With the probe call in our dispatch table, we can now cut away the last three remaining members in the intel_gtt shared struct and so remove it completely. v2: Rebased on top of Daniel's series Signed-off-by: NBen Widawsky <ben@bwidawsk.net> Reviewed-by: NDamien Lespiau <damien.lespiau@intel.com> [danvet: bikeshed commit message a bit.] Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

We need to clean up the overlay first, before taking down the stolen memory allocator. This regression has been introducec in commit 80405138 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Nov 15 11:32:29 2012 +0000 drm/i915: Allocate overlay registers from stolen memory v2: Rework the patch a bit as suggested by Chris Wilson: - move the overlay teardown up, into the modeset cleanup - move the stolen mm takedown into i915_gem_cleanup_stolen Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: NChris Wilson <chris@chris-wilson.co.uk> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

The primary purpose of this was to debug some use-after-free memory corruption that was causing an OOPS inside drm/i915. As it turned out the corruption was being caused elsewhere and i915.ko as a major user of many objects was being hit hardest. Indeed as we do frequent the generic kmalloc caches, dedicating one to ourselves (or at least naming one for us depending upon the core) aids debugging our own slab usage.

Allow for the creation of GEM objects backed by stolen memory. As these are not backed by ordinary pages, we create a fake dma mapping and store the address in the scatterlist rather than obj->pages. v2: Mark _i915_gem_object_create_stolen() as static, as noticed by Jesse Barnes.

As FBC is commonly disabled due to limitations of the chipset upon output configurations, on many systems FBC is never enabled. For those systems, it is advantageous to make use of the stolen memory for other objects and so we defer allocation of the FBC chunk until we actually require it. This increases the likelihood of that allocation failing, but that in turns means that we are already taking advantage of the stolen memory! As well as delaying the allocation from driver initialisation until the first use of FBC, we also return the stolen block after we finish using it - allowing greater flexibility in our usage of stolen space. A side effect of this is that we can then attempt to allocate only the required amount of space (with a little slack to reduce reallocation rate and avoid fragmentation).

The routine to query the base of stolen memory was using the wrong registers and the wrong encodings on virtually every platform. It was not until the G33 refresh, that a PCI config register was introduced that explicitly said where the stolen memory was. Prior to 865G there was not even a register that said where the end of usable low memory was and where the stolen memory began (or ended depending upon chipset). Before then, one has to look at the BIOS memory maps to find the Top of Memory. Alas that is not exported by arch/x86 and so we have to resort to disabling stolen memory on gen2 for the time being. Then SandyBridge enlarged the PCI register to a full 32-bits and change the encoding of the address, so even though we happened to be querying the right register, we read the wrong bits and ended up using address 0 for our stolen data, i.e. notably FBC.

Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.

We slightly modify the initialisation sequence to move the initialisation of the memory managers earlier and in particular before probing outputs and detecting any existing output configuration. This is essential if we wish to track preallocated objects and preserve them whilst initialising GEM.
