Subject: [PATCH v5 03/16] swiotlb: Refactor swiotlb_create_debugfs
Date: Thu, 22 Apr 2021 16:14:55 +0800	[thread overview]
Message-ID: <20210422081508.3942748-4-tientzu@chromium.org> (raw)
In-Reply-To: <20210422081508.3942748-1-tientzu@chromium.org>

Split the debugfs creation to make the code reusable for supporting
different bounce buffer pools, e.g. restricted DMA pool.

Subject: [Intel-gfx] [PATCH v5 03/16] swiotlb: Refactor swiotlb_create_debugfs
Date: Thu, 22 Apr 2021 16:14:55 +0800	[thread overview]
Message-ID: <20210422081508.3942748-4-tientzu@chromium.org> (raw)
In-Reply-To: <20210422081508.3942748-1-tientzu@chromium.org>

Split the debugfs creation to make the code reusable for supporting
different bounce buffer pools, e.g. restricted DMA pool.
