[PATCH v2 0/9] memory: assert and define MemoryRegionOps callbacks

[PATCH v2 0/9] memory: assert and define MemoryRegionOps callbacks

[P J P]

From: Prasad J Pandit <pjp@fedoraproject.org>

Hello,

* This series asserts that MemoryRegionOps objects define read/write
  callback methods. Thus avoids potential NULL pointer dereference.
  ex. -> https://git.qemu.org/?p=qemu.git;a=commit;h=bb15013ef34617eb1344f5276292cadd326c21b2

* Also adds various undefined MemoryRegionOps read/write functions
  to avoid potential assert failure.

Thank you.

What I meant was an error message about illegal/invalid write access.

This will likely be called in tz_ppc_dummy_accepts() above. Do we still want 
to revise this patch? considering read/write callbacks are unreachable.

Thank you.

So a simple comment in each read/write might be sufficient (removing the
qemu_log_mask calls).

  Okay. Will wait for other reviews, before sending a revised series v3. Hope 
that's okay.

Thank you.

The point of g_assert_not_reached() is that it documents and
asserts that the code is not reachable. If the read and write
callbacks are unreachable (which they are) then having their
bodies just be a call to g_assert_not_reached() is the best
way to document that.

The 'flash_ops' is for ROM, though I don't see where it calls
'memory_region_rom_device_set_romd'
to ROMD, so this MR is in MMIO mode and it needs a read callback.

However as the origin code doesn't provide a read callback. So why
here we return something?

I prefer here just 'qemu_log_mask(LOG_UNIMP, "%s not implemented\n",
__func__);' as other
patches does.

I'm not familiar with this platform-related stuff. I think a
'qemu_log_mask(LOG_UNIMP, xxx)' is ok.

Though here is not 100% right as the ROM device can has no read callback.
However the device can change between ROMD mode or MMIO mode.
So I think it's ok the developer can provide a null read callback even if they
don't need it.

Earlier patch v1 did that. It was suggested to return ldl_le_p(), as that's a

Even abort() would do (with a comment).

I think abort() is preferable (while LOG_UNIMP is wrong as it implies
there is something to do that QEMU is not doing).

What would be called in tz_ppc_dummy_accepts()?

Generally g_assert_not_reached is better (even better than abort :)).

Oh, here the UNIMP I understand as it will not be implemented, not the
thing 'should do but not do now'.

If. we use. abort(), the guest also. can trigger this abort(crash).
Though there is also other places we use this I think it is not very good.

In fact I would like to silent ignore(callback do nothing) if the
developer doesn't provide callback at the beginning.
But there are some cases we use LOG_UNIMP:

I think that 'romd mode' (ie reads-go-directly-to-RAM) is
the default: memory_region_initfn() sets romd_mode to true.
So unless the device actively calls memory_region_rom_device_set_romd(mr, false)
then the read callback can't be reached.

No. The message is indeed confusing, as Prasad mixed GuestError
VS UnimplementedFeature.

Guest should not write the the error parity registers (I suppose
they are read-only). If it does, the hardware won't behave
incorrectly, it will just ignore the invalid accesses. We want
to report an incorrect guest behavior (why is the guest code
trying to do that?). Also, we will never implement this.
We usually use something like:

  qemu_log_mask(LOG_GUEST_ERROR,
                "%s: Illegal write to read-only register "
                "(size %u, offset 0x%"HWADDR_PRIx","
                " value 0x04%"PRIx64")\n",
                __func__, size, addr, data);

- Callback missing because we neglected to implement the
  hardware behavior:

  => qemu_log_mask(LOG_UNIMP, ...)

- Callback missing because the access is illegal on hardware
  (write on read-only register, read on write-only register):

  => qemu_log_mask(LOG_GUEST_ERROR, ...)

- Impossible situation unrelated to the hardware/guest behavior
  (problem in QEMU design)

  => g_assert_not_reached()


Note, when we runs QEMU with LOG_UNIMP/LOG_GUEST_ERROR enabled,
we are usually interested in what address the guest is accessing,
and in the write case, what value is written.

|   => qemu_log_mask(LOG_UNIMP, ...)
| 
| - Callback missing because the access is illegal on hardware
|   (write on read-only register, read on write-only register):
| 
|   => qemu_log_mask(LOG_GUEST_ERROR, ...)
| 
| - Impossible situation unrelated to the hardware/guest behavior
|   (problem in QEMU design)
| 
|   => g_assert_not_reached()
| 
| Note, when we runs QEMU with LOG_UNIMP/LOG_GUEST_ERROR enabled,
| we are usually interested in what address the guest is accessing,
| and in the write case, what value is written.

Okay, preparing a revised patch series.

Thank you.
