Description of problem:
1. By design, NVML does not support any 32-bit architecture.
2. Due to dependency on xmmintrin.h and because of using some inline assembly, it builds only for x86_64 at the moment. Other 64-bit architectures could also be supported, if only there is a request for that, and if somebody provides the arch-specific implementation of the low-level routines for flushing to persistent memory.
This bug appears to have been reported against 'rawhide' during the Fedora 25 development cycle.
Changing version to '25'.
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
This bug appears to have been reported against 'rawhide' during the Fedora 30 development cycle.
Changing version to '30'.
We (Intel) generally don't port software to foreign architectures by our own efforts, merely accept and review external patches. Yet, PMDK already has support for ARM64 -- it compiles but doesn't (out of the box) work, and superficial investigation suggests that it's a problem with dependencies rather than PMDK itself.
* valgrind crashes with SIGILL upon encountering any cache flushes, even those supposed to be supported by any 64-bit ARM machine. A very preliminary patch is at https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=930708;filename=0001-Fix-SIGILL-on-dcache-flushes-on-arm64.patch;msg=5
* valgrind reports false positives in helgrind and drd tests
* gcc apparently miscompiles (or possibly reveals a bug/undefined behaviour?) parts of vecx-related code at -O2 or higher. This can be avoided by building with clang or by lowering gcc's optimization level to -O1, -O0 or -Og.
(I'm posting these findings in case someone is willing to expend effort to fix the above issues.)
