Thomas Hellstrom eba67093f5 drm/ttm: Fix up io_mem_reserve / io_mem_free calling ... This patch attempts to fix up shortcomings with the current calling sequences. 1) There's a fastpath where no locking occurs and only io_mem_reserved is called to obtain needed info for mapping. The fastpath is set per memory type manager. 2) If the fastpath is disabled, io_mem_reserve and io_mem_free will be exactly balanced and not called recursively for the same struct ttm_mem_reg. 3) Optionally the driver can choose to enable a per memory type manager LRU eviction mechanism that, when io_mem_reserve returns -EAGAIN will attempt to kill user-space mappings of memory in that manager to free up needed resources Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>		14 years ago
