I thought these devices to be on the platform bus as the device is of type
'struct platform_device', though I am not sure then why 'of_dma_configure()'
is called here. Is this not on platform bus?

I see this API being called indirectly from NXP DPAA device driver which
is for platform bus devices. So I marked 'true' out here. There are more places
from where it is being called.

The conditional here is somewhat pointless since the of_node should
always be set. If it weren't it should be considered a bug and this
function welcome to crash to make that very obvious.

The conditional here is somewhat pointless since the of_node should
always be set. If it weren't it should be considered a bug and this
function welcome to crash to make that very obvious.

Either way:

[v4,2/2] drivers: remove force dma flag from buses

[Nipun Gupta]

With each bus implementing its own DMA configuration callback,
there is no need for bus to explicitly have force_dma in its
global structure. This patch modifies of_dma_configure API to
accept an input parameter which specifies if implicit DMA
configuration is required even when it is not described by the
firmware.

there is no need for bus to explicitly have force_dma in its
global structure. This patch modifies of_dma_configure API to
accept an input parameter which specifies if implicit DMA
configuration is required even when it is not described by the
firmware.

[v4,1/2] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

It is bus specific aspect to map a given device on the bus and
relevant firmware description of its DMA configuration.
So, this change introduces 'dma_configure' as bus callback
giving flexibility to busses for implementing its own dma
configuration function.

The change eases the addition of new busses w.r.t. adding the dma
configuration functionality.

This patch also updates the PCI, Platform, ACPI and host1x bus to
use new introduced callbacks.

 - The patches are based on the comments on:
   https://patchwork.kernel.org/patch/10259087/

Changes in v2:
  - Do not have dma_deconfigure callback
  - Have '/dma_common_configure/' API to provide a common DMA
    configuration which can be used by busses if it suits them.
  - Platform and ACPI bus to use '/dma_common_configure/' in
    '/dma_configure/' callback.
  - Updated commit message
  - Updated pci_dma_configure API with changes suggested by Robin

Changes in v3:
  - Move dma_common_configure() within platform_dma_configure() and
    reuse platofrm_dma_configure() for AMBA bus too
  - Declare 'attr' in pci_dma_configure() inside the else statement
    where it is used.

Changes in v4:
  - Rebased on top of 4.17-rc2

[PATCH v4 1/2] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

It is bus specific aspect to map a given device on the bus and
relevant firmware description of its DMA configuration.
So, this change introduces 'dma_configure' as bus callback
giving flexibility to busses for implementing its own dma
configuration function.

The change eases the addition of new busses w.r.t. adding the dma
configuration functionality.

This patch also updates the PCI, Platform, ACPI and host1x bus to
use new introduced callbacks.

Suggested-by: Christoph Hellwig <hch@lst.de>
Signed-off-by: Nipun Gupta <nipun.gupta@nxp.com>
Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Acked-by: Bjorn Helgaas <bhelgaas@google.com>  # PCI parts
---
 - The patches are based on the comments on:
   https://patchwork.kernel.org/patch/10259087/

Changes in v2:
  - Do not have dma_deconfigure callback
  - Have '/dma_common_configure/' API to provide a common DMA
    configuration which can be used by busses if it suits them.
  - Platform and ACPI bus to use '/dma_common_configure/' in
    '/dma_configure/' callback.
  - Updated commit message
  - Updated pci_dma_configure API with changes suggested by Robin

Changes in v3:
  - Move dma_common_configure() within platform_dma_configure() and
    reuse platofrm_dma_configure() for AMBA bus too
  - Declare 'attr' in pci_dma_configure() inside the else statement
    where it is used.

Changes in v4:
  - Rebased on top of 4.17-rc2

[PATCH v3 2/2] drivers: remove force dma flag from buses

[Nipun Gupta]

With each bus implementing its own DMA configuration callback,
there is no need for bus to explicitly have force_dma in its
global structure. This patch modifies of_dma_configure API to
accept an input parameter which specifies if implicit DMA
configuration is required even when it is not described by the
firmware.

[v3,1/2] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

It is bus specific aspect to map a given device on the bus and
relevant firmware description of its DMA configuration.
So, this change introduces 'dma_configure' as bus callback
giving flexibility to busses for implementing its own dma
configuration function.

The change eases the addition of new busses w.r.t. adding the dma
configuration functionality.

This patch also updates the PCI, Platform, ACPI and host1x bus to
use new introduced callbacks.

 - The patches are based on the comments on:
   https://patchwork.kernel.org/patch/10259087/

Changes in v2:
  - Do not have dma_deconfigure callback
  - Have '/dma_common_configure/' API to provide a common DMA
    configuration which can be used by busses if it suits them.
  - Platform and ACPI bus to use '/dma_common_configure/' in
    '/dma_configure/' callback.
  - Updated commit message
  - Updated pci_dma_configure API with changes suggested by Robin

Changes in v3
  - Move dma_common_configure() within platform_dma_configure() and
    reuse platofrm_dma_configure() for AMBA bus too
  - Declare 'attr' in pci_dma_configure() inside the else statement
    where it is used.

[PATCH v3 1/2] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

It is bus specific aspect to map a given device on the bus and
relevant firmware description of its DMA configuration.
So, this change introduces 'dma_configure' as bus callback
giving flexibility to busses for implementing its own dma
configuration function.

The change eases the addition of new busses w.r.t. adding the dma
configuration functionality.

This patch also updates the PCI, Platform, ACPI and host1x bus to
use new introduced callbacks.

 - The patches are based on the comments on:
   https://patchwork.kernel.org/patch/10259087/

Changes in v2:
  - Do not have dma_deconfigure callback
  - Have '/dma_common_configure/' API to provide a common DMA
    configuration which can be used by busses if it suits them.
  - Platform and ACPI bus to use '/dma_common_configure/' in
    '/dma_configure/' callback.
  - Updated commit message
  - Updated pci_dma_configure API with changes suggested by Robin

Changes in v3
  - Move dma_common_configure() within platform_dma_configure() and
    reuse platofrm_dma_configure() for AMBA bus too
  - Declare 'attr' in pci_dma_configure() inside the else statement
    where it is used.

okay, that would be fine, trivial query - will it be okay to include
'linux/platform_device.h' in the AMBA bus? I am reluctant for this change
because of including platform file.

Thanks,

Then we'd still have a dependency of common code on OF and ACPI.

On the other hand we'd get free OF and ACPI dma ranges parsing for
everyone, which might be handy.  And which would really help mitigating
the risk that we missed some bus that gets dma configuration from OF,
so maybe it actually is a good idea.  I'd just rename it to
dma_default_configure or similar in that case.

So it turns out we only end with two callers of dma_common_configure
after this series.  Based ont hat I'm tempted with the suggestion
from Robin to just have amba call platform_dma_configure, and move
the code from dma_common_configure to platform_dma_configure.

As grep pointed out this wants a blank line after the function, and while
in nitpicking mode I'd suggest to remove the blank line above the return
statement while at it.

How about we do not pass any flag in 'dma_common_configure()', and inside this
API we pass "true" to 'of_dma_configure()'? I am saying this because currently
both the busses (platform and AMBA) which uses 'dma_common_configure()' passes
"true" value. If we create additional 'dma_common_configure_force()', then
'dma_common_configure()' will not be used anytime and will become redundant.

If someday new busses come and they needs to use similar functionality which
'dma_common_configure()' provides, but with passing "false" to 'of_dma_configure()',
then what you suggests of having two separate such API's will be more reasonable
and can be implemented?

How about we do not pass any flag in 'dma_common_configure()', and inside this

both the busses (platform and AMBA) which uses 'dma_common_configure()' passes

[v2,2/2] drivers: remove force dma flag from buses

Having to "remember" what that bool variable means on the end of the
function call is a royal pain over time, right?

Why not just create a new function:
	dma_common_configure_force(dma)
that always does this?  Leave "dma_common_configure()" alone, and then
wrap the old code with these two helper functions that call the 'core'
code with the bool set properly?

That way you do not have to "know" what that parameter is, the function
name just documents it automatically, so when you see it in the
bus-specific code, no need to go and have to hunt for anything.  And if
you are reading the dma core code, it's obvious what is happening as the
functions are all right there.

thanks,

Blank line after the new function declaration?

Other than those very minor things, nice job, this looks good:

[v2,2/2] drivers: remove force dma flag from buses

there is no need for bus to explicitly have force_dma in its

accept an input parameter which specifies if implicit DMA
configuration is required even when it is not described by the

[PATCH v2 2/2] drivers: remove force dma flag from buses

[Nipun Gupta]

With each bus implementing its own DMA configuration callback,
there is no need for bus to explicitly have force_dma in its
global structure. This patch modifies of_dma_configure API to
accept an input parameter which specifies if implicit DMA
configuration is required even when it is not described by the
firmware.

[v2,1/2] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

It's bus specific aspect to map a given device on the bus and
relevant firmware description of its DMA configuration.
So, this change introduces '/dma_configure/' as bus callback
giving flexibility to busses for implementing its own dma
configuration function.

The change eases the addition of new busses w.r.t. adding the dma
configuration functionality.

This patch also updates the PCI, Platform, ACPI and host1x bus to
use new introduced callbacks.

Suggested-by: Christoph Hellwig <hch@lst.de>
Signed-off-by: Nipun Gupta <nipun.gupta@nxp.com>
---
 - The patches are based on the comments on:
   https://patchwork.kernel.org/patch/10259087/

Changes in v2:
  - Do not have dma_deconfigure callback
  - Have '/dma_common_configure/' API to provide a common DMA
    configuration which can be used by busses if it suits them.
  - Platform and ACPI bus to use '/dma_common_configure/' in
    '/dma_configure/' callback.
  - Updated commit message
  - Updated pci_dma_configure API with changes suggested by Robin

[PATCH v2 1/2] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

It's bus specific aspect to map a given device on the bus and
relevant firmware description of its DMA configuration.
So, this change introduces '/dma_configure/' as bus callback
giving flexibility to busses for implementing its own dma
configuration function.

The change eases the addition of new busses w.r.t. adding the dma
configuration functionality.

This patch also updates the PCI, Platform, ACPI and host1x bus to
use new introduced callbacks.

 - The patches are based on the comments on:
   https://patchwork.kernel.org/patch/10259087/

Changes in v2:
  - Do not have dma_deconfigure callback
  - Have '/dma_common_configure/' API to provide a common DMA
    configuration which can be used by busses if it suits them.
  - Platform and ACPI bus to use '/dma_common_configure/' in
    '/dma_configure/' callback.
  - Updated commit message
  - Updated pci_dma_configure API with changes suggested by Robin

[PATCH] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

The change introduces 'dma_configure' & 'dma_deconfigure'as
bus callback functions so each bus can choose to implement
its own dma configuration function.
This eases the addition of new busses w.r.t. adding the dma
configuration functionality.

The change also updates the PCI, Platform and ACPI bus to use
new introduced callbacks.

 - This patch is based on the comments on:
   https://patchwork.kernel.org/patch/10259087/
 - I have validated for PCI and platform, but not for AMBA as I
   do not have infrastructure to validate it.
   Can anyone please validate them on AMBA?

Isn't this one or the other one but not both?

Something like:

if (dev->of_node)
	of_dma_deconfigure(dev);
else
	acpi_dma_deconfigure(dev);

should work.

I understand your point. Seems reasonable as we should not expect
the 'of/acpi DMA deconfigure' API to not fail when they are not configured.

But, here we would also need to get dma_device (just as we get in
'pci_dma_configure') and need a check on it as for PCI there 'of_node'
is present in the dma_dev.

Ill update this in v2, and also make similar changes for platform and AMBA bus.

Thanks,

Both of_dma_deconfigure and acpi_dma_deconfigure just end up calling
arch_teardown_dma_ops.  So my preference would be to just remove
of_dma_deconfigure and acpi_dma_deconfigure and call arch_teardown_dma_ops
as a prep patch before this one.

This code sniplet is duplicated so many times that I think we should
just have some sort of dma_common_configure() for it that the various
busses can use.

As mention in my previous reply I think we don't even need a deconfigure
callback at this point - just remove the ACPI and OF wrappers and
clear the dma ops.

Also in this series we should replace the force_dma flag by use of the
proper method, e.g. give a force parameter to of_dma_configure and the
new dma_common_configure helper that the busses that want it can set.

Agree. There is no good point in duplicating the code.
So this new API will be part of 'drivers/base/dma-mapping.c' file?

I am more inclined to what Robin states in other mail to keep symmetry.
i.e. to keep dma_configure() and dma_deconfigure() and call
dev->bus->dma_configure from dma_configure(). Is this okay?

It's probably worth clarifying - either in the commit message, the 
kerneldoc, or both - that the bus-specific aspect is that of mapping 
between a given device on the bus and the relevant firmware description 
of its DMA configuration.

I would be inclined to have amba_bustype just reference 
platform_dma_configure() directly rather than duplicate it like this, 
since there's no sensible reason for them to ever differ.

This patch should also be removing force_dma because it no longer makes 
sense. If DMA configuration is now done by a bus-level callback, then a 
bus which wants its children to get DMA configuration needs to implement 
that callback; there's nowhere to force a "default" global behaviour any 
more.

You don't need dma_dev here; see the code removed in 09515ef5ddad for

Seeing it laid out in the patch, I really don't think we need a 
deconfigure callback like this - the fact that we're just copy-pasting 
the existing implementation everywhere is a big hint, but more 
conceptually I can't see a good reason for it to ever need bus-specific 
behaviour in the same way that configure does.

Maybe that means we keep dma_configure() around for the sake of 
symmetry, but just reduce it to:

int dma_configure(struct device *dev)
{
	if (dev->bus->dma_configure)
		return dev->bus->dma_configure(dev);
	return 0;
}

Realistically though, dma_deconfigure() only exists for the sake of 
calling arch_teardown_dma_ops(), and that only really exists for the 
sake of the old ARM IOMMU code, so I'm not inclined to pretend it's 
anywhere near as important as the dma_configure() path in design terms.

It's probably worth clarifying - either in the commit message, the 
kerneldoc, or both - that the bus-specific aspect is that of mapping 
between a given device on the bus and the relevant firmware description 
of its DMA configuration.

I would be inclined to have amba_bustype just reference 
platform_dma_configure() directly rather than duplicate it like this, 
since there's no sensible reason for them to ever differ.

This patch should also be removing force_dma because it no longer makes 
sense. If DMA configuration is now done by a bus-level callback, then a 
bus which wants its children to get DMA configuration needs to implement 
that callback; there's nowhere to force a "default" global behaviour any 
more.

You don't need dma_dev here; see the code removed in 09515ef5ddad for 
how the logic originally worked.

I think dma_common_configure() having this as the common code seems pretty
Decent. All the busses will probably call this API.

Agree. We will also need to pass a force_dma flag in of_dma_configure() as
Christoph suggests. Ill update this.

Yes, I will remove dma_deconfigure callback.

I think dma_common_configure() having this as the common code seems pretty
Decent. All the busses will probably call this API.

Agree. We will also need to pass a force_dma flag in of_dma_configure() as
Christoph suggests. Ill update this.

Re: [PATCH] dma-mapping: move dma configuration to bus infrastructure

[Christoph Hellwig]

Can you resend the current state of affairs so we can get it in for
4.17?

RE: [PATCH] dma-mapping: move dma configuration to bus infrastructure

[Nipun Gupta]

I am just going to send it within an hour :)

Changes to the driver core and 3 different busses 2 days before 4.16 is

test on my end, sorry.
