| markos | actually, as a first hacky attempt one can avoid a new triplet andd just rebuild all packages just by enabling features, gradually but manually, starting with gcc/glibc/etc. As a PoC. This is exactly what I did for armhf bringup, back in 2008, I rebuilt most of Debian just by switching from softfp to hardfp. The triplet was just added later where we used the first repo as a basis to rebuild the archive and satisfy dependencies | 10:02 |
|---|---|---|
| markos | so in order to build a VSX-less distro, it's possible to do just that without a new triplet | 10:03 |
| markos | tbh, I wouldn't use a new triplet at all, as that would mean yet another port | 10:03 |
| markos | I would still keep the same triplet and file a ton of bugs to all the packages that assume VSX to force them to make it optional or dynamic | 10:04 |
| markos | it would take a while, but in the long term it's a far better solution than having multiple ports for what is essentially the same ABI | 10:05 |
| markos | pretty sure the distro people would be against that also | 10:05 |
| lkcl | it's really not the same ABI. | 10:11 |
| lkcl | EABI 1.9 makes VSX registers mandatory | 10:11 |
| lkcl | which is a massive showstopper | 10:11 |
| lkcl | EABI 1.9 is where it all went to hell in a handbasket. VSX was made mandatory. 128-bit hardware was made mandatory. | 10:15 |
| lkcl | the process you describe is suitable for a first-stage bootstrap | 10:15 |
| lkcl | what i was describing was more... a second-stage | 10:15 |
| lkcl | that would kiinda make the first stage (cross-compiling) slightly less hassle | 10:16 |
| markos | as an internal process that would work, but I'm thinking that distros would find it very hard to accept yet another Power port (already 3, 4 if one counts the now defunkt powerpcspe port) | 10:18 |
| markos | Debian that is | 10:18 |
| markos | I'd rather we fixed ppc64le proper and have it support all optional variants, obviously only for future revisions of the ABI | 10:18 |
| lkcl | the amount of work involved in that is one hell of a lot. tracking down and re-enabling code that was removed 6+ years ago? | 10:25 |
| lkcl | my feeling is that it would actually be better *to* get them to say "god no we're not having that" | 10:25 |
| lkcl | and for *other people* to suggest, "actually a better solution would be to re-enable the code that was removed which allows variants" | 10:26 |
| lkcl | so that they feel "involved" | 10:26 |
| lkcl | i appreciate that may sound silly | 10:38 |
| lkcl | to *actively* seek out people to say "no" | 10:39 |
| lkcl | but it could help avoid the risk of the "let's say no to the very first thing these n00bs say" syndrome | 10:40 |
| markos | maintaining a full port is a hell of a lot more work than actually fixing the dozen or so packages that would really require fixing | 11:08 |
| markos | in most cases it's indeed the case of fixing a minor #ifdef | 11:08 |
| markos | in a few selected packages it will be a lot more work but that can be done, eg. by bounties | 11:09 |
| markos | first identify and then pay the actual devs or other contributors to provide a fix for that | 11:09 |
| markos | it has been done in the past | 11:09 |
| markos | believe me, you really *don't* want to maintain a full port for a long time, creating a POC is one thing, long term commitment is quite a different beast | 11:14 |

| Gayatri | I am creating Libresoc environment at Debian latest version. i can successfully completed all instruction from dev script and then run "python3 src/openpower/decoder/isa/test_caller.py > /tmp/log" . I am getting message as "Ran 23 tests in 130.528s and OK (skipped =1). | 14:28 |
| Gayatri | why 1 has been skipped. what can i do for that | 14:28 |
| programmerjake | tests are often marked skipped when they're known to be broken or out-of-date, don't worry about it | 14:30 |
| Gayatri | can you please advice where do i execute the run of "SOC--Makefile" script file | 14:32 |
| Gayatri | then after what can i do | 14:33 |
| lkcl | once you have a libresoc.v then you can substitute that into microwatt builds | 14:35 |
| lkcl | there are instructions on the wiki which you can find and follow | 14:35 |
| Gayatri | where can i find this libresoc.v file | 14:40 |
