Subject: [PATCH RFC] kconfig: add hvconfig for Linux on Hyper-V
Date: Tue, 8 Oct 2019 14:15:08 +0100 [thread overview]
Message-ID: <20191008131508.21189-1-liuw@liuw.name> (raw)
From: Wei Liu <liuwe@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 <liuwe@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.
