      misc: Add CARMA DATA-FPGA Access Driver · c186f0e1
      Ira Snyder 提交于
      This driver allows userspace to access the data processing FPGAs on the
      OVRO CARMA board. It has two modes of operation:
      
      1) random access
      
      This allows users to poke any DATA-FPGA registers by using mmap to map
      the address region directly into their memory map.
      
      2) correlation dumping
      
      When correlating, the DATA-FPGA's have special requirements for getting
      the data out of their memory before the next correlation. This nominally
      happens at 64Hz (every 15.625ms). If the data is not dumped before the
      next correlation, data is lost.
      
      The data dumping driver handles buffering up to 1 second worth of
      correlation data from the FPGAs. This lowers the realtime scheduling
      requirements for the userspace process reading the device.

      Intel PTI implementaiton of MIPI 1149.7. · 0b61d2ac
      J Freyensee 提交于
      The PTI (Parallel Trace Interface) driver directs
      trace data routed from various parts in the system out
      through an Intel Penwell PTI port and out of the mobile
      device for analysis with a debugging tool (Lauterbach or Fido).
      Though n_tracesink and n_tracerouter line discipline drivers
      are used to extract modem tracing data to the PTI driver
      and other parts of an Intel mobile solution, the PTI driver
      can be used independent of n_tracesink and n_tracerouter.
      
      You should select this driver if the target kernel is meant for
      an Intel Atom (non-netbook) mobile device containing a MIPI
      P1149.7 standard implementation.

      hpilo: Despecificate driver from iLO generation · 1ce873ab
      dann frazier 提交于
      This driver supports iLO, iLO2 and iLO3. However, comments and Kconfig
      reference only iLO and iLO2. Let's just call it "iLO" to avoid having to
      update strings for each iLO generation. This is similar to the change made
      to hpwdt in commit 36e3ff44.

      add Packet hub driver for Topcliff Platform controller hub · cf4ece53

      Packet hub driver of Topcliff PCH
      
      Topcliff PCH is the platform controller hub that is going to be used in
      Intel's upcoming general embedded platform. All IO peripherals in
      Topcliff PCH are actually devices sitting on AMBA bus. Packet hub is
      a special converter device in Topcliff PCH that translate AMBA transactions
      to PCI Express transactions and vice versa. Thus packet hub helps present
      all IO peripherals in Topcliff PCH as PCIE devices to IA system.
      Topcliff PCH has MAC address and Option ROM data.
      These data are in SROM which is connected to PCIE bus.
      Packet hub driver of Topcliff PCH can access MAC address and Option ROM data in
      SROM via sysfs interface.

      VMware Balloon driver · 453dc659
      Dmitry Torokhov 提交于
      This is a standalone version of VMware Balloon driver.  Ballooning is a
      technique that allows hypervisor dynamically limit the amount of memory
      available to the guest (with guest cooperation).  In the overcommit
      scenario, when hypervisor set detects that it needs to shuffle some
      memory, it instructs the driver to allocate certain number of pages, and
      the underlying memory gets returned to the hypervisor.  Later hypervisor
      may return memory to the guest by reattaching memory to the pageframes and
      instructing the driver to "deflate" balloon.
      
      We are submitting a standalone driver because KVM maintainer (Avi Kivity)
      expressed opinion (rightly) that our transport does not fit well into
      virtqueue paradigm and thus it does not make much sense to integrate with
      virtio.
      
      There were also some concerns whether current ballooning technique is the
      right thing.  If there appears a better framework to achieve this we are
      prepared to evaluate and switch to using it, but in the meantime we'd like
      to get this driver upstream.
      
      We want to get the driver accepted in distributions so that users do not
      have to deal with an out-of-tree module and many distributions have
      "upstream first" requirement.
      
      The driver has been shipping for a number of years and users running on
      VMware platform will have it installed as part of VMware Tools even if it
      will not come from a distribution, thus there should not be additional
      risk in pulling the driver into mainline.  The driver will only activate
      if host is VMware so everyone else should not be affected at all.
