/*
- * Following are the BOOK3S exception handler helper macros.
- * Handlers come in a number of types, and each type has a number of varieties.
- *
- * EXC_REAL_* - real, unrelocated exception vectors
- * EXC_VIRT_* - virt (AIL), unrelocated exception vectors
- * TRAMP_REAL_* - real, unrelocated helpers (virt can call these)
- * TRAMP_VIRT_* - virt, unreloc helpers (in practice, real can use)
- * TRAMP_KVM - KVM handlers that get put into real, unrelocated
- * EXC_COMMON - virt, relocated common handlers
- *
- * The EXC handlers are given a name, and branch to name_common, or the
- * appropriate KVM or masking function. Vector handler verieties are as
- * follows:
- *
- * EXC_{REAL|VIRT}_BEGIN/END - used to open-code the exception
- *
- * EXC_{REAL|VIRT} - standard exception
- *
- * EXC_{REAL|VIRT}_suffix
- * where _suffix is:
- * - _MASKABLE - maskable exception
- * - _OOL - out of line with trampoline to common handler
- * - _HV - HV exception
- *
- * There can be combinations, e.g., EXC_VIRT_OOL_MASKABLE_HV
+ * This is the BOOK3S interrupt entry code macro.
*
- * KVM handlers come in the following verieties:
- * TRAMP_KVM
- * TRAMP_KVM_SKIP
- * TRAMP_KVM_HV
- * TRAMP_KVM_HV_SKIP
- *
- * COMMON handlers come in the following verieties:
- * EXC_COMMON_BEGIN/END - used to open-code the handler
- * EXC_COMMON
- * EXC_COMMON_ASYNC
- *
- * TRAMP_REAL and TRAMP_VIRT can be used with BEGIN/END. KVM
- * and OOL handlers are implemented as types of TRAMP and TRAMP_VIRT handlers.
+ * This can result in one of several things happening:
+ * - Branch to the _common handler, relocated, in virtual mode.
+ * These are normal interrupts (synchronous and asynchronous) handled by
+ * the kernel.
+ * - Branch to KVM, relocated but real mode interrupts remain in real mode.
+ * These occur when HSTATE_IN_GUEST is set. The interrupt may be caused by
+ * / intended for host or guest kernel, but KVM must always be involved
+ * because the machine state is set for guest execution.
+ * - Branch to the masked handler, unrelocated.
+ * These occur when maskable asynchronous interrupts are taken with the
+ * irq_soft_mask set.
+ * - Branch to an "early" handler in real mode but relocated.
+ * This is done if early=1. MCE and HMI use these to handle errors in real
+ * mode.
+ * - Fall through and continue executing in real, unrelocated mode.
+ * This is done if early=2.
