2021-07-22drm/i915/step: Add macro magic for handling stepsAnusha Srivatsa1-15/+23
With the addition of stepping info for all platforms, lets use macros for handling them and autogenerating code for all steps at a time.

2021-07-15drm/i915/skl: Use revid->stepping tablesMatt Roper1-0/+4
Switch SKL to use a revid->stepping table as we're trying to do on all platforms going forward. Also drop the preproduction revisions and add the newer steppings we hadn't already handled. Note that SKL has a case where a newer revision ID corresponds to an older GT/disp stepping (0x9 -> STEP_J0, 0xA -> STEP_I1). Also, the lack of a revision ID 0x8 in the table is intentional and not an oversight. We'll re-write the KBL-specific comment to make it clear that these kind of quirks are expected. v2: - Since GT and display steppings are always identical on SKL use a macro to set both values at once in a more readable manner. (Anusha) - Drop preproduction steppings.

2021-03-29drm/i915: rename i915_rev_steppings->intel_step_infoJani Nikula1-1/+1
Matter of taste. Match the prefix for everything else related to steppings. No functional changes.

2021-03-29drm/i915: switch TGL and ADL to the new stepping schemeJani Nikula1-8/+0
This changes the way revids not present in the array are handled: - For gaps in the array, the next present revid is used. - For revids beyond the array, the new STEP_FUTURE is used instead of the last revid in the array. In both cases, we'll get debug logging of what's going on. v2: Rename stepping->step Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/756fe3d75b1e91ef812fc1fd3f70337e9c571d91.1616764798.git.jani.nikula@intel.com
2021-03-29drm/i915: switch KBL to the new stepping schemeJani Nikula1-1/+10
Add new symbolic names for revision ids, and convert KBL revids to use them via the new stepping check macros. This also fixes theoretical out of bounds access to kbl_revids array. v3: upgrade dbg to warn on unknown revid (José) v2: Rename stepping->step Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/79b6c48211c6b214165391d350d556bad748f747.1616764798.git.jani.nikula@intel.com
2021-03-29drm/i915: add new helpers for accessing stepping infoJani Nikula1-0/+14
Add new runtime info field for stepping. Add new helpers for accessing them. As we'll be switching platforms over to the new scheme incrementally, check for non-initialized steppings. In case a platform does not have separate display and gt steppings, it's okay to use a common shorthand. However, in this case the display stepping must not be initialized, and gt stepping is the single point of truth. v3: Remove IS_STEP() (José) v2: Rename stepping->step Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/bb4275733fa390ea3dbf6f62794d55b616665230.1616764798.git.jani.nikula@intel.com
