From b12f601fe5f0e0cf37c4efd00c41a033dff67664 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 19 Apr 2017 20:24:41 +0200 Subject: [PATCH] gpu: host1x: select IOMMU_IOVA When IOMMU_IOVA is not built-in but host1x is, we get a link error: drivers/gpu/host1x/dev.o: In function `host1x_remove': dev.c:(.text.host1x_remove+0x50): undefined reference to `put_iova_domain' drivers/gpu/host1x/dev.o: In function `host1x_probe': dev.c:(.text.host1x_probe+0x31c): undefined reference to `init_iova_domain' dev.c:(.text.host1x_probe+0x38c): undefined reference to `put_iova_domain' drivers/gpu/host1x/cdma.o: In function `host1x_cdma_init': cdma.c:(.text.host1x_cdma_init+0x238): undefined reference to `alloc_iova' cdma.c:(.text.host1x_cdma_init+0x2c0): undefined reference to `__free_iova' drivers/gpu/host1x/cdma.o: In function `host1x_cdma_deinit': cdma.c:(.text.host1x_cdma_deinit+0xb0): undefined reference to `free_iova' This adds the same select statement that we have for drm_tegra.
