Touchscreen support on HP laptops broken due misconfiguration on ACPI
-----BEGIN PGP SIGNED MESSAGE-----

Few months ago, I brought a HP Envy x360 Ryzen 2500u [1] to try the
touchscreen and stylus functions. Unfortunately that support is
currently broken and unresolved inside the kernel for years on previous
models as revealed on the upstream bug report [2].
One of users provided a workaround [3] which needs refinement from
upstream which seems very busy given the time of submitted patch. I
vainly attempted to build a new kernel using the latest snapshot [4]
before filing the bug report on bugzilla[5] linking upstream issue.
What would be great is one of maintainers knowing the field either
building a kernel-test to verify the workaround restoring the
touchscreen support on HP touchscreen laptops running on AMD processors
or build a rawhide version with that patch.
Thanks in advance,
Luya
