Hi
I have been looking at getting pigpio into Debian.
Time for an update
Upstream accepted a pull request to give the libraries proper sonames.
I then added raspberry pi detection code.
I then decided to test if pigpio could be used on a Debian arm64 system. The
first thing I ran into was a bunch of issues about assuming that pointers were
four bytes in size causing a bunch of scary compiler warnings. I worked through
those warnings. fixing them.
I then had to expand the raspberry pi detection code, 64-bit kernels
unfortunately don't put the same information in cpuinfo as 32-bit ones do.
I have just submitted a pull request for the above issues.
However I then ran into a more significant issue. Pigpio relies heavilly on DMA
and to set this up it relies on a kernel driver that has not been upstreamed.
So pigpio is not compatible with Debian kernels.
I would therefore propose for now packaging only the client components of
pigpio in Debian. What do others think?
