      [PATCH] PHY: Add support for configuring the PHY connection interface · e8a2b6a4
      由 Andy Fleming 提交于 
      Most PHYs connect to an ethernet controller over a GMII or MII
interface.  However, a growing number are connected over
different interfaces, such as RGMII or SGMII.

The ethernet driver will tell the PHY what type of connection it
is by setting it manually, or passing it in through phy_connect
(or phy_attach).

Changes include:
* Updates to documentation
* Updates to PHY Lib consumers
* Changes to PHY Lib to add interface support
* Some minor changes to whitespace in phy.h
* gianfar driver now detects interface and passes appropriate
  value to PHY Lib

      [PATCH] Fixed a number of bugs in the PHY Layer · 6b655529
      由 Andy Fleming 提交于 
      * genphy_update_link is now exported
* Added a fix from ncase@xes-inc.com which changes forcing so it
  only updates the link.  Otherwise, it never tries the lower
  values, since it is always overwriting the speed/duplex values
  with the current ones, rather than the intended ones.
* Fixed a bug where bringing up a PHY with no link caused it to
  timeout, and enter forcing mode.  Once in forcing mode,
  plugging in the link didn't autonegotiate.  Now the AN state
  detects the lack of link, and enters the NO_LINK state.  AN
  only times out if the link is up and AN fails
* Cleaned up the PHY_AN case, reducing one level of indentation
  for the timeout code.

      [PATCH] 2.6.18: sb1250-mac: Phylib IRQ handling fixes · 3c3070d7
      由 Maciej W. Rozycki 提交于 
       This patch fixes a couple of problems discovered with interrupt handling
in the phylib core, namely:

1. The driver uses timer and workqueue calls, but does not include
   <linux/timer.h> nor <linux/workqueue.h>.

2. The driver uses schedule_work() for handling interrupts, but does not
   make sure any pending work scheduled thus has been completed before
   driver's structures get freed from memory.  This is especially
   important as interrupts may keep arriving if the line is shared with
   another PHY.

   The solution is to ignore phy_interrupt() calls if the reported device
   has already been halted and calling flush_scheduled_work() from
   phy_stop_interrupts() (but guarded with current_is_keventd() in case
   the function has been called through keventd from the MAC device's
   close call to avoid a deadlock on the netlink lock).

       This patch adds support for interrupt-driven operation of the Broadcom
Gigabit Ethernet PHYs.  I have included device IDs for the parts used on
Broadcom SiByte evaluation boards; more can be added as a need arises.
They are apparently generally software-compatible with one another.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      由 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] Signedness issue in drivers/net/phy/phy_device.c · 84c22d79
      由 Eric Sesterhenn 提交于 
      While checking gcc 4.1 -Wextra warnings, I stumbled across the following
two warnings:

drivers/net/phy/phy_device.c:528: warning: comparison of unsigned expression < 0 is always false
drivers/net/phy/phy_device.c:546: warning: comparison of unsigned expression < 0 is always false

Since phy_read() returns an integer and can return negative values, it seems
to me the best way to get proper error handling working again is to make val
an int.  Currently it is an u32, so the < 0 check always fails.

libphy has no license tag. Something like the attached (untested!) patch
