Add live KUnit coverage for the debug-controlled BO
page-size allocation modes.
The new tests cover forced 2M mode, forced 1G mode,
and mixed mode. They verify that user BO creation applies
the expected NEEDS_* flags, that no unexpected page-size flags are
added in the forced modes, that BO size is rounded as expected, and
that page_alignment matches the selected leaf size.
The mixed-mode test does not assume a strict per-allocation rotation
sequence, since the device-global mixed-mode index may be perturbed by
concurrent BO creation on a live system. Instead,
it validates that each allocation results in
one valid mixed-mode page-size outcome.
Treat transient VRAM allocation failures as skipped test cases so the
tests can run in varying live environments without producing false
failures.
v3
- address review comments
- rework mixed-mode test to avoid assuming strict rotation order
- reword commit message
v4
- skip VRAM-targeted live tests on non-dGFX devices
v5
- advance the mixed-mode index in the test

On multi-tile platforms, we need to probe the hardware for the number

On GMDID-based platforms, the driver needs to probe the hardware by
reading GMDID registers in order to identify the
graphics/media/display IPs that are present in the platform as well as
their stepping values.
Currently, xe_info_init() has such a probing logic, but that task
should be rather responsibility of xe_probe_info(). As such, move it
to the latter.
For pre-GMDID platforms, the IPs are identified via PCI devid and
revid fields, which is arguably also hardware dependent. So do the
same for those platforms.

Functions xe_info_init_early() and xe_info_init() currently probe some
information from the hardware while doing initialization of info
fields. Besides mixing responsibilities, another issue from this
approach is that kunit tests need to implement static stubs for the
probing part.
Let's prepare the ground to ensuring that those functions stop probing
the information from the hardware by creating the necessary framework
for extracting the probing bits out of them. Do that by creating a
new struct type called xe_probed_info and the functions responsible
for populating it.
In upcoming changes, we will gradually refactor the code so that all
info needed by xe_info_init_early() and xe_info_init() that is probed
from the hardware is passed to them via struct xe_probed_info.

Xe must only add registers to the GT whitelist if they are listed in the
"Software Allowlist" section of the bspec. These registers have been
carefully reviewed by the architecture/security teams to ensure that
they are safe to whitelist from a security perspective. The list of
allowed registers changes from platform to platform, and it is not safe
to assume that a register is safe to whitelist on a new platform/IP just
because it was whitelisted on older ones. This means that whitelist
entries in the driver that used undefined upper bounds
(XE_RTP_END_VERSION_UNDEFINED) for their version ranges should always be
considered illegal since they could potentially open unexpected security
holes on future platforms. Add a kunit test to scan the whitelist RTP
table and ensure that all entries have well-defined upper bounds on IP
version ranges.

It is currently possible for a RTP rule, and subsequently a workaround,
to expect contexts that may not be present when the workaround is
applied. For example, the workarounds in the engine_was[] in drm/xe/xe_wa.c
expect an engine entity to be active. Conversely, the gt_was[] is not
depending on an engine entity to implement its workarounds. This kunit
test addition checks the gt_was[] workaround list for any workarounds
with XEP_RTP_ENGINE_CLASS() rules. If a workaround does have one of
these rules, the workaround is then checked for the "FOREACH_ENGINE" flag,
which ensures the workaround is implemented properly.
The result of this test is an expectation failure if a workaround has an
improper XE_RTP_ENGINE_CLASS() rule setup, and aims to prevent future
issues of gt_was workarounds being applied without proper contexts.
The gt_tunings[] RTP table has the same functional layout and
requirements as gt_was[], so it shares the same kunit test function,
minimizing excessive code.

We currently have a mixture of styles for our RTP tables with respect of
how we define the number of entries:
* xe_rtp_process_to_sr() expects to receive the number of entries as
arguments;
* xe_rtp_process() expects the array to have a sentinel at the end of
the array;
* in xe_rtp_test.c, even though xe_rtp_process_to_sr() does not
require a sentinel value, we need to rely on that technique to be
able to count xe_rtp_entry_sr entries because simply using
ARRAY_SIZE() is not possible.
The style used by xe_rtp_process_to_sr() makes it hard to share the
tables with other compilation units (e.g. kunit tests), since the number
of entries is calculated with ARRAY_SIZE(), which is done at compile
time.
Since we use the size of the tables to create some bitmasks, using a
sentinel style doesn't seem great either.
A way to reconcile things into a single style is to have a struct type
that would hold the entries array and the number of entries. Since we
have xe_rtp_entry and xe_rtp_entry_sr, we would have one type for each.
The advantage of the proposed approach is that now we have a nice way to
share the tables directly to kunit tests with information about their
size.

The function rule_matches() short-circuits evaluation of the implicit
conjunctions (each substring of rules not containing OR) and the
explicit disjunctions (implicit conjunctions joined by OR). In other
words:
- in a conjunction, once a rule evaluate to false, we skip to the next
OR (if any) to evaluate the next conjunction;
- in a disjunction, once a conjunction evaluates to true, we return
true and skip evaluating all the remaining rules.
While this behavior results in a correct logical value, due to how the
"OR" short-circuiting is implemented, it has the side-effect that rule
set does not get fully "parsed", allowing incomplete constructs like
(rule1, OR) to evaluate to true when rule1 is true. We should treat
such constructs as invalid and treat them the same way we do for stuff
like (OR, rule1).
As such, update rule_matches() to "parse" the whole rule set, and that
while keeping the short-circuit aspect of evaluation. With that, we can
fix the FIXME test cases that cover that behavior.
v2:
- Do not change short-circuit *evaluation* behavior. (Matt)

With the current implementation, the RTP framework will cause parsing of
the rule set to be interrupted if one rule requires a context item (gt
or hwe) that is missing (i.e. when the value is NULL).
This is arguably a semantic error instead of a syntactic one, meaning
that RTP should not interrupt parsing the rules. With the current
behavior, we would miss detecting other errors that could appear in the
remaining rules and could also prevent valid rules joined by "OR" from
being evaluated.
Make sure that we do not stop parsing the rule set when detecting
missing context and let's add rtp_rules_test_cases to reflect that.
v2:
- Add "missing-context" in the test case names to indicate that those
are about rules that are missing the necessary context. (Matt)
- Rebase: treat the new match type XE_RTP_MATCH_PLATFORM_STEP in the
same way when the platform is missing step information.

While RTP processing evaluates true on the "yes-or" case (i.e. a
conjunction of rules that evaluate to true followed by an "OR" without
the right hand operand), it does not on the "or-yes" one.
Both cases are considered malformed and could be a result of someone
dropping checks deemed not necessary anymore and forgetting to drop the
superfluous "OR". Nevertheless, we should aim for consistency, and
having the "or-yes" case also evaluating to true while also causing a
warning seems reasonable. So let's do that.
The "or-yes" pattern being evaluated to false comes from the fact that
that we unconditionally short-circuit upon finding XE_RTP_MATCH_OR on
the outer loop. We should only do that if the preceding conjunction of
rules evaluated to true (meaning that rcount must be non-zero) and
continue the evaluation otherwise.
Do that and also add extra test cases to validate the short-circuiting
behavior.
Notice that some of the new test cases have a "FIXME" comment, which
comes from the fact that we are unable to detect syntax errors after the
short-circuit point. That is going to be fixed in a follow-up change.

The type struct xe_reg_mcr exists to ensure that the correct API is used
when handling MCR registers. However, for the register save/restore
functionality, the RTP processing always cast the register to a struct
xe_reg and then apply_one_mmio() selects the MMIO API based on the "mcr"
field of the register instance.
This allows the developer to commit mistakes like passing a MCR register
for an RTP action for a GT where the respective register is not MCR; and
vice-versa.
To capture such scenarios, do a sanity check in xe_reg_sr_add() that,
upon an inconsistency:
- "fixes" the register type by favoring what we have in our MCR range
tables instead of what the developer selected for the save/restore
entry;
- raises a notice-level message to inform about the inconsistency.
Note: As a collateral of this change, we need to include MCR
initialization in xe_wa_test.c, otherwise a bunch of test cases end up
failing because xe_gt_mcr_check_reg() will always return false, meaning
that will incorrectly say that a MCR register is not MCR.
v2:
- Downgrade messages to notice level so as not to block CI execution
when inconsistencies are found. (Matt)
- Add missing EXPORT_SYMBOL_IF_KUNIT() calls. (Gustavo)

We've picked the value of TEST_VRAM to match real VRAM size as found
on the machines used by the CI, but that didn't work well on kernels
that have 32-bit resource_size_t. Use smaller value instead.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

There are a few different reg_sr lists managed by the driver for
workarounds/tuning:
- gt->reg_sr
- hwe->reg_sr
- hwe->reg_lrc
The first two are not relevant to SRIOV VFs; a VF KMD does not have
access to the registers that appear on this list and it is the PF KMD's
responsibility to apply such programming on behalf of the entire system.
However the third list contains per-client values that the VF KMD needs
to ensure are incorporated whenever a new LRC is created.
Handling of reg_sr lists comes in two steps: processing an RTP table to
build a reg_sr from the relevant entries, and then applying the contents
of the reg_sr. Skipping the RTP processing (resulting in an empty
reg_sr) or skipping the application of a reg_sr are both valid ways to
avoid having a VF accidentally try to write registers it doesn't have
access to. In commit c19e705ec981 ("drm/xe/vf: Stop applying
save-restore MMIOs if VF") and commit 92a5bd302458 ("drm/xe/vf: Unblock
xe_rtp_process_to_sr for VFs") we adjusted the drivers behavior to
always process the RTP table into a reg_sr and just skipped the
application step. This works fine functionally, but can lead to
confusion during debugging since facilities like the debugfs
'register-save-restore' will still report a bunch of registers that the
VF KMD isn't actually trying to handle. It will also mislead other
upcoming debug changes.
Let's go back to skipping the RTP => reg_sr processing step, but only
for GT / hwe tables this time. This will allow LRC reg_sr handling to
continue to work, but will ensure that gt->reg_sr and hwe->reg_sr remain
empty and that debugfs reporting more accurately reflects the KMD's
behavior.
v2:
- Also skip the hwe processing in hw_engine_setup_default_state() and
xe_reg_whitelist_process_engine().
v3:
- Handle skipping via an additional parameter passed to
xe_rtp_process_to_sr() rather than adding conditions at each
callsite. (Ashutosh)

The number of registers used to express the XeCore mask has some
"special cases" that don't always get inherited by later IP versions so
it's cleaner and simpler to record the numbers in the IP descriptor
rather than adding extra conditions to the standalone get_num_dss_regs()
function.
Note that a minor change here is that we now always treat the number of
registers as 0 for the media GT. Technically a copy of these fuse
registers does exist in the media GT as well (at the usual
0x380000+$offset location), but the value of those is always supposed to
read back as 0 because media GTs never have any XeCores or EUs.
v2:
- Add a kunit assertion to catch descriptors that forget to initialize
either count. (Gustavo)

The G2G KUnit test allocates a compact N×N
matrix sized by gt_count and verifies entries
using dense indices: idx = (j * gt_count) + i
The producer path currently computes idx using
gt->info.id. However, gt->info.id values
are not guaranteed to be contiguous.
For example, with gt_count=2 and IDs {0,3},
this formula produces indices beyond the
allocated range, causing mismatches and
potential out-of-bounds access.
Update the producer to map each GT to a dense
index in [0..gt_count-1] and compute:
idx = (tx_dense * gt_count) + rx_dense
Additionally, introduce an event-based delay
in g2g_test_in_order() to ensure ordering
between sends.

all new importers implement this callback.

clangd reports many "unused header" warnings throughout the Xe driver.
Start working to clean this up by removing unnecessary includes in our
.c files and/or replacing them with explicit includes of other headers
that were previously being included indirectly.
By far the most common offender here was unnecessary inclusion of
xe_gt.h. That likely originates from the early days of xe.ko when
xe_mmio did not exist and all register accesses, including those
unrelated to GTs, were done with GT functions.
There's still a lot of additional #include cleanup that can be done in
the headers themselves; that will come as a followup series.
v2:
- Squash the 79-patch series down to a single patch. (MattB)
