SBC with RISC-V & Vector 1.0: no commands starting with "v" (for vector?) in generated sabctools so library #116

Closed sanderjo closed 4 months ago

sanderjo commented 4 months ago

pinging @animetosho

I received my "Banana Pi BPI-F3 SpacemiT K1 8 Core RISC-V", which should have risc-v vector 1.0 (aka RVV 1.0). Running Armbian Ubuntu noble on it.

After python3 setup.py build, I do not see commands starting with "v" (assumption: vector commands) in the objdump of the generated sabctools .so libary.

Wrong method? Wrong gcc? Wrong ... ?

Help appreciated.

You generally want to be running bleeding edge for RISC-V, so try upgrading to GCC 14. GCC 13 lacks typecast intrinsics, so it's explicitly disabled there.

Clang 14+ should also work.

sanderjo commented 4 months ago

I installed gcc-14 etc, made it active, did the build, but still no commands starting with "v" in the objdump-disassembly.

So can you help further? And: the objdump method: is that correct, and does it give v-commands in your output?

Installed gcc-14:

sudo apt install gcc-14 g++-14

via update-alternatives set gcc-14 etc to active:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-14 90 --slave /usr/bin/g++ g++ /usr/bin/g++-14 --slave /usr/bin/gcov gcov /usr/bin/gcov-14 --slave /usr/bin/riscv64-linux-gnu-gcc riscv64-linux-gnu-gcc /usr/bin/riscv64-linux-gnu-gcc-14

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-13 70 --slave /usr/bin/g++ g++ /usr/bin/g++-13 --slave /usr/bin/gcov gcov /usr/bin/gcov-13 --slave /usr/bin/riscv64-linux-gnu-gcc  riscv64-linux-gnu-gcc /usr/bin/riscv64-linux-gnu-gcc-13

Checking ... looks good ... version 14 is now default:

Thanks for trying that out.

And: the objdump method: is that correct, and does it give v-commands in your output?

That should be a sufficient indicator.

Are you able to check what commands are being passed to the compiler exactly? Not sure if setuptools offers the option by default.

You can also try with rapidyenc directly - this should help isolate whether the build config has an issue.
If you try rapidyenc directly, after the cmake .. command, you can use make VERBOSE=1 which should show the commands being executed. In the list, the de/encoder_rvv files should have the -march=rv64gcv option set.

animetosho commented 4 months ago

You should also be able to see ==> Checking support for flag: -march=rv64gcv in the build log for sabctools.
If using pip to install/build, it seems like passing the -v option will display all issued commands. Look at the commands used to build decoder_rvv.cc

My attempt to cross build isn't working due to setuptools sending flags the compiler doesn't like.

My attempt to cross build isn't working due to setuptools sending flags the compiler doesn't like.

I can give you ssh access to my RVV 1.0 hardware. Preferably via IPv6, as I'm behind IPV4-CGNAT.

And if you want, I can give you root access. The system is 2 days old, so clean, and I can reflash/reinstall if things go wrong.

Ah, progress ... via an ugly hack: forcing "-march=rv64gcv" as cflags in setup.py:

sander@bananapif3:~/git/sabctools$ diff setup.py.ORG setup.py
123a124,125
>             cflags.append("-march=rv64gcv") # Sander hack
>

... and ... bingo ... v-commands in the resulting sabctools .so.

So detecting or setting -march=rv64gcvis not going well in the non-hacked setup.py?

Ah, I think I messed some code in setup.py. Could you try replacing all instances of gcc_rv_flags with gcc_flags in that file, and try again?

Could you try replacing all instances of gcc_rv_flags with gcc_flags in that file, and try again?

Bingo! The resulting .so contains v-commands! And compiling is now a normal time (1 minute), not 3+ minutes like with my ugly hack (where each compile line had that option forced in).

$ sed -i -e 's/gcc_rv_flags/gcc_flags/g' setup.py Looks good:

sander@bananapif3:~/git/sabctools$ diff setup.py.ORG setup.py
291c291
<                 "gcc_rv_flags": gcc_rvv_flags,
---
>                 "gcc_flags": gcc_rvv_flags,
296c296
<                 "gcc_rv_flags": gcc_rvzbkc_flags,
---
>                 "gcc_flags": gcc_rvzbkc_flags,

WAIT: gcc_rvv_flags (double v) should still be there? It works, so looks good, but just checking ...
