      [PATCH] usb_sg_{init,wait,cancel}() · 1e4fece8
      David Brownell authored
      Here are the scatterlist primitives there's been mail about before.
      Now the code has passed basic sanity testing, and is ready to merge
      into Linus' tree to start getting wider use.  Greg, please merge!
      
      To recap, the routines are a utility layer packaging several usb
      core facilities to improve system performance.  It's synchronous.
      The code uses functionality that drivers could use already, but
      generally haven't:
      
          - Request queueing.  This is a big performance win.  It lets
            device drivers help the hcds avoid wasted i/o bandwidth, by
            eliminating irq and scheduling latencies between requests.  It
            can make a huge difference at high speed, when the latencies
            often exceed the time to handle each i/o request!
      
          - The new usb_map_sg() primitives, leveraging IOMMU hardware
            if it's there (better than entry-at-a-time mapping).
      
          - URB_NO_INTERRUPT transfer flag, a hint to hcds that they
            can avoid a 'success irq' for this urb.  Only the urb for
            the last scatterlist entry really needs an IRQ, the others
            can be eliminated or delayed.  (OHCI uses this today, and
            any HCD can safely ignore it.)
      
      The particular functionality in these APIs seemed to meet Matt's
      requirements for usb-storage, so I'd hope the 2.5 usb-storage
      code will start to use these routines in a while.  (And maybe
      those two scanner drivers: hpusbscsi, microtek.)
      
      Brief summary of testing:  this code seems correct for normal
      reads and writes, but the fault paths (including cancelation)
      haven't been tested yet.  Both EHCI and OHCI seem to be mostly
      OK with these more aggressive queued loads, but may need small
      updates (like the two I sent yesterday).  Unfortunately I have
      to report that UHCI and urb queueing will sometimes lock up my
      hardware (PIIX4), so while we're lots better than 2.4 this is
      still a bit of a trouble spot for now.
      
      I'll be making some testing software available shortly, which
      will help track down remaining HCD level problems by giving the
      queuing APIs (and some others!) a more strenuous workout than
      most drivers will, in their day-to-day usage.

      [PATCH] USB-storage: problem clearing halts · 2eea1938
      Matthew Dharm authored
      Greg, attached is a patch designed for diagnostic purposes.  Please apply
      to the 2.5 tree -- yes, we'll be removing this at some point in the future.
      
      It appears that we have a problem clearing halts.  This patch causes a very
      clear message to be printed whenever a usb_stor_clear_halt() manages to
      work.  So far, I haven't seen such a thing happen.  And I've seen _lots_ of
      STALL conditions.
      
      This problem has likely been around for a while... however, it hasn't been
      noticed before because usb-storage was difficult to use because of other
      bugs.  Heck, the most recent 'bk pull' is the first one for me in _months_
      which let me boot all the way into X11.
      
      I'm going to hold my patch queue until this is resolved.  On my test setup,
      it's easy to see this failing.  I've tried with 4 different devices, with
      both UHCI and EHCI drivers.  I don't want to confuse this problem with
      other patches...
      
      'result' in this function always seems to be -32.  Which is odd, because
      control endpoints shouldn't do that.
      
      I'm open to suggestions as to where to look for this bug, but my instincts
      are telling me that this is a core or HCD issue, not a usb-storage issue.
      
      On a positive note, this means that the error-recovery system gets a good
      workout.

      [ARM] Fix sa1111 IRQ handling · 99afe913
      Russell King authored
      We must clear down all currently pending IRQs before servicing any
      IRQ on the chip.  This prevents immediate recursion into the
      interrupt handling paths when we service the first IRQ.

      This cset updates the SA1111 core, PCMCIA, OHCI and keyboard drivers,

      this implements initial suspend/resume support for the SA1111 in the

      interface for suspend/resume support.

      [PATCH] ohci-hcd, paranoia · 86cdffc9
      David Brownell authored
      In a test where some memory corruption happened, I noticed an
      oops (null pointer exception in_irq) that's avoidable.  Here's
      a patch that avoids it ... anyone seeing the err() is likely
      to hang some process, but that's better than the alternative.
      (Also inlines some used-once routines, saving a bit of space
      to make up for the new diagnostic.)

      [PATCH] ehci-hcd, urb queuing · c5375618
      David Brownell authored
      In doing some more extensive testing of the urb queueing behavior,
      I noticed that (a) IOC wasn't always being set for each urb, while
      for now it needs to be set; (b) a qh patchup wasn't done quite
      where it should be.  This resolves those two issues, as well
      as making it a bit less noisy to unlink lots of urbs at the once.

      [PATCH] usbcore misc cleanup · 846f917c
      David Brownell authored
      This has minor usbcore cleanups:
      
      DOC:
          - the changes passing a usb_interface to driver probe() and disconnect()
            weren't reflected in their adjacent docs.  likewise they still said
            it was possible to get a null usb_device_id (no more).
      
          - the (root) hub API restrictions from rmk's ARM patch weren't
            flagged
      
          - mention the non-dma-coherent cache issue for usb_buffer_alloc()
      
          - mention disconnect() cleanup issue with usb_{control,bulk}_msg()
            [ you can't cancel those urbs from disconnect() ]
      
      CODE
          - make driver ioctl() use 'usb_interface' too ... this update
            also resolves an old 'one instance per device' bad assumption
      
          - module locking on driver->ioctl() was goofy, kept BKL way too
            long and didn't try_inc_mod_count() like the rest of usbcore
      
          - hcd unlink code treated iso inappropriately like interrupt;
            only interrupt still wants that automagic mode
      
          - move iso init out of ohci into shared submit_urb logic
      
          - remove interrupt transfer length restriction; hcds that don't
            handle packetization (just like bulk :) should be updated,
            but device drivers won't care for now.

      [PATCH] alloc_disk/put_disk · 2e26b412
      Alexander Viro authored
      Beginning of proper refcounting.  New helpers introduced, several drivers
      switched to using them for dynamic allocation of gendisks.  Once everything
      is switched (and that will be way easier than per-drive gendisks series)
      we will be able to add sane reference counts on gendisk, at which point
      we can safely put pointer to gendisk in struct block_device / struct request
      and we had pretty much won - from that point it's pretty straightforward
      crapectomy in drivers.

      Alexander Viro authored
      get_gendisk() now takes dev_t (instead of kdev_t) and gets an additional
      argument - int *part.  Set to 0 for non-partitioned, partition number
      for partititoned.  Callers updated.  Yes, I hate passing return values
      that way ;-/  We need that since old "minor(dev) - disk->first_minor"
      doesn't work for stuff with non-trivial numbers (e.g. floppy) and
      get_gendisk() really has to return both gendisk and partition number.
      Fortunately, amount of callers of gendisk() is about to drop RSN big way...
