The driver adds a character device\n(/dev/kvm) that exposes the virtualization capabilities to userspace. Using\nthis driver, a process can run a virtual machine (a \"guest\") in a fully\nvirtualized PC containing its own virtual hard disks, network adapters, and\ndisplay.\n\nUsing this driver, one can start multiple virtual machines on a host.\n\nEach virtual machine is a process on the host; a virtual cpu is a thread in\nthat process. kill(1), nice(1), top(1) work as expected. In effect, the\ndriver adds a third execution mode to the existing two: we now have kernel\nmode, user mode, and guest mode. Guest mode has its own address space mapping\nguest physical memory (which is accessible to user mode by mmap()ing\n/dev/kvm). Guest mode has no access to any I/O devices; any such access is\nintercepted and directed to user mode for emulation.\n\nThe driver supports i386 and x86_64 hosts and guests. All combinations are\nallowed except x86_64 guest on i386 host. For i386 guests and hosts, both pae\nand non-pae paging modes are supported.\n\nSMP hosts and UP guests are supported. At the moment only Intel\nhardware is supported, but AMD virtualization support is being worked on.\n\nPerformance currently is non-stellar due to the naive implementation of the\nmmu virtualization, which throws away most of the shadow page table entries\nevery context switch. We plan to address this in two ways:\n\n- cache shadow page tables across tlb flushes\n- wait until AMD and Intel release processors with nested page tables\n\nCurrently a virtual desktop is responsive but consumes a lot of CPU. Under\nWindows I tried playing pinball and watching a few flash movies; with a recent\nCPU one can hardly feel the virtualization. Linux/X is slower, probably due\nto X being in a separate process.\n\nIn addition to the driver, you need a slightly modified qemu to provide I/O\ndevice emulation and the BIOS.\n\nCaveats (akpm: might no longer be true):\n\n- The Windows install currently bluescreens due to a problem with the\n virtual APIC. We are working on a fix. A temporary workaround is to\n use an existing image or install through qemu\n- Windows 64-bit does not work.

It does this for sync ops, of course, and for\npartial dio writes that must fall back to buffered and for aio ops that saw\nerrors during submission.\n\nThis means that operations that end up waiting, even if they were issued as\naio ops, will not call aio_complete() from dio. Instead we return the return\ncode of the operation and let the aio core call aio_complete().

Fortunately\n bi_next in the original bio is unused at this point so\n we can stuff it in there.\n\n6/ We leak a cloned bio if the target rdev is not usable.\n\nFrom: NeilBrown \u003cneilb@suse.de\u003e\n\nupdate 2:\n\n1/ When aligned requests fail (read error) they need to be retried\n via the normal method (stripe cache). As we cannot be sure that\n we can process a single read in one go (we may not be able to\n allocate all the stripes needed) we store a bio-being-retried\n and a list of bioes-that-still-need-to-be-retried.\n When find a bio that needs to be retried, we should add it to\n the list, not to single-bio...\n\n2/ We were never incrementing \u0027scnt\u0027 when resubmitting failed\n aligned requests.\n\n[akpm@osdl.org: build fix]\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f679623f50545bc0577caf2d0f8675b61162f059", "tree": "7253c48db142ec63e6f22df12dfa2babb3e6129c", "parents": [ "23032a0eb97c8eaae8ac9d17373b53b19d0f5413" ], "author": { "name": "Raz Ben-Jehuda(caro)", "email": "raziebe@gmail.com", "time": "Sun Dec 10 02:20:46 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sun Dec 10 09:57:20 2006 -0800" }, "message": "[PATCH] md: handle bypassing the read cache (assuming nothing fails)\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "23032a0eb97c8eaae8ac9d17373b53b19d0f5413", "tree": "7021309ed7a591c6ae93f7347fb23482cea85163", "parents": [ "0d4ca600fcf5c5f3a0c195ccf37e989b83451dd4" ], "author": { "name": "Raz Ben-Jehuda(caro)", "email": "raziebe@gmail.com", "time": "Sun Dec 10 02:20:45 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sun Dec 10 09:57:20 2006 -0800" }, "message": "[PATCH] md: define raid5_mergeable_bvec\n\nThis will encourage read request to be on only one device, so we will often be\nable to bypass the cache for read requests.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0d4ca600fcf5c5f3a0c195ccf37e989b83451dd4", "tree": "f2847c89d66b2099c3beb55647e00c0fff4fca68", "parents": [ "a3d899839064b6924c3d8a6404dae14c79f657fd" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Sun Dec 10 02:20:44 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sun Dec 10 09:57:20 2006 -0800" }, "message": "[PATCH] md: tidy up device-change notification when an md array is stopped\n\nAn md array can be stopped leaving all the setting still in place, or it can\ntorn down and destroyed. set_capacity and other change notifications only\nhappen in the latter case, but should happen in both.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a3d899839064b6924c3d8a6404dae14c79f657fd", "tree": "0d373bc6e63f5f29d5b3ea5caddbde590f91ad3a", "parents": [ "ee2f344b33b507af23610c8fdfdde38d7c10fb33" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Sun Dec 10 02:20:42 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sun Dec 10 09:57:20 2006 -0800" }, "message": "[PATCH] Fbdev driver for IBM GXT4500P videocards\n\nThis is an fbdev driver for the IBM GXT4500P display card found in some IBM\nSystem P (pSeries) machines.
