Could you please start the miner by hand from a terminal without start.sh because I am not sure if this is a error message from the miner or your script.

Instruction non permise (core dumped)
user@MC002:~/Bureau/xmr-stak-amd-master/bin$
I have an "illegal instruction (core dumped)" error message
from xmr-stak-amd.
fireice-uk
commented on May 9, 2024
@QuentinHK0 Are you familiar with linux core dumps? If so can you please open the generated file in gdb like so:
gdb xmr-stak-amd <core-file>
When it loads issue following commands bt, list, and info locals and copy and paste the results.
Also please copy and paste the result of the command cat /proc/cpuinfo
from xmr-stak-amd.

commented on May 9, 2024
@QuentinHK0 What is the type of your gpu. Please change the language of your system to english else the error massages are hard to read.
@fireice-uk Could it be that there is an issue with the aes-ni detection and the miner crashes after the first share is found.
from xmr-stak-amd.
QuentinHK0
commented on May 9, 2024
@fireice-uk I can not locate the core-file , I read that it had to be generated in the current directory but there is nothing. i will make some research
@psychocrypt I try to change the language but the error message is still in french, for information the equivalent of "Instruction non permise" is illegal instruction.

QuentinHK0
commented on May 9, 2024
@fireice-uk i just read that the ubuntu kernel is configured to use apport to log coredumps and it writes core dump to /var/crash/_path_to_the_program_userid.crash, but it will only do so for applications installed from the main ubuntu apt repo. I think there is a way to get it from xmr-stack-amd, I'll look. do you know something about it ?
from xmr-stak-amd.
fireice-uk
commented on May 9, 2024
@psychocrypt That's my thinking exactly, however another option is gcc building in AVX instructions (it will do that in c++ code if march allows), I need a coredump to confirm which one it is.
@QuentinHK0
following commands will configure the kernel to dump into the current directory:
ulimit -c unlimited
echo './core_%e.%p' | sudo tee /proc/sys/kernel/core_pattern

@fireice-uk from clinfo we can see that it is an e5500 without aesni and from gdb we see that softaes is used. In the crashed function soft_aeskeygenassist() everything look fine for me, do you have any ideas?

@QuentinHK0
Can you post the result of cat /proc/cpuinfo (so that I know the exact cpu feature set)? and (inside of gdb core dump) layout asm ?
@psychocrypt
This is turning into an interesting detective story, unless GCC up-optimised my code to SSE4, there are only plain-old SSE2 instructions there.
In particular I'm thinking of those lines:
uint32_t X1 = _mm_cvtsi128_si32(_mm_shuffle_epi32(key, 0x55));
uint32_t X3 = _mm_cvtsi128_si32(_mm_shuffle_epi32(key, 0xFF));
In SSE4.1 they can be replaced by two PEXTRD instructions, which is what might be tripping up the code here.

@fireice-uk Hello ,
Sorry I did not have time to reply during the weekend. For information I use exactly the same configuration (mother board, graphic card, cpu) with windows 10 and wolf miner, everything work fine, so I do not think it comes from cpu features.

@QuentinHK0 can you make a screenshot? That would be most useful as context is sometimes relevant and this way you will get the nearby instructions too.
The problem here (if my hunch is correct), is that gcc is over-optimising the code, translating two SSE2 instructions into one SSE4.1 instruction that your cpu can't handle.

@fireice-uk we compiling with -O3 which is anabling auto vectorization by using -ftree-vectorize we can disable it for gcc with -fno-tree-vectorize. I will provide a pull request to test it in one to two hours.

Please run make install or copy the opencl folder from the reposetory to xmr-stak-test/bin. The old opencl folder is not compatible with the dev version.
Best would be to start again from cloning and running make install instead of make -j install. If it breaks at any step please post the error to avoid mixing code versions.

@psychocrypt I did not take the old opencl folder i use the one from
git clone https://github.com/psychocrypt/xmr-stak-amd.git

Thats fine. Could you please decrease the intensity in the config to 512

thx I will check this error today night on my pc.
In this case please copy the opencl folder to bin. And try to start the miner with intensity 512.

@QuentinHK0 Sorry I missed it. As you can see my hunch was correct =) it is crashing on PEXTRD instruction.
Quick fix to this problem is to pass -mno-sse4.1 at both C and CXX lines here https://github.com/fireice-uk/xmr-stak-amd/blob/master/CMakeLists.txt#L99
Interestingly, your CPU should support sse4.1, you can try updating your BIOS too.

@QuentinHK0 One final request - can you please post the output of gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g' -> this will help us to see if we can tweak gcc to handle odd cases like that one?

@fireice-uk Do I need to replace or add -mno-sse4.1 option at lines 98 and 99 ?

QuentinHK0
commented on May 9, 2024
@fireice-uk So i recompiled with arg -mno-sse4.1 , cmake . make install i put my old config.txt in bin folder and now it's ok, the program runs for 10 min without error. I did not exactly understand where the problem came from but thank's you and GG :)

@psychocrypt do you think an option of passing -march native might be advisable? His gcc is detecting the odd feature set correctly.
from xmr-stak-amd.
Panzerfather
commented on May 9, 2024
@fireice-uk Sorry to correct you with my first comment in this project, but the feature set isn't correctly detected by gcc. On the Pentium E5500 the SSE4.1 instructions are disabled via the hardware/microcode and as the values via cat /proc/cpuinfo correctly showed in #44 (comment), there is no SSE4.1 flag enabled. Also the intel data sheet for the Pentium E5500 doesn't list any SSE4.1 instruction set. Maximum is SSE3.
So as this is a gcc bug, it's more a question if this option will increase posted/asked issues when everyone could set it via cmake etc. ?

commented on May 9, 2024
@FireIce I think there is no need for an option with -march=native the user can put it to the environment before cmake is called.
# run this on a clean xmr-stk code
export CXXFLAGS="-march=native -mtune=native"
export CFLAGS="-march=native -mtune=native"
cmake .
make install

@Panzerfather No need to be sorry, please correct me if you see that I'm wrong. Please explain your reasoning in this case though. GCC will can and does generate instructions that the CPU it runs on can't handle (it can even compile ARM code). What this code snippet does gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g', afaik, is to display the flags that -march=native enables.
Compare the results of @QuentinHK0 output with my output generated on a haswell core:
-march=core2 -mmmx -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -mfxsr --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=2048 -mtune=core2 -fstack-protector-strong -Wformat -Wformat-security
mine:
-march=haswell -mmmx -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -mmovbe -maes -mpclmul -mpopcnt -mabm -mfma -mbmi -mbmi2 -mavx -mavx2 -msse4.2 -msse4.1 -mlzcnt -mrdrnd -mf16c -mfsgsbase -mfxsr -mxsave -mxsaveopt --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=3072 -mtune=haswell -fstack-protector-strong -Wformat -Wformat-security
Unless my reasoning is wrong here, -march=native would have disabled the see4.1 flag (which itself was enabled since we need to build with -maes to compile the code at all)
from xmr-stak-amd.

commented on May 9, 2024
@fireice-uk you are absolutely right in this case -march=native will disable the SSE4.1 flag because it looks what kind of flags the cpu can handle and enable them all, whatever this flag is needed or not. There is a good explanation what the -march=native flag does in gcc here or here. In most cases there shouldn't be anything wrong with this compiler option.
But as this project massively relies on correct SSE instructions I have doubts that this option can also have a negative effect on the performance and/or produces unexpected crashes/results as it will shorten the SSE registers when AVX/AVX2 features are also activated. This is documented in the Gentoo GCC Optimization Guide.
As @QuentinHK0 processor doesn't support AVX/AVX2 there is no problem at all for him to use this flag, neither with performance doubts nor untested results when the SSE registers are shorten for AVX/AVX2 instructions. But this unique for this kind of CPU which is also "out of support service".
I think @psychocrypt has the right solution for users which a) have such kind of problems discussed in this issue, b) want to try out other compiler flags to get the maximum performance out of this application.
