      PCI: Change all drivers to use pci_device->revision · 44c10138
      Auke Kok 提交于
      Instead of all drivers reading pci config space to get the revision
      ID, they can now use the pci_device->revision member.
      
      This exposes some issues where drivers where reading a word or a dword
      for the revision number, and adding useless error-handling around the
      read. Some drivers even just read it for no purpose of all.
      
      In devices where the revision ID is being copied over and used in what
      appears to be the equivalent of hotpath, I have left the copy code
      and the cached copy as not to influence the driver's performance.
      
      Compile tested with make all{yes,mod}config on x86_64 and i386.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells 提交于
      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.

      [PATCH] Remove more unnecessary driver printk's · d5b20697
      Andy Gospodarek 提交于
      As I promised last week, here is the first pass at removing all
      unnecessary printk's that exist in network device drivers currently in
      promiscuous mode.  The duplicate messages are not needed so they have
      been removed.  Some of these drivers are quite old and might not need an
      update, but I did them all anyway.
      
      I am currently auditing the remaining conditional printk's and will send
      out a patch for those soon.

      [NET]: Merge TSO/UFO fields in sk_buff · 7967168c
      Herbert Xu 提交于
      Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not
      going to scale if we add any more segmentation methods (e.g., DCCP).  So
      let's merge them.
      
      They were used to tell the protocol of a packet.  This function has been
      subsumed by the new gso_type field.  This is essentially a set of netdev
      feature bits (shifted by 16 bits) that are required to process a specific
      skb.  As such it's easy to tell whether a given device can process a GSO
      skb: you just have to and the gso_type field and the netdev's features
      field.
      
      I've made gso_type a conjunction.  The idea is that you have a base type
      (e.g., SKB_GSO_TCPV4) that can be modified further to support new features.
      For example, if we add a hardware TSO type that supports ECN, they would
      declare NETIF_F_TSO | NETIF_F_TSO_ECN.  All TSO packets with CWR set would
      have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO
      packets would be SKB_GSO_TCPV4.  This means that only the CWR packets need
      to be emulated in software.
