From ed165a25292740d5d3ef7e78dc04a6a3402562aa Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Sat, 1 Jan 2005 20:03:15 +0000 Subject: Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It uses drm_pci_alloc/free for allocating/freeing the memory. Only implemented in the Linux DRM so far. --- linux-core/drm_vm.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'linux-core/drm_vm.c') diff --git a/linux-core/drm_vm.c b/linux-core/drm_vm.c index 9b49efdc..3372498b 100644 --- a/linux-core/drm_vm.c +++ b/linux-core/drm_vm.c @@ -232,6 +232,10 @@ void drm_vm_shm_close(struct vm_area_struct *vma) case _DRM_AGP: case _DRM_SCATTER_GATHER: break; + case _DRM_CONSISTENT: + drm_pci_free(dev, map->size, map->handle, + map->offset); + break; } drm_free(map, sizeof(*map), DRM_MEM_MAPS); } @@ -658,6 +662,9 @@ int drm_mmap(struct file *filp, struct vm_area_struct *vma) vma->vm_ops = &drm_vm_ops; break; case _DRM_SHM: + case _DRM_CONSISTENT: + /* Consistent memory is really like shared memory.
