MESA driver is creating protected context on every driver handle creation to query caps bits for app. So when running CI tests, they are observing hundreds of drm_errors when enabling PXP in .config but using SOC fusing or BIOS configuration that cannot support PXP sessions. The fixes tag referenced below was to resolve a related issue where we wanted to silence error messages, but that case was due to outdated IFWI (firmware) that definitely needed an upgrade and was, at that point, considered a one-off case as opposed to today's realization that default CI was enabling PXP in kernel config for all testing. So with this patch, let's strike a balance between issues that is critical but are root-caused from HW/platform gaps (louder drm-warn but just ONCE) vs other cases where it could also come from session state machine (which cannot be a WARN_ONCE since it can be triggered due to runtime operation events). Let's use helpers for these so as more functions are added in future features / HW (or as FW designers continue to bless upstreaming of the error codes and meanings), we only need to update the helpers. NOTE: Don't completely remove FW errors (via drm_debug) or else cusomer apps that really needs to know that content protection failed won't be aware of it. v2: - Add fixes tag (Trvtko) v3: - Break multi-line drm_dbg strings into separate drm_dbg (Daniele) - Fix couple of typecasting nits (Daniele) v4: - Unsuccessful PXP FW cmd due to platform configuration shouldn't use drm_WARN_once (Tvrtko), Switched to use drm_info_once. v5: - Added "reported-and-tested" by Eero.
