17 years agoDevice tree aware EMAC driver
David Gibson [Thu, 23 Aug 2007 03:56:01 +0000 (13:56 +1000)]
Device tree aware EMAC driver

Based on BenH's earlier work, this is a new version of the EMAC driver
for the built-in ethernet found on PowerPC 4xx embedded CPUs.  The
same ASIC is also found in the Axon bridge chip.  This new version is
designed to work in the arch/powerpc tree, using the device tree to
probe the device, rather than the old and ugly arch/ppc OCP layer.

This driver is designed to sit alongside the old driver (that lies in
drivers/net/ibm_emac and this one in drivers/net/ibm_newemac).  The
old driver is left in place to support arch/ppc until arch/ppc itself
reaches its final demise (not too long now, with luck).

This driver still has a number of things that could do with cleaning
up, but I think they can be fixed up after merging.  Specifically:
- Should be adjusted to properly use the dma mapping API.
Axon needs this.
- Probe logic needs reworking, in conjuction with the general
probing code for of_platform devices.  The dependencies here between
EMAC, MAL, ZMII etc. make this complicated.  At present, it usually
works, because we initialize and register the sub-drivers before the
EMAC driver itself, and (being in driver code) runs after the devices
themselves have been instantiated from the device tree.

ixgbe: driver for Intel(R) 82598 PCI-Express 10GbE adapters (v4)

This patch adds support for the Intel 82598 PCI-Express 10GbE
chipset. Devices will be available on the market soon.

This version of the driver is largely the same as the last release:

  * Driver uses a single RX and single TX queue, each using 1 MSI-X
  irq vector.
  * Driver runs in NAPI mode only
  * Driver is largely multiqueue-ready (TM)

Changes since 20070803:
  * removed wrappers for hardware functions
  * incorporated e1000e-style HW api reorganization code
  * sparse/checkpatch cleanups, namespace cleanups
  * driver prints out extra debugging information at load time
    identifying adapter board number, mac, phy types
  * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h
  * driver update to 1.1.18
  * removed ixgbe.txt which contained no useful info anymore

PS3: changed the way to handle tx skbs

The PS3 virtual network device requires a vlan tag in the sending packet
to select the destination device, ethernet port or wireless.
As the vlan tag field is in the middle of the passed data,
we should insert it into the packet data.
To avoid copying much of the packet data, the driver used two tx descriptors
for one tx skb; one descriptor was for sending a small static
buffer which contained vlan tag and copied header (two mac addresses),
one was for the residual data after the vlan field.

This patch changes the way to insert the vlan tag.  By changing
netdev->hard_header_len, we can make the headroom for moving mac address
fields in the skb buffer. Then we can send one tx skb with
one tx descriptor.  This also gives us a tx throughut gain of approx.
20% according to netperf results.

Unfortunately there's no timeout for how long a packet can sit on
the TX ring after completion before an interrupt is generated, and
we want to have a threshold that's larger than one packet per interrupt.

So we have to have a timer that occasionally cleans the TX ring even
though there hasn't been an interrupt. Instead of setting up a dedicated
timer for this, just clean it in the NAPI poll routine instead.
