Raw Normal View History

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!

/*
Theory of Operation
I. Board Compatibility
This device driver is designed for the 3Com 3c574 PC card Fast Ethernet
Adapter.
II. Board-specific settings
None -- PC cards are autoconfigured.
III. Driver operation
The 3c574 uses a Boomerang-style interface, without the bus-master capability.
See the Boomerang driver and documentation for most details.
IV. Notes and chip documentation.
Two added registers are used to enhance PIO performance, RunnerRdCtrl and
RunnerWrCtrl. These are 11 bit down-counters that are preloaded with the
count of word (16 bits) reads or writes the driver is about to do to the Rx
or Tx FIFO. The chip is then able to hide the internal-PCI-bus to PC-card
translation latency by buffering the I/O operations with an 8 word FIFO.
Note: No other chip accesses are permitted when this buffer is used.
A second enhancement is that both attribute and common memory space
0x0800-0x0fff can translated to the PIO FIFO. Thus memory operations (faster
with *some* PCcard bridges) may be used instead of I/O operations.
This is enabled by setting the 0x10 bit in the PCMCIA LAN COR.
Some slow PC card bridges work better if they never see a WAIT signal.
This is configured by setting the 0x20 bit in the PCMCIA LAN COR.
Only do this after testing that it is reliable and improves performance.
The upper five bits of RunnerRdCtrl are used to window into PCcard
configuration space registers. Window 0 is the regular Boomerang/Odie
register set, 1-5 are various PC card control registers, and 16-31 are
the (reversed!) CIS table.
A final note: writing the InternalConfig register in window 3 with an
invalid ramWidth is Very Bad.

3c574, 3c515 bitfields abuse wn3_config is shared by these cards; the way we deal with it is both bad C (union abuse) and broken on big-endian. For 3c515 it's less serious (ISA cards are quite rare outside of little-endian boxen), but 3c574 is a pcmcia one and that'd better be endian-independent... Fix is the same in both cases.

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.

3c574, 3c515 bitfields abuse wn3_config is shared by these cards; the way we deal with it is both bad C (union abuse) and broken on big-endian. For 3c515 it's less serious (ISA cards are quite rare outside of little-endian boxen), but 3c574 is a pcmcia one and that'd better be endian-independent... Fix is the same in both cases.

/* The EL3 interrupt handler. */
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.
