This patch series implements access to additional powerpc registers on
linux targets.
The new register are:
* The Program Priority Register.
* The Data Stream Control Register, used for cache control.
* The Target Address Register.
* The Hardware Transactional Memory registers, which include both a
set of three special-purpose registers that control the HTM facility
and the set of checkpointed registers, a copy of most of the other
registers used as a snapshot to restore processor state in the event
of a transaction failure.
* The Event-Based Branch (EBB) facility and Performance Monitoring
Unit (PMU) registers.
The first four patches refactor some parts of the code affected by the
patches.
Each group of registers is then enabled with one patch for support in
the native and core file targets and one for gdbserver support. Some
also have patches for related record/replay support and tests.
PPR and DSCR did not appear in the architecture at the same
time, but for simplicity they are added in a common tdesc. They will
be separated when I change the powerpc linux targets to use flexible
tdescs in the future.
Adding the HTM checkpointed registers has nearly doubled the number of
registers which causes regressions because some internal buffer sizes
related to tracepoints are longer be sufficient. These are being
addressed in separate patches:
https://sourceware.org/ml/gdb-patches/2018-06/msg00501.html
That is V1 of the series that only addresses one of the regressions, I
will send a V2 that also addresses another related regression when
saving a trace file wiht -ctf.
This series also depends on binutils patch recently submitted that
enables writing and reading the core file note sections for these
register sets:
https://sourceware.org/ml/binutils/2018-07/msg00191.html
Much of the original work to implement access to these registers was
done by Edjunior when he was at IBM, so I have kept him as the author
in the patches he had worked on. I have made modifications to these
patches, so I have also added myself to the changelog entries for
these patches, in addition to Edjunior. Errors in these patches might
be my own.

This patch changes rs6000_register_reggroup_p to use
default_register_reggroup_p when possible.
Group membership for SPE, VSX and EFP pseudoregisters can be detected
through their types in default_register_reggroup_p. DFP pseudoregs
still need special handling when checking membership to the float
group, because default_register_reggroup_p doesn't consider registers
with type code TYPE_CODE_DECFLOAT to be part of the float group.
gdb/ChangeLog:
YYYY-MM-DD Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* rs6000-tdep.c (rs6000_pseudo_register_reggroup_p): Call
default_register_reggroup_p.

From: Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com>
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for other registers with other info (e.g., nip is filled with
the contents of TFHAR). GDB doesn't handle these other registers. This
means that core files generated by GDB will show values of zero for
these registers, while core files generated by the kernel will have
other values. Core files generated by the kernel have a note section
for checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second
half. GDB generates a smaller note section for 32-bit threads, but can
read both sizes.
Access to the checkpointed CR (condition register) can be
confusing. The architecture only specifies that CR fields 1 to 7 (the
24 least significant bits) are checkpointed, but the kernel provides
all 8 fields (32 bits). The value of field 0 is not masked by ptrace,
so it will sometimes show the result of some kernel operation,
probably treclaim., which sets this field.
The checkpointed registers are marked not to be saved and
restored. Inferior function calls during an active transaction don't
work well, and it's unclear what should be done in this case. TEXASR
and TFIAR can be altered asynchronously, during transaction failure
recording, so they are also not saved and restored. For consistency
neither is TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised. When gdb tries to store to
all registers in one go (when store_registers called with -1), the
state of these registers is checked. If they are all unavailable, no
write is attempted, so that writes to all the other registers are
unaffected. If all are available, the write is attempted. Otherwise an
internal_error is raised.
Like for the previous patches, configure.srv is updated here to avoid
breaking the build at this patch.

To: gdb-patches; +Cc: uweigand, edjunior
From: Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com>
This patch adds support for the Target Address Register for powerpc
linux native and core file targets.
Like for the PPR and DSCR patch, the .dat files and configure.srv
changes are included here to avoid breaking the build at this point.

From: Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com>
This patch adds gdb support for the Program Priorty Register and the
Data Stream Control Register, for the powerpc linux native and core
file targets.
The gdbserver implementation comes in the next patch. However, because
powerpc target description declarations are common to gdb and
gdbserver, the .dat files and gdbserver/configure.srv are altered
here, in order to avoid breaking the build at the commit corresponding
to this patch.

This patch extends suport for the HTM registers to the powerpc linux
gdbserver stub.
The "fill" functions for checkpointed register sets are not
implemented, because ptrace can return ENODATA for these regsets
whenever the inferior is not in a transaction.
Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when it is
not in a transaction, so there is currently no straightforward way to
handle this case. This means the checkpointed registers in the
client-side regcache can become dirty when the user tries to write to
them, until the inferior is resumed and stopped again.
Another limitation for the checkpointed registers is that traceframes
don't record if registers are available or not, so if these registers
are collected when a tracepoint is hit and the inferior is not in a
transaction, the user will see zero values for all of them, instead of
the usual <unavailable>.

From: Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com>
This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets.
All three EBB registers are accessible. Only a subset of the PMU
registers can be accessed through ptrace. Because of this, the PMU
registers are enumerated indivitually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag. This is intended to make it easier to
add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct.
It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously. They are also not tracked in record-replay mode.
Currently, the kernel can return ENODATA when ptrace is used to get
the EBB registers, unless a linux performance event that uses EBB is
open in the inferior. However, EBB registers are always saved and
restored by the kernel, but not the PMU registers, so the ENODATA
might have been meant for the PMU registers. For this reason GDB
handles ENODATA for both regsets.
Like for the previous patches, configure.srv is updated here to avoid
breaking the build at this patch.

This patch adds a test for acces to checkpointed HTM registers in
GDB.
The tests records the values of the regular registers before stepping
the inferior through a "tbegin." instruction to start a transaction,
then the checkpointed registers are checked against the recorded
pre-transactional values. New values are written to the checkpointed
registers and recorded, the inferior continues until the transaction
aborts (which is usually immediately when it is resumed), and the
regular registers are checked against the recorded values, because the
abort should have reverted the registers to these values.

* gdb.arch/powerpc-htm-regs.c: New file.

This is OK with me, but it might actually be even better to change
default_register_reggroup_p to consider TYPE_CODE_DECFLOAT registers

I guess it would make sense to combine those (together with the tests
and the record/replay support) into a single commit then.

This should be done *only* for OR, not for any of the others that

Well, this is weird. Either the kernel should be fixed to use the
smaller size as well, or else GDB should also generate the large
section (and zero out the second half).

Huh. We shold report this to the kernel people.

I'm not sure I like this approach. The problem is only about
generating core files, right? Why don't we instead simply
change linux-tdep.c:linux_collect_regset_section_cb from
buf = (char *) xmalloc (size);
regset->collect_regset (regset, data->regcache, -1, buf, size);
to use xcalloc instead? This seems prudent anyway. (The same applies
to the similar code in fbsd-tdep.c.)
Then we can probably even get rid of ppc_linux_collect_vrregset as well.

Hmm. The DFP and EFP pseudo registers are simply GDB views onto the
normal FP / VR register set. For completeness, shouldn't we also offer
similar views onto the checkpointed register set?

It looks a bit odd that we need to use variable numbers for
the vr0 / fp0 / vsr0 registers, but can hard-code the numbers
for the checkpointed register set. Why is this the case?

Hmm. It's a bit unfortunate to have these differences between native
and gdbserver debugging. But I guess this is unavoidable for now.

Adding these in the middle causes a bit of churn in the generated files.
(It re-shuffles the gdbserver protocol register buffer instead of just
adding to the end.) Now this *should* still all be compatible, but I
guess it would be better to avoid the churn; either add this patch
before the HTM patch, or else change the sequence in the XML file.

Similar comment to above, can we not avoid this renumbering churn?
Also, I see you haven't got any test cases for this? Would these
be difficult to add?

Why do this? Can't we recorder the XML file to make the order

OK.
One more thing about the checkpointed registers: Linux doesn't currently
support AMR, but it is specified by the architecture to be checkpointed
as well. If it is added in the future, its checkpointed version will
either need to be a separate tdesc feature or rs6000_gdbarch_init will
have to accept a org.gnu.gdb.power.htm feature with and without it.
The tdep object might also need a separate field, since it won't be
possible to rely on tdep->have_htm to know if a checkpointed amr is
available in the gdbarch. This is different from the approach I took for
the incomplete pmu registers, where I enumerated all the ones that are
there in the tdep object. Doing this for all the htm registers would add
a lot more fields.

Yes, this seems like a much simpler approach.

OK. I had removed them thinking they weren't going to be used a lot, but
I'll put them back in for completeness.

There isn't a good reason, I probably just didn't change the way it was
done for the regular registers. I will change them to use the hard-coded
numbers for consistency (there is no tdep field for cvsr0_upper, cfp0
and cvr0).
Thank you for the reviews!

Yes, I will change this.

It's a bit harder, because it's not so straightforward to open the
performance events to put the inferior in a state where the ebb/pmu
registers are meaningful. I have a kludgy test I used, I'll try to make
it better for submission.
Thanks!

I wanted to keep the registers in the tdescs in the order they were
defined in the isa, since the tdescs are used in common powerpc code (in
rs6000_gdbarch_init), and so are the fixed register numbers (in
ppc-tdep.h), and the order they appear in the ptrace buffer is specific
to Linux. But if this isn't a big deal I can change that to simplify
this code.
Thanks!
