e100: Use pci_pme_active to clear PME_Status and disable PME#

2008-09-19T01:42:50+00:00

Currently e100 uses pci_enable_wake() to clear pending wake-up events
and disable PME# during intitialization, but that function is not
suitable for this purpose, because it immediately returns error code
if device_may_wakeup() returns false for given device.

Make e100 use pci_pme_active(), which carries out exactly the
required operations, instead.

e100, fix iomap read

2008-08-27T09:55:35+00:00

There were 2 omitted readb's used on an iomap space. eliminate them
by using ioread8 instead.

dma-mapping: add the device argument to dma_mapping_error()

2008-07-26T19:00:03+00:00

Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER
architecture does:

This enables us to cleanly fix the Calgary IOMMU issue that some devices
are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).

I think that per-device dma_mapping_ops support would be also helpful for
KVM people to support PCI passthrough but Andi thinks that this makes it
difficult to support the PCI passthrough (see the above thread).  So I
CC'ed this to KVM camp.  Comments are appreciated.

A pointer to dma_mapping_ops to struct dev_archdata is added.  If the
pointer is non NULL, DMA operations in asm/dma-mapping.h use it.  If it's
NULL, the system-wide dma_ops pointer is used as before.

If it's useful for KVM people, I plan to implement a mechanism to register
a hook called when a new pci (or dma capable) device is created (it works
with hot plugging).  It enables IOMMUs to set up an appropriate
dma_mapping_ops per device.

The major obstacle is that dma_mapping_error doesn't take a pointer to the
device unlike other DMA operations.  So x86 can't have dma_mapping_ops per
device.  Note all the POWER IOMMUs use the same dma_mapping_error function
so this is not a problem for POWER but x86 IOMMUs use different
dma_mapping_error functions.

The first patch adds the device argument to dma_mapping_error.  The patch
is trivial but large since it touches lots of drivers and dma-mapping.h in
all the architecture.

This patch:

dma_mapping_error() doesn't take a pointer to the device unlike other DMA
operations.  So we can't have dma_mapping_ops per device.

Note that POWER already has dma_mapping_ops per device but all the POWER
IOMMUs use the same dma_mapping_error function.  x86 IOMMUs use device
argument.

e100: Do pci_dma_sync after skb_alloc for proper operation on ixp4xx

2008-06-27T05:30:59+00:00

The E100 device can't work on current kernel (2.6.26-rc6) and will cause
kernel corruption on intel ixdp4xx.

e100: Do suspend/shutdown like e1000

2008-03-05T11:34:28+00:00

This fixes a "trying to free already free IRQ" message and simplifies
the shutdown/suspend code by re-using already existing code when going
to suspend. The code is now symmetric with e100_resume.
