gunnarxrajm, is CTtpollard not around today?08:57
gunnarx...so used to him being here :)08:57
rajmhe's just arrived gunnarx08:58

gunnarxrajm, CTtpollard: Just FYI I have set aside a few hours now for working on some build stuff and triggering a bunch of builds - let me know if you need the Go resources free for other things09:01
CTtpollardgunnarx: should be fine today on my end09:01
gunnarxAlso, I am bouncing around a bunch of ideas on how to structure  pipelines which might overlap the new release pipeline somewhat, so if you're working on that today let's sync up so I don't step on anyone's toes09:02
CTtpollardI have no plans today to touch go.cd :)09:04
gunnarxOh good...I'm not a terrible dancer or anything, but injuring someone's toes has happened once or twice, so just making sure. :)09:04
gunnarxthen I'll just report on my progress later on09:04
CTtpollardradiofree: rebuilt with linux 4.6.1, still has the mouse issue09:26
radiofreedo you have the same problem with the virtio driver?09:26
radiofreedoes the weston log have anything about input devices?09:27
CTtpollardwill output it again (using -vga std)09:27
kbroulikis anyone of you at QtCon/Akademy? perhaps we could have a talk/BoF about plasma on genivi there09:27
radiofreehow are you compiling weston?09:30
CTtpollardradiofree: interestingly it's not listing the mouse this time, only the laptops touchpad http://paste.baserock.org/onohiqekem09:30
radiofreeand the mouse works with --backend=fbdev-backend.so ?09:32
CTtpollarddid yesterday, will just double check with this kernel09:32
radiofree(it did work?)09:33
CTtpollardradiofree: yep, just rebooted with fbdev and the cursor is working, and the gfx is smoother than it originally was09:34
radiofreelooking at the code, both the fbdev and drm backends initialise input via udev_input_init09:35
*** ashwasimha_ has joined #automotive09:35
radiofreehowever fbdev just reads "seat", drm reads "param->seat"09:35
CTtpollardhttp://paste.baserock.org/nigoyahuzu09:35
radiofree 232 static const char default_seat[] = "seat0";09:36
radiofreewhich is the same in fbdev...09:36
CTtpollard:S09:37
CTtpollardkbroulik: I believe it's on at the same time as the genivi AMM in SF?09:39
radiofreedrmModeSetCursor is failing09:39
kbroulikCTtpollard: QtCon is September 1 through 809:39
radiofreeCTtpollard: can you try with -vga qxl09:40
CTtpollardradiofree: with weston back on drm?09:40
radiofreenot qxl, that's not enabled09:40
radiofreetry -vga cirrus09:40
radiofreeyes, weston on drm09:40
CTtpollardradiofree: http://paste.baserock.org/zoqunitero09:44
radiofreewonderfulo09:44
radiofreeand finally -vga virtio09:44
CTtpollardsame as before, unknown vga type09:45
radiofreeyou need to update your qemu...09:46
radiofreeCTtpollard: can you put the image somewhere and tell me how to boot it, i'll take a look09:49
CTtpollardradiofree: sure will ping you09:50
*** intprka has joined #automotive09:50
*** theevrm has joined #automotive09:56
radiofreeCTtpollard: the mouse is working, there's just no cursor showing up10:03
radiofreeso it's some issue with setting the cursor plane10:03
radiofree(this is with virtio)10:03
*** theevrm has left #automotive10:04
CTtpollardradiofree: what's most likely to be the culprit for that?10:04
radiofreemight be a problem in weston10:14
CTtpollardif there's anything else that I could recompile weston with I'll give it a shot10:15
radiofreecan you try with desktop-shell, and if that doesn't work try with weston 1.1010:18
CTtpollardyes, 1.10 though I'll probably have to drop back to an older GDP version, but I suppose it will still serve the same purpose10:21
*** khem has quit IRC10:24
*** theevrm has joined #automotive10:28
*** khem has joined #automotive10:28
CTtpollardradiofree: the next weston version I can drop back to would be 1.9, and kernel-wise it would be 4.110:59
radiofreeshould still be ok for bochs10:59
*** jeremiah has joined #automotive11:09
CTtpollardok setting that off, might be a while11:09
CTtpollardand this baseline is untested with 4.1, so might run in to other issues (explicitly sets 3.14)11:13
*** theevrm has quit IRC11:46
CTtpollardradiofree: no gallium virgl in mesa 10.6.3, any alternatives I should try?12:33
CTtpollarddropped virgl, seems to be reverting to whatever the standard gallium drivers are12:43
CTtpollardswrast, r60012:44
CTtpollardjeremiah: I'm on the dev list now, Philippe approved me earlier12:47
CTtpollardI don't know that the past issues were12:48
radiofreeCTtpollard: gallium swrast will be needed13:13
radiofreevirgl is very new, that won't be there13:14
CTtpollardradiofree: yup gone with swrast, in the midst of compiling webkit and rust so will have to wait for the result13:16
JEEBkbroulik: QtCon will be fun this year, OSS multimedia is IIRC in the same place :)13:44
kbroulikJEEB: indeed, Qt, KDE, VLC, FSFE... will be huge13:45
* JEEB is contributing to OSS multimedia so will be around for that13:45
*** kooltux_ has joined #automotive13:49
CTtpollardradiofree: same problem, although under drm it actually see's the mouse unlike on 1.11 http://paste.baserock.org/oluvoyixab14:40
CTtpollardleon-anavi: thanks for the ticket report :)14:49
CTtpollardnow hopefully we can solve the virtual keyboard issue to make it more of a viable peripheral14:50
*** ashwasimha_ has quit IRC14:52
leon-anaviCTtpollard, you are welcome :) I have just update an old mail thread that was bugging me for a while :)14:52
leon-anaviFinally the touchscreen is working and Roland should be happy ;) :) :)14:53
CTtpollardleon-anavi: heh, it's nice to see anholt's work being upstreamed and then used by a project so quickly I think14:53
leon-anaviabsolutely :)14:54
leon-anavigreat work :)14:54
leon-anavivery important milestone for the community14:54
leon-anavialthough raspberry pi is not that important for the industry it is nice to have it as an option for quick prototyping14:54
leon-anavifurthermore so many devs already have it and the touchscreen. Now they can contribute more to the project :)14:55
*** jlrmagnus has joined #automotive14:56
CTtpollard:)14:58
radiofreeseems to work if you launch it with just "weston"15:03
radiofree(from tty0)15:03
CTtpollardinto desktop shell?15:03
radiofreeyes15:04
radiofreenot with ivi-shell though...15:05
radiofreeworks (ivi-shell) if i launch it via tty0, not over serial15:06
leon-anaviCTtpollard, the virtual keyboard is not hardware specific, right?15:06
CTtpollardleon-anavi: doesn't seem to be, the faytech and raspi screen both have the issue15:07
radiofreeactually serial seems fine15:07
radiofreeyou have to move the mouse about a bit then it appears15:07
leon-anaviCTtpollard, what if GDP is booted with mouse and HDMI monitor without touchscreen?15:08
CTtpollardradiofree: odd, it's appears for me but it flicks everywhere15:08
radiofreecomes up when you click qemu here15:08
CTtpollardleon-anavi: no virtual keyboard either, but currently path is set to null in weston.ini because at one point in time the virtual keyboard came up constantly, much like that OSB blog reported15:09
CTtpollard*OSG15:09
radiofreeCTtpollard: and it works with weston launch15:09
radiofreei just have to click it....15:09
radiofreeprobably a qemu issue then? (upgrade that)15:09
CTtpollardis this the 1.9 or 1.11 image?15:10
CTtpollardand -std?15:10
leon-anaviCTtpollard, ok, it will be interesting to see this15:10
radiofree-vga std15:10
leon-anaviI will find some spare time to reproduce the bug in the coming days/weeks.15:10
radiofreei get nothing with -vga virtio though15:11
radiofreeno mouse that is, graphics work15:11
CTtpollardbah, got the latest qemu-kvm in apt15:13
radiofreeCTtpollard: i have the same issue with virgl/mouse cursor in a baserock image as well15:16
* radiofree reminds people this virtio gpu stuff is pretty new15:16
radiofreehowever bochs works fine (like this gdp)15:16
radiofreei should not i've completely buggered up mesa on this system trying to upgrade my qemu to something that supports virtio-gpu properly...15:17
radiofrees/not/note15:17
CTtpollardouch15:17
radiofreei did that months ago though15:17
* radiofree really should upgrade to fedora 2415:17
gunnarxFYI: go.genivi.org is down for maintenance - expect to be up in 30min again15:18
CTtpollardI could send a PR to switch to drm, and change the instructions for booting with std, but then users of 14.04 would run into the same issues I'm having. So I don't know what the best course of action is15:19
CTtpollard(baring in mind we still recommend 14.04 for bitbake built hosts)15:19
CTtpollard*bearing15:19
radiofreetell people not to use an antiquated version of qemu?15:20
radiofreeat a minimum the mesa change is useful for the llvmpipe stuff15:20
radiofreemaybe you could use a script to launch weston15:20
radiofreeif drm available use the drm-backend, else fbdev15:21
radiofreewhat version of qemu are you using?15:22
radiofreeqemu-kvm --version15:22
CTtpollard2.2.015:22
rajmI've got version 2.5.50 (built from git yesterday and it appears even stickier15:24
*** kooltux_ has quit IRC15:25
gunnarxdefine stickier :)15:25
gunnarxslower?15:25
*** kooltux_ has joined #automotive15:25
rajmlike wading through glue! I have to will the mouse across the window sometimes15:26
CTtpollardrajm: if I point you to the images me and radiofree are testing could you see hoe they act under 2.5.50 ?15:26
CTtpollard*how15:26
rajmcertainly!15:26
CTtpollardthanks15:28
radiofreerajm: use the image CTtpollard built15:30
radiofreetry with -vga std and -vga virtio15:30
radiofreerajm: you have to compile qemu with opengl and gtk support for virtio to "properly" work15:32
radiofreeit'll work without that, however it won't use your hardware (falls back to software rendering)15:32
radiofreewhich should still be much faster now15:32
radiofreeand i think there's some userspace host component as well...15:33
radiofreerajm: https://virgil3d.github.io/15:33
radiofreevirglrenderer15:33
radiofreebut that should be significantly faster since you'll be using the gpu on your host15:34
CTtpollardwhat does std default to using driver wise?15:34
radiofreeBOCHS, software15:37
radiofreebochs is just some emulated drm gpu in the guest15:37
*** jeremiah has quit IRC15:39
CTtpollardso I could drop the all but the bochs kernel module in that case, and virtgl in mesa15:39
CTtpollardkeeping swrast15:39
radiofreewell, keep bochs and the virtio15:40
radiofreethey'll both use drm, and the kernel will detect which one to use15:40
radiofreerecommend -vga std, however if someone has the setup -vga virito is nice to have as well15:40
radiofreethey won't conflict with each other15:40
CTtpollardrajm's kvm seems to display the same issue as mine with drm15:45
CTtpollardand fbdev shows the same performance increase15:45
*** AlisonChaiken has quit IRC15:46
CTtpollardradiofree: the selecting backend sounds like a viable path, but the drm is available which would be the problem15:50
*** rajm has quit IRC15:51
radiofreeCTtpollard: check /sys/class/drm for any card* ?15:51
CTtpollardradiofree: what I mean is drm is *there*, but has the cursor error so I don't know how to account for that15:52
CTtpollardother than restarting weston with fbdev if that error was to occur15:53
radiofreecursor should work fine with bochs, solution: upgrade qemu15:53
CTtpollard:P15:53
CTtpollardpart of the reason for the qemu image is for user who don't wish to build the image, I'm not sure having a dependency on manually upgrading their distros qemu goes with that15:54
