x86/htirq: Use hierarchical irqdomain to manage Hypertransport interrupts

2015-04-24T13:36:50+00:00

We have slightly changed the architecture interfaces to support htirq
PCI driver. It's safe because currently Hypertransport interrupt is
only enabled on x86 platforms.

x86/htirq: Use new irqdomain interfaces to allocate/free IRQ

2015-04-24T13:36:48+00:00

Use new irqdomain interfaces to allocate/free IRQ for HTIRQ, so we can
remove GENERIC_IRQ_LEGACY_ALLOC_HWIRQ later.

This patch changes the interfaces between arch independent PCI driver
and arch specific code. Currently HT_IRQ is only enabled on x86, so it
does not affect other architectures.

[PATCH] htirq: allow buggy drivers of buggy hardware to write the registers

2006-11-09T02:29:25+00:00

This patch adds a variant of ht_create_irq __ht_create_irq that takes an
aditional parameter update that is a function that is called whenever we want
to write to a drivers htirq configuration registers.

This is needed to support the ipath_iba6110 because it's registers in the
proper location are not actually conected to the hardware that controlls
interrupt delivery.

[PATCH] htirq: refactor so we only have one function that writes to the chip

2006-11-09T02:29:24+00:00

This refactoring actually optimizes the code a little by caching the value
that we think the device is programmed with instead of reading it back from
the hardware.  Which simplifies the code a little and should speed things up a
bit.

This patch introduces the concept of a ht_irq_msg and modifies the
architecture read/write routines to update this code.

There is a minor consistency fix here as well as x86_64 forgot to initialize
the htirq as masked.

[PATCH] htirq: tidy up the htirq code

2006-10-04T14:55:30+00:00

This moves the declarations for the architecture helpers into
include/linux/htirq.h from the generic include/linux/pci.h.  Hopefully this
will make this distinction clearer.

htirq.h is included where it is needed.

The dependency on the msi code is fixed and removed.

The Makefile is tidied up.
