Subject: [PATCH 11/12] swiotlb: move the SWIOTLB config symbol to lib/Kconfig
Date: Mon, 23 Apr 2018 19:04:18 +0200 [thread overview]
Message-ID: <20180423170419.20330-12-hch@lst.de> (raw)
In-Reply-To: <20180423170419.20330-1-hch@lst.de>
This way we have one central definition of it, and user can select it as
needed. Note that we also add a second ARCH_HAS_SWIOTLB symbol to
indicate the architecture supports swiotlb at all, so that we can still
make the usage optional for a few architectures that want this feature
to be user selectable.

WARNING: multiple messages have this Message-ID (diff)

Subject: [PATCH 11/12] swiotlb: move the SWIOTLB config symbol to lib/Kconfig
Date: Mon, 23 Apr 2018 19:04:18 +0200 [thread overview]
Message-ID: <20180423170419.20330-12-hch@lst.de> (raw)
In-Reply-To: <20180423170419.20330-1-hch@lst.de>
This way we have one central definition of it, and user can select it as
needed. Note that we also add a second ARCH_HAS_SWIOTLB symbol to
indicate the architecture supports swiotlb at all, so that we can still
make the usage optional for a few architectures that want this feature
to be user selectable.
Signed-off-by: Christoph Hellwig <hch@lst.de>
