From: Rob Clark <robdclark@xxxxxxxxxxxx> The driver should be in control of this. Signed-off-by: Rob Clark <robdclark@xxxxxxxxxxxx> --- It is possible that this was masking bugs (ie. not setting appropriate pgprot) in drivers. I don't have a particularly good idea for tracking those down (since I don't have the hw for most drivers). Unless someone has a better idea, maybe land this and let driver maintainers fix any potential fallout in their drivers? This is necessary for the next patch to fix VGEM brokenness on arm. drivers/gpu/drm/drm_gem.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/drm_gem.c b/drivers/gpu/drm/drm_gem.c index 8a55f71325b1..7d6242cc69f2 100644 --- a/drivers/gpu/drm/drm_gem.c +++ b/drivers/gpu/drm/drm_gem.c @@ -1110,7 +1110,7 @@ int drm_gem_mmap_obj(struct drm_gem_object *obj, unsigned long obj_size, vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND | VM_DONTDUMP; vma->vm_private_data = obj; - vma->vm_page_prot = pgprot_writecombine(vm_get_page_prot(vma->vm_flags)); + vma->vm_page_prot = vm_get_page_prot(vma->vm_flags); vma->vm_page_prot = pgprot_decrypted(vma->vm_page_prot); /* Take a ref for this mapping of the object, so that the fault -- 2.21.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
