From b85891bd6d1bf887b3398f4c44b7a30b37f4485e Mon Sep 17 00:00:00 2001 From: Junwei Zhang Date: Mon, 16 Jan 2017 13:59:01 +0800 Subject: drm/amdgpu: IOCTL interface for PRT support v4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Till GFX8 we can only enable PRT support globally, but with the next hardware generation we can do this on a per page basis. Keep the interface consistent by adding PRT mappings and enable support globally on current hardware when the first mapping is made. v2: disable PRT support delayed and on all error paths v3: PRT and other permissions are mutal exclusive, PRT mappings don't need a BO. v4: update PRT mappings durign CS as well, make va_flags 64bit Signed-off-by: Junwei Zhang Signed-off-by: Christian König Reviewed-by: Nicolai Hähnle Signed-off-by: Alex Deucher --- include/uapi/drm/amdgpu_drm.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/uapi') diff --git a/include/uapi/drm/amdgpu_drm.h b/include/uapi/drm/amdgpu_drm.h index 5797283c2d79..1c0ddf71193e 100644 --- a/include/uapi/drm/amdgpu_drm.h +++ b/include/uapi/drm/amdgpu_drm.h @@ -361,6 +361,8 @@ struct drm_amdgpu_gem_op { #define AMDGPU_VM_PAGE_WRITEABLE (1 << 2) /* executable mapping, new for VI */ #define AMDGPU_VM_PAGE_EXECUTABLE (1 << 3) +/* partially resident texture */ +#define AMDGPU_VM_PAGE_PRT (1 << 4) struct drm_amdgpu_gem_va { /** GEM object handle */ -- cgit v1.3-14-g43fede
