ioat3.2 does not support asynchronous error notifications which makes the driver experience latencies when non-zero pq validate results are expected. Provide a mechanism for turning off async_xor_val and async_syndrome_val via Kconfig. This approach is generally useful for any driver that specifies ASYNC_TX_DISABLE_CHANNEL_SWITCH and would like to force the async_tx api to fall back to the synchronous path for certain operations.

2009-11-16crypto: gcm - fix another complete call in complete fuctionHuang Ying1-34/+73
The flow of the complete function (xxx_done) in gcm.c is as follow: void complete(struct crypto_async_request *areq, int err) { struct aead_request *req = areq->data; if (!err) { err = async_next_step(); if (err == -EINPROGRESS || err == -EBUSY) return; } complete_for_next_step(areq, err); } But *areq may be destroyed in async_next_step(), this makes complete_for_next_step() can not work properly. To fix this, one of following methods is used for each complete function. - Add a __complete() for each complete(), which accept struct aead_request *req instead of areq, so avoid using areq after it is destroyed. - Expand complete_for_next_step(). The fixing method is based on the idea of Herbert Xu. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2009-10-19async_tx: fix asynchronous raid6 recovery for ddf layoutsDan Williams1-30/+56
The raid6 recovery code currently requires special handling of the 4-disk and 5-disk recovery scenarios for the native layout. Quoting from commit 0a82a623: In these situations the default N-disk algorithm will present 0-source or 1-source operations to dma devices. To cover for dma devices where the minimum source count is 2 we implement 4-disk and 5-disk handling in the recovery code. The ddf layout presents disks=6 and disks=7 to the recovery code in these situations. Instead of looking at the number of disks count the number of non-zero sources in the list and call the special case code when the number of non-failed sources is 0 or 1.

2009-10-19crypto: ghash - Add PCLMULQDQ accelerated implementationHuang Ying2-0/+15
PCLMULQDQ is used to accelerate the most time-consuming part of GHASH, carry-less multiplication. More information about PCLMULQDQ can be found at: http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode/ Because PCLMULQDQ changes XMM state, its usage must be enclosed with kernel_fpu_begin/end, which can be used only in process context, the acceleration is implemented as crypto_ahash. That is, request in soft IRQ context will be defered to the cryptd kernel thread. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-10-16raid6/async_tx: handle holes in block list in async_syndrome_valNeilBrown2-14/+35
async_syndrome_val check the P and Q blocks used for RAID6 calculations. With DDF raid6, some of the data blocks might be NULL, so this needs to be handled in the same way that async_gen_syndrome handles it. As async_syndrome_val calls async_xor, also enhance async_xor to detect and skip NULL blocks in the list. Signed-off-by: NeilBrown <neilb@suse.de>
2009-10-16md/async: don't pass a memory pointer as a page pointer.NeilBrown2-16/+15
md/raid6 passes a list of 'struct page *' to the async_tx routines, which then either DMA map them for offload, or take the page_address for CPU based calculations. For RAID6 we sometime leave 'blanks' in the list of pages. For CPU based calcs, we want to treat theses as a page of zeros. For offloaded calculations, we simply don't pass a page to the hardware. Currently the 'blanks' are encoded as a pointer to raid6_empty_zero_page. This is a 4096 byte memory region, not a 'struct page'. This is mostly handled correctly but is rather ugly. So change the code to pass and expect a NULL pointer for the blanks. When taking page_address of a page, we need to check for a NULL and in that case use raid6_empty_zero_page.

2009-09-08dmaengine, async_tx: add a "no channel switch" allocatorDan Williams1-0/+4
Channel switching is problematic for some dmaengine drivers as the architecture precludes separating the ->prep from ->submit. In these cases the driver can select ASYNC_TX_DISABLE_CHANNEL_SWITCH to modify the async_tx allocator to only return channels that support all of the required asynchronous operations. For example MD_RAID456=y selects support for asynchronous xor, xor validate, pq, pq validate, and memcpy. When ASYNC_TX_DISABLE_CHANNEL_SWITCH=y any channel with all these capabilities is marked DMA_ASYNC_TX allowing async_tx_find_channel() to quickly locate compatible channels with the guarantee that dependency chains will remain on one channel. When ASYNC_TX_DISABLE_CHANNEL_SWITCH=n async_tx_find_channel() may select channels that lead to operation chains that need to cross channel boundaries using the async_tx channel switch capability. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-09-08dmaengine: add fence supportDan Williams5-27/+50
Some engines optimize operation by reading ahead in the descriptor chain such that descriptor2 may start execution before descriptor1 completes. If descriptor2 depends on the result from descriptor1 then a fence is required (on descriptor2) to disable this optimization. The async_tx api could implicitly identify dependencies via the 'depend_tx' parameter, but that would constrain cases where the dependency chain only specifies a completion order rather than a data dependency. So, provide an ASYNC_TX_FENCE to explicitly identify data dependencies. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
