To: palves, brobecker; +Cc: gdb-patches, Walfred Tedeschi
In the previous patch a new set of target descriptors
(i386|amd64)-avx-mpx were added being same as the (i386|amd64)-mpx.
This patch removes AVX feature from (i386|amd64)-mpx target
descriptor set.
This way the (i386|amd64)avx_mpx(_linux|) set has AVX and MPX features
and (i386|amd64)mpx(_linux|) only MPX.
2016-02-04 Walfred Tedeschi <walfred.tedeschi@intel.com>
* features/i386/amd64-mpx-linux.xml: Remove AVX feature.
* features/i386/amd64-mpx.xml: Remove AVX feature.

Add a redundant target description for the MPX and AVX case using a
combined feature name to reflect that, i.e. avx-mpx.
Usage of both series of target descriptor (avx-mpx and mpx) were also fixed.

From: Walfred Tedeschi @ 2016-03-03 17:26 UTC (permalink / raw)
To: palves, brobecker; +Cc: gdb-patches, Walfred Tedeschi
CPU features can occur in any combination. The current assumption that
feature "A" implies in feature "B" does not necessarily hold.
This patch series construct an additional combination of the Intel(R)
Memory Protection Extensions (MPX) with Intel(R) Advanced Vector
Extensions (AVX).
Starting from the current implementation that has MPX combined with AVX.
A new target description having only MPX will be created using a two
step approach as described below:
First step:
Mirror (i386|amd64)mpx target descriptors onto (i386|amd64)-avx-mpx
ones.
Add a redundant target description for the MPX and AVX case using a
combined feature name to reflect that, i.e. avx-mpx. A new flag 2is
also added to address MPX case without AVX.
Second step:
Refactor (i386|amd64)-mpx target descriptors.
AVX feature is removed from the set of files that described MPX alone
feature. Present on GDB code previous to this patch.
Tests were done with hardware having MPX and AVX as is.
For MPX standing alone tests were done forcing the XCR0 bits.
Difference since V1:
* Added -api support missing as reported by Marcin.
Thanks and regards,
-Fred
Walfred Tedeschi (2):
Add redundant target descriptor for tdesc(amd64|i386)_avx_mpx_*
Re-factor (i386|amd64)mpx target descriptors.

It's better when commit logs are self-contained and don't
depend on info in the cover letter. The cover letter doesn't
make it to git.
E.g.,
~~
Subject: Add target descriptions for AVX + MPX
The current MPX target descriptions assume that MPX is always
combined with AVX, however that's not correct. We can have
machines with MPX and without AVX; or machines with AVX
and without MPX.
This patch adds new target descriptions for machines that
support both MPX and AVX, as duplicates of the existing
MPX descriptions. The following commit will remove AVX from
the MPX-only descriptions.
~~
(Note s/descriptors/descriptions in subject)

The comment sounds odd to me. Does this intend to say:
/* Neither AVX nor MPX are available on x32. */
?
Is it really true that x32 does not support AVX?

Ok, you are right. Intention was to present the full picture. But then
this is lost in the commit itself.

It is that the switch and the flags used to select the right descriptor
was also adapted.

It is odd. I will take a look in fact it's MPX will not be available for
x32.

Pedro and all,
Thanks again for your review!
V3 will come soon, however we have a finding that needs to be addressed!
The reading of registers and the definition for the target descriptions
can trigger an assertion. I will address it on an additional patch.
Here we selected the target description according to the XCR0 bits. But
we might select one target description that has the XCR0 bits for a
feature but registers are not named in there. E.G. XCR0 =
X86_XSTATE_AVX_MPX_MASK returning a tdesc_x32_avx_linux.
switch (xcr0_features_bits)
{
case X86_XSTATE_MPX_AVX512_MASK:
case X86_XSTATE_AVX512_MASK:
if (is_x32)
return tdesc_x32_avx512_linux;
else
return tdesc_amd64_avx512_linux;
case X86_XSTATE_MPX_MASK:
if (is_x32)
return tdesc_x32_avx_linux; /* No MPX on x32 using AVX. */
else
return tdesc_amd64_mpx_linux;
case X86_XSTATE_AVX_MPX_MASK:
if (is_x32)
return tdesc_x32_avx_linux; /* No MPX on x32 using AVX. */
else
return tdesc_amd64_avx_mpx_linux;
case X86_XSTATE_AVX_MASK:
if (is_x32)
return tdesc_x32_avx_linux;
else
return tdesc_amd64_avx_linux;
default:
if (is_x32)
return tdesc_x32_linux;
else
return tdesc_amd64_linux;
}
Here based on XCR0 we look for the register, but it is not in the target
description.
if ((x86_xcr0 & X86_XSTATE_MPX))
{
int ymm0h_regnum = find_regno (regcache->tdesc, "bnd0raw");
Here we assert.
int
find_regno (const struct target_desc *tdesc, const char *name)
{
int i;
for (i = 0; i < tdesc->num_registers; i++)
if (strcmp (name, tdesc->reg_defs[i].name) == 0)
return i;
internal_error (__FILE__, __LINE__, "Unknown register %s requested",
name);
}
My proposal would be to create another variable to keep the actual
feature bits when detecting the target description to be used.
Thoughts?
Thanks and regards,

First of all, I am not against your patches. Just think a little more
after reading them...
This reveals a problem in gdb target description. It doesn't scale very
well if processors have multiple different features, and features can be
combined differently. A processor family has three features A, B, and
C, and each processor implementation may have one, two or three of these
features. In gdb target description, we need to have many *.xml and *.c
files, for these combinations like, A, B, C, AB, AC, BC, and ABC.
The root cause is that target description are static and pre-generated.
If the target description can be generated dynamically according to the
cpuid or AT_HWCAP, that would be simpler. In this way, we only have to
define target descriptions for feature A, B, and C, and GDB/GDBserver
combine them together in the runtime.

I agree. This is not the first time this is suggested. If someone were

Hello all,
Firstly we also agree! :)
We have to agree upon a strategy and a design for that.
I would propose that we go in the way it is by now for the patches that
are under review for me and Michael. Those patches impact technology
that is already public.
Together with that we discuss the design on how to stich the target
descriptions together.
Would you agree with that?
In terms of the design:
During this time we also proved that it would be possible to have a
single target description and selecting the features to be added
according to the feature bits during run time.
The elegant option is of course the composition of the target
description under run time. But there is also the consideration of how
complex it would be.
Have you already had some thoughts about that? Can you point us to some
discussion about the topic?
Thanks a lot for the reviews and thoughts and best regards,
-Fred

Please share your thoughts as well...

I'm recalling this being brought up at some Cauldron, and maybe
(ISTR) Luis bringing that up on the gdb list somewhere. ISTR recall
this coming up for MIPS as well. But I don't have pointers handy.
I don't have a quick answer. Below's a couple minutes worth of
thought, all I could spare right now.
Always going through a xml built at run time might be the simplest.
However, even that poses challenges.
The xml-building part itself wouldn't be anything complicated. Just
something along the lines of:
x86_linux_read_description ()
{
strcat (output, target_xml_header);
if (feature_foo_supported)
strcat (output, "<xi:include href="feature-foo.xml"/>");
if (feature_bar_supported)
strcat (output, "<xi:include href="feature-bar.xml"/>");
strcat (output, target_xml_footer);
return output;
}
However, gdb needs its own set of built-in target descriptions as
well, for core file debugging, etc., and always going through
the xml indirection would mean that libexpat becomes a hard requirement
for native and core debugging as well, and, it'd require installing
the xml files in the data-directory, along side gdb. It's convenient NOT to
have to install the xml files today, but maybe that's not a deal breaker.
Also, then there's the gdbserver side. gdbserver also makes use of the target
descriptions for more than feeding a xml version back to gdb, and of course
gdbserver doesn't parse the xml files at all. They're instead converted at
build time to whatever gdbserver needs. So whatever design we come up with
needs to address this as well. Going the always-xml direction means that now
gdbserver needs to link with expat and parse the xml files.
Or maybe we could come up with a design that avoids having gdbserver parse
xml, by still converting the feature xml files to C at build time (like, generate
a set of struct target_desc_feature objects (which don't exist today), which would
correspond to each feature that could be xinclude'd), and then at run time compose
a struct target_desc from those struct target_desc_feature object, as well as a xml
file to send back to gdb.

Pedro and All,
I was looking for Luis comments and I saw that he also would like to
extend the xml files so the hard coded values in gdb could be also
reduced. That is an improvement on the target description scheme that
makes a lot of sense. I would enjoy to see the number of tables we have
reduced.
In refactoring the target description reading should/could we also
consider that?
Regarding the gdbserver side: I was wondering that for the user it might
be more complex to deliver the XML file set + gdbserver to target
device, or?
Aside of that, the idea to make gdbserver parsing the xml looks good
simplifying the handling.
Thanks and regards,
-Fred
