2020-10-15drm/i915/dg1: Load DMCMatt Atwood1-3/+9
Add support to load DMC v2.0.2 on DG1 While we're at it, make TGL use the same GEN12 firmware size definition and remove obsolete comment.

2020-06-22drm/i915/params: switch to device specific parametersJani Nikula1-3/+3
Start using device specific parameters instead of module parameters for most things. The module parameters become the immutable initial values for i915 parameters. The device specific parameters in i915->params start life as a copy of i915_modparams. Any later changes are only reflected in the debugfs. The stragglers are: * i915.force_probe and i915.modeset. Needed before dev_priv is available. This is fine because the parameters are read-only and never modified. * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and I915_STATE_WARN_ON would result in massive and ugly churn. This is handled by not exposing the parameter via debugfs, and leaving the parameter writable in sysfs. This may be fixed up in follow-up work. * i915.inject_probe_failure. Only makes sense in terms of the module, not the device. This is handled by not exposing the parameter via debugfs. v2: Fix uc i915 lookup code (Michał Winiarski) Cc: Juha-Pekka Heikkilä <[email protected]> Cc: Venkata Sandeep Dhanalakota <[email protected]> Cc: Michał Winiarski <[email protected]> Reviewed-by: Rodrigo Vivi <[email protected]> Acked-by: Michał Winiarski <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]
2020-06-02drm/i915: Identify Cometlake platformChris Wilson1-1/+3
Cometlake is a small refresh of Coffeelake, but since we have found out a difference in the plaforms, we need to identify them as separate platforms. Since we previously took Coffeelake/Cometlake as identical, update all IS_COFFEELAKE() to also include IS_COMETLAKE().

2020-02-18drm/i915/csr: use intel_de_*() functions for register accessJani Nikula1-5/+6
The implicit "dev_priv" local variable use has been a long-standing pain point in the register access macros I915_READ(), I915_WRITE(), POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW(). Replace them with the corresponding new display engine register accessors intel_de_read(), intel_de_write(), intel_de_posting_read(), intel_de_read_fw(), and intel_de_write_fw(). No functional changes.
