2007-02-10[SPARC64]: Add PCI MSI support on Niagara.David S. Miller
This is kind of hokey, we could use the hardware provided facilities much better. MSIs are assosciated with MSI Queues. MSI Queues generate interrupts when any MSI assosciated with it is signalled. This suggests a two-tiered IRQ dispatch scheme: MSI Queue interrupt --> queue interrupt handler MSI dispatch --> driver interrupt handler But we just get one-level under Linux currently. What I'd like to do is possibly stick the IRQ actions into a per-MSI-Queue data structure, and dispatch them form there, but the generic IRQ layer doesn't provide a way to do that right now. So, the current kludge is to "ACK" the interrupt by processing the MSI Queue data structures and ACK'ing them, then we run the actual handler like normal. We are wasting a lot of useful information, for example the MSI data and address are provided with ever MSI, as well as a system tick if available. If we could pass this into the IRQ handler it could help with certain things, in particular for PCI-Express error messages. The MSI entries on sparc64 also tell you exactly which bus/device/fn sent the MSI, which would be great for error handling when no registered IRQ handler can service the interrupt. We override the disable/enable IRQ chip methods in sun4v_msi, so we have to call {mask,unmask}_msi_irq() directly from there. This is another ugly wart. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-02-10[SPARC64] IRQ: Use irq_desc->chip_data instead of irq_desc->handler_dataDavid S. Miller
Otherwise we can't use the generic MSI code. Furthermore, properly use the {get,set}_irq_foo() abstracted interfaces instead of direct accesses to irq_desc[]->foo. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-02-09[AVR32] Add PIOE device and reserve SDRAM pinsHaavard Skinnemoen
The PIOE device was left out before because it muxes SDRAM pins (and is therefore a bit dangerous to mess with) and because no existing drivers had any use for it. It is needed for CompactFlash, however, and now that we have a way to protect the SDRAM pins, it can be safely added. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2007-02-09[AVR32] ext int fixesDavid Brownell
Bugfixes for external irq handler set_irq_type(): - If set_irq_type() can't set the type, don't change anything! - It's not OK to change the flow handler as part of set_irq_type(), among other issues that violates spinlock rules. Instead, we can call the relevant handler when we demux the external interrupts. - The external irq demux has no need to grab the spinlock. And in fact grabbing it that way was wrong, since that code might be pre-empted by an irq at a different priority level, and that code might then have tried to grab that spinlock...
