The x86-only KVM_CAP_TRIPLE_FAULT_EVENT was (appropriately) renamed to
KVM_CAP_X86_TRIPLE_FAULT_EVENT when the patches were applied, but the
docs and selftests got left behind. Fix them.

Update 'ret' with the return value of _kvm_device_access() prior to
asserting that ret is non-zero. In the current code base, the flaw is
benign as 'ret' is guaranteed to be -EBUSY from the previous run_vcpu(),
which also means that errno==EBUSY prior to _kvm_device_access(), thus
the "errno == EFAULT" part of the assert means that a false negative is
impossible (unless the kernel is being truly mean and spuriously setting
errno=EFAULT while returning success).

When iterating over vCPUs, invoke access_v3_redist_reg() on the "current"
vCPU instead of vCPU0, which is presumably what was intended by iterating
over all vCPUs.

Drop the @perm param from vm_create() and always open VM file descriptors
with O_RDWR. There's no legitimate use case for other permissions, and
if a selftest wants to do oddball negative testing it can open code the
necessary bits instead of forcing a bunch of tests to provide useless
information.

Add a second underscore to inner ioctl() helpers to better align with
commonly accepted kernel coding style, and to allow using a single
underscore variant in the future for macro shenanigans.

Make vcpu_ioctl() a macro wrapper and pretty the _name_ of the ioctl on
failure instead of the number. Add inner macros to allow handling cases
where the name of the ioctl needs to be resolved higher up the stack, and
to allow using the formatting for non-ioctl syscalls without being
technically wrong.
Deliberately do not use __stringify(), as that will expand the ioctl all
the way down to its numerical sequence, again the intent is to print the
name of the macro.

Drop @mode from vm_create() and have it use VM_MODE_DEFAULT. Add and use
an inner helper, __vm_create(), to service the handful of tests that want
something other than VM_MODE_DEFAULT.

Split vcpu_nested_state_set() into a wrapper that asserts, and an inner
helper that does not. Passing a bool is all kinds of awful as it's
unintuitive for readers and requires returning an 'int' from a function
that for most users can never return anything other than "success".

Use the recently introduced vCPU-specific ioctl() helpers instead of
open coding calls to ioctl() just to pretty print the ioctl name.

failures don't need to open code the ioctl() call.

Use vcpu_access_device_attr() in arm's arch_timer test instead of
manually retrieving the vCPU's fd. This will allow dropping vcpu_get_fd()
in a future patch.

Drop vcpu_get_fd(), it no longer has any users, and really should not
exist as the framework has failed if tests need to manually operate on
a vCPU fd.

Make vm_ioctl() a macro wrapper and print the _name_ of the ioctl on
failure instead of the number.
Deliberately do not use __stringify(), as that will expand the ioctl all
the way down to its numerical sequence. Again the intent is to print the
name of the macro.

Use the recently introduced VM-specific ioctl() helpers instead of open
coding calls to ioctl() just to pretty print the ioctl name. Keep a few
open coded assertions that provide additional info.

Make kvm_ioctl() a macro wrapper and print the _name_ of the ioctl on
failure instead of the number.
Deliberately do not use __stringify(), as that will expand the ioctl all
the way down to its numerical sequence, again the intent is to print the
name of the macro.

x86 and only used internally.

Fold kvm_util_internal.h into kvm_util_base.h, i.e. make all KVM utility
stuff "public". Hiding struct implementations from tests has been a
massive failure, as it has led to pointless and poorly named wrappers,
unnecessarily opaque code, etc...
Not to mention that the approach was a complete failure as evidenced by
the non-zero number of tests that were including kvm_util_internal.h.

Use the KVM_IOCTL_ERROR() macro to generate error messages for a handful
of one-off arm64 ioctls. The calls in question are made without an
associated struct kvm_vm/kvm_vcpu as they are used to configure those
structs, i.e. can't be easily converted to e.g. vcpu_ioctl().

Remove the two calls that pass @test=true to kvm_create_device() and drop
the @test param entirely. The two removed calls don't check the return
value of kvm_create_device(), so other than verifying KVM doesn't explode,
which is extremely unlikely given that the non-test variant was _just_
called, they are pointless and provide no validation coverage.

Move KVM_CREATE_DEVICE_TEST to its own helper, identifying "real" versus
"test" device creation based on a hardcoded boolean buried in the middle
of a param list is painful for readers.

Rename kvm_device_check_attr() and its variants to kvm_has_device_attr()
to be consistent with the ioctl names and with other helpers in the KVM
selftests framework.

Drop 'int' returns from *_device_has_attr() helpers that assert the
return is '0', there's no point in returning '0' and "requiring" the
caller to perform a redundant assertion.

Split the get/set device_attr helpers instead of using a boolean param to
select between get and set. Duplicating upper level wrappers is a very,
very small price to pay for improved readability, and having constant (at
compile time) inputs will allow the selftests framework to sanity check
ioctl() invocations.

Add a backpointer to 'struct vcpu' so that tests can get at the owning
VM when passing around a vCPU object. Long term, this will be little
more than a nice-to-have feature, but in the short term it is a critical
step toward purging the VM+vcpu_id ioctl mess without introducing even
more churn.

Cache the list of MSRs to save restore, mostly to justify not freeing the
list in the caller, which simplifies consumption of the list.
Opportunistically move the XSS test's so called is_supported_msr() to
common code as kvm_msr_is_in_save_restore_list(). The XSS is "supported"
by KVM, it's simply not in the save/restore list because KVM doesn't yet
allow a non-zero value.

Assert that KVM_SET_MSRS returns '0' or '1' when setting XSS to a
non-zero value. The ioctl() itself should "succeed", its only the
setting of the XSS MSR that should fail/fault.

Consolidate the helper for retrieving the list of save/restore MSRs and
the list of feature MSRs, and use the common helpers in the related
get_msr_index_features test. Switching to the common helpers eliminates
the testcase that KVM returns the same -E2BIG result if the input number
of MSRs is '1' versus '0', but considered that testcase isn't very
interesting, e.g. '0' and '1' are equally arbitrary, and certainly not
worth the additional code.

Move the get/set part of the MP_STATE and GUEST_DEBUG helpers to the end
to align with the many other ioctl() wrappers/helpers. Note, this is not
an endorsement of the predominant style, the goal is purely to provide
consistency in the selftests.

Yep. I wish I could say I was cleverly justifying use of macro magic, but it was
just a copy+paste goof.

Add VM creation helpers to expose/return 'struct vcpu' so that tests
don't have to hardcode a VCPU_ID or make assumptions about what vCPU ID
is used by the framework just to retrieve a vCPU the test created.

Move the call to vm_adjust_num_guest_pages() from vm_create_with_vcpus()
down into vm_create_without_vcpus(). This will allow a future patch to
make the "w/o vCPUs" variant the common inner helper, e.g. so that the
"with_vcpus" helper calls the "without_vcpus" helper, instead of having
them be separate paths.

Ouch. Very nice catch! Lucky for me, the resulting conflicts later in the series
are obvious and straightfoward.

Use vm_create_without_vcpus() in set_boot_cpu_id instead of open coding
the equivlant now that the "without_vcpus" variant does
vm_adjust_num_guest_pages().

Heh, and I managed to carry that to the end of the series. At least I'm consistent?

Rename vm_create() to vm_create_barebones() and drop the @phys_pages
param. Pass '0' for the number of pages even though some callers pass
'DEFAULT_GUEST_PHY_PAGES', as the intent behind creating truly barebones
VMs is purely to create a VM, i.e. there aren't vCPUs, there's no guest
code loaded, etc..., and so there is nothing that will ever need or
consume guest memory.
Freeing up the name vm_create() will allow using the name for an inner
helper to the other VM creators, which need a "full" VM.
Opportunisticaly rewrite the function comment for addr_gpa2alias() to
focus on what the _function_ does, not what its _sole caller_ does.

Rename vm_create_without_vcpus() to vm_create() so that it's not
misconstrued as helper that creates a VM that can never have vCPUs, as
opposed to a helper that "just" creates a VM without vCPUs added at time
zero.

Add ____vm_create() to be the innermost helper, and turn vm_create() into
a wrapper the specifies VM_MODE_DEFAULT. Most of the vm_create() callers
just want the default mode, or more accurately, don't care about the mode.

I don't [overly] mind the "____helperhelper" naming style, but in this
case wouldn't __vm_create_barebones() also be a reasonable name?

I don't love the four underscores, but I want to use the "barebones" name only for
cases where the intent is to truly create a barebones VM, i.e. I want to avoid the
common path taking a dependency on "barebones".

Rename xapic_state_test's kvm_vcpu struct to xapic_vcpu to avoid a
collision when the common 'struct vcpu' is renamed to 'struct kvm_vcpu'
in a future patch.

Rename the "state" field of 'struct vcpu' to "run". KVM calls it "run",
the struct name is "kvm_run", etc...

Rename 'struct vcpu' to 'struct kvm_vcpu' to align with 'struct kvm_vm'
in the selftest, and to give readers a hint that the struct is specific
to KVM.

I'm not completely sold on this change. I don't mind that the selftest
vcpu struct isn't named the same as the KVM vcpu struct, since they're
different structs. I also don't mind avoiding 'kvm_' prefixes in "KVM
selftests" (indeed I wonder if we really need the kvm_ prefix for the
vm struct). If we do need prefixes for the kvm selftest framework
code to avoid collisions with test code, then maybe we should invent
something else, rather than use the somewhat ambiguous 'kvm', which
could also collide with stuff in the kvm uapi.
Thanks,
drew

I don't care about about matching KVM's internal naming exactly, but I do care
about not having a bare "vcpu", it makes searching for usage a pain because it's
impossible to differentiate between instances of the struct and variables of the
same name without additional qualifiers.

Same as above, "struct vm *vm" will drive me bonkers :-)

Potential collisions with the KVM uAPI is a feature of sorts, e.g. tests shouldn't
be redefining kvm_* structures (I'd prefer _tests_ not use kvm_* at all, and only
use kvm_* in the library), and I gotta imagine KVM would break at least one real
world userspace if it defined "kvm_vcpu".
That said, I don't have a super strong preference for kvm_ versus something else,
though I think it will be difficult to come up with something that's unique,
intuitive, and doesn't look like a typo.

Maybe just abbreviated "Kvm Selftests", i.e. 'ks_'? I won't harp on this
any longer though, so if that doesn't look good, then we can proceed with
'kvm_'.

ks_ was the best I could come up with too. But looking at it in code, I find it
more distracting than helpful. It's kind of like the uncanny valley effect, where
ks_ *just* close enough to kvm_ that it makes me think something is wrong.

Return the created vCPU from vm_vcpu_add() so that callers don't need to
manually retrieve the vCPU that was just added. Opportunistically drop
the "heavy" function comment, it adds a lot of lines of "code" but not
much value, e.g. it's pretty obvious that @vm is a virtual machine...

I agree and would like to see all the heavy function comments reduced.
Maybe you do that somewhere in next 100 patches :-)

Convert memslot_perf_test to use __vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
This is the first of many, many steps towards eliminating VCPU_ID from
all KVM selftests, and towards eventually purging the VM+vcpu_id mess.

Convert xss_msr_test to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this
is a "functional" change in the sense that the test now creates a vCPU
with vcpu_id==0 instead of vcpu_id==1. The non-zero VCPU_ID was 100%
arbitrary and added little to no validation coverage. If testing
non-zero vCPU IDs is desirable for generic tests, that can be done in the
future by tweaking the VM creation helpers.

Convert vmx_preemption_timer_test to use vm_create_with_one_vcpu() and
pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
Note, this is a "functional" change in the sense that the test now
creates a vCPU with vcpu_id==0 instead of vcpu_id==5. The non-zero
VCPU_ID was 100% arbitrary and added little to no validation coverage.
If testing non-zero vCPU IDs is desirable for generic tests, that can be
done in the future by tweaking the VM creation helpers.
Opportunistically use vcpu_run() instead of _vcpu_run(), the test expects
KVM_RUN to succeed.

Convert vmx_tsc_adjust_test to use vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
Note, this is a "functional" change in the sense that the test now
creates a vCPU with vcpu_id==0 instead of vcpu_id==5. The non-zero
VCPU_ID was 100% arbitrary and added little to no validation coverage.
If testing non-zero vCPU IDs is desirable for generic tests, that can be
done in the future by tweaking the VM creation helpers.

Convert pmu_event_filter_test to use vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
Rename run_vm_to_sync() to run_vcpu_to_sync() accordingly.

Convert smm_test to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this
is a "functional" change in the sense that the test now creates a vCPU
with vcpu_id==0 instead of vcpu_id==1. The non-zero VCPU_ID was 100%
arbitrary and added little to no validation coverage. If testing
non-zero vCPU IDs is desirable for generic tests, that can be done in the
future by tweaking the VM creation helpers.
Opportunistically use vcpu_run() instead of _vcpu_run(), the test expects
KVM_RUN to succeed.

Convert state_test to use vm_create_with_one_vcpu() and
vm_recreate_with_one_vcpu(), and pass around a 'struct kvm_vcpu' object
instead of using a global VCPU_ID. Note, this is a "functional" change
in the sense that the test now creates a vCPU with vcpu_id==0 instead of
vcpu_id==5. The non-zero VCPU_ID was 100% arbitrary and added little to
no validation coverage. If testing non-zero vCPU IDs is desirable for
generic tests, that can be done in the future by tweaking the VM creation
helpers.
Opportunistically use vcpu_run() instead of _vcpu_run(), the test expects
KVM_RUN to succeed.

Convert svm_int_ctl_test to use vm_create_with_one_vcpu() and pass around
a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
Opportunistically make the "vm" variable a local function variable, there
are no users outside of main().

Convert kvm_pv_test to use vm_create_with_one_vcpu() and pass arounda
'struct kvm_vcpu' object instead of using a global VCPU_ID.
Opportunistically use vcpu_run() instead of _vcpu_run() with an open
coded assert that KVM_RUN succeeded.

Convert set_sregs_test to use vm_create_with_one_vcpu() and pass around
a 'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this
is a "functional" change in the sense that the test now creates a vCPU
with vcpu_id==0 instead of vcpu_id==5. The non-zero VCPU_ID was 100%
arbitrary and added little to no validation coverage. If testing
non-zero vCPU IDs is desirable for generic tests, that can be
done in the future by tweaking the VM creation helpers.

Convert vmx_dirty_log_test to use vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
Note, this is a "functional" change in the sense that the test now
creates a vCPU with vcpu_id==0 instead of vcpu_id==1. The non-zero
VCPU_ID was 100% arbitrary and added little to no validation coverage.
If testing non-zero vCPU IDs is desirable for generic tests, that can be
done in the future by tweaking the VM creation helpers.

Convert userspace_msr_exit_test to use vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
Note, this is a "functional" change in the sense that the test now
creates a vCPU with vcpu_id==0 instead of vcpu_id==1. The non-zero
VCPU_ID was 100% arbitrary and added little to no validation coverage.
If testing non-zero vCPU IDs is desirable for generic tests, that can be
done in the future by tweaking the VM creation helpers.
Opportunistically use vcpu_run() instead of _vcpu_run() with an open
coded assert that KVM_RUN succeeded. Fix minor coding style violations
too.

Convert kvm_clock_test to use vm_create_with_one_vcpu() and pass around a

Opportunistically use vcpu_run() instead of _vcpu_run() with an open
coded assert that KVM_RUN succeeded.

Convert hyperv_svm_test to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this is
a "functional" change in the sense that the test now creates a vCPU with
vcpu_id==0 instead of vcpu_id==1. The non-zero VCPU_ID was 100% arbitrary
and added little to no validation coverage. If testing non-zero vCPU IDs
is desirable for generic tests, that can be done in the future by tweaking
the VM creation helpers.
Opportunistically use vcpu_run() instead of _vcpu_run(), the test expects
KVM_RUN to succeed.

Convert hyperv_features to use vm_create_with_one_vcpu() and pass around
a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
Opportunistically use vcpu_run() instead of _vcpu_run() with an open
coded assert that KVM_RUN succeeded.

Convert evmcs_test to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this is
a "functional" change in the sense that the test now creates a vCPU with
vcpu_id==0 instead of vcpu_id==5. The non-zero VCPU_ID was 100% arbitrary
and added little to no validation coverage. If testing non-zero vCPU IDs
is desirable for generic tests, that can be done in the future by tweaking
the VM creation helpers.
Opportunistically use vcpu_run() instead of _vcpu_run(), the test expects
KVM_RUN to succeed.

Convert emulator_error_test to use vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID. Note,
this is a "functional" change in the sense that the test now creates a vCPU
with vcpu_id==0 instead of vcpu_id==5. The non-zero VCPU_ID was 100%
arbitrary and added little to no validation coverage. If testing non-zero
vCPU IDs is desirable for generic tests, that can be done in the future by
tweaking the VM creation helpers.
Opportunistically use vcpu_run() instead of _vcpu_run() with an open
coded assert that KVM_RUN succeeded.

Convert debug_regs to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID.
Opportunstically drop the CLEAR_DEBUG/APPLY_DEBUG macros as they only
obfuscate the code, e.g. operating on local variables not "passed" to the
macro is all kinds of confusing.

Replace MOVE_RIP+SET_RIP with a proper helper, vcpu_skip_insn(), that is
more descriptive, doesn't subtly access local variables, and provides
type safety.

Convert cr4_cpuid_sync_test to use vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID. Note,
this is a "functional" change in the sense that the test now creates a vCPU
with vcpu_id==0 instead of vcpu_id==1. The non-zero VCPU_ID was 100%
arbitrary and added little to no validation coverage. If testing non-zero
vCPU IDs is desirable for generic tests, that can be done in the future by
tweaking the VM creation helpers.
Opportunistically use vcpu_run() instead of _vcpu_run() with an open
coded assert that KVM_RUN succeeded.

Opportunistically make the "vm" variable local, it is unused outside of

Convert xen_shinfo_test to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this is
a "functional" change in the sense that the test now creates a vCPU with
vcpu_id==0 instead of vcpu_id==5. The non-zero VCPU_ID was 100% arbitrary
and added little to no validation coverage. If testing non-zero vCPU IDs
is desirable for generic tests, that can be done in the future by tweaking
the VM creation helpers.

Convert dirty_log_test to pass around a 'struct kvm_vcpu' object instead
of using a global VCPU_ID. Note, this is a "functional" change in the
sense that the test now creates a vCPU with vcpu_id==0 instead of
vcpu_id==5. The non-zero VCPU_ID was 100% arbitrary and added little to
no validation coverage. If testing non-zero vCPU IDs is desirable for
generic tests, that can be done in the future by tweaking the VM creation
helpers.
The test still hardcodes usage of vcpu_id==0, but only for a few lines.
That wart will be removed in the not-too-distant future.

Track the added 'struct kvm_vcpu' object in tsc_scaling_sync instead of
relying purely on the VM + vcpu_id combination. Ideally, the test
wouldn't need to manually manage vCPUs, but the need to invoke a per-VM
ioctl before creating vCPUs is not handled by the selftests framework,
at least not yet...

The two changes above show that this file had some space vs. tab issues.
I just checked and these two lines weren't the only ones, so I guess we
can add cleaning up whitespace of x86_64/tsc_scaling_sync.c to the rainy
day TODO.

Convert vgic_irq to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of passing around a vCPU ID (which is
always the global VCPU_ID...).
Opportunstically align the indentation for multiple functions'
parameters.

An "unrestricted guest" is an VMX-only concept, move the relevant helper
to x86-64 code. Assume most readers can correctly convert underscores to
spaces and oppurtunistically trim the function comment.

Add "arch" into the name of utility functions that are declared in common
code, but (surprise!) have arch-specific implementations. Shuffle code
around so that all such helpers' declarations are bundled together.

Return the created 'struct kvm_vcpu' object from vm_vcpu_add_default(),
which cleans up a few tests and will eventually allow removing vcpu_get()
entirely.
Opportunistically rename @vcpuid to @vcpu_id to follow preferred kernel
style.

Rework set_boot_cpu_id to pass around 'struct kvm_vcpu' objects instead
of relying on global VCPU_IDs. The test is still ugly, but that's
unavoidable since the point of the test is to verify that KVM correctly
assigns VCPU_ID==0 to be the BSP by default. This is literally one of
two KVM selftests that legitimately needs to care about the exact vCPU
IDs of the vCPUs it creates.

Pass around 'struct kvm_vcpu' objects in psci_test instead of relying on
global VCPU_IDs. Ideally, the test wouldn't have to manually create
vCPUs and thus care about vCPU IDs, but it's not the end of the world and
avoiding that behavior isn't guaranteed to be a net positive (an attempt
at macro shenanigans did not go very well).

Add a VM creator that "returns" the created vCPUs by filling the provided

Use a combination of vm_create(), vm_create_with_vcpus(), and
vm_vcpu_add() to convert vgic_init from vm_create_default_with_vcpus(),
and away from referncing vCPUs by ID.
Thus continues the march toward total annihilation of "default" helpers.

Rework vcpu_{g,s}et_reg() to provide the APIs that tests actually want to
use, and drop the three "one-off" implementations that cropped up due to
the poor API.
Ignore the handful of direct KVM_{G,S}ET_ONE_REG calls that don't fit the
APIs for one reason or another.
No functional change intended.

Sync the next stage using the VM before said VM is potentially freed by
the TEST_STAGE_HVC_IFACE_FEAT_DISABLED stage.
Opportunistically take a double pointer in anticipation of also having to
set the new vCPU pointer once the test stops hardcoding '0' everywhere.

Use a combination of vm_create(), vm_create_with_vcpus(), and
vm_vcpu_add() to convert vgic_init from vm_create_default_with_vcpus(),
and away from referncing vCPUs by ID.
Thus continues the march toward total annihilation of "default" helpers.

Convert vm_create_with_one_vcpu to use vm_create_with_vcpus() and pass
around 'struct kvm_vcpu' objects instead of passing around vCPU IDs.
Don't bother with macros for the HALTER versus SENDER indices, the vast
majority of references don't differentiate between the vCPU roles, and
the code that does either has a comment or an explicit reference to the
role, e.g. to halter_guest_code() or sender_guest_code().

Convert sync_regs_test to use vm_create_with_vcpus() and pass around a
'struct kvm_vcpu' object instead of passing around vCPU IDs. Note, this
is a "functional" change in the sense that the test now creates a vCPU
with vcpu_id==0 instead of vcpu_id==5. The non-zero VCPU_ID was 100%
arbitrary and added little to no validation coverage. If testing
non-zero vCPU IDs is desirable for generic tests, that can be done in the
future by tweaking the VM creation helpers.

Pass around a 'struct kvm_vcpu' object in the "resets" test instead of
referencing the vCPU by the global VCPU_ID. Rename the #define for the
vCPU's ID to ARBITRARY_NON_ZERO_VCPU_ID to make it more obvious that (a)
the value matters but (b) is otherwise arbitrary.

Pass around a 'struct kvm_vcpu' object instead of a vCPU ID in s390's
memop test. Pass NULL for the vCPU instead of a magic '-1' ID to
indicate that an ioctl/test should be done at VM scope.
Rename "struct test_vcpu vcpu" to "struct test_info info" in order to
avoid naming collisions (this is the bulk of the diff :-( ).

Convert diag318_test_handler to use vm_create_with_vcpus() and pass around a
'struct kvm_vcpu' object instead of passing around vCPU IDs. Note, this is
a "functional" change in the sense that the test now creates a vCPU with
vcpu_id==0 instead of vcpu_id==6. The non-zero VCPU_ID was 100% arbitrary
and added little to no validation coverage. If testing non-zero vCPU IDs
is desirable for generic tests, that can be done in the future by tweaking
the VM creation helpers.

Use vm_create() instead of vm_create_default_with_vcpus() in
tsc_scaling_sync. The existing call doesn't create any vCPUs, and the
guest_code() entry point is set when vm_vcpu_add_default() is invoked.

Drop all vm_create_default*() helpers, the "default" naming turned out to
terrible as wasn't extensible (hard to have multiple defaults), was a lie
(half the settings were default, half weren't), and failed to capture
relationships between helpers, e.g. compared with the kernel's standard
underscores pattern.

Drop the @vcpuids parameter from VM creators now that there are no users.
Allowing tests to specify IDs was a gigantic mistake as it resulted in
tests with arbitrary and ultimately meaningless IDs that differed only
because the author used test X intead of test Y as the source for
copy+paste (the de facto standard way to create a KVM selftest).
Except for literally two tests, x86's set_boot_cpu_id and s390's resets,
tests do not and should not care about the vCPU ID.

Reference vCPUs by their 'struct kvm_vcpu' object in kvm_page_table_test
instead of by their ID. This moves selftests one step closer towards
taking a 'struct kvm_vcpu *' instead of VM+vcpu_id for vCPU helpers.

The expression for the index should be 'i * max_vcpu + j'. The swapped
i,j usage isn't causing problems now because
DEFAULT_NUM_VM == DEFAULT_NUM_VCPU, but that could change.

It's better to be lucky than good?

Track the vCPU's 'struct kvm_vcpu' object in get-reg-list instead of
hardcoding '0' everywhere.

In preparation for taking a vCPU pointer in vCPU-scoped functions, grab
the vCPU(s) created by __vm_vcpu_add() and use the ID from the vCPU
object instead of hardcoding the ID in ioctl() invocations.
Rename init1/init2 => init0/init1 to avoid having odd/confusing code
where vcpu0 consumes init1 and vcpu1 consumes init2.
Note, this change could easily be done when the functions are converted
in the future, and/or the vcpu{0,1} vs. init{1,2} discrepancy could be
ignored, but then there would be no opportunity to poke fun at the
1-based counting scheme.

Track vCPUs by their 'struct kvm_vcpu' object, and stop assuming that a
vCPU's ID is the same as its index when referencing a vCPU's metadata.

Require the caller of __vm_create_with_vcpus() to provide a non-NULL
array of vCPUs now that all callers do so. It's extremely unlikely a
test will have a legitimate use case for creating a VM with vCPUs without
wanting to do something with those vCPUs, and if there is such a use case,
requiring that one-off test to provide a dummy array is a minor
annoyance.

Take a vCPU directly instead of a VM+vcpu pair in all vCPU-scoped helpers
and ioctls.

Drop vcpu_get() and rename vcpu_find() to vcpu_exists() to make it that
much harder for a test to give meaning to a vCPU ID. I.e. force tests to
capture a vCPU when the vCPU is created.

now that tests can simply reference the variable directly.

All callers of __vm_create_with_vcpus() pass DEFAULT_GUEST_PHY_PAGES for
@slot_mem_pages; drop the param and just hardcode the "default" as the
base number of pages for slot0.

Drop @num_percpu_pages from __vm_create_with_vcpus(), all callers pass
'0' and there's unlikely to be a test that allocates just enough memory
that it needs a per-CPU allocation, but not so much that it won't just do
its own memory management.

Handle all memslot0 size adjustments in __vm_create(). Currently, the
adjustments reside in __vm_create_with_vcpus(), which means tests that
call vm_create() or __vm_create() directly are left to their own devices.
Some tests just pass DEFAULT_GUEST_PHY_PAGES and don't bother with any
adjustments, while others mimic the per-vCPU calculations.
For vm_create(), and thus __vm_create(), take the number of vCPUs that
will be runnable to calculate that number of per-vCPU pages needed for
memslot0. To give readers a hint that neither vm_create() nor
__vm_create() create vCPUs, name the parameter @nr_runnable_vcpus instead
of @nr_vcpus. That also gives readers a hint as to why tests that create
larger numbers of vCPUs but never actually run those vCPUs can skip
straight to the vm_create_barebones() variant.

We should use 'mode' here which means we need to pass it to this helper

Use vm->max_gfn to compute the highest gpa in vmx_apic_access_test, and
blindly trust that the highest gfn/gpa will be well above the memory
carved out for memslot0. The existing check is beyond paranoid; KVM
doesn't support CPUs with host.MAXPHYADDR < 32, and the selftests are all
kinds of hosed if memslot0 overlaps the local xAPIC, which resides above
"lower" (below 4gb) DRAM.

Remove DEFAULT_GUEST_PHY_PAGES and open code the magic number (with a
comment) in vm_nr_pages_required(). Exposing DEFAULT_GUEST_PHY_PAGES to
tests was a symptom of the VM creation APIs not cleanly supporting tests
that create runnable vCPUs, but can't do so immediately. Now that tests
don't have to manually compute the amount of memory needed for basic
operation, make it harder for tests to do things that should be handled
by the framework, i.e. force developers to improve the framework instead
of hacking around flaws in individual tests.

Return an 'unsigned int' instead of a signed 'int' from kvm_check_cap(),
to make it more obvious that kvm_check_cap() can never return a negative
value due to its assertion that the return is ">= 0".

Add kvm_has_cap() to wrap kvm_check_cap() and return a bool for the use
cases where the caller only wants check if a capability is supported,
i.e. doesn't care about the value beyond whether or not it's non-zero.
The "check" terminology is somewhat ambiguous as the non-boolean return
suggests that '0' might mean "success", i.e. suggests that the ioctl uses
the 0/-errno pattern. Provide a wrapper instead of trying to find a new
name for the raw helper; the "check" terminology is derived from the name
of the ioctl, so using e.g. "get" isn't a clear win.

Add TEST_REQUIRE() and __TEST_REQUIRE() to replace the myriad open coded
instances of selftests exiting with KSFT_SKIP after printing an
informational message. In addition to reducing the amount of boilerplate
code in selftests, the UPPERCASE macro names make it easier to visually
identify a test's requirements.
Convert usage that erroneously uses something other than print_skip()
and/or "exits" with '0' or some other non-KSFT_SKIP value.
Intentionally drop a kvm_vm_free() in aarch64/debug-exceptions.c as part
of the conversion. All memory and file descriptors are freed on process
exit, so the explicit free is superfluous.

I guess this one was missed on the initial conversion of kvm_check_cap to
kvm_has_cap, but it doesn't matter.

... got carried into the TEST_REQUIRE, so it sort of matters.

Add a static assert to the KVM/VM/vCPU ioctl() helpers to verify that the
size of the argument provided matches the expected size of the IOCTL.
Because ioctl() ultimately takes a "void *", it's all too easy to pass in
garbage and not detect the error until runtime. E.g. while working on a
CPUID rework, selftests happily compiled when vcpu_set_cpuid()
unintentionally passed the cpuid() function as the parameter to ioctl()
(a local "cpuid" parameter was removed, but its use was not replaced with
"vcpu->cpuid" as intended).
Tweak a variety of benign issues that aren't compatible with the sanity
check, e.g. passing a non-pointer for ioctls().
Note, static_assert() requires a string on older versions of GCC. Feed
it an empty string to make the compiler happy.

While we've gained the static asserts we've also lost the type checking
that the inline functions provided. Is there anyway we can bring them back
with more macro tricks?

The last two changes don't really belong in this commit, but I won't tell
anyway, if you don't.

Gah, I overthought this. It doesn't even require macros, just a dummy helper.
I wasn't trying to use static_assert() to enforce the type check, which is how I
ended up with the sizeof() ugliness (not the one above). But it's far easier to
let the compiler do the checking.
I'll send a small fixup series to address this and your other feedback.

Raghu is going to run on arm64, I'll work with him to iron out any bugs (I should

tests we can't run.

arm64 is quite broken, the only tests that pass are those that don't actually
enter the guest. Common tests, e.g. rseq and memslots tests, fail with the same
signature, so presumably I botched something in lib/aarch64, but I haven't been
able to find anything via inspection.
Raghu is bisecting...

Ha! Looks like it's an issue with running upstream selftest using one of our many
internal framework things. Running a few of the tests manually works. We should
have full results tomorrow.
I did find one bug during my inspection, in case someone gets ambitious and wants
to run tests too :-)

Can you please, pretty please, once and for all, kill that alias you
seem to have for me and email me on an address I actually can read?
I can't remember how many times you emailed me on my ex @arm.com address
over the past 2+years...
The same thing probably applies to Sean, btw.

Ha! I was wondering how my old @intel address snuck in...
On the aarch64 side, with the following tweaks, courtesy of Raghu, all tests
pass. I'll work these into the next version, and hopefully also learn how to
run on aarch64 myself...
Note, the i => 0 "fix" in test_v3_typer_accesses() is a direct revert of patch 3,
"KVM: selftests: Fix typo in vgic_init test". I'll just drop that patch unless
someone figures out why doing the right thing causes the test to fail.

Hmm, looks like something, somewhere for AArch64 needs improving to avoid
strangeness like this. I'll look into it after we get this series merged.

Huh, you're right, that is odd. Ah, duh, aarch64_vcpu_add() allocates a stack
for the vCPU, and that will fail if there's no memslot from which to allocate
guest memory.
So, this is my goof in
KVM: selftests: Rename vm_create() => vm_create_barebones(), drop param
get-reg-list should first be converted to vm_create_without_vcpus(). I'll also
add a comment explaining that vm_create_barebones() can be used with __vm_vcpu_add(),
but not the "full" vm_vcpu_add() or vm_arch_vcpu_add() variants.

Actually, I agree with your assessment. A better solution is to open code the
calls to add and setup the vCPU. It's a small amount of code duplication, but I
actually like the end result because it better documents the test's dependencies.
Assuming it actually works, i.e. the stack setup is truly unnecessary, I'll add a
patch like so before the barebones change.

Figured it out, "val" should be "i * 0x100", not "0". The asserts in this test
are awful and don't print the actual "val". test_assert() shares part of the blame

Hrm, that's odd, it's based directly on kvm/queue, commit 55371f1d0c01 ("KVM: ...).

Duh, Paolo updated kvm/queue. Where's Captain Obvious when you need him...

I pushed a new version that's based on the current kvm/queue, commit 5e9402ac128b.
arm and x86 look good (though I've yet to test on AMD).
Thomas,
If you get a chance, could you rerun the s390 tests? The recent refactorings to
use TAP generated some fun conflicts.
Speaking of TAP, I added a patch to convert __TEST_REQUIRE to use ksft_exit_skip()
instead of KVM's custom print_skip(). The s390 tests are being converted to use
TAP output, I couldn't see any advantage of KVM's arbitrary "skipping test" over
TAP-friendly output, and converting everything is far easier than special casing s390.

Sounds like a good idea to me. I already considered starting to convert some
x86 tests, too
(https://lore.kernel.org/linux-kselftest/20220429071149.488114-1-thuth@redhat.com
), but didn't get much feedback there yet, but anyway, we'll be better
prepared with your change for that now.

I did so, rebased over David's nested dirty_log_perf_test patches and
pushed to kvm/queue.

Hi,
I just checked your series on s390x, and as far as I can see, the tests
still work fine with the patches applied. Thus:

Hi Sean,
I've completed a thorough skim / review and it looks great to me. Besides
the final patch where I'm wondering about the loss of the type checking
on our ioctl wrappers, I don't think there are any patches where I
wouldn't be happy to add an r-b. So, for the series, except the last patch
