[PATCH] x86-64: fix ZMM register state tracking

[PATCH] x86-64: fix ZMM register state tracking

[Jan Beulich]

The three AVX512 state components are entirely independent - one being
in its "init state" has no implication whatsoever on either of the other
two. Fully separate X86_XSTATE_ZMM_H and X86_XSTATE_ZMM handling, to
prevent upper halves of the upper 16 ZMM registers to display as if they
were zero (when they aren't) after e.g. VZEROALL/VZEROUPPER.

[Simon Marchi]

Hi Jan,

Would it be possible to update or create a test to exercise that?
arch-specific tests are in testsuite/gdb.arch.

I have some comments about the form.  Tim, could you or somebody
else from Intel take a look at the functional side of the changes?

The GNU standard requires to parenthesis when breaking lines:

  int i, zmm_endlo_regnum = (I387_ZMM0H_REGNUM (tdep)
			     + std::min (tdep->num_zmm_regs, 16));

I'm sure it would be possible, but while I was happy to invest the time to
fix the actual bug (because it affects work I'm doing), I'm afraid I don't have
the time to learn how gdb test cases are to be constructed (I'm familiar
only with the binutils / gas side of things).

This is easy enough to fix (perhaps even without the need to send a v2,
but just before/while committing?); I don't think this is a rule being
enforced on the binutils side, so I simply wasn't aware.

I understand.  If you can provide:

  - a minimal source file (C + assembly in this case, I suppose)
  - GDB commands to reproduce the bug
  - actual and expected output

I can take care of turning it in a GDB test case.

Yeah, no problem, I can do it.  It's suggested in the GNU coding 
standards, so I think it would apply to binutils too:

   https://www.gnu.org/prep/standards/html_node/Formatting.html

Search for "Adding a set of parentheses".

Does gdb/gdbserver/i387-fp.c need similar treatment?

Not afaics - there's no place where both flags would be tested at
the same time (other than was the case here before this patch).

Attached. vzero.s is the source file used (no C file needed). gdb.log
is a transcript of a session with a broken gdb (the one installed on
the system), while gdb.txt is a transcript for the fixed one that I've
built myself.

It would be nice to comment on this magic 16 and the min operation.
It's how XSAVE organizes things but it isn't entirely intuitive.

A comment that XSAVE stores the lower 16 registers in a different place
than the higher 16 registers and also guards them by different XCR0 bits
would be nice.

We hid the different places behind those XSAVE_AVX512_ZMM_H_ADDR
macros but there's nothing similar for the guard bits.  Maybe add macros
for the guard check, as well?

This covers the upper halves of zmm16 to zmm31.  Looking at the function it looks
like the lower halves are covered in separate cases avx512_ymmh_avx512 and
avx512_xmmh_avx512.  Maybe reflect this in the comment?  It currently suggests
that it handles the entire upper 16 registers.

Looks OK to me.

Hi Jan,

Thanks for the instructions.  There is already a test covering AVX512
instructions, so I figured I would add it there.  However, I don't
have a processor that supports AVX512, so I'm unable to run the test.

Here's a patch, can you try to confirm that the test fails without the
fix and passes with the fix?  I probably screwed up somewhere, but it
should be pretty close.

You can run the test with

  $ make check TESTS="gdb.arch/i386-avx512.exp"

in the gdb/ build directory.  The gdb/testsuite/gdb.log file is useful
to look at in case something fails.

Feel free to integrate this in your eventual v2 if there is one, and
feel free to add a comment in the test to say what we are testing here,
as I am not too sure how to describe it.

Thanks!

Simon

Okay, I can accept the desire for a (new) comment here, albeit it pretty
much goes along the lines of what I say further down.

Such a comment would have been appropriate already prior to my patch.
I have to admit that I'm not inclined to invest time in improving
pre-existing (lack of) commentary, the more that how to exactly word
this might be controversial. If that's really a requirement, then I'd
abandon the patch (perhaps for someone else to pick up), maintaining it
locally until the bug has been fixed upstream by whatever means. This
is even more so that the extra time I'll have to put into playing with
Simon's test case is also nothing I really have time for (but I'll try to
find the time nevertheless).

Same here - the split among code regions has been there before (also
for e.g. the YMM register lower and upper halves).

Irrespective of my mostly negative responses thanks for your

There are two issues here: First of all, unrelated to this patch, the
construct around line 95 in i386-avx512.exp should look like

if [is_amd64_regs_target] {
    set nr_regs 32
} else {
    set nr_regs 8
}

Of course this also affects other tests in here, but without this correction
the loop you add does nothing at all.

And then that very loop and the i386-avx512.c addition are not in sync,
and I'm not sure which way you meant it to be: Either in the C file all 16
upper ZMM registers need to be set identically (not just ZMM16), or
there should be no loop.

Furthermore I think the C code addition and hence the test will need to
be x86-64-specific, as registers ZMM8 and higher are inaccessible in
32-bit mode.

So what I can confirm at this point is that with the fix in place there's
one less new failure from the test than with the fix no in place.

Thanks, this has now been fixed in master.

Woops.  Testing only zmm0 and zmm16 will be enough I think.

Good point.

Here's the revised version with this fixed.  I am not sure about the output
for zmm0 though.

[PATCH v2] x86-64: fix ZMM register state tracking

[Jan Beulich]

The three AVX512 state components are entirely independent - one being
in its "init state" has no implication whatsoever on either of the other
two. Fully separate X86_XSTATE_ZMM_H and X86_XSTATE_ZMM handling, to
prevent upper halves of the upper 16 ZMM registers to display as if they
were zero (when they aren't) after e.g. VZEROALL/VZEROUPPER.

So can I translate this into an ack for me to commit the change?
Or else, who would be the one to give the go-ahead?

Simon can approve your patch.

IIRC Pedro had a question regarding gdbserver.  From a first look, it seems to get the
feature bits right but does not distinguish 32-bit and 64-bit mode regarding the number
of available registers.

Did you run the new test you added also in remote configuration?

If there was a problem there, it was my understanding that this can
(and should) be fixed in a separate patch, by someone able to test
this.

No, and I also have no idea how I would go about doing so.

If Markus is happy with the comments, it's all fine with me, please push (I see
you are listed in MAINTAINERS, so I assume you have push access).

Well, you are able to test it (see commands below) :).  But indeed, I think we
should push this patch, which already improves GDB.  It would be nice to at least
get an idea of the status of the test when ran with gdbserver.  Since access to
this hardware is quite limited, it would be appreciated if you could give it a
quick shot and report the results.

Run:

$ make check TESTS="gdb.arch/i386-avx512.exp" RUNTESTFLAGS="--target_board=native-gdbserver"
$ make check TESTS="gdb.arch/i386-avx512.exp" RUNTESTFLAGS="--target_board=native-extended-gdbserver"

in the gdb/ build directory.

Thanks,

Simon

Done.

I'm afraid there's more broken here than just this one test.
Log file attached. I hope you can make sense of it.

> $ make check TESTS="gdb.arch/i386-avx512.exp" RUNTESTFLAGS="--target_board=native-extended-gdbserver"

This produces effectively the same (bad) results.
