While this could be achieved parsing data created with a kvm_trace\nextension this adds too much overhead (at least on embedded PowerPC) slowing\ndown the workloads we wanted to measure.\n\nTherefore this patch adds a in-kernel exit timing statistic to the powerpc kvm\ncode. These statistic is available per vm\u0026vcpu under the kvm debugfs directory.\nAs this statistic is low, but still some overhead it can be enabled via a\n.config entry and should be off by default.\n\nSince this patch touched all powerpc kvm_stat code anyway this code is now\nmerged and simplified together with the exit timing statistic code (still\nworking with exit timing disabled in .config).\n\nSigned-off-by: Christian Ehrhardt \u003cehrhardt@linux.vnet.ibm.com\u003e\nSigned-off-by: Hollis Blanchard \u003chollisb@us.ibm.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" }, { "commit": "7924bd41097ae8991c6d38cef8b1e4058e30d198", "tree": "b39629f81598739eb886126c5f3f8705656ce9cd", "parents": [ "c0ca609c5f874f7d6ae8e180afe79317e1943d22" ], "author": { "name": "Hollis Blanchard", "email": "hollisb@us.ibm.com", "time": "Tue Dec 02 15:51:55 2008 -0600" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Wed Dec 31 16:55:09 2008 +0200" }, "message": "KVM: ppc: directly insert shadow mappings into the hardware TLB\n\nFormerly, we used to maintain a per-vcpu shadow TLB and on every entry to the\nguest would load this array into the hardware TLB. This consumed 1280 bytes of\nmemory (64 entries of 16 bytes plus a struct page pointer each), and also\nrequired some assembly to loop over the array on every entry.\n\nInstead of saving a copy in memory, we can just store shadow mappings directly\ninto the hardware TLB, accepting that the host kernel will clobber these as\npart of the normal 440 TLB round robin. When we do that we need less than half\nthe memory, and we have decreased the exit handling time for all guest exits,\nat the cost of increased number of TLB misses because the host overwrites some\nguest entries.\n\nThese savings will be increased on processors with larger TLBs or which\nimplement intelligent flush instructions like tlbivax (which will avoid the\nneed to walk arrays in software).\n\nIn addition to that and to the code simplification, we have a greater chance of\nleaving other host userspace mappings in the TLB, instead of forcing all\nsubsequent tasks to re-fault all their mappings.\n\nSigned-off-by: Hollis Blanchard \u003chollisb@us.ibm.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n" }, { "commit": "db93f5745d836f81cef0b4101a7c2685eeb55efb", "tree": "970b0dfc93dbbe25eb988b008bbbeffd866f3f23", "parents": [ "5cbb5106f50b4515815cd32cf944958c0d4da83f" ], "author": { "name": "Hollis Blanchard", "email": "hollisb@us.ibm.com", "time": "Wed Nov 05 09:36:18 2008 -0600" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Wed Dec 31 16:52:22 2008 +0200" }, "message": "KVM: ppc: create struct kvm_vcpu_44x and introduce container_of() accessor\n\nThis patch doesn\u0027t yet move all 44x-specific data into the new structure, but\nis the first step down that path.
