2011-01-11agp/intel: Flush the chipset write buffers when changing GTT baseChris Wilson
Flush the chipset write buffers before and after adjusting the GTT base register, just in case. We only modify this value upon initialisation (boot and resume) so there should be no outstanding writes, however there are always those persistent PGTBL_ER that keep getting reported upon resume.

2010-10-27intel-gtt: maximize ggtt size on platforms that support thisDaniel Vetter
On VT-d supporting platforms the GGTT is allocated in a stolen mem section separate from graphcis stolen mem. The GMCH register contains a bitfield specifying the size of that region. Docs suggest that this region can only be used for GGTT and PPGTT. Hence ensure that the PPGTT is disabled and use the complete area for the GGTT. Unfortunately the graphics core on G33/Pineview can't cope with really large GTTs and the BIOS usually enables the maximum of 512MB. So don't bother with maximizing the GTT on these platforms.

2010-09-17drm/i915,agp/intel: Add second set of PCI-IDs for B43Chris Wilson
There is a second revision of B43 (a desktop gen4 part) floating around, functionally equivalent to the original B43, so simply add the new PCI-IDs. Bugzilla: https://bugs.freedesktop.org/show_bugs.cgi?id=30221 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: stable@kernel.org
2010-09-08intel-gtt: introduce intel_gtt_driverDaniel Vetter
Same idea as INTEL_INFO from drm/i915. This - reduces the dependancy on agp_driver - stops the what-does-IS_I965G-mean confusion (here it's just gen4, in drm/i915 it's gen >=4) - further prepares the separation of the fake agp driver from the rest.

2010-09-08agp/intel: make intel-gtt.c into a real source fileDaniel Vetter
Now that the disentangling is complete, stop including intel-gtt.c from intel-agp.c. The linux build system _really_ doesn't allow .c source files with the same name as the module. It fails with the following message when trying to build such a bugger: make[3]: Circular drivers/char/agp/intel-agp.o <- drivers/char/agp/intel-agp.o dependency dropped. Instead of renameing intel-agp.c I've simply created a new module out of intel-gtt.c. Renaming intel-agp.ko to something else is not an option for it will surely kill someones boot process. This also paves the way to use the gtt code without loading the agp driver. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
