<Stat_headcrabed> Seems JH7110's display controller has cache coherence problem?
<Stat_headcrabed> Terrible

<Tenkawa> Stat_headcrabed: I haven't seen any good reports on the IT GPU/Display implementations on Risc-V SBC's yet

<conchuod> Stat_headcrabed: Got more on that?
cousteau` is now known as cousteau
<Stat_headcrabed> conchuod: There's a fix for cursor flickering in downstream DC8200 driver, and the fix is that cache flushing
<Stat_headcrabed> So high possibility that this is a coherence problem

<Stat_headcrabed> Also from the system architecture image here: https://doc-en.rvspace.org/JH7110/TRM/JH7110_TRM/system_architecture.html
<Stat_headcrabed> Display controller has AXI host port directly connected to NOC rather than front port
<Stat_headcrabed> Same for ISP, VENC, VDEC and GPU
<Stat_headcrabed> Btw, how to mark a peripheral as non-coherence in mainline?

<conchuod> Put "dma-noncoherent" in the device or bus node

<Stat_headcrabed> So I think we need Esmil's JH7100 cache series land for this?

<Esmil> ..if anyone wants their Pioneer to boot faster ;)
<bjdooks> can the display memory be mapped write-through instead of write-back? might flush out updates faster to dram

<jrtc27> I don't think the JH7110 does Svpbmt
<jrtc27> unless it crept into newer versions of SiFive's U74
<jrtc27> if StarFive still managed to screw up cache coherence on their second go at the same SoC that's pretty sad and poor

<sorear> i kind of hate that you need Svpbmt for PCIe
<sorear> if you are accessing this channel through Matrix and want to continue doing so after EMS’ bridge goes away at the end of the month, please make yourself known
bestcharlemagne has joined #riscv
<jrtc27> you don't need Svpbmt if you don't care about performance :)

<ball> What's a Svpbmt?
<Tenkawa> its a cpu extension
<ball> Ah. Are there any sensible (or interesting) alternatives to PCIe?
