2012-10-06ACPI: Add new sysfs interface to export device descriptionLance Ortiz
Add support to export the device description obtained from the ACPI _STR method, if one exists for a device, to user-space via a sysfs interface. This new interface provides a standard and platform neutral way for users to obtain the description text stored in the ACPI _STR method. If no _STR method exists for the device, no sysfs 'description' file will be created. The 'description' file will be located in the /sys/devices/ directory using the device's path. /sys/device/<bus>/<bridge path>/<device path>.../firmware_node/description Example: /sys/devices/pci0000:00/0000:00.07.0/0000:0e:00.0/firmware_node/description It can also be located using the ACPI device path, for example: /sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/PNP0A08:00/device:13/device:15/description /sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/ACPI0004:01/ACPI0007:02/description Execute the 'cat' command on the 'description' file to obtain the description string for that device. This patch also includes documentation describing how the new sysfs interface works Changes from v1-v2 based on comments by Len Brown and Fengguang Wu * Removed output "No Description" and leaving a NULL attribute if the _STR method failed to evaluate. * In acpi_device_remove_files() removed the redundent check of dev->pnp.str_obj before calling free. This check triggered a message from smatch. Signed-off-by: Lance Ortiz <lance.ortiz@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around.

2012-10-01rbd: add an rbd features fieldAlex Elder
Record the features values for each rbd image and each of its snapshots. This is really something that only becomes meaningful for version 2 images, so this is just putting in place code that will form common infrastructure. It may be useful to expand the sysfs entries--and therefore the information we maintain--for the image and for each snapshot. But I'm going to hold off doing that until we start making active use of the feature bits. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
2012-10-01rbd: kill create_snap sysfs entryAlex Elder
Josh proposed the following change, and I don't think I could explain it any better than he did: From: Josh Durgin <josh.durgin@inktank.com> Date: Tue, 24 Jul 2012 14:22:11 -0700 To: ceph-devel <ceph-devel@vger.kernel.org> Message-ID: <500F1203.9050605@inktank.com> Right now the kernel still has one piece of rbd management duplicated from the rbd command line tool: snapshot creation. There's nothing special about snapshot creation that makes it advantageous to do from the kernel, so I'd like to remove the create_snap sysfs interface. That is, /sys/bus/rbd/devices/<id>/create_snap would be removed. Does anyone rely on the sysfs interface for creating rbd snapshots? If so, how hard would it be to replace with: rbd snap create pool/image@snap Is there any benefit to the sysfs interface that I'm missing? Josh This patch implements this proposal, removing the code that implements the "snap_create" sysfs interface for rbd images. As a result, quite a lot of other supporting code goes away.

2012-10-01rbd: define rbd_dev_image_id()Alex Elder
New format 2 rbd images are permanently identified by a unique image id. Each rbd image also has a name, but the name can be changed. A format 2 rbd image will have an object--whose name is based on the image name--which maps an image's name to its image id. Create a new function rbd_dev_image_id() that checks for the existence of the image id object, and if it's found, records the image id in the rbd_device structure. Create a new rbd device attribute (/sys/bus/rbd/<num>/image_id) that makes this information available. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>

2012-09-10usb : Add sysfs files to control port power.Lan Tianyu
This patch adds two sysfs files for each usb hub port to allow userspace to control the port power policy. For an upcoming Intel xHCI roothub, this will translate into ACPI calls to completely power off or power on the port. As a reminder, when these ports are completely powered off, the USB host and device will see a physical disconnect. All future USB device connections will be lost, and the device will not be able to signal a remote wakeup. The control sysfs file can be written to with two options: "on" - port power must be on. "off" - port must be off.

2012-09-10usb: make usb port a real deviceLan Tianyu
This patch turns each USB port on a hub into a new struct device. This new device has the USB hub interface device as its parent. The port devices are stored in a new structure (usb_port), and an array of usb_ports are dynamically allocated once we know how many ports the USB hub has. Move the port_owner variable out of usb_hub and into this new structure. A new file will be created in the hub interface sysfs directory, so add documentation.

2012-09-10regulator: core: Support bypass modeMark Brown
Many regulators support a bypass mode where they simply switch their input supply to the output. This is mainly used in low power retention states where power consumption is extremely low so higher voltage or less clean supplies can be used. Support this by providing ops for the drivers and a consumer API which allows the device to be put into bypass mode if all consumers enable it and the machine enables permission for this. This is not supported as a mode since the existing modes are rarely used due to fuzzy definition and mostly redundant with modern hardware which is able to respond promptly to load changes.

2012-09-09acpi-cpufreq: Add support for disabling dynamic overclockingAndre Przywara
One feature present in powernow-k8 that isn't present in acpi-cpufreq is support for enabling or disabling AMD's core performance boost technology. This patch adds support to acpi-cpufreq, but also includes support for Intel's dynamic acceleration. The original boost disabling sysfs file was per CPU, but acted globally. Also the naming (cpb) was at least not intuitive. So lets introduce a single file simply called "boost", which sits once in /sys/devices/system/cpu/cpufreq. This should be the only way of using this feature, so add documentation about the rationale and the usage. A following patch will re-introduce the cpb knob for compatibility reasons on AMD CPUs. Per-CPU boost switching is possible, but not trivial and is thus postponed to a later patch series. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Rafael J.

2012-09-07ima: add appraise action keywords and default rulesMimi Zohar
Unlike the IMA measurement policy, the appraise policy can not be dependent on runtime process information, such as the task uid, as the 'security.ima' xattr is written on file close and must be updated each time the file changes, regardless of the current task uid. This patch extends the policy language with 'fowner', defines an appraise policy, which appraises all files owned by root, and defines 'ima_appraise_tcb', a new boot command line option, to enable the appraise policy. Changelog v3: - separate the measure from the appraise rules in order to support measuring without appraising and appraising without measuring. - change appraisal default for filesystems without xattr support to fail - update default appraise policy for cgroups Changelog v1: - don't appraise RAMFS (Dmitry Kasatkin) - merged rest of "ima: ima_must_appraise_or_measure API change" commit (Dmtiry Kasatkin) ima_must_appraise_or_measure() called ima_match_policy twice, which searched the policy for a matching rule. Once for a matching measurement rule and subsequently for an appraisal rule. Searching the policy twice is unnecessary overhead, which could be noticeable with a large policy. The new version of ima_must_appraise_or_measure() does everything in a single iteration using a new version of ima_match_policy(). It returns IMA_MEASURE, IMA_APPRAISE mask. With the use of action mask only one efficient matching function is enough. Removed other specific versions of matching functions.

2012-08-17ext4: make the zero-out chunk size tunableZheng Liu
Currently in ext4 the length of zero-out chunk is set to 7 file system blocks. But if an inode has uninitailized extents from using fallocate to preallocate space, and the workload issues many random writes, this can cause a fragmented extent tree that will unnecessarily grow the extent tree. So create a new sysfs tunable, extent_max_zeroout_kb, which controls the maximum size where blocks will be zeroed out instead of creating a new uninitialized extent. The default of this has been sent to 32kb.

It shares the same device ID with deep S3(0x00120031), and the deep S3(resume on lid open) is disable by default.

This makes it easier to handle GART-like IOMMUs with the IOMMU-API because now the start-address and the size of the domain address space can be queried. Besides that there are a few cleanups and fixes for the NVidia Tegra IOMMU drivers and the reworked init-code for the AMD IOMMU. The latter is from my patch-set to support interrupt remapping.

When an privileged guest is booted it is present with virtual CPUs, which might have an 1:1 to physical CPUs but usually don't. This provides mechanism to offline/online physical CPUs. Bug-fixes for: * Coverity found fixes in the console and ACPI processor driver. * PVonHVM kexec fixes along with some cleanups. * Pages that fall within E820 gaps and non-RAM regions (and had been released to hypervisor) would be populated back, but potentially in non-RAM regions." * tag 'stable/for-linus-3.6-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen: populate correct number of pages when across mem boundary (v2) xen PVonHVM: move shared_info to MMIO before kexec xen: simplify init_hvm_pv_info xen: remove cast from HYPERVISOR_shared_info assignment xen: enable platform-pci only in a Xen guest xen/pv-on-hvm kexec: shutdown watches from old kernel xen/x86: avoid updating TLS descriptors if they haven't changed xen/x86: add desc_equal() to compare GDT descriptors xen/mm: zero PTEs for non-present MFNs in the initial page table xen/mm: do direct hypercall in xen_set_pte() if batching is unavailable xen/hvc: Fix up checks when the info is allocated. xen/acpi: Fix potential memory leak. xen/mce: add .poll method for mcelog device driver xen/mce: schedule a workqueue to avoid sleep in atomic context xen/pcpu: Xen physical cpus online/offline sys interface xen/mce: Register native mce handler as vMCE bounce back point x86, MCE, AMD: Adjust initcall sequence for xen xen/mce: Add mcelog support for Xen platform
