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 Signed-off-by: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx> Reviewed-by: Jan Beulich <jbeulich@xxxxxxxx> Reviewed-by: Paul Durrant <paul@xxxxxxx> CC: Julien Grall <julien.grall@xxxxxxx> [On Arm only] Tested-by: Wei Chen <Wei.Chen@xxxxxxx> --- 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 Changes V5 -> V6: - no changes --- --- xen/arch/x86/hvm/emulate.c | 6 +- xen/arch/x86/hvm/hvm.c | 10 ++-- xen/arch/x86/hvm/io.c | 6 +- xen/arch/x86/hvm/ioreq.c | 2 +- xen/arch/x86/hvm/stdvga.c | 4 +- xen/arch/x86/hvm/vmx/vvmx.c | 2 +- xen/common/ioreq.c | 138 ++++++++++++++++++++++---------------------- xen/common/memory.c | 2 +- xen/include/xen/ioreq.h | 26 ++++----- 9 files changed, 98 insertions(+), 98 deletions(-) diff --git a/xen/arch/x86/hvm/emulate.c b/xen/arch/x86/hvm/emulate.c index 21051ce..425c8dd 100644 --- a/xen/arch/x86/hvm/emulate.c +++ b/xen/arch/x86/hvm/emulate.c @@ -261,7 +261,7 @@ static int hvmemul_do_io( * an ioreq server that can handle it. * * Rules: - * A> PIO or MMIO accesses run through hvm_select_ioreq_server() to + * A> PIO or MMIO accesses run through ioreq_server_select() to * choose the ioreq server by range.
