Since Linux'es ab66dcc76d "powerpc: generate uapi header and system call
table files" there are 2 new files: unistd_32.h and unistd_64.h. These
files content is moved from unistd.h so now we have to copy new files
as well, just like we already do for other architectures; this does it
for MIPS as well.
Also, v5.0-rc2 moved vhost bits around in 4b86713236e4bd
"vhost: split structs into a separate header file", add those too.

I think this fix is handled by commit a0a6ef91a4a4edde27
(now in master), yes ?

+/**
+ * DOC: overview
+ *
+ * In the DRM subsystem, framebuffer pixel formats are described using the
+ * fourcc codes defined in `include/uapi/drm/drm_fourcc.h`. In addition to the
+ * fourcc code, a Format Modifier may optionally be provided, in order to
+ * further describe the buffer's format - for example tiling or compression.
+ *
+ * Format Modifiers
+ * ----------------
+ *
+ * Format modifiers are used in conjunction with a fourcc code, forming a
+ * unique fourcc:modifier pair. This format:modifier pair must fully define the
+ * format and data layout of the buffer, and should be the only way to describe
+ * that particular buffer.
+ *
+ * Having multiple fourcc:modifier pairs which describe the same layout should
+ * be avoided, as such aliases run the risk of different drivers exposing
+ * different names for the same data format, forcing userspace to understand
+ * that they are aliases.
+ *
+ * Format modifiers may change any property of the buffer, including the number
+ * of planes and/or the required allocation size. Format modifiers are
+ * vendor-namespaced, and as such the relationship between a fourcc code and a
+ * modifier is specific to the modifer being used. For example, some modifiers
+ * may preserve meaning - such as number of planes - from the fourcc code,
+ * whereas others may not.
+ *
+ * Vendors should document their modifier usage in as much detail as
+ * possible, to ensure maximum compatibility across devices, drivers and
+ * applications.
+ *
+ * The authoritative list of format modifier codes is found in
+ * `include/uapi/drm/drm_fourcc.h`

You set nodename immediately below, so no need for the NULL initialization here.

I think error handling (ie whether we print messages or not) ought to be
done by the calling function, rather than here.
> + if (numa_node_id < 0) {
What is this for? My original theory was that this was an error
case that should probably be an assert(), but we seem to use it
in one of the callers below. A brief comment at the top of the
function documenting its API would assist here. If this is
"only set the NUMA ID if it is specified" then I think writing it as
if (numa_node_id >= 0) {
set the id;
}
is clearer than making it look like an error-exit check.

In the prospect to introduce an extended memory map supporting more
RAM, let's split the memory map array into two parts:
- the former a15memmap contains regions below and including the RAM
- extended_memmap, only initialized with entries located after the RAM.
Only the size of the region is initialized there since their base
address will be dynamically computed, depending on the top of the
RAM (initial RAM at the moment), with same alignment as their size.
This new split will allow to grow the RAM size without changing the
description of the high regions.
The patch also moves the memory map setup into machvirt_init().
The rationale is the memory map will be soon affected by the
kvm_type() call that happens after virt_instance_init() and
before machvirt_init().
At that point the memory map is not changed, ie. the initial RAM can
grow up to 256GiB. Then come the high IO regions with same layout as
before.

This change makes it clear that "a15memmap" is badly misnamed.
I think we should change it to "base_memmap" here.

I think you should say here that if there is less than 256GiB of RAM
then the floating area starts at the 256GiB mark.

On ARM, the kvm_type will be resolved by querying the KVMState.
Let's add the MachineState handle to the callback so that we
can retrieve the KVMState handle. in kvm_init, when the callback
is called, the kvm_state variable is not yet set.

Can you add a line to the struct's documentation comment for the
@kvm_type field, please ?
We're rather inconsistent about what we name the MachineState*
parameter in methods here:
"state" x 1 (init)
"machine" x 3 (get_hotplug_handler, cpu_index_to_instance_props,
possible_cpu_arch_ids)
"ms" x 1 (get_default_cpu_node_id)
It would probably be better to follow the most common option
rather than one of the rarer ones.
Otherwise

Add the kvm_arm_get_max_vm_phys_shift() helper that returns the
log of the maximum IPA size supported by KVM. This capability
needs to be known to create the VM with a specific IPA max size
(kvm_type passed along KVM_CREATE_VM ioctl.

This is the number of bits in the IPA address space,
right (ie 40 for a 40-bit IPA, and so on) ? If so, then
I think "Return number of bits in the IPA address space"
might be clearer.

It actually returns the MAX number of bits in the IPA address space
supported by the host kernel. What about naming this function
"kvm_arm_get_max_vm_ipa_size".

The machine RAM attributes will need to be analyzed during the
configure_accelerator() process. especially kvm_type() arm64
machine callback will use them to know how many IPA/GPA bits are
needed to model the whole RAM range. So let's assign those machine
state fields before calling configure_accelerator.

This is still after the call to set_memory_options(), so it's OK.

This patch implements the machine class kvm_type() callback.
It returns the max IPA shift needed to implement the whole GPA
range including the RAM and IO regions located beyond.
The returned value in passed though the KVM_CREATE_VM ioctl and
this allows KVM to set the stage2 tables dynamically.
At this stage the RAM limit still is limited to 255GB.
Setting all the existing highmem IO regions beyond the RAM
allows to have a single contiguous RAM region (initial RAM and
possible hotpluggable device memory). That way we do not need
to do invasive changes in the EDK2 FW to support a dynamic
RAM base.

Presumably we should have some equivalent check for TCG, so
that we don't let the user create a setup which wants more
bits of physical address than the TCG CPU allows ?

When is there a difference between setting this to NULL,
and setting it to virt_kvm_type but having the memory
size be <= 256GiB ?
If there isn't any difference, why can't we just let the
pre-4.0 versions behave like the new ones? No existing
VM setup will have > 256GB of memory, so as long as there's
no behaviour change for the <=256GB case we don't need to
take special effort to ensure that the >256GB case continues
to give an error message, do we ?

My intent was to align the start of the device memory on a GiB boundary,
just after the initial RAM (ram_size). And then align the floating IO
region on a GiB boundary after the device memory (of size
ms->maxram_size - ms->ram_size). What do I miss?

kvm_type() sets the new memory map. For TCG we should stick to the 1TB
GPA address space which should be consistent with the existing
ID_AA64MMFR0_EL1 settings (arm/internals.h implements arm_pamax(ARMCPU
*cpu) which decodes hardcoded cpu->id_aa64mmfr0).

There shouldn't be any difference. When size <= 255GiB we stick to the
1TB PA address space.

But don't we want to forbid any pre-4.0 machvirt to run with more than
255GiB RAM?

It's not obvious what "GiB + ms->ram_size" means and where it comes from,
maybe substitute GiB with properly named constant/macro that's also re-used in
memmap definition so it would be obvious that's it's where initial RAM
is mapped. Also I'd move both ROUND_UPs into separate expressions using
reasonable named local vars and possible overflow checks on top of that,
so one won't have to guess that it's initial RAM end + device RAM end.

it's quite confusing, you have vms->extended_memmap and mc->kvm_type and
the later for some reason enables device memory.
to me it seems that both are not related, device memory should work just fine
without kvm nor dynamic IPA (within TCG supported limits).
I'd make extended_memmap virt machine class member the will enable pc-dimm support
and then it add checks for supported IPA range on top

I agree I did not take into account the TCG use case and this series
does not enable device memory with TCG which is a pitty. I will
decorrelate things.

Now we have the extended memory map (high IO regions beyond the
scalable RAM) and dynamic IPA range support at KVM/ARM level
we can bump the legacy 255GB initial RAM limit. The actual maximum
RAM size now depends on the physical CPU and host kernel.

Please note that this will soon change with
[PATCH RFCv2 0/9] qdev: Hotplug handler chaining + virtio-pmem
What you'll have to do then is to replace the object_unparent by a
object_property_set_bool(OBJECT(dev), false, "realized", NULL);

This patch add memory nodes corresponding to PC-DIMM regions.
NV_DIMM and ACPI_NVDIMM configs are not yet set for ARM so we
don't need to care about NV-DIMM at this stage.

error message is rather vague, user using nvdimms + pc-dimms on CLI won't have
a clue that the former is not supported.
Suggest pass in error_fatal as argument and report more specific error from
fdt_add_hotpluggable_memory_nodes()
does this run on reboot?

Yes after a QMP system_reset I can see the DIMMS on guest in /proc/meminfo

it siims that dimms come from ACPI and not DTB.
My worry was that arm_load_dtb() always end up with exit(1) on failure but it seems
that it's not called on reboot so it should be fine.

I don't understand the computation done in pc machine. eventually we are
likely to have more device memory than requested by the user. Why don't
we check (machine->maxram_size - machine->ram_size) >=
machine->ram_slots * GiB
instead of adding 1GiB/slot to the initial user requirements?
Also machine->maxram_size - machine->ram_size is checked to be aligned
with TARGET_PAGE_SIZE. Is TARGET_PAGE_SIZE representative of the guest
PAGE in accelerated mode? Is it valid ro require an alignment on 1GB
boundary as I do in this patch?

This is to be able to potentially align each slot as far as I know, so
the "memory device address space" cannot that easily be fragmented.
E.g. Linux requires a certain alignment to make full use of a DIMM.

I guess the alignment check is only done because for that target,
anything having sub-page granularity cannot be used either way.

See commit 085f8e88b for explanation,
What we are basically are doing there is sizing hotpluggbale address space
to allow max possible huge page aligned DIMM to be successfully plugged in
even if address space if fragmented.

In v7, I also added ram_slots * GiB to (maxram_size - ram_size).

Depending on the way the system handles it, this might be confusing for
the end user and has to be documented somewhere.
E.g. if there are certain memory limits (say 2TB) and the user specifies
something like "maxmem=2TB,slots=20" it might be confusing if he gets an
error like "more than 2TB are not supported".

I Agree. On ARM we also intend to put high IO regions above the RAM so
if we overshoot the host limit, we warn the user the memory map requires
more PA bits than the host can support and the end user is invited to
lower maxmem/slots.

This patch uses configurable IO base and size to create NPIO AML for
ACPI NFIT. Since a different architecture like AArch64 does not use
port-mapped IO, a configurable IO base is required to create correct
mapping of ACPI IO address and size.

I understand it can be anywhere in low mem and must be large enough to
contain [NVDIMM_ACPI_IO_BASE, NDIMM_ACPI_IO_BASE + NVDIMM_ACPI_IO_LEN].
So one 64kB page should do the job?
Thanks

it looked to like generic ACPI arrea rather than NVDIMM
so I'd suggest to name it properly and probably use NVDIMM_ACPI_IO_BASE & co
to add this entry so that reader won't have to wonder where this magic numbers
come from.

Should it be located in lowmem?
(do we care about device_memory & AVMF & ACPI & not 64bit guests?)

OK. I will rename the region in v8

I guess no. We could easily fit this region into the existing low mem
IO, that's what I meant actually.

Hi Eric; sorry I haven't reviewed this series earlier. I think
that 1-10 are pretty near to ready to go in; maybe the easiest
path is to do a respin of just those with the review issues fixed?
I'm a long way from being expert in the PC-DIMM/NV-DIMM stuff, so
I'm going to be reliant on other people to review those parts.
I don't know if your series needs anything from linux-headers
which isn't already in QEMU master after the update to match
5.0rc1 -- if not you could drop the header-sync patch.
thanks

No problem. Thank you for the review.
Yes I will quickly respin the patches you reviewed.

5.0-rc1 should be OK so I think I can drop the header sync.
