Currently, RPMSG_VIRTIO can only be enabled if some other kconfig option selects it. This does not allow it to be enabled for virtualized systems where Virtio RPMSG is available over Virtio MMIO or PCI transport.
This patch updates RPMSG_VIRTIO kconfig option so that we can enable the VirtIO RPMSG driver via menuconfig or defconfig. Signed-off-by: Anup Patel <[email protected]> --- Changes since v1: - Add depends on HAS_DMA to avoid build failures on archs (such as um) with NO_DMA=y. For most archs, HAS_DMA=y so having depends on HAS_DMA is fine. drivers/rpmsg/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/rpmsg/Kconfig b/drivers/rpmsg/Kconfig index 0fe6eac..65a9f6b 100644 --- a/drivers/rpmsg/Kconfig +++ b/drivers/rpmsg/Kconfig @@ -47,7 +47,8 @@ config RPMSG_QCOM_SMD platforms. config RPMSG_VIRTIO - tristate + tristate "Virtio RPMSG bus driver" + depends on HAS_DMA select RPMSG select VIRTIO -- 2.7.4
