git://git.infradead.org/users/dwmw2/byteswap Pull preparatory gcc intrisics bswap patch from David Woodhouse: "This single patch is effectively a no-op for now. It enables architectures to opt in to using GCC's __builtin_bswapXX() intrinsics for byteswapping, and if we merge this now then the architecture maintainers can enable it for their arch during the next cycle without dependency issues. It's worth making it a par-arch opt-in, because although in *theory* the compiler should never do worse than hand-coded assembler (and of course it also ought to do a lot better on platforms like Atom and PowerPC which have load-and-swap or store-and-swap instructions), that isn't always the case.

2012-12-17ptrace: introduce PTRACE_O_EXITKILLOleg Nesterov1-1/+4
Ptrace jailers want to be sure that the tracee can never escape from the control. However if the tracer dies unexpectedly the tracee continues to run in potentially unsafe mode. Add the new ptrace option PTRACE_O_EXITKILL. If the tracer exits it sends SIGKILL to every tracee which has this bit set. Note that the new option is not equal to the last-option << 1. Because currently all options have an event, and the new one starts the eventless group. It uses the random 20 bit, so we have the room for 12 more events, but we can also add the new eventless options below this one. Suggested by Amnon Shiloh.

2012-12-17drm/i915: Implement workaround for broken CS tlb on i830/845Daniel Vetter1-0/+10
Now that Chris Wilson demonstrated that the key for stability on early gen 2 is to simple _never_ exchange the physical backing storage of batch buffers I've tried a stab at a kernel solution. Doesn't look too nefarious imho, now that I don't try to be too clever for my own good any more. v2: After discussing the various techniques, we've decided to always blit batches on the suspect devices, but allow userspace to opt out of the kernel workaround assume full responsibility for providing coherent batches. The principal reason is that avoiding the blit does improve performance in a few key microbenchmarks and also in cairo-trace replays.

2012-12-16Merge tag 'balancenuma-v11' of ↵Linus Torvalds1-3/+12
git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma Pull Automatic NUMA Balancing bare-bones from Mel Gorman: "There are three implementations for NUMA balancing, this tree (balancenuma), numacore which has been developed in tip/master and autonuma which is in aa.git. In almost all respects balancenuma is the dumbest of the three because its main impact is on the VM side with no attempt to be smart about scheduling. In the interest of getting the ball rolling, it would be desirable to see this much merged for 3.8 with the view to building scheduler smarts on top and adapting the VM where required for 3.9. The most recent set of comparisons available from different people are mel: https://lkml.org/lkml/2012/12/9/108 mingo: https://lkml.org/lkml/2012/12/7/331 tglx: https://lkml.org/lkml/2012/12/10/437 srikar: https://lkml.org/lkml/2012/12/10/397 The results are a mixed bag. In my own tests, balancenuma does reasonably well. It's dumb as rocks and does not regress against mainline. On the other hand, Ingo's tests shows that balancenuma is incapable of converging for this workloads driven by perf which is bad but is potentially explained by the lack of scheduler smarts. Thomas' results show balancenuma improves on mainline but falls far short of numacore or autonuma. Srikar's results indicate we all suffer on a large machine with imbalanced node sizes. My own testing showed that recent numacore results have improved dramatically, particularly in the last week but not universally. We've butted heads heavily on system CPU usage and high levels of migration even when it shows that overall performance is better. There are also cases where it regresses. Of interest is that for specjbb in some configurations it will regress for lower numbers of warehouses and show gains for higher numbers which is not reported by the tool by default and sometimes missed in treports. Recently I reported for numacore that the JVM was crashing with NullPointerExceptions but currently it's unclear what the source of this problem is. Initially I thought it was in how numacore batch handles PTEs but I'm no longer think this is the case. It's possible numacore is just able to trigger it due to higher rates of migration. These reports were quite late in the cycle so I/we would like to start with this tree as it contains much of the code we can agree on and has not changed significantly over the last 2-3 weeks." * tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma: (50 commits) mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable mm/rmap: Convert the struct anon_vma::mutex to an rwsem mm: migrate: Account a transhuge page properly when rate limiting mm: numa: Account for failed allocations and isolations as migration failures mm: numa: Add THP migration for the NUMA working set scanning fault case build fix mm: numa: Add THP migration for the NUMA working set scanning fault case. mm: sched: numa: Delay PTE scanning until a task is scheduled on a new node mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG mm: sched: numa: Control enabling and disabling of NUMA balancing mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate mm: numa: Use a two-stage filter to restrict pages being migrated for unlikely task<->node relationships mm: numa: migrate: Set last_nid on newly allocated page mm: numa: split_huge_page: Transfer last_nid on tail page mm: numa: Introduce last_nid to the page frame sched: numa: Slowly increase the scanning period as NUMA faults are handled mm: numa: Rate limit setting of pte_numa if node is saturated mm: numa: Rate limit the amount of memory that is migrated between nodes mm: numa: Structures for Migrate On Fault per NUMA migration rate limiting mm: numa: Migrate pages handled during a pmd_numa hinting fault mm: numa: Migrate on reference policy ...

2012-12-15drm/exynos: add ipp subsystemEunchul Kim1-0/+190
This patch adds Image Post Processing(IPP) support for exynos drm driver. IPP supports image scaler/rotator and input/output DMA operations using IPP subsystem framework to control FIMC, Rotator and GSC hardware and supports some user interfaces for user side. And each IPP-based drivers support Memory to Memory operations with various converting. And in case of FIMC hardware, it also supports Writeback and Display output operations through local path. Features: - Memory to Memory operation support. - Various pixel formats support. - Image scaling support. - Color Space Conversion support. - Image crop operation support. - Rotate operation support to 90, 180 or 270 degree. - Flip operation support to vertical, horizontal or both. - Writeback operation support to display blended image of FIMD fifo on screen A summary to IPP Subsystem operations: First of all, user should get property capabilities from IPP subsystem and set these properties to hardware registers for desired operations. The properties could be pixel format, position, rotation degree and flip operation. And next, user should set source and destination buffer data using DRM_EXYNOS_IPP_QUEUE_BUF ioctl command with gem handles to source and destinition buffers. And next, user can control user-desired hardware with desired operations such as play, stop, pause and resume controls. And finally, user can aware of dma operation completion and also get destination buffer that it contains user-desried result through dequeue command. IOCTL commands: - DRM_EXYNOS_IPP_GET_PROPERTY . get ipp driver capabilitis and id. - DRM_EXYNOS_IPP_SET_PROPERTY . set format, position, rotation, flip to source and destination buffers - DRM_EXYNOS_IPP_QUEUE_BUF . enqueue/dequeue buffer and make event list. - DRM_EXYNOS_IPP_CMD_CTRL . play/stop/pause/resume control. Event: - DRM_EXYNOS_IPP_EVENT . a event to notify dma operation completion to user side. Basic control flow: Open -> Get properties -> User choose desired IPP sub driver(FIMC, Rotator or GSCALER) -> Set Property -> Create gem handle -> Enqueue to source and destination buffers -> Command control(Play) -> Event is notified to User -> User gets destinition buffer complated -> (Enqueue to source and destination buffers -> Event is notified to User) * N -> Queue/Dequeue to source and destination buffers -> Command control(Stop) -> Free gem handle -> Close Changelog v1 ~ v5: - added comments, code fixups and cleanups.

2012-12-11mm: support more pagesizes for MAP_HUGETLB/SHM_HUGETLBAndi Kleen2-0/+13
There was some desire in large applications using MAP_HUGETLB or SHM_HUGETLB to use 1GB huge pages on some mappings, and stay with 2MB on others. This is useful together with NUMA policy: use 2MB interleaving on some mappings, but 1GB on local mappings. This patch extends the IPC/SHM syscall interfaces slightly to allow specifying the page size. It borrows some upper bits in the existing flag arguments and allows encoding the log of the desired page size in addition to the *_HUGETLB flag. When 0 is specified the default size is used, this makes the change fully compatible. Extending the internal hugetlb code to handle this is straight forward. Instead of a single mount it just keeps an array of them and selects the right mount based on the specified page size. When no page size is specified it uses the mount of the default page size. The change is not visible in /proc/mounts because internal mounts don't appear there. It also has very little overhead: the additional mounts just consume a super block, but not more memory when not used. I also exported the new flags to the user headers (they were previously under __KERNEL__). Right now only symbols for x86 and some other architecture for 1GB and 2MB are defined. The interface should already work for all other architectures though. Only architectures that define multiple hugetlb sizes actually need it (that is currently x86, tile, powerpc). However tile and powerpc have user configurable hugetlb sizes, so it's not easy to add defines. A program on those architectures would need to query sysfs and use the appropiate log2.

The use of MPOL_NOOP and MPOL_MF_LAZY to allow an application to explicitly request lazy migration is a good idea but the actual API has not been well reviewed and once released we have to support it. For now this patch prevents an application using the services. This will need to be revisited. Signed-off-by: Mel Gorman <[email protected]>
2012-12-11mm: mempolicy: Add MPOL_MF_LAZYLee Schermerhorn1-3/+10
NOTE: Once again there is a lot of patch stealing and the end result is sufficiently different that I had to drop the signed-offs. Will re-add if the original authors are ok with that. This patch adds another mbind() flag to request "lazy migration". The flag, MPOL_MF_LAZY, modifies MPOL_MF_MOVE* such that the selected pages are marked PROT_NONE. The pages will be migrated in the fault path on "first touch", if the policy dictates at that time. "Lazy Migration" will allow testing of migrate-on-fault via mbind(). Also allows applications to specify that only subsequently touched pages be migrated to obey new policy, instead of all pages in range. This can be useful for multi-threaded applications working on a large shared data area that is initialized by an initial thread resulting in all pages on one [or a few, if overflowed] nodes. After PROT_NONE, the pages in regions assigned to the worker threads will be automatically migrated local to the threads on 1st touch.

2012-12-11mm: mempolicy: Check for misplaced pageLee Schermerhorn1-0/+1
This patch provides a new function to test whether a page resides on a node that is appropriate for the mempolicy for the vma and address where the page is supposed to be mapped. This involves looking up the node where the page belongs. So, the function returns that node so that it may be used to allocated the page without consulting the policy again. A subsequent patch will call this function from the fault path. Because of this, I don't want to go ahead and allocate the page, e.g., via alloc_page_vma() only to have to free it if it has the correct policy. So, I just mimic the alloc_page_vma() node computation logic--sort of. Note: we could use this function to implement a MPOL_MF_STRICT behavior when migrating pages to match mbind() mempolicy--e.g., to ensure that pages in an interleaved range are reinterleaved rather than left where they are when they reside on any page in the interleave nodemask.

2012-12-11mm: mempolicy: Add MPOL_NOOPLee Schermerhorn1-0/+1
This patch augments the MPOL_MF_LAZY feature by adding a "NOOP" policy to mbind(). When the NOOP policy is used with the 'MOVE and 'LAZY flags, mbind() will map the pages PROT_NONE so that they will be migrated on the next touch. This allows an application to prepare for a new phase of operation where different regions of shared storage will be assigned to worker threads, w/o changing policy. Note that we could just use "default" policy in this case. However, this also allows an application to request that pages be migrated, only if necessary, to follow any arbitrary policy that might currently apply to a range of pages, without knowing the policy, or without specifying multiple mbind()s for ranges with different policies.

This patch adds the multiqueue (VIRTIO_NET_F_MQ) support to virtio_net driver. VIRTIO_NET_F_MQ capable device could allow the driver to do packet transmission and reception through multiple queue pairs and does the packet steering to get better performance. By default, one one queue pair is used, user could change the number of queue pairs by ethtool in the next patch. When multiple queue pairs is used and the number of queue pairs is equal to the number of vcpus. Driver does the following optimizations to implement per-cpu virt queue pairs: - select the txq based on the smp processor id. - smp affinity hint to the cpu that owns the queue pairs. This could be used with the flow steering support of the device to guarantee the packets of a single flow is handled by the same cpu.

2012-12-06byteorder: allow arch to opt to use GCC intrinsics for byteswappingDavid Woodhouse1-3/+9
Since GCC 4.4, there have been __builtin_bswap32() and __builtin_bswap16() intrinsics. A __builtin_bswap16() came a little later (4.6 for PowerPC, 48 for other platforms). By using these instead of the inline assembler that most architectures have in their __arch_swabXX() macros, we let the compiler see what's actually happening. The resulting code should be at least as good, and much *better* in the cases where it can be combined with a nearby load or store, using a load-and-byteswap or store-and-byteswap instruction (e.g. lwbrx/stwbrx on PowerPC, movbe on Atom). When GCC is sufficiently recent *and* the architecture opts in to using the intrinsics by setting CONFIG_ARCH_USE_BUILTIN_BSWAP, they will be used in preference to the __arch_swabXX() macros. An architecture which does not set ARCH_USE_BUILTIN_BSWAP will continue to use its own hand-crafted macros. Signed-off-by: David Woodhouse <[email protected]> Acked-by: H.

2012-12-06KVM: PPC: Book3S HV: Provide a method for userspace to read and write the HPTPaul Mackerras1-0/+3
A new ioctl, KVM_PPC_GET_HTAB_FD, returns a file descriptor. Reads on this fd return the contents of the HPT (hashed page table), writes create and/or remove entries in the HPT. There is a new capability, KVM_CAP_PPC_HTAB_FD, to indicate the presence of the ioctl. The ioctl takes an argument structure with the index of the first HPT entry to read out and a set of flags. The flags indicate whether the user is intending to read or write the HPT, and whether to return all entries or only the "bolted" entries (those with the bolted bit, 0x10, set in the first doubleword). This is intended for use in implementing qemu's savevm/loadvm and for live migration. Therefore, on reads, the first pass returns information about all HPTEs (or all bolted HPTEs). When the first pass reaches the end of the HPT, it returns from the read. Subsequent reads only return information about HPTEs that have changed since they were last read. A read that finds no changed HPTEs in the HPT following where the last read finished will return 0 bytes. The format of the data provides a simple run-length compression of the invalid entries. Each block of data starts with a header that indicates the index (position in the HPT, which is just an array), the number of valid entries starting at that index (may be zero), and the number of invalid entries following those valid entries. The valid entries, 16 bytes each, follow the header. The invalid entries are not explicitly represented.
