<lvrp16> narmstrong: is the "What's missing" section still a valid state of things? https://docs.kernel.org/gpu/meson.html

<chewitt> lvrp16 looks reasonable
<chewitt> that's only drm things though :)
<lvrp16> chewitt: those things are not implemented correct?
<lvrp16> chewitt: what else?

<Daanct12> does s922x still have amlogic cheats?
<Daanct12> since i recently discovered about that

<narmstrong> @lvrp16: indeed most of the doc is outdated
<narmstrong> Daanct12: no, now the frequency is real and has been validated, Linux now handles the frequency scaling

<chewitt> Danct12 the older GXBB/GXL/GXM devices report 2.0GHz instead of the actual 1.5GHz, but G12 devices (S905X2/Y2/D2 and S922X) all report correct
<chewitt> most S922X are moderately overclockable too, via device-tree changes

<lvrp16> narmstrong: so those missing things are or are not implemented?
<narmstrong> lvrp16: most are implemented, the only missing bits are HDR management between planes and HDCP

<Daaanct12> chewitt, narmstrong: ty for response, just discovered about that yesterday so i have to ask
<Daaanct12> i was planning on doing a thermal mod for my gt-king, and i was planning on overclocking it to it's best as it could go, how far people have gone in frequency in one of these things?

<narmstrong> haven't tested, my goal was to have it working nominally without crashing :-p
<Daanct12> i guess that's already achieved? :) the last i heard was that the frequent crashing issue was because of linux touching memory address that it shouldn't have do
<Daanct12> and that one was allocated to arm tf

<chewitt> It was only affecting the GT-King when booted from vendor u-boot
<chewitt> the overclock rates depend on whether it's a Rev B or Rev C chip .. C's will reach 2.4GHz if pushed
<chewitt> but depends on good thermals
<chewitt> I would personally focus on reliability not speed
<chewitt> IIRC the GT-King(s) have reasonable heatsinks, but I wouldn't hurt to redo the coupling with an appropriate amount of good thermal paste
<chewitt> vs. the excessive blob of cheap crap that was probably done in the factory
