drm/i915: disable ppgtt on snb when dmar is enabled

2012-04-02T13:59:07+00:00

Totally unexpected that this regressed. Luckily it sounds like we just
need to have dmar disable on the igfx, not the entire system. At least
that's what a few days of testing between Tony Vroon and me indicates.

Merge remote-tracking branch 'airlied/drm-fixes' into drm-intel-next-queued

2012-02-10T16:14:49+00:00

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.

agp/intel-gtt: export the gtt pagetable iomapping

2012-02-09T20:24:18+00:00

We need this because ppgtt page directory entries need to be in the
global gtt pagetable.

agp/intel-gtt: export the scratch page dma address

2012-02-09T20:23:18+00:00

To implement a PPGTT for drm/i915 that fully aliases the GTT, we also
need to properly alias the scratch page.

agp: fix scratch page cleanup

2012-01-26T18:36:48+00:00

In error cleanup of agp_backend_initialize() and in agp_backend_cleanup(),
agp_destroy_page() is passed virtual address of the scratch page. This
leads to a kernel warning if the initialization fails (or upon regular
cleanup) as pointer to struct page should be passed instead.

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.
