intel_cx0_phy.[ch] should contain the details about C10/C20, not leaking it to the rest of the driver. Start abstracting this by exporting a single PLL hw readout that handles the differences between C20 and C10 internally to that compilation unit. Signed-off-by:

With MTL adding PICA between the port and the real phy, the path add for DG2 stopped being followed and newer platforms are simply using the older path for TC phys. LNL is no different than MTL in this aspect, so just add it to the mess. In future the phy and port designation and deciding if it's TC should better be cleaned up. To make it just a bit better, also change intel_phy_is_snps() to show this is DG2-only. Signed-off-by:

For Lunar Lake, DDI-A is connected to C10 PHY, while TC1-TC3 are connected to C20 phy, like in Meteor Lake. Update the check in intel_is_c10phy() accordingly. This reverts the change in commit e388ae97 ("drm/i915/display: Eliminate IS_METEORLAKE checks") that turned that into a display engine version check. The phy <-> port connection is very SoC-specific and not related to that version. IS_LUNARLAKE() is defined to 0 in i915 as it's expected that the (upcoming) xe driver is the one defining the platform, with i915 only driving the display side. Bspec: 70818 Reviewed-by:

Every know and then we receive the following error when running for example IGT test kms_flip. [drm] *ERROR* PHY G Read 0d80 failed after 3 retries. [drm] *ERROR* PHY G Write 0d81 failed after 3 retries. Since the error is sporadic in nature, the patch proposes to reset the message bus after every successful or unsuccessful read or write operation. v2: Add FIXME's to indicate the experimental nature of this workaround (Rodrigo) v3: Dropping the additional delay as moving reset to *_read_once() and *_write_once() functions seem unnecessary delay Signed-off-by:Mika Kahola <mika.kahola@intel.com> Reviewed-by:

Currently all module parameters are handled by i915_param.c/h. This is a problem for display parameters when Xe driver is used. Add a mechanism to add parameters specific to the display. This is mainly copied from i915_[debugfs]_params.[ch]. Parameters are not yet moved. This is done by subsequent patches. v2: - Drop unused predefinition (dentry) - Clarify need for empty INTEL_DISPLAY_PARAMS_FOR_EACH in comment Signed-off-by:

Meteor Lake has demonstrated consistent stability for some time. All user-space API modifications tide to its core platform functions are operational. The necessary firmware components are set up and comprehensive testing has been condused over a period. Given the recent faborable CI results, as well, we believe it's time to eliminate the 'force_probe' prerequisite and activate the platform by default. Signed-off-by:
