There exist\n more than one function for allocating and freeing the buffers:\n currently these 3 are used dma_{alloc, free}_coherent,\n dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent.\n\n For most of the systems these calls are almost equivalent and can be\n interchanged. For others, especially the truly non-coherent ones\n (like ARM), the difference can be easily noticed in overall driver\n performance. Sadly not all architectures provide implementations for\n all of them, so the drivers might need to be adapted and cannot be\n easily shared between different architectures. The provided patches\n unify all these functions and hide the differences under the already\n existing dma attributes concept. The thread with more references is\n available here:\n\n http://www.spinics.net/lists/linux-sh/msg09777.html\n\n These patches are also a prerequisite for unifying DMA-mapping\n implementation on ARM architecture with the common one provided by\n dma_map_ops structure and extending it with IOMMU support. More\n information is available in the following thread:\n\n http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819\n\n More works on dma-mapping framework are planned, especially in the\n area of buffer sharing and managing the shared mappings (together with\n the recently introduced dma_buf interface: commit d15bd7ee445d\n \"dma-buf: Introduce dma buffer sharing mechanism\").\n\n The patches in the current set introduce a new alloc/free methods\n (with support for memory attributes) in dma_map_ops structure, which\n will later replace dma_alloc_coherent and dma_alloc_writecombine\n functions.\"\n\nPeople finally started piping up with support for merging this, so I\u0027m\nmerging it as the last of the pending stuff from the merge window.\nLooks like pohmelfs is going to wait for 3.5 and more external support\nfor merging.\n\n* \u0027for-linus\u0027 of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:\n common: DMA-mapping: add

Parse and upload ACPI0007 (or PROCESSOR_TYPE) information to the\n hypervisor - aka P-states (cpufreq data).\n 2). Upload the the Cx state information (cpuidle data).\n 3). Inhibit CPU frequency scaling drivers from loading.\n\nThe reason for wanting to solve 1) and 2) is such that the Xen hypervisor\nis the only one that knows the CPU usage of different guests and can\nmake the proper decision of when to put CPUs and packages in proper states.\nUnfortunately the hypervisor has no support to parse ACPI DSDT tables, hence it\nneeds help from the initial domain to provide this information. The reason\nfor 3) is that we do not want the initial domain to change P-states while the\nhypervisor is doing it as well - it causes rather some funny cases of P-states\ntransitions.\n\nFor this to work, the driver parses the Power Management data and uploads said\ninformation to the Xen hypervisor. It also calls acpi_processor_notify_smm()\nto inhibit the other CPU frequency scaling drivers from being loaded.\n\nEverything revolves around the \u0027struct acpi_processor\u0027 structure which\ngets updated during the bootup cycle in different stages. At the startup, when\nthe ACPI parser starts, the C-state information is processed (processor_idle)\nand saved in said structure as \u0027power\u0027 element. Later on, the CPU frequency\nscaling driver (powernow-k8 or acpi_cpufreq), would call the the\nacpi_processor_* (processor_perflib functions) to parse P-states information\nand populate in the said structure the \u0027performance\u0027 element.\n\nSince we do not want the CPU frequency scaling drivers from loading\nwe have to call the acpi_processor_* functions to parse the P-states and\ncall \"acpi_processor_notify_smm\" to stop them from loading.\n\nThere is also one oddity in this driver which is that under Xen, the\nphysical online CPU count can be different from the virtual online CPU count.\nMeaning that the macros \u0027for_[online|possible]_cpu\u0027 would process only\nup to virtual online CPU count. We on the other hand want to process\nthe full amount of physical CPUs. For that, the driver checks if the ACPI IDs\ncount is different from the APIC ID count - which can happen if the user\nchoose to use dom0_max_vcpu argument. In such a case a backup of the PM\nstructure is used and uploaded to the hypervisor.\n\n[v1-v2: Initial RFC implementations that were posted]\n[v3: Changed the name to passthru suggested by Pasi Kärkkäinen \u003cpasik@iki.fi\u003e]\n[v4: Added vCPU !\u003d pCPU support - aka dom0_max_vcpus support]\n[v5: Cleaned up the driver, fix bug under Athlon XP]\n[v6: Changed the driver to a CPU frequency governor]\n[v7: Jan Beulich \u003cjbeulich@suse.com\u003e suggestion to make it a cpufreq scaling driver\n made me rework it as driver that inhibits cpufreq scaling driver]\n[v8: Per Jan\u0027s review comments, fixed up the driver]\n[v9: Allow to continue even if acpi_processor_preregister_perf.. fails]\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\n" }, { "commit": "ead1d01425bbd28c4354b539caa4075bde00ed72", "tree": "a74187ed30691cc95455de39d3c3457ab4ccd37c", "parents": [ "42c46e6ba5461fcab289bf4a1b7160f94c10aa28" ], "author": { "name": "Jan Beulich", "email": "JBeulich@suse.com", "time": "Wed Mar 14 12:34:19 2012 -0400" }, "committer": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Wed Mar 14 12:34:19 2012 -0400" }, "message": "xen: constify all instances of \"struct attribute_group\"\n\nThe functions these get passed to have been taking pointers to const\nsince at least 2.6.16.\n\nSigned-off-by: Jan Beulich \u003cjbeulich@suse.com\u003e\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\n" }, { "commit": "42c46e6ba5461fcab289bf4a1b7160f94c10aa28", "tree": "ac81c4586d8925158f38d59a5c4134eeabb00440", "parents": [ "cf8e019b523a8caa95b56ff0ce62a4856b14395f" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Tue Mar 13 18:30:44 2012 +0000" }, "committer": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Tue Mar 13 19:24:52 2012 -0400" }, "message": "xen/xenbus: ignore console/0\n\nUnfortunately xend creates a bogus console/0 frotend/backend entry pair\non xenstore that console backends cannot properly cope with.\nAny guest behavior that is not completely ignoring console/0 is going\nto either cause problems with xenconsoled or qemu.\nReturning 0 or -ENODEV from xencons_probe is not enough because it is\ngoing to cause the frontend state to become 4 or 6 respectively.\nThe best possible thing we can do here is just ignore the entry from\nxenbus_probe_frontend.\n\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\n" }, { "commit": "bd0d5aa417d40d6b996fb7b5c926bcecd56c8984", "tree": "7e05120b899c9bcabe1422d0c582c49d97cd1037", "parents": [ "73c154c60be106b47f15d1111fc2d75cc7a436f2" ], "author": { "name": "Jan Beulich", "email": "JBeulich@suse.com", "time": "Mon Mar 05 17:11:31 2012 +0000" }, "committer": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Tue Mar 13 14:15:29 2012 -0400" }, "message": "xenbus: don\u0027t free other end details too early\n\nThe individual drivers\u0027 remove functions could legitimately attempt to\naccess this information (for logging messages if nothing else).
