[PATCH 00/22] Tiger Lake part 2

[PATCH 00/22] Tiger Lake part 2

[Lucas De Marchi]

Second batch of patches for basic platform definition for Tiger Lake.
This includes some patches from the first batch
(https://patchwork.freedesktop.org/series/62726/) but that were removed
in order to merge that series earlier.

Stolen memory is on its own:
https://patchwork.freedesktop.org/series/63665/

This one includes: hotplug detection, initial support for Dekel phy (the
TC phy replacing MG from Ice Lake), support to load the DMC firmware,
some DP interrupts, initial workarounds and MOCS table.

[PATCH 01/22] drm/i915/tgl: skip setting PORT_CL_DW12_* on initialization

[Lucas De Marchi]

According to the spec when initializing the display in TGL we should not
set PORT_CL_DW12 for the Aux channel of the combo PHYs. We will re-use the
power well hooks from ICL so only set this register on gen < 12.

v2: Generalize check for gen 12 (suggested by José)
v3: Rebase after enum phy introduction

[PATCH 02/22] drm/i915/tgl: select correct bit for port select

[Lucas De Marchi]

From: Mahesh Kumar <mahesh1.kumar@intel.com>

Bit definitions for port-select got changed for TRANS_CLK_SEL &
TRANS_DDI_FUNC_CTL registers in TGL.

v2 (Lucas):
  - Nuke TRANS_DDI_PORT_NONE since it's 0: we are already clearing
    {TGL_,}TRANS_DDI_PORT_MASK (suggested by Ville)
  - Also cover haswell_get_ddi_port_state() in intel_display.c that was
    missing
  - Define macros using the _SHIFT macros so we don't lose other users

[PATCH 03/22] drm/i915/tgl: update ddi/tc clock_off bits

[Lucas De Marchi]

From: Mahesh Kumar <mahesh1.kumar@intel.com>

In GEN 12 PORT_C DDI clk_off bit is not equally distanced to A/B,
it's at offset 24. Similarly TC port (5/6) clk off bits are at
offset 22/23. Extend the macros to cover the additional ports.

[PATCH 04/22] drm/i915/tgl: Add hpd interrupt handling

[Lucas De Marchi]

Add hotdplug detection for all ports on TGP. icp_hpd_detection_setup()
is refactored to be shared with TGP.

While we increase the number of pins, add a BUILD_BUG_ON() to avoid
going over the number of bits allowed.

[PATCH 05/22] drm/i915/tgl: Update north display hotplug detection to TGL connections

[Lucas De Marchi]

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

TGL has 3 combophys and 6 TC/TBT ports, so it has 2 more TC/TBT ports
than ICL and the PORT_C on TGL is a combophy.
So here adding a new hpd north table and function to detect long
pulse for TGL.

[PATCH 08/22] drm/i915/tgl: Add DKL phy pll registers

[Lucas De Marchi]

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

These are the registers needed to program Dekel PHY. Some register
definitions reuse the MG PHY definitions. Add a comment on those so we
don't need to duplicate the functions for programming them.

[PATCH 09/22] drm/i915/tgl: re-indent code to prepare for DKL changes

[Lucas De Marchi]

The final save operation into pll_state of the calculations done will
be different for DKL PHY. Prepare for that by reindenting code so it's
easier to check for correctness. This one has no change in behavior.

[PATCH 11/22] drm/i915/tgl: start adding the DKL PLLs to use on TC ports

[Lucas De Marchi]

The disable function can be the same as for MG phy since the same
registers are used. The others are different as registers change -
prepare for that using an empty dkl_pll_write() to be implemented later.

[PATCH 13/22] drm/i915/gen12: add support for reading the timestamp frequency

[Lucas De Marchi]

From: Michel Thierry <michel.thierry@intel.com>

There are no changes with respect to GEN11, which Paulo wrote.

This gets rid of the "Missing switch case in read_timestamp_frequency"
message at boot for Tiger Lake.

This enables the Mesa driver to advertise support for ARB_timer_query,
and thus an OpenGL version higher than 3.2.

[PATCH 16/22] drm/i915/tgl: Implement Wa_1604555607

[Lucas De Marchi]

From: Michel Thierry <michel.thierry@intel.com>

Implement Wa_1604555607 (set the DS pairing timer to 128 cycles).
FF_MODE2 is part of the register state context, that's why it is
implemented here.

[PATCH 18/22] drm/i915/tgl: Define MOCS entries for Tigerlake

[Lucas De Marchi]

From: Tomasz Lis <tomasz.lis@intel.com>

The MOCS table is published as part of bspec, and versioned. Entries
are supposed to never be modified, but new ones can be added. Adding
entries increases table version. The patch includes version 1 entries.

Two of the 3 legacy entries used for gen9 are no longer expected to work.
Although we are changing the gen11 table, those changes are supposed to
be backward compatible since we are only touching previously undefined
entries.

[PATCH 19/22] drm/i915/tgl: Tigerlake only has global MOCS registers

[Lucas De Marchi]

From: Michel Thierry <michel.thierry@intel.com>

Until Icelake, each engine had its own set of 64 MOCS registers. In
order to simplify, Tigerlake moves to only 64 Global MOCS registers,
which are no longer part of the engine context. Since these registers
are now global, they also only need to be initialized once.

These new global MOCS registers are located in the same offset of the
render MOCS register from previous platforms.

From Gen12 onwards, MOCS must specify the target cache (3:2) and LRU
management (5:4) fields and cannot be programmed to 'use the value from
Private PAT', because these fields are no longer part of the PPAT. Also
cacheability control (1:0) field has changed, 00 no longer means 'use
controls from page table', but uncacheable (UC).

[PATCH 22/22] drm/i915/mst: Do not hardcoded the crtcs that encoder can connect

[Lucas De Marchi]

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

Tiger Lake has up to 4 pipes so the mask would need to be 0xf instead of
0x7. Do not hardcode the mask so it allows the fake MST encoders to
connect to all pipes no matter how many the platform has.

Iterating over all pipes to keep consistent with intel_ddi_init().

Why is this marked as reserved? From the looks of things 48-61 should
just be normal entries that userspace can select to get HDC L1$. And
looks like icl already has that stuff. So someone should probably figure
out if Mesa/etc. can make use of the HDC L1$, and if so we should add
the relevant MOCS entries for icl as well.

Here the reserved terminology is indeed misleading. The 48-59 range is a 
"special" range where L1 usage is implicitly enabled by the HW, as there 
is no explicit L1 toggle in the MOCS registers. The reserved here means 
that the range shouldn't be used for "normal" MOCS settings, but SW can 
freely use these entries as needed. Similarly, MOCS 60 and 61 are 
reserved for other special purposes, but are still usable by SW. The 
only entries SW shouldn't touch are 62 and 63.

Regarding ICL, Gen11 HW doesn't have the capability so no new entries 
are required there.

The specs have MOCS 49-51 defined as well.

No, they're not :). They're located in a new range, which overlaps with 
the location where the fault register was previously located and that's 
why the offset of that one has been changed as well. The code does the 
right thing, so only this sentence needs fixing.

the FAULT_TLB_DATA* registers have been moved as well as part of the 
re-org, so maybe we can have a patch that just moves all the offsets and 
then add the global mocs on top?

Should we put this as a comment in the code somewhere? Although I'm not 
sure we have any use for this info since we copy the table straight from 
the specs and we should probably trust it is correct.

For the BITS_PER_TYPE, ok. But for the swapped order, checkpatch doesn't
agree:

8b77abf61be2 (HEAD) drm/i915/tgl: Add hpd interrupt handling
-:117: WARNING:CONSTANT_COMPARISON: Comparisons should place the constant on the right side of the test
#117: FILE: drivers/gpu/drm/i915/i915_irq.c:1852:
+       BUILD_BUG_ON(HPD_NUM_PINS > BITS_PER_TYPE(*pin_mask));

Note: Initially I did with the same order you suggested and had to swap
it while cleaning up the checkpatch warnings.

Checkpatch is stupid. HPD_NUM_PINS is clearly the "variable" we're trying
to check here, not the constant we're checking against.

my brain read it that way, too. Then after reading the warning I
thought: humnn... there's a constant written in stone and one that
depends on the size of that type: maybe I'm wrong and checkpatch is
right. So I changed the order.

Since we both agree prefer HPD_NUM_PINS as a variable, I will
ignore checkpatch here and swap it back.

True.

TGL_DMC_DEBUG_DC5_COUNT and TGL_DMC_DEBUG_DC6_COUNT sounds good?

yep, makes sense. I will change that in the next version.

I don't see a value in the comment exactly because of this reason. I
think the one in the commit message is enough.

humn... it seems they got added later.

I'm not sure anymore if we should update igt so it doesn't expect those
entries to be set to PTE or if we should stop reusing the same table for
ICL and TGL. Spec doesn't mention the compatibility of this table with
gen 11 anymore. Thoughts?

It might be a good idea to find a better word for it than "reserved". 
Not only for this patch, but to be used everywhere, especially the spec.
But that exceeds the scope of this review.

It doesn't sound right to change the implementation decision to keep them
together, only because this allows to keep tests intact.

I don't believe there's a reason to verify undefined entries in IGT.
Sometimes we do want to verify our specific implementation instead of
pure specs compliance; but I don't see a reason for this should be the 
case here.

The existing MOCS entries are supposed to be unchangeable (in the boundary
of specific platform). So the chances of having to split the tables in 
the future are
low (both tables would have to define V2 entries at same indexes, and define
them differently).

Would it make sense to bring this patch in for now for TGL MST, until
that larger series can land?
