02:55 <alyssa> ....I'm supposed to get a render node for a rockchip DRM device, right...?

02:59 <alyssa> ----Or is that just a ChromeOS weridness?

09:01 <mmind00> alyssa: nope, only a cardX for the kms device ... the render-node supposedly comes from the render-only device (panfrost in your case obviously)

09:01 <mmind00> alyssa: at least that is how it looks on my mali-utgard based boards

11:17 <ezequielg> mani_s: we need to enable tsadc on rock960

11:17 <ezequielg> do you think 95C default shut temp is ok?

11:20 <mani_s> ezequielg, in the vamrs kernel tree, it has been 110C

11:20 <mani_s> https://github.com/96rocks/kernel/blob/rock960-4.4-dev/arch/arm64/boot/dts/rockchip/rock960-model-ab-linux.dts#L674

11:20 <mani_s> So we should stick to it

11:21 <ezequielg> that is higher than 95C

11:22 <ezequielg> sounds quite high

11:26 <mani_s> ezequielg, yeah but it does generate a lot of heat

11:28 <mani_s> I can check with Tom regarding this value

11:29 <ezequielg> yeah, let's check that.

11:29 <ezequielg> just in case.

11:29 <ezequielg> mani_s: fwiw, I had to add a cooler here to avoid shutdown when doing some builds on the board.

11:30 <ezequielg> the thermal sink is a bit small i think.

11:33 <ezequielg> mani_s: mmind00: little patch for audio sent.

11:34 <mani_s> ezequielg, turns out to be very simple ;-)

11:45 <DuClare> I wonder if anyone ever booted mainline kernel with op-tee on rk3288..

12:02 <mmind00> DuClare: don't think so ... but converting to either atf (their armv7 support) or optee providing psci support sounds quite tempting :-)

12:02 <mmind00> instead of rolling the kernel-side smp + suspend (especially as deep suspend involves the sram)

12:04 <DuClare> Oh atf has armv7 support?

12:04 <DuClare> Everything I read said otherwise :(

19:56 <alyssa> ezequielg: Unclear

19:56 <alyssa> One is vgmem and the other is the VOP, maybe?

19:57 <ezequielg> my question is: why do you need render nodes?

19:58 <ezequielg> currently in mainline, the kms driver (drm/rockchip) won't give you a render node.

19:58 <ezequielg> you can get one from vgem.

19:58 <ezequielg> unclear what for.

20:01 <ezequielg> alyssa: ^

20:05 <alyssa> ezequielg: I don't. I thought I did when I posted the message; turns out I misread the code. I don't know why we're still talking about it :p

20:05 <ezequielg> lol

20:06 <ezequielg> you don't indeed
