[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH V5 12/22] xen/ioreq: Remove "hvm" prefixes from involved function names
From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>
This patch removes "hvm" prefixes and infixes from IOREQ related
function names in the common code and performs a renaming where
appropriate according to the more consistent new naming scheme:
- IOREQ server functions should start with "ioreq_server_"
- IOREQ functions should start with "ioreq_"
A few function names are clarified to better fit into their purposes:
handle_hvm_io_completion -> vcpu_ioreq_handle_completion
hvm_io_pending -> vcpu_ioreq_pending
hvm_ioreq_init -> ioreq_domain_init
hvm_alloc_ioreq_mfn -> ioreq_server_alloc_mfn
hvm_free_ioreq_mfn -> ioreq_server_free_mfn

Please note, this is a split/cleanup/hardening of Julien's PoC:
"Add support for Guest IO forwarding to a device emulator"
Changes V1 -> V2:
- new patch
Changes V2 -> V3:
- update patch according the "legacy interface" is x86 specific
- update patch description
- rename everything touched according to new naming scheme
Changes V3 -> V4:
- rebase
- rename ioreq_update_evtchn() to ioreq_server_update_evtchn()
- add Jan's R-b
Changes V4 -> V5:
- rebase
- add Paul's R-b
