Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

[PATCH] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now.

[PATCH] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers 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] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers 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] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers 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.

This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

[PATCH] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

[PATCH] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream.

ibm_emac: Convert to use napi_struct independent of struct net_device Commit da3dedd9 ("[NET]: Make NAPI polling independent of struct net_device objects.") changed the interface to NAPI polling. Fix up the ibm_emac driver so that it works with this new interface. This is actually a nice cleanup because ibm_emac is one of the drivers that wants to have multiple NAPI structures for a single net_device.

This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

ibm_emac: Convert to use napi_struct independent of struct net_device Commit da3dedd9 ("[NET]: Make NAPI polling independent of struct net_device objects.") changed the interface to NAPI polling. Fix up the ibm_emac driver so that it works with this new interface. This is actually a nice cleanup because ibm_emac is one of the drivers that wants to have multiple NAPI structures for a single net_device. Tested with the internal MAC of a PowerPC 440SPe SoC with an AMCC 'Yucca' evaluation board. Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

[PATCH] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream.
