[Qemu-devel] [PATCH v7 00/12] More fully implement ARM PMUv3

[Qemu-devel] [PATCH v7 00/12] More fully implement ARM PMUv3

[Aaron Lindsay]

The ARM PMU implementation currently contains a basic cycle counter, but
it is often useful to gather counts of other events, filter them based
on execution mode, and/or be notified on counter overflow. These patches
flesh out the implementations of various PMU registers including
PM[X]EVCNTR and PM[X]EVTYPER, add a struct definition to represent
arbitrary counter types, implement mode filtering, send interrupts on
counter overflow, and add instruction, cycle, and software increment
events.

Since v6 [1] I have made the following changes:
* Use cpu_get_host_ticks() for the cycle counter value for user mode
* Re-staged "PMU: Set PMCR.N to 4" so that the value of the pmcrn local
  variable matches the architectural value of PMCR.N
* Re-ordered "Reorganize PMCCNTR accesses" to come first to eliminate
  the churn of *_op_start/finish function names and definitions
* Use extract64 and ARRAY_SIZE macros where applicable
* Add a return value to the post_save migration function

[Qemu-devel] [PATCH v7 01/12] migration: Add post_save function to VMStateDescription

[Aaron Lindsay]

In some cases it may be helpful to modify state before saving it for
migration, and then modify the state back after it has been saved. The
existing pre_save function provides half of this functionality. This
patch adds a post_save function to provide the second half.

[Qemu-devel] [PATCH v7 02/12] target/arm: Reorganize PMCCNTR accesses

[Aaron Lindsay]

pmccntr_read and pmccntr_write contained duplicate code that was already
being handled by pmccntr_sync. Consolidate the duplicated code into two
functions: pmccntr_op_start and pmccntr_op_finish. Add a companion to
c15_ccnt in CPUARMState so that we can simultaneously save both the
architectural register value and the last underlying cycle count - this
ensures time isn't lost and will also allow us to access the 'old'
architectural register value in order to detect overflows in later
patches.

The comment says that pmu_op_start returns a value and pmu_op_finish
has a second argument, but the prototypes disagree...

Otherwise

so if this turns out to be the only problem I can fix it up when
I apply it to my tree, if you provide suitable new comment text.

Doh, I updated the comment for pmccntr_op_* but missed pmu_op_*. The

I've also updated the comment text in my tree, so if/when there is a v8

[Qemu-devel] [PATCH v7 03/12] target/arm: Swap PMU values before/after migrations

[Aaron Lindsay]

Because of the PMU's design, many register accesses have side effects
which are inter-related, meaning that the normal method of saving CP
registers can result in inconsistent state. These side-effects are
largely handled in pmu_op_start/finish functions which can be called
before and after the state is saved/restored. By doing this and adding
raw read/write functions for the affected registers, we avoid
migration-related inconsistencies.

This will end up calling pmu_op_start() and pmu_op_finish()
even if the guest is running KVM and we're not using the
TCG code. Is that what you intended?

The counters are still stored in their 'difference' format for KVM, so I
think this still makes sense. Or is there something I'm missing about
how this will interact with KVM? I'm much more familiar with TCG.

For KVM the counter values are stored in the kernel, until the
write_kvmstate_to_list() function (which is performed after your
pmu_op_start() call in cpu_pre_save()) writes them from the
kernel into the cpreg_vmstate array. Similarly on load they
go straight from the vmstate array into the kernel registers.
It's not clear to me what the pmu_op_start()/finish() calls
are intended to do in the KVM case, and they look at fields
in the env->cp15 struct which will not have valid values at
this point.

Oh, I had a fundamental misunderstanding and expected the registers
would be in env->cp15 when this was called, even for KVM.

After looking into this more, it seems like my pmu_op_* calls here
should be contained in `if (!kvm_enabled())` blocks. It doesn't seem
like anything bad would happen otherwise, but it also isn't necessary or
helpful to make those calls.

I'll make this change for v8 if you don't have further feedback.

Rename arm_ccnt_enabled to pmu_counter_enabled, and add logic to only
return 'true' if the specified counter is enabled and neither prohibited

[Qemu-devel] [PATCH v7 07/12] target/arm: Add array for supported PMU events, generate PMCEID[01]

[Aaron Lindsay]

This commit doesn't add any supported events, but provides the framework
for adding them. We store the pm_event structs in a simple array, and
provide the mapping from the event numbers to array indexes in the
supported_event_map array. Because the value of PMCEID[01] depends upon
which events are supported at runtime, generate it dynamically.

This now sets one of the ID registers for "we have no
PMU" in the first "if (!cpu->has_pmu)" statement (id_aa64dfr0),
and some of them (pmceid0, pcmeid1) in this else clause at the
end. We should put them all in the same place.

This doesn't look like the right API, because in AArch64
PMCEID0_EL0 and PMCEID1_EL0 are both 64-bit registers,
so you can't fit them both into a single uint64_t.

I agree that would be cleaner - I'll move the id_aa64dfr0 update to
later else clause.

Heh, I think I started working on this long enough ago that I was using
a copy of the ARMv8.0 ARM - before the statistical profiling extensions
were announced. I believe those are the only currently-defined common
events >= 0x4000, so they're the only bits defined in the upper 32 bits
of PMCEID[01].

Now that I look at it, pmceid[01] are currently only defined as
uint32_t, and we don't have PMCEID[23] for the high bits for AArch32.
Perhaps that should be a separate patch.

At any rate, I'll plan to update this the following signature for the
next version, where `which` is [01] for which PMCEID is being requested.
For now I'll probably just put a comment about not supporting the 0x40xx
events, since I don't know that coming up with a sparse array is worth
it, but the signature will be appropriate if we add support later:

uint64_t get_pmceid(CPUARMState *env, unsigned which);

[Qemu-devel] [PATCH v7 08/12] target/arm: Finish implementation of PM[X]EVCNTR and PM[X]EVTYPER

[Aaron Lindsay]

Add arrays to hold the registers, the definitions themselves, access
functions, and logic to reset counters when PMCR.P is set. Update
filtering code to support counters other than PMCCNTR. Support migration
with raw read/write functions.

[Qemu-devel] [PATCH v7 09/12] target/arm: PMU: Add instruction and cycle events

[Aaron Lindsay]

The instruction event is only enabled when icount is used, cycles are
always supported. Always defining get_cycle_count (but altering its
behavior depending on CONFIG_USER_ONLY) allows us to remove some
CONFIG_USER_ONLY #defines throughout the rest of the code.

With PMCR.N > 0, this means that MDCR_EL2.HPMN behaviour and
more generally support for the EL2 performance monitor trapping
options in MDCR_EL2 become relevant. But I think we're probably
best off leaving that for a future patchset.

[Qemu-devel] [PATCH v7 12/12] target/arm: Send interrupts on PMU counter overflow

[Aaron Lindsay]

Setup a QEMUTimer to get a callback when we expect counters to next
overflow and trigger an interrupt at that time.

Peter,

It looks like there's probably going to be at least a v8 in this series
since you've made a few comments which require changes. But I don't
think this final patch has ever received any review comments from
anyone, and I suspect it's not because it's perfect...

Would you mind taking a look at this one during your review if you can
find time?

Thanks!
