Tartarus | dl9pf: ping | 12:38 |
*** waltminer has joined #automotive | 12:54 | |
dl9pf | pong | 13:10 |
dl9pf | Tartarus: pong | 13:10 |
Tartarus | dl9pf: Hey, so, compressed VM images | 13:11 |
Tartarus | How do we want to handle needing to make changes to a core bbclass? :) | 13:11 |
dl9pf | there is no appends for bbclasses ... so we'd have to put it into meta-agl or meta-agl-bsp which has a higher prio | 13:15 |
dl9pf | https://git.automotivelinux.org/AGL/meta-agl/tree/meta-agl/classes | 13:15 |
dl9pf | we did that once already to backport a fix for useradd.bbclass | 13:16 |
dl9pf | see commit 418cd42c9c18b649f8c839849108f7a309bdc8fa in meta-agl ... so throw a copy in meta-agl/classes | 13:18 |
Tartarus | dl9pf: OK, copy in and then next commit does changes? Or just all in one commit? | 13:20 |
dl9pf | all in one | 13:20 |
Tartarus | OK, will do, thanks | 13:21 |
* mranostay spots Tartarus.. and runs in fear | 13:21 | |
Tartarus | dl9pf: How worried are you about the case of both vmdk and vmdk.xz being desired? | 13:21 |
*** jobol has quit IRC | 13:21 | |
Tartarus | ah, wait, yay, I found the right bit of bb magic | 13:22 |
dl9pf | tbh if the user (= /me) requests vmdk.xz there should be only vmdk.xz . No stray extra files. | 13:22 |
dl9pf | if he requests vmdk , then there should be vmdk . | 13:22 |
Tartarus | dl9pf: Right. This leads nicely to the next question I had, how much do we want to push on this upstream? | 13:23 |
dl9pf | I'm not in favour of build products laying around in the deploy/images/<MACHINE>/ | 13:23 |
Tartarus | The VM image handling stuff is different from normal images, even complex normal images like ubi/ubifs | 13:23 |
Tartarus | dl9pf: (Aside, if 'foo' in d.getVar('BAR', d): will catch foobar in BAR, but bb.utils.contains will get this right, so we're good now) | 13:24 |
dl9pf | Tartarus: as much as possible ... i know e.g. the intel-corei7 image creation is doing ext4 -> hddimg -> iso / live -> wic and all ends up in the output dir ... | 13:24 |
dl9pf | so we'll need to see how things interact | 13:25 |
Tartarus | dl9pf: OK. I have a feeling RP won't like this, since we cannot reuse the current COMPRESSIONCMD stuff | 13:25 |
dl9pf | ok, let's see | 13:25 |
Tartarus | I'll get an RFC out sometime shortly then and see what RP says, and then move from there | 13:26 |
Tartarus | (RFC for upstream, that is) | 13:26 |
dl9pf | yep | 13:26 |
*** jobol has joined #automotive | 13:28 | |
Tartarus | dl9pf: Should I pick-up and re-use https://gerrit.automotivelinux.org/gerrit/#/c/9029 for the change-id? | 13:29 |
Tartarus | Been a bit since I've had to do gerrit stuff | 13:29 |
Tartarus | We could move that one to abandonded and I'll add vmdk.xz and then qemux86* using that via AGL_EXTRA_IMAGE_TYPES | 13:29 |
*** jobol has quit IRC | 13:32 | |
dl9pf | ok | 13:38 |
*** msisov has joined #automotive | 13:41 | |
Tartarus | dl9pf: While I'm in here, vmdk.xz + qcow2, vmdk.xz + qcow2.xz, or just vmdk.xz ? | 13:46 |
*** zmc has quit IRC | 13:46 | |
Tartarus | I know mdp wrote the JIRA for vmdk + qcow2 | 13:46 |
Tartarus | and "everything" supports vmdk | 13:46 |
*** zmc has joined #automotive | 13:46 | |
dl9pf | vmdk.xz by default | 13:46 |
*** bjornw has joined #automotive | 13:47 | |
dl9pf | we're doing ext4.xz which is perfectly fine for qemu | 13:47 |
dl9pf | we don't need qcow2 | 13:47 |
Tartarus | Drop qcow2? OK | 13:47 |
dl9pf | yes | 13:48 |
mdp | vmdk is fine for qemu too | 13:58 |
mdp | qcow2 is most efficient, but since we've opted to optimize for disk space..the user can choose to build that on their own. | 13:59 |
mdp | Tartarus: yeah, that title is months old ;) | 14:00 |
*** toscalix has quit IRC | 14:04 | |
*** msisov has quit IRC | 14:07 | |
*** fredw has joined #automotive | 14:08 | |
mranostay | mdp: is there much difference in VM formats? | 14:13 |
*** msisov has joined #automotive | 14:21 | |
*** msisov has quit IRC | 14:30 | |
* Tartarus kicks gerrit | 14:32 | |
CTtpollard | Tartarus gets absorbed into the java | 14:34 |
Tartarus | dl9pf: I made gerrit a little mad since I couldn't re-use the changeid on https://gerrit.automotivelinux.org/gerrit/#/c/9031/2 | 14:34 |
* dl9pf looks | 14:36 | |
*** maximsalnikov has quit IRC | 14:39 | |
*** bjornw has quit IRC | 14:44 | |
*** msisov has joined #automotive | 14:45 | |
Tartarus | dl9pf: OK, nvermind, mdp corrected me | 14:46 |
Tartarus | 10273 is abandoned, the other 2 are good to go, generally speaking | 14:46 |
Tartarus | preparing to RFC vmdk.xz upstream now and see what happens there | 14:46 |
mdp | mranostay: yes..it's a bit complicated. from a simple pov one can put a raw or vmdk on anything. | 14:48 |
*** halfline has quit IRC | 14:48 | |
mdp | however, you start to get into practical concerns with raw disks in that they are a fixed full size..whereas formats like qcow2 can grow as data is added..which is why people tend to prefer a special format | 14:48 |
mdp | further, why would somebody choose to use qcow2 on qemu on linux? well, it's easily mountable with qemu-nbd to go manipulate it... | 14:49 |
mdp | as far as just traditional block i/o performance, I don't see any appreciable difference though supposedly qcow2 is still faster than vmdk in qemu as the latter came in much later. | 14:50 |
mdp | tbh, AGL UI latency is a generic issue and we don't even have any serious graphics pressure to see any noticeable performance difference even with drm backend disabled. | 14:51 |
mdp | it's not like any of the apps are doing animated icons or video playback | 14:52 |
mdp | it's a very static set of layers with minimal widget interaction | 14:52 |
mdp | mranostay: so that's my 2 cents | 14:52 |
mdp | perhaps a bit more | 14:53 |
*** msisov has quit IRC | 14:55 | |
*** fredw has quit IRC | 14:56 | |
fury | I want animated icons and video playback! :D | 14:56 |
* fury ducks | 14:56 | |
fury | well, at least streaming video from e.g. a camera that's spitting out h.264 | 14:56 |
mdp | "patches welcome" | 14:56 |
fury | that'd be cool | 14:57 |
mdp | fury, you can have it all! | 14:57 |
fury | rollin in the deeeeeeeep! | 14:57 |
mdp | fury, as we say a lot at work, "It's just more software, we can do anything." | 14:57 |
mdp | "...with enough budget." | 14:57 |
fury | famous last words? :D | 14:57 |
fury | yeah lol | 14:57 |
fury | those magic words | 14:58 |
fury | show me the moneeeeey! | 14:58 |

Tartarus | Still sorting out all the details on how to do this in a better way for upstream | 16:08 |
