Can't write to file about amdtweak HOT 6 CLOSED

Sorry for inconvenience, I just looked at it and it seems I just copied it from __write_card_pp and forgot to implement it. Will fix it soon.

You do not have to hurry. I just found that plain reading the pp_table and writing the same data back will crash the driver (rx560), so I won't be able to use this tool anyway.

You can email me your pp_table and I can check it out locally (and add it to tests). I remember fixing a similar bug where the library corrupted the table as well.

I used dd/cat for that exercise.

cat /sys/class/drm/card0/device/pp_table >pp_table
cat pp_table >/sys/class/drm/card0/device/pp_table

Which crashed the driver (null pointer, but somehow no panic).

Your tool behaves correctly after patching the function with a hard-coded path.

You should patch the function and upload the commit.

This bug has been fixed with commit 2a4ff77
and with pull request #10.
This bug should be closed now.
