This will guarantee that get_page_unless_zero() can never\nsucceed on any tail page. page_tail-\u003e_mapcount is guaranteed zero and\nis unused for all tail pages of a compound page, so we can simply\naccount the tail page references there and transfer them to\ntail_page-\u003e_count in __split_huge_page_refcount() (in addition to the\nhead_page-\u003e_mapcount).\n\nWhile debugging this s/_count/_mapcount/ change I also noticed get_page is\ncalled by direct-io.c on pages returned by get_user_pages. That wasn\u0027t\nentirely safe because the two atomic_inc in get_page weren\u0027t atomic. As\nopposed to other get_user_page users like secondary-MMU page fault to\nestablish the shadow pagetables would never call any superflous get_page\nafter get_user_page returns. It\u0027s safer to make get_page universally safe\nfor tail pages and to use get_page_foll() within follow_page (inside\nget_user_pages()). get_page_foll() is safe to do the refcounting for tail\npages without taking any locks because it is run within PT lock protected\ncritical sections (PT lock for pte and page_table_lock for\npmd_trans_huge).\n\nThe standard get_page() as invoked by direct-io instead will now take\nthe compound_lock but still only for tail pages. The direct-io paths\nare usually I/O bound and the compound_lock is per THP so very\nfinegrined, so there\u0027s no risk of scalability issues with it. A simple\ndirect-io benchmarks with all lockdep prove locking and spinlock\ndebugging infrastructure enabled shows identical performance and no\noverhead. So it\u0027s worth it. Ideally direct-io should stop calling\nget_page() on pages returned by get_user_pages(). The spinlock in\nget_page() is already optimized away for no-THP builds but doing\nget_page() on tail pages returned by GUP is generally a rare operation\nand usually only run in I/O paths.\n\nThis new refcounting on page_tail-\u003e_mapcount in addition to avoiding new\nRCU critical sections will also allow the working set estimation code to\nwork without any further complexity associated to the tail page\nrefcounting with THP.\n\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nReported-by: Michel Lespinasse \u003cwalken@google.com\u003e\nReviewed-by: Michel Lespinasse \u003cwalken@google.com\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Johannes Weiner \u003cjweiner@redhat.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: \u003cstable@kernel.org\u003e\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fcf634098c00dd9cd247447368495f0b79be12d1", "tree": "77fc98cd461bd52ba3b14e833d54a115ffbbd7bc", "parents": [ "32ea845d5bafc37b7406bea1aee3005407cb0900" ], "author": { "name": "Christopher Yeoh", "email": "cyeoh@au1.ibm.com", "time": "Mon Oct 31 17:06:39 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 31 17:30:44 2011 -0700" }, "message": "Cross Memory Attach\n\nThe basic idea behind cross memory attach is to allow MPI programs doing\nintra-node communication to do a single copy of the message rather than a\ndouble copy of the message via shared memory.\n\nThe following patch attempts to achieve this by allowing a destination\nprocess, given an address and size from a source process, to copy memory\ndirectly from the source process into its own address space via a system\ncall. There is also a symmetrical ability to copy from the current\nprocess\u0027s address space into a destination process\u0027s address space.\n\n- Use of /proc/pid/mem has been considered, but there are issues with\n using it:\n - Does not allow for specifying iovecs for both src and dest, assuming\n preadv or pwritev was implemented either the area read from or\n written to would need to be contiguous.\n - Currently mem_read allows only processes who are currently\n ptrace\u0027ing the target and are still able to ptrace the target to read\n from the target. This check could possibly be moved to the open call,\n but its not clear exactly what race this restriction is stopping\n (reason appears to have been lost)\n - Having to send the fd of /proc/self/mem via SCM_RIGHTS on unix\n domain socket is a bit ugly from a userspace point of view,\n especially when you may have hundreds if not (eventually) thousands\n of processes that all need to do this with each other\n - Doesn\u0027t allow for some future use of the interface we would like to\n consider adding in the future (see below)\n - Interestingly reading from /proc/pid/mem currently actually\n involves two copies! (But this could be fixed pretty easily)\n\nAs mentioned previously use of vmsplice instead was considered, but has\nproblems. Since you need the reader and writer working co-operatively if\nthe pipe is not drained then you block. Which requires some wrapping to\ndo non blocking on the send side or polling on the receive. In all to all\ncommunication it requires ordering otherwise you can deadlock. And in the\nexample of many MPI tasks writing to one MPI task vmsplice serialises the\ncopying.\n\nThere are some cases of MPI collectives where even a single copy interface\ndoes not get us the performance gain we could. For example in an\nMPI_Reduce rather than copy the data from the source we would like to\ninstead use it directly in a mathops (say the reduce is doing a sum) as\nthis would save us doing a copy. We don\u0027t need to keep a copy of the data\nfrom the source. I haven\u0027t implemented this, but I think this interface\ncould in the future do all this through the use of the flags - eg could\nspecify the math operation and type and the kernel rather than just\ncopying the data would apply the specified operation between the source\nand destination and store it in the destination.\n\nAlthough we don\u0027t have a \"second user\" of the interface (though I\u0027ve had\nsome nibbles from people who may be interested in using it for intra\nprocess messaging which is not MPI). This interface is something which\nhardware vendors are already doing for their custom drivers to implement\nfast local communication. And so in addition to this being useful for\nOpenMPI it would mean the driver maintainers don\u0027t have to fix things up\nwhen the mm changes.\n\nThere was some discussion about how much faster a true zero copy would\ngo. Here\u0027s a link back to the email with some testing I did on that:\n\nhttp://marc.info/?l\u003dlinux-mm\u0026m\u003d130105930902915\u0026w\u003d2\n\nThere is a basic man page for the proposed interface here:\n\nhttp://ozlabs.org/~cyeoh/cma/process_vm_readv.txt\n\nThis has been implemented for x86 and powerpc, other architecture should\nmainly (I think) just need to add syscall numbers for the process_vm_readv\nand process_vm_writev. There are 32 bit compatibility versions for\n64-bit kernels.\n\nFor arch maintainers there are some simple tests to be able to quickly\nverify that the syscalls are working correctly here:\n\nhttp://ozlabs.org/~cyeoh/cma/cma-test-20110718.tgz\n\nSigned-off-by: Chris Yeoh \u003cyeohc@au1.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"H.

This is inefficient.\n\nThis adds code to book3s_hv_rmhandlers.S to handle the H_CEDE hcall\nin real mode. When a guest vcpu does an H_CEDE hcall, we now only\nexit to the kernel if all the other vcpus in the same core are also\nidle. Otherwise we mark this vcpu as napping, save state that could\nbe lost in nap mode (mainly GPRs and FPRs), and execute the nap\ninstruction. When the thread wakes up, because of a decrementer or\nexternal interrupt, we come back in at kvm_start_guest (from the\nsystem reset interrupt vector), find the `napping\u0027 flag set in the\npaca, and go to the resume path.\n\nThis has some other ramifications. First, when starting a core, we\nnow start all the threads, both those that are immediately runnable and\nthose that are idle. This is so that we don\u0027t have to pull all the\nthreads out of the guest when an idle thread gets a decrementer interrupt\nand wants to start running.
