Arch Linux User Repository

Note for anyone who has a Polaris GPU (Radeon RX 5xx) debugging issues with this package; Packages that use OpenCL like clinfo or davinci-resolve-studio will need you to downgrade opencl-amd to 1:5.7.1-1 as well as amdgpu-pro-oglp to 23.10_1620044-1 to avoid coredumps & segfaults.

DVR would not open unless these 2 packages were downgraded (along with their dependencies). Had to figure it out the hard way after hours using valgrind and rebooting over and over. Hopefully someone else will not have to pull their hair out trying to resolve their issue.

For some reason, with this, clinfo just segfaults on my Artix install. Luckily, I was able to get the LD_DEBUG output (https://sperg.funny.cl/cdn/lddebug.txt), but it still segfaults even then. Seems like it's loading all the correct libraries. ICYW, here's the lddebug.txt from a chroot into my Arch install: https://sperg.funny.cl/cdn/arch_lddebug.txt (could boot into it directly and get it but cba rn)

The error fish gives specifically is:

fish: “LD_DEBUG=all clinfo 2> lddebug.…” terminated by signal SIGSEGV (Address boundary error)

So yeah, I don't know what's going on. However, one thing I'm particularly worried might be the problem is that nothing in rocm-device-libs archive gets installed. Though, I tried installing it to the corresponding directory but that didn't seem to work. Which means it's probably something else, or something with my Artix install. But I've got all the necessary stuff installed, numactl, ocl-icd, etc...

Also @gsus those are warnings not errors. I also get those for all of the libambd* libraries, on both my Artix and Arch installs, so you don't need to set the execution bit, in fact, you usually shouldn't do that for a library, and it wouldn't really do much since it's basically just a bunch of symbols and function definitions.

edit: The last line of the lddebug.txt says this: binding file /usr/lib/libamdocl64.so [0] to /usr/lib/libstdc++.so.6 [0]: normal symbol '_ZNSt8ios_baseD2Ev'

I can't tell if this specifically is crashing it, but it might be. Looks like it's trying to link/bind ios_base or something.

edit2: dmesg log says this: [ 5148.574644] clinfo[24744]: segfault at 8 ip 00007f33d50462b4 sp 00007fffa86b0f90 error 4 in libamdocl64.so[7f33d4faa000+db000]

So the error is in libamdocl64.so. Maaaayyybeee a missing library? I'd at least expect that to say "failed to open shared object" or something.

Directly after this message, it also says: [ 5321.488236] Code: 3b 44 24 08 73 08 89 5c 24 0c 89 44 24 08 8d 43 01 48 8b 55 00 48 89 c3 48 3b 04 24 72 a8 8b 44 24 0c 48 8d 04 40 48 8d 14 c2 <48> 8b 42 08 48 8d 0d 81 f5 07 00 4c 8b 0a 49 89 87 f0 05 00 00 48 which I don't understand in the slightest. Clearly it's some hex, maybe the <48> is like a bad instruction or byte or something, since it's the only one in <>? But there ARE other 48's there, so I've got no clue...

edit3: That last message is some hex in the libamdocl64 library. Specifically, it starts at offset 0x0B128A, and the <48> thing is at offset 0x0B12B4. That's the only place it occurs. So yeah, I think it's the area where it's segfaulting. Later, I might try to grab the assembly and see what's there? Maybe that'll help? Who knows

edit4: Here's the assembly file: http://sperg.funny.cl/cdn/libamdocl64.asm

Also, here's a snippet from that for 0x0B128A to 0x0B12B4:

   b128a:   3b 44 24 08             cmp    0x8(%rsp),%eax
   b128e:   73 08                   jae    b1298 <clCreateContextFromType@@OPENCL_1.0+0x3ac28>
   b1290:   89 5c 24 0c             mov    %ebx,0xc(%rsp)
   b1294:   89 44 24 08             mov    %eax,0x8(%rsp)
   b1298:   8d 43 01                lea    0x1(%rbx),%eax
   b129b:   48 8b 55 00             mov    0x0(%rbp),%rdx
   b129f:   48 89 c3                mov    %rax,%rbx
   b12a2:   48 3b 04 24             cmp    (%rsp),%rax
   b12a6:   72 a8                   jb     b1250 <clCreateContextFromType@@OPENCL_1.0+0x3abe0>
   b12a8:   8b 44 24 0c             mov    0xc(%rsp),%eax
   b12ac:   48 8d 04 40             lea    (%rax,%rax,2),%rax
   b12b0:   48 8d 14 c2             lea    (%rdx,%rax,8),%rdx
   b12b4:   48 8b 42 08             mov    0x8(%rdx),%rax

meaning that if my "theory" is correct, mov 0x8(%rdx),%rax is segfaulting it. Fish mentioned address boundaries, so it might trying to be moving a value into an unallocated RAM address or something, or one it can't access?

the version of the package is 20.45.1164792-3

the errors of the ldd -v /usr/lib/libamd*

ldd: atención: no tiene permiso de ejecución para /usr/lib/libamd_comgr.so ldd: atención: no tiene permiso de ejecución para /usr/lib/libamd_comgr.so.1 ldd: atención: no tiene permiso de ejecución para /usr/lib/libamd_comgr.so.1.7.0 [...] (in english is "you don't have execute permission to")

Maybe I need to set the execution bit to the libraries?

here is the output.

@gsus what version of the package do you use? I don't see it trying to load libamd_comgr.so.1 at all.

edit: also try a ldd -v /usr/lib/libamd* and see if it gives errors.

Hi @luciddream here is the lddebug.txt

https://filedn.com/lsGYnWmDn67jepFm0Ehk7z0/lddebug.txt

Hi @gsus, can you run LD_DEBUG=all clinfo 2> lddebug.txt and upload it somewhere so we can see if something is missing from the package?

@gsus Downgrade this package to version 20.40, and stay there forever.

For my RX5500 XT clinfo shows No devices found in platform [AMD Accelerated Parallel Processing?] opencl-amdgpu-pro-pal was works but the package opencl-amdgpu-pro-pal not exist anymore

Makes sense. The issue is that PhoenixMiner (and I assume Claymore too) now fail to work, immediately complaining that they couldn't build the OpenCL program, e.g. "Failed to build program: clBuildProgram (-11)" and such. Works fine with 20.40/PAL.

There's nothing odd about it, the new version uses ROCM (HSA - Heterogeneous System Architecture) stack - while the old driver was using PAL (Portable Abstraction Layer)

What issues do you have with the new version? If it doesn't work you can still download the old PKGBUILD from the sticky comment and use that one.

edit: Also check this comment from bridgmanAMD - he is more qualified to answer all questions about this version.

This broke things for me, oddly enough it's showing a lower OpenCL version than the previous version did (2.0 vs 2.1). The driver version doesn't list PAL anymore either which I thought it did before. This one shows - 3188.4 (HSA1.1,LC) where as the 20.40 PAL driver shows 3180.7 (PAL,HSAIL).

Something changed AMDs side, or a change of build process here?
