[Intel-gfx] [PATCH v2 00/50] Introduce Alder Lake-P

[Intel-gfx] [PATCH v2 00/50] Introduce Alder Lake-P

[Matt Roper]

The previous version of this series was here:
        https://lists.freedesktop.org/archives/intel-gfx/2021-March/262168.html

The preparation patches that convert display/ to use DISPLAY_VER()
instead of INTEL_GEN() have landed on drm-tip now, so this is mostly
just a straightforward rebase of the remaining patches.  I think there
was only one minor functional fix to the last patch of the series (PSR
changes).

[Intel-gfx] [PATCH v2 01/50] drm/i915/xelpd: add XE_LPD display characteristics

[Matt Roper]

Let's start preparing for upcoming platforms that will use an XE_LPD
design.

v2:
 - Use the now-preferred "XE_LPD" term to refer to this design
 - Utilize DISPLAY_VER() rather than a feature flag
 - Drop unused mbus_size field (Lucas)

[Intel-gfx] [PATCH v2 02/50] drm/i915/xelpd: Handle proper AUX interrupt bits

[Matt Roper]

XE_LPD has new AUX interrupt bits for DDI-D and DDI-E that take the
spots that were used by TC5/TC6 on Display12 platforms.

While we're at it, let's convert the bit definitions for all TGL+ aux
bits over to the modern REG_BIT() notation.

v2:
 - Maintain bit order rather than logical order.  (Lucas)
 - Convert surrounding code to REG_BIT() notation.  (Lucas)

[Intel-gfx] [PATCH v2 03/50] drm/i915/xelpd: Enhanced pipe underrun reporting

[Matt Roper]

XE_LPD brings enhanced underrun recovery:  the hardware can somewhat
mitigate underruns by using an interpolated replacement pixel (soft
underrun) or the previous pixel (hard underrun).  Furthermore, underruns
can now be caused downstream by the port, even if the pipe itself is
operating properly.  The interrupt register and PIPE_STATUS register
give us extra bits to recognize hard/soft underruns and determine
whether the underrun was caused by the port, so we'll use that
information to print some more descriptive errors when underruns occur.

v2:
 - Keep ICL's PIPE_STATUS defined separately from the old GMCH pipe
   status register.  (Ville)
 - Only read/clear the PIPE_STATUS register on platforms with
   display ver >= 11. (Lucas)

[Intel-gfx] [PATCH v2 04/50] drm/i915/xelpd: Define plane capabilities

[Matt Roper]

XE_LPD's plane support is identical to RKL and ADL-S --- 5 universal + 1
cursor with NV12 UV support on planes 1-3 and NV12 Y support on planes
4-5.

v2:
 - Drop the extra 90/270 rotation check in skl_plane_check_fb(); the DRM
   property code will already prevent userspace from passing us values
   that weren't advertised.  (Lucas)

[Intel-gfx] [PATCH v2 06/50] drm/i915/xelpd: Handle new location of outputs D and E

[Matt Roper]

The DDI naming template for display version 12 went A-C, TC1-TC6.  With
XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4.

The XE_LPD design keeps the register offsets and bitfields relating to
the TC outputs in the same location they were previously.  The new "D"
and "E" outputs now take the locations that were previously used by TC5
and TC6 outputs, or what we would have considered to be outputs "H" and
"I" under the legacy lettering scheme.

For the most part everything will just work as long as we initialize the
output with the proper 'enum port' value.  However we do need to take
care to pick the correct AUX channel when parsing the VBT (e.g., a
reference to 'AUX D' is actually asking us to use the 8th aux channel,
not the fourth).  We should also make sure that our encoders and aux
channels are named appropriately so that it's easier to correlate driver
debug messages with the bspec instructions.

v2:
 - Update handling of TGL_TRANS_CLK_SEL_PORT.  (Jose)

[Intel-gfx] [PATCH v2 07/50] drm/i915/xelpd: Add XE_LPD power wells

[Matt Roper]

Aside from the hardware-managed PG0, XE_LPD has power wells 1-2 and
A-D.  These power wells should be enabled/disabled according to the
following dependency tree (enable top to bottom, disable bottom to top):

               PG0
                |
             --PG1--
            /       \
          PGA     --PG2--
                 /   |   \
               PGB  PGC  PGD

PWR_WELL_CTL follows the general ICL/TGL design and places PG A-D in the
bits that would have been PG 6-9 under the old scheme.

PWR_WELL_CTL_{DDI,AUX}'s bit indexing for DDI's A-C and TC1 is the same
as TGL, but DDI-D is placed at index 7 (bits 14 & 15).

[Intel-gfx] [PATCH v2 08/50] drm/i915/xelpd: Handle LPSP for XE_LPD

[Matt Roper]

From: Uma Shankar <uma.shankar@intel.com>

Enable LPSP for XE_LPD and get the proper power well
enable check in place. For XE_LPD it is PW2 which
need to check for LPSP.

v2:
 - Move the XE_LPD check outside of the switch.  (Lucas)

[Intel-gfx] [PATCH v2 09/50] drm/i915/xelpd: Increase maximum watermark lines to 255

[Matt Roper]

XE_LPD continues to use the same "skylake-style" watermark
programming as other recent platforms.  The only change to the watermark
calculations compared to Display12 is that XE_LPD now allows a
maximum of 255 lines vs the old limit of 31.

Due to the larger possible lines value, the corresponding bits
representing the value in PLANE_WM are also extended, so make sure we
read/write enough bits.  Let's also take this opportunity to switch over
to the REG_FIELD notation.

[Intel-gfx] [PATCH v2 15/50] drm/i915/xelpd: Calculate VDSC RC parameters

[Matt Roper]

From: Vandita Kulkarni <vandita.kulkarni@intel.com>

Add methods to calculate rc parameters for all bpps, against the fixed
arrays that we already have for 8,10,12 valid o/p bpps, to cover RGB 444
formats.  Our hw doesn't support YUV compression yet.  The calculations
used here are from VESA C model for DSC 1.1

v2:
 - Checkpatch fixes

[Intel-gfx] [PATCH v2 16/50] drm/i915/xelpd: Add rc_qp_table for rcparams calculation

[Matt Roper]

From: Vandita Kulkarni <vandita.kulkarni@intel.com>

Add the qp table for 444 formats, for 8bpc, 10bpc and 12bpc, as given by
the VESA C model for DSC 1.1

v2:
 - Add include guard to header (Jani)
 - Move the big tables to a .c file (Chris, Jani, Lucas)

[Intel-gfx] [PATCH v2 17/50] drm/i915/xelpd: Add VRR guardband for VRR CTL

[Matt Roper]

From: Manasi Navare <manasi.d.navare@intel.com>

On XE_LPD, VRR CTL register adds a new VRR Guardband bitfield
replacing the pipeline full and deprecating the pipeline override
bit.

This patch adds this corresponding bitfield in the register defs,
crtc state vrr structure and populates this in vrr compute
config and vrr enable functions. It also adds the corresponding
HW state readout for this field.

[Intel-gfx] [PATCH v2 20/50] drm/i915/adl_p: Add PCH support

[Matt Roper]

From: Clinton Taylor <Clinton.A.Taylor@intel.com>

Add ADP-P PCH device ID and assign as ADL PCH if found. Previously we
would assign the DDC pin map based on the PCH, but it can also change
based on the CPU. From Bspec 20124: "The physical port to pin pair
mapping are defined in the Bspec per PCH. Mapping can further change
based on CPU Si used as CPU and PCH can be mixed and matched".

[Intel-gfx] [PATCH v2 21/50] drm/i915/adl_p: Add dedicated SAGV watermarks

[Matt Roper]

XE_LPD reduces the number of regular watermark latency levels from 8
to 6 on non-dgfx platforms.  However the hardware also adds a special
purpose SAGV wateramrk (and an accompanying transition watermark) that
will be used by the hardware in place of the level 0 values during SAGV
transitions.

[Intel-gfx] [PATCH v2 22/50] drm/i915/adl_p: Extend PLANE_WM bits for blocks & lines

[Matt Roper]

ADL-P further extends the bits in PLANE_WM that represent blocks and
lines; we need to extend our masks accordingly.  Since these bits are
reserved and MBZ on earlier platforms, it's safe to use the larger
bitmask on all platforms.

[Intel-gfx] [PATCH v2 26/50] drm/i915/display/tc: Rename safe_mode functions ownership

[Matt Roper]

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

When DP_PHY_MODE_STATUS_NOT_SAFE is set, it means that display
has the control over the TC phy.
The "not safe" naming is confusing using ownership make it easier
to read also future platforms will have a new register that does the
same job as DP_PHY_MODE_STATUS_NOT_SAFE but with the onwership name.

[Intel-gfx] [PATCH v2 27/50] drm/i915/adl_p: Handle TC cold

[Matt Roper]

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

On ADL-P TC cold is exited and blocked when legacy aux is powered,
that is exacly the same of what ICL need for static TC ports.

TODO: When a TBT hub or monitor is connected it will cause TBT and
legacy aux to be powered at the same time, hopefully this will not
cause any issues but if it do, some rework will be needed.

[Intel-gfx] [PATCH v2 28/50] drm/i915/adl_p: Implement TC sequences

[Matt Roper]

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

ADL-P have basically the same TC connection and disconnection
sequences as ICL and TGL, the major difference is the new registers.

So here adding functions without the icl prefix in the name and
making the new functions call the platform specific function to access
the correct register.

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

Alderlake P have modular FIA like TGL but it is always modular in all
skus, not like TGL that we had to read a register to check if it is
monolithic or modular.

[Intel-gfx] [PATCH v2 30/50] drm/i915/adl_p: Don't config MBUS and DBUF during display initialization

[Matt Roper]

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

Alderlake-P don't have programing sequences for MBUS or DBUF during
display initializaiton, instead it requires programing to those
registers during modeset because it to depend on the pipes left
enabled.

[Intel-gfx] [PATCH v2 32/50] drm/i915: Introduce MBUS relative dbuf offsets

[Matt Roper]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The dbuf slices are going to be split across several MBUS units.
The actual dbuf programming will use offsets relative to the
MBUS unit. To accomodate that we shall store the MBUS relative
offsets into the dbuf_state->ddb[] and crtc_state->plane_ddb*[].

For crtc_state->wm.skl.ddb however we want to stick to global
offsets as we use this to sanity check that the ddb allocations
don't overlap between pipes.

[Intel-gfx] [PATCH v2 35/50] drm/i915/adl_p: Tx escape clock with DSI

[Matt Roper]

From: Mika Kahola <mika.kahola@intel.com>

Today when the DSI controller is paired with the Combo-PHY it
uses the high-speed (HS) Word clock for its low power (LP)
transmit PPI communication to the DPHY. The interface signaling
only changes state at an Escape clock frequency (i.e. its
effectively running on a virtual Tx Escape clock that is controlled
by counters w/in the controller), but all the interface flops are
running off the HS clock.

This has the following drawbacks:

 * It is a deviation from the PPI spec which assumes signaling is
   running on a physical Escape clock
 * The PV timings are over constrained (HS timed to 312.5MHz vs.
   an Escape clock of 20MHz max)

This feature is proposing to change the LP Tx communication between
the controller and the DPHY from a virtual Tx Escape clock to a physical
clock.

To do this we need to program two "M" divisors. One for the usual
DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV register and one for MIPIO_DWORD8.

For DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV registers the "M" is calculated
as following

Nt = ceil(f_link/160) (theoretical word clock)
Nact = max[3, Nt + (Nt + 1)%2] (actual word clock)
M = Nact * 8

For MIPIO_DWORD8 register, the divisor "M" is calculated as following

M = (Nact - 1)/2

BSpec: 55171

[Intel-gfx] [PATCH v2 40/50] drm/i915/adl_p: Add PLL Support

[Matt Roper]

From: Anusha Srivatsa <anusha.srivatsa@intel.com>

The clocks in ALD_P is similar to that of TGL.
The combo PLLs  use the same DPLL0, DPLL1 and TBT_PLL.

This patch adds the helper function intel_mg_pll_enable_reg()
which is similar to intel_combo_pll_enable_reg() for being lookup
place for PLL_ENABLE register in combo phy cases.

[Intel-gfx] [PATCH v2 44/50] drm/i915/adlp: Add PIPE_MISC2 programming

[Matt Roper]

From: Anusha Srivatsa <anusha.srivatsa@intel.com>

When scalers are enabled, we need to program underrun
bubble counter to 0x50 to avoid Soft Pipe A underruns.

[Intel-gfx] [PATCH v2 50/50] drm/i915/display/adl_p: Implement PSR changes

[Matt Roper]

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

Implements changes around PSR for alderlake-P:

- EDP_SU_TRACK_ENABLE was removed and bit 30 now has other function
- Some bits of PSR2_MAN_TRK_CTL moved and SF_PARTIAL_FRAME_UPDATE was
  removed setting SU_REGION_START/END_ADDR will do this job
- SU_REGION_START/END_ADDR have now line granularity but will need to
  be aligned with DSC when the PSRS + DSC support lands

v2:
 - Don't lose EDP_PSR2_ENABLE bit in hsw_activate_psr2() (Gwan-gyeong)

We need to retain this flag during modeset; we can just set it
unconditionally in intel_ddi_init_dp_buf_reg() for legacy and dp-alt
mode.

Setting this flags isn't needed any more by the spec (bspec 54956).

On TypeC DDIs in dp-alt and legacy mode the DDI_BUF_CTL 'Phy link rate'
field must be also set according to crtc_state->port_clock (in
intel_ddi_init_dp_buf_reg()), see bspec 49533.
