[TC] TURBOchannel support for the DECstation

2007-02-09T16:23:16Z

This is the platform-specific part of TURBOchannel bus support for the DECstation. It implements determining whether the bus is actually there, getting bus parameters, IRQ assignments for devices and protected accesses to possibly unoccupied slots that may trigger bus error exceptions.

[TC] MIPS: TURBOchannel update to the driver model

2007-02-09T16:23:15Z

This is a set of changes to convert support for the TURBOchannel bus to the driver model. It implements the usual set of calls similar to what other bus drivers have: tc_register_driver(), tc_unregister_driver(), etc. All the platform-specific bits have been removed and headers from asm-mips/dec/ have been merged into linux/tc.h, which should be included by drivers.

[MIPS] Define MIPS_CPU_IRQ_BASE in generic header

2007-02-06T16:53:08Z

The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all platforms and are same value on most platforms (0 or 16, depends on CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make them customizable. This will save a few cycle on each CPU interrupt. A good side effect is removing some dependencies to MALTA in generic SMTC code. Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing them might cause some header dependency problem and there seems no good reason to customize it. So currently only VR41XX is using custom MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259. Testing this patch on those platforms is greatly appreciated. Thank you.

[MIPS] IRQ cleanups

2006-11-30T01:14:46Z

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. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

System-specific handling of bus errors for DECstation variations
