This diff is now in snapshots, so instead of applying the diff and
build your own kernel, you can just upgrade to the latest snapshot.

Thanks,

the build system should not be discovering things!

Suspend/Resume on modern Intel laptop platforms

2021-09-15 Thread Mark Kettenis
The diff below is a preliminary diff to fix a suspend/resume issue on
recent Thinkpads.  This needs testing on a wider range of laptops to
make sure it doesn't break things.  The diff also puts some
information in dmesg that will help me improve things in the future.

So, if you have a laptop where pchgpio(4) attaches *and* supports S3
suspen/resume, please apply this diff, do a suspend/resume cycle and
send me a dmesg collected after that suspend/resume cycle.

Thanks,

Mark

I've just committed a fix to xdpyinfo build system to explicitely
disable dmx support in that case.

libdmx.so has been removed recently. From
xenocara/app/xdpyinfo/configure, dmx library could be detected as
build time.

I suppose the host used to build the snapshots still has old dmx
library in path, and the build of xdpyinfo detected it and link to it,
whereas the library isn't in sets anymore.

Thanks for the report.
