Problem with meson-pcie patch

VIM3
1

Hi @numbqq and @Frank

Seems there is a problem (at least for myself ) with a patch introduced by commit in Fenix build system

If I build a kernel with this patch I’m getting the following messages in my kernel log

And as result my NVME SSD stops working and isn’t visible to system

If I undo this patch - everything works absolutely fine and my system gets NVME SSD back

Tested on several kernels 5.15 and 5.16-RC8

@OldNavi I will check it

3

Just to mention - HW used: VIM3L → New M2X → NVME SSD.

4

@OldNavi

OK, I will check it today.

5

@OldNavi I tested it . This patch will make the SSD unusable. I will check this patch here and find a way to solve this bug. If you don’t need to use coral, you can remove this patch first.

Hi @Frank - thanks for confirming this defect, of course I don’t use coral and already disabled this patch.

Is there a timeline for getting this patch reverted in one or more of the existing Krescue images? Barring that, is there a known-good image I should try instead that isn’t using an ancient kernel?

I’m trying to evaluate my VIM3(L) boards alongside some other ARM SBCs for an embedded hardware application, but if I can’t use a mainline kernel + SSD it’s going to be a short and unsuccessful test for the Khadas option. (I’ll still use them for my hobby projects, but only those that don’t require more storage than the built-in MMC, which rules out anything server or media-related.)

So I went back down the list of images in Krescue and tried basically everything running a 5.x kernel…and the latest Ubuntu 20.04 GNOME image worked!

Now, I don’t need or want the GNOME environment for this project, but I can work around it and build a new golden image from here, at least to get through my evaluation.

try to use Generic ubuntu images via Krescue or fenix

http://dl.khadas.com/firmware/Krescue/images/Generic_Ubuntu-minimal-focal_Linux-5.16-rc2_arm64_SD-USB_V1.0.7-211122-develop.img.xz

and dont forget install mainline uboot into emmc or spi

Hi OldNavi, could you give me some idea how to disable this patch?

11

I’m not sure if that patch now in the latest mainline kernel? Better check with @Frank regarding that. And perhaps it is worth to know what kernel version you’re trying to build with Fenix.

Thanks! But now I can load the HP P410 raid card in newest mainline kernel no matter of this patch. I found that I need to boot khadas vim3 and then power on the PCIe 12v for raid card, finally restart khadas vim3 again. The raid card will be recoginzed in the system or the system be hung on pcie initialization and fail to start.

Sorry for the noise!
