The PV protocol is also implemented by\nfrontend drivers in other OSes too, such as the BSDs and even Windows.\n\nThe patch is based on the driver from the xen.git pvops kernel tree but\nhas been put through the checkpatch.pl wringer plus several manual\ncleanup passes and review iterations. The driver has been moved from\ndrivers/xen/netback to drivers/net/xen-netback.\n\nOne major change from xen.git is that the guest transmit path (i.e. what\nlooks like receive to netback) has been significantly reworked to remove\nthe dependency on the out of tree PageForeign page flag (a core kernel\npatch which enables a per page destructor callback on the final\nput_page). This page flag was used in order to implement a grant map\nbased transmit path (where guest pages are mapped directly into SKB\nfrags). Instead this version of netback uses grant copy operations into\nregular memory belonging to the backend domain. Reinstating the grant\nmap functionality is something which I would like to revisit in the\nfuture.\n\nNote that this driver depends on 2e820f58f7ad \"xen/irq: implement\nbind_interdomain_evtchn_to_irqhandler for backend drivers\" which is in\nlinux next via the \"xen-two\" tree and is intended for the 2.6.39 merge\nwindow:\n git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/backends\nthis branch has only that single commit since 2.6.38-rc2 and is safe for\ncross merging into the net branch.\n\nSigned-off-by: Ian Campbell \u003cian.campbell@citrix.com\u003e\nReviewed-by: Ben Hutchings \u003cbhutchings@solarflare.com\u003e\nSigned-off-by: David S.

Lastly with Xen 4.0, pages (in debug mode) are\nallocated in descending order (high to low), meaning the guest might\nnever get any MFN\u0027s under the 4GB mark.\n\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nAcked-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Albert Herranz \u003calbert_herranz@yahoo.es\u003e\nCc: Ian Campbell \u003cIan.Campbell@citrix.com\u003e\n" }, { "commit": "5915100106b8f14a38053ad6c03a664d208aeaa2", "tree": "86117ec2860f0a1d1f16fd778ab2e53722871d33", "parents": [ "c1c5413ad58cb73267d328e6020268aa2e50d8ca" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Thu Jun 17 14:22:52 2010 +0100" }, "committer": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Mon Jul 26 23:13:26 2010 -0700" }, "message": "x86: Call HVMOP_pagetable_dying on exit_mmap.\n\nWhen a pagetable is about to be destroyed, we notify Xen so that the\nhypervisor can clear the related shadow pagetable.\n\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\n" }, { "commit": "c1c5413ad58cb73267d328e6020268aa2e50d8ca", "tree": "f2c66141ab8d9fdb7b16a13d4d510ad09b2430ed", "parents": [ "409771d258e9dd71c30f3c9520fd2b796ffc40f0" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Fri May 14 12:44:30 2010 +0100" }, "committer": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Mon Jul 26 23:13:25 2010 -0700" }, "message": "x86: Unplug emulated disks and nics.\n\nAdd a xen_emul_unplug command line option to the kernel to unplug\nxen emulated disks and nics.\n\nSet the default value of xen_emul_unplug depending on whether or\nnot the Xen PV frontends and the Xen platform PCI driver have\nbeen compiled for this kernel (modules or built-in are both OK).\n\nThe user can specify xen_emul_unplug\u003dignore to enable PV drivers on HVM\neven if the host platform doesn\u0027t support unplug.\n\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\n" }, { "commit": "409771d258e9dd71c30f3c9520fd2b796ffc40f0", "tree": "68678275563114e9d381ae587fc80bd4d34a7e90", "parents": [ "99ad198c4978036bb9f7ebd11618b225b77046da" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Fri May 14 12:48:19 2010 +0100" }, "committer": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Mon Jul 26 23:13:25 2010 -0700" }, "message": "x86: Use xen_vcpuop_clockevent, xen_clocksource and xen wallclock.\n\nUse xen_vcpuop_clockevent instead of hpet and APIC timers as main\nclockevent device on all vcpus, use the xen wallclock time as wallclock\ninstead of rtc and use xen_clocksource as clocksource.\nThe pv clock algorithm needs to work correctly for the xen_clocksource\nand xen wallclock to be usable, only modern Xen versions offer a\nreliable pv clock in HVM guests (XENFEAT_hvm_safe_pvclock).\n\nUsing the hpet as clocksource means a VMEXIT every time we read/write to\nthe hpet mmio addresses, pvclock give us a better rating without\nVMEXITs.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7.

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\".
