* ia64: iosapic: Use new irq_move_* functionsThomas Gleixner2011-03-291-6/+4
| | | | | | | | | The current functions are going away. Also use the accessor for pending setaffinity in irq_data instead of the open coded irq_desc access. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* ia64: iosapic: Remove redundant mask from ack()Thomas Gleixner2011-03-291-9/+0
| | | | | | | | The core code calls mask_ack() which calls irq_ack() and irq_mask() for the case where an interrupt is disabled and marked pending. That seems to be a leftover from the old __do_IRQ() mode. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| * | [IA64] Initialize interrupts later (from init_IRQ())Tony Luck2010-10-051-47/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | Thomas Gleixner is cleaning up the generic irq code, and ia64 ran into problems because it calls register_intr() before early_irq_init() is called. Move the call to acpi_boot_init() from setup_arch() to init_IRQ(). As a bonus - moving the call later means we no longer need the hacks in iosapic.c to switch between the bootmem and regular allocator - we can just used kzalloc() for allocation.

Since then another 18 months have gone by ... Mostly trivial stuff for this. The only tricky part was realizing that the new handler_*_irq() paths do not use desc->chip->end(irq). Not a problem for the edge case as the ia64 iosapic routine for that was nop(). But the "level" case handled interrupt migration there. Just use a slightly modified version of the "end" routine as "unmask" for the level triggered case. Signed-off-by: Tony Luck <tony.luck@intel.com>
* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* [IA64] Fix irq migration in multiple vector domainKenji Kaneshige2008-03-041-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the problem that the following error message is sometimes displayed at irq migration when vector domain is enabled. "Unexpected interrupt vector %d on CPU %d is not mapped to any IRQ!" The cause of this problem is an interrupt is sent to the previous target CPU after cleaning up vector to irq mapping table. To clean up vector to irq map on the previous target CPU safty, change the irq migration in multiple vector domain as follows. The original idea is from x86 interrupt management code. - Delay vector to irq table cleanup until the interrupts are sent to new target CPUs. By this, it is ensured that target CPU is completely changed on the interrupt controller side. - Even after the interrupts are sent to new target CPUs, there can be pended interrupts remaining on the previous target CPU. So we need to delay clearning up vector to irq table until the pended interrupt is handled. For this, send IPI to the previous target CPU with lower priority vector and clean up vector to irq table in its handler. This patch affects only to irq migration code with multiple vector domain is enabled. Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

This is necessary for supporting multiple vector domain because 1:1 mapping between irq and vector will be changed to n:1. The irq == vector relationship between irqs and vectors is explicitly remained for percpu interrupts, platform interrupts, isa IRQs and vectors assigned using assign_irq_vector() because some programs might depend on it. And I should consider the following problem. When pci drivers enabled/disabled devices dynamically, its irq number is changed to the different one. Therefore, suspend/resume code may happen problem.

* [IA64] fix NULL pointer in ia64/irq_chip-mask/unmask functionKAMEZAWA Hiroyuki2007-03-071-2/+6
| | | | | | | | | | | | | This patch fixes boot failure because irq_desc->mask() is NULL. - Added mask/unmask functions to ia64's irq desc function table. - rename hw_interrupt_type to irq_chip. hw_interrupt_type is old name. - Tony: Added same change to arch/ia64/sn/kernel/irq.c as pointed out by Eric Biederman ... mask/unmask functions there can be no-op.

* [IA64] Clear IRQ affinity when unregisteredAlex Williamson2007-02-051-0/+5
| | | | | | | | | | | | | | | | | | | | When we offline a CPU, migrate_irqs() tries to determine whether the affinity bits of the IRQ descriptor match any of the remaining online CPUs. If not, it fixes up the interrupt to point somewhere else. Unfortunately, if an IRQ is unregistered the IRQ descriptor may still have affinity to the CPU being offlined, but the no_irq_chip handler doesn't provide a set_affinity function. This causes us to hit the WARN_ON in migrate_irqs(). The easiest solution seems to be setting all the bits in the affinity mask when the last interrupt is removed from the vector. I hit this on an older kernel with Xen/ia64 using driver domains (so it probably needs more testing on upstream). Xen essentially uses the bind/unbind interface in sysfs to unregister a device from a driver and thus unregister the interrupt.
