 # j`ey on deleting efi and Linux partitions from the gui in macos
 20:46 < j`ey> Glanzmann: I didnt figure it out at the diskutil cli, but I managed to do it from the GUI, I think you have to erase/reformat as APFS before you can delete the volumes
 10:53 < j`ey> Glanzmann: for your notes: < tpw_rules> you can delete a non-apfs partition with: diskutil eraseVolume free n disk0sX
+21:07 < tpw_rules> you can delete a non-apfs partition with: diskutil eraseVolume free n disk0sX
 
 08:54 < mixi> Glanzmann: the command you're looking for should be "dtc -I dtb -O dts /sys/firmware/fdt"
-08:57 < jannau> Glanzmann: dtc -I fs -O dts -o - /proc/devicetree

+# j`ey on hack to hookup lid close/open
+23:19 < j`ey> apple_smc_event_received in drivers/platform/apple/smc_core.c is a good place to start looking
+
+# kettenis on the same issue using existing infrastructure
+23:20 < kettenis> so the lid is hooked up to gP01
+23:24 < kettenis> looks like you could try hooking that up using gpio-keys-polled
+23:27 < Glanzmann> kettenis: So gpio-keys-polled would poll gP01 and send a key event and than I could use my window manager to do something when that key event is received?
+23:29 < kettenis> look at arch/arm/boot/dts/imx6q-novena.dts
+
+# How to subscribe to smc events
+23:45 < j`ey> Glanzmann: if youre still interested in looking: drivers/power/supply/macsmc_power.c apple_smc_register_notifier(power->smc, &power->nb);
+23:46 < j`ey> so this driver gets called, when an SMC notification happens. looks like all registered handlers would be called and its up to the callback to figure out if it needs to do something
+
+# More background
+23:54 < kettenis> if the interrupts are hooked up correctly for thise SMC gpios, gpio-keys instead of gpio-keys-polled should work
+23:54 < j`ey> no irq_chip in the current driver
+
+17:34 <marcan> the image as built will have a real grub config with static UUIDs
+17:35 <marcan> well, a systemd early unit but yes

+16:00 < Glanzmann> So applying a new uuid to the rootfs needs to be done in the initrd.
