[Bug 1790856] Re: [MIR] pmdk
Thanks for explaining more details and backgrounds Adam! But promotion to main isn't really done per-architecture. That only exists via e.g. having a package build only x86 binaries and then promoting it. I've not yet seen a package building x86,arm64,ppc64 binaries but then promoting only some of the architectures. Therefore I suggest for now lets push src:pmdk and binary:libpmem1 and binary:libpmem1-dev to main, but leave the others in universe for now. That will not break the back of the "middle-tier-libs" like pmempool, libpmemobj, ... The will still be in a package that has it's source in main being monitored and cared for - just a slightly less hard-commitment. To me it seems to be the cleanest cut we can make right now. My MP that I linked above would achieve exactly that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1790856 Title: [MIR] pmdk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pmdk/+bug/1790856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1790856] Re: [MIR] pmdk
Sorry if I was unclear: libpmemobj and friends are well-tested on amd64, it's only the ppc64el port of those that's very new (mostly because of many hardcoded x86 assumptions, like page and especially cacheline size, that are untrue on ppc). The library has gone through six years of development already, thus can be considered pretty solid. pmempool is a tool (and library) for managing libpmemobj pools. The rest (pmemblk and pmemlog) are somewhat less useful but still are a part of the product. Thus, I'd recommend skipping only parts that are experimental: rpmem on amd64, and anything but perhaps libpmem on arm64 and ppc64el. The debug libs belong in universe, too, I guess. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1790856 Title: [MIR] pmdk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pmdk/+bug/1790856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1790856] Re: [MIR] pmdk
Version 1.8 has just been released. As I mentioned before, besides
splitting out deprecated and out of scope for PMDK libvmem and
libvmmalloc, support for ppc64el has been added, thanks to Lucas
Magalhães of IBM.
While the ppc64el port is marked as experimental, this is mostly due to
higher-level libraries being untrustworthy (they do pass the testsuite,
but are way too new and complex). As for low-level libpmem, the ppc
specific code is short and looks obviously correct. It is also what
current external projects want (qemu, fio, ceph). Especially because of
qemu, I believe you'd want libpmem{1,-dev}:ppc64el in main.

[Bug 1790856] Re: [MIR] pmdk
The hardware is commercially available for more than half a year, thus
proper support is more urgent than it was when this bug was initially
filed. At this time, the DIMMs work only with large servery machines,
for which large numbers of qemu VMs is one of most widespread uses.
Thus, it's important that qemu can use NVDIMMs in non-volatile modes.
The jemalloc issue: it's not used by libpmem{1,-dev} which is the part
you'd want to promote to main first. Also, it's gone in the version
that will be released in January/February.
As for other architectures: arm64 has been fixed and passes tests
(although there's AFAIK still no hardware), ppc64el is being worked on.
If you want to promote only libpmem for now, pmdk-convert is not
required.
On the other hand, the dependency on ndctl (both libndctl and libdaxctl,
built by that source) is now effectively mandatory.

[Bug 1790856] Re: [MIR] pmdk
PMDK is since recently in Debian, maintained by me. Version 1.5 (Ubuntu still has only 1.4). Real architecture support is limited to amd64. The nature of this software (mmapping hundreds of GB -- or terabytes -- of pmem) means i386 and armhf are outright out. Upstream support for arm64 is unmaintained and has mostly bitrotten; as far as I know there's no hardware capable of using nvdimms, at least as persistent mode is concerned (it might be possible to use the dimms in volatile mode?). I asked riscv64 people, there are no cache control instructions in the ISA and no platforms with unstandardized support can flush all layers of the cache -- thus even anticipatory porting of PMDK to riscv64 is currently impossible. I have no idea about ppc64el but at least ndctl is rumoured to work -- no one ported PMDK yet, though. Wrong-endian (s390x) would probably require substantial work. libpmemcto has became even more experimental and found a nice home in /dev/null. libpmemobj-cpp has been split out as a separate package; that part is not very advanced thus you might skip it for now. There's also pmem-convert for upgrades between major versions; its packaging will be complex but you'd want that part once I'm done with it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1790856 Title: [MIR] pmdk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pmdk/+bug/1790856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1790856] Re: [MIR] pmdk
To add one more reason to do this like "now" (=early 19.04) from my personal POV. While rare today, looking into the future I'd think the availability of nvdimms will rise. So looking forward to 20.04 we have multiple options: - nvdimms are a thing by then, so we better start in 19.04 to get things right until 20.04 - nvdimms are a thing by then but pmdk is crap, we realize that and can take it out of main before 20.04 - nvdimms are a thing by then and get a huge boost of interest, we better start in 19.04 to be one of the few supporting it and due to that get some of that "attention" towards Ubuntu - nvdimms are identified to be crap, we realize that and can take it out of main before 20.04 ... This goes on, but for all of the thoughts that I had starting this in 19.04 would be the best option for our way to a great 20.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1790856 Title: [MIR] pmdk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pmdk/+bug/1790856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
