Kernel panic - display black #2

Closed phodina closed 11 months ago

phodina commented 11 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 11 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 11 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 11 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
