[PATCH i-g-t v3 0/7] Xe: Add tests for PXP

[PATCH i-g-t v3 0/7] Xe: Add tests for PXP

[Daniele Ceraolo Spurio]

Given that PXP introduces new interfaces and behaviors, we need to
update existing IGTs and add new ones to cover all the new scenarios.

Minor changes have been done to common functions to propagate the
PXP info and error returns.

v3: part of the v2 series has been split off and merged (see [1]) to
allow the kernel side to be merged without IGT failures. This is rebased
on top of that and addresses the review comments on v2 on the remaining
patches.

[PATCH i-g-t v3 2/7] tests/intel/xe_vm: Update invalid flag subtest with valid PXP flag

[Daniele Ceraolo Spurio]

The invalid flag subtest also checks all the valid flags, so add the new
PXP flag to it.

v2: only test the new flag if the kernel supports it.
v3: rebase on the split of the update on the first invalid flag number
to its own patch.

[PATCH i-g-t v3 4/7] tests/intel/xe_pxp: Add PXP object and queue creation tests

[Daniele Ceraolo Spurio]

PXP support introduces new SET_PROPERTY extensions to both BOs and
exec_queues to mark them as being used for PXP workloads, so we need to
test both correct and incorrect usage of those new interfaces.

Since this is the first usage of extensions for BO creation, the
common BO code has been update to support the extra parameter.

v2: fix memory lead, remove unneeded igt_require (Alan)

[PATCH i-g-t v3 5/7] tests/intel/xe_pxp: Test PXP submissions

[Daniele Ceraolo Spurio]

The render supports PXP usage via rendercopy. We can use this to test
that a user is able to correctly encrypt their data. In particular, we
cover these 2 scenarios:

1) copy from clear to encrypted - we expect the dest buffer to not match
   the src one due to the encryption.

2) copy from encrypted to encrypted = we expect the 2 BOs to match since
   they hold the same data encrypted with the same key.

Note that the clear to clear copy is already covered by the
xe_render_copy test, while encrypted to clear is obviously not a
supported case.

Since the render_copy uses the intel_batchbuffer helpers, those helpers
have been updated to support vm bind of protected objects.

v2: move igt_require calls inside the subtest
v3: Better comments for rsvd1 overload, rename variables for clarity,
updated commit msg.

[PATCH i-g-t v3 6/7] tests/intel/xe_pxp: Termination tests

[Daniele Ceraolo Spurio]

There are several events that can cause the PXP key to be invalidated
and trigger a PXP termination (suspend, PXP termination irq). After a
termination, we expect the key to be different and the raw encrypted
data to change for the same source data.
Additionally, all PXP objects are invalidated during a termination and
can no longer be used in submission or kept mapped to VMs; we therefore
need to test both the execution and bind ioctls to make sure they work
as expected after a termination.

v2: move igt_require calls inside the subtest
v3: block rpm for tests trying a different type of termination, rework
invalid bind test to try a new vm as well (Alan)

I have few nits, one is from our CI fail:

../tests/intel/xe_pxp.c:1065:53: error: ‘O_RDONLY’ undeclared (first use in this function); did you mean ‘STA_RONLY’?
fw_handle = igt_debugfs_open(fd, "forcewake_all", O_RDONLY);
                                                  ^~~~~~~~
						 STA_RONLY
../tests/intel/xe_pxp.c:1065:53: note: each undeclared identifier is reported only once for each function it appears in

Please include a proper lib header in a first patch which uses O_RDONLY.

Rest nits below.

This should be in each subtest which needs this.

This should also be in fixture, consider creating xe_pxp_pm test.

Same here, both close() and ...restore...() should be done in
igt_fixture { ... }

To test if all is ok call your test with --show-testlist
without sudo:

./xe_pxp --show-testlist

This builds fine for me locally, I guess I'm getting O_RDONLY from some 
system include. I'll fix it.

is it ok if I move everything inside igt_subtest, without using 
igt_fixture? it makes things much simpler in code and I'm getting no 
errors from --show-testlist when doing so.

[PATCH i-g-t v3 7/7] tests/intel/xe_pxp: Test encrypted FBs

[Daniele Ceraolo Spurio]

PXP allows a user to send an encrypted BO to the display HW without
having to decode it. The driver needs however to tell the HW that the
BO is encrypted, otherwise it won't be displayed correctly. Furthermore,
if PXP is terminated before the FB is displayed, we expect to see a black
screen instead of what's in the BO.

We can test both these flows by by displaying the expected image from a
non-encrypted FB and and making sure that the CRC match when we display
the encrypted FB.

v2: move igt_require calls inside the subtest
v3: move repeated code to an helper (Alan)
