| T42 | <HengYeDev> @spiiroin it does not crash, but minimer causes kernek crash if mce start too early | 00:09 |
|---|---|---|
| T42 | <HengYeDev> @elros34 Maybe i should just add a sleep in the systemd unit of mce? I will try the start hwcomposer early as well | 00:32 |
| T42 | <elros34> IMHO spiiroin's patch looks better then any unreliable delay hacks (assuming it will help) | 00:35 |
| T42 | <HengYeDev> @elros34 Wont it cause the power management of screen dimming to break? | 00:36 |
| T42 | <elros34> I think not necessary, there is still display on/off handle in qpa-hwcomposer but I am not an expert | 00:37 |
| T42 | <ceptoreceptor> What tablet is this? (re @HengYeDev: ) | 01:46 |
| HengYe[m] | samsung galaxy tab s6 lite | 01:47 |
| spiiroin | mce pretty much needs to start when it is started now -> sleeps, reordering of service starts, etc should be avoided | 03:49 |
| spiiroin | those fbdev ioctls for display power that mce does are sort of legacy architecture wart... | 03:50 |
| spiiroin | in new devices it should go through like @elros34 says: through hwcomposer plugin | 03:51 |
| spiiroin | currently what might happen is that both mce and compositor do it - in most cases it does not matter, but apparently you bumped into situation where it causes problems | 03:52 |
| spiiroin | if that patch does help, then I could make it into something that can be selected via (device specific) config options | 03:54 |
| T42 | <edp_17> I've unmasked some services but when trying to start them, they say cannot be started as they are masked. I thought removing the masked link from /etc/systemd/user or system is enough and then the services can be started manually or is this required a reboot? | 10:54 |
| spiiroin | @edp_17, have you've tried "systemctl unmask UNIT" instead of dealing with symlinks manually? | 11:05 |
| T42 | <edp_17> spiiroin: Nope because I wasn't avare of this. However, now I did this way but systemctl-user status UNIT still says: Loaded: masked | 11:07 |
| T42 | <edp_17> I guess should remove the symlink from /etc/systemd/user/ 🤔 | 11:08 |
| T42 | <edp_17> Yep, I needed to manually unlink the symlink. Now it is Loaded: loaded. Although, Active: inactivve (dead) | 11:10 |
| T42 | <elros34> systemctl-user unmask <service> should do this for you and change systemd state | 11:10 |
| T42 | <edp_17> Well, it didn't do that. I ran this but the symlink has remained. I had to manually unlink. | 11:13 |
| T42 | <elros34> probably because you added symlink to /etc/systemd/user but systemctl-user mask user user writable ~/.config/systemd/user/ | 11:16 |
| T42 | <elros34> use user writable* | 11:16 |
| T42 | <edp_17> Yes, I've added the symlink into /etc/systemd/user because I wasn't aware of the systemctl-user mask command. I'll remember to using it from now on. | 11:18 |
| T42 | <edp_17> More info on the mistrerious reboot. (This time it is on the N7000). The device starts with all those four services masked. Then I could unmask/start them one by one without causing the reboot. However, when I tap on the Phone icon, the device reboots. I think this is because the voicecall-ui-prestart.service uses sailjail. | 11:28 |
| T42 | <HengYeDev> @spiiroin @elros34 To build mce do i use the platform sdk or the regular app-development sfdk? | 22:45 |
| T42 | <elros34> platform sdk, just clone sources, apply patch and run build_packages.sh -b <path to source> | 22:48 |
| T42 | <HengYeDev> @elros34 I get dependency errors: https://gist.github.com/HengYeDev/0165931117917679dcc15a603c9b70ca | 22:50 |
| T42 | <HengYeDev> zypper in does not get them installed as No provider found | 22:50 |
| T42 | <elros34> what is mce*? use <path to directory with mce source> | 22:52 |
| T42 | <elros34> in latest lines you see where to search full log | 22:53 |
| T42 | <HengYeDev> it is the path relative to hadk (re @elros34: what is mce*? use <p...) | 22:55 |
| T42 | <HengYeDev> i put it in the hadk dir | 22:56 |
| T42 | <elros34> ok then, usually all sources are in hybris/mw/. | 22:56 |
| T42 | <HengYeDev> @elros34 ok i moved it there for consistency. full log: https://gist.github.com/HengYeDev/609c1de75e8142a62ab2542b4617de82 | 22:58 |
| T42 | <elros34> not sure but I suggest to always build same version as used in your | 23:04 |
| T42 | <elros34> current release | 23:05 |
