That means, some of +the ioctls that aren’t upstream yet will need to be renumbered. This +also means we’ll break the user mode ABI for those non-upstream ioctl +functions. + +I’m planning to upstream the IPC import/export functions soon. So +lets renumber those to 0x1F and 0x20 so they will be just after the +new GWS function and upstreaming won’t need to renumber them again. +CROSS_MEMORY_COPY will probably never go upstream, so we can move +that to a higher number (0x22). DBG_TRAP will probably go upstream in +a few months. We can leave it at its current number (0x21) and avoid +breaking the debugger ABI. + +Change-Id: I8236909c0d41384065af5ed1ed59e4faceeb0bd4 +Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> +--- + include/uapi/linux/kfd_ioctl.h | 6 +++--- + 1 file changed, 3 insertions(+), 3 deletions(-) + +diff --git a/include/uapi/linux/kfd_ioctl.h b/include/uapi/linux/kfd_ioctl.h +index 3e4346530011..082f28493e14 100644 +--- a/include/uapi/linux/kfd_ioctl.h ++++ b/include/uapi/linux/kfd_ioctl.h +@@ -653,13 +653,13 @@ struct kfd_ioctl_cross_memory_copy_args { + AMDKFD_IOWR(0x1E, struct kfd_ioctl_alloc_queue_gws_args) + + #define AMDKFD_IOC_IPC_IMPORT_HANDLE \ +- AMDKFD_IOWR(0x1E, struct kfd_ioctl_ipc_import_handle_args) ++ AMDKFD_IOWR(0x1F, struct kfd_ioctl_ipc_import_handle_args) + + #define AMDKFD_IOC_IPC_EXPORT_HANDLE \ +- AMDKFD_IOWR(0x1F, struct kfd_ioctl_ipc_export_handle_args) ++ AMDKFD_IOWR(0x20, struct kfd_ioctl_ipc_export_handle_args) + + #define AMDKFD_IOC_CROSS_MEMORY_COPY \ +- AMDKFD_IOWR(0x20, struct kfd_ioctl_cross_memory_copy_args) ++ AMDKFD_IOWR(0x22, struct kfd_ioctl_cross_memory_copy_args) + + #define AMDKFD_IOC_DBG_TRAP \ + AMDKFD_IOW(0x21, struct kfd_ioctl_dbg_trap_args) +-- +2.17.1 + |
