[Intel-gfx] [PATCH 00/23] Introduce Rocket Lake

[Intel-gfx] [PATCH 00/23] Introduce Rocket Lake

[Matt Roper]

Rocket Lake (RKL) is another gen12 platform, so the driver support is
mostly a straightforward evolution of our existing Tiger Lake support.

One area of this patch series that's a bit non-intuitive and warrants
some extra explanation is the output handling.  All four of RKL's output
ports use combo PHYs, but the hardware guys have recycled the naming
scheme from Tiger Lake.  The DDI's are still named "A, B, TC1, and TC2"
even though none of them are actually connected to Type-C PHYs on this
platform.  From a register offset perspective, these four DDIs are
effectively A, B, D, and E (skipping over the register range that would
usually be used for a "C" instance of the DDI).  However the PHYs
attached to those DDIs do *not* skip the "C" instance, so we wind up
with the following output relationships:

        DDI-A   (port A) <-> PHY-A
        DDI-B   (port B) <-> PHY-B
        DDI-TC1 (port D) <-> PHY-C
        DDI-TC2 (port E) <-> PHY-D

Given that most of our past platforms have straight DDI==PHY mappings,
extra care is needed to ensure we use the proper namespace (port or phy)
when programming various output-related registers.

[Intel-gfx] [PATCH 07/23] drm/i915/rkl: Limit number of universal planes to 5

[Matt Roper]

RKL only has five universal planes, plus a cursor.  Since the
bottom-most universal plane is considered the primary plane, set the
number of sprites available on this platform to 4.

In general, the plane capabilities of the remaining planes stay the same
as TGL.  However the NV12 Y-plane support moves down to the new top two
planes and now only the bottom three planes can be used for NV12 UV.

[Intel-gfx] [PATCH 08/23] drm/i915/rkl: Add power well support

[Matt Roper]

RKL power wells are similar to TGL power wells, but have some important
differences:

 * PG1 now has pipe A's VDSC (rather than sticking it in PG2)
 * PG2 no longer exists
 * DDI-C (aka TC-1) moves from PG1 -> PG3
 * PG5 no longer exists due to the lack of a fourth pipe

Also note that what we refer to as 'DDI-C' and 'DDI-D' need to actually
be programmed as TC-1 and TC-2 even though this platform doesn't have TC
outputs.

[Intel-gfx] [PATCH 09/23] drm/i915/rkl: Program BW_BUDDY0 registers instead of BW_BUDDY1/2

[Matt Roper]

RKL uses the same BW_BUDDY programming table as TGL, but programs the
values into a single set BUDDY0 set of registers rather than the
BUDDY1/BUDDY2 sets used by TGL.

[Intel-gfx] [PATCH 10/23] drm/i915/rkl: RKL only uses PHY_MISC for PHY's A and B

[Matt Roper]

Since the number of platforms with this restriction are growing, let's
separate out the platform logic into a has_phy_misc() function.

[Intel-gfx] [PATCH 11/23] drm/i915/rkl: Add cdclk support

[Matt Roper]

Note that the 192000 clock frequencies can be achieved with different
pairs of ratio+divider, which is something we haven't encountered
before.  If any of those ratios were common with other legal cdclk
values, then it would mean we could avoid triggering full modesets if we
just needed to change the divider.  However at the moment there don't
appear to be any valid cdclks that share the same ratio so we can't take
advantage of this and it doesn't really matter which approach we use to
achieve the 192000 cdclk.  For now our driver functions that operate on
the table will just always pick the first entry (lower ratio + lower
divider).

[Intel-gfx] [PATCH 15/23] drm/i915/rkl: provide port/phy mapping for vbt

[Matt Roper]

From: Lucas De Marchi <lucas.demarchi@intel.com>

RKL uses the DDI A, DDI B, DDI USBC1, DDI USBC2 from the DE point of
view, so all DDI/pipe/transcoder register use these indexes to refer to
them. Combo phy and IO functions follow another namespace that we keep
as "enum phy". The VBT in theory would use the DE point of view, but
that does not happen in practice.

Provide a table to convert the child devices to the "correct" port
numbering we use. Now this is the output we get while reading the VBT:

DDIA:
[drm:intel_bios_port_aux_ch [i915]] using AUX A for port A (VBT)
[drm:intel_dp_init_connector [i915]] Adding DP connector on [ENCODER:275:DDI A]
[drm:intel_hdmi_init_connector [i915]] Adding HDMI connector on [ENCODER:275:DDI A]
[drm:intel_hdmi_init_connector [i915]] Using DDC pin 0x1 for port A (VBT)

DDIB:
[drm:intel_bios_port_aux_ch [i915]] using AUX B for port B (platform default)
[drm:intel_hdmi_init_connector [i915]] Adding HDMI connector on [ENCODER:291:DDI B]
[drm:intel_hdmi_init_connector [i915]] Using DDC pin 0x2 for port B (VBT)

DDI USBC1:
[drm:intel_bios_port_aux_ch [i915]] using AUX D for port D (VBT)
[drm:intel_dp_init_connector [i915]] Adding DP connector on [ENCODER:295:DDI D]
[drm:intel_hdmi_init_connector [i915]] Adding HDMI connector on [ENCODER:295:DDI D]
[drm:intel_hdmi_init_connector [i915]] Using DDC pin 0x3 for port D (VBT)

DDI USBC2:
[drm:intel_bios_port_aux_ch [i915]] using AUX E for port E (VBT)
[drm:intel_dp_init_connector [i915]] Adding DP connector on [ENCODER:306:DDI E]
[drm:intel_hdmi_init_connector [i915]] Adding HDMI connector on [ENCODER:306:DDI E]
[drm:intel_hdmi_init_connector [i915]] Using DDC pin 0x9 for port E (VBT)

[Intel-gfx] [PATCH 16/23] drm/i915/rkl: Add DDC pin mapping

[Matt Roper]

The pin mapping for the final two outputs varies according to which PCH
is present on the platform:  with TGP the pins are remapped into the TC
range, whereas with CMP they stay in the traditional combo output range.

[Intel-gfx] [PATCH 17/23] drm/i915/rkl: Don't try to access transcoder D

[Matt Roper]

There are a couple places in our driver that loop over transcoders A..D
for gen11+; since RKL only has three pipes/transcoders, this can lead to
unclaimed register reads/writes.  We should add checks for transcoder
existence where appropriate.

[Intel-gfx] [PATCH 19/23] drm/i915/rkl: Handle comp master/slave relationships for PHYs

[Matt Roper]

Certain combo PHYs act as a compensation master to other PHYs and need
to be initialized with a special irefgen bit in the PORT_COMP_DW8
register.  Previously PHY A was the only compensation master (for PHYs
B & C), but RKL adds a fourth PHY which is slaved to PHY C instead.

[Intel-gfx] [PATCH 20/23] drm/i915/rkl: Add DPLL4 support

[Matt Roper]

Rocket Lake has a third DPLL (called 'DPLL4') that must be used to
enable a third display.  Unlike EHL's variant of DPLL4, the RKL variant
behaves the same as DPLL0/1.  And despite its name, the DPLL4 registers
are offset as if it were DPLL2, so no extra offset handling is needed
either.

[Intel-gfx] [PATCH 21/23] drm/i915/rkl: Handle HTI

[Matt Roper]

If HTI (also sometimes called HDPORT) is enabled at startup, it may be
using some of the PHYs and DPLLs making them unavailable for general
usage.  Let's read out the HDPORT_STATE register and avoid making use of
resources that HTI is already using.

[Intel-gfx] [PATCH 22/23] drm/i915/rkl: Disable PSR2

[Matt Roper]

From: José Roberto de Souza <jose.souza@intel.com>

RKL doesn't have PSR2 HW tracking, it was replaced by software/manual
tracking.  The driver is required to track the areas that needs update
and program hardware to send selective updates.

So until the software tracking is implemented, PSR2 needs to be disabled
for platforms without PSR2 HW tracking.

Re: [Intel-gfx] [PATCH 11/23] drm/i915/rkl: Add cdclk support

[Khor, Swee Aun]

Hi Matt,
The follow cdclk doesn't looked right, isn’t it should be 96000 and 540000 according to their respective divider and ratio?
....
+	{ .refclk = 19200, .cdclk = 192000, .divider = 3, .ratio = 15 },
....
+	{ .refclk = 24000, .cdclk = 552000, .divider = 2, .ratio = 45 },
....

Regards,
SweeAun

Subject: [Intel-gfx] [PATCH 11/23] drm/i915/rkl: Add cdclk support

Note that the 192000 clock frequencies can be achieved with different pairs of ratio+divider, which is something we haven't encountered before.  If any of those ratios were common with other legal cdclk values, then it would mean we could avoid triggering full modesets if we just needed to change the divider.  However at the moment there don't appear to be any valid cdclks that share the same ratio so we can't take advantage of this and it doesn't really matter which approach we use to achieve the 192000 cdclk.  For now our driver functions that operate on the table will just always pick the first entry (lower ratio + lower divider).

Yeah, you're right.  The first one appears to have been removed from the
bspec now and the second one appears to be a typo on my part (ratio
should be 46 instead of 45).

Looks like there have been a couple other recent modifications to the
bspec as well that I should update this patch to capture.  Thanks for
pointing that out!

If any of those ratios were common with other legal cdclk values, then it would mean we could avoid triggering full modesets if we just needed to change the divider.  However at the moment there don't appear to be any valid cdclks that share the same ratio so we can't take advantage of this and it doesn't really matter which approach we use to achieve the 192000 cdclk.  For now our driver functions that operate on the table will just always pick the first entry (lower ratio + lower divider).

Actually, it looks like the latest updates in the bspec have now made
the RKL cdclk table identical to the TGL/ICL table.  So we should be
able to drop this patch completely now.

[Intel-gfx] [PATCH v2] drm/i915/rkl: Handle new DPCLKA_CFGCR0 layout

[Matt Roper]

RKL uses a slightly different bit layout for the DPCLKA_CFGCR0 register.

v2:
 - Fix inverted mask application when updating ICL_DPCLKA_CFGCR0
 - Checkpatch style fixes
