From 8c30eecc6769bee1e3acb485ad5f086a4d8a04b6 Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Tue, 2 Aug 2022 02:04:04 +0200 Subject: drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr} The field paddr of struct drm_gem_dma_object holds a DMA address, which might actually be a physical address. However, depending on the platform, it can also be a bus address or a virtual address managed by an IOMMU. Hence, rename the field to dma_addr, which is more applicable. In order to do this renaming the following coccinelle script was used: ``` @@ struct drm_gem_dma_object *gem; @@ - gem->paddr + gem->dma_addr @@ struct drm_gem_dma_object gem; @@ - gem.paddr + gem.dma_addr @exists@ typedef dma_addr_t; symbol paddr; @@ dma_addr_t paddr; <... - paddr + dma_addr ...> @@ symbol paddr; @@ dma_addr_t - paddr + dma_addr ; ``` This patch is compile-time tested with: ``` make ARCH={x86_64,arm,arm64} allyesconfig make ARCH={x86_64,arm,arm64} drivers/gpu/drm` ``` Acked-by: Sam Ravnborg Suggested-by: Laurent Pinchart Reviewed-by: Laurent Pinchart Signed-off-by: Danilo Krummrich Signed-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20220802000405.949236-5-dakr@redhat.com --- drivers/gpu/drm/shmobile/shmob_drm_crtc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/shmobile/shmob_drm_crtc.c') diff --git a/drivers/gpu/drm/shmobile/shmob_drm_crtc.c b/drivers/gpu/drm/shmobile/shmob_drm_crtc.c index bdf3e8841a40..4624c0aff51f 100644 --- a/drivers/gpu/drm/shmobile/shmob_drm_crtc.c +++ b/drivers/gpu/drm/shmobile/shmob_drm_crtc.c @@ -293,13 +293,13 @@ static void shmob_drm_crtc_compute_base(struct shmob_drm_crtc *scrtc, bpp = scrtc->format->yuv ? 8 : scrtc->format->bpp; gem = drm_fb_dma_get_gem_obj(fb, 0); - scrtc->dma[0] = gem->paddr + fb->offsets[0] + scrtc->dma[0] = gem->dma_addr + fb->offsets[0] + y * fb->pitches[0] + x * bpp / 8; if (scrtc->format->yuv) { bpp = scrtc->format->bpp - 8; gem = drm_fb_dma_get_gem_obj(fb, 1); - scrtc->dma[1] = gem->paddr + fb->offsets[1] + scrtc->dma[1] = gem->dma_addr + fb->offsets[1] + y / (bpp == 4 ? 2 : 1) * fb->pitches[1] + x * (bpp == 16 ? 2 : 1); } -- cgit
