* ucc_geth: fixes for ucc_geth_memcleanNicu Ioan Petru2007-04-281-7/+6
| | | | | | | | | | | | | | | | | | The ucc_geth_memclean function can be called before the Tx BD rings, Rx BD rings and associated socket buffers are allocated (for example if ucc_fast_init fails). The current code doesn't check if p_tx_bd_ring[i] is null, generating a kernel panic when trying to free the associated socket buffers. The function can also fail when accessing the uninitialized list_head structures ugeth->group_hash_q and ugeth->ind_hash_q. In the current implementation the list heads are initialized only when maxGroupAddrInHash and maxIndAddrInHash are positive values, although I think it's better to always initialize them.

* ucc_geth: NAPI-related bug fixesMichael Reiss2007-04-281-40/+58
| | | | | | | | | | | | | | | | | | | | | | Based partly on the gianfar driver, this patch fixes several bugs which were causing NAPI to be completely unusable. * An IRQ is still needed in NAPI, to kick off NAPI task, and for Tx processing. Request the IRQ. * If rx_work_limit = 0 we are not complete. * While running Rx NAPI processing we must mask Rx events, including Rx busy. * ucc_geth_rx function does not need a lock. Could lead to deadlock in NAPI case. * There's no need to loop reading ucce multiple times in the ISR, so while adding the call to schedule NAPI which was not there, simplify the event processing into if-else format. * Rx Busy now kicks off NAPI processing, while still being counted as an error.

* ucc_geth: migrate ucc_geth to phylibKim Phillips2007-04-281-543/+271
| | | | | | | | | | | | | | | | | | | | | | | | | | | | migrate ucc_geth to use the common phylib code. There are several side effects from doing this: o deprecate 'interface' property specification present in some old device tree source files in favour of a split 'max-speed' and 'interface-type' description to appropriately match definitions in include/linux/phy.h. Note that 'interface' property is still honoured if max-speed or interface-type are not present (backward compatible). o compile-time CONFIG_UGETH_HAS_GIGA is eliminated in favour of probe time speed derivation logic. o adjust_link streamlined to only operate on maccfg2 and upsmr.r10m, instead of reapplying static initial values related to the interface-type. o Addition of UEC MDIO of_platform driver requires platform code add 'mdio' type to id list prior to calling of_platform_bus_probe (separate patch). o ucc_struct_init introduced to reduce ucc_geth_startup complexity.

* Revert "ucc_geth: returns NETDEV_TX_BUSY when BD ring is full"Li Yang2007-03-231-2/+1
| | | | | | | | | | | | | | This reverts commit 18babd38547a042a4bfd4154a014d1ad33373eb0. Michael Barkowski points out that it's wrong, and I agree. The patch causes a problem rather than fixes one after another patch "ucc_geth: Fix BD processing" was applied. Before that patch, current packet should be blocked. However after the patch current packet is ok and we only need to block next.

* Update ucc_geth.c for new workqueue structureTimur Tabi2007-01-181-5/+7
| | | | | | | | | | | | | | The workqueue interface changed with David Howell's patch on 11/22/2006 (SHA 65f27f38446e1976cc98fd3004b110fedcddd189). Several drivers were updated with that patch to handle the new interface, but ucc_geth.c was not one of them. This patch updates ucc_geth.c to support the new model. A compiler warning in set_mac_addr() was also fixed. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

* [PATCH] Remove more unnecessary driver printk'sAndy Gospodarek2006-09-121-3/+1
| | | | | | | | | | | | | | As I promised last week, here is the first pass at removing all unnecessary printk's that exist in network device drivers currently in promiscuous mode. The duplicate messages are not needed so they have been removed. Some of these drivers are quite old and might not need an update, but I did them all anyway. I am currently auditing the remaining conditional printk's and will send out a patch for those soon. Signed-off-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] Freescale QE UCC gigabit ethernet driverLi Yang2006-08-191-0/+4278
QE(QUICC Engine) is a new generation communication coprocessor, which can be found on some of the latest Freescale PowerQUICC CPUs(e.g. MPC8360). The UCC(Unified Communications Controller) module of QE can work as gigabit Ethernet device. This patch provides driver for the device.
