13:39 <DannyB> I found the debug flags for HPM over SPMI (too lazy to trace it), and it doesn't actually look that bad to make work. It looks at a glance like they do identical things to the ports, just tunneled over SPMI instead of I2C.

13:39 <DannyB> but we'll see

13:40 <sven> sounds reasonable, the old tipd chips are mostly standalone with Apple’s firmware

13:41 <sven> once they are powered up we only care about plug/unplug events, cable orientation and alternate mode changes

14:56 <eiln> status update

14:56 <eiln> hevc works, and I think it'll be done before vp9

16:42 <i509vcb> I guess Vulkan video in agxv will be something for the future... However the rest of the driver still needs to be done

16:56 <DannyB> Still can't quite trace macos on m3. Fixed most of the obvious issues, but it crashes executing msr's from the kernel

17:01 <DannyB> Interesting. Any MSR crashes it.

17:01 <eiln> i509vcb: me? this is the video decoder not gpu

17:01 <DannyB> I wonder if there is some lockdown register

17:03 <i509vcb> Elon: vulkan has some video decode/encode extensions now

17:03 <i509vcb> Err eiln

17:03 <i509vcb> (really gboard)

17:03 <ChaosPrincess> thats quite an insult

17:04 <i509vcb> Keyboard autocorrect has failed me many times before

17:04 <eiln> well we can't use it unless we can convince the vulkan people to support actual video decoders

17:05 <eiln> "everything is a gpu" nvidia fault

17:05 <i509vcb> I assume the issue you are getting at is the video decoder is a seperate hardware unit?

17:08 <i509vcb> I'd assume the driver could just have agx and the video encode/decode hardware both opened and manage whatever API stuff is related to interop

17:08 <ChaosPrincess> gl upstreaming that

17:08 <eiln> that's exactly what I'm not gonna do

17:14 <i509vcb> Is what you want something closer to an extension to Vulkan that allows userspace to know what a device is a "video only" device?

23:12 <krbtgt> huh, the apple video apps got an update that apparently doees load balancing between encoders on SoCs w/ multiple... on 14+ only

23:16 <janneg> wasn't that a m2 max/ultra update at release with 13.x?

23:20 <janneg> retrieving the EDID from dcp seems to be surprisingly simple

23:29 <nicolas17> krbtgt: do you mean Final Cut Pro etc?

23:30 <nicolas17> yes

23:30 <nicolas17> Compressor 4.7 "Export HEVC and H.264 files faster by simultaneously processing video segments across available media engines (requires macOS Sonoma or later and a Mac with Apple M1 Max, M1 Ultra, M2 Max, M2 Ultra, or M3 Max)."

23:31 <nicolas17> ditto Final Cut Pro 10.7

23:31 <nicolas17> released yesterday
