2007-10-10Device tree aware EMAC driverDavid Gibson
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.

2007-10-10[ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik
For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.

2007-10-10S2io: code Optimization of isr functionSivakumar Subramani
- Code Optimization of s2io_isr function. - Isr check using per device napi variable instead of driver global. - Reduced from 3 to 1 if condition before check for processing packet receive packets. - Implemented Jeff's comment to use synchronize_irq. Removed the isr_cnt variable as it became redundant. - One time de assert the interrupts by writing all F's to the general_int_mask register instead of de asserting by clearing the source of interrupts with multiple writes which causes loss of interrupts (race conditions). It is entirely possible that before the driver has a chance to mask the asserted alarm bit, another alarm/traffic interrupt bit gets asserted as well. In this case Herc will keep the INTA line asserted and the bridge will not send a new Assert_INTA message upstream.

2007-10-10[S2IO]: Handle and monitor all of the device errors and alarmsSivakumar Subramani
- Added support to poll entire set of device errors and alarams. - A note on how device errors and alarms are handled: - The adapter will automatically recover from uncorrectable ECC errors. Packets containing corrupted data will be dropped (not transmitted) or tagged as invalid before being passed to the host. - The adapter cannot recover from any internal state machine errors. A state machine error requires a device reset. - Any internal error that could potentially result in .store trampling. (undesirable PCI behaviour)is tagged as a "serious error". In such cases the adapter will give up its ability to be a bus master. In this situation the host will still be able to read internal device registers in order to generate an error report. A device reset is necessary to return to normal operation. - In the event of a pcix data parity error, the adapter will automatically disable itself. Adapter_En will automatically transition from '1' to '0' and the adapter will enter its clean-up routine. Once the device has achieved quiescence, an adapter reset should be performed. - Replaced alarm_intr_handler() with s2io_handle_errors(). - Added statistic counters to monitor the alarms.

2007-10-10S2io: Enable all the error and alarm indicationsSivakumar Subramani
- Added support to unmask entire set of device errors and alarams. Alarm interrupts are generated for a myriad of purposes, ranging from illegal operations or requests to internal state machine errors and uncorrectable data corruption errors. In several cases the adapter can recover gracefully from unexpected events; however, in some cases, a device reset may be necessary. This patch handles alarms generated by all the blocks within the device. The adapter generates the following types of alarms: 1. Link state transitions (local/remote fault) or other link-related problems. 2. Problems with any device peripherals, including the EEPROM, FLASH, etc. 3. Correctable ECC errors (single-bit errors) on internal data structures or frame data. 4. Uncorrectable ECC errors (multi-bit errors) on internal data structures or frame data. 5. State machine errors, which indicate that internal control structures have become corrupted. 6. PCI related errors, including parity errors or illegal transactions. 7. Other unexpected events. - Implemented Jeff's review comments to use do_s2io_write_bits function to avoid duplicate codes.

2007-10-10PS3: changed the way to handle tx skbsMasakazu Mokuno
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.

2007-10-10pasemi_mac: Clean TX ring in pollOlof Johansson
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.
