| nightishaman | mal: https://pastebin.com/kdWV8rtr the issue is happening also with the lineageos boot.img and vendor_kernel_boot.img. I might test tomorrow what the kernel prints by booting full LineageOS android instead of hybris init, but I think it has to do with the issue that pKVM can't load the protected modules | 02:29 |
|---|---|---|
| T42 | <nightishaman> It’s either modprobe is broken or something in the kernel is broken. I will enable a higher loglevel tomorrow. Also Claude suggested disabling pKVM | 02:44 |
| nightishaman | mal: so i conclude, the recovery successfully loads it, with linageos kernel and vendor kernel boot it is broken, so the only angle is that the init_boot image has something that breaks the early load | 20:20 |
| nightishaman | and unless that is fixed or i disable pkvm, it wont boot | 20:20 |
| nightishaman | i didnt test that yet | 20:21 |
| mal | check what the recovery does? | 20:35 |
| mal | maybe it disables watchdog or something | 20:35 |
| mal | check the .rc files at least | 20:35 |
| mal | in recovery ramdisks | 20:35 |
| nightishaman | the issue is certainly due to the failed pKVM load, pKVM loads even before init runs and calls modprobe to load the module. In hybris init_boot it fails with error code 11(EAGAIN) and the modules dont load, in android recovery it does load and the EL2 code is run, eliminating the issue | 20:36 |
| nightishaman | when the modules are not run in the pKVM context, they fail to load and the kernel panic happens because one variable can only be set one time and the module tries to register again and set that only once variable and fails. the memory of the variable is cleared because the first module is unloaded and the pointer points to other memory | 20:37 |
| nightishaman | just a question, where is modprobe on the hybris init_boot? | 20:38 |
| nightishaman | if u know that? | 20:38 |
| nightishaman | i think i found the issue | 20:42 |
| nightishaman | there is no modprobe on hybris-init_boot | 20:42 |
| nightishaman | stock android has it in init_boot at /system/bin/modprobe | 20:42 |
| nightishaman | which is where CONFIG_MODPROBE_PATH in kernel points to | 20:42 |
| nightishaman | mal: where does the modprobe come from that the init-script uses? | 20:44 |
| mal | it's prebuilt https://github.com/mer-hybris/android_external_busybox_prebuilt | 20:46 |
| mal | modprobe is in busybox | 20:46 |
| T42 | <nightishaman> hmm, pKVM can’t call that probably | 20:47 |
