The current test for functional interrupts is broken in multiple ways:
1. The needed flag TPM_CHIP_FLAG_IRQ is never set, so the test is never
executed.
2. The test includes the check for two variables and the check is done for
each transmission which is unnecessarily complicated.
3. Part
initialized its AMX state.
Collect the test cases of validating those operations together, as they
share some common setup for the AMX state.
These test cases do not depend on AMX compiler support, as they employ
userspace-XSAVE directly to access AMX state.

On this kernel version, those modules set to Y will not use the sha512
algorithm.
And our SEC module selects it "select CRYPTO_SHA512", so it is compiled into
ko: "sha512_generic.ko".
Because we did not load the "sha512_generic.ko" when we loaded the ko of SEC,
the sha512 algorithm test failed, Therefore, before using SEC,
we need to load this ko first, so this patch is not required, please ignore it.
Thanks
Longfang.
This adds a test for the positive case of the wait killable notifier,
in testing that when the feature is activated the process acts as
expected -- in not terminating on a non-fatal signal, and instead
queueing it up. There is already a test case for normal handlers
and preemption.

This builds on the previous changes to tests/shell/buildid.sh, adding
tests for a PE file. It adds it to the build-id cache manually and, if
Wine is available, runs it under "perf record" and verifies that it was
added automatically.
If wine is not installed, only warnings are printed
