Besides the minimal improvement in reducing the execbuffer overhead, the real benefit is clarifying a few routines. Signed-off-by:Chris Wilson <chris@chris-wilson.co.uk>

A number of dragons have been seen lurking within the execbuffer code. The first step is then to isolate them from the rest and begin to scrutinise them in depth. Suggested by Daniel Vetter. Signed-off-by: -

Simply remove our accounting of objects inside the aperture, keeping only track of what is in the aperture and its current usage. This removes the over-complication of BUGs that were attempting to keep the accounting correct and also removes the overhead of the accounting on the hot-paths. Signed-off-by: -

Avoid evicting buffers that will be used later in the batch in order to make room for the initial buffers by pinning all bound buffers in a single pass before binding (and evicting for) fresh buffer. Signed-off-by:

This used to check the precondition that all fences were to be located in a mappable area, redundant now as those two parameters are combined into one. After pinning, we assert that the buffer is bound into the desired region. Signed-off-by: -

The pipe control object is allocated by the device for the sole use of the render ringbuffer. Move this detail from the general code to the render ring buffer initialisation. Signed-off-by: -

Having seen the effects of erroneous fencing on the batchbuffer, a useful sanity check is to record the fence registers at the time of an error. Signed-off-by: -

drivers/char/agp/intel-gtt.c:340:48: warning: duplicate const Signed-off-by: -
Chris Wilson authored
Combining map_and_fenceable revealed a bug in i915_gem_object_gtt_size() in that it always computed the appropriate fence size for the object regardless of tiling state which caused us to over-allocate linear buffers when binding to the GTT. Signed-off-by: -

This still uses the agp functions to actually reinstate the mappings (with a gross hack to make agp cooperate), but it wires everything up correctly for the switchover. The call to agp_rebind_memory can be dropped because all non-kms drivers do all their rebinding on EnterVT. v2: Be more paranoid and flush the chipset cache after restoring gtt mappings.

This is required to restore gtt mappings on resume when agp is gone. The right way to do this would be to make sturct drm_mm_node embeddable and use the allocation list maintained by the drm memory manager. But that's a bigger project. Getting rid of the per bo agp_mem will save more memory than this wastes, anyway. Signed-off-by:

The intel drm calls the chipset functions now directly. Userspace never called the corresponding ioctl, hence it can be killed, too. Cc: Dave Airlie <airlied@gmail.com> Signed-off-by:

i830_check_flags already disallows it, so no need to implement it in the write_entry function. Seems to be a remnant from i810 support. Signed-off-by:

Currently if we hit a pagefault when applying a user relocation for the execbuffer, we bail and return EFAULT to the application. Instead, we need to unwind, drop the dev->struct_mutex, copy all the relocation entries to a vmalloc array (to avoid any potential circular deadlocks when resolving the pagefault), retake the mutex and then apply the relocations. Afterwards, we need to again drop the lock and copy the vmalloc array back to userspace. v2: Incorporate feedback from Daniel Vetter. Reported-by:

Now that the stolen memory does not also steal entries from the GTT, we can use all the memory the BIOS set aside for the GPU. Signed-off-by: -

The GATT is a write-only set of registers, reading from them in the manner of i915_gtt_to_phys() is supposed to be undefined. However a simple solution exists as we allocate linear memory from the stolen area, we can simply add the block offset to the base register. As a side-effect we recover all the unused stolen GTT entries and so enlarge our aperture. Signed-off-by: -

After a GPU reset, the backlight controller registers may be also reset to 0. In that case we should restore those to the original values programmed by the BIOS. Note that we still lack the code to handle the case where the BIOS failed to program those registers at all... Signed-off-by: -
