<Myy> Meow
<Myy> I released patches and cross-compiling scripts for 4.13 kernels on RK3288 systems, including the latest r19p0 Mali kernel drivers. https://github.com/Miouyouyou/RockMyy
<mmind00> Myy: nope ... the driver should be fixed
<Myy> Any hint on how it should be fixed ?
<mmind00> Myy: i.e. there is only one clock, the dt-binding therefore does not specify a clock-names property
<mmind00> Myy: the driver code (clk_get(...) ) needs to be fixed to honor the (now) official binding
<Myy> Alright. Does that apply to any board whatsoever ? If that's the case, I'll just patch the driver then
<mmind00> Myy: yes ... in general the dt-binding (for example Documentation/devicetree/gpu/*) is the authoriative thing ... and drivers then implement this binding
<mmind00> Myy: in out of tree things like the mali vendor driver this paradigm is often just not followed
<Myy> Ok. I'll try to fix this then. Do you know any driver (just right now) that does the right thing, so I could do a Monkey see, Monkey patch :3 ?
<mmind00> Myy: same is true for the Utgard binding (mali400 etc), which differs a lot from what the old vendor drivers do
<mmind00> Myy: just grep for the clk_get in the driver source and replace the "clk_mali" with NULL in it
<mmind00> Myy: i.e. NULL tells clk_get to just get the first clock
<Myy> Alright. I'll give that a try !
<Myy> I already had to patch their IRQ names fetching methodology, which only worked with uppercase IRQ names.
<Myy> Okay, this is patched. I'll recompile a new kernel with (ugly) test fixes for Tinkerboards reboot issues and give it a try.

<Myy> Well, looks like the Mali patch is working... I'll try to play with the frequencies, through /sys, see if it borks up or not.
<Myy> Alright, glmark2 DRM works, using Rockchip's wayland Mali drivers so I'll consider that it works.
<Myy> Anyway, thanks for these informations.
<Myy> Oh, github is down
<Myy> Alright, here's the patch for those who'd like to integrate the latest Mali Midgard kernel drivers with 4.13 kernels : https://github.com/Miouyouyou/RockMyy/blob/master/patches/kernel/v4.13/0005-Remove-the-dependency-to-the-clk_mali-symbol.patch
<Myy> Will there a release of Rockchip's Mali DDK that includes Vulkan support ? The official ARM Mali team seem to have release one specific version of Midgard drivers that include the Vulkan symbols (and code it seems).

<Myy> Meanwhile, I've advertised this last patch on the ARM Community (Since they don't seem to publish their GPL kernel driver sources through their Github company page...)
<Myy> Well, see you everyone !
