GPU Compute / Accelerators / Re: GPU & disk encryption?
« on: January 07, 2023, 06:44:15 pm »
I have a somewhat similar system and solved the problem with
Code: [Select]
modprobe.blacklist=ast video=offb:off console=tty0.

Didn't know I can ditch amdgpu.aspm=0 now. Thanks for the information! I am always looking forward to get as close to stock debian sid with as few tweaks as possible.

Hi MauryG5, I am glad you got it running!
Using debian as well and compiled my latest kernel as follows:
Code: [Select]
cd
mkdir mylinux
cd mylinux
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.17.4.tar.xz
tar xf linux-5.17.4.tar.xz
wget http://ftp.de.debian.org/debian/pool/main/l/linux/linux-config-5.17_5.17.3-1_ppc64el.deb

cp usr/src/linux-config-5.17/config.ppc64el_none_powerpc64le.xz ./
xz -d config.ppc64el_none_powerpc64le.xz
cd linux-5.17.4
curl -o fpu_exeption_fix_for_ppc64le_with_amdgpu.patch 'https://forums.raptorcs.com/index.php?action=dlattach;topic=332.0;attach=388'
patch -p1 < fpu_exeption_fix_for_ppc64le_with_amdgpu.patch
cp ../config.ppc64el_none_powerpc64le .config
echo CONFIG_PPC_4K_PAGES=y >> .config
make olddefconfig
make -j32 bindeb-pkg
sudo dpkg -i ../linux-headers-5.17.4_5.17.4-1_ppc64el.deb ../linux-image-5.17.4_5.17.4-1_ppc64el.deb

@MauryG5 Download a kernel source tree of choice and unpack it. Then download my patch and save it inside the top directory of the kernel source. Now apply the patch as follows from inside of the kernel source directory:
Code: [Select]
patch -p1 < fpu_exeption_fix_for_ppc64le_with_amdgpu.patchNow configure and compile as usual.

Warning: I don't know what my patch exactly does. It was mere guess work. I found the solution by looking at resembling code in the file drivers/gpu/drm/amd/display/dc/dcn303/dcn303_resource.c applying it to the other two files and the error was gone. I have no clue if my patch has any implications whatsoever. Use at your own risk.

The similar addition in the other file core_types.h does not trigger the error. This means that the following part of the problematic commit 9fa0fb77132fe9e83f2b357fd5a2b16293a5b9ee does not trigger the error:

commit 9fa0fb77132fe9e83f2b357fd5a2b16293a5b9ee
Author: Meenakshikumar Somasundaram <meenakshikumar.somasundaram@amd.com>

    drm/amd/display: USB4 DPIA enumeration and AUX Tunneling
   
    [WHY]
    To enable dc links for USB4 DPIA ports and AUX command tunneling
    for YELLOW_CARP_B0.
   
    [HOW]
    1) Created dc links for all USB4 DPIA ports in create_links().
       dc_link_construct() implementation is split for legacy DDC and DPIAs.
       As usb4 has no ddc, ddc->ddc_pin will be set to NULL for its dc link
       and this parameter will be used to identify the dc links as DPIA. The
       dc link for DPIA is further to be enhanced with implementation for link
       encoder and link initialization.
    2) usb4_dpia_count in struct resource_pool will be initialized to 4 in
       dcn31_resource_construct() if the DCN is YELLOW_CARP_B0.
    3) Enabled DMUB AUX via outbox for YELLOW_CARP_B0.

They'd like a bisect on that bug report, any chance you could do that since you have a reproducible issue on your specific hardware?

I will try. Never bisected before. Well, then git bisect start ...
