We have one\nglobal kretprobe lock to serialise the access to these lists. This causes\nonly one kretprobe handler to execute at a time. Hence affects system\nperformance, particularly on SMP systems and when return probe is set on\nlot of functions (like on all systemcalls).\n\nSolution proposed here gives fine-grain locks that performs better on SMP\nsystem compared to present kretprobe implementation.\n\nSolution:\n\n 1) Instead of having one global lock to protect kretprobe instances\n present in kretprobe object and kretprobe hash table. We will have\n two locks, one lock for protecting kretprobe hash table and another\n lock for kretporbe object.\n\n 2) We hold lock present in kretprobe object while we modify kretprobe\n instance in kretprobe object and we hold per-hash-list lock while\n modifying kretprobe instances present in that hash list. To prevent\n deadlock, we never grab a per-hash-list lock while holding a kretprobe\n lock.\n\n 3) We can remove used_instances from struct kretprobe, as we can\n track used instances of kretprobe instances using kretprobe hash\n table.\n\nTime duration for kernel compilation (\"make -j 8\") on a 8-way ppc64 system\nwith return probes set on all systemcalls looks like this.\n\ncacheline non-cacheline Un-patched kernel\naligned patch \t aligned patch\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m46.784s 9m54.412s 10m2.450s\nuser 40m5.715s 40m7.142s 40m4.273s\nsys 2m57.754s 2m58.583s 3m17.430s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nTime duration for kernel compilation (\"make -j 8) on the same system, when\nkernel is not probed.\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m26.389s\nuser 40m8.775s\nsys 2m7.283s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nSigned-off-by: Srinivasa DS \u003csrinivasa@in.ibm.com\u003e\nSigned-off-by: Jim Keniston \u003cjkenisto@us.ibm.com\u003e\nAcked-by: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: David S.

Removes preemption requirement\n\nFrom: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n\nThis patch fixes a bug with cpu bound guest on kvm-s390. Sometimes it\nwas impossible to deliver a signal to a spinning guest. We used\npreemption as a circumvention. The preemption notifiers called\nvcpu_load, which checked for pending signals and triggered a host\nintercept. But even with preemption, a sigkill was not delivered\nimmediately.\n\nThis patch changes the low level host interrupt handler to check for the\nSIE instruction, if TIF_WORK is set. In that case we change the\ninstruction pointer of the return PSW to rerun the vcpu_run loop. The kvm\ncode sees an intercept reason 0 if that happens. This patch adds accounting\nfor these types of intercept as well.\n\nThe advantages:\n- works with and without preemption\n- signals are delivered immediately\n- much better host latencies without preemption\n\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nSigned-off-by: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "2688905e6a9b3647bf7b452cb0ff2bdb166bd8fe", "tree": "389b9c29eaaa7eb49a9e7d3bb601959fb9d27af8", "parents": [ "c0a18111e571138747a98af18b3a2124df56a0d1" ], "author": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 07 09:22:52 2008 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 07 09:23:00 2008 +0200" }, "message": "[S390] s390: Optimize user and work TIF check\n\nOn return from syscall or interrupt, we have to check if we return to\nuserspace (likely) and if there is work todo (less likely) to decide\nif we handle the work.
