@vcunat:matrix.orgvcunatSounds risky.18:12:12
@vcunat:matrix.orgvcunatYou'd be punching a hole.18:12:32
@vcunat:matrix.orgvcunatThe cache is assumed to be closed on dependencies.18:12:46
@reckenrode:matrix.orgRandy EckenrodeI wonder if we need a `no broken signatures’ hook on Darwin.18:12:50
@vcunat:matrix.orgvcunat* The cache is assumed to be closed on dependencies. (or whatever you'd call the property)18:12:55
@reckenrode:matrix.orgRandy EckenrodeLike that symlinks one but for signatures.18:13:07
@emilazy:matrix.orgemily I see no alternative other than rerolling the hash for aarch64-darwin then 18:13:27
@emilazy:matrix.orgemilythough should try to rebuild it locally first to make sure that fixes it18:13:33
@emilazy:matrix.orgemily (cannot use --rebuild or --check, those break signature themselves) 18:13:40
@emilazy:matrix.orgemily(need to just build it without substituting on a machine without it in the store)18:13:49
@vcunat:matrix.orgvcunat It does seem to fix ./result/bin/autogen --help on this machine. 18:18:35
@vcunat:matrix.orgvcunat * It does seem to fix ./result-bin/bin/autogen --help on this machine. 18:19:21
@vcunat:matrix.orgvcunat OK, pushed as e0d2da7967a3. Thanks. 18:25:03
@vcunat:matrix.orgvcunatOh good, the rebuild seems to have trashed (almost?) no successful builds.19:03:29

@emilazy:matrix.orgemily Randy Eckenrode: wondering if dropping Darwin exclusion from FFmpeg's withVulkan works on KosmicKrisp… 17:26:51
@emilazy:matrix.orgemily(probably it works with MoltenVK, I didn't test)17:26:57
@reckenrode:matrix.orgRandy EckenrodeWhat does it do?17:27:48
@reckenrode:matrix.orgRandy EckenrodeIf it’s using Vulkan video extensions, those are not implemented on either.17:28:23
@emilazy:matrix.orgemilyno, there are Vulkan-accelerated filters etc.17:29:33
@emilazy:matrix.orgemilyI believe that's just compute stuff.17:29:44
@emilazy:matrix.orgemilymight be wrong though…17:29:51
@emilazy:matrix.orgemilybut I don't mean video decoding, yeah.17:30:07
@reckenrode:matrix.orgRandy EckenrodeAh, maybe. How do we know it doesn’t work? Test failures?17:30:07
@emilazy:matrix.orgemily

well, the proximate cause of me wondering this is

Option vf: 'bwdif_vulkan' isn't supported.
Error parsing option vf (option parameter could not be parsed)
Setting commandline option --vf=bwdif_vulkan=mode=1 failed.
17:30:46
@emilazy:matrix.orgemilyso I guess seeing if mpv can use the Vulkan-accelerated filters would be the test case :)17:31:15
@reckenrode:matrix.orgRandy EckenrodeI can try building it and see.17:31:32
@emilazy:matrix.orgemilyjust seemed odd that we use Vulkan for mpv but have it turned off in FFmpeg – but I guess it's from back before we used MoltenVK a lot.17:31:53
@reckenrode:matrix.orgRandy EckenrodeMy KosmicKrisp branch is also out there though, and it’s built on master, so the rebuilds should be pretty mild.17:32:34
@reckenrode:matrix.orgRandy EckenrodeI try to update it when new KosmicKrisp commits are merged into Mesa.17:33:51
@reckenrode:matrix.orgRandy EckenrodeDoes GCC 15 build on Darwin?17:53:56
