[Nouveau] [RFC v3 00/45] dma-mapping: Use unsigned long for dma_attrs
Hi,
This is third approach (complete this time) for replacing struct
dma_attrs with unsigned long.
The main patch (2/45) doing the change is split into many subpatches
for easier review (3-43). They should be squashed together when
applying.
*Important:* Patchset is *only* build tested on allyesconfigs: ARM,
ARM64, i386, x86_64 and powerpc. Please provide reviewes and tests
for other platforms.
Rebased on next-20160602.
For easier testing the patchset is available here:
repo: https://github.com/krzk/linux
branch: for-next/dma-attrs-const-v3
I didn't CC all the maintainers... the list is too big.
Changes since v2
===============1. Follow Christoph Hellwig's comments (don't use BIT add
documentation, remove dma_get_attr).
Rationale
========The dma-mapping core and the implementations do not change the
DMA attributes passed by pointer. Thus the pointer can point to const
data. However the attributes do not have to be a bitfield. Instead
unsigned long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.
Best regards,
Krzysztof
