Previously, the recommended B credit for all platforms was 24 / number of pipes, which would give 6 for newer platforms with 4 pipes. However 6 is not enough and we need 12 on these cases. We also need a different BW credit for these platforms. Cc: Arthur J Runyan <arthur.j.runyan@intel.com> Signed-off-by:

There are 2 new additional typeC ports in Tiger Lake and PORT-C is now a combophy port. This results in 6 typeC ports and 3 combophy ports. These 6 TC ports can be DP alternate mode, DP over thunderbolt, native DP on legacy DP connector or native HDMI on legacy connector. v2: Rebase on new modular FIA code (Lucas) v3: Also add new port in port_identifier(), even though it can't possibly be used there (requested by José) v4: Add conversion port->tc_port in helper function after introction of phy namespace (Lucas) Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Signed-off-by:Vandita Kulkarni <vandita.kulkarni@intel.com> Signed-off-by:

The patch adds the new power wells introduced by TGL (GEN 12) and maps these to existing/new power domains. The changes for GEN 12 wrt to GEN 11 are the following: - Transcoder#EDP removed from power well#1 (Transcoder#A used in low-power mode instead) - Transcoder#A is now backed by power well#1 instead of power well#3 - The DDI#B/C combo PHY ports are now backed by power well#1 instead of power well#3 - New power well#5 added for pipe#D functionality (TODO) - 2 additional TC ports (TC#5-6) backed by power well#3, 2 port specific IO power wells (only for the non-TBT modes) and 4 port specific AUX power wells (2-2 for TBT vs. non-TBT modes) - Power well#2 backs now VDSC/joining for pipe#A instead of VDSC for eDP and MIPI DSI (TODO) On TGL Port DDI#C changed to be a combo PHY (native DP/HDMI) and BSpec has renamed ports DDI#D-F to TC#4-6 respectively. Thus on ICL we have the following naming for ports: - Combo PHYs (native DP/HDMI): DDI#A-B - TBT/non-TBT (TC altmode, native DP/HDMI) PHYs: DDI#C-F Starting from GEN 12 we have the following naming for ports: - Combo PHYs (native DP/HDMI): DDI#A-C - TBT/non-TBT (TC altmode, native DP/HDMI) PHYs: DDI TC#1-6 To save some space in the power domain enum the power domain naming in the driver reflects the above change, that is power domains TC#1-3 are added as aliases for DDI#D-F and new power domains are reserved for TC#4-6. v2 (Lucas): - Separate out the bits and definitions for TGL from the ICL ones. Fix use of TRANSCODER_EDP_VDSC, that is now the correct define since we don't define TRANSCODER_A_VDSC power domain to spare a one bit in the bitmask (suggested by Ville) v3 (Lucas): - Fix missing squashes on v2 - Rebase on renamed TRANSCODER_EDP_VDSC Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:Imre Deak <imre.deak@intel.com> Signed-off-by:

Currently the intel_update_plane and intel_disable_plane tracepoints record the address of plane->name in the ring buffer, and then when reading the ring buffer uses %s to get the name. The issue with this, is that those two events can be minutes, hours or even days apart. It is very dangerous to dereference a string pointer without knowing if it still exists or not. The proper way to handle this is to use the __string() macro in the tracepoint which will save the string into the ring buffer at the time of recording. Then there's no worries if the original string still exists in memory when the ring buffer is read. Signed-off-by:

The PFI credit programming performed during cdclk change on vlv/chv requires access to a register in the disp2d power well. So far we've abused pipe-A power domain for this, but now we have the more appropriate "display core" domain so let's make use of it. Signed-off-by:

Right idea, wrong lock.

The spec says: "A value of 0 indicates that this buffer does not exist" So we should not convert a hbuf_size of 0 into 1.

We originally added support, in some cases partial, for different modes of operations via guc clients: - proxy vs direct submission; - variable engine mask per-client. We only ever used one flow (all submissions via a single proxy), so the other code paths haven't been exercised and are most likely non-functional. The guc firmware interface is also in the process of being updated to better fit the i915 flow and our client abstraction will need to change accordingly (or possibly go away entirely), so these old unused paths can be considered dead and removed.

Preemption via GuC submission is not being supported with its current legacy incarnation. The current FW does support a similar pre-emption flow via H2G, but it is class-based instead of being instance-based, which doesn't fit well with the i915 tracking. To fix this, the firmware is being updated to better support our needs with a new flow, so we can safely remove the old code. v2 (Daniele): resurrect & rebase, reword commit message, remove preempt_context as well Signed-off-by:

Convert the code that operates directly on gen11 combo PHY's to use the new namespace. Combo PHY registers are those named "ICL_PORT_*" plus ICL_DPHY_CHKN. Note that a lot of the PHY programming happens in the MIPI DSI code. For clarity I've added a for_each_dsi_phy() to loop over the phys used by DSI. Since DSI always uses A & B on gen11, port=phy in all cases so it doesn't actually matter which form we use in the DSI code. I've used the phy iterator in code that's explicitly working with the combo PHY, but left the rest of the DSI code using the port iterator and namespace to minimize patch deltas. We can switch the rest of the DSI code over to use phy terminology later if this winds up being too confusing. v6: Drop an include of drm/i915_drm.h; that was previously included just for the definition of 'enum port' which this patch removes the need for.

Although the register name implies that it operates on DDI's, DPCLKA_CFGCR0_ICL actually needs to be programmed according to the PHY that's in use. I.e., when using EHL's DDI-D on combo PHY A, the bits described as "port A" in the bspec are what we need to set. The bspec clarifies: "[For EHL] DDID clock tied to DDIA clock, so DPCLKA_CFGCR0 DDIA Clock Select chooses the PLL for both DDIA and DDID and drives port A in all cases." Also, since the CNL DPCLKA_CFGCR0 bit defines are still port-based, we create separate ICL-specific defines that accept the PHY rather than trying to share the same bit definitions between CNL and ICL. v5: Make icl_dpclka_cfgcr0_clk_off() take phy rather than port. When splitting the original patch the hunk to handle this wound up too late in the series. (Sparse) v6: Since we're already changing this code, s/DPCLKA_CFGCR0_ICL/ICL_DPCLKA_CFGCR0/ for consistency.

Our past DDI-based Intel platforms have had a fixed DDI<->PHY mapping. Because of this, both the bspec documentation and our i915 code has used the term "port" when talking about either DDI's or PHY's; it was always easy to tell what terms like "Port A" were referring to from the context. Unfortunately this is starting to break down now that EHL allows PHY-A to be driven by either DDI-A or DDI-D. Is a setup with DDI-D driving PHY-A considered "Port A" or "Port D?" The answer depends on which register we're working with, and even the bspec doesn't do a great job of clarifying this. Let's try to be more explicit about whether we're talking about the DDI or the PHY on gen11+ by using 'port' to refer to the DDI and creating a new 'enum phy' namespace to refer to the PHY in use. This patch just adds the new PHY namespace, new phy-based versions of intel_port_is_*(), and a helper to convert a port to a PHY. Transitioning various areas of the code over to using the PHY namespace will be done in subsequent patches to make review easier. We'll remove the intel_port_is_*() functions at the end of the series when we transition all callers over to using the PHY-based versions. v2: - Convert a few more 'port' uses to 'phy.' (Sparse) v3: - Switch DDI_CLK_SEL() back to 'port.' (Jose) - Add a code comment clarifying why DPCLKA_CFGCR0_ICL needs to use PHY for its bit definitions, even though the register description is given in terms of DDI. - To avoid confusion, switch CNL's DPCLKA_CFGCR0 defines back to using port and create separate ICL+ definitions that work in terms of PHY. v4: - Rebase and resolve conflicts with Imre's TC series. - This patch now just adds the namespace and a few convenience functions; the important changes are now split out into separate patches to make review easier.

PORT_TX_DFLEXDPMLE1 is a FIA register so move it to intel_tc.c where we access other FIA registers. In Tiger Lake we have multiple/modular FIAs so it makes sense to start moving all access to their registers to a common place. While at it, make it clear that we will only ever call this function for ports with TC phy. Previously we were relying on tc_mode being TC_PORT_TBT_ALT for combo phy ports. However it's confusing since in this same function we have checks for is_tc_port. Also, if we manage to make each phy access only their own field, we may in future add them as a union inside intel_digital_port. v2: Fix coding style while moving the code Signed-off-by:
