* PS3: gelic: Add support for dual network interfaceMasakazu Mokuno2008-02-111-294/+471
| | | | | | | | | | | | | | | | | | | | | | | | | Add support for dual network (net_device) interface so that ethernet and wireless can own separate ethX interfaces. V2 - Fix the bug that bringing down and up the interface keeps rx disabled. - Make 'gelic_net_poll_controller()' extern , as David Woodhouse pointed out at the previous submission. - Fix weird usage of member names for the rx descriptor chain V1 - Export functions which are convenient for both interfaces - Move irq allocation/release code to driver probe/remove handlers because interfaces share interrupts. - Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb() as the interfaces share the hardware rx queue. - Add gelic_port struct in order to abstract dual interface handling - Change handlers for hardware queues so that they can handle dual {source,destination} interfaces. - Use new NAPI functions This is a prerequisite for the new PS3 wireless support.

* PS3: gelic: code cleanupMasakazu Mokuno2008-02-111-236/+228Star
| | | | | | | | | | | | | | Code cleanup: - Use appropriate prefixes for names instead of fixed 'gelic_net' so that objects of the functions, variables and constants can be estimated. - Remove definitions for IPSec offload to the gelic hardware. This functionality is never supported on PS3. - Group constants with enum. - Use bitwise constants for interrupt status, instead of bit numbers to eliminate shift operations. - Style fixes.

* PS3: changed the way to handle tx skbsMasakazu Mokuno2007-10-111-77/+63Star
| | | | | | | | | | | | | | | | | | | | | 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.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-111-25/+20Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted.

* ps3: fix rare issue that reenabling rx DMA failsMasakazu Mokuno2007-07-241-2/+7
| | | | | | | | | | | | | | Fixed rare issue that 'lv1_net_start_rx_dma failed, status=-9" was shown in dmesg. This meant restarting rx DMA had been rejected by the hypervisor. This issue would caused if the guest os requested starting DMA when the hypervisor thought the DMA was in progress. The state machine for DMA status of the hypervisor would be updated by processing interrupt in the hypervisor. Thus we should wait for the interrupt delivery before restarting DMA.

Hi, This is the third submission of the network driver for PS3. The differences from the previous one are: - renamed source file names so that their prefix can match with the module name - added cbe-oss-dev@ozlabs.org line for MAINTAINER file - changed some in copyright comments If there are no more comments, please apply for 2.6.23. Thank you -- Subject: PS3: Ethernet driver From: Masakazu Mokuno <mokuno@sm.sony.co.jp> Add Gigabit Ethernet support for the PS3 game console. The module will be called ps3_gelic.
