There are two issues with the current RPCS programming for Icelake: Expansion of the slice count bitfield has been missed, as well as the required programming workaround for the subslice count bitfield size limitation. 1) Bitfield width for configuring the active slice count has grown so we need to program the GEN8_R_PWR_CLK_STATE accordingly. Current code was always requesting eight times the number of slices (due writing to a bitfield starting three bits higher than it should). These requests were luckily a) capped by the hardware to the available number of slices, and b) we haven't yet exported the code to ask for reduced slice configurations. Due both of the above there was no impact from this incorrect programming but we should still fix it. 2) Due subslice count bitfield being only three bits wide and furthermore capped to a maximum documented value of four, special programming workaround is needed to enable more than four subslices. With this programming driver has to consider the GT configuration as 2x4x8, while the hardware internally translates this to 1x8x8. A limitation stemming from this is that either a subslice count between one and four can be selected, or a subslice count equaling the total number of subslices in all selected slices. In other words, odd subslice counts greater than four are impossible, as are odd subslice counts greater than a single slice subslice count. This also had no impact in the current code base due breakage from 1) always reqesting more than one slice. While fixing this we also add some asserts to flag up any future bitfield overflows. v2: * Use a local in all branches for clarity.

Unlike the other ports, TC ports are not available to use as soon as we get a hotplug. The TC PHYs can be shared between multiple controllers: display, USB, etc. As a result, handshaking through FIA is required around connect and disconnect to cleanly transfer ownership with the controller and set the type-C power state. This patch implements the flow sequences described by our specification. We opt to grab ownership of the ports as soon as we get the hotplugs in order to simplify the interactions and avoid surprises in the user space side. We may consider changing this in the future, once we improve our testing capabilities on this area. v2: * This unifies the DP and HDMI patches so we can discuss everything at once so people looking at random single patches can actually understand the direction. * I found out the spec was updated a while ago. There's a small difference in the connect flow and the patch was updated for that. * Our spec also now gives a good explanation on what is really happening. As a result, comments were added. * Add some more comments as requested by Rodrigo (Rodrigo). v3: * Downgrade a DRM_ERROR that shouldn't ever happen but we can't act on in case it does (Chris).

Since Haswell we have no color range indication either in the pipe or port registers for DP. Instead, there's a separate register for setting the DP Main Stream Attributes (MSA) directly. The MSA register definition makes no references to colorimetry, just a vague reference to the DP spec. The connection to the color range was lost. Apparently we've failed to set the proper MSA bit for limited, or CEA, range ever since the first DDI platforms. We've started setting other MSA parameters since commit dae84799 ("drm/i915: add intel_ddi_set_pipe_settings"). Without the crucial bit of information, the DP sink has no way of knowing the source is actually transmitting limited range RGB, leading to "washed out" colors. With the colorimetry information, compliant sinks should be able to handle the limited range properly. Native (i.e. non-LSPCON) HDMI was not affected because we do pass the color range via AVI infoframes. Though not the root cause, the problem was made worse for DDI platforms with commit 55bc60db ("drm/i915: Add "Automatic" mode for the "Broadcast RGB" property"), which selects limited range RGB automatically based on the mode, as per the DP, HDMI and CEA specs. After all these years, the fix boils down to flipping one bit. [Per testing reports, this fixes DP sinks, but not the LSPCON. My educated guess is that the LSPCON fails to turn the CEA range MSA into AVI infoframes for HDMI.] Reported-by: NMichał Kopeć <mkopec12@gmail.com> Reported-by: NN.

Now that we removed dependence on the power well IDs to determine the control register and request/status flag offsets the only purpose of power well IDs is to look up power wells directly bypassing the power domains framework. However this direct lookup isn't needed for most of the exisiting power wells and hopefully won't be needed for any new power wells in the future. To make maintenance of the power well ID enum easier, don't require a unique ID for each power well, only if it's necessary. Remove the IDs becoming redundant this way and assign to all the corresponding power wells a new DISP_PW_ID_NONE ID. After the previous two patches the IDs don't need to have a fixed value, so remove the explicit initializers and adjust the enum's code comment accordingly. v2: - Keep required ID assignments for HSW_DISP_PW_GLOBAL and ICL_DISP_PW_2.

Similarly to the previous patch use a separate request/status HW flag index defined right after the corresponding control registers instead of depending for this on the power well IDs. Since the set of control/status registers varies among the different power wells (on a single platform), also add a new i915_power_well_registers struct that we populate and assign to each DDI power well as needed. Also clarify a bit the code comment describing the function and layout of the control registers. This also fixes a problem on ICL, where we incorrectly read the KVMR control register in hsw_power_well_requesters() even for DDI and AUX power wells. v2: - Clarify platform range tags in code comments.

Atm, we determine the control/status flag offsets within the PUNIT control/status registers based on the power well's ID. Since the power well ID enum is global across all platforms, the associated macros to get the flag offsets involves some magic. This makes checking the register/bit definitions against the specification more difficult than necessary. Also the values in the power well ID enum must stay fixed, making code maintenance of the enum cumbersome. To solve the above define the control/status flag indices right after the corresponding registers and use these to derive the control/status flag values by storing the indices in the i915_power_well_desc struct. Initializing anonymous union fields require the preceding field in the struct to be explicitly initialized - even when using named initializers - and the initialization to be done right before the union initialization, hence the reordering of the .id fields. v2: - Clarify commit log message about anonymous union initializers.

Apparently the register toggle is deprecated. Remove the register toggle as evidence shows it's futile. The thing remaining is an apology and humble request for Mesa folks to resurrect their state setup for this as they were on right track from start. This reverts commit 0bf059f3.

Do like the other functions and check for the status bits.

This patch adds the remaining register definitions and bit fields required for MG PHy DDI buffer initializations and voltage swing programming for MG PHy DDI ports. While at it this patch also fixes the naming for previously defined MG PHY registers in original commit id (c92f47b5 "drm/i915/icl: Add register defs for voltage swing sequences for MG PHY DDI"). Since the MG PHY registers are first defined in ICL platform, there is no need for _ICL prefix. v4 (from Paulo): add two white spaces to CRI_CALCINIT too. v3: * Fix register names, add spaces for MASK defines, correct the order of #defines (Paulo) v2: * Change the MG_TX_DRVCTL registers names to match the spec (Anusha) Cc: James Ausmus <james.ausmus@intel.com> Reviewed-by: NPaulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: NManasi Navare <manasi.d.navare@intel.com> Signed-off-by: NPaulo Zanoni <paulo.r.zanoni@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1531510993-6606-1-git-send-email-manasi.d.navare@intel.com
