This gives us a slightly odd class hierarchy where we have
two "common between bcmxxxx SoCs" types:
TYPE_BCM283X_BASE --> TYPE_BCM283X --> TYPE_BCM2835
| |-> TYPE_BCM2836
| \-> TYPE_BCM2837
\-> TYPE_BCM2838
The only thing TYPE_BCM283X seems to be doing here that
TYPE_BCM283X_BASE is not is handling the BCM2835PeripheralState
object. Would it be clearer to keep the existing
class hierarchy where everything inherits from
TYPE_BCM283X, and accept a little code duplication for
the 3 subclasses that use the same BCM2835PeripheralState?
I'm not sure...
thanks

Ah, looking at the later parts of the patchset I think I
see the issue -- because the board code wants to
embed the SoC object in the machine struct, not having
a common type for the BCM283[567] which is the same size
for all of them would mean that the board code would
also have to split rather than being common for those
SoC types. This is the downside of our "embed the structs"
style of board and SoC code, I guess.
So it's a bit swings-and-roundabouts, and since you've
written the code this way, let's go with doing it this
way. I can always come back and try a refactoring
later if it bothers me too much :-)

Something has gone wrong with the naming here. This is
the SoC implementation, and its peripherals should be
the same whether the BCM2838 is being used on the raspi,
or on any other board. The type names and so on should
be SoC-specific, not board-specific.
thanks

Are these actually variable across different BCM2838 versions?
If not, don't bother making them configurable like this, just
have a #define of the address values and use it directly.
The BCM283[567] code only does this for peri_base and
ctrl_base so it can have one class that handles all three SoCs.

I'm guessing this #define ought to be in a later patch.

Indentation is a bit off here -- usual QEMU standard is that on
subsequent lines, the first character of the argument lines
up with the first character of the argument on line 1, like this:
qemu_log_mask(LOG_UNIMP, "%s: %s: not implemented for %"HWADDR_PRIx"\n",
TYPE_BCM2838_GPIO, __func__, offset);

You also need a vmstate struct, for migration and vmsave/load.

memset(s->fsel, 0, sizeof(s->fsel));
Otherwise

Looking at the last three patches, the code for this
device seems very very similar to the existing
bcm2835_gpio device. What exactly are the differences?
It looks like maybe just the number of powerup/down
registers -- could we share the same device model and
give it a new property for "number of PUP_PDN regs" to
avoid duplicating 300+ lines of code ? Or are there
other differences I've missed?
thanks

Oh, this is where the vmstate struct ended up. I think
I would suggest putting this in patch 6, since that's
where you add the struct fields. (Define the sd_fsel
field there too.)

What are these properties for? I assume you can't change them
on a real raspi 4b board, so why do we need to expose them
to users?

The only differences between these machine types are the
amount of RAM, right? We shouldn't expose that to users
via different board names. Provide a single board
"raspi4b", give it whichever default amount of memory
seems reasonable (I would suggest 1GB or 2GB, it avoids
annoying problems with "make check" on 32-bit hosts), and
let the user pick a different amount of RAM with the -m option
as they usually would. (You can sanitize that to check they
only picked a valid amount of RAM.)
This seems also like a good point to ask for an extra patch
which updates docs/system/arm/raspi.rst to document the
new board type.
thanks

It would be good to note in the commit message that the
"remove devices from dt" code will all go away in following
commits but that it allows a kernel to boot at this point
(assuming that is what it does). That documents the motivation
for what is otherwise a slightly ugly looking hack.

Why do we need to add a memory node ? The commit message
doesn't say anything about doing this.

If you need to get at board-specific info in this hook,
the standard way to do it is to get the MachineState pointer
from the arm_boot_info pointer, like this:
RaspiBaseMachineState *s_base = container_of(binfo,
RaspiBaseMachineState, binfo);
(which works because the arm_boot_info struct is embedded inside the
RaspiBaseMachineState struct).
But in this specific case I think you can probably work with
info->ram_size (it's the ram size adjusted by the vcram_size, I
think, but that's probably OK.)

Then you can avoid this hack.

Rebase/patch split artefact ? This got added in an earlier
patch, so rather than adding and then removing it, better
to not add the line at all.

PCI controllers live in hw/pci-host/ .
I'm not too familiar with the PCI subsystem, so I've cc'd
Marcel and Michael as the PCI maintainers.
The PCI-relevant patches in this series are 14 and 15:

and maybe 16:

Generally registers should be set in some reset method,
not in an instance_init method. (Your base class here
uses 3-phase-reset, so you will need to do so too.)

This comment has been copied from gpex.c, which is an implementation
of a "generic" PCIE controller. Since it's generic, QEMU gets to
decide its behaviour, and since we started with one behaviour and
then changed to a different one we need to provide the property
so that old versioned machine types get the old behaviour.
For the raspi4 PCIe controller, we don't get to decide -- the hardware
will behave in a particular way for accesses to addresses where no PCI
device has been mapped, and we need to follow that.
You should find out whether accesses to unmapped addresses should
cause PCI transaction failures, or read-as-minus-one, and implement
only that behaviour. You don't need to provide a property selecting
between the two.
thanks

Why trace the device instance pointer in these two tracepoints
and not in the others? (Generally we don't, unless there are
multiple devices of the same type in the system and it's important
to be able to distinguish them; and in that case there are
more useful ways to do it than the raw device pointer.)

Do we really need all these properties? The SoC only has

Can you make these trace strings a bit more in line with the style
for other trace strings, please (i.e. lose the caps and =======) ?

Don't use bitfields in models of hardware (either of
register layouts or of in-guest-memory data), please.
It's not portable (bitfield layout depends on endianness,
plus on Windows the layout of structs with bitfields isn't
the same as GCC's normal standard).
Use normal-sized uint32_t values, and extract subfields
with bitfield ops. include/hw/registerfields.h has some
useful macros you can use where you define the fields in
a register, and then can get at them with eg
bool enable = FIELD_EX32(s->ctrl, CTRL, ENABLE);

As with the other device, my suggestion is to put the
vmstate struct definition in the same patch as the
fields are added to the device state struct.

If the RNG is disabled, is the interrupt line still asserted?
If not, we need to check the rng-enabled bit here and also
make sure we do an update-irq call when that bit of the control
register changes.

Copying from a byte buffer into a uint32_t like this isn't
endianness-safe. fifo8_pop_buf() also won't give you all
the data in the fifo if it happens to be wrapping around the
end of the ring buffer. You can rely on it returning
you at least some data, though, so the NULL check is not
needed. So you want something like:
uint32_t to_read = MIN(fifo8_num_used(fifo), 4);
uint8_t byte_buf[4] = {};
uint8_t *p = byte_buf;
while (to_read) {
buf = fifo8_pop_buf(fifo, to_read, &num);
memcpy(p, buf, num);
p += num;
to_read -= num;
}
ret = ldl_le_p(byte_buf);
(assuming that the hardware spec is that the first bytes
out of the fifo go in the least-significant word of the
result when there isn't enough to fill a full word.)

This looks like it ought to be folded into some other patch, assuming
we keep the property at all.

These "add the rng device to the SoC" changes should be in their
own patch.

What is this timer being used for, and why do we need it?
(This is a good example of the kind of thing to put into a
commit message.) It looks like it's trying to simulate the
way that real hardware only slowly fills up the RNG fifo.
But do we really need the extra complication? Does guest
software fall over if it finds that the FIFO is
full very quickly rather than taking a longer time?

This comment doesn't seem right. BCM2838_THERMAL_SIZE is larger
than 4, so we can have more than one possible address accessed,
even if the address must be aligned. So the warning is
OK, but the g_assert_reached() and the comment are not.

We usually use a LOG_GUEST_ERROR for this kind of "access
with an address that doesn't correspond to a register".

You need to provide a .write, even if it just does a
LOG_GUEST_ERROR for every access. Otherwise if the guest
tries to write then QEMU will crash trying to call the NULL
pointer.

You don't need to set up a vmstate if it has no data.

You can add a comment here:
/* This device has no state: no need for vmstate or reset */
to tell the reader you haven't forgotten it.

Just say 4, please. Do you definitely need to support
all of 1, 2 and 4 byte accesses? (The implementation gets
more painful then.)

%ld in a printf format string for some type other than "long" isn't
portable -- long is 4 bytes on 32-bit hosts and 8 bytes on 64-bit
hosts, so depending on what you passed it tends not to compile.
Always use the right format string for the type you're printing.
For a ssize_t type that is "%zd".

Why is this attribute(packed) ? You almost certainly do
not want this, especially given it's a byte buffer anyway.

Don't try to use bitfields to represent guest register layout
or in-memory data, please -- it's not portable or endian safe.

Better not to use packed structs for that either.

'long' type in a packed struct ? Sounds fishy...
'long' type for any kind of address is also generally
not the correct type.

What is this state doing here ? It looks like the property is
supposed to be changing the handling of GPIOs, but in that case
we should wire the properties through to a gpio device, not
just keep hold of the values written here. Simpler would be
to ignore writes if we don't care to implement it properly.
Otherwise the state needs to live in some device and be handled
on vmsave, reset, etc.

Shouldn't this return the same values as the existing
RPI_FWREQ_FRAMEBUFFER_GET_PHYSICAL_WIDTH_HEIGHT etc etc properties,
rather than hardcoded constant values ?

What is setting the pitch supposed to do? At the moment we
assume it's a fixed value depending on the xres, xres_virtual
and bpp (see bcm2835_fb_get_pitch()), so if the guest can
arbitrarily set it then we need to change something in our
display device model. Failing that we should maybe LOG_UNIMP
any attempt by the guest to set it.

Thanks for doing this -- I really like the way the split
has turned out, and the overall structure of the patchseries
is good. I'm going through the patches individually
(which will probably take me into next week to finish)
but I'm not seeing anything major, just some smaller
issues.

I got through the second half of the patchset faster
than I expected, so I'm now done with my first pass
review of it. Please let me know if you have any
questions about my comments/suggestions on the
individual patches.

Introducing Raspberry Pi 4B model.
It contains new BCM2838 SoC, PCIE subsystem,
RNG200, Thermal sensor and Genet network controller.
It can work with recent linux kernels 6.x.x.
Two avocado tests was added to check that.
Unit tests has been made as read/write operations
via mailbox properties.
Genet integration test is under development.
Every single commit
1) builds without errors
2) passes regression tests
3) passes style check*
*the only exception is bcm2838-mbox-property-test.c file
containing heavy macros usage which cause a lot of
false-positives of checkpatch.pl.
I did my best to keep the commits less than 200 changes,
but had to make some of them a bit more in order to
keep their integrity.
This is v2 patchset with the most of v1 remarks fixed.

Subject: [PATCH 12/45] Temporarily disable unimplemented rpi4b devices
This commit adds RPi4B device tree modifications:
- disable pcie, rng200, thermal sensor and genet devices
(they're going to be re-enabled in the following commits)
- create additional memory region in device tree
if RAM amount exceeds VC base address.

Introducing Raspberry Pi 4B model.
It contains new BCM2838 SoC, PCIE subsystem,
RNG200, Thermal sensor and Genet network controller.
It can work with recent linux kernels 6.x.x.
Two avocado tests was added to check that.
Unit tests has been made as read/write operations
via mailbox properties.
Genet integration test is under development.
Every single commit
1) builds without errors
2) passes regression tests
3) passes style check*
*the only exception is bcm2838-mbox-property-test.c file
containing heavy macros usage which cause a lot of
false-positives of checkpatch.pl.
I did my best to keep the commits less than 200 changes,
but had to make some of them a bit more in order to
keep their integrity.
This is v2 patchset with the most of v1 remarks fixed.

This commit adds RPi4B device tree modifications:
- disable pcie, rng200, thermal sensor and genet devices
(they're going to be re-enabled in the following commits)
- create additional memory region in device tree
if RAM amount exceeds VC base address.

Introducing Raspberry Pi 4B model.
It contains new BCM2838 SoC, PCIE subsystem,
RNG200, Thermal sensor and Genet network controller.
It can work with recent linux kernels 6.x.x.
Two avocado tests was added to check that.
Unit tests has been made as read/write operations
via mailbox properties.
Genet integration test is under development.
Every single commit
1) builds without errors
2) passes regression tests
3) passes style check*
*the only exception is bcm2838-mbox-property-test.c file
containing heavy macros usage which cause a lot of
false-positives of checkpatch.pl.
I did my best to keep the commits less than 200 changes,
but had to make some of them a bit more in order to
keep their integrity.
This is v2 patchset with the most of v1 remarks fixed.
I named it as 'v3' because of mistakes while attempts to send v2 patchset.
Please remove all other v1 and v2 patchsets except the very first one.

0 siblings, 1 reply; 216+ messages in thread
From: Sergey Kambalin @ 2023-12-03 21:48 UTC (permalink / raw)
To: qemu-arm; +Cc: qemu-devel, Sergey Kambalin
This commit adds RPi4B device tree modifications:
- disable pcie, rng200, thermal sensor and genet devices
(they're going to be re-enabled in the following commits)
- create additional memory region in device tree
if RAM amount exceeds VC base address.

Introducing Raspberry Pi 4B model.
It contains new BCM2838 SoC, PCIE subsystem,
RNG200, Thermal sensor and Genet network controller.
It can work with recent linux kernels 6.x.x.
Two avocado tests was added to check that.
Unit tests has been made as read/write operations
via mailbox properties.
Genet integration test is under development.
Every single commit
1) builds without errors
2) passes regression tests
3) passes style check*
*the only exception is bcm2838-mbox-property-test.c file
containing heavy macros usage which cause a lot of
false-positives of checkpatch.pl.
I did my best to keep the commits less than 200 changes,
but had to make some of them a bit more in order to
keep their integrity.
This is v2 patchset with the most of v1 remarks fixed.
I named it as 'v3' because of mistakes while attempts to send v2 patchset.
Please remove all other v1 and v2 patchsets except the very first one.

This commit adds RPi4B device tree modifications:
- disable pcie, rng200, thermal sensor and genet devices
(they're going to be re-enabled in the following commits)
- create additional memory region in device tree
if RAM amount exceeds VC base address.
