Just include the JSL/EHL DPLL4 extra power domain in the dpll_info struct. This way the same approach could be used by other platforms as well (should the need arise), and we don't have to sprinkle platform checks all over the place. Note that I'm perhaps slightly abusing things here as power_domain==0 (which is actually POWER_DOMAIN_DISPLAY_CORE) now indicates that no extra power domain is needed. I suppose using POWER_DOMAIN_INVALID would be more correct, but then we'd have to sprinkle that to all the other DPLLs. Signed-off-by:

Use named initializers when populating the DPLL info. This is just more convenient and less error prone as we no longer have to keep the initializers in a specific order. Signed-off-by:

Apparently some BDW machines (eg. HP Pavilion 15-ab) shipped with a VBT inherited from some earlier HSW model. On HSW the HDMI level shift value could go up to 11, whereas on BDW the maximum value is 9. The DDI code does clamp the bogus value, but it does so with a WARN which we don't really want. To avoid that let's just sanitize the bogus VBT HDMI level shift value ahead of time for all BDW machines. Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9461Signed-off-by:

eDP specification supports HBR3 link rate since v1.4a. Moreover, C10 phy can support HBR3 link rate for both DP and eDP. Therefore, do not clamp the supported rates for eDP at 6.75Gbps. Cc: <stable@vger.kernel.org> BSpec: 70073 74224 Signed-off-by:

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:Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231016125544.719963-1-mika.kahola@intel.com

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:
