05:35 <AreaScout> Morning, the impossible is unbelievably possible Panfrost running on T628 https://forum.odroid.com/viewtopic.php?p=350810#p350810

05:36 <HdkR> Nice

05:38 <AreaScout> I couldn't believe my eyes when I saw it :)

08:43 <macc24> well then that opens up possibility of cadmium port for exynos chromebooks... ugh

09:52 <robmur01> Hmm, I thought some folks were still hitting lockup issues on XU3/4, regardless of the coherency problem?

09:52 <robmur01> FWIW it's been running "well enough" on T624 for a long time now :)

10:10 <AreaScout> The only information I had all the time was that it didn't work, someone got kmscube working but most of the time it was just crashing

10:28 <stepri01> v5.18 is the first released kernel with 'support' for dual core groups

10:28 <stepri01> where 'support' means during off the extra cores and not using them...

10:28 <stepri01> see 6e55d273708b ("drm/panfrost: initial dual core group GPUs support")

10:29 <stepri01> s/during/turning/

10:36 <AreaScout> wow is that cool, still exited !

12:14 <cphealy> stepri01: regarding 6e55d273708b ("drm/panfrost: initial dual core group GPUs support"), for those running Bifrost (G52) with kernels older than 5.18, is this patch relevant or is it specific to Midgard?

12:16 <stepri01> It's specific to early Midgard. The Midgard architecture has a concept of "core groups" that was effectively removed long before Bifrost. It causes problems because the cores are not coherent between the groups.

12:22 <cphealy> tnx stepri01
