Hi, With the new ttm stuff, drm map handles (user_token in kernel space) is moving over to opaque 32 bit numbers to facilitate fast hash lookups of drm maps.
Some drivers (both 2D and 3D) used to assume that the 32-bit drm map handle was equal to the physical address of the region to map, whereas now it will be a page-aligned hashed value of an arbitrary kernel virtual address. Does anybody know about drivers that still makes use of the old assumption, and in that case is that something worth preserving? It's certainly possible to preserve the old behaviour for some 32-bit address ranges, but at some performance cost. /Thomas ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
