      USB: EHCI: fix timer bug affecting port resume · ee74290b
      Alan Stern 提交于
      This patch (as1652) fixes a long-standing bug in ehci-hcd.  The driver
      relies on status polls to know when to stop port-resume signalling.
      It uses the root-hub status timer to schedule these status polls.  But
      when the driver for the root hub is resumed, the timer is rescheduled
      to go off immediately -- before the port is ready.  When this happens
      the timer does not get re-enabled, which prevents the port resume from
      finishing until some other event occurs.
      
      The symptom is that when a new device is plugged in, it doesn't get
      recognized or enumerated until lsusb is run or something else happens.
      
      The solution is to re-enable the root-hub status timer after every
      status poll while a port resume is in progress.
      
      This bug hasn't surfaced before now because we never used to try to
      suspend the root hub in the middle of a port resume (except by
      coincidence).

      USB: add usb_hcd_{start,end}_port_resume · da0aa716
      Alan Stern 提交于
      This patch (as1649) adds a mechanism for host controller drivers to
      inform usbcore when they have begun or ended resume signalling on a
      particular root-hub port.  The core will then make sure that the root
      hub does not get runtime-suspended while the port resume is going on.
      
      Since commit 596d789a (USB: set hub's
      default autosuspend delay as 0), the system tries to suspend hubs
      whenever they aren't in use.  While a root-hub port is being resumed,
      the root hub does not appear to be in use.  Attempted runtime suspends
      fail because of the ongoing port resume, but the PM core just keeps on
      trying over and over again.  We want to prevent this wasteful effort.

      USB: EHCI: unlink one async QH at a time · 6e0c3339
      Alan Stern 提交于
      This patch (as1648) fixes a regression affecting nVidia EHCI
      controllers.  Evidently they don't like to have more than one async QH
      unlinked at a time.  I can't imagine how they manage to mess it up,
      but at least one of them does.
      
      The patch changes the async unlink logic in two ways:
      
      	Each time an IAA cycle is started, only the first QH on the
      	async unlink list is handled (rather than all of them).
      
      	Async QHs do not all get unlinked as soon as they have been
      	empty for long enough.  Instead, only the last one (i.e., the
      	one that has been on the schedule the longest) is unlinked,
      	and then only if no other unlinks are in progress at the time.
      
      This means that when multiple QHs are empty, they won't be unlinked as
      quickly as before.  That's okay; it won't affect correct operation of
      the driver or add an excessive load.  Multiple unlinks tend to be
      relatively rare in any case.

      USB: EHCI: remove ASS/PSS polling timeout · 55bcdce8
      Alan Stern 提交于
      This patch (as1647) attempts to work around a problem that seems to
      affect some nVidia EHCI controllers.  They sometimes take a very long
      time to turn off their async or periodic schedules.  I don't know if
      this is a result of other problems, but in any case it seems wise not
      to depend on schedule enables or disables taking effect in any
      specific length of time.
      
      The patch removes the existing 20-ms timeout for enabling and
      disabling the schedules.  The driver will now continue to poll the
      schedule state at 1-ms intervals until the controller finally decides
      to obey the most recent command issued by the driver.  Just in case
      this hides a problem, a debugging message will be logged if the
      controller takes longer than 20 polls.
      
      I don't know if this will actually fix anything, but it can't hurt.

      usb: enable usb port device's async suspend. · 192fef18
      Lan Tianyu 提交于
      This patch is to set power.async_suspend for usb port in order
      to allow it to be suspended and resumed asynchronously during
      system sleep transitions.
      
      The power.async_suspend flag is also set for devices that don't have
      suspend or resume callbacks, because otherwise they would make the
      main suspend/resume thread wait for their "asynchronous" children
      (during suspend) or parents (during resume), effectively negating the
      possible gains from executing these devices' suspend and resume
      callbacks asynchronously.
