8bfab7cd83 drm/xe/tests: Add helpers for use in live tests
Instead of iterating over available Xe devices within a testcase,
without being able to distinguish potential failures from different
devices on system with many Xe devices, introduce helpers that will
allow to treat each Xe device as a parameter for the testcase like:

static void bar(struct kunit *test)
{
	struct xe_device *xe = test->priv;
	...
}

struct kunit_case foo_live_tests[] = {
	KUNIT_CASE_PARAM(bar, xe_pci_live_device_gen_param),
	{}
};

struct kunit_suite foo_suite = {
	.name = "foo_live",
	.test_cases = foo_live_tests,
	.init = xe_kunit_helper_xe_device_live_test_init,

2b808d6b29 drm/xe/xe2: Introduce identity map for compressed pat for vram
Xe2+ has unified compression (exactly one compression mode/format),
where compression is now controlled via PAT at PTE level.
This simplifies KMD operations, as it can now decompress freely
without concern for the buffer's original compression format—unlike DG2,
which had multiple compression formats and thus required copying the
raw CCS state during VRAM eviction. In addition mixed VRAM and system
memory buffers were not supported with compression enabled.

On Xe2 dGPU compression is still only supported with VRAM, however we
can now support compression with VRAM and system memory buffers,
with GPU access being seamless underneath. So long as when doing
VRAM -> system memory the KMD uses compressed -> uncompressed,
to decompress it. This also allows CPU access to such buffers,
assuming that userspace first decompress the corresponding
pages being accessed.
If the pages are already in system memory then KMD would have already
decompressed them. When restoring such buffers with sysmem -> VRAM
the KMD can't easily know which pages were originally compressed,
so we always use uncompressed -> uncompressed here.
With this it also means we can drop all the raw CCS handling on such
platforms (including needing to allocate extra CCS storage).

In order to support this we now need to have two different identity
mappings for compressed and uncompressed VRAM.
In this patch, we set up the additional identity map for the VRAM with
compressed pat_index. We then select the appropriate mapping during
migration/clear. During eviction (vram->sysmem), we use the mapping
from compressed -> uncompressed. During restore (sysmem->vram), we need
the mapping from uncompressed -> uncompressed.
Therefore, we need to have two different mappings for compressed and
uncompressed vram. We set up an additional identity map for the vram
with compressed pat_index.
We then select the appropriate mapping during migration/clear.

v2: Formatting nits, Updated code to match recent changes in
    xe_migrate_prepare_vm(). (Matt)

v3: Move identity map loop to a helper function. (Matt Brost)

v4: Split helper function in different patch, and
	add asserts and nits. (Matt Brost)

v5: Convert the 2 bool arguments of pte_update_size to flags
	argument (Matt Brost)

v6: Formatting nits (Matt Brost)

The motivation to use Kunit instead of IGT is that, although we can verify
whether the data is zero following bo creation,
we cannot confirm whether the zero value after bo creation is the result of
our clear function or simply because the initial data present was zero.

62742d1266 drm/xe: Normalize bo flags macros
The flags stored in the BO grew over time without following
much a naming pattern. First of all, get rid of the _BIT suffix that was
banned from everywhere else due to the guideline in
drivers/gpu/drm/i915/i915_reg.h that xe kind of follows:

	Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.

Here the flags aren't for a register, but it's good practice to keep it
consistent.

Second divergence on names is the use or not of "CREATE". This is
because most of the flags are passed to xe_bo_create*() family of
functions, changing its behavior. However, since the flags are also
stored in the bo itself and checked elsewhere in the code, it seems
better to just omit the CREATE part.

With those 2 guidelines, all the flags are given the form
XE_BO_FLAG_<FLAG_NAME> with the following commands:

	git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i \
		-e "s/XE_BO_\([_A-Z0-9]*\)_BIT/XE_BO_\1/g" \
		-e 's/XE_BO_CREATE_/XE_BO_FLAG_/g'
	git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i -r \
		-e 's/XE_BO_(DEFER_BACKING|SCANOUT|FIXED_PLACEMENT|PAGETABLE|NEEDS_CPU_ACCESS|NEEDS_UC|INTERNAL_TEST|INTERNAL_64K|GGTT_INVALIDATE)/XE_BO_FLAG_\1/g'

And then the defines in drivers/gpu/drm/xe/xe_bo.h are adjusted to
follow the coding style.

f4fb157cd0 drm/xe/kunit: Add basic tests for GuC context ID Manager
Before we switch-over submission code to use new GuC context ID
Manager, lets add some kunit tests to make sure that ID manager
works as expected.

431547134e drm/xe/mocs: Clarify which GT is being operated on
Switch the MOCS-related debug messages to use a GT-specific logging
function and add ID/type output to the beginning of the MOCS kunit test
to assist with debug when problems arise.

00e9062e8d drm/xe/mocs: Determine MCR separately for primary/media GT in kunit test
Although MOCS registers became multicast in graphics version 12.50 on
the primary GT, this transition did not happen until version 20 on the
media GT.  Considering each GT independently is mostly important for
MTL/ARL where the Xe_LPM+ IP has non-MCR MOCS registers, even though
Xe_LPG IP has MCR registers.

50a9ffe61f drm/xe/mocs: Allow odd number of entries on test
Refactor the mocs/l3cc kunit test to support odd number of entries. This
switches out from the "check the register value" approach to check the
entry value if it makes sense from the register read. This provides an
easier output to reason about and cross check with bspec.

Some code reordering and variable re-use was also done so the 2
functions follow more or less the same logic.

first thing in that function. The kunit test replicates the same check,

689a930b93 drm/xe/tests: Fix printf format specifiers in xe_migrate test
KUNIT_FAIL() is used to fail the xe_migrate test when an error occurs.
However, there's a mismatch in the format specifier: '%li' is used to
log 'err', which is an 'int'.

Use '%i' instead of '%li', and for the case where we're printing an
error pointer, just use '%pe', instead of extracting the error code
manually with PTR_ERR(). (This also results in a nicer output when the
error code is known.)

7425c43c26 drm/xe/migrate: Fix CCS copy for small VRAM copy chunks
Since the migrate code is using the identity map for addressing VRAM,
copy chunks may become as small as 64K if the VRAM resource is fragmented.

However, a chunk size smaller that 1MiB may lead to the *next* chunk's
offset into the CCS metadata backup memory may not be page-aligned, and
the XY_CTRL_SURF_COPY_BLT command can't handle that, and even if it could,
the current code doesn't handle the offset calculaton correctly.

To fix this, make sure we align the size of VRAM copy chunks to 1MiB. If
the remaining data to copy is smaller than that, that's not a problem,
so use the remaining size. If the VRAM copy cunk becomes fragmented due
to the size alignment restriction, don't use the identity map, but instead
emit PTEs into the page-table like we do for system memory.

v2:
- Rebase
v3:
- Future proof somewhat by taking into account the real data size to
  flat CCS metadata size ratio. (Matt Roper)
- Invert a couple of if-statements for better readability.
- Fix support for 4K-granularity VRAM sizes. (Tested on DG1).
v4:
- Fix up code comments
- Fix debug printout format typo.
v5:
- Add a Fixes: tag.

Currently it's not possible to test the WAs for platforms using gmdid
since they don't have the IP information on the descriptor struct. In
order to allow that, add a stub function for read_gmdid() that is
activated when the test executes, replacing the iomap and read of the

Instead of passing as parameter to xe_pci_fake_device_init(), use
test->priv to pass parameters down the call stack. The main advantage is
that then the data is readily available on other functions by using
kunit_get_current_test().

This is a preparation to fix the initialization of fake devices when
they were supposed to be using GMD_ID.

622f709ca6 drm/xe/uapi: Add support for CPU caching mode
Allow userspace to specify the CPU caching mode at object creation.
Modify gem create handler and introduce xe_bo_create_user to replace
xe_bo_create. In a later patch we will support setting the pat_index as
part of vm_bind, where expectation is that the coherency mode extracted
from the pat_index must be least 1way coherent if using cpu_caching=wb.

v2
  - s/smem_caching/smem_cpu_caching/ and
    s/XE_GEM_CACHING/XE_GEM_CPU_CACHING/. (Matt Roper)
  - Drop COH_2WAY and just use COH_NONE + COH_AT_LEAST_1WAY; KMD mostly
    just cares that zeroing/swap-in can't be bypassed with the given
    smem_caching mode. (Matt Roper)
  - Fix broken range check for coh_mode and smem_cpu_caching and also
    don't use constant value, but the already defined macros. (José)
  - Prefer switch statement for smem_cpu_caching -> ttm_caching. (José)
  - Add note in kernel-doc for dgpu and coherency modes for system
    memory. (José)
v3 (José):
  - Make sure to reject coh_mode == 0 for VRAM-only.
  - Also make sure to actually pass along the (start, end) for
    __xe_bo_create_locked.
v4
  - Drop UC caching mode. Can be added back if we need it. (Matt Roper)
  - s/smem_cpu_caching/cpu_caching. Idea is that VRAM is always WC, but
    that is currently implicit and KMD controlled. Make it explicit in
    the uapi with the limitation that it currently must be WC. For VRAM
    + SYS objects userspace must now select WC. (José)
  - Make sure to initialize bo_flags. (José)
v5
  - Make to align with the other uapi and prefix uapi constants with
    DRM_ (José)
v6:
  - Make it clear that zero cpu_caching is only allowed for kernel
    objects. (José)
v7: (Oak)
  - With all the changes from the original design, it looks we can
    further simplify here and drop the explicit coh_mode. We can just
    infer the coh_mode from the cpu_caching. i.e reject cpu_caching=wb +
    coh_none. It's one less thing for userspace to maintain so seems
    worth it.
v8:
  - Make sure to also update the kselftests.

6a024f1bfd drm/xe/bo: support tiered vram allocation for small-bar
Add the new flag XE_BO_NEEDS_CPU_ACCESS, to force allocating in the
mappable part of vram. If no flag is specified we do a topdown
allocation, to limit the chances of stealing the precious mappable part,
if we don't need it. If this is a full-bar system, then this all gets
nooped.

For kernel users, it looks like xe_bo_create_pin_map() is the central
place which users should call if they want CPU access to the object, so
add the flag there.

We still need to plumb this through for userspace allocations. Also it
looks like page-tables are using pin_map(), which is less than ideal. If
we can already use the GPU to do page-table management, then maybe we
should just force that for small-bar.

ee82d2da9c drm/xe: add missing bulk_move reset
It looks like bulk_move is set during object construction, but is only
removed on object close, however in various places we might not yet have
an actual fd to close, like on the error paths for the gem_create ioctl,
and also one internal user for the evict_test_run_gt() selftest. Try to
handle those cases by manually resetting the bulk_move. This should
prevent triggering:

WARNING: CPU: 7 PID: 8252 at drivers/gpu/drm/ttm/ttm_bo.c:327

5a142f9c67 drm/xe/selftests: restart GT after xe_bo_restore_kernel()
Test seems to be failing badly after calling xe_bo_restore_kernel().
Taking a snapshot of the CTB and copying back a potentially old version
seems risky, depending on what might have been inflight. Also it seems
snapshotting the ADS object and copying back results in serious
breakage. Normally when calling xe_bo_restore_kernel() we always fully
restart the GT, which re-intializes such things.  We could potentially
skip saving and restoring such objects in xe_bo_evict_all() however
seems quite fragile not to also restart the GT. Try to do that here by
triggering a GT reset.

2) xe_vma inherits from drm_gpuva
3) xe_vma_op inherits from drm_gpuva_op
4) VM bind operations (MAP, UNMAP, PREFETCH, UNMAP_ALL) call into the

Note that one remaining shortcoming here that will need to be addressed

a5edc7cdb3 drm/xe: Introduce xe_tile

part of that.  On platforms like MTL, there's only a single full GPU
(tile) which has its IP blocks provided by two GTs.  In contrast, a
"multi-tile" platform like PVC is basically multiple complete GPUs
packed behind a single PCI device.

For now, just create xe_tile as a simple wrapper around xe_gt.  The
items in xe_gt that are truly tied to the tile rather than the GT will
be moved in future patches.  Support for multiple GTs per tile (i.e.,
the MTL standalone media case) will also be re-introduced in a future

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.

07fbd1f85d drm/xe: Plumb xe_reg into WAs, rtp, etc
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.

	- 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:

4cc0440229 drm/xe: Add basic unit tests for rtp
Add some basic unit tests for rtp. This is intended to prove the
functionality of the rtp itself, like coalescing entries, rejecting
non-disjoint values, etc.

Contrary to the other tests in xe, this is a unit test to test the
sw-side only, so it can be executed on any machine - it doesn't interact
with the real hardware. Running it produces the following output:

Note that the ERRORs in the kernel log are expected since it's testing
incompatible entries.

v2:
  - Use parameterized table for tests  (Michał Winiarski)
  - Move everything to the xe_rtp_test.ko and only add a few exports to the
    right namespace
  - Add more tests to cover FIELD_SET, CLR, partially true rules, etc

e460410023 drm/xe: Generalize fake device creation
Instead of requiring tests to initialize a fake device an keep it in
sync with xe_pci.c when it's platform-dependent, export a function from
xe_pci.c to be used and piggy back on the device info creation. For
simpler tests that don't need any specific platform and just need a fake
xe device to pass around, xe_pci_fake_device_init_any() can be used.

60d5c6abc2 drm/xe: Use symbol namespace for kunit tests
Instead of simply using EXPORT_SYMBOL() to export the functions needed
in xe.ko to be be called across modules, use EXPORT_SYMBOL_IF_KUNIT()
which will export the symbol under the EXPORTED_FOR_KUNIT_TESTING
namespace.

This avoids accidentally "leaking" these functions and letting them be
called from outside the kunit tests. If these functiosn are accidentally
called from another module, they receive a modpost error like below:

	ERROR: modpost: module XXXXXXX uses symbol
	xe_ccs_migrate_kunit from namespace EXPORTED_FOR_KUNIT_TESTING,
	but does not import it.

11a2407ed5 drm/xe: Stop accepting value in xe_migrate_clear
Although xe_migrate_clear() has a value argument, currently the driver
is only passing 0 at all the places this function is invoked with the
exception the kunit tests are using the parameter to validate this
function with different values.
xe_migrate_clear() is failing on platforms with link copy engines
because xe_migrate_clear() via emit_clear() is using the blitter
instruction XY_FAST_COLOR_BLT to clear the memory. But this instruction
is not supported by link copy engine.
So the solution is to use the alternate instruction MEM_SET when
platform contains link copy engine. But MEM_SET instruction accepts only
8-bit value for setting whereas the value agrument of xe_migrate_clear()
is 32-bit.
So instead of spreading this limitation around all invocations of
xe_migrate_clear() and causing more confusion, it was decided to not
accept any value itself as driver does not really need this currently.

All the kunit tests are adapted as per the new function prototype.

This will be followed by a patch to add support for link copy engines.

dd08ebf6c3 drm/xe: Introduce a new DRM driver for Intel GPUs
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:
