62ce43ccc8 More conversions of drivers to use the PCI parent DMA tag. 2012-03-12 18:15:08 +00:00

aa15e881bb Respect phy-handle property in Ethernet nodes of the device tree.
This lets specify whereabouts of the parent PHY for a given MAC node
(and get rid of ugly kludges in mge(4) and tsec(4)).

8e5d93dbb4 Convert the PHY drivers to honor the mii_flags passed down and convert
the NIC drivers as well as the PHY drivers to take advantage of the
mii_attach() introduced in r213878 to get rid of certain hacks. For
the most part these were:
- Artificially limiting miibus_{read,write}reg methods to certain PHY
  addresses; we now let mii_attach() only probe the PHY at the desired
  address(es) instead.
- PHY drivers setting MIIF_* flags based on the NIC driver they hang
  off from, partly even based on grabbing and using the softc of the
  parent; we now pass these flags down from the NIC to the PHY drivers
  via mii_attach(). This got us rid of all such hacks except those of
  brgphy() in combination with bce(4) and bge(4), which is way beyond
  what can be expressed with simple flags.

While at it, I took the opportunity to change the NIC drivers to pass
up the error returned by mii_attach() (previously by mii_phy_probe())
and unify the error message used in this case where and as appropriate
as mii_attach() actually can fail for a number of reasons, not just
because of no PHY(s) being present at the expected address(es).

db5ef4fc77 Convert Marvell ARM platforms to FDT convention.
The following systems are involved:

  - DB-88F5182
  - DB-88F5281
  - DB-88F6281
  - DB-78100
  - SheevaPlug

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Marvell ARM SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
    good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.

d6bdd318a3 Assorted fixes for mge(4).
- Use proper map for the busdma sync on mge descriptor.
- Remove unnecesary busdma sync.
- Eliminate redundant locking in mge_reinit_rx() (just assert).
- Kill unused variable.

18159f6a49 Introduce MII_ADDR_BASE option on ARM, which allows to override the default
per platform requirements.

Notes:
- Only used by mge(4) at the moment.

- This is very simplified approach and should be replaced by some long-term
  solution for managing the board/platform configuration (among others the
  MAC-PHY binding info).

eb956cd041 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

1abcdbd127 When user_frac in the polling subsystem is low it is going to busy the
CPU for too long period than necessary.  Additively, interfaces are kept
polled (in the tick) even if no more packets are available.
In order to avoid such situations a new generic mechanism can be
implemented in proactive way, keeping track of the time spent on any
packet and fragmenting the time for any tick, stopping the processing
as soon as possible.

In order to implement such mechanism, the polling handler needs to
change, returning the number of packets processed.
While the intended logic is not part of this patch, the polling KPI is
broken by this commit, adding an int return value and the new flag
IFCAP_POLLING_NOCOUNT (which will signal that the return value is
meaningless for the installed handler and checking should be skipped).

Bump __FreeBSD_version in order to signal such situation.

5817716faf mge(4): fix two bugs, which were leading to crash/hang under very heavy
network load.

1. Leave the RX interrupt routine if there is no mbuf available.

2. Properly initialize and track tx_desc_used_count counter so as not to
leak mbuf while traversing used descriptors.
