dd2757f8b5 drm/i915: stop using dev->agp->base
For that to work we need to export the base address of the gtt
mmio window from intel-gtt. Also replace all other uses of
dev->agp by values we already have at hand.

effbc4fd8e Merge branch 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-core-next
Daniel Vetter wrote
First pull request for 3.5-next, slightly large than usual because new
things kept coming in since the last pull for 3.4.
Highlights:
- first batch of hw enablement for vlv (Jesse et al) and hsw (Eugeni). pci
 ids are not yet added, and there's still quite a few patches to merge
 (mostly modesetting). To make QA easier I've decided to merge this stuff
 in pieces.
- loads of cleanups and prep patches spurred by the above. Especially vlv
 is a real frankenstein chip, but also hsw is stretching our driver's
 code design. Expect more to come in this area for 3.5.
- more gmbus fixes, cleanups and improvements by Daniel Kurtz. Again,
 there are more patches needed (and some already queued up), but I wanted
 to split this a bit for better testing.
- pwrite/pread rework and retuning. This series has been in the works for
 a few months already and a lot of i-g-t tests have been created for it.
 Now it's finally ready to be merged.  Note that one patch in this series
 touches include/pagemap.h, that patch is acked-by akpm.
- reduce mappable pressure and relocation throughput improvements from
 Chris.
- mmap offset exhaustion mitigation by Chris Wilson.
- a start at figuring out which codepaths in our messy dri1/ums+gem/kms
 driver we actually need to support by bailing out of unsupported case.
 The driver now refuses to load without kms on gen6+ and disallows a few
 ioctls that userspace never used in certain cases. More of this will
 definitely come.
- More decoupling of global gtt and ppgtt.
- Improved dual-link lvds detection by Takashi Iwai.
- Shut up the compiler + plus fix the fallout (Ben)
- Inverted panel brightness handling (mostly Acer manages to break things
 in this way).
- Small fixlets and adjustements and some minor things to help debugging.

Regression-wise QA reported quite a few issues on ivb, but all of them
turned out to be hw stability issues which are already fixed in
drm-intel-fixes (QA runs the nightly regression tests on -next alone,
without -fixes automatically merged in). There's still one issue open on
snb, it looks like occlusion query writes are not quite as cache coherent
as we've expected. With some of the pwrite adjustements we can now
reliably hit this. Kernel workaround for it is in the works."

9edd576d89 Merge remote-tracking branch 'airlied/drm-fixes' into drm-intel-next-queued
Back-merge from drm-fixes into drm-intel-next to sort out two things:

- interlaced support: -fixes contains a bugfix to correctly clear
  interlaced configuration bits in case the bios sets up an interlaced
  mode and we want to set up the progressive mode (current kernels
  don't support interlaced). The actual feature work to support
  interlaced depends upon (and conflicts with) this bugfix.

- forcewake voodoo to workaround missed IRQ issues: -fixes only enabled
  this for ivybridge, but some recent bug reports indicate that we
  need this on Sandybridge, too. But in a slightly different flavour
  and with other fixes and reworks on top. Additionally there are some
  forcewake cleanup patches heading to -next that would conflict with
  currrent -fixes.

comment, (pg_start + mem->page_count) may wrap in case of AGPIOC_BIND,
and it is not checked at all in case of AGPIOC_UNBIND.  As a result, user

local DoS or privilege escalation.

b522f02184 agp: fix OOM and buffer overflow
page_count is copied from userspace.  agp_allocate_memory() tries to
check whether this number is too big, but doesn't take into account the
wrap case.  Also agp_create_user_memory() doesn't check whether
alloc_size is calculated from num_agp_pages variable without overflow.
This may lead to allocation of too small buffer with following buffer
overflow.

Another problem in agp code is not addressed in the patch - kernel memory
exhaustion (AGPIOC_RESERVE and AGPIOC_ALLOCATE ioctls).  It is not checked
whether requested pid is a pid of the caller (no check in agpioc_reserve_wrap()).
Each allocation is limited to 16KB, though, there is no per-process limit.
This might lead to OOM situation, which is not even solved in case of the
caller death by OOM killer - the memory is allocated for another (faked) process.

a70b95c017 agp: ensure GART has an address before enabling it
Some BIOSs (eg.  the AMI BIOS on the Asus P4P800 motherboard) don't
initialise the GART address, and pcibios_assign_resources() can ignore it
because it can be marked as a host bridge (see
https://bugzilla.kernel.org/show_bug.cgi?id=24392#c5 for details).  This
was handled correctly up to 2.6.35, but the pci_enable_device() cleanup in
2.6.36 96576a9e1a ("agp: intel-agp: do not use PCI resources before
pci_enable_device()") means that the kernel tries to enable the GART
before assigning it an address; in such cases the GART overlaps with other
device assignments and ends up being disabled.

This patch fixes https://bugzilla.kernel.org/show_bug.cgi?id=24392

Note that I imagine efficeon-agp.c probably has the same problem, but
I can't test that and I'd like to make sure this patch is suitable for
-stable (since 2.6.36 and 2.6.37 are affected).

cecd1455bc Revert "agp: AMD AGP is used on UP1100 & UP1500 alpha boxen"
This reverts commit f191f14407.

The AMD 751 and 761 chipsets are used on the UP1000, UP1100, and UP1500
OEM motherboards, but they neglect to do anything to make AGP work.

According to Ivan Kokshaysky:
There is quite fundamental conflict between the Alpha architecture and
x86 AGP implementation - Alpha is entirely cache coherent by design,
while x86 AGP is not (I mean native AGP DMA transactions, not a PCI over
AGP). There are no such things as non-cacheable mappings or software
support for cache flushing/invalidation on Alpha, so x86 AGP code won't
work on Nautilus.

So there's no point in allowing this driver to be configured on Alpha.

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.

201728429d intel-gtt: maximize ggtt size on platforms that support this
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.

e61cb0d5fd some clean up to intel-gtt.c
In commit e517a5e970 the call to
map_page_into_agp() got removed from intel_i830_setup_flush(), but the
counterpart call from intel_i830_fini_flush() to unmap_page_from_agp()
was left in place.

Additionally, the page allocated here never gets its physical address
used for sending to hardware, so there's no need to allocate it with
GFP_DMA32. Nor is __GFP_ZERO really necessary, as the page is used
only to store data to force flushing of some internal processor state.
