After writing
these notes (in particular, the
section about interrupts), I've noticed we didn't document what all these interrupts are used for. This info is interesting for emulation and understanding how Canon code works; they are not used directly in ML code.
So, here's my first attempt to list all the interrupts we know about. Sources of info:
-
startup-logs or
emulation logs with register_interrupt calls enabled (some have names in Canon code):
grep --text -nro " register_interrupt(.*)" startup-logs/ tests/*/gdb.log | grep -o register_interrupt.*
- interrupts declared in QEMU,
model_list.ccat qemu-2.5.0/hw/eos/model_list.c | grep -o "\..*interrupt.*=.*,"
- interrupts scattered in QEMU source: eos_trigger_int (either hardcoded IDs or arrays)
FILES=$(cat qemu-2.5.0/hw/eos/Makefile.objs | grep -E "eos/\w+.o" | grep -oE "\w+.o" | cut -d . -f 1 | sed -e 's/$/.c/' | sed -e 's!^!qemu-2.5.0/hw/eos/!')
cat $FILES | grep "eos_trigger_int\|^\w.*(" | grep -B 1 eos_trigger_int
cat $FILES | grep -zoE " [a-zA-Z_]*interrupt[a-zA-Z]*\[[^[]*] = {[^{]*}" | tr "\\n" " " | tr "\\0" "\\n"

TODO:
- group by camera generation, DIGIC version etc
- other sources of info (such as strings present in the interrupt handling function, or other notes about them)
- brute-force interrupts (trigger manually) and see what the firmware is trying to do
- auto-build the above list on Jenkins (so it will be always up to date, at least with QEMU sources)
