56f1b31f1d drm/i915: Store CS timestamp frequency in Hz
kHz isn't accurate enough for storing the CS timestamp
frequency on some of the platforms. Store the value
in Hz instead.

31a02eb70b drm/i915: Refactor setting dma info to a common helper
DMA_MASK bit values are different for different generations.

This will become more difficult to manage over time with the open
coded usage of different versions of the device.

Fix by:
  disallow setting of dma mask in AGP path (< GEN(5) for i915,
  add dma_mask_size to the device info configuration,
  updating open code call sequence to the latest interface,
  refactoring into a common function for setting the dma segment
  and mask info

10cf8e755a drm/i915: Store cpu_transcoder_mask in device info
We have a bunch of code that would like to know which
CPU transcoders are actually present in the hardware. Rather than
use various ad-hoc methods let's just include a full bitmask in
the device info, alongside pipe_mask.

1883a0a465 drm/i915: Track hw reported context runtime
GPU saves accumulated context runtime (in CS timestamp units) in PPHWSP
which will be useful for us in cases when we are not able to track context
busyness ourselves (like with GuC). Keep a copy of this in struct
intel_context from where it can be easily read even if the context is not
pinned.

v2:
 (Chris)
 * Do not store pphwsp address in intel_context.
 * Log CS wrap-around.
 * Simplify calculation by relying on integer wraparound.
v3:
 * Include total/avg in traces and error state for debugging

0f0f9aeee3 drm/i915: Manipulate DBuf slices properly
Start manipulating DBuf slices as a mask,
but not as a total number, as current approach
doesn't give us full control on all combinations
of slices, which we might need(like enabling S2
only can't enabled by setting enabled_slices=1).

Removed wrong code from intel_get_ddb_size as
it doesn't match to BSpec. For now still just
use DBuf slice until proper algorithm is implemented.

Other minor code refactoring to get prepared
for major DBuf assignment changes landed:
- As now enabled slices contain a mask
  we still need some value which should
  reflect how much DBuf slices are supported
  by the platform, now device info contains
  num_supported_dbuf_slices.
- Removed unneeded assertion as we are now
  manipulating slices in a more proper way.

v2: Start using enabled_slices in dev_priv

v3: "enabled_slices" is now "enabled_dbuf_slices_mask",
    as this now sits in dev_priv independently.

v4: - Fixed debug print formatting to hex(Matt Roper)
    - Optimized dbuf slice updates to be used only
      if slice union is different from current conf(Matt Roper)
    - Fixed some functions to be static(Matt Roper)
    - Created a parameterized version for DBUF_CTL to
      simplify DBuf programming cycle(Matt Roper)
    - Removed unrequred field from GEN10_FEATURES(Matt Roper)

v5: - Removed redundant programming dbuf slices helper(Ville Syrjälä)
    - Started to use parameterized loop for hw readout to get slices
      (Ville Syrjälä)
    - Added back assertion checking amount of DBUF slices enabled
      after DC states 5/6 transition, also added new assertion
      as starting from ICL DMC seems to restore the last DBuf
      power state set, rather than power up all dbuf slices
      as assertion was previously expecting(Ville Syrjälä)

v6: - Now using enum for DBuf slices in this patch (Ville Syrjälä)
    - Removed gen11_assert_dbuf_enabled and put gen9_assert_dbuf_enabled
      back, as we really need to have a single unified assert here
      however currently enabling always slice 1 is enforced by BSpec,
      so we will have to OR enabled slices mask with 1 in order
      to be consistent with BSpec, that way we can unify that
      assertion and against the actual state from the driver, but
      not some hardcoded value.(concluded with Ville)
    - Remove parameterized DBUF_CTL version, to extract it to another
      patch.(Ville Syrjälä)
v7:
    - Removed unneeded hardcoded return value for older gens from
      intel_enabled_dbuf_slices_mask - this now is handled in a
      unified manner since device info anyway returns max dbuf slices
      as 1 for older platforms(Matthew Roper)
    - Now using INTEL_INFO(dev_priv)->num_supported_dbuf_slices instead
      of intel_dbuf_max_slices function as it is trivial(Matthew Roper)

v8: - Fixed icl_dbuf_disable to disable all dbufs still(Ville Syrjälä)

v9: - Renamed _DBUF_CTL_S to DBUF_CTL_S(Ville Syrjälä)
    - Now using power_domain mutex to protect from race condition, which
      can occur because intel_dbuf_slices_update might be running in
      parallel to gen9_dc_off_power_well_enable being called from
      intel_dp_detect for instance, which causes assertion triggered by
      race condition, as gen9_assert_dbuf_enabled might preempt this
      when registers were already updated, while dev_priv was not.

a7a7a0e6eb drm/i915/tgl: Tigerlake only has global MOCS registers
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.

>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).

v2 (Lucas):
    - Move the changes to the fault registers to a separate commit - the
      old ones overlap with the range used by the new global MOCS
      (requested by Daniele)
v3 (Lucas):
    - Clarify comment about setting the unused entries to the same value
      of index 0, that is the invalid entry (requested by Daniele)
    - Move changes to DONE_REG and ERROR_GEN6 to a separate commit
      (requested by Daniele)

0caf625777 drm/i915: Add modular FIA
Some platforms may have Modular FIA. If Modular FIA is used in the SOC,
then Display Driver will access the additional instances of
FIA based on pre-assigned offset in GTTMADDR space.

Each Modular FIA instance has its own IOSF Sideband Port ID
and it houses only 2 Type-C Port. In SOC that has more than
two Type-C Ports, there are multiple instances of Modular FIA.
Gunit will need to use different destination ID when it access
different pair of Type-C Port.

The DFLEXDPSP register has Modular FIA bit starting on Tiger Lake.  If
Modular FIA is used in the SOC, this register bit exists in all the
instances of Modular FIA. IOM FW is required to program only the MF bit
in first FIA instance that houses the Type-C Port 0 and Port 1, for
Display Driver to read from.

v2 (Lucas):
  - Move all accesses to FIA to be contained in intel_tc.c, along with
    display_fia that is now called tc_phy_fia
  - Save the fia instance number on intel_digital_port, so we don't have
    to query if modular FIA is used on every access
v3 (Lucas): Make function static
v4 (Lucas): Move enum phy_fia to the header and use it in
   intel_digital_port (suggested by Ville)
v5 (Lucas): Add comment about the mapping between FIA and TC port
   (suggested by Stuart)

7ef5ef5cde drm/i915: add force_probe module parameter to replace alpha_support
The i915.alpha_support module parameter has caused some confusion along
the way. Add new i915.force_probe parameter to specify PCI IDs of
devices to probe, when the devices are recognized but not automatically
probed by the driver. The name is intended to reflect what the parameter
effectively does, avoiding any overloaded semantics of "alpha" and
"support".

The parameter supports "" to disable, "<pci-id>,[<pci-id>,...]" to
enable force probe for one or more devices, and "*" to enable force
probe for all known devices.

Also add new CONFIG_DRM_I915_FORCE_PROBE config option to replace the
DRM_I915_ALPHA_SUPPORT option. This defaults to "*" if
DRM_I915_ALPHA_SUPPORT=y.

Instead of replacing i915.alpha_support immediately, let the two coexist
for a while, with a deprecation message, for a transition period.

112ed2d31a drm/i915: Move GraphicsTechnology files under gt/
Start partitioning off the code that talks to the hardware (GT) from the
uapi layers and move the device facing code under gt/

One casualty is s/intel_ringbuffer.h/intel_engine.h/ with the plan to
subdivide that header and body further (and split out the submission
code from the ringbuffer and logical context handling). This patch aims
to be simple motion so git can fixup inflight patches with little mess.

805446c834 drm/i915: Introduce concept of a sub-platform
Concept of a sub-platform already exist in our code (like ULX and ULT
platform variants and similar),implemented via the macros which check a
list of device ids to determine a match.

With this patch we consolidate device ids checking into a single function
called during early driver load.

A few low bits in the platform mask are reserved for sub-platform
identification and defined as a per-platform namespace.

At the same time it future proofs the platform_mask handling by preparing
the code for easy extending, and tidies the very verbose WARN strings
generated when IS_PLATFORM macros are embedded into a WARN type
statements.

v2: Fixed IS_SUBPLATFORM. Updated commit msg.
v3: Chris was right, there is an ordering problem.

v4:
 * Catch-up with new sub-platforms.
 * Rebase for RUNTIME_INFO.
 * Drop subplatform mask union tricks and convert platform_mask to an
   array for extensibility.

v5:
 * Fix subplatform check.
 * Protect against forgetting to expand subplatform bits.
 * Remove platform enum tallying.
 * Add subplatform to error state. (Chris)
 * Drop macros and just use static inlines.
 * Remove redundant IRONLAKE_M. (Ville)

v6:
 * Split out Ironlake change.
 * Optimize subplatform check.
 * Use __always_inline. (Lucas)
 * Add platform_mask comment. (Paulo)
 * Pass stored runtime info in error capture. (Chris)

v7:
 * Rebased for new AML ULX device id.
 * Bump platform mask array size for EHL.
 * Stop mentioning device ids in intel_device_subplatform_init by using
   the trick of splitting macros i915_pciids.h. (Jani)
 * AML seems to be either a subplatform of KBL or CFL so express it like
   that.

v8:
 * Use one device id table per subplatform. (Jani)

b2ae318acd drm/i915: Rename HAS_GMCH
First of all GMCH can be considered a feature by itself
since it is a chip present in some platforms that connects

Also with the introduction of display block at device info,

.display.has_gmch_display = 1,

So, let's clean up things a bit and use the standardized
way of has_feature on displays side.

No functional change and no manual interaction to generate
this patch.

It is only:

e4c0d5314d drm/i915: Apply LUT validation checks to platforms more accurately (v3)
Use of the new DRM_COLOR_LUT_NON_DECREASING test was a bit over-zealous;
it doesn't actually need to be applied to the degamma on "bdw-style"
platforms.  Likewise, we overlooked the fact that CHV should have that
test applied to the gamma LUT as well as the degamma LUT.

Rather than adding more complicated platform checking to
intel_color_check(), let's just store the appropriate set of LUT
validation flags for each platform in the intel_device_info structure.

v2:
 - Shuffle around LUT size tests so that the hardware-specific tests
   won't be applied to legacy gamma tables.  (Ville)
 - Add a debug message so that it will be easier to understand why an
   atomic transaction involving incorrectly-sized LUT's got rejected
   by the driver.

v3:
 - Switch size_t's to int's.  (Ville)

Fixes: 85e2d61e49 ("drm/i915: Validate userspace-provided color management LUT's (v4)")

reasonable coverage across all machines that expose a GPU reset method,

74c1e82642 drm/i915: remove palette_offsets from device info in favor of _PICK()
The device info offset arrays for unevenly spaced register offsets is
great for widely used registers. However, the palette registers are only
used in one function, i9xx_load_luts_internal(), and only for GMCH
platforms, wasting device info. Replace palette_offsets with _PICK() in
palette register definition.

While the use of _PICK() does not check for pipe C existence, neither
does the current offset array usage, and leads to bogus address when
pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads
to a sensible register offset, just non-existing on non-CHV. Either way,
this shouldn't happen anyway.

Remove unused old palette macros while at it.

9213e4f544 drm/i915/icl: Store available engine masks in INTEL_INFO
Upcoming GuC code will need to read the fused off engine masks as well,
and will also want to have them as enabled instead of disabled masks.

To consolidate the read-out place we can store them in this fashion inside
INTEL_INFO so they can be easily referenced in the future.

4bdafb9ddf drm/i915: Remove i915.enable_ppgtt override
Now that we are confident in providing full-ppgtt where supported,
remove the ability to override the context isolation.

v2: Remove faked aliasing-ppgtt for testing as it no longer is accepted.
v3: s/USES/HAS/ to match usage and reject attempts to load the module on
old GVT-g setups that do not provide support for full-ppgtt.
v4: Insulate ABI ppGTT values from our internal enum (later plans
involve moving ppGTT depth out of the enum, thus potentially breaking
ABI unless we document the current values).

08e3e21a24 drm/i915: kill resource streamer support
After disabling resource streamer on ICL (due to it actually not
existing there), I got feedback that there have been some experimental
patches for mesa to use RS years ago, but nothing ever landed or shipped
because there was no performance improvement.

This removes it from kernel keeping the uapi defines around for
compatibility.

v2: - re-add the inadvertent removal of CTX_CTRL_INHIBIT_SYN_CTX_SWITCH
    - don't bother trying to document removed params on uapi header:
      applications should know that from the query.
      (from Chris)

v3: - disable CTX_CTRL_RS_CTX_ENABLE istead of removing it
    - reword commit message after Daniele confirmed no performance
      regression on his machine
    - reword commit message to make clear RS is being removed due to
      never been used
v4: - move I915_EXEC_RESOURCE_STREAMER to __I915_EXEC_ILLEGAL_FLAGS so
      the check on ioctl() is made much earlier by
      i915_gem_check_execbuffer() (suggested by Tvrtko)

900ccf30f9 drm/i915: Only force GGTT coherency w/a on required chipsets
Not all chipsets have an internal buffer delaying the visibility of
writes via the GGTT being visible by other physical paths, but we use a
very heavy workaround for all. We only need to apply that workarounds to
the chipsets we know suffer from the delay and the resulting coherency
issue.

Similarly, the same inconsistent coherency fouls up our ABI promise that
a write into a mmap_gtt is immediately visible to others. Since the HW
has made that a lie, let userspace know when that contract is broken.
(Not that userspace would want to use mmap_gtt on those chipsets for
other performance reasons...)

8b5eb5e2b5 drm/i915/icl: Added ICL 11 slice, subslice and EU fuse detection
This patch adds support to detect ICL, slice, subslice and EU fuse
settings.

Add addresses for ICL 11 slice, subslice and EU fuses registers.
These register addresses are the same as previous platforms but the
format and / or the meaning of the information is different. Therefore
Gen11 defines for these registers are added.

Bspec: 9731
Bspec: 20643
Bspec: 20673

v2: Update fusing information storage after introducing the new query
    uAPI (Lionel)

v3 (Oscar):
  - The maximum number of slices in ICL 11 is 1
  - The subslice disable fuse can potentially store information in
    all bits
  - GEN_MAX_SUBSLICES has to be increased to 8
  - Don't trust the slice enabled fuse outside the max number of
    expected slices
  - Indentation fix and some reordering and renaming of local
    variables

v4: Use single space after Cc tag
