From: Wei Liu <li...@microsoft.com> Add an config file snippet which enalbes additional options useful for running the kernel in a Hyper-V guest.
The expected use case is a user provides an existing config file then executes `make hvconfig`. It will merge those options with the provided config file. Based on similar concept for Xen and KVM. Signed-off-by: Wei Liu <li...@microsoft.com> --- RFC: I only tested this on x86. Although the config options included in hv_guest.config don't seem to be arch-specific, we should probably move the ones not yet implemented on Arm to an x86 specific config file. --- Documentation/admin-guide/README.rst | 3 +++ kernel/configs/hv_guest.config | 33 ++++++++++++++++++++++++++++ scripts/kconfig/Makefile | 5 +++++ 3 files changed, 41 insertions(+) create mode 100644 kernel/configs/hv_guest.config diff --git a/Documentation/admin-guide/README.rst b/Documentation/admin-guide/README.rst index cc6151fc0845..d5f4389a7a2f 100644 --- a/Documentation/admin-guide/README.rst +++ b/Documentation/admin-guide/README.rst @@ -224,6 +224,9 @@ Configuring the kernel "make xenconfig" Enable additional options for xen dom0 guest kernel support. + "make hvconfig" Enable additional options for Hyper-V guest kernel + support. + "make tinyconfig" Configure the tiniest possible kernel.
