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. The patch also removes "select RPMSG_VIRTIO" from various remoteproc kconfig options because it is now user selectable. Signed-off-by: Anup Patel <anup@xxxxxxxxxxxxxx> --- Changes since v2: - Remove "select RPMSG_VIRTIO" from various remoteproc kconfig options 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/remoteproc/Kconfig | 4 ---- drivers/rpmsg/Kconfig | 3 ++- 2 files changed, 2 insertions(+), 5 deletions(-) diff --git a/drivers/remoteproc/Kconfig b/drivers/remoteproc/Kconfig index df63e44..afb7628 100644 --- a/drivers/remoteproc/Kconfig +++ b/drivers/remoteproc/Kconfig @@ -28,7 +28,6 @@ config OMAP_REMOTEPROC depends on OMAP_IOMMU select MAILBOX select OMAP2PLUS_MBOX - select RPMSG_VIRTIO help Say y here to support OMAP's remote processors (dual M3 and DSP on OMAP4) via the remote processor framework. @@ -58,7 +57,6 @@ config DA8XX_REMOTEPROC tristate "DA8xx/OMAP-L13x remoteproc support" depends on ARCH_DAVINCI_DA8XX depends on DMA_CMA - select RPMSG_VIRTIO help Say y here to support DA8xx/OMAP-L13x remote processors via the remote processor framework. @@ -79,7 +77,6 @@ config DA8XX_REMOTEPROC config KEYSTONE_REMOTEPROC tristate "Keystone Remoteproc support" depends on ARCH_KEYSTONE - select RPMSG_VIRTIO help Say Y here here to support Keystone remote processors (DSP) via the remote processor framework. @@ -133,7 +130,6 @@ config ST_REMOTEPROC depends on ARCH_STI select MAILBOX select STI_MBOX - select RPMSG_VIRTIO help Say y here to support ST's adjunct processors via the remote processor framework. 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 -- To unsubscribe from this list: send the line "unsubscribe linux-remoteproc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
