      ALSA: intel8x0m: wait a bit before warm reset check · 5cd2ad81
      Paul Bolle authored
      At every resume a laptop I use prints this message (at KERN_ERR level):
          ALSA sound/pci/intel8x0m.c:904: AC'97 warm reset still in progress? [0x2]
      
      The thing to note here is that 0x2 corresponds to ICH_AC97COLD. Ie, what
      seems to be happening is that the register involved indicated a warm
      reset for some time (as the ICH_AC97WARM bit was set) but by the time
      the warning is printed, and that same register is checked again, that
      bit is already cleared and only the ICH_AC97COLD bit is still set.
      
      It turns out a warm reset needs some time to settle, but it is currently
      checked right away. The test therefore fails the first time it is done
      and schedule_timeout_uninterruptible() will be called. Once we return
      from that jiffies is already (far) past end_time on this laptop, so we
      exit the loop, print a warning, and exit the function while the warm
      reset actually succeeded.
      
      A way to fix this is to call usleep_range() after writing to the
      register involved. A handful of tests suggest 500 usecs is a safe value.
      (This might punish the "finish cold reset" case, but on this laptop such
      a cold reset apparently never happens, so I can't say for sure.)
      
      While we're at it drop the extra single tick from end_time, as it looks
      rather silly.

      [ALSA] Remove sound/driver.h · 9004acc7
      Takashi Iwai authored
      This header file exists only for some hacks to adapt alsa-driver
      tree.  It's useless for building in the kernel.  Let's move a few
      lines in it to sound/core.h and remove it.
      With this patch, sound/driver.h isn't removed but has just a single
      compile warning to include it.  This should be really killed in
      future.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells authored
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
      of passing regs around manually through all ~1800 interrupt handlers in the
      Linux kernel.
      
      The regs pointer is used in few places, but it potentially costs both stack
      space and code to pass it around.  On the FRV arch, removing the regs parameter
      from all the genirq function results in a 20% speed up of the IRQ exit path
      (ie: from leaving timer_interrupt() to leaving do_IRQ()).
      
      Where appropriate, an arch may override the generic storage facility and do
      something different with the variable.  On FRV, for instance, the address is
      maintained in GR28 at all times inside the kernel as part of general exception
      handling.
      
      Having looked over the code, it appears that the parameter may be handed down
      through up to twenty or so layers of functions.  Consider a USB character
      device attached to a USB hub, attached to a USB controller that posts its
      interrupts through a cascaded auxiliary interrupt controller.  A character
      device driver may want to pass regs to the sysrq handler through the input
      layer which adds another few layers of parameter passing.
      
      I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
      main part of the code on FRV and i386, though I can't test most of the drivers.
      I've also done partial conversion for powerpc and MIPS - these at least compile
      with minimal configurations.
      
      This will affect all archs.  Mostly the changes should be relatively easy.
      Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
      
      	struct pt_regs *old_regs = set_irq_regs(regs);
      
      And put the old one back at the end:
      
      	set_irq_regs(old_regs);
      
      Don't pass regs through to generic_handle_irq() or __do_IRQ().
      
      In timer_interrupt(), this sort of change will be necessary:
      
      	-	update_process_times(user_mode(regs));
      	-	profile_tick(CPU_PROFILING, regs);
      	+	update_process_times(user_mode(get_irq_regs()));
      	+	profile_tick(CPU_PROFILING);
      
      I'd like to move update_process_times()'s use of get_irq_regs() into itself,
      except that i386, alone of the archs, uses something other than user_mode().
      
      Some notes on the interrupt handling in the drivers:
      
       (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
           the input_dev struct.
      
       (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
           something different depending on whether it's been supplied with a regs
           pointer or not.
      
       (*) Various IRQ handler function pointers have been moved to type
           irq_handler_t.
