[PATCH/RFC 0/6] Allow compile-testing NO_DMA

[PATCH/RFC 0/6] Allow compile-testing NO_DMA

[Geert Uytterhoeven]

	Hi all,

If NO_DMA=y, get_dma_ops() returns a reference to the non-existing
symbol bad_dma_ops, thus causing a link failure if it is ever used.

The intention of this is twofold:
  1. To catch users of the DMA API on systems that do no support the DMA
     mapping API,
  2. To avoid building drivers that cannot work on such systems anyway.

However, the disadvantage is that we have to keep on adding dependencies
on HAS_DMA all over the place.

Thanks to the COMPILE_TEST symbol, lots of drivers now depend on one or
more platform dependencies (that imply HAS_DMA) || COMPILE_TEST, thus
already covering intention #2.  Having to add an explicit dependency on
HAS_DMA here is cumbersome, and hinders compile-testing.

Hence I think the time is ripe to reconsider the link failure.
This patch series:
  - Changes get_dma_ops() to return NULL instead,
  - Adds a few more dummies to enable compile-testing,
  - Removes dependencies on HAS_DMA for symbols that already have
    platform dependencies implying HAS_DMA.

Note that adding more platform dependencies and/or dependencies on
COMPILE_TEST is encouraged!

This may make life harder for UML, though, as UML usually satisfies all
other platform dependencies for HAS_DMA.  Similarly, HAS_IOMEM is even
more complicated.  Can/do we want to do something similar for
HAS_IOMEM?

This series is against my current local tree, which has a few more
"depends on HAS_DMA" than upstream.  Of course I will rebase, and split
the last patch per subsystem, if this RFC is welcomed positively.

Compile-tested with allmodconfig and allyesconfig for m68k/sun3.

Thanks for your comments!

[PATCH/RFC 3/6] usb: gadget: Add NO_DMA dummies for DMA mapping API

[Geert Uytterhoeven]

Add dummies for usb_gadget_{,un}map_request{,_by_dev}(), to allow
compile-testing if NO_DMA=y.

This prevents the following from showing up later:

[PATCH/RFC 6/6] Treewide: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Notes:
  - FSL_FMAN keeps its dependency on HAS_DMA, as it calls set_dma_ops(),
    which does not exist if HAS_DMA=n (Do we need a dummy? The use of
    set_dma_ops() in this driver is questionable),
  - SND_SOC_LPASS_IPQ806X and SND_SOC_LPASS_PLATFORM loose their
    dependency on HAS_DMA, as they are selected from
    SND_SOC_APQ8016_SBC.

[PATCH/RFC,6/6] Treewide: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Notes:
  - FSL_FMAN keeps its dependency on HAS_DMA, as it calls set_dma_ops(),
    which does not exist if HAS_DMA=n (Do we need a dummy? The use of
    set_dma_ops() in this driver is questionable),
  - SND_SOC_LPASS_IPQ806X and SND_SOC_LPASS_PLATFORM loose their
    dependency on HAS_DMA, as they are selected from
    SND_SOC_APQ8016_SBC.

[PATCH/RFC 6/6] Treewide: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Notes:
  - FSL_FMAN keeps its dependency on HAS_DMA, as it calls set_dma_ops(),
    which does not exist if HAS_DMA=n (Do we need a dummy? The use of
    set_dma_ops() in this driver is questionable),
  - SND_SOC_LPASS_IPQ806X and SND_SOC_LPASS_PLATFORM loose their
    dependency on HAS_DMA, as they are selected from
    SND_SOC_APQ8016_SBC.

Nit: It might be tidier to add *all* the stubs down here so that there 
only need be a single #ifdef, then move the dma_pool_zalloc definition 
outside at the end (where we might eventually get rid of it anyway).

Other than that, though, I think I agree with the series in general - 
more COMPILE_TEST is always good from the point of view of weeding out 
drivers using architecture-specific DMA API internals which aren't part 
of the proper generic interface.

It looks like we have only one real arch (score) without IOMEM, and two 
(s390 and tile) where it is possible to configure out, so it does seem 
like a reasonable feature to assume. Maybe we could have something like 
asm-generic/no-io.h to provide an "unimplemented" version of those 
interfaces.

Anyway, for this series:

David Woodhouse has been looking at some other structures with indirect
pointers (kvm_x86_ops) to reduce the overhead that was added for
avoiding speculative execution of those pointers. I wonder if there are
any dma_map_ops operations that are in a fastpath that needs a similar
optimization. If yes, we might want to think about how to do that part
first to avoid rewriting the same code more than once.

Otherwise, your approach seems fine.

David Woodhouse has been looking at some other structures with indirect
pointers (kvm_x86_ops) to reduce the overhead that was added for
avoiding speculative execution of those pointers. I wonder if there are
any dma_map_ops operations that are in a fastpath that needs a similar
optimization. If yes, we might want to think about how to do that part
first to avoid rewriting the same code more than once.

Otherwise, your approach seems fine.

Agreed, there is no use trying to optimize for any of those three cases:

For s390, all new machines come with PCI, so distros will enable it all
the time. Few users run their own kernels even on older machines.

score has been de-facto unmaintained for a few years, and tile has
recently been orphaned with the hardware platform being abandoned by
Mellanox.
