Initialization sequences and C10 phy are in place to be able to enable

XELPDP has C10 and C20 phys from Synopsys to drive displays. Each phy
has a dedicated PIPE 5.2 Message bus for configuration. This message
bus is used to configure the phy internal registers.
XELPDP has C10 phys to drive output to the EDP and the native output
from the display engine. Add structures, programming hardware state
readout logic. Port clock calculations are similar to DG2. Use the DG2
formulae to calculate the port clock but use the relevant pll signals.
Note: PHY lane 0 is always used for PLL programming.
Add sequences for C10 phy enable/disable phy lane reset,
powerdown change sequence and phy lane programming.
Bspec: 64539, 64568, 64599, 65100, 65101, 65450, 65451, 67610, 67636
v2: Squash patches related to C10 phy message bus and pll
programming support (Jani)
Move register definitions to a new file i.e. intel_cx0_reg_defs.h (Jani)
Move macro definitions (Jani)
DP rates as separate patch (Jani)
Spin out xelpdp register definitions into a separate file (Jani)
Replace macro to select registers based on phy lane with
function calls (Jani)
Fix styling issues (Jani)
Call XELPDP_PORT_P2M_MSGBUS_STATUS() with port instead of phy (Lucas)
v3: Move clear request flag into try-loop
v4: On PHY idle change drm_err_once() as drm_dbg_kms() (Jani)
use __intel_de_wait_for_register() instead of __intel_wait_for_register
and uncomment intel_uncore.h (Jani)
Add DP-alt support for PHY lane programming (Khaled)

For the above and every other place taking a lane mask parameter or
converting the lane mask to a lane:
I think the function parameter should be an 'u8 lane_mask' for clarity
and instead of open-coding the conversion should be done by a
lane_mask_to_lane() helper which also sanity checks lane_mask (that it's
either INTEL_CX0_LANE0 or INTEL_CX0_LANE1, but not both).

The above should write only the XELPDP_PORT_P2M_RESPONSE_READY and
XELPDP_PORT_P2M_ERROR_SET flags to get those cleared.
Could factor out a function for it since the same is also used later.

As above this function should take the 0-based lane value.

Please add a comment why this retries 3 times, doesn't seem to be
described by the spec.

val could be removed as it's not used, and remove the last param from
__intel_cx0_read() accordingly.

Returning status here would simplify the code below.

The spec says (65451):
"Only update powerdown for one port at a time. Wait for powerdown
update to finish for one port before initiating update on another port."
both could be updated at the same time if a non-zero stagger delay was
programmed, but for C10/C20 it must be programmed as 0.

Err, I meant here as earlier the function param should be
'u8 lane_mask' and use a helper to convert this mask to a lane.

I think this plays on the safe side. If transaction is not completed withing reasonable time, we set the bus in known state. What would be the alternative? Just leave the bus state as is?

Ok, I'll add a comment for read/write tries. This hasn't been specified in spec so the number of retries could be anything.

Maybe I'm not really following here but intel_c20pll_state has its own tx, cmn and mplla/mpllb stored.

Usually this means that we are not accessing these values from the register. Was this in the spec that we would need to clear it?

The spec says that with pin assignment D the lane 0 is owned by display. Lane 1 is owned by USB and shouldn't be programmed as the PHY will not respond.

Not sure, since it's not specified; neither it is clear if it has
side-effects. In any case as I understand someone has actually seen this
being required after a transaction times out. If so please add a comment
both to here and to the 3-time retry loop, that neither of these are
required by the spec, but used as a workaround for these timeouts. (Also
I guess we'd need open HSD/bspec tickets for such WAs we came up with).

Yes, just typoed that, I meant struct intel_c10mpllb_state which doesn't
include tx and cmn.

It does get cleared at the end of intel_c10_pll_program(), at least from
one of the PHY lanes, so was wondering why things are done differently
here. Yes, the spec doesn't require clearing it, but then it should not
be cleared at other places either (has related comments on this in
follow-up reviews).

Right, but both lanes are programmed. So would need a "FIXME: program only
lane 0 for DP-alt / MFD" comment.

I think it could be fixed up later with all other places programming now
both PHY lanes unconditionally, adding only a TODO: comment here for now.

Let's play it safe. I add a comment here for the reset.

Yes, for C10 tx and cmn is missing. Maybe we could add those here as well. It seems that currently these are not necessary required but for the future use, these could be defined.

To be consistent maybe we can clear this here as well.

These are needed already now to make the state computation / HW readout /
state checking work for these two params the same way they do for the
rest of PLL state.

If there is no need for it, let's follow the spec and not clear it at

I believe C10 tx and cmn values are not changing across frequencies. Cmn on ly
Changes for DP and HDMI so does it make sense to include in the pll structure?

They should be part of the atomic state. To save the bytes in the
precomputed tables they could be added to intel_cx0pll_state, something
like:
struct intel_cx0pll_state {
union {
struct {
struct intel_c10mpllb_state pllb;
u8 cmn;
u8 tx;
} c10;
struct intel_c20pll_state c20pll_state;
};
};

I am bit concerned about the mismatch in the names for c10 and c20 states,
adding further complexity in the structure may look more ugly. Let us afford the
extra space in the tables if they need to be part of the atomic state and maintain
homogeneity across c10 and c20 structures.
Thoughts?

Shouldn't the basic MTL DP/HDMI modeset sequences be part of this
patchset? I can't see how things would work otherwise. For DP it is the
"drm/i915/mtl/display: Implement DisplayPort sequences"
patch in the internal tree.

This programs the PLL via the INTEL_CX0_LANE1 lane in the
lane_reversal=true case. However, I haven't found any trace of this
being correct in the spec. It just says that PLL must be programmed via
INTEL_CX0_LANE0 in all the cases, so both for lane_reversal and
!lane_reversal (see Bspec/64539 "Phy Lane and Transmitter Usage"
table/"Lane for message bus PLL programming" column).

As this series enables eDP and HDMI on C10, the parts that make this
working should be in this patchset imo. C20 and TBT doesn't need to be,
but I don't see how eDP or HDMI on C10 would work if the modeset
sequence used for both C10 and C20 and both DP and HDMI modes is not
updated for MTL.

That's what the spec says at least, so I don't see a reason to not
follow that.

Yes, there is no FIELD_PREP8(), so I assume the reference was about
FIELD_PREP().

The whole split is a bit artificial as it was really hard to get any reviews done for the whole series. But you are right, the hdmi is not needed to eDP support. Maybe for the next round, I drop these hdmi related patches out from the C10 series so we can get only eDP support reviewed and merged at some point.

Like DG2, we still don't have a proper algorithm that can be used
for calculating PHY settings, but we do have tables of register
values for a handful of the more common link rates. Some support is
better than none, so let's go ahead and add/use these tables when we
can, and also add some logic to hdmi_port_clock_valid() to filter the
modelist to just the modes we can actually support with these link
rates.
Hopefully we'll have a proper / non-encumbered algorithm to calculate
these registers by the time we upstream and we'll be able to replace
this patch with something more general purpose.

This should just read out the cmn0 and tx0 registers and store them to
pll_state, while the check should be done in

This should be set up with the rest of pll values and the tx0 value in
intel_c10mpllb_calc_state(), storing them to
crtc_state->cx0pll_state.c10mpllb_state, while this function should just
program these to their registers.

The above should rely only on the HW state, not the SW new_crtc_state.
To deduct the HDMI/DP mode C10_PLL15_HDMIDIV_MASK/pll_state->pll[15] can

C10 phys uses direct mapping internally for voltage and pre-emphasis levels.
Program the levels directly to the fields in the VDR Registers.
Bspec: 65449
v2: From table "C10: Tx EQ settings for DP 1.4x" it shows level 1
and preemphasis 1 instead of two times of level 1 preemphasis 0.
Fix this in the driver code as well.
v3: VSwing update (Clint)

This along with intel_cx0_phy_transaction_begin()/end() could be moved

The spec says to program here the
VDR common offset 12'hC31 for TX termination control
and
VDR common offset 12'hC23 for TX vboost level
see bspec/74103.

Should program only the lanes up to crtc_state->lane_count.

Instead of the above magic conversions, would be better to have helpers, stg like:
phy_lane = lane_to_phy_lane(ln);
tx = lane_to_phy_lane_tx(ln);
phy_lane_mask = lane_to_phy_lane_mask(ln);
lane_reversal and the DP-alt mode is not accounted for here, for
instance phy lane#0/tx#1 will be programmed instead of phy lane#1/tx#2.
Either this needs to be fixed or needs a FIXME: comment.

Only the used/owned PHY lanes should be programmed.

I don't think this should change the MASTER_LANE flag, which only
controls where the PLL parameters are programmed and is already set up
during PLL enabling. Also I don't see a reason to differentiate between
"master" and "follower" PHY lanes here. I think the above two should
simply set the C10_VCR_CTRL_UPDATE_CFG flag in both PHY lanes, using
intel_cx0_rmw().

I suppose this change should be in a C20 patchset, as PLLA is not used
in C10 PHYs.

As above, this shouldn't change the MASTER_LANE flag (now it contradicts
the programming during pll enabling and vswing setting for the
lane_reversal=true case). Probably the MSGBUS_ACCESS flag doesn't need
to be cleared either, at least I can't see bspec requiring it. So just set the
C10_VDR_CTRL_UPDATE_CFG flag in the programmed PHY lanes.

This looks like a fix-up, if required should be part of the patch adding

Flag indentation is missing.
Instead of open-coding there should be defines like
CX0_VDR_CONTROL_TX1 0

From: Mika Kahola @ 2023-03-27 12:34 UTC (permalink / raw)
To: intel-gfx; +Cc: Lucas De Marchi, Matt Roper
Display14 introduces a new way to instruct the PUnit with
power and bandwidth requirements of DE. Add the functionality
to program the registers and handle waits using interrupts.
The current wait time for timeouts is programmed for 10 msecs to
factor in the worst case scenarios. Changes made to use REG_BIT
for a register that we touched(GEN8_DE_MISC_IER _MMIO).
v2:
- Removed repeated definition of dbuf, which has been moved to struct
intel_display. (Gustavo)
- s/dev_priv->dbuf/dev_priv->display.dbuf/ (Gustavo)
