The basic concept\nof \"crashme\" is generating random assembly code and trying to execute it.\n\nAfter some fixes on emulator insn validity judgment, we found it\u0027s hard to\nget the current emulator handle the invalid instructions correctly, for the\n#UD trap for hypercall patching caused troubles. The problem is, if the opcode\nitself was OK, but combination of opcode and modrm_reg was invalid, and one\noperand of the opcode was memory (SrcMem or DstMem), the emulator will fetch\nthe memory operand first rather than checking the validity, and may encounter\nan error there. For example, \".byte 0xfe, 0x34, 0xcd\" has this problem.\n\nIn the patch, we simply check that if the invalid opcode wasn\u0027t vmcall/vmmcall,\nthen return from emulate_instruction() and inject a #UD to guest. With the\npatch, the guest had been running for more than 12 hours.\n\nSigned-off-by: Feng (Eric) Liu \u003ceric.e.liu@intel.com\u003e\nSigned-off-by: Sheng Yang \u003csheng.yang@intel.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "d7824fff896a1698a07a8046dc362f4500c302f7", "tree": "249e23ec224bc621bea1ef24fa83f5a749d6b35b", "parents": [ "7ec54588210df29ea637e6054489bc942c0ef371" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Sun Dec 30 12:29:05 2007 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Wed Jan 30 18:01:21 2008 +0200" }, "message": "KVM: MMU: Avoid calling gfn_to_page() in mmu_set_spte()\n\nSince gfn_to_page() is a sleeping function, and we want to make the core mmu\nspinlocked, we need to pass the page from the walker context (which can sleep)\nto the shadow context (which cannot).\n\n[marcelo: avoid recursive locking of mmap_sem]\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "774ead3ad9bcbc05ef6aaebb9bdf8b4c3126923b", "tree": "0395ee65292f99bd43ab2cd07beb554d99cb096f", "parents": [ "b93463aa59d67b21b4921e30bd5c5dcc7c35ffbd" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Wed Dec 26 13:57:04 2007 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Wed Jan 30 18:01:20 2008 +0200" }, "message": "KVM: Disable vapic support on Intel machines with FlexPriority\n\nFlexPriority accelerates the tpr without any patching.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "b209749f528488c4c0d20a42c0fbcbf49e6933b3", "tree": "0e0a24225a5c6bca1c1986cc0daaf8753424cfe6", "parents": [ "565f1fbd9d2f766dcfed5db90b89ef80afe8b49a" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Mon Oct 22 16:50:39 2007 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Wed Jan 30 18:01:20 2008 +0200" }, "message": "KVM: local APIC TPR access reporting facility\n\nAdd a facility to report on accesses to the local apic tpr even if the\nlocal apic is emulated in the kernel.

This patch changes the GPIO API to allow for setting\nof multiple GPIOs at once; rather than being passed an integer, we pass\na bitmask and provide a translation function. The above code would now\nlook like this:\n\n geode_gpio_set(geode_gpio(14)|geode_gpio(15), GPIO_OUTPUT_VAL);\n geode_gpio_set(geode_gpio(14)|geode_gpio(15), GPIO_OUTPUT_ENABLE);\n\nSince there are no upstream users of the GPIO API yet (afaik), best to\nchange this now. This also adds a bit of sanity checking; it is no\nlonger possible to use a GPIO above 28.\n\nNote the semantics of geode_gpio_isset() have changed:\ngeode_gpio_isset(geode_gpio(3)|geode_gpio(4), ...)\nwill only return true iff both GPIOs are set.\n\nSigned-off-by: Andres Salomon \u003cdilinger@debian.org\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "093af8d7f0ba3c6be1485973508584ef081e9f93", "tree": "0a2db2401e09764e654efafbea60f6d5d6894dcd", "parents": [ "11201e603d28a1cb7a4bb1d65f39e61629c97a28" ], "author": { "name": "Yinghai Lu", "email": "Yinghai.Lu@Sun.COM", "time": "Wed Jan 30 13:33:32 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 30 13:33:32 2008 +0100" }, "message": "x86_32: trim memory by updating e820\n\nwhen MTRRs are not covering the whole e820 table, we need to trim the\nRAM and need to update e820.\n\nreuse some code on 64-bit as well.\n\nhere need to add early_get_cap and use it in early_cpu_detect, and move\nmtrr_bp_init early.\n\nThe code successfully trimmed the memory map on Justin\u0027s system:\n\nfrom:\n\n [ 0.000000] BIOS-e820: 0000000100000000 - 000000022c000000 (usable)\n\nto:\n\n [ 0.000000] modified: 0000000100000000 - 0000000228000000 (usable)\n [ 0.000000] modified: 0000000228000000 - 000000022c000000 (reserved)\n\nAccording to Justin it makes quite a difference:\n\n| When I boot the box without any trimming it acts like a 286 or 386,\n| takes about 10 minutes to boot (using raptor disks).\n\nSigned-off-by: Yinghai Lu \u003cyinghai.lu@sun.com\u003e\nTested-by: Justin Piszcz \u003cjpiszcz@lucidpixels.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "1bdbdaacf774f2979ed4cb0c4a4316c9e578c897", "tree": "9fd0b72aec27c32288f016790b899a05c25a8f69", "parents": [ "8b2f7ffffe7f247ba237322fee78c528ba88f16b" ], "author": { "name": "Bernhard Walle", "email": "bwalle@suse.de", "time": "Wed Jan 30 13:33:28 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 30 13:33:28 2008 +0100" }, "message": "x86, rtc: make CONFIG_HPET_EMULATE_RTC usable from modules\n\nenabled, then interrupts don\u0027t work for the rtc-cmos driver which results in\nRTC_AIE*, RTC_PIE* and RTC_ALM being unusable.

"message": "x86, 32-bit: trim memory not covered by wb mtrrs\n\nOn some machines, buggy BIOSes don\u0027t properly setup WB MTRRs to cover all\navailable RAM, meaning the last few megs (or even gigs) of memory will be\nmarked uncached. Since Linux tends to allocate from high memory addresses\nfirst, this causes the machine to be unusably slow as soon as the kernel\nstarts really using memory (i.e. right around init time).\n\nThis patch works around the problem by scanning the MTRRs at boot and\nfiguring out whether the current end_pfn value (setup by early e820 code)\ngoes beyond the highest WB MTRR range, and if so, trimming it to match. A\nfairly obnoxious KERN_WARNING is printed too, letting the user know that\nnot all of their memory is available due to a likely BIOS bug.\n\nSomething similar could be done on i386 if needed, but the boot ordering\nwould be slightly different, since the MTRR code on i386 depends on the\nboot_cpu_data structure being setup.\n\nThis patch fixes a bug in the last patch that caused the code to run on\nnon-Intel machines (AMD machines apparently don\u0027t need it and it\u0027s untested\non other non-Intel machines, so best keep it off).\n\nFurther enhancements and fixes from:\n\n Yinghai Lu \u003cYinghai.Lu@Sun.COM\u003e\n Andi Kleen \u003cak@suse.de\u003e\n\nSigned-off-by: Jesse Barnes \u003cjesse.barnes@intel.com\u003e\nTested-by: Justin Piszcz \u003cjpiszcz@lucidpixels.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: \"Eric W.
