      "message": "KVM: MMU: Fix false flooding when a pte points to page table\n\nThe KVM MMU tries to detect when a speculative pte update is not actually\nused by demand fault, by checking the accessed bit of the shadow pte.  If\nthe shadow pte has not been accessed, we deem that page table flooded and\nremove the shadow page table, allowing further pte updates to proceed\nwithout emulation.\n\nHowever, if the pte itself points at a page table and only used for write\noperations, the accessed bit will never be set since all access will happen\nthrough the emulator.\n\nThis is exactly what happens with kscand on old (2.4.x) HIGHMEM kernels.\nThe kernel points a kmap_atomic() pte at a page table, and then\nproceeds with read-modify-write operations to look at the dirty and accessed\nbits.  We get a false flood trigger on the kmap ptes, which results in the\nmmu spending all its time setting up and tearing down shadows.\n\nFix by setting the shadow accessed bit on emulated accesses.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n"

They aren\u0027t\n\u003e _incorrect_ per se, but they are definitely bad.\n\u003e\n\u003e Why?\n\u003e\n\u003e Using random _TIF_WORK_MASK flags is really impolite for doing\n\u003e \"scheduling\" work. There\u0027s a reason that arch/x86/kernel/entry_32.S\n\u003e special-cases the _TIF_NEED_RESCHED flag: we don\u0027t want to exit out of\n\u003e vm86 mode unnecessarily.\n\u003e\n\u003e See the \"work_notifysig_v86\" label, and how it does that\n\u003e \"save_v86_state()\" thing etc etc.\n\nRight, I never liked having to fiddle with those TIF flags. Initially I\nneeded it because the hrtimer base lock could not nest in the rq lock.\nThat however is fixed these days.\n\nCurrently the only reason left to fiddle with the TIF flags is remote\nwakeups. We cannot program a remote cpu\u0027s hrtimer. I\u0027ve been thinking\nabout using the new and improved IPI function call stuff to implement\nhrtimer_start_on().\n\nHowever that does require that smp_call_function_single(.wait\u003d0) works\nfrom interrupt context - /me looks at the latest series from Jens - Yes\nthat does seem to be supported, good.\n\nHere\u0027s a stab at cleaning this stuff up ...\n\nMihai reported test success as well.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nTested-by: Mihai Moldovan \u003cionic@ionic.de\u003e\nCc: Michal Januszewski \u003cspock@gentoo.org\u003e\nCc: Antonino Daplas \u003cadaplas@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

The locker decrements the byte; if the result is 0, then\nthey have the lock.  If the lock is negative, then locker must spin\nuntil the lock is positive again.\n\nWhen there\u0027s contention, the locker spin for 2^16[*] iterations waiting\nto get the lock.  If it fails to get the lock in that time, it adds\nitself to the contention count in the lock and blocks on a per-cpu\nevent channel.\n\nWhen unlocking the spinlock, the locker looks to see if there\u0027s anyone\nblocked waiting for the lock by checking for a non-zero waiter count.\nIf there\u0027s a waiter, it traverses the per-cpu \"lock_spinners\"\nvariable, which contains which lock each CPU is waiting on.  It picks\none CPU waiting on the lock and sends it an event to wake it up.\n\nThis allows efficient fast-path spinlock operation, while allowing\nspinning vcpus to give up their processor time while waiting for a\ncontended lock.\n\n[*] 2^16 iterations is threshold at which 98% locks have been taken\naccording to Thomas Friebel\u0027s Xen Summit talk \"Preventing Guests from\nSpinning Around\".

If there is any contention\nfor physical CPUs (ie, there are more runnable vcpus than cpus), then\nticket locks can cause the system to end up spending 90+% of its time\nspinning.\n\nThe problem is that (v)cpus waiting on a ticket spinlock will be\ngranted access to the lock in strict order they got their tickets.  If\nthe hypervisor scheduler doesn\u0027t give the vcpus time in that order,\nthey will burn timeslices waiting for the scheduler to give the right\nvcpu some time.  In the worst case it could take O(n^2) vcpu scheduler\ntimeslices for everyone waiting on the lock to get it, not counting\nnew cpus trying to take the lock while the log-jam is sorted out.\n\nThese hooks allow a paravirt backend to replace the spinlock\nimplementation.\n\nAt the very least, this could revert the implementation back to the\nold lock algorithm, which allows the next scheduled vcpu to take the\nlock, and has basically fairly good performance.\n\nIt also allows the spinlocks to take advantages of the hypervisor\nfeatures to make locks more efficient (spin and block, for example).\n\nThe cost to native execution is an extra direct call when using a\nspinlock function.  There\u0027s no overhead if CONFIG_PARAVIRT is turned\noff.\n\nThe lock structure is fixed at a single \"unsigned int\", initialized to\nzero, but the spinlock implementation can use it as it wishes.\n\nThanks to Thomas Friebel\u0027s Xen Summit talk \"Preventing Guests from\nSpinning Around\" for pointing out this problem.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Christoph Lameter \u003cclameter@linux-foundation.org\u003e\nCc: Petr Tesarik \u003cptesarik@suse.cz\u003e\nCc: Virtualization \u003cvirtualization@lists.linux-foundation.org\u003e\nCc: Xen devel \u003cxen-devel@lists.xensource.com\u003e\nCc: Thomas Friebel \u003cthomas.friebel@amd.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
