| wesam | does it matter where you add your own layer in the bblayer.conf file | 16:27 |
| CTtpollard | no, but layer priority values can matter | 16:29 |
| *** kbroulik has quit IRC | 16:30 | |
| wesam | oh really | 16:32 |
| wesam | what should my layer priority be | 16:32 |
| wesam | or is there any documentation on what number i should put | 16:32 |
| wesam | my script isnt that important at all | 16:32 |
| CTtpollard | it's not particularly important unless there are recipe conflicts | 16:40 |
| CTtpollard | if your package does not exist in other layers it's fine | 16:41 |

| mranostay | anyone know if Eric Anholt is on IRC? | 20:17 |

| dl9pf | mranostay: let's bump our allocs down to 256 and update. we'll have to deal with the fallout | 20:34 |
| mranostay | ok | 20:34 |
| dl9pf | hopefully the newer kernels fix these issues | 20:34 |
| leon-anavi | I have some trouble with VC4 drivers why working on the wayland/weston upgrade for AGL and morty... | 20:44 |
| leon-anavi | right now I have just checkout older version of meta-raspberrypi but still from branch morty | 20:45 |
| *** claneys has quit IRC | 20:50 | |
| khem | mranostay: what cma limits do you use | 21:03 |
| dl9pf | khem: we had to bump it quite high for wayland to work with the surfaces created ... lets see | 21:06 |
| dl9pf | 640 | 21:06 |
| dl9pf | o_O | 21:06 |
| khem | no you dont have that much memory | 21:09 |
| dl9pf | the kernel probably skip'ed the option then, now I wonder how it worked ;) | 21:09 |
| dl9pf | let me grab a dmesg ... | 21:09 |
| khem | dtoverlay=vc4-kms-v3d,cma-256 | 21:10 |
| khem | in boot/config.txt | 21:10 |
| khem | is max | 21:12 |
| dl9pf | https://paste.debian.net/917332/ | 21:12 |
| khem | We are able to play 1080p with this setting | 21:12 |
| khem | why is this different for AGL | 21:12 |
| dl9pf | hmm ... cma=256@256 ... hmm | 21:12 |
| dl9pf | but why did it say cma: Reserved 476 MiB at 0x1f000000 | 21:12 |
| khem | what does your config.txt look like | 21:12 |
| dl9pf | vc_mem.mem_base=0x3dc00000 vc_mem.mem_size=0x3f000000 | 21:12 |
| dl9pf | dtoverlay=vc4-kms-v3d-overlay,cma-256 | 21:13 |
| khem | btw. I met eric recently and he said upstream 4.10 should work well for rpi3 so one of these days I will add that recipe | 21:13 |
| JEEB | rpi3 stuff did IIRC land @ 4.10 | 21:13 |
| khem | we can get away from raspian kernel | 21:13 |
| dl9pf | we just bump'ed it b/c wayland was spitting out allocation errors with multiple surfaces (probably no reclaim) | 21:14 |
| dl9pf | this might be better in later kernels anyway | 21:14 |
| khem | dl9pf: what do you have form gpu_mem_1024 | 21:15 |
| khem | dl9pf: you need a light version of compositor | 21:15 |

| *** hyde has quit IRC | 21:36 | |
| dl9pf | nop, ... let me find-out where this is ... | 21:36 |
| dl9pf | I don't get it. GPU_MEM can be up to 944 - right ? | 21:39 |
| dl9pf | https://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/tree/README?id=68b18fa80e90e3a3ca2b7b684f4664bf0a4a1635#n93 | 21:39 |
| dl9pf | so there should be no prob to set it to 640 | 21:40 |
| dl9pf | cma is a different topic then ... | 21:40 |
| *** jlrmagnus has quit IRC | 22:02 | |

| leon-anavi | so I made some good progress with Wayland/Weston 1.11 in AGL for Raspberry Pi 3. | 22:05 |
| leon-anavi | Details are available here: https://jira.automotivelinux.org/browse/SPEC-411?focusedCommentId=12203&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12203 | 22:06 |
| leon-anavi | there are two major remarks: 1. the latest 4.4 kernel from meta-raspberrypi fails to boot therefore I am using a bit older version of the layer (still from branch morty) | 22:06 |
| leon-anavi | 2. The HomeScreen application doesn't work and I have no idea how to debug it. | 22:06 |
| leon-anavi | the status that I published is work in progress and I still have a lot of things to improve before submitting it to Gerrit :) | 22:07 |
| khem | 4.9 is now stable even for linux-raspberrypi | 22:08 |
| khem | so you should switch to that | 22:08 |
| leon-anavi | khem, ERROR: linux-raspberrypi-1_4.9.10+gitAUTOINC+095c4480e1-r0 do_fetch: Fetcher failure: Unable to find revision 095c4480e1f623bdc8a221a171ef13b2223706b1 in branch rpi-4.9.y even from upstream | 22:08 |
| leon-anavi | I got this error earlier today | 22:08 |

| leon-anavi | I am ok with 4.4.43 for the moment. Btw I think mranostay found the issue with the latest 4.4 kernel in meta-raspberrypi (branch morty) | 22:17 |
| mranostay | well 4.9.13 but probably was backported to 4.4.x | 22:18 |
