2011-07-14net/ps3: Fix gelic RX DMA restartGeoff Levand
Fix the condition where PS3 network RX hangs when no network TX is occurring by calling gelic_card_enable_rxdmac() during RX_DMA_CHAIN_END event processing. The gelic hardware automatically clears its RX_DMA_EN flag when it detects an RX_DMA_CHAIN_END event. In its processing of RX_DMA_CHAIN_END the gelic driver is required to set RX_DMA_EN (with a call to gelic_card_enable_rxdmac()) to restart RX DMA transfers. The existing gelic driver code does not set RX_DMA_EN directly in its processing of the RX_DMA_CHAIN_END event, but uses a flag variable card->rx_dma_restart_required to schedule the setting of RX_DMA_EN until next inside the interrupt handler. It seems this delayed setting of RX_DMA_EN causes the hang since the next RX interrupt after the RX_DMA_CHAIN_END event where RX_DMA_EN is scheduled to be set will not occur since RX_DMA_EN was not set. In the case were network TX is occuring, RX_DMA_EN is set in the next TX interrupt and RX processing continues. Signed-off-by: Geoff Levand <geoff@infradead.org> Signed-off-by: David S.

2009-12-02net/ps3: Cleanup gelic enumsGeoff Levand
Cleanup of the gelic driver enumerations: o Add some missing commas. o Add an Ether port post fix (PS3 currently only supports PORT_0). o Add a new enum gelic_lv1_phy to use when interacting with the PHY.

2008-02-11PS3: gelic: Add support for dual network interfaceMasakazu Mokuno
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.

2008-02-11PS3: gelic: code cleanupMasakazu Mokuno
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.

2007-10-10[NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger
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. Integrated Stephen's follow-on kerneldoc additions, and restored poll_list handling to the old style to fix mutual exclusion issues. -DaveM ] Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.

2007-07-24ps3: fix rare issue that reenabling rx DMA failsMasakazu Mokuno
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.
