Subject: [PATCH 0/8] Add and implement gen_pool_dma_alloc()
Date: Fri, 1 Nov 2013 19:35:58 +0800 [thread overview]
Message-ID: <cover.1383303752.git.b42378@freescale.com> (raw)
Previously, we don't have a specific gen_pool_alloc() for DMA usage;
Instead, we need to use gen_pool_virt_to_phys() to convert the addr
returned from gen_pool_alloc(). So each implementation of this has
duplicated code. Thus add new helper function -- gen_pool_dma_alloc().
After gen_pool_dma_alloc() is introduced, we can replace the original
combination of gen_pool_alloc()+gen_pool_virt_to_phys() with this new
helper function. Thus this patch implement the helper function to all
the current drivers which use gen_pool_virt_to_phys().
!!-------------------important------------------!!
The later 7 patches need all related driver owner to test. We can
here define a simple rule:
1, If one driver owner or maintainer doesn't like the mofication
to his/her driver, just let me know. I would drop that patch.
2, If there's a bug and issue found after patch-testing, please
reply the mail so that I can fix and refine the patch.
3, If one driver owner or maintainer is too busy and doesn't have
bandwidth to test the patch, I would drop that patch from this
series. We can reimplement it till there's someone test it.
!!-------------------current progress-----------!!
