drm: implement helper functions for scanning lru list

2010-07-07T02:29:51Z

These helper functions can be used to efficiently scan lru list for eviction. Eviction becomes a three stage process: 1. Scanning through the lru list until a suitable hole has been found. 2. Scan backwards to restore drm_mm consistency and find out which objects fall into the hole. 3. Evict the objects that fall into the hole. These helper functions don't allocate any memory (at the price of not allowing any other concurrent operations). Hence this can also be used for ttm (which does lru scanning under a spinlock). Evicting objects in this fashion should be more fair than the current approach by i915 (scan the lru for a object large enough to contain the new object). It's also more efficient than the current approach used by ttm (uncoditionally evict objects from the lru until there's enough free space).

drm: sane naming for drm_mm.c

2010-07-07T02:27:53Z

Yeah, I've kinda noticed that fl_entry is the free stack. Still give it (and the memory node list ml_entry) decent names. Signed-off-by: Daniel Vetter Acked-by: Thomas Hellstrom Signed-off-by: Chris Wilson Signed-off-by: Dave Airlie

drm: kill drm_mm_node->private

drm: Add memory manager debug function

2009-12-10T05:28:06Z

drm_mm_debug_table will print the memory manager state in table allowing to give a snapshot of the manager at given point in time. Usefull for debugging. Signed-off-by: Jerome Glisse Signed-off-by: Dave Airlie

drm: Add search/get functions to get a block in a specific range

2009-12-10T05:09:01Z

These are required for changes to TTM. Signed-off-by: Jerome Glisse Signed-off-by: Dave Airlie

drm: include seq_file.h for debugfs builds.

Fixes a warning seen on powerpc. Signed-off-by: Dave Airlie

drm/mm: add ability to dump mm lists via debugfs

2009-09-01T23:39:43Z

This adds code to the drm_mm to talk to debugfs, and adds support to radeon to add the VRAM and GTT mm lists to debugfs. I tested with spinlock debugging and it doesn't give out. Signed-off-by: Dave Airlie

drm: Apply "Memory fragmentation from lost alignment blocks"

2009-06-18T23:01:12Z

also for the atomic path by using a common code-path. Signed-off-by: Thomas Hellstrom Signed-off-by: Dave Airlie

drm: Split out the mm declarations in a separate header. Add atomic operations.

2009-06-12T05:56:31Z

this is a TTM preparation patch, it rearranges the mm and add operations needed to do mm operations in atomic context. Signed-off-by: Thomas Hellstrom Signed-off-by: Dave Airlie
