--iFNHVD+8cDNfhebL Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi Emmanuel, I notice you indicated that there is thermal support for the H6 on https://wiki.freebsd.org/arm/Allwinner. I've just started experimenting with a PINE H64 and noticed the board didn't report any temperature data. Looking through the head code, the doesn't seem to be any support for sun50i-h6-ths. Do you have the code in a branch somewhere? Before I noticed the wiki page, I started looking at implementing the code myself. I had expected it would just be a matter of replicating the H5 code and tweaking the constants but, reading the Thermal Sensor Controller section of the H6 manual, it looks like the H6 controller is very different to the H5 controller: The registers are at different offsets and laid out differently, so it's not compatible with (eg) sys/arm/allwinner/aw_thermal.c:aw_thermal_init(), which is a PITA. Have I missed something? --=20 Peter Jeremy --iFNHVD+8cDNfhebL Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE7rKYbDBnHnTmXCJ+FqWXoOSiCzQFAmIUsAxfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEVF QjI5ODZDMzA2NzFFNzRFNjVDMjI3RTE2QTU5N0EwRTRBMjBCMzQACgkQFqWXoOSi CzQzYRAAm8cl+UkCEgBokimJvbzroA436/BPnIVBVmE++LRG2gU9/Udm/WpUBD0d qM5M816EMXDGNDEDOgTbR/60wEEVGE2jHvFnyWSfKIGnYloKdyRZ1+d2X7KEHyt/ DXXaXpFm9uTLUg+LS1BwW+b9D/h40lwxnk7KB/1YcX2WmPvEPXTVHlAJWoCigBq4 lRAzvzYzsbL54Z1JCNqceQZuo5Mf+z1kwG/I22E7QoP++JmAU1t7luy0F6qlVoCj WpF3hpvtAxI2PxWhQRAaSpp+Vjhf3//irryns1brCQ/wgmLMB/aDZxBLHQPbITdR ROVQooDJ8+XHAo/A7bbOmWff9CvybC/jZK9AcAAdDUGczJselzQIMnrnxBiYfLAk NdiKgaQ9rlhlqQZTGKP+9u0q7qEfOhvsnLwcI6ZgbdBN3h+NUTi/6zMq8QVwG8if Vl6M6j4bh3ycBSwTow9qiASMKAt43S5OGmn+OoluKsjsANDjO9fr+mk9GnDoKOxc S+4gvIjKK5nUPGcXTM8mp98cvjDWXU9if9uJDNrTjBjWrVxvW3vrUt7XYWAwgKfc YUevPHDMf/2u/gnE8uvNBVrgHJlVwKigmfupBNUGHqdiw9zew4oj307oMLpY3KNq unHTu2SwnA+N0kRGlxsv0joAkTN5Ep1NX/uuGh8Rdh84T82nayM= =pXMT -----END PGP SIGNATURE----- --iFNHVD+8cDNfhebL--
