There's a mismatch on API: while xe_rtp_process_to_sr() processes
entries until an entry without name, the active tracking with
xe_rtp_process_ctx_enable_active_tracking() needs to use the number of
elements. The number of elements is taken everywhere using ARRAY_SIZE(),
but that will have one entry too many. This leads to the following
warning, as reported by lkp:
drivers/gpu/drm/xe/xe_tuning.c: In function 'xe_tuning_dump':
>> include/drm/drm_print.h:228:31: warning: '%s' directive argument is null [-Wformat-overflow=]
228 | drm_printf((printer), "%.*s" fmt, (indent), "\t\t\t\t\tX", ##__VA_ARGS__)
| ^~~~~~
drivers/gpu/drm/xe/xe_tuning.c:226:17: note: in expansion of macro 'drm_printf_indent'
226 | drm_printf_indent(p, 1, "%s\n", engine_tunings[idx].name);
| ^~~~~~~~~~~~~~~~~
That's because it will still process the last entry when tracking the
active tunings. The same issue exists in the WAs. Change
xe_rtp_process_to_sr() to also take the number of elements so the empty
entry can be removed and the warning should go away. Fixing on the
active-tracking side would more fragile as the it would need a `- 1`
everywhere and continue to use a different approach for number of
elements.
Aside from the warning, it's a non-issue as there would always be enough
bits allocated and the last entry would never be active since
xe_rtp_process_to_sr() stops on the sentinel.

A recommended performance tuning for LNL related to L3 cache flushing
was recently introduced in Bspec. Implement it.
Unlike the other existing tuning settings, we limit this one for LNL
only, since there is no info about whether this would be applicable to
other platforms yet. In the future we can come back and use IP version
ranges if applicable.
v2:
- Fix reference to Bspec. (Sai Teja, Tejas)
- Use correct register name for "Tuning: L3 RW flush all Cache". (Sai
Teja)
- Use SCRATCH3_LBCF (with the underscore) for better readability.
v3:
- Limit setting to LNL only. (Matt)

With exception of "Tuning: L3 cache - media", we are currently applying
recommended performance tuning settings only for the primary GT. Let's
also implement them for the media GT when applicable.
According to our spec, media GT registers CCCHKNREG1 and L3SQCREG* exist
only in Xe2_LPM and their offsets do not match their primary GT
counterparts. Furthermore, the range where CCCHKNREG1 belongs is not
listed as a multicast range on the media GT. As such, we need to have
Xe2_LPM-specific definitions for those registers and apply the setting
only for that specific IP.
Both Xe2_HPM and Xe2_LPM contain STATELESS_COMPRESSION_CTRL and the
offset on the media GT matches the one on the primary one. So we can
simply have a copy of "Tuning: Stateless compression control" for the
media GT.
v2:
- Fix implementation with respect to multicast vs non-multicast
registers. (Matt)
- Add missing XE2LPM_CCCHKNREG1 on second action of "Tuning:
Compression Overfetch - media".
v3:
- STATELESS_COMPRESSION_CTRL on Xe2_HPM is also a multicast register,
do not define a XE2HPM_STATELESS_COMPRESSION_CTRL register. (Tejas)

Add L3SQCREG5 as part of HW recommended settings. The recommended value
in Bspec is 00e0007f. For Xe2-LPG, bits 23:21 don't exist anymore, but
it's confirmed with HW engineers that setting them doesn't do anything.
They still exist on the media GT, Xe2-LPM, but they are already they are
already set as per HW default value. So for Xe2 platform, the only bits
that need to be set are 9:0 since HW's default is 0x1ff and the
recommended value is 0x7f.
Unlike most registers, which have the same relative offset on both
the primary and media GT, this register has a different base offset
on the media GT.
On MTL the register only exists for the primary (graphics) GT, so
there's no need to program it on the media gt. Also, it's part of the
RCS engine's context, so it needs to be added as a LRC workaround.

The selection between hwe and gt is exposed to the outside of rtp, by
the xe_rtp_process() function. However it doesn't make seense from the
caller point of view to pass a hwe and a gt as argument since the gt
should always be the one containing the hwe.
This clarifies the interface by separating the context creation into an
initializer. The initializer then passes the correct value and there
should never be a case with hwe and gt set: when hwe is passed, the gt
is the one containing it. Internally the functions continue receiving
the argument separately.

Now that struct xe_reg and struct xe_reg_mcr are types that can be used
by xe, convert more of the driver to use them. Some notes about the
conversions:
- The RTP tables don't need the MASKED flags anymore in the
actions as that information now comes from the register
definition
- There is no need for the _XE_RTP_REG/_XE_RTP_REG_MCR macros
and the register types on RTP infra: that comes from the
register definitions.
- When declaring the RTP entries, there is no need anymore to
undef XE_REG and friends: the RTP macros deal with removing
the cast where needed due to not being able to use a compound
statement for initialization in the tables
- The index in the reg-sr xarray is the register offset only.
Otherwise we wouldn't catch mistakes about adding both a
MCR-style and normal-style registers. For that, the register
is now also part of the entry, so the options can be compared
to check for compatible entries.
In order to be able to accomplish this, some improvements are needed on
the RTP macros. Change its implementation to concentrate on "pasting a prefix
to each argument" rather than the more general "call any macro for each
argument". Hopefully this will avoid trying to extend this infra and
making it more complex. With the use of tuples for building the
arguments, it's not possible to pass additional register fields and
using xe_reg in the RTP tables.
xe_mmio_* still need to be converted, from u32 to xe_reg, but that is
left for another change.

These should replace the _MMIO() and MCR_REG() from i915, with the goal
of being more extensible, allowing to pass the additional fields for
struct xe_reg and struct xe_reg_mcr. Replace all uses of _MMIO() and
MCR_REG() in xe.
Since the RTP, reg-save-restore and WA infra are not ready to use the
new type, just undef the macro like was done for the i915 types
previously. That conversion will come later.

The defines for the registers were brought over from i915 while
bootstrapping the driver. As xe supports TGL and later only, it doesn't
make sense to keep the GEN* prefixes and suffixes in the registers: TGL

everywhere.
v2:

VSUNIT_CLKGATE2_DIS with the additional "2", so it doesn't clash

In order to avoid mistakes when populating the workarounds, it's good to
be able to test if the entries added are all compatible for a certain
platform. The platform itself is not needed as long as we create fake
devices with enough configuration for the RTP helpers to process the
tables. Common mistakes that can be avoided:
- Entries clashing the bitfields being updated
- Register type being mixed (MCR vs regular / masked vs regular)
- Unexpected errors while adding the reg_sr entry
To test, inject a duplicate entry in gt_was, but with platform == tigerlake
rather than the currenct graphics version check:
{ XE_RTP_NAME("14011059788"),
XE_RTP_RULES(PLATFORM(TIGERLAKE)),
XE_RTP_ACTIONS(SET(GEN10_DFR_RATIO_EN_AND_CHICKEN, DFR_DISABLE))

That is because the same register is being set both by the WAs and the

since that is applicable for more platforms. Also fix the tuning: it
was incorrectly using the MCR version of the register, but that only

Create regs/xe_gt_regs.h file with all the registers and bit
definitions used by the xe driver. Eventually the registers may be
defined in a different way and since xe doesn't supported below gen12,
the number of registers touched is much smaller, so create a new header.
The definitions themselves are direct copy from the
gt/intel_gt_regs.h file, just sorting the registers by address.
Cleaning those up and adhering to a common coding style is left for
later.

LRC tunings were added after the gt ones and didn't add the call
in xe_gt_record_default_lrcs() to process them like is done for
workarounds. Add such a function and call it from
xe_gt_record_default_lrcs().

Just like there is support for multiple rules per entry in an rtp table,
also support multiple actions. This makes it easier to add support for
workarounds that need to change multiple registers. It also makes it
slightly more readable as now the action part resembles the rule part.

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).
The new Xe driver leverages a lot from i915.
As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.
This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
