      ehci-hcd.c: fix hanging under higher load · 09c83a45
      Wolfgang Denk 提交于
      This patch solves a problem with USB hanging under higher load on a
      i.MX31 board.  It falls into class of typical USB problems and fixes:
      if you don't understand the real cause, add a delay somewhere.
      
      The problem appeared after introduction of ELF relocation, which
      results in smaller code, which appears to run faster (probably because
      it fits better in the cache); turning off the instruction cache,
      adding debug printf()s and increasing the delay have all been found to
      make the problem go away.
      
      Moving the original "udelay(1)" up in the code to it's new place made
      the problem appear much less frequently. Increasing the delay to 2
      microseconds then made the code run reliably in all (hour-long) tests.
      To be on the safe side, we set it to 5 microseconds here.

      USB: fix Queue Element Transfer Descriptor changes · 8b675fe1
      Wolfgang Denk 提交于
      Commit 3ed16071 "USB: sync Queue Element Transfer Descriptor against
      EHCI spec" added an "__attribute__ ((aligned (32)))" to the
      declaration of struct qTD, as used for example in the Linux kernel as
      well.
      
      However, it turns out that this attribute causes errors in "usb start"
      (like "ERROR: NOT USB_CONFIG_DESC 7b" and similar). Drop the attribute
      again.

      ehci-pci: print hccr, hcor and hc_lenght · af68c066
      Florian Fainelli 提交于
      It is useful to know the EHCI-PCI hccr, hcor and hc_lenght to make sure it was
      successfully registered, and at the correct location.
