2013-07-11dpa_offload: Add protection against concurrent HM ops runtime modificationsMarian Chereji
When modifying a header manipulation operation at runtime, the DPA Classifier uses the FMD call FM_PCD_ManipNodeReplace. This function locks the entire PCD and will fail if the PCD is already locked (it is not a blocking function). The parallel access protection mechanism in DPA Classifier would only protect against parallel access ON THE SAME MANIP NODE. It used to ALLOW parallel access on DIFFERENT HM nodes, but this will fail due to the locking system in the FMD. This patch updates the locking mechanism in DPA Classifier for the HM runtime modification functions so that a single call to FM_PCD_ManipNodeReplace can happen at any one time.

The hibernation suspend flow is trapped from user space to kernel space, the PID register is user thread pid. The hibernation resume is begin in kernel start flow, the PID alway 0. After the kernel thread back to user thread, there is not have context switch and the pid can not update, because the kernel thread is trapped form user space. So if we did't restore PID the user space of thread will be addressing in the kernel space. There are two ways to restore PID: 1/ In swsusp_arch_suspend/swsusp_arch_resume, save/resotre PID register. 2/ Form restore_processor_state to restore. this function will do context switch. switch_mmu_context(current->active_mm, current->active_mm) PPC32 Using the second method.

2013-06-07dpaa_eth: Set a fixed upper limit for recycleable buffer sizeIoana Radulescu
Until now we considered a buffer recycleable if its size didn't exceed the buffer pool size by more than a certain amount. Recent changes in the stack however allow the allocation of skb buffers much larger than the requested size, which impacts our ability to recycle forwarded frames, especially when jumbo frame support is enabled. Make the recycling size upper limit a fixed and sufficiently large value, regardless of the default size of the buffer pool, in order to simplify recycling logic and guard against unfavourable cases.

2013-06-07dpaa_eth: Fix computation of cache paddingIoana Radulescu
When computing the padding between the beginning of a FD buffer and the head of the skb associated to it, we wrongly assume that this padding is always lower than PAGE_SIZE. In ip forward scenarios with jumbo frames support enabled and Rx extra headroom not zero, the above assumption is proven incorrect. Properly compute the padding size in order to avoid skb corruption.

2013-06-07crypto: caam - Implement QI driver context updateVakul Garg
On a crypto transform, a setkey() operation can be performed multiple times e.g. when keys are changed. These requires updation of shared descriptor in caam_qi driver. The shared descriptor in case of QI driver is maintained inside driver context and it is prefixed with pre-header. When shared descriptor is updated by the driver application, it needs to be copied again into driver context and pre-header should also be updated. With this patch, the caam_qi driver provides new api caam_drv_ctx_update(). The caam_qi driver application has been updated to call this api when setkey() operation changes shared descriptor.

fixed-link does not work in 3.8.x, to make XFI work which has no PHY, it's actually not necessary to use fixed-link, otherwise there will be more work and code changes to make fixed-link work in 3.8.x. For now, if driver does not find the phy_node of MAC, just set the mac_dev->phy_dev = NULL and return 0; we can get XFI work and this won't break other ethernet ports. It's only for SDK1.4, if we decide to bring fixed-link back, it can be done after SDK1.4.

2013-05-31dpaa_eth: Create TxConf FQs with HOLDACTIVE flagBogdan Hamciuc
Tx Confirmation FQs tend, with originating traffic, to generate a high number of portal interrupts. A machine doing only TCP transmits may well end up having more portal interrupts than its Rx peer. By setting the HOLDACTIVE flag on the Tx Confirmation FQs, we significantly reduce the number of portal interrupts in termination tests. The quantitative effect is anywhere between 2% and 4% on Tx-mainly cores (most visible in UDP_STREAM tests, least visible on TCP_STREAM).
