03:27 <chadmed> colour management flickering is fixed with plasma 6.2 but not the blur effect black rectangles

03:30 <chadmed> argh never mind its not fixed

08:42 <jannau> sven: I'm currently adding support to all other platforms to 20240806-atcphy-rewrite. do you need the "usb4pmgr" mmio reg? it's unused in atc.c as far as I can see and would pose a problem on multi-die systems. The mmio addresses on the 2nd die are shifted via "ranges" but the system uses only pmgr on die 0

08:52 <nickchan> not doing much with linux right now because in 18.1b4 apple broke the jailbreak used for booting again an I need to fix that first

08:52 <nickchan> it seems to be only a small change though

09:28 <sven> jannau: ugh, thats rewuired for thunderbolt

09:28 <sven> *required

09:32 <jannau> do you need full mmio access? dcp has a similar problem but it just needs to pass a pmgr mmio address to the coproc. Solved there via "pmgr_dcp" and "apple,bw-scratch"

09:45 <nickchan> okay I hacked some stuff up to have linux booting again I maybe can give the device tree series another spin tomorrow

09:54 <sven> iirc i just need a single mmio location

09:55 <sven> but i habe to be able to read and write to that location

10:22 <jannau> so we need the mmio resourse mapped. I don't think we can use the platform resource helpers for it unless we change the multi-die support. Can currently only think of ugly hacks orcomplicated solutions

10:23 <jannau> we could probably start with supporting thunderbolt only on the first die

10:56 <sven> fwiw, in the rewrite branch not even usb3 will work right now

11:30 <jannau> bah, I misremembered and thought usb3 was already working

11:31 <jannau> money quote from https://lpc.events/event/18/contributions/1721/ (Multi-sized THP performance benchmarks and analysis on ARM64): "We would recommend the use of a kernel with 16K page size as an optimal solution ..."

12:28 <chadmed> i wonder how that squares with commercial interest in keeping the door open to "easy" x86 emulation
