stop using DMA_xxBIT_MASK

2007-10-18T21:37:21+00:00

Now that we have DMA_BIT_MASK(), these macros are pointless.

unify DMA_..BIT_MASK definitions: v3.1

2007-10-18T21:37:21+00:00

Remove redundant DMA_..BIT_MASK definitions across two drivers.  The
computation of the majority of the bitmasks is done by the compiler.  The
initial split of the patch touching each a different file got removed due
to possible git bisect breakage.

introduce DMA_MASK_NONE as a signal for unable to do DMA

2007-10-16T16:42:50+00:00

Some devices are incapable of DMA and need to be recognised as such.
Introduce a NONE dma mask to facilitate this plus an inline function:
is_device_dma_capable() to check this.

dma-mapping: prevent dma dependent code from linking on !HAS_DMA archs

2007-07-16T16:05:45+00:00

Continuing the work started in 411f0f3edc141a582190d3605cadd1d993abb6df ...

This enables code with a dma path, that compiles away, to build without
requiring additional code factoring.  It also prevents code that calls
dma_alloc_coherent and dma_free_coherent from linking whereas previously
the code would hit a BUG() at run time.  Finally, it allows archs that set
!HAS_DMA to delete their asm/dma-mapping.h file.

devres: device resource management

2007-02-09T22:39:36+00:00

Implement device resource management, in short, devres.  A device
driver can allocate arbirary size of devres data which is associated
with a release function.  On driver detach, release function is
invoked on the devres data, then, devres data is freed.

devreses are typed by associated release functions.  Some devreses are
better represented by single instance of the type while others need
multiple instances sharing the same release function.  Both usages are
supported.

devreses can be grouped using devres group such that a device driver
can easily release acquired resources halfway through initialization
or selectively release resources (e.g. resources for port 1 out of 4
ports).

This patch adds devres core including documentation and the following
managed interfaces.

* alloc/free	: devm_kzalloc(), devm_kzfree()
* IO region	: devm_request_region(), devm_release_region()
* IRQ		: devm_request_irq(), devm_free_irq()
* DMA		: dmam_alloc_coherent(), dmam_free_coherent(),
		  dmam_declare_coherent_memory(), dmam_pool_create(),
		  dmam_pool_destroy()
* PCI		: pcim_enable_device(), pcim_pin_device(), pci_is_managed()
* iomap		: devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(),
		  devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(),
		  pcim_iomap(), pcim_iounmap()

[PATCH] Move valid_dma_direction() from x86_64 to generic code

2006-09-29T16:18:10+00:00

As suggested by Muli Ben-Yehuda this function is moved to generic code as
may be useful for all archs.
