From 1df6a2ebd75067aefbdf07482bf8e3d0584e04ee Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Thu, 30 Sep 2010 12:36:45 +0200 Subject: drm/ttm: Fix two race conditions + fix busy codepaths This fixes a race pointed out by Dave Airlie where we don't take a buffer object about to be destroyed off the LRU lists properly. It also fixes a rare case where a buffer object could be destroyed in the middle of an accelerated eviction. The patch also adds a utility function that can be used to prematurely release GPU memory space usage of an object waiting to be destroyed. For example during eviction or swapout. The above mentioned commit didn't queue the buffer on the delayed destroy list under some rare circumstances. It also didn't completely honor the remove_all parameter.

However, in order to maintain a stable kernel, we should prevent this known random memory corruption following driver unload. This should have very low impact on normal users who are unlikely to need to unload the i915 driver.

When changing modes atomically for kdb, this information must be saved and restored without disturbing user space as if nothing ever happened. There is a short cut used by this patch where gamma_store is used as the save space. If this turns out to be a problem in the future a pre-allocated chunk of memory will be required for each crtc to save and restore the LUT information.
