though21:30:54
@k900:0upti.meK900Again, DSC is baseline for DP 1.421:31:35
@k900:0upti.meK900And Vega should have 1.4a21:31:42
@elvishjerricco:matrix.orgElvishJerricco (I guess, at least for amdgpu, /sys/kernel/debug/dri/0000:03:00.0/DP-1/dsc_clock_en indicates whether it's in use?) 21:33:35
@luke:vuksta.comLukehttps://web.archive.org/web/20210619070751/https://community.amd.com/t5/graphics/radeon-vii-lg-27gn950b/td-p/46063921:40:45
@luke:vuksta.comLukeSeems not21:40:53
@luke:vuksta.comLukeI wonder if HDMI can handle it? 21:41:40
@k900:0upti.meK900Definitely not without DSC21:41:47
@k900:0upti.meK900Probably not at all tbh21:41:50
@k900:0upti.meK900But that is VERY STRANGE21:41:57
@k900:0upti.meK900The hardware should definitely be able to do it21:42:02
