2010-02-17powerpc: Remove whitespace in irq chip name fieldsAnton Blanchard1-1/+1
Now we use printf style alignment there is no need to manually space these fields. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-11-24powerpc: Fixup last users of irq_chip->typenameThomas Gleixner1-1/+1
The typename member of struct irq_chip was kept for migration purposes and is obsolete since more than 2 years. Fix up the leftovers.

2008-08-20powerpc: Convert the MPIC MSI code to use msi_bitmapMichael Ellerman1-11/+13
This affects the U3 MSI code as well as the PASEMI MSI code. We keep some of the MPIC routines as helpers, and also the U3 best-guess reservation logic. The rest is replaced by the generic code. And a few printk format changes due to hwirq type change. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-05-14[POWERPC] mpic_pasemi_msi: Failed allocation unnoticedRoel Kluin1-2/+4
bitmap_find_free_region(), called by mpic_msi_alloc_hwirqs() may return signed, but hwirq is unsigned. A failed allocation remains unnoticed. Signed-off-by: Roel Kluin <12o3l@tiscali.nl> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-02-21[POWERPC] pasemi: Remove warning in mpic_pasemi_msi.cOlof Johansson1-3/+2
Remove warning: arch/powerpc/sysdev/mpic_pasemi_msi.c: In function 'pasemi_msi_setup_msi_irqs': arch/powerpc/sysdev/mpic_pasemi_msi.c:135: warning: 'addr' is used uninitialized in this function Turns out addr wasn't even used, it's a leftover from the u3msi code.

2007-12-20[POWERPC] pasemi: Implement MSI supportOlof Johansson1-0/+172
Implement MSI support for PA Semi PWRficient platforms. MSI is done through a special range of sources on the openpic controller, and they're unfortunately breaking the usual concepts of how sources are programmed: * The source is calculated as 512 + the value written into the MSI register * The vector for this source is added to the source and reported through IACK This means that for simplicity, it makes much more sense to just set the vector to 0 for the source, since that's really the vector we expect to see from IACK. Also, the affinity/priority registers will affect 16 sources at a time. To avoid most (simple) users from being limited by this, allocate 16 sources per device but use only one. This means that there's a total of 32 sources. If we get usage scenarions that need more sources, the allocator should probably be revised to take an alignment argument and size, not just do natural alignment. Finally, since I'm already touching the MPIC names on pasemi, rename the base one from the somewhat odd " PAS-OPIC " to "PASEMI-OPIC".
