2007-01-18Update ucc_geth.c for new workqueue structureTimur Tabi
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>

2006-10-21[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes ↵Li Yang
and bugfixes changes due to qe_lib changes include: o removed inclusion of platform header file o removed platform_device code, replaced with of_device o removed typedefs o uint -> u32 conversions o removed following defines: QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER, BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET because they hid sizeof/in_be32/out_be32 operations from the reader. o removed irrelevant comments, added others to resemble removed BD_ defines o const'd and uncasted all get_property() assignments bugfixes, courtesy of Scott Wood, include: - Read phy_address as a u32, not u8. - Match on type == "network" as well as compatible == "ucc_geth", as device_is_compatible() will only compare up to the length of the test string, allowing "ucc_geth_phy" to match as well. - fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2006-09-12[PATCH] Remove more unnecessary driver printk'sAndy Gospodarek
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>
2006-08-19[PATCH] Freescale QE UCC gigabit ethernet driverLi Yang
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.
