In Restricted CXL Device (RCD) mode (formerly referred to as CXL 1.1)
the PCIe enumeration hierarchy is different from CXL VH Enumeration
(formerly referred to as 2.0, for both modes see CXL spec 3.0: 9.11
and 9.12, [1]). This series adds support for RCD mode. It implements
the detection of Restricted CXL Hosts (RCHs) and its corresponding
Restricted CXL Devices (RCDs). It does the necessary enumeration of
ports and connects the endpoints. With all the plumbing an RCH/RCD
pair is registered at the Linux CXL bus and becomes visible in sysfs
in the same way as CXL VH hosts and devices do already. RCDs are
brought up as CXL endpoints and bound to subsequent drivers such as
cxl_mem.

For CXL VH the host driver (cxl_acpi) starts host bridge discovery
once the ACPI0017 CXL root device is detected and then searches for
ACPI0016 host bridges to enable CXL. In RCD mode an ACPI0017 device
might not necessarily exist and the host bridge can have a standard
PCIe host bridge PNP0A08 ID, there aren't any CXL port or switches in
the PCIe hierarchy visible. As such the RCD mode enumeration and host
discovery is very different from CXL VH. See patch #5 for
implementation details.

This implementation expects the host's downstream and upstream port
RCRBs base address being reported by firmware using the optional CEDT
CHBS entry of the host bridge (see CXL spec 3.0, 9.17.1.2).

RCD mode does not support hot-plug, so host discovery is at boot time
only.

Patches #1 to #4 are prerequisites of the series with fixes needed and
a rework of debug messages for port enumeration. Those are general
patches and could be applied earlier and independently from the rest
assuming there are no objections with them. Patches #5 to #15 contain
the actual implementation of RCD mode support.

The function devm_cxl_iomap_block() is only used in the core
code. There are two declarations in header files of it, in
drivers/cxl/core/core.h and drivers/cxl/cxl.h. Remove its unused
declaration in drivers/cxl/cxl.h.

There is this 0day test bot warning and I will need to either extend
this patch or add another one to fix regs.c.

Yes, for my Reviewed-by: small fixups that don't touch the core theme of
the patch are ok.

The physical base address of a CXL range can be invalid and is then
set to CXL_RESOURCE_NONE. Early check this case before mapping a
memory block in devm_cxl_iomap_block().

An example of when it is invalid would be a useful addition
to this description.  Feels to me like this is papering over the cracks
in something we should have ruled out earlier in the flow.

IIRC this happened during code development in cxl_pci_probe() when
cxl_map_regs() is called but the base addr was not determined
correctly before. It's similar to a NULL pointer check.

devm_request_mem_region() succeeds for you when this happens? More
details about the failure scenario please.

No, CXL_RESOURCE_NONE (all FFs) is used as address. A broken range is
calculated that even overflows. I only vaguely remember the exact
error message.

This may happen e.g. if the Component Register Block is missing in the
DVSEC. cxl_find_regblock() may fail then and returns
CXL_RESOURCE_NONE. There are a couple of code paths there
component_reg_phys is set to CXL_RESOURCE_NONE without exiting
immediately.

I saw it during code development, when I pre-inititalized a port with
component_reg_phys set to CXL_RESOURCE_NONE. Since that case can
generally happen, I think it must be checked.

I think Jonathan had it right when we posited that the code should
probably have failed before getting to this point. For example, the
scenarios where the driver looks for a component register block via the
register locator DVSEC are not valid for RCDs in the first instance.

I am ok having the code reviewed to prevent such situations. But the
handling of component_reg_phys is by far not trivial as there are many
locations it is initialized and others where it is used. Call chain is
across multiple functions using various data sources for
component_reg_phys, so it is hard to proof this may never happen.
E.g. in add_port_attach_ep() I found this:

	component_reg_phys = find_component_registers(uport_dev);
	port = devm_cxl_add_port(&parent_port->dev, uport_dev,
        	component_reg_phys, parent_dport);

find_component_registers() and subsequent functions (e.g.
cxl_regmap_to_base()) may return CXL_RESOURCE_NONE. But it is written
to port without any further check in cxl_port_alloc():

	port->component_reg_phys = component_reg_phys;

It is then later directly used in devm_cxl_setup_hdm() to map io
ranges with devm_cxl_iomap_block().

Just an example, I did not go through other code paths.

IMO, the check is cheap and prevents weird follow up errors and log
messages. But I would be also ok, to just drop the patch. There are no
dependencies to this change. What do you think?

Thanks,

-Robert

Good points above...

Yeah, the expectation is that only "broken hardware" fails to provide
component registers, but the driver is currently deficient in that it
assumes everything is CXL 2.0.

Now you have me thinking it should go a bit further and do a WARN_ONCE()
when CXL_RESOURCE_NONE is passed, as those locations need better error
handling than just handling it like an ioremap() failure.

CXL ports are added in a couple of code paths using
devm_cxl_add_port(). Debug messages are individually generated, but
are incomplete and inconsistent. Change this by moving its generation
to devm_cxl_add_port(). This unifies the messages and reduces code
duplication. Also, generate messages on failure.

This is one for Dan etc as it is mostly a question of how verbose we want
the debug prints to be plus preference for caller or callee being
responsible for outputting this sort of message.

Patch looks good to me if we want to make this sort of change.

Esp. together with dyndbg this is very useful as you can get a whole
picture of the port enablement.

While I agree this unifies the error messaging I am not a fan of what
this does to the readability of the error exits. What about a compromise
of renaming devm_cxl_add_port to __devm_cxl_add_port() and add back a
new devm_cxl_add_port that does the unified debug messaging?

Ok, will add a wrapper.

CXL dports are added in a couple of code paths using
devm_cxl_add_dport(). Debug messages are individually generated, but
are incomplete and inconsistent. Change this by moving its generation
to devm_cxl_add_dport(). This unifies the messages and reduces code
duplication. Also, generate messages on failure.

Similar comment as before of using a goto just to ensure the log message
is called, I suspect a wrapper to do the logging ends up with less code
thrash.

Restricted CXL device (RCD) mode (formerly CXL 1.1) uses a different
enumeration scheme other than CXL VH (formerly CXL 2.0). In RCD mode a
host/device (RCH-RCD) pair shows up as a legal PCIe hierarchy with an
ACPI host bridge ("PNP0A08" or "ACPI0016" HID) and RCiEP connected to
it with a description of the CXL device.

Add function cxl_restricted_host_probe() to probe RCD enumerated
devices. The function implements a loop that detects all CXL capable
ACPI PCI root bridges in the system (RCD mode only). The iterator
function cxl_find_next_rch() is introduced to walk through all of the
CXL hosts. The loop will then enable all CXL devices connected to the
host. For now, only implement an empty loop with an iterator that
returns all pci host bridges in the system.

The probe function is triggered by adding an own root device for RCHs.
This is different to CXL VH where an ACPI "ACPI0017" root device
exists. Its detection starts the CXL host detection. In RCD mode such
a device does not necessarily exists, so solve this by creating a
plain platform device that is not an ACPI device and is root only for
RCHs.

If I read this correctly that platform device is created whether or not
there are any cxl devices in the system?

Can we create it only if we find some devices that will be placed
under it later?

Why the empty release?  Perhaps introduce this only when it
does something.

This would move the host detection from probe to init which I wanted
to avoid to better control driver init order dependencies.

I could add a put_device() at the end of a probe so that it will be
released in case no other references use it. This implies the refcount
is maintained for parent devices. Or this needs to be added to. So if
there are no children (hosts) attached to the root device after probe,
it will disappear.

The core device driver requires this in device_release() to be setup.

There is nothing to do as the device is kept in a static struct.
That's why it's empty.

It's a bit nasty either way.  I can see your reasoning, but
definitely not keen on it if there is a plausible way to avoid.

Unless there is precedence for that, it'll be weird enough to be
hard to maintain.  I guess I can live with the ugliness if we can't
add something new to ACPI to base this off.

Ah got it. I'd failed to register the static structure.

Let's stay with a put_device() for now. Then, we wont have a stale cxl
root device in the system in case there are no RCD children.

Kind of obvious, but...
Make sure to call that out as an unusual thing to do via cover letter / patch
description so we hopefully get more eyes on this detail..

Drive-by nitpicks: 
s/PCI root bridges/PCI host bridges/ to match other uses
s/pci host bridges/PCI host bridges/ to match other "PCI" uses

As I mentioned in the cover letter a BIOS that does not provide an
ACPI0017 device is opting out of the possibility OS first error handling
and other OS CXL services. ACPI0017 is mandatory.

Otherwise, its odd to have a module create the device that its driver is
going to drive. That's a backwards driver model and why we proposed
ACPI0017 in the first instance.

These host bridges should be discovered by add_host_bridge_dport(), no?
Unless the BIOS is failing to emit the expected CEDT along with
ACPI0017.

A lookup of a host bridge's corresponding acpi device (struct
acpi_device) is not possible, for example:

	adev = ACPI_COMPANION(&host_bridge->dev);

This could be useful to find a host bridge's fwnode handle and to
determine and call additional host bridge ACPI parameters and methods
such as HID/CID or _UID.

Make this work by linking the host bridge to its ACPI fw node.

Seems sensible to me, though I'm not an expert in this are of the code.

s/acpi device/ACPI device/ to match other "ACPI" usage
s/fw node/fwnode/ (if it should match "fwnode handle" above)

I guess this patch makes ACPI_COMPANION() work where it didn't before,
right?  E.g., the two ACPI_COMPANION() uses added by this series
(cxl_find_next_rch() and cxl_restricted_host_probe()).

I'm not really clear on the strategy of when we should use acpi_device
vs acpi_handle, but does this mean there's code in places like
pci_root.c that should be reworked to take advantage of this?  That
code evaluates _DSM and _OSC, but I think it currently uses
acpi_handle for that.

acpi_handle should be used for interactions with the ACPICA code, like
when AML is evaluated, and acpi_device for pretty much everything
else.

When is this explicitly needed. "Could be useful" is interesting, but it
needs to have a practical need.

It is needed and it is present on x86 AFAICS (see my last reply in this thread).

This seems to be addressing an ARM64-specific issue.

No, it is x86. And true, it is set. So this series is actually working
without this patch. It can be dropped.

Now, I just checked my logs. The reason I was adding this is that
during code development I modified the code to have bridge->dev.parent
set. Then, the fwnode is not linked. I later dropped that change but
kept this patch.

Thanks for catching this.

If this patch does the same thing as the ACPI_COMPANION_SET() in
several pcibios_root_bridge_prepare() implementations, I would love to
keep this patch, which does it in a generic place, and drop the
corresponding code from those arch-specific functions.

But I don't understand the fwnode stuff well enough to know if this is
feasible.

I took a brief look, but I could not convince myself that these lookups:

arch/ia64/pci/pci.c ((struct pci_controller *) bridge->bus->sysdata)->companion
arch/loongarch/pci/acpi.c to_acpi_device(((struct pci_config_window *) bridge->bus->sysdata)->parent)
arch/arm64/kernel/pci.c to_acpi_device(((struct pci_config_window *) bridge->bus->sysdata)->parent)
arch/x86/pci/acpi.c ((struct pci_sysdata *) bridge->bus->sysdata)->companion

...are identical to what acpi_pci_root_add() used to create the
acpi_pci_root.

Hmm.

x86 has this code in pcibios_root_bridge_prepare():

    if (!bridge->dev.parent) {
        struct pci_sysdata *sd = bridge->bus->sysdata;
        ACPI_COMPANION_SET(&bridge->dev, sd->companion);
    }

which should set the ACPI companion for the host bridge.

Moreover, on my x86 desktop /sys/devices/pci0000\:00/ (which is the
host bridge AFAICS) has

firmware_node -> ../LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00

so clearly the ACPI companion is there.

Are we talking about ARM64 here?

So this would be replacing the existing mechanism on x86, right?

An RCH is a root bridge and has "PNP0A08" or "ACPI0016" ACPI ID set.
Check this.

Hi Robert,

I'm a little uncomfortable with repurposing acpi_device_id
as you have done here.  Might be better to do the same
as in pci_root.c where the matches are done more directly.

Trivial but no comma after a null terminator.   Always good to make
it harder for people to add things where they really shouldn't!

pci_root.c avoids using an acpi_device_id table for similar matching.
I think the point being to separate probe type use of this table
from cases where we aren't using a normal device probe.
So to remain consistent with that, I would just grab the hid
and match it directly in this code.

I don't feel that strongly about this if the ACPI maintainers are
fine with reusing this infrastructure as you have it here.

Can do this.

Grabbing the hid only is actually a violation of the acpi spec as a
cid could be used interchangeable. It must also work then.

It is also not possible to use something like probe or a handler
matching the ids because the hosts must be enabled with the already
existing drivers and handlers. Suppose there are multiple handlers for
the same ids, the first handler wins and all other never get called.

To me it looks sane and simple to use acpi_match_device_ids() here.

Ok. One for the ACPI maintainers to comment on if they wish - I'm fine with this

Again, finding all the ACPI0016 devices is add_host_bridge_dport()
already does.

An RCH has an RCiEP connected to it with CXL DVSEC capabilities
present and the CXL PCIe DVSEC included. Check this.

So assumption here is that the hostbridge has a one or more RCiEPs.
The spec (r3.0 9.11.4) allows for the EP to appear behind a root port
- that case always felt odd to me, so I'm fine with not supporting it until
we see a user.

Thinking a bit more on this.  I'm not sure this is sufficient.
Nothing in CXL 2.0 or later prevents true RCiEP devices (there are a
few references in CXL 3.0 e.g. 9.12.1 has RCDs or CXL RCiEPs - so just
detecting that there is one on the host bridge might not be sufficient
to distinguish this from a non RCH / RCB.

An RCD has its own host bridge created (software view, not the phys
topology). Host and device are paired in this case. Non-RCDs are
standard endpoints and not RCiEPs, they have their own host. There
cannot be both types connected to the same host.

Again, see figure 9-12 and 9-13.

I disagree. CXL spec does not exclude the possibility of real CXL
RCiEPs. So a CXL 2.0+ device that talks CXL configuration for some
reason but is part of the root complex itself (maybe a chiplet or
something where there isn't necessarily a real CXL bus involved).
Same reason we have RCiEPs in normal PCIe.

Chasing references - there is only one I can find (CXL r3.0 9.12.1)
"If a Host bridge is not associated with RCDs or CXL RCiEPs."

Both listed because they are different things.
(I think it's fine to say here that this has been queried in
appropriate place in the past and is something that is allowed).

So I still don't think the above check is sufficient'. If you
happen to have just one CXL 2.0+ RCiEP on a host bridge with
not root ports, then the check will identify it as a restriced
host.  Maybe I'm missing another check that wouldn't though....

Examples - don't show all the crazy things people are allowed to 
build - you would need an awful lot of diagrams to do that.

Right, there are references to CXL 2.0+ devices implemented as RCiEPs.

"9.12 CXL VH Enumeration" states that for the CXL Host Bridge
identification the CEDT should be used:

"""
CXL Early Discovery Table (CEDT) may be used to differentiate
between the three software concepts listed above.
"""

This check is added in patch #10 where the RCRB is extracted, so we
are good here.

The software view of an RCD is always the same, it shows up always as
an RCiEP. See figure 9-12 and 9-13 of the spec.

Ah. I see I misread the following from CXL r3.0 9.11.4 

"This ACPI Host Bridge spawns a legal PCIe hierarchy. All PCIe Endpoints located in the 
RCD are children of this ACPI Host Bridge. These Endpoints may appear directly on the 
Root bus number or may appear behind a Root Port located on the Root bus."

I guess that is allowing 'additional' PCIe endpoints below a root port attached
to the ACPI Host Bridge, but not dev 0 func 0.  That's a subtle distinction
I missed.

The check looks good, just the matter of integrating it into the
existing ACPI0016 device detection.

The UID is needed to read the RCH's CEDT entry with the RCRB base
address. Determine the host's UID from its ACPI fw node.

There is an acpi_device_uid() accessor function that should probably be
used here.

Also, should a fialure to convert to an integer (or one within
limits) be something we paper over?  Feels like we should fail
hard if that happens.

Admittedly I can't immediately find any spec that states that
the _UID should be either integer or under 32 bits...
ACPI allows a string and CXL just says it's 4 bytes long.

That accessor actually does not help really, there is no null pointer
check for adev. Using it actually adds more complexity since another
variable is introduced plus you need to look at the function's
implementation anyway.

The adev->pnp.unique_id access pattern is widely used in the kernel, I
don't expect changes in the data struct here.

This is a real corner case and close to a broken firmware
implementation. I think current dbg messages are good to find where
the detection stops.

IIRC the UID can be implemented as string or 8 bytes, there is no
limitation then. That's why the range check below.

Hmm. I don't like papering over such bugs as it leads to people not
fixing their bios as early as they otherwise would,
	but fair enough I guess.

The UID field holds 4 bytes of ASCII characters. kstrtoull() would fail
if the UID field has value such as ‘CX03’.

The UID field is not 4 ASCII characters.

We went through this before in the original code in
drivers/cxl/acpi.c::add_host_bridge_dport().

The CEDT.CHBS defines _UID as an integer so use acpi_evaluate_integer()
to retrieve the UID to perform the comparison. I thought there was an
errata filed to clarify this, but it seems the current spec still just
says "value". The CFMWS also places _UID values in the target list,
those are also handled as integers.

ACPI 6.4 spec section 6.1.12 describes _UID, it says the return value is:
An Integer or String containing the Unique ID.

In the BIOS I see, the _UIDs of PCIe devices hold ASCII characters (not NULL
terminated).

ASCII characters without NULL termination means that data can be
treated as binary data which is what current CFMWWS parsing code chooses
to do. I think a spec clarification is needed to make resolve the
ambiguity.

Agreed. In this case, ACPI spec should be referred to.

The downstream and upstream port Root Complex Register Blocks (RCRBs)
are needed to control the ports and CXL devices connected to it. It
also includes the location of the RCH/RCD downstream and upstream port
component registers in MEMBAR0. Extract the RCRB from the host's CEDT
entry.

Some of these could be made local to the while loop to reduce their scope.

I would need to move most of the vars into the loop then. So I rather
want to keep it as it is.

I also remember a compiler or code checker complaining about block
declaration, though it is in the c standard.

A downstream port must be connected to a component register block.
Determine its base address from the RCRB.

The implementation is analog to how cxl_setup_regs() is implemented
for CXL VH mode. A struct cxl_component_reg_map is filled in, mapped
and probed.

A few comments inline.  Mostly requests for references for things
I couldn't find in the specs.

For references include spec version.  Based on discussion other day,
preference is always latest version. So r3.0 8.2.3
is probably right. I think your references are CXL r2.0?

The spec is a bit confusing on this, but I think you are reading into
MEMBAR0 of the RCRB, for which there isn't a lot of description other than
it being an address. It's referred to as a 64-bit BAR in places so you
might be right - or it might be intended to be a bare address..

We might want a clarification on this...

Also it's a 64 bit address so we need to read it in one go. However it's
referred to as a being a 64 bit address at 0x10 and 0x14 so who knows...

The rcrb is 8k though I'm not immediately spotting an alignment requirement,
but I'm not sure the component regs have any restrictions do... Add a reference perhaps?
For non RCD devices there is a 64K alignment requirement, but I can't find
anything for RCDs (might just be missing it).

Add a spec reference for the size. Table 8-21 perhaps?

Hmm. HDM decoder capability is optional for RCDs - might be using the
range registers.  Seems like we'd really want to handle that for
RCDs.  Future work I guess.

Trivial: As before, if we can reduce scope to inside the while loop, slightly cleaner

Perhaps rename to make it clear this is getting the DSP component registers.

Future work would be to add support for the CXL 3.0 feature that lets even an
RCD just put some of these registers in a BAR as per CXL 2.0 devices.

Better to have a more specific error message and return directly above.
Note that so far vast majority of CXL error messages are dev_dbg,
so for consistency perhaps this should be as well.
(I prefer dev_err() but not my subsystem ;)

dev_err_probe() is slightly nicer to use if things can only happen in
probe() paths.

Most of it comes from the pci base spec (5 or 6).

This is part of the pci base spec and clearly defined there. There are
also some similar implementation in the kernel already.

This are the requirements of the pci base spec to membar ranges. The
range size is power of 2 and base must be aligned to its size.

I used the same message as for the non-RCD code path. HDM decoding is
just a subset of features handled with component regs. We need to
generalize the code for this in the future.

There is more verbosity on the errors with dbg enabled. Note there are
only a few dev_info/dev_err messages to not polute the logs. dev_err()
is only used if something unexpected happens (e.g. the device exists
but component regs are broken).

Ok. Extra references appreciated - these specs are huge, so saving

There isn't a cross reference from CXL spec and PCI doesn't use
the term membar.

I guess it is fairly obvious though that it's an abbreviation
of Base Address Register for Memory.  I might raise the wish to tidy that
up for a future spec revision.

Ok.  It feels convoluted to rely on the CXL glossary entry for BAR
to cover MEMBAR0 and hence inherit the restrictions of a PCIe bar.

Maybe just add a comment here so that anyone who hits this can understand
the source of the restriction seeing as it isn't in the CXL spec and this
isn't a PCI BAR.

Sure - much more likely to need that generalized code for an RCD.
IIRC a CXL 2.0 device must implement HDM decoders, even though the
other path can be used by software that doesn't understand CXL 2.0.
Our RCD might be because the device is CXL 1.1...

Ok. I'll leave the question of balance between the two for CXL maintainers
to comment on if they wish.

Yes, this will be a follow on series.

cxl_setup_component_reg() calls cxl_probe_component_regs() which depends on the existence
of HDM decoder capability register. Such register does not exist when the device is in RCRB
mode, attached to a RCH.

RCD mode has a different enumeration scheme other than in CXL VH mode.
An RCD is directly connected to an RCH without downstream and upstream
ports showing up in between in the PCI hierarchy. Skip dport
enumeration for RCHs. Upstream and downstream ports of RCH and RCD
will be setup separately in a later patch.

Introduce the function is_rch_uport() to detect an RCH port. For RCHs
the parent root port is not the "ACPI0017" device and instead does not
have a fw node connected to it.

I'm not keen on the presence of fwnode being used to distinguish anything.
That's the sort of thing that gets 'fixed' by later patches.

Can we check something more specific?

We actually know the parent device is the root device, so we can check
this. Even easier.

RCD mode has a different enumeration scheme other than in CXL VH mode.
An RCD is directly connected to an RCH without downstream and upstream
ports showing up in between in the PCI hierarchy. Due to the direct
connection of RCD and RCH, the host bridge is always the RCD's parent
instead of the grandparent. Modify devm_cxl_enumerate_ports()
respectively.

Implement this by introducing a function to determine the device's
downstream port. The 'for' loop is adjusted for RCD mode and in this
case find_cxl_port() will always find the host's associated port and
the loop iteration stops.

Switching from grandparent to this is a little confusing because it's
done in two steps.  Perhaps use
	return grandparent(cmlmd->dev);
here to keep that connection and rename dev in this function to parent.

Far too many devices in here with similar names for it to be easy
to read.

I don't like looping for the RCD case as it relies a bit too
much on subtle relationships between devices and parent.

Perhaps better to factor out the contents of the loop, then handle
the RCD case separately from the main loop.
I haven't tried it, so perhaps that looks even less readable.

Do the plumbing of ports to enable RCD/RCH pairs.

Do this by enumerating all necessary ports an endpoint needs to
connect to. This includes:

 1) A CXL root port with dport links to the RCHs. The port links to
    the CXL root platform device for RCH mode.

 2) RCH ports with dport links to its endpoints. Port connects to the
    pci host bridge device.

 3) CXL device endpoint connected to the RCH.

The port creation for the endpoint (3) is already implemented and
works in RCD mode too. Thus, it is not scope of this patch. Only the
endpoints must be registered at the host bridge port.

Implement this by introducing the function cxl_enumerate_rch_ports().
It registers a CXL host at the CXL root device, creates the host's
port and registers the existing CXL memory device endpoint at it. The
port of the CXL root device is created with the first CXL host being
registered.

Once enumerated, CXL restricted hosts show up in sysfs with CXL
devices connected as endpoints to it.

There is no component_reg_phys provided here, so the addr is
CXL_RESOURCE_NONE.

Will improve the comment.

In RCD mode the CXL mem dev may be detected on the PCI bus before a
CXL host is brought up. This may cause a CXL mem initialization
failure as it expects the CXL host already detected. Address this by
specifying the module dependencies using MODULE_SOFTDEP().

The following additional dependencies exist:

 * cxl_mem depends on cxl_acpi: The CXL hosts must be discovered
   before the CXL device is initialized.

 * cxl_acpi depends on cxl_port: The acpi driver adds ports to the cxl
   bus, the port driver should be loaded before. This might also work
   if modules are loaded in different order, but a) it aligns with the
   existing cxl_mem/cxl_port softdep and b) it always guarantees a fix
   module load order.

This is not unique to RCD mode. It is mitigated by the cxl_bus_rescan()
at the completion of cxl_acpi_probe().

Why does a fixed module load order matter?

The only reason cxl_acpi would need to preload cxl_port is if it wanted
to do something like:

port = devm_cxl_add_port(...);
if (port->dev.driver)
	/* do something with an enabled port */
else
	/* do something else if the port failed to enable */

There is no strict requirement that CXL topologies be limited to ACPI
platforms. Per above, the cxl_mem driver will attach when the CXL root
device finally appears, and async out-of-order arrival is ok.

Hi Robert,

I'm curious on the aims of this work.  Given expectation for RCDs is often
that the host firmware has set them up before the OS loads, what functionality
do you want to gain by mapping these into the CXL 2.0+ focused infrastructure?

When I did some analysis a while back on CXL 1.1 I was pretty much assuming
that there was no real reason to let the OS know about it because it
couldn't do much of any use with the information.  There are some corners
like RAS where it might be useful or perhaps to enable some of the CXL 3.0
features that are allowed to be EP only and so could be relevant for
an older host (e.g. CPMUs).

With my QEMU hat on I wasn't planning to bother with anything pre 2.0
but it might be worth considering to let us exercise this code...

Jonathan

though CXL RCD works with a legacy kernel or without any CXL
functionality added, a CXL aware kernel can be useful also for RCD
mode. RAS is a topic here but also gathering device information such
as status or topology. Everything where access to the component
register block or mailbox interface is required.

Another plus, the CXL hierarchy becomes visible for RCD mode in sysfs
and the device hierarchy.

Reusing the existing infrastructure for this makes sense. Many
features overlap in both modes (e.g. RAS, mailbox again, or topology
information).

Thanks again for you review.

Unless the BIOS is going actively enable the standard CXL topology with
ACPI0017 then I think it should be hands off for the OS. The maintenance
burden of some of the hack to work around missing BIOS descriptions is
non-trivial, and it is still early days to encourage BIOS vendors to
enable what is needed and set end user expectations that these
pre-requisites exist.

As far as I can see this enabling adds an additional CXL "root" device
and I do not think userspace should need to care if a CXL 2.0 device is
attached to an RCH or not.

RAS only if OS first is supported by the BIOS. Mailbox support happens
with or without a CXL root device. The topology information is certainly
important in OS first error handling, but if its firmware first its
going to have its own FRU id scheme. Much of the common case topology
information for the RCH case (like which RCIEP is hosting which CXL address
range) is covered by this pending lspci update:

https://github.com/pciutils/pciutils/pull/59:

...although that needs some help to get over the goal line.

Otherwise the topology information is mostly for describing all the
degrees of freedom of a full blown CXL 2.0 topoloy with host bridge and
switch interleaving.

Apologies for the delay in getting to this I had hoped to be able to
finish up some other DAX work to focus on this, but time is getting
short so I will need to do both in parallel.

That's a broken BIOS as far as I can see. No ACPI0017 == no OS CXL
services and the CXL aspects of the device need to be 100% managed by
the BIOS. You can still run the cxl_pci driver in that case for mailbox
operation, but error handling must be firmware-first without ACPI0017.

Firmware-first or OS-first applies to CXL protocol error handling. For CXL 
memory error handling, the device generates a DRAM error record, the OS
parses such record and act accordingly. According to CXL spec (section
8.2.9.2.1.2 DRAM Event Record), DPA but not HPA is in such record. The OS
needs to translate such DPA into HPA to act on. I am taking this as an example
to show that OS CXL services is needed.
Instead of using ACPI0016 to tell whether the system is under RCH mode,
I suppose one way is to check “CXL version” field of CHBS structure in CEDT?

Unless the OS has negotiated CXL _OSC the BIOS owns the event retrieval
and translating it from DPA to HPA. I do want to add OS CXL services to
Linux, but only in the case when the BIOS is actively enabling OS native
address translation which includes populating ACPI0017, CFMWS, and
devices with the HDM decoder capability registers instead of DVSEC range
registers. Everything else is early-gen CXL that is 100% BIOS supported,
similar to DDR where a driver is not expected.

It makes sense that the BIOS and OS need to negotiate CXL _OSC so that OS
would take care of address translation. That being said, only DVSEC range 
register (but not HDM decoder capability register) is available when the device is in
RCRB mode (section 9.11.8 figure 9-7) attached to a RCH. This type of
configuration needs to be supported with OS CXL service.

So that figure does have the HDM capabilty pictured in the RCD upstream
port. However, Table 8-22 does seem to incidate that Type 3 D1 devices
are not permitted to have an HDM Decoder Capabilitiy Structure.

However that then leave me confused about figure 9-8 as that shows an
HDM decoder capability in the BAR and not the RCRB. Is that picture
wrong with respect what Table 8-22 indicates?

Hi Robert,

I did not see a response to some of my feedback but wanted to summarize
where I think the next version of this set needs to go:

1/ ACPI0017 is mandatory. If a BIOS does not provide ACPI0017 it is
explicitly opting the OS out of managing anything other than the CXL.io
side of memory expanders.

2/ Per table 8-22 in CXL 3.0 RCDs are not permitted to have HDM decoders
so that assumption in the driver needs to be reworked.

3/ It's not even clear that the Register Locator DVSEC has any role to
play in an RCD as every register the driver needs should be relative to
the RCRB. So the assumptions in the driver need to consider RCRB located
registers as a first class citizen.
