Kernel panic - display black #2

Closed phodina closed 6 months ago

phodina commented 6 months ago

Hi @map220v,

I've compiled the kernel 6.6 with the defconfig and the panel turns on after boot.

However, if the kernel attempts to suspend the panel I get the following panic.

Do you observe the same issue?

Here's the assignment of the clock in the DTS https://github.com/map220v/sm8150-mainline/blob/nabu-6.6/arch/arm64/boot/dts/qcom/sm8150.dtsi#L3735

map220v commented 6 months ago

I didn't had this issue when i suspended/resumed few times, I thought https://github.com/map220v/sm8150-mainline/commit/16a2600d9bdd84abee45b8a26008dcbf7626554d also fixed DSI clock issue. For stability use kernel 6.1, kernels starting from 6.2 are broken for sm8150 and still have issues with dsi clocks being stuck in on/off state on suspend/resume, bluetooth uart failing to start and ufs clocks being stuck in off state most of times when booting with dual dsi.

phodina commented 6 months ago

I've used the branch nabu-6.0-rc1 but I do have similar issue that the screen just can't be powered on again.

What commit from your view is stable enough?

map220v commented 6 months ago

In my repo DSI suspend and resume should work in nabu-5.19 branch.

There is also repo that is still being maintained https://github.com/maverickjb/linux-6.1.10 it has patches for type-c(otg) support, working dsi resume/suspend and secondary usb with wn8031f for xiaomi's keyboard support
