| * perf: Expand definition of sysfs format attributeMichael Ellerman2013-05-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it explicit that the format attributes may define overlapping bit ranges. Unfortunately this was left unspecified originally, and all the examples show non-overlapping ranges. I don't believe this is an ABI change, as we are defining something that was previously undefined, but others may disagree. The POWER8 PMU would like to define overlapping ranges, as bit ranges in the event code have different meanings for certain events. It will also allow us to define an overarching "event" field, that encompasses all others. As far as I can see perf is comfortable with this change, however I am not sure if there are any other users of the interface.

Eventually this will help us getting rid of in-kernel gadget drivers and only keep function drivers in the kernel. MUSB was taught that it needs to be built for host-only and device-only modes too. We had this support long ago but it involved a ridiculous amount of ifdefs. Now we have a much cleaner approach. Samsung Exynos4 platform now implements HSIC support. We're introducing support for AB8540 and AB9540 PHYs. MUSB module reinsertion now works as expected, before we were getting -EBUSY being returned by the resource checks done on driver core. DWC3 now has minimum support for TI's AM437x series of SoCs. OMAP5 USB3 PHY learned one extra DPLL configuration values because that PHY is reused in TI's DRA7xx devices. We're introducing support for Faraday fotg210 UDCs. Last, but not least, the usual set of non-critical fixes and cleanups ranging from usage of platform_{get,set}_drvdata to lock improvements.

| * | rbd: don't create sysfs entries for non-mapped snapshotsAlex Elder2013-05-021-20/+0

Inside that directory there are sysfs files that contain information about the image: its size, feature bits, major device number, and so on. Additionally, if that image has any snapshots, a device entry gets created for each of those as a "child" of the mapped device. Each of these is a subdirectory of the mapped device, and each directory contains a few files with information about the snapshot (its snapshot id, size, and feature mask). There is no clear benefit to having those device entries for the snapshots. The information provided via sysfs of of little real value--and all of it is available via rbd CLI commands. If we still wanted to see the kernel's view of this information it could be done much more simply by including it in a single sysfs file for the mapped image. But there *is* a clear cost to supporting them. Every time a snapshot context changes, these entries need to be updated (deleted snapshots removed, new snapshots created). The rbd driver is notified of changes to the snapshot context via callbacks from an osd, and care must be taken to coordinate removal of snapshot data structures with the possibility of one these notifications occurring. Things would be considerably simpler if we just didn't have to maintain device entries for the snapshots. So get rid of them. The ability to map a snapshot of an rbd image will remain; the only thing lost will be the ability to query these sysfs directories for information about snapshots of mapped images.

| * | batman-adv: network coding - add the initial infrastructure codeMartin Hundebøll2013-03-131-0/+8
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Network coding exploits the 802.11 shared medium to allow multiple packets to be sent in a single transmission. In brief, a relay can XOR two packets, and send the coded packet to two destinations. The receivers can decode one of the original packets by XOR'ing the coded packet with the other original packet. This will lead to increased throughput in topologies where two packets cross one relay. In a simple topology with three nodes, it takes four transmissions without network coding to get one packet from Node A to Node B and one from Node B to Node A: 1. Node A ---- p1 ---> Node R Node B 2. Node A Node R <--- p2 ---- Node B 3. Node A <--- p2 ---- Node R Node B 4. Node A Node R ---- p1 ---> Node B With network coding, the relay only needs one transmission, which saves us one slot of valuable airtime: 1. Node A ---- p1 ---> Node R Node B 2. Node A Node R <--- p2 ---- Node B 3. Node A <- p1 x p2 - Node R - p1 x p2 -> Node B The same principle holds for a topology including five nodes. Here the packets from Node A and Node B are overheard by Node C and Node D, respectively. This allows Node R to send a network coded packet to save one transmission: Node A Node B | \ / | | p1 p2 | | \ / | p1 > Node R < p2 | | | / \ | | p1 x p2 p1 x p2 | v / \ v / \ Node C < > Node D More information is available on the open-mesh.org wiki[1]. This patch adds the initial code to support network coding in batman-adv. It sets up a worker thread to do house keeping and adds a sysfs file to enable/disable network coding. The feature is disabled by default, as it requires a wifi-driver with working promiscuous mode, and also because it adds a small delay at each hop.

For each LPSS device, there are two modes of operation related to LTR, the auto mode and the software mode. In the auto mode the LTR is set up by the platform firmware and managed by hardware. Software can only read the LTR register values to monitor the platform's behavior. In the software mode it is possible to use LTR to control the extent to which the platform will use its built-in power management features. This changeset adds support for reading the LPSS devices' LTR registers and exposing their values to user space for monitoring and diagnostics purposes. It re-uses the MMIO mappings created to access the LPSS devices' clock registers for reading the values of the LTR registers and exposes them to user space through sysfs device attributes. Namely, a new atrribute group, lpss_ltr, is created for each LPSS device. It contains three new attributes: ltr_mode, auto_ltr, sw_ltr. The value of the ltr_mode attribute reflects the LTR mode being used at the moment (software vs auto) and the other two contain the actual register values (raw) whose meaning depends on the LTR mode. All of these attributes are read-only. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce user space interface for manipulating hotplug profiles associated with ACPI scan handlers. The interface consists of sysfs directories under /sys/firmware/acpi/hotplug/, one for each hotplug profile, containing an attribute allowing user space to manipulate the enabled field of the corresponding profile. Namely, switching the enabled attribute from '0' to '1' will cause the common hotplug notify handler to be installed for all ACPI namespace objects representing devices matching the scan handler associated with the given hotplug profile (and analogously for the converse switch). Drivers willing to use the new user space interface should add their ACPI scan handlers with the help of new funtion acpi_scan_add_handler_with_hotplug(). Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does a few things. 1) Makes /sys/bus/fcoe/ctlr_{create,destroy} interfaces. These interfaces take an <ifname> and will either create an FCoE Controller or destroy an FCoE Controller depending on which file is written to. The new FCoE Controller will start in a DISABLED state and will not do discovery or login until it is ENABLED. This pause will allow us to configure the FCoE Controller before enabling it. 2) Makes the 'mode' attribute of a fcoe_ctlr_device writale. This allows the user to configure the mode in which the FCoE Controller will start in when it is ENABLED. Possible modes are 'Fabric', or 'VN2VN'. The default mode for a fcoe_ctlr{,_device} is 'Fabric'. Drivers must implement the set_fcoe_ctlr_mode routine to support this feature. libfcoe offers an exported routine to set a FCoE Controller's mode. The mode can only be changed when the FCoE Controller is DISABLED. This patch also removes the get_fcoe_ctlr_mode pointer in the fcoe_sysfs function template, the code in fcoe_ctlr.c to get the mode and the assignment of the fcoe_sysfs function pointer to the fcoe_ctlr.c implementation (in fcoe and bnx2fc). fcoe_sysfs can return that value for the mode without consulting the LLD. 3) Make a 'enabled' attribute of a fcoe_ctlr_device. On a read, fcoe_sysfs will return the attribute's value. On a write, fcoe_sysfs will call the LLD (if there is a callback) to notifiy that the enalbed state has changed. This patch maintains the old FCoE control interfaces as module parameters, but it adds comments pointing out that the old interfaces are deprecated.

It contains an internal EEPROM, allowing to configure up to 12 light patterns. A light pattern is a RGB color plus a fade time. This driver registers a LED class instance with additional sysfs attributes to support basic functions such as setting RGB colors, fade and playing. Other functions are still accessible through the hidraw interface. At this time, the only documentation for the device is the firmware source code from ThingM, plus a few schematics. They are available at: https://github.com/todbot/blink1 This patch is version 3. It updates the name of the source file, the driver and the led sysfs entry, according to comments from Jiri Kosina and Simon Wood.
