|

* 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
|
||||
*
|
||||
* The one unusual case is __EXC_REAL_OOL_HV_DIRECT, which is
|
||||
* an OOL vector that branches to a specified handler rather than the usual
|
||||
* trampoline that goes to common. It, and other underscore macros, should
|
||||
* be used with care.
|
||||
*
|
||||
* 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.
