* | intel-iommu: optimize sg map/unmap callsKeshavamurthy, Anil S2007-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds PageSelectiveInvalidation support replacing existing DomainSelectiveInvalidation for intel_{map/unmap}_sg() calls and also enables to mapping one big contiguous DMA virtual address which is mapped to discontiguous physical address for SG map/unmap calls. "Doamin selective invalidations" wipes out the IOMMU address translation cache based on domain ID where as "Page selective invalidations" wipes out the IOMMU address translation cache for that address mask range which is more cache friendly when compared to Domain selective invalidations. Here is how it is done. 1) changes to iova.c alloc_iova() now takes a bool size_aligned argument, which when when set, returns the io virtual address that is naturally aligned to 2 ^ x, where x is the order of the size requested. Returning this io vitual address which is naturally aligned helps iommu to do the "page selective invalidations" which is IOMMU cache friendly over "domain selective invalidations". 2) Changes to driver/pci/intel-iommu.c Clean up intel_{map/unmap}_{single/sg} () calls so that s/g map/unamp calls is no more dependent on intel_{map/unmap}_single() intel_map_sg() now computes the total DMA virtual address required and allocates the size aligned total DMA virtual address and maps the discontiguous physical address to the allocated contiguous DMA virtual address. In the intel_unmap_sg() case since the DMA virtual address is contiguous and size_aligned, PageSelectiveInvalidation is used replacing earlier DomainSelectiveInvalidations.

* | Intel IOMMU: Avoid memory allocation failures in dma map api callsKeshavamurthy, Anil S2007-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel IOMMU driver needs memory during DMA map calls to setup its internal page tables and for other data structures. As we all know that these DMA map calls are mostly called in the interrupt context or with the spinlock held by the upper level drivers(network/storage drivers), so in order to avoid any memory allocation failure due to low memory issues, this patch makes memory allocation by temporarily setting PF_MEMALLOC flags for the current task before making memory allocation calls. We evaluated mempools as a backup when kmem_cache_alloc() fails and found that mempools are really not useful here because 1) We don't know for sure how much to reserve in advance 2) And mempools are not useful for GFP_ATOMIC case (as we call memory alloc functions with GFP_ATOMIC) (akpm: point 2 is wrong...) With PF_MEMALLOC flag set in the current->flags, the VM subsystem avoids any watermark checks before allocating memory thus guarantee'ing the memory till the last free page. Further, looking at the code in mm/page_alloc.c in __alloc_pages() function, looks like this flag is useful only in the non-interrupt context. If we are in the interrupt context and memory allocation in IOMMU driver fails for some reason, then the DMA map api's will return failure and it is up to the higher level drivers to retry. Suppose, if upper level driver programs the controller with the buggy DMA virtual address, the IOMMU will block that DMA transaction when that happens thus preventing any corruption to main memory. So far in our test scenario, we were unable to create any memory allocation failure inside dma map api calls.

As per Dave's suggestion we are now allocating IO virtual address from Higher DMA limit address rather than lower end address and this eliminated the need to preserve the IO virtual address for multiple devices sharing the same domain virtual address. Also this code uses red black trees to store the allocated and reserved iova nodes. This showed a good performance improvements over previous linear linked list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When devices are under a p2p bridge, upstream transactions get replaced by the device id of the bridge as it owns the PCIE transaction. Hence its necessary to setup translations on behalf of the bridge as well. Due to this limitation all devices under a p2p share the same domain in a DMAR. We just cache the type of device, if its a native PCIe device or not for later use.

(questions from akpm, answers from ak) > So... what's all this code for? > > I assume that the intent here is to speed things up under Xen, etc? Yes in some cases, but not this code. That would be the Xen version of this code that could potentially assign whole devices to guests. I expect this to be only useful in some special cases though because most hardware is not virtualizable and you typically want an own instance for each guest. Ok at some point KVM might implement this too; i likely would use this code for this. > Do we > have any benchmark results to help us to decide whether a merge would be > justified? The main advantage for doing it in the normal kernel is not performance, but more safety. Broken devices won't be able to corrupt memory by doing random DMA. Unfortunately that doesn't work for graphics yet, for that need user space interfaces for the X server are needed. There are some potential performance benefits too: - When you have a device that cannot address the complete address range an IOMMU can remap its memory instead of bounce buffering. Remapping is likely cheaper than copying. - The IOMMU can merge sg lists into a single virtual block. This could potentially speed up SG IO when the device is slow walking SG lists. [I long ago benchmarked 5% on some block benchmark with an old MPT Fusion; but it probably depends a lot on the HBA] And you get better driver debugging because unexpected memory accesses from the devices will cause a trappable event. > > Does it slow anything down? It adds more overhead to each IO so yes. This patch: Add support for early detection and parsing of DMAR's (DMA Remapping) reported to OS via ACPI tables. DMA remapping(DMAR) devices support enables independent address translations for Direct Memory Access(DMA) from Devices. These DMA remapping devices are reported via ACPI tables and includes pci device scope covered by these DMA remapping device.

|/ | | | | | | | | | | | | | | | | | | | | | Current memory notifier has some defects yet. (Fortunately, nothing uses it.) This patch is to fix and rearrange for them. - Add information of start_pfn, nr_pages, and node id if node status is changes from/to memoryless node for callback functions. Callbacks can't do anything without those information. - Add notification going-online status. It is necessary for creating per node structure before the node's pages are available. - Move GOING_OFFLINE status notification after page isolation. It is good place for return memory like cache for callback, because returned page is not used again. - Make CANCEL events for rollingback when error occurs. - Delete MEM_MAPPING_INVALID notification. It will be not used. - Fix compile error of (un)register_memory_notifier().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because rt2x00 implements the residual calculation different from what the legacy code does (i.e. scaled values), we need to adjust the residual check. Again, we are only mimicking the behaviour of the ralink driver without actually knowing what we do :-( Signed-off-by: Mattias Nissler <mattias.nissler@gmx.de> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
