2006-12-09[MIPS] Add GENERIC_HARDIRQS_NO__DO_IRQ for i8259 usersAtsushi Nemoto
Now that i8259A_chip uses new irq flow handler select GENERIC_HARDIRQS_NO__DO_IRQ on some more platforms. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-12-06[MIPS] Compile __do_IRQ() when really neededFranck Bui-Huu
__do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.

2006-11-30[MIPS] use generic_handle_irq, handle_level_irq, handle_percpu_irqAtsushi Nemoto
Further incorporation of generic irq framework. Replacing __do_IRQ() by proper flow handler would make the irq handling path a bit simpler and faster. * use generic_handle_irq() instead of __do_IRQ(). * use handle_level_irq for obvious level-type irq chips. * use handle_percpu_irq for irqs marked as IRQ_PER_CPU. * setup .eoi routine for irq chips possibly used with handle_percpu_irq.

2006-11-30[MIPS] IRQ cleanupsAtsushi Nemoto
This is a big irq cleanup patch. * Use set_irq_chip() to register irq_chip. * Initialize .mask, .unmask, .mask_ack field. Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks.

2006-06-29[PATCH] genirq: rename desc->handler to desc->chipIngo Molnar
This patch-queue improves the generic IRQ layer to be truly generic, by adding various abstractions and features to it, without impacting existing functionality. While the queue can be best described as "fix and improve everything in the generic IRQ layer that we could think of", and thus it consists of many smaller features and lots of cleanups, the one feature that stands out most is the new 'irq chip' abstraction. The irq-chip abstraction is about describing and coding and IRQ controller driver by mapping its raw hardware capabilities [and quirks, if needed] in a straightforward way, without having to think about "IRQ flow" (level/edge/etc.) type of details. This stands in contrast with the current 'irq-type' model of genirq architectures, which 'mixes' raw hardware capabilities with 'flow' details. The patchset supports both types of irq controller designs at once, and converts i386 and x86_64 to the new irq-chip design. As a bonus side-effect of the irq-chip approach, chained interrupt controllers (master/slave PIC constructs, etc.) are now supported by design as well. The end result of this patchset intends to be simpler architecture-level code and more consolidation between architectures. We reused many bits of code and many concepts from Russell King's ARM IRQ layer, the merging of which was one of the motivations for this patchset. This patch: rename desc->handler to desc->chip. Originally i did not want to do this, because it's a big patch. But having both "desc->handler", "desc->handle_irq" and "action->handler" caused a large degree of confusion and made the code appear alot less clean than it truly is. I have also attempted a dual approach as well by introducing a desc->chip alias - but that just wasnt robust enough and broke frequently. So lets get over with this quickly. The conversion was done automatically via scripts and converts all the code in the kernel. This renaming patch is the first one amongst the patches, so that the remaining patches can stay flexible and can be merged and split up without having some big monolithic patch act as a merge barrier.

2006-06-19[MIPS] Cleanup memory managment initialization.Ralf Baechle
Historically plat_mem_setup did the entire platform initialization. This was rather impractical because it meant plat_mem_setup had to get away without any kind of memory allocator. To keep old code from breaking plat_setup was just renamed to plat_setup and a second platform initialization hook for anything else was introduced. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-04-19[MIPS] Rewrite all the assembler interrupt handlers to C.Ralf Baechle
Saves like 1,600 lines of code, is way easier to debug, compilers frequently do a better job than the cut and paste type of handlers many boards had. And finally having all the stuff done in a single place also means alot of bug potencial for the MT ASE is gone. The only surviving handler in assembler is the DECstation one; I hope Maciej will rewrite it. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-02-07[MIPS] TX49x7: Fix reporting of the CPU name and PCI clockSergei Shtylylov
I've noticed that PCI clock was incorrectly reported as 66 MHz while being mere 33 MHz on RBTX4937 board -- this was due to the different encoding of the PCI divisor field in CCFG register between TX4927 and TX4937 chips... Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937"); and some debug printk() were duplicating each other...

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
