[PATCH 7/7] xen/events: remove some info_for_irq() calls in pirq handling

Instead of the IRQ number user the struct irq_info pointer as parameter in the internal pirq related functions. This allows to drop some calls of info_for_irq(). Signed-off-by: Juergen Gross --- drivers/xen/events/events_base.c | 113 +++ 1 file changed, 68 insertions

[PATCH 6/7] xen/events: modify internal [un]bind interfaces

Modify the internal bind- and unbind-interfaces to take a struct irq_info parameter. When allocating a new IRQ pass the pointer from the allocating function further up. This will reduce the number of info_for_irq() calls and make the code more efficient. Signed-off-by: Juergen Gross --- drivers

[PATCH 4/7] xen/events: remove some simple helpers from events_base.c

The helper functions type_from_irq() and cpu_from_irq() are just one line functions used only internally. Open code them where needed. At the same time modify and rename get_evtchn_to_irq() to return a struct irq_info instead of the IRQ number. Signed-off-by: Juergen Gross --- drivers/xen/event

[PATCH 5/7] xen/events: drop xen_allocate_irqs_dynamic()

Instead of having a common function for allocating a single IRQ or a consecutive number of IRQs, split up the functionality into the callers of xen_allocate_irqs_dynamic(). This allows to handle any allocation error in xen_irq_init() gracefully instead of panicing the system. Let xen_irq_init() re

[PATCH 2/7] xen/events: remove unused functions

There are no users of xen_irq_from_pirq() and xen_set_irq_pending(). Remove those functions. Signed-off-by: Juergen Gross --- drivers/xen/events/events_base.c | 30 -- include/xen/events.h | 4 2 files changed, 34 deletions(-) diff --git a/drivers/

[PATCH 0/7] xen/events: do some cleanups in events_base.c

As a followup to the XSA-441 patch this series is doing a minor bug fix and some cleanups of events_base.c (with some minor effects outside of it). Juergen Gross (7): xen/events: fix delayed eoi list handling xen/events: remove unused functions xen/events: reduce externally visible helper fu

[PATCH 3/7] xen/events: reduce externally visible helper functions

get_evtchn_to_irq() has only one external user while irq_from_evtchn() provides the same functionality and is exported for a wider user base. Modify the only external user of get_evtchn_to_irq() to use irq_from_evtchn() instead and make get_evtchn_to_irq() static. evtchn_from_irq() and irq_from_vi

[PATCH 1/7] xen/events: fix delayed eoi list handling

When delaying eoi handling of events, the related elements are queued into the percpu lateeoi list. In case the list isn't empty, the elements should be sorted by the time when eoi handling is to happen. Unfortunately a new element will never be queued at the start of the list, even if it has a ha
