From 35b61d5f465d085a69772e5c769fc1a38984dd97 Mon Sep 17 00:00:00 2001 From: Leonid Komarianskyi Date: Tue, 9 Sep 2025 10:09:23 +0000 Subject: [PATCH] xen/arm: gicv3: modify ICH_LR_PHYSICAL_MASK to allow eSPI processing To properly deactivate physical eSPI routed to a domain and allow them to be retriggered after the initial trigger, the LR needs to be updated. The current implementation ignores interrupts outside the range specified by the mask 0x3FF, which only covers IRQ numbers up to 1023. To enable processing of eSPI interrupts, this patch updates the mask to 0x1FFF.
