2009-02-09gianfar: Fix boot hangs while bringing up gianfar ethernetJarek Poplawski
Ira Snyder found that commit 8c7396aebb68994c0519e438eecdf4d5fa9c7844 "gianfar: Merge Tx and Rx interrupt for scheduling clean up ring" can cause hangs. It's because there was removed clearing of interrupts in gfar_schedule_cleanup() (which is called by an interrupt handler) in case when netif scheduling has been disabled. This patch brings back this action and a comment.

This causes irq races, so when irqs are enabled and netif_rx_schedule_prep() returns 0, nobody disable the interrupts again. This leads to interrupt storm and finally to the lockup.

This code is based strongly on code from Dai Haruki <Dai.Haruki@freescale.com>. The gianfar Buffer Descriptors are arranged in a circular array, the end of which is denoted by setting the "WRAP" bit in the descriptor. However, the software knows the end of the ring because it knows how many descriptors are there. Rather than check each descriptor for whether the WRAP bit is set, use pointer math to determine where the next BD is. This is also useful for when we want to look at BDs other than the very next one (for Scatter-Gather). Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: David S.

2008-10-31gianfar: Fix race in TBI/SerDes configurationTrent Piepho
The init_phy() function attaches to the PHY, then configures the SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.

2008-10-27net: convert print_mac to %pMJohannes Berg
This converts pretty much everything to print_mac. There were a few things that had conflicts which I have just dropped for now, no harm done. I've built an allyesconfig with this and looked at the files that weren't built very carefully, but it's a huge patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S.
