Beginners • What are all the available options for /boot/config.txt ?

Hi,

I'm in the final stage of compiling my Linux kernel for my raspberry pi 4
(btw thanks for those how already helped me ! )

I'm reading the arch/arm64/boot/dts/overlays/README that describe how to use the Device Tree overlays

it's weird because in my previous config.txt ( that was part of a full .img for Raspberry ) is can see I don't find anymention of hdmi_safe in the README nor on https://www.raspberrypi.com/documentati ... g_txt.html
maybe it's no longer in use ?
or if it is, is there somewhere a list with all the "options" ?

--
and for the led:

I can see the act_led_trigger and we can read

Choose which activity the LED tracks.
Use "heartbeat" for a nice load indicator.
(default "mmc")

but, is there other options ? or is it only ["heartbeat", "mmc"] ?

and how should it be encoded ?
act_led_trigger=mmc
or
act_led_trigger="mmc"

And finally whats does the heartbeat just a constant flashing ?

Thanks.
