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).

This allows us to pass the connector to the encoder creation functions, and avoid using a create_resources() callback since we can now call it directly. This can also potentially modify the connector ordering on nv50. On cards where the DCB connector and encoder tables are in the same order, things will be unchanged. However, there's some cards where the ordering between the tables differ, and in one case, leads us to naming the connectors "wrongly".

Init-compute-mem was the last piece missing for nv0x-nv3x card cold-booting. This implementation is somewhat lacking but it's been reported to work on most chipsets it was tested in.

BIOS scripts usually make an attempt to reset the AGP controller, however on some nv4x cards doing it properly involves switching FW off and on: if we do that without updating the AGP bridge settings accordingly (e.g. with the corresponding calls to agp_enable()) we will be locking ourselves out of the card MMIO space. Do it from nouveau_mem_reset_agp() before the init scripts are executed.

On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset. Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system. This allows kexec to work on a Power6/RN50 system.

I changed it to check if (freq < current_freq) directly. "best_error" is also unsigned so "best_error - 100" could be a large number instead of a negative. Since "error" is unsigned it is never less than a negative and so the cases where "best_error" is less than or equal to 100 are false.

For the later chipsets in the i965 family, only a 4k alignment is required. (So long as we do not start performing asynchronous flips.) Note the impact of this should be slight as on i965 we should be using a tiled frontbuffer for anything up to a 4096x4096 display. v2: compilation fixes and note that the docs do not exclude the G35 from the extra alignment.

This still leaves the AGP region and backing pages allocated, and perhaps more importantly, the object remains upon the various lists exposing us to memory corruption. I think this is the cause behind the use-after-free, such as Bug 15664 - Graphics hang and kernel backtrace when starting Azureus with Compiz enabled https://bugzilla.kernel.org/show_bug.cgi?id=15664 v2: Daniel Vetter reminded me that kernel space programming is never easy. We cannot simply spin to clear the pending signal and so must deferred the freeing of the object until later. v3: Run from the top level retire requests. v4: Tested with P(return -ERESTARTSYS)=.5 from i915_gem_do_wait_request() v5: Rebase against Eric's for-linus tree. v6: Refactor, split and add a comment about avoiding unbounded recursion.

Unless we reclaim it, our aperture for remapping buffer objects will be constrained. So clamp the stolen space to 32M and ignore the rest. Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15469 among others. Adding the ignored stolen memory back into the general pool using the memory hotplug code is left as an exercise for the reader.

The three remaining users in common code (open, ioctl and release) get converted to a new mutex, the drm_global_mutex, making the locking stricter than the big kernel lock. This may have a performance impact, but only in those cases that currently don't use DRM_UNLOCKED flag in the ioctl list and would benefit from that anyway. The reason why i810 and i830 cannot use drm_global_mutex in their mmap functions is a lock-order inversion problem between the current use of the BKL and mmap_sem in these drivers. Since the BKL has release-on-sleep semantics, it's harmless but it would cause trouble if we replace the BKL with a mutex. Instead, these drivers get their own ioctl wrappers that take the BKL around every ioctl call and then set their own handlers as DRM_UNLOCKED.
