Subject: [PATCH 00/28 v6] m68k: Convert to genirq
This patch series converts the m68k/mmu (nommu was converted before)
architecture to the generic hardirq framework.
- [01/28] genirq: Add missing "else" in irq_shutdown()
- [02/28] ide-{cd,floppy,tape}: Do not include <linux/irq.>
- [03/28] keyboard: Do not include <linux/irq.>
- [04/28] m68k/irq: Rename irq_controller to irq_chip
- [05/28] m68k/irq: Kill irq_node_t typedef, always use struct irq_node
- [06/28] m68k/irq: Rename irq_node to irq_data
- [07/28] m68k/irq: Switch irq_chip methods to "struct irq_data *data"
- [08/28] m68k/irq: Rename setup_irq() to m68k_setup_irq() and make it static
- [09/28] m68k/irq: Extract irq_set_chip()
- [10/28] m68k/irq: Add m68k_setup_irq_controller()
- [11/28] m68k/irq: Rename {,__}m68k_handle_int()
- [12/28] m68k/irq: Remove obsolete IRQ_FLG_* definitions and users
- [13/28] m68k/irq: Add genirq support
- [14/28] m68k/atari: Convert Atari to genirq
- [15/28] m68k/atari: Remove code and comments about different irq types
- [16/28] m68k/amiga: Refactor amiints.c
- [17/28] m68k/amiga: Convert Amiga to genirq
- [18/28] m68k/amiga: Optimize interrupts using chain handlers
- [19/28] m68k/mac: Convert Mac to genirq
- [20/28] m68k/mac: Optimize interrupts using chain handlers
- [21/28] m68k/hp300: Convert HP9000/300 and HP9000/400 to genirq
- [22/28] m68k/vme: Convert VME to genirq
- [23/28] m68k/apollo: Convert Apollo to genirq
- [24/28] m68k/sun3: Use the kstat_irqs_cpu() wrapper
- [25/28] m68k/sun3: Convert Sun3/3x to genirq
- [26/28] m68k/q40: Convert Q40/Q60 to genirq
- [27/28] m68k/irq: Remove obsolete m68k irq framework
- [28/28] m68k/irq: Remove obsolete support for user vector interrupt fixups
Overview:
- [01] is a fix for the core genirq code,
- [02-03] are fixes to avoid compile problems later in the conversion
process,
- [04-12] refactor the current m68k irq framework to match the generic
hardirq framework more closely w.r.t. to its (platform) users,
- [13] adds generic hardirq support to the core, which can be enabled through
a config option, so both legacy and generic hardirq can coexist at the
source level during the migration,
- [14-26] convert the individual platforms to use generic hardirqs,
- [27] removes support for the legacy m68k irq framework,
- [28] removes a now unused feature.
The code has received some testing on Amiga, Atari (mainly ARAnyM), and Mac.
There are some known issues with drivers, which Finn and Michael are looking
into.
I will update my m68k-genirq branch as soon as master.kernel.org is available
again.
Thanks for your comments, feedback, and testing!
Changelog:
v6:
- Add [01] genirq: Add missing "else" in irq_shutdown()
- Add [27] m68k/irq: Remove obsolete m68k irq framework
- Add [28] m68k/irq: Remove obsolete support for user vector interrupt
fixups
- Split off [02] ide-{cd,floppy,tape}: Do not include <linux/irq.>
- Split off [03] keyboard: Do not include <linux/irq.>
- Keep irq_canonicalize(), which is needed for ac3200, atari_91C111,
serial_core, and 8250.
- Correct irq args of irq_set_handler_data() calls in Mac PSC chain
handlers, as reported by Finn
v5:
- Add [20] m68k/mac: Optimize interrupts using chain handlers
- Add [26] m68k/q40: Convert Q40/Q60 to genirq
- Keep m68k_setup_auto_interrupt(), it's still needed for Q40
v4:
- Add [15] m68k/atari: Remove code and comments about different irq
types
- Add [23] m68k/apollo: Convert Apollo to genirq
- Add [24] m68k/sun3: Use the kstat_irqs_cpu() wrapper
- Add [25] m68k/sun3: Convert Sun3/3x to genirq
v3:
- Add [11] m68k/irq: Rename {,__}m68k_handle_int()
- Add [12] m68k/irq: Remove obsolete IRQ_FLG_* definitions and users
- Add [19] m68k/mac: Convert Mac to genirq
- Add [21] m68k/hp300: Convert HP9000/300 and HP9000/400 to genirq
- Add [22] m68k/vme: Convert VME to genirq
- Use handle_simple_irq() instead of handle_level_irq(), which also
means we don't need the .irq_{,un}mask methods anymore, so they can
be removed again.
- Wrapper __m68k_handle_int() for do_IRQ() is no longer needed
- Keep track of spurious interrupts
v2:
- Add [10] m68k/irq: Add m68k_setup_irq_controller()
- Add [16] m68k/amiga: Refactor amiints.c
- Add [17] m68k/amiga: Convert Amiga to genirq
- Add [18] m68k/amiga: Optimize interrupts using chain handlers]
- Add missing "irq" offset in m68k_setup_irq_controller()
- Set up default handlers for autovector interrupts, and fill in missing
.irq_{,un}mask methods,
v1:
