After that re-factoring, when pirq<0 and current_pirq>0, it means -caller want to allocate a free pirq for irq but irq already has a mapped pirq, then -it returns the negative pirq, so it fails. However, the logic before that -re-factoring is different, it should return the current_pirq that irq was already -mapped to and make the call success. - -Fixes: 0762e2502f1f ("x86/physdev: factor out the code to allocate and map a pirq") -Signed-off-by: Jiqian Chen <Jiqian.Chen@amd.com> -Signed-off-by: Huang Rui <ray.huang@amd.com> -Signed-off-by: Jiqian Chen <Jiqian.Chen@amd.com> -Reviewed-by: Jan Beulich <jbeulich@suse.com> -master commit: 0d2b87b5adfc19e87e9027d996db204c66a47f30 -master date: 2024-07-08 14:46:12 +0100 ---- - xen/arch/x86/irq.c | 1 + - 1 file changed, 1 insertion(+) - -diff --git a/xen/arch/x86/irq.c b/xen/arch/x86/irq.c -index 5dae8bd1b9..6b1f338eae 100644 ---- a/xen/arch/x86/irq.c -+++ b/xen/arch/x86/irq.c -@@ -2914,6 +2914,7 @@ static int allocate_pirq(struct domain *d, int index, int pirq, int irq, - d->domain_id, index, pirq, current_pirq); - if ( current_pirq < 0 ) - return -EBUSY; -+ pirq = current_pirq; - } - else if ( type == MAP_PIRQ_TYPE_MULTI_MSI ) - { --- -2.45.2 - |
